+`reins do '<goal>'` hands a small browser task to TypeSafe's Jev model: it reads the page, picks each click, field and dropdown in about 0.2 s, and types only the values the agent passed with `--fill`. It stops and prints the exact next command for risky clicks (buy, send, delete, ...), missing values, dialogs, leaving the site, or no progress. `--continue` resumes the run, and `--confirm '<label>'` pre-approves a click. Exit codes: 0 done, 2 stopped for input, 1 error. On the extension side: the `jev_observe` / `jev_act` handlers (site tier `full`), per-tab JS dialog tracking, and a pre-action re-check of each chosen element. Jev can also submit a search field with Enter (`SUBMIT_SEARCH`, search-like fields only), a click that opens a new tab moves the run to that tab, three stale acts in a row stop the run as `stuck`, and the summary line reports the Jev input tokens used. A click on a link that opens a new tab (`target="_blank"`) — from `reins click` or `reins do` — no longer lets Chrome raise its window over the app you are working in: the extension opens the tab itself, next to the current one and active; `reins click` reports it as `ok — opened tab <id> (now active)` (`openedTabId` in `--json`).

+# `reins do` vs. Claude driving reins step by step
+
+Measured 2026-09-28 on 38 browsing tasks in the maintainer's real Chrome. One
+arm hands the whole goal to `reins do`: TypeSafe's Jev model picks every
+action. The other arm has Claude Code drive the same kind of tab with reins
+step commands, one shell call per command. Both arms are scored by the same
+independent JavaScript check on the page the run ended on.
+
+This replaces the first version of this benchmark (4 tasks, 2026-09-27),
+which is summarised at the end under
+[Earlier version of this benchmark](#earlier-version-of-this-benchmark-v1).
+
+Read [Limitations](#limitations) before quoting any number from this page.
+
+The runs behind these numbers: `reins do` on the 30 dev tasks, 5 runs each, on
+the final code (e9331fa); `reins do` on the 8 unseen holdout3 tasks, 5 runs
+each, the set's first and only run (f1af855, before round 5); Claude step by
+step on all 38 tasks, 3 runs each. Raw run files aren't kept in the repo; the
+commands under [Reproduce](#reproduce) regenerate them.
+
+The runner is [`packages/cli/scripts/bench-do.mjs`](../../packages/cli/scripts/bench-do.mjs);
+the tasks, their goals and their checks are in
+[`packages/cli/scripts/bench/tasks.mjs`](../../packages/cli/scripts/bench/tasks.mjs).
+
+## Headline
+
+- **Dev set (30 tasks, tuned on for five rounds):** `reins do` passed
+  **124 of 150 runs (82.6%)**. Claude step by step passed 81 of 90 (90%);
+  81 of 87 (93.1%) without fx-newtab, a task its rules made impossible (see
+  [Results](#results)).
+- **Unseen set (holdout3, 8 tasks, never looked at while fixing):** `reins do`
+  passed **35 of 40 runs (87.5%)** on its first and only run. Claude step by
+  step passed 21 of 24 (87.5%).
+- **Speed and cost, on the 30 tasks both arms passed at least once:** the
+  median task was **4.6x faster** with `reins do` (range 2.4x to 22.6x) and
+  **111x cheaper** in model spend (range 44x to 535x). Pooled over those
+  tasks' passing runs, the median `reins do` run took 5.7 s and the median
+  Claude run 24.5 s. The cost counts only Jev for `reins do`; the calling
+  agent's own turn is not in it.
+- **The self-check:** of the 166 `reins do` runs that ended `done`, 17 were
+  wrong, and all 17 carried a self-check under 0.5 ("unsure"); 20 of the 149
+  right ones (13%) were marked unsure too.
+
+In total the `reins do` arm made 1,106 Jev calls over 190 runs for 7,434,019
+input tokens, about $0.32. The step-by-step arm spent $21.83 of Claude over
+114 runs.
+
+Each arm also failed tasks the other passed. `reins do` never passed
+fx-datepicker, fx-filters, arxiv, fx-orders or xe; Claude never passed
+openlibrary or fx-wizard (and could not attempt fx-newtab). Why, per task, is
+under [Limitations](#limitations) and
+[Where step by step failed](#where-step-by-step-failed-and-reins-do-passed).
+
+## Method
+
+**The suite.** 38 tasks in two tiers.
+
+- **Fixture tier (11 tasks):** local pages served by the runner on
+  127.0.0.1, each built around one widget that trips browser agents:
+  an autocomplete that only commits on a picked suggestion, a calendar
+  popover with a Done button, a consent modal over a search form, a
+  search with a language filter and a sort menu, a link that opens a new
+  tab, a three-step form, a "Delete draft" button (the correct outcome is a
+  stop), a tabbed settings panel with switches and a Save button, a
+  paginated table whose target row is on page 2, an FAQ accordion with a
+  feedback vote, and a modal project wizard with a custom radio group.
+  The pages copy real sites' markup (`role=listbox` options, `menuitemradio`
+  menus, `role=switch`, `role=radio` cards).
+- **Live tier (27 tasks):** public sites, no logins, no purchases: Google
+  Flights, Wikipedia, GitHub search, BBC Weather, arXiv, npm, MDN, Cambridge
+  Dictionary, Hugging Face, Amazon, Hacker News, Wolfram|Alpha, the Python
+  docs, PyPI, a date calculator, lit.dev, MusicBrainz, Open Library,
+  crates.io, IANA's root zone database, OpenStreetMap, Project Gutenberg,
+  HN Search (Algolia), Debian packages, the Rust std docs, pkg.go.dev and
+  xe.com.
+
+**The checks.** Every task has a JavaScript check evaluated in the tab the
+run ended on (the new tab, when a link opened one). Each check was validated
+without `reins do` before the task was used: false on the start page, false
+on near-miss states (search run but not sorted, the wrong edition opened,
+the date picked but not confirmed, a second project created), true on a goal
+state reached by URL or by driving the page with `reins eval`. The checks and
+a plain-words note for each are in `tasks.mjs`.
+
+**A pass.** A run passes only when the check returns true and the arm
+finished on its own inside its time limit. A timeout never counts, even if
+the page ended up right (none happened in these runs). For fx-risky the
+correct outcome is a stop before the delete: `reins do` must end
+`risky_action` and the draft must still exist; Claude, which has no status,
+passes when the page check says the draft still exists and no confirm prompt
+opened.
+
+**Runs.** `reins do`: 5 runs per task. Claude: 3 runs per task, because each
+run costs about a hundred times more. Every run opens the task's start URL in
+a fresh tab, waits 2 s outside the clock, then times the arm from spawn to
+exit. Times are the runner's wall clock (`ms`).
+
+**The arms.**
+
+- **`reins do`:** one call, `reins do '<goal>' --fill name=value … --timeout
+  60 --tab <id> --json` (timeout 90 s for flights, amazon, wolframalpha and
+  xe). Jev picks each action; reins validates every answer and re-checks
+  every element before acting. At most 30 steps.
+- **Claude step by step:** `claude -p` (Claude Code 2.1.283, model
+  claude-opus-5-5) with the same goal and fill values in its prompt, allowed
+  only the reins step commands (snapshot, click, type, fill, select, press,
+  hover, scroll, wait, text, screenshot), one command per Bash call,
+  `--restricted` with an explicit allowlist, `reins do` denied, no
+  navigation by URL, told not to touch any other tab, told to stop before
+  anything irreversible, and capped at $2 per run (no run hit the cap; the
+  dearest was $0.91). Its cost is Claude Code's reported
+  `total_cost_usd` for the whole session.
+
+**Dev and holdout.** The dev set is what the fixes were tuned against. A
+holdout set is used once: its first run is the generalisation number, and
+after it the set has been seen, its failures discussed, and it is folded into
+dev. That happened twice. Holdout v1 (7 tasks) was folded in after its first
+run (25/35 on 48c758d); holdout2 (8 tasks) after its first run (16/40 on
+3c8a364). Holdout3 (8 tasks) was frozen on 2026-09-28 while HEAD was f1af855,
+before any `reins do` run on it, and its checks were validated without
+`reins do`. Its one run is the unseen number on this page. It was measured on
+f1af855; round 5's two changes came after it.
+
+**Machine and network.** The maintainer's laptop (macOS), reins 0.5.0, Node
+v24.18.0, on a residential network in India. TypeSafe runs Jev on the US West
+Coast, so every Jev call crossed the Pacific, and the `reins do` times include
+that. Runs on 2026-09-28 (UTC): holdout3 11:31 to 11:37, the xe re-run 11:37,
+dev 11:41 to 12:07, Claude 12:11 to 13:42.
+
+**Money.** Jev is priced at $0.042 per million input tokens, output free
+([TypeSafe's announcement](https://typesafe.ai/blog/introducing-system-one-models-and-jev),
+read 2026-09-27; TypeSafe says it cannot prove the price is not subsidised).
+Tokens are the API's own `usage.input_tokens`, summed per run, as
+`reins do --json` reports them in `inputTokens`.
+
+**Arithmetic.** Medians are over passing runs only, lower-middle for even
+counts (the runner's rule). Times are shown to 0.1 s. Jev cost per run is
+rounded up to the next $0.00001 and Claude cost per run rounded down to the
+$0.001, so neither rounding favours `reins do`. Speed-ups and cost ratios are
+computed from unrounded medians and truncated, never rounded up.
+
+## Results
+
+`reins do` columns: runs passed, then the median time, Jev input tokens and
+Jev cost of the passing runs. Claude columns: runs passed, then the median
+time, cost and turns of the passing runs. Speed-up and cost ratio are Claude's
+median over `reins do`'s, shown only where both arms passed at least once.

+1. fx-newtab is not a fair comparison. Its link opens the docs in a new tab,
+   and the step-by-step prompt forbids touching any tab but the one it was
+   given, so Claude stopped every time and said so. It is in the Claude
+   totals below, and the totals are also given without it.
+2. fx-risky's correct outcome is a stop. `reins do` ended `risky_action` 5 of
+   5 times without clicking. Claude stopped before the delete 3 of 3 times.
+   The runner first scored those 3 Claude runs as failures, applying a
+   `reins do`-only status rule to them; they are counted here by the page
+   check, as the runner now does (e382fbd).
+3. One passing run only, so that median is a single sample: mdn's Claude
+   figures, huggingface's `reins do` figures.
+4. Every debian run ended with status `left_site`, not `done`: the search
+   form on www.debian.org submits to packages.debian.org, and on f1af855
+   `reins do` stopped there as a site change. The page it stopped on was the
+   goal, so the check passes. Round 5 treats a leading `www.` as the same site
+   (8d69688); a later confirmation run ended `done` 5 of 5, but that run is
+   not counted, because the holdout is only measured once.
+
+Totals:
+
+| set | tier | `reins do` | Claude | Claude without fx-newtab |
+|---|---|---|---|---|
+| dev | fixture | 30/45 | 23/27 | 23/24 |
+| dev | live | 94/105 | 58/63 | 58/63 |
+| dev | all | **124/150 (82.6%)** | **81/90 (90%)** | 81/87 (93.1%) |
+| holdout3 | fixture | 10/10 | 3/6 | 3/6 |
+| holdout3 | live | 25/30 | 18/18 | 18/18 |
+| holdout3 | all | **35/40 (87.5%)** | **21/24 (87.5%)** | 21/24 |
+| both | all | 159/190 | 102/114 | 102/111 |
+
+Per set, the median task speed-up is 4.2x on dev (24 tasks) and 5.4x on
+holdout3 (6 tasks); the median cost ratio is 111x on dev and 105x on
+holdout3.
+
+Spend:
+
+- `reins do`, dev: 901 Jev calls, 6,256,057 input tokens, $0.263.
+- `reins do`, holdout3: 205 Jev calls, 1,177,962 input tokens, $0.050.
+- Claude, all 38 tasks: 114 runs, 1,728 turns, $21.83. The dearest run was
+  openlibrary #1 (52 turns, $0.91, failed); the slowest was openlibrary #3
+  (318.9 s, failed).
+
+For reference, on the same code as the holdout3 run (f1af855) the dev set
+scored 122/150 (81.3%).
+
+### The self-check
+
+Every `done` is put back to Jev once as a yes/no question ("every
+requirement in the goal is visibly satisfied on this page"), and the answer's
+probability is returned as `doneConfidence`. Below 0.5 the human output reads
+`done (unsure: self-check 0.43)` and the `next:` line says to verify.
+Recomputed from the per-run `result.json` files of the dev and holdout3 runs:
+
+| `done` runs | right (check passed) | wrong (check failed) |
+|---|---|---|
+| self-check 0.5 or more | 129 | 0 |
+| self-check under 0.5 ("unsure") | 20 | 17 |
+| total | 149 | 17 |
+
+- The 17 wrong ones: fx-filters ×5 (0.32 to 0.49), fx-datepicker ×5 (0.12
+  to 0.14), arxiv ×5 (0.38 to 0.45), github ×1 (0.44), huggingface ×1
+  (0.08). The highest, 0.49, sits one hundredth under the line.
+- The 20 right-but-unsure ones are four whole tasks: cookies ×5 (0.39 to
+  0.44), fx-newtab ×5 (0.38 to 0.49), wolframalpha ×5 (0.11 to 0.18) and
+  gutenberg ×5 (0.27 to 0.38). Unsure means "check the page", not "failed".
+- The three `stuck` runs (huggingface) carried a self-check of 0.04. Other
+  stops (`blocked`, `budget`, `needs_text`, `left_site`, `risky_action`)
+  carry none.
+
+### Where step by step failed and `reins do` passed
+
+Read from each failed run's final reply. Several of these point at reins'
+own step commands rather than at Claude's reasoning: `reins snapshot`, the
+command the step-by-step arm reads pages with, does not look inside shadow
+roots, while `reins do`'s observation does (it learned to in rounds 3 and 4,
+below).
+
+- **fx-newtab, 0/3.** The link opens a new tab; the prompt forbids other
+  tabs. Claude stopped and asked (3 to 4 turns). Not a fair task for this arm.
+- **openlibrary, 0/3.** Run 1 (52 turns, $0.91) searched but could never
+  open the "Sort by" menu: its options are inside a web component and never
+  appeared in a snapshot. Run 2 went through Advanced Search, landed on a
+  "Verify you are human" page and stopped rather than click it. Run 3 never
+  found the search field (it sits in a web component's modal) and stopped on
+  the home page.
+- **fx-wizard, 0/3.** Runs 1 and 2: clicking the "Team" visibility card came
+  back "element has zero size", Next still advanced with the default
+  Private, and Back and Close could not be used; Claude stopped on the review
+  step rather than create a Private project. Run 3 pressed Enter and then
+  Space on "Create project", both worked, and it created the project twice
+  (the check wants exactly one); Claude noticed and reported it.
+- **mdn, 1/3.** Runs 2 and 3 never found MDN's search box (a web component):
+  the search button reported zero size, `reins press /` was rejected as an
+  unknown key, and no selector reached the input. Run 1 got there in 34
+  turns.
+- **fx-settings, 2/3.** Run 2 saw the switches without names, a click on
+  the right one reported zero size, and a selector probe toggled a different
+  switch; Claude stopped without saving and said which switch might have
+  changed.
+
+No step-by-step run hit its $2 cap or the runner's 600 s limit; each
+failure is a stop Claude chose, with a reply saying why.
+
+## How it got here
+
+`reins do` was tuned in five rounds on the dev set. Each change was tried
+alone and A/B'd on the whole dev set (3 runs per task in round 1, 5 after
+that), and kept when the total rose by at least 3 runs with no task at 4/5 or
+better falling below 3/5 and fx-risky still stopping every time. Three changes
+were kept below that bar on judgment, because their target task moved from
+0/5 and the drops elsewhere were traced to unrelated coin flips; they are
+marked below and were flagged to the maintainer at the time. Tasks were only
+ever replaced or corrected when the task itself was broken (a past date, a
+checker bug, a page TypeSafe's API refused, a missing fill), never because
+`reins do` failed them.
+
+The dev set grew as holdouts were folded in, so the pass rates below are not
+one series on one set.
+
+| stage | code | dev set | dev result | holdout first run |
+|---|---|---|---|---|
+| baseline | 7b9d105 | 15 tasks × 3 | 26/45 (57.7%) | |
+| after round 1 | 031e35c | 15 × 3 | 33/45 (73.3%) | |
+| after round 2 | 307e204 | 15 × 5 | 61/75 (81.3%) | |
+| holdout v1 run | 48c758d | 15 × 5 | 58/75 (77.3%) | holdout v1: 25/35 (71.4%) |
+| after round 3 | 3c8a364 | 22 × 5 | 87/110 (79.0%) | holdout2: 16/40 (40%) |
+| round 4 start | 3c8a364 | 30 × 5 | 101/150 (67.3%) | |
+| after round 4 | f1af855 | 30 × 5 | 122/150 (81.3%) | holdout3: 35/40 (87.5%) |
+| after round 5 | e9331fa | 30 × 5 | 124/150 (82.6%) | |
+
+The kept changes, with what each moved in its own A/B:
+
+| change | commit | round | what it moved |
+|---|---|---|---|
+| "Accept" inside a cookie or consent banner is not a risky click | ffdb1b9 | 1 | 26 to 27 of 45; lets consent walls like Cambridge's be dismissed without the goal naming the button |
+| The observation waits for a loading or navigating tab, and re-attaches after Chrome drops the debugger session | 384ce2b | 1 | amazon 1/3 to 3/3; datecalc's page became readable at all |
+| A stop verdict right after typing a search query submits it first | cc8217a | 1 | flights 1/3 to 2/3; github's "blocked with the query typed" runs became passes |
+| After a click or a typed value, wait for the page to settle | 031e35c | 1 | flights 2/3 to 3/3, github 0/3 to 2/3, huggingface 1/3 to 2/3 (npm 3/3 to 2/3) |
+| Type key by key, and resume after a dropped debugger session | d3401e3 | 2 | fields that rewrite their value on keyup keep it; 52 to 55 of 75, the gain on the noisy tasks |
+| Name an unlabelled control by its table row or group, never by its options | 547849b | 2 | datecalc 0/20 to 8/10 over two runs (kept below the bar) |
+| DONE self-check (307e204), then report-only (48c758d) | 307e204, 48c758d | 2 | no pass moved; refusing a DONE never changed an outcome, so it now only reports `doneConfidence` |
+| A rounded-probability tie is not an unusable answer | 21a1fcf | 2 to 3 | removes an `error` stop seen in about 1 run in 6 in round 2 |
+| The observation reads open shadow roots | 08b668d | 3 | mdn 0/5 to 5/5 (kept below the bar) |
+| A stuck run is self-checked and ends `done` when its page is the goal | 3c8a364 | 3 | changed no outcome in its A/B; adds a self-check to `stuck` results |
+| A control is named by what its shadow root or slot renders | 3c4e846 | 4 | lit 0/5 to 4/5 (kept below the bar) |
+| A link to a new tab is opened by the extension, not by Chrome | a77ab0d | 4 | no pass change; Chrome no longer raises itself over the user's app when a run follows a `target=_blank` link |
+| Off-screen pagers and controls named by a goal word are in the observation | e9d0438 | 4 | iana 0/5 to 5/5; +8% tokens per call |
+| The observation waits for in-flight XHR and fetch requests | 47840f2 | 4 | osm 2/5 to 5/5; median run +20% |
+| No refocus click on the field just typed into, and clicks reach slotted web-component controls (a pair) | f1af855 | 4 | openlibrary 0/5 to 4/5; each half alone moved nothing |
+| A leading `www.` never makes a different site | 8d69688 | 5 | cannot move dev; debian `left_site` to `done` in a confirmation run (not counted) |
+| A field whose fill head says NONE retargets to a field whose head names a fill | e9331fa | 5 | fired on no dev run; did not fix xe |
+
+Round 5's total rose 122 to 124, which the traces put down to noise on
+wolframalpha: neither round-5 mechanism fired on a dev task.
+
+Tried and reverted (each with its A/B in the fix-loop log):
+
+- Observe settle without the re-attach: fx-form 3/3 to 1/3 (a password-manager
+  frame drops the debugger session). Replaced by the version with re-attach.
+- Offer the "Open field" click only on fields that open something: flights
+  2/3 to 0/3.
+- Stale-element guard scoped to row containers: no change (30 vs 30).
+- Page text joined per block, tried twice: arxiv's failure changed shape
+  but did not turn into a pass; no gain.
+- Row/group naming, first try: reverted on a github swing, kept in round 2
+  after a pooled re-test (above).
+- Rounded-tie tolerance, first two tries: no gain because the error is
+  rare; kept later (21a1fcf) because the error is real.
+- Key-by-key typing without the resume: fx-form 5/5 to 1/5.
+- A 300 ms grace for a click's navigation to start: no gain.
+- Stable select option ids, and refusing to re-select the current option:
+  datecalc 4/5 to 2/5 and 1/5.
+- A stuck self-check that credits the run's recorded actions: no outcome
+  changed.
+- The refocus rule alone and the slotted-click fix alone: no gain each;
+  kept together.
+
+## Limitations
+
+**Tasks `reins do` still fails, and why (from the traces):**
+
+- **fx-filters, 0/5.** Jev types the query, clicks the "TypeScript" filter
+  before submitting it (the page drops unsubmitted text, as GitHub does),
+  sorts, retypes and submits. The final URL has the query and the sort but no
+  language filter. Every run ends `done`, self-check 0.32 to 0.49.
+- **fx-datepicker, 0/5.** Jev opens the calendar, goes forward two months,
+  picks November 18, then answers DONE (in run 1, 0.69 against CLICK 0.31)
+  without pressing the calendar's Done button, which is in its observation. Every
+  run ends `done`, self-check 0.12 to 0.14.
+- **arxiv, 0/5.** Jev searches, then opens arXiv:2609.13531, a different
+  paper whose title starts with the same words. Earlier traces showed the
+  wanted paper is not on the newest-first results page at all, and the sort
+  control is offered and never chosen. Every run ends `done`, self-check 0.38
+  to 0.45.
+- **fx-orders, 0/5.** The order is on page 2 of a table. The pager ("2",
+  "Next page") is in the viewport and among Jev's click candidates (checked
+  against the screenshot and trace in round 4), and Jev answers
+  BLOCKED (0.94 to 0.95) at step 0, every run. No self-check runs on a
+  `blocked` stop; the stop itself is the signal.
+- **huggingface, 1/5.** The page has two search boxes. In 4 runs Jev typed
+  into the site-wide one, whose Enter opens the top model page, then clicked
+  "Open Search…" until it was `stuck` (×3, self-check 0.04) or answered
+  `done` there (×1, self-check 0.08). The one pass used the model list's own
+  "Filter by name" field.
+- **github, 4/5.** The miss typed the query, then followed the "advanced
+  search" link, which drops it; the results were TypeScript by stars without
+  "browser automation". `done`, self-check 0.44. After typing, Jev's choice
+  between that link and giving up (which reins turns into a submit) is a
+  near tie, so this flips from run to run.
+- **datecalc, 4/5.** The miss clicked Calculate before setting the end day,
+  then flipped the end-day select between 1 and 2 until the 30-step budget
+  ran out (`budget`).
+- **xe, 0/5 (holdout3).** Stops `needs_text` at step 0: xe gives its amount
+  input the label "Receiving amount", the same label as the converted
+  output, so no field matches the `amount` fill. The xe task first lacked
+  the currency fills; with them added, a re-run was still 0/5. Unsolved: overriding a
+  site's explicit label with nearby text is not a rule we could make general.
+
+**`done` is Jev's opinion.** On this suite every wrong `done` was marked
+unsure and no sure `done` was wrong, but that is 166 runs on 38 tasks, and
+the 17 wrong ones come from 5 tasks. Verify the page before reporting
+success, and treat an unsure `done` as a request to look.
+
+**Every text value comes from `--fill`.** `reins do` never makes up text.
+A field the fills do not cover stops the run with `needs_text`; a site that
+mislabels its fields (xe) stops it even when the value was given.
+
+**What it can see and do.** It reads open shadow roots, never closed ones.
+Links that open a new tab are opened by the extension, but a page that opens
+a tab from script (`window.open`) can still bring Chrome to the front. The
+risky-click stop is a heuristic on English words (buy, pay, send, delete…)
+and unlabelled buttons; other languages and odd labels can slip past it.
+
+**A small benchmark.** 38 tasks, one machine, one network, one day. 5 runs
+per task for `reins do`, 3 for Claude, so one run is 20 or 33 points on a
+task. Live sites change: a different first story on Hacker News, a changed
+search index or a new consent banner can move a task tomorrow. The fixture
+pages were written for this benchmark, and they, the checks and every fix
+were written by Claude agents working for the maintainer.
+
+**Tuned on dev.** Five rounds of fixes were tuned against the dev set, so
+its 82.6% is an optimistic number. The unseen figure (35/40) is the one that
+says how it generalises, and it was measured on f1af855, before round 5. It
+is 8 tasks: one task (xe) is 5 of its 40 runs, and its 5 debian passes ended
+`left_site` rather than `done` (note 4 under Results).
+
+**What the cost comparison leaves out.** The Jev figure is only Jev. The
+agent that calls `reins do` still spends its own turn to issue the command,
+read the result and verify the page, and that is not counted. The Claude
+figure is the whole Claude Code session: its own system prompt and tool
+definitions included (17 of the 114 replies mention the maintainer's
+claude.ai connectors, so their definitions were in the context too).
+
+**What the step-by-step arm measures.** It is Claude plus reins' step
+commands, and some of its failures are the step commands': `reins snapshot`
+does not read shadow roots (mdn, openlibrary) and reported "zero size" on
+controls in fx-wizard and fx-settings. A better step toolkit, or a Claude
+allowed to navigate by URL or use other tabs, would score higher and differ
+in speed and cost.
+
+**Privacy.** `reins do` sends the goal, your `--fill` names and values, the
+tab's URL and title, the visible text and the labels and values of the
+page's controls to TypeSafe. The full list is in
+[the `reins do` section of the security page](https://reins.tech/docs/security#reins-do)
+and [PRIVACY.md](../PRIVACY.md). The step-by-step arm sends page content to
+Anthropic. Either way it is opt-in.
+
+## Reproduce
+
+```bash
+# reins do on the dev set, 5 runs per task, with the Jev trace per run
+REINS_JEV_TRACE=/tmp/jev-trace.jsonl reins restart
+node packages/cli/scripts/bench-do.mjs --arm do --set dev --runs 5 \
+  --trace /tmp/jev-trace.jsonl --out r5.json
+
+# reins do on holdout3 (no longer unseen: it has been run once)
+node packages/cli/scripts/bench-do.mjs --arm do --set holdout3 --runs 5 --out h3.json
+
+# Claude step by step on every task, 3 runs per task
+node packages/cli/scripts/bench-do.mjs --arm manual --set all --runs 3 --out manual-v2.json
+```
+
+Other flags: `--tier fixture|live`, `--tasks id1,id2`,
+`--claude-budget-usd 2`, `--out-dir` (per-run folders with `result.json`, a
+screenshot and the Jev trace lines), and `--dry` for a self-test with no
+browser and no spend.
+
+It needs a TypeSafe key (`reins key set typesafe`) for the `reins do` arm
+and `claude` on PATH for the other. It costs money: about $0.32 of Jev for
+the 190 `reins do` runs here, $21.83 of Claude for the 114 step-by-step runs.
+It opens tabs in your real browser, in the foreground, for the whole run
+(about 25 minutes for dev, 5 for holdout3 and 90 for the Claude arm here). The fixture
+tier needs nothing but the runner, which serves the pages itself.
+
+## Earlier version of this benchmark (v1)
+
+The first version (2026-09-27) ran 4 live tasks (flights, wikipedia,
+github, cookies) 5 times per arm, on the builds of that day. On the build
+that shipped then (87ac8b8) `reins do` passed 14/20 and Claude step by step
+19/20; github was 1/5 for `reins do` (the advanced-search detour above), and
+on the tasks it passed `reins do` was 4.6x to 7.9x faster. It had no holdout
+set and no fixture tier, which is why v2 exists.

-# Audit Log (`reins audit`) Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Every browser command reins executes — and every one policy blocks — leaves one structured, redacted JSONL line the user can review with `reins audit`.
-
-**Architecture:** The extension's dispatch gate already resolves the target tab, host, and tier; it stamps them onto the response frame as optional `meta`. The daemon composes the full audit record (timestamp, method, redacted params, browser, outcome, duration) and appends it to `~/.reins/logs/audit-YYYY-MM-DD.jsonl`. `reins audit` reads those files directly — no daemon needed. Spec: `docs/superpowers/specs/2026-07-11-audit-log-design.md`.
-
-**Tech Stack:** TypeScript, zod (protocol schemas), vitest, pnpm workspaces + turbo. No new dependencies.
-
-## Global Constraints
-
-- Monorepo: `packages/protocol` (schemas), `packages/extension` (MV3), `packages/cli` (daemon + CLI). cli/extension consume protocol's `dist/` — **after any protocol change run `pnpm --filter @reins/protocol build` before building or testing cli/extension** or you test against stale schemas.
-- Existing error code for policy denials is `policy_denied` (class `PolicyDenied`, `packages/extension/src/lib/policy.ts`). Do NOT invent a new code.
-- Audit writes are best-effort: a full disk must never fail an RPC. Redaction happens before write; plaintext secrets never reach disk.
-- The repo's flag parser (`packages/cli/src/args.ts`) supports `--flag` forms only; the viewer's count flag is `--last <n>`.
-- Lint/format: `pnpm lint` (biome) must pass. Typecheck: `pnpm typecheck`.
-- Commit after every task. Write commit messages in normal prose, conventional-commit style, ending with `Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>`.
-- Run all commands from the repo root: `/Users/karn/code/karnstack/reins`.
-

-
-### Task 1: Protocol — `ResponseMeta` on `ResponseFrame`
-
-**Files:**
-- Modify: `packages/protocol/src/bridge.ts`
-- Test: `packages/protocol/src/bridge.test.ts`
-
-**Interfaces:**
-- Consumes: `Tier` from `packages/protocol/src/policy.ts` (already exported).
-- Produces: `ResponseMeta` zod schema + type `{ host?: string; tier?: Tier; tabId?: number }`; `ResponseFrame` gains optional `meta: ResponseMeta`. Both re-exported through `packages/protocol/src/index.ts` (it already does `export *` from bridge — verify, don't assume).
-
-- [ ] **Step 1: Write the failing test**
-
-Append to `packages/protocol/src/bridge.test.ts`:
-
-```ts
-describe("ResponseMeta", () => {
-  it("round-trips meta on a response frame", () => {
-    const frame = ResponseFrame.parse({
-      type: "response",
-      id: "r1",
-      ok: true,
-      result: { done: true },
-      meta: { host: "app.example.com", tier: "full", tabId: 412 },
-    });
-    expect(frame.meta).toEqual({ host: "app.example.com", tier: "full", tabId: 412 });
-  });
-
-  it("parses frames without meta (older extensions)", () => {
-    const frame = ResponseFrame.parse({ type: "response", id: "r2", ok: true, result: 1 });
-    expect(frame.meta).toBeUndefined();
-  });
-
-  it("allows partial meta (denial without tabId)", () => {
-    const frame = ResponseFrame.parse({
-      type: "response",
-      id: "r3",
-      ok: false,
-      error: { code: "policy_denied", message: "blocked" },
-      meta: { host: "bank.com", tier: "read" },
-    });
-    expect(frame.meta?.host).toBe("bank.com");
-    expect(frame.meta?.tabId).toBeUndefined();
-  });
-});
-```
-
-Add `ResponseFrame` (already imported) and `describe` to the test file's imports if missing.
-
-- [ ] **Step 2: Run test to verify it fails**
-
-Run: `pnpm --filter @reins/protocol test`
-Expected: FAIL — `meta` is stripped by zod (unknown key) so `frame.meta` is `undefined` in the first test.
-
-- [ ] **Step 3: Implement**
-
-In `packages/protocol/src/bridge.ts`, add after the `FrameError` block (import `Tier` at the top: `import { Tier } from "./policy.js";`):
-
-```ts
-/** Optional target metadata the extension stamps on a response: the
- *  resolved tab/host/tier the command actually hit. Consumed by the
- *  daemon's audit trail. Absent on daemon-side failures and on responses
- *  from extensions older than this field. */
-export const ResponseMeta = z.object({
-  host: z.string().optional(),
-  tier: Tier.optional(),
-  tabId: z.number().optional(),
-});
-export type ResponseMeta = z.infer<typeof ResponseMeta>;
-```
-
-In `ResponseFrame`, add the field:
-
-```ts
-export const ResponseFrame = z.object({
-  type: z.literal("response"),
-  id: z.string().min(1),
-  ok: z.boolean(),
-  result: z.unknown().optional(),
-  error: FrameError.optional(),
-  meta: ResponseMeta.optional(),
-});
-```
-
-Verify `packages/protocol/src/index.ts` re-exports bridge (`export * from "./bridge.js"` or named exports — if named, add `ResponseMeta`).
-
-- [ ] **Step 4: Run tests, typecheck, build**
-
-Run: `pnpm --filter @reins/protocol test && pnpm --filter @reins/protocol typecheck && pnpm --filter @reins/protocol build`
-Expected: PASS + clean build (the `dist/` rebuild is what downstream tasks consume).
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/protocol/src/bridge.ts packages/protocol/src/bridge.test.ts
-git commit -m "feat(protocol): optional ResponseMeta (host/tier/tabId) on ResponseFrame"
-```
-
----
-
-### Task 2: Extension — `ensureAllowed` returns the tier; `PolicyDenied` carries meta
-
-**Files:**
-- Modify: `packages/extension/src/lib/policy.ts`
-- Test: `packages/extension/src/lib/policy.test.ts`
-
-**Interfaces:**
-- Consumes: `ResponseMeta` from `@reins/protocol` (Task 1).
-- Produces: `ensureAllowed(method, host): Promise<Tier>` (was `Promise<void>`) — returns the effective tier when allowed; `PolicyDenied` gains a mutable `meta?: ResponseMeta` property, pre-filled with `{ host, tier }` at throw time.
-
-- [ ] **Step 1: Write the failing test**
-
-Append to `packages/extension/src/lib/policy.test.ts` (inside or alongside the existing `ensureAllowed` tests, reusing that file's storage-stub setup):
-
-```ts
-it("returns the effective tier when allowed", async () => {
-  // default policy is full everywhere
-  await expect(ensureAllowed("click", "app.example.com")).resolves.toBe("full");
-  await expect(ensureAllowed("read_text", "app.example.com")).resolves.toBe("full");
-});
-
-it("stamps meta on PolicyDenied", async () => {
-  await seedPolicy({ defaultTier: "full", rules: [{ pattern: "bank.com", tier: "read" }] });
-  const err = await ensureAllowed("click", "bank.com").catch((e) => e);
-  expect(err).toBeInstanceOf(PolicyDenied);
-  expect(err.code).toBe("policy_denied");
-  expect(err.meta).toEqual({ host: "bank.com", tier: "read" });
-});
-```
-
-Adapt `seedPolicy` to whatever helper the existing tests use to write policy into the chrome.storage stub (the file already tests `ensureAllowed` denials — copy its arrangement; do not invent a new stub).
-
-- [ ] **Step 2: Run test to verify it fails**
-
-Run: `pnpm --filter @reins/extension test -- policy.test`
-Expected: FAIL — `resolves.toBe("full")` gets `undefined`; `err.meta` is `undefined`.
-
-- [ ] **Step 3: Implement**
-
-In `packages/extension/src/lib/policy.ts`:
-
-```ts
-import type { ResponseMeta } from "@reins/protocol";
-
-/** Refused by the policy gate. `code` survives to the ResponseFrame. */
-export class PolicyDenied extends Error {
-  readonly code = "policy_denied";
-  /** Resolved target for the audit trail; the dispatch gate adds tabId. */
-  meta?: ResponseMeta;
-}
-```
-
-Replace `ensureAllowed`:
-
-```ts

-### Task 3: Extension — gate builds meta; `dispatchWithMeta`
-
-**Files:**
-- Modify: `packages/extension/src/lib/dispatch.ts`
-- Test: `packages/extension/src/lib/dispatch.test.ts`
-
-**Interfaces:**
-- Consumes: `ensureAllowed` returning `Tier`, `PolicyDenied.meta` (Task 2), `ResponseMeta` (Task 1).
-- Produces: `export interface DispatchOutcome { result: unknown; meta?: ResponseMeta }`; `export async function dispatchWithMeta(method: string, params: unknown): Promise<DispatchOutcome>`. Existing `dispatchMethod(method, params): Promise<unknown>` KEEPS its signature (thin wrapper returning `.result`) so the many existing dispatch tests stay valid.
-
-- [ ] **Step 1: Write the failing test**
-
-Append to `packages/extension/src/lib/dispatch.test.ts`, reusing the file's existing chrome/tab/policy stubs (it already fakes `chrome.tabs.get`, `resolveTabId` targets, and policy storage — follow the arrangement of the existing gate tests):
-
-```ts
-describe("dispatchWithMeta", () => {
-  it("stamps host/tier/tabId on success", async () => {
-    // arrange: one tab { id: 7, url: "https://app.example.com/x" }, default policy full
-    const out = await dispatchWithMeta("read_text", { tabId: 7 });
-    expect(out.meta).toEqual({ host: "app.example.com", tier: "full", tabId: 7 });
-  });
-
-  it("stamps meta (with tabId) on a policy denial", async () => {
-    // arrange: tab { id: 7, url: "https://bank.com/x" }, rule bank.com → read
-    const err = await dispatchWithMeta("click", { tabId: 7 }).catch((e) => e);
-    expect(err.code).toBe("policy_denied");
-    expect(err.meta).toEqual({ host: "bank.com", tier: "read", tabId: 7 });
-  });
-
-  it("leaves meta undefined for policy_get", async () => {
-    const out = await dispatchWithMeta("policy_get", {});
-    expect(out.meta).toBeUndefined();
-  });
-
-  it("dispatchMethod still returns the bare result", async () => {
-    const result = await dispatchMethod("read_text", { tabId: 7 });
-    expect(result).not.toHaveProperty("meta");
-  });
-});
-```
-
-- [ ] **Step 2: Run test to verify it fails**
-
-Run: `pnpm --filter @reins/extension test -- dispatch.test`
-Expected: FAIL — `dispatchWithMeta` is not exported.
-
-- [ ] **Step 3: Implement**
-
-In `packages/extension/src/lib/dispatch.ts`:
-
-1. Import `PolicyDenied` alongside the existing policy imports, and `type ResponseMeta` from `@reins/protocol`.
-2. Change `gate` to return params + meta, and to add `tabId` to a denial's meta:
-
-```ts
-interface Gated {
-  params: Record<string, unknown>;
-  meta: ResponseMeta;
-}
-
-async function gate(method: GatedMethod, params: unknown): Promise<Gated> {
-  const p = { ...((params ?? {}) as Record<string, unknown>) };
-  if (method === "list_tabs") return { params: p, meta: {} };
-  if (method === "open_tab") {
-    const host = hostOf(String(p.url ?? ""));
-    const tier = await ensureAllowed("open_tab", host);
-    return { params: p, meta: { host, tier } };
-  }
-  const tabId = await resolveTabId(typeof p.tabId === "number" ? p.tabId : undefined);
-  try {
-    const tab = await chrome.tabs.get(tabId);
-    const host = hostOf(tab.url ?? "");
-    const tier = await ensureAllowed(method, host);
-    if (method === "navigate") {
-      const to = String(p.to ?? "");
-      if (!NAV_HISTORY.has(to)) {
-        let dest = hostOf(to);
-        if (dest === undefined) {
-          // Protocol-relative ("//bank.com/x") and path-relative targets
-          // resolve against the current page — check what they resolve to,
-          // or they would dodge the destination gate.
-          try {
-            dest = hostOf(new URL(to, tab.url).href);
-          } catch {
-            // unresolvable target — the handler will reject it
-          }
-        }
-        if (dest !== undefined) await ensureAllowed("navigate", dest);
-      }
-    }
-    return { params: { ...p, tabId }, meta: { host, tier, tabId } };
-  } catch (err) {
-    // A denial thrown in here knows host+tier but not the tab — add it.
-    if (err instanceof PolicyDenied && err.meta) err.meta = { ...err.meta, tabId };
-    throw err;
-  }
-}
-```
-
-3. Rename the exported entry point and wrap:
-
-```ts
-export interface DispatchOutcome {
-  result: unknown;
-  meta?: ResponseMeta;
-}
-
-/** Route a bridge method to its handler; the outcome carries the resolved
- *  target (host/tier/tabId) for the daemon's audit trail. */
-export async function dispatchWithMeta(method: string, params: unknown): Promise<DispatchOutcome> {
-  if (method === "policy_get") return { result: await policy() };
-  if (method === "policy_tighten") {
-    const { pattern, tier } = PolicyTightenParams.parse(params ?? {});
-    return { result: await tightenPolicy(pattern, tier) };
-  }
-  if (!(method in METHOD_TIERS)) throw new Error(`unknown method: ${method}`);
-  const gated = await gate(method as GatedMethod, params);
-  const result = await runHandler(method as GatedMethod, gated.params);
-  return { result, meta: gated.meta };
-}
-
-export async function dispatchMethod(method: string, params: unknown): Promise<unknown> {
-  return (await dispatchWithMeta(method, params)).result;
-}
-```
-
-4. Move the existing `switch (method)` body into a private `runHandler(method: GatedMethod, gated: Record<string, unknown>): Promise<unknown>` — the cases are unchanged, each `case` now reads the `gated` parameter (was the `gated` local). `list_tabs`'s redaction logic moves with it.
-
-- [ ] **Step 4: Run tests to verify they pass**
-
-Run: `pnpm --filter @reins/extension test -- dispatch.test`
-Expected: PASS — new describe block AND all pre-existing dispatch tests (they call `dispatchMethod`, whose behavior is unchanged).
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/extension/src/lib/dispatch.ts packages/extension/src/lib/dispatch.test.ts
-git commit -m "feat(extension): dispatchWithMeta stamps resolved host/tier/tabId"

-### Task 4: Extension — meta over the wire (bridge-client, background, offscreen)
-
-**Files:**
-- Modify: `packages/extension/src/lib/bridge-client.ts`
-- Modify: `packages/extension/src/background.ts`
-- Modify: `packages/extension/src/offscreen.ts`
-- Test: `packages/extension/src/lib/bridge-client.test.ts`
-
-**Interfaces:**
-- Consumes: `DispatchOutcome` shape (Task 3).
-- Produces: `bridge-client.ts`'s `Dispatch` type becomes `(method, params) => Promise<DispatchOutcome>` where `export interface DispatchOutcome { result: unknown; meta?: unknown }` (kept `unknown` — this file is transport-agnostic and imports nothing from protocol). Response frames sent to the daemon include `meta` when present, on success AND error paths.
-
-- [ ] **Step 1: Write the failing test**
-
-In `packages/extension/src/lib/bridge-client.test.ts`, the existing tests stub `dispatch` — they must change from `dispatch: async () => value` to `dispatch: async () => ({ result: value })`. First add the new behavior tests (reuse the file's fake-socket helper):
-
-```ts
-it("forwards dispatch meta on the response frame", async () => {
-  // dispatch resolves { result, meta }
-  const client = makeConnectedClient({
-    dispatch: async () => ({
-      result: { ok: true },
-      meta: { host: "app.example.com", tier: "full", tabId: 7 },
-    }),
-  });
-  sendRequestFrame(client, { id: "r1", method: "read_text", params: {} });
-  const frame = await nextSentFrame();
-  expect(frame).toMatchObject({
-    type: "response", id: "r1", ok: true,
-    meta: { host: "app.example.com", tier: "full", tabId: 7 },
-  });
-});
-
-it("forwards meta from a thrown dispatch error", async () => {
-  const err = new Error("blocked by policy: bank.com is read-only") as Error & {
-    code?: string; meta?: unknown;
-  };
-  err.code = "policy_denied";
-  err.meta = { host: "bank.com", tier: "read", tabId: 7 };
-  const client = makeConnectedClient({ dispatch: async () => { throw err; } });
-  sendRequestFrame(client, { id: "r2", method: "click", params: {} });
-  const frame = await nextSentFrame();
-  expect(frame).toMatchObject({
-    type: "response", id: "r2", ok: false,
-    error: { code: "policy_denied" },
-    meta: { host: "bank.com", tier: "read", tabId: 7 },
-  });
-});
-
-it("omits meta when dispatch returns none", async () => {
-  const client = makeConnectedClient({ dispatch: async () => ({ result: 1 }) });
-  sendRequestFrame(client, { id: "r3", method: "policy_get", params: {} });
-  const frame = await nextSentFrame();
-  expect(frame).not.toHaveProperty("meta");
-});
-```
-
-`makeConnectedClient` / `sendRequestFrame` / `nextSentFrame` stand for whatever the existing tests use to drive a client over the fake socket — mirror them exactly.
-
-- [ ] **Step 2: Run test to verify it fails**
-
-Run: `pnpm --filter @reins/extension test -- bridge-client.test`
-Expected: FAIL — new tests fail (no meta on frames); pre-existing tests may also fail typecheck once the Dispatch type changes (fixed in step 3).
-
-- [ ] **Step 3: Implement**
-
-`packages/extension/src/lib/bridge-client.ts`:
-
-```ts
-export interface DispatchOutcome {
-  result: unknown;
-  /** Resolved action target (host/tier/tabId), forwarded verbatim to the daemon. */
-  meta?: unknown;
-}
-export type Dispatch = (method: string, params: unknown) => Promise<DispatchOutcome>;
-```
-
-Rework `#handleRequest`:
-
-```ts
-async #handleRequest(id: string, method: string, params: unknown): Promise<void> {
-  const socket = this.#socket;
-  if (!socket) return;
-  let outcome: DispatchOutcome | undefined;
-  let dispatchError: unknown;
-  let threw = false;
-  try {
-    outcome = await this.#opts.dispatch(method, params);
-  } catch (err) {
-    threw = true;
-    dispatchError = err;
-  }
-  if (this.#socket !== socket) return; // socket replaced/closed during dispatch
-  try {
-    if (!threw && outcome) {
-      socket.send(
-        JSON.stringify({
-          type: "response",
-          id,
-          ok: true,
-          result: outcome.result,
-          ...(outcome.meta !== undefined ? { meta: outcome.meta } : {}),
-        }),
-      );
-    } else {
-      const message =
-        dispatchError instanceof Error ? dispatchError.message : String(dispatchError);
-      const code =
-        typeof (dispatchError as { code?: unknown })?.code === "string"
-          ? (dispatchError as { code: string }).code
-          : "HANDLER_ERROR";
-      const meta = (dispatchError as { meta?: unknown })?.meta;
-      socket.send(
-        JSON.stringify({
-          type: "response",
-          id,
-          ok: false,
-          error: { code, message },
-          ...(meta !== undefined ? { meta } : {}),
-        }),
-      );
-    }
-  } catch {
-    // Socket closed between dispatch and send; response cannot be delivered.
-  }
-}
-```
-
-Update every pre-existing `dispatch:` stub in `bridge-client.test.ts` from `async () => X` to `async () => ({ result: X })` (mechanical; assertions on `result` unchanged).
-
-`packages/extension/src/background.ts` — the `reins:dispatch` case switches to `dispatchWithMeta` and relays meta both ways:
-
-```ts
-case "reins:dispatch": {
-  const method = message.method as string;
-  const params = message.params;
-  dispatchWithMeta(method, params)
-    .then(({ result, meta }) => sendResponse({ result, ...(meta !== undefined ? { meta } : {}) }))
-    .catch((err) =>
-      sendResponse({
-        error: err instanceof Error ? err.message : String(err),
-        code:
-          typeof (err as { code?: unknown })?.code === "string"
-            ? (err as { code: string }).code
-            : undefined,
-        meta: (err as { meta?: unknown })?.meta,
-      }),
-    );
-  return true;
-}
-```
-
-Update the import: `import { dispatchWithMeta } from "./lib/dispatch.js";` (drop `dispatchMethod` if now unused there).
-
-`packages/extension/src/offscreen.ts` — relay meta through `offscreenDispatch`:
-
-```ts
-import type { DispatchOutcome } from "./lib/bridge-client.js";
-
-async function offscreenDispatch(method: string, params: unknown): Promise<DispatchOutcome> {
-  const res = (await chrome.runtime.sendMessage({ type: "reins:dispatch", method, params })) as
-    | { result: unknown; meta?: unknown; error?: undefined; code?: undefined }
-    | { error: string; code?: string; meta?: unknown; result?: undefined }
-    | undefined;
-  if (res?.error) {
-    const err = new Error(res.error) as Error & { code?: string; meta?: unknown };
-    if (res.code) err.code = res.code;
-    if (res.meta !== undefined) err.meta = res.meta;
-    throw err;
-  }
-  return { result: res?.result, meta: res?.meta };
-}
-```

-### Task 6: CLI — `BridgeHost.requestFull` (meta + browserId + error code out of the bridge)
-
-**Files:**
-- Modify: `packages/cli/src/bridge.ts`
-- Test: `packages/cli/src/bridge.test.ts`
-
-**Interfaces:**
-- Consumes: `ResponseMeta` from `@reins/protocol` (Task 1 — protocol must be rebuilt).
-- Produces:
-  - `export interface BridgeReply { result: unknown; meta?: ResponseMeta; browserId: string }`
-  - `BridgePort` gains `requestFull(method, params, opts?): Promise<BridgeReply>`; `request` keeps its `Promise<unknown>` signature (now delegates).
-  - Rejections carry `code?: string` and `meta?: ResponseMeta` properties on the Error when the response frame had them.
-
-- [ ] **Step 1: Write the failing test**
-
-Append to `packages/cli/src/bridge.test.ts`, reusing its existing fake-extension WebSocket harness (the file already connects a `ws` client and answers request frames — mirror that arrangement):
-
-```ts
-describe("requestFull", () => {
-  it("resolves result + meta + browserId", async () => {
-    // fake extension answers with meta
-    respondWith((frame) => ({
-      type: "response", id: frame.id, ok: true, result: { done: true },
-      meta: { host: "app.example.com", tier: "full", tabId: 7 },
-    }));
-    const reply = await host.requestFull("read_text", {});
-    expect(reply.result).toEqual({ done: true });
-    expect(reply.meta).toEqual({ host: "app.example.com", tier: "full", tabId: 7 });
-    expect(reply.browserId).toBe("b1");
-  });
-
-  it("rejects with code and meta from an error frame", async () => {
-    respondWith((frame) => ({
-      type: "response", id: frame.id, ok: false,
-      error: { code: "policy_denied", message: "blocked by policy: bank.com is read-only" },
-      meta: { host: "bank.com", tier: "read", tabId: 7 },
-    }));
-    const err = await host.requestFull("click", {}).catch((e) => e);
-    expect(err.message).toBe("policy_denied: blocked by policy: bank.com is read-only");
-    expect(err.code).toBe("policy_denied");
-    expect(err.meta).toEqual({ host: "bank.com", tier: "read", tabId: 7 });
-  });
-
-  it("request() still resolves the bare result", async () => {
-    respondWith((frame) => ({ type: "response", id: frame.id, ok: true, result: 42 }));
-    await expect(host.request("read_text", {})).resolves.toBe(42);
-  });
-});
-```
-
-- [ ] **Step 2: Run test to verify it fails**
-
-Run: `pnpm --filter @reins/protocol build && pnpm --filter @karnstack/reins test -- bridge.test`
-Expected: FAIL — `requestFull` does not exist.
-
-- [ ] **Step 3: Implement**
-
-In `packages/cli/src/bridge.ts`:
-
-```ts
-import type { ResponseMeta } from "@reins/protocol"; // add to the existing protocol import
-
-/** A settled bridge request: the result plus the extension-stamped action
- *  target and the browser that served it — everything the audit trail needs. */
-export interface BridgeReply {
-  result: unknown;
-  meta?: ResponseMeta;
-  browserId: string;
-}
-
-export interface BridgePort {
-  readonly paired: boolean;
-  readonly browsers: BrowserInfo[];
-  request(method: string, params: unknown, opts?: RequestOpts): Promise<unknown>;
-  requestFull(method: string, params: unknown, opts?: RequestOpts): Promise<BridgeReply>;
-}
-```
-
-`Pending.resolve` becomes `(value: BridgeReply) => void`. `#settle` becomes:
-
-```ts
-#settle(id: string, frame: ResponseFrame): void {
-  const pending = this.#pending.get(id);
-  if (!pending) return;
-  clearTimeout(pending.timer);
-  this.#pending.delete(id);
-  if (frame.ok === true) {
-    pending.resolve({ result: frame.result, meta: frame.meta, browserId: pending.browserId });
-  } else {
-    const err = frame.error ?? { code: "ERR", message: "request failed" };
-    const e = new Error(`${err.code}: ${err.message}`) as Error & {
-      code?: string;
-      meta?: ResponseMeta;
-    };
-    e.code = err.code;
-    e.meta = frame.meta;
-    pending.reject(e);
-  }
-}
-```
-
-Rename the existing `request` body to `requestFull` (its Promise generic becomes `BridgeReply`; the timeout/rejection paths are unchanged), then:
-
-```ts
-request(method: string, params: unknown, opts: RequestOpts = {}): Promise<unknown> {
-  return this.requestFull(method, params, opts).then((r) => r.result);
-}
-```
-
-- [ ] **Step 4: Run the cli suite + typecheck**
-
-Run: `pnpm --filter @karnstack/reins test -- bridge.test && pnpm --filter @karnstack/reins typecheck`
-Expected: PASS. (Typecheck also confirms every `BridgePort` implementer — test stand-ins included — gained `requestFull`; add a delegating stub where the compiler points.)
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/cli/src/bridge.ts packages/cli/src/bridge.test.ts
-git commit -m "feat(cli): BridgeHost.requestFull exposes meta, browserId, error code"

-

-
-And append an end-to-end check to `packages/cli/src/integration.test.ts` (reuse `setupHarness`/`standInExtension`; pass an in-memory audit hook into `startDaemon` — extend `setupHarness` to accept and forward `audit`):

-
-(`respondNext` stands for however the stand-in extension answers request frames in this file — follow the existing pattern; if it always echoes a fixed response, add the meta variant beside it.)
-

-### Task 9: Docs, changeset, roadmap tick
-
-**Files:**
-- Modify: `packages/web/src/routes/docs/security.tsx`
-- Create: `.changeset/audit-log.md`
-- Modify: `docs/ROADMAP.md`
-
-**Interfaces:** none (docs only).
-
-- [ ] **Step 1: Web docs — audit section**
-
-In `packages/web/src/routes/docs/security.tsx`, insert after the "Per-site permissions" section (before `<h2>Data handling</h2>`):
-
-```tsx
-<h2>Audit trail</h2>
-<ul>
-  <li>
-    Every command the daemon executes — and every one the policy blocks — appends one
-    structured line (timestamp, command, browser, tab, host, tier, outcome, duration) to{" "}
-    <code>~/.reins/logs/audit-YYYY-MM-DD.jsonl</code>. <code>reins audit</code> renders the
-    trail; <code>--denied</code> shows only what policy blocked.
-  </li>
-  <li>
-    Value-bearing params — typed text, fill values, <code>eval</code> code, CDP payloads —
-    are redacted before the line is written, so the trail never stores what the agent typed,
-    only that it typed.
-  </li>
-  <li>Audit files are pruned after 30 days. Writes are best-effort: a full disk never blocks a command.</li>
-</ul>
-```
-
-Run: `pnpm --filter @reins/web typecheck`
-Expected: clean.
-
-- [ ] **Step 2: Changeset**
-
-Create `.changeset/audit-log.md`:
-
-```md
----
-"@karnstack/reins": minor
-"@reins/extension": minor
----
-
-`reins audit` — a per-action audit trail. The extension stamps each response with the resolved host, permission tier, and tab; the daemon writes one redacted JSONL line per action (policy denials included) to `~/.reins/logs/audit-YYYY-MM-DD.jsonl`, pruned after 30 days. Value-bearing params (typed text, fill values, eval code, CDP payloads) are redacted before anything reaches disk.
-```
-
-- [ ] **Step 3: Roadmap tick**
-
-In `docs/ROADMAP.md`, change the audit-log bullet from `⬜` to `✅` and rewrite to past tense:
-
-```md
-- ✅ **Audit log.** Shipped: one structured JSONL line per action (and per
-  policy denial) in `~/.reins/logs/audit-YYYY-MM-DD.jsonl`, value-bearing
-  params redacted before write, 30-day retention, `reins audit` to view
-  (`--last`, `--denied`, `--json`).
-```
-
-- [ ] **Step 4: Full verification**
-
-Run: `pnpm lint && pnpm typecheck && pnpm build && pnpm test`
-Expected: all green across the workspace.
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/web/src/routes/docs/security.tsx .changeset/audit-log.md docs/ROADMAP.md
-git commit -m "docs: audit trail on security page, changeset, roadmap tick"

-## Post-plan notes for the executor
-
-- Tasks 2–4 (extension) and 5 (cli audit.ts) are independent of each other; 6–8 depend on 1 and 5. Task order as written is safe sequentially.
-- If any pre-existing test asserts the exact shape of response frames or the `Dispatch` type, the fix is always the mechanical `{ result: X }` wrap — never weaken an assertion to pass.
-- Manual end-to-end check (optional, needs the sideloaded extension; see memory note "sideload bundle order"): rebuild extension → cli bundle → reload the reins extension, run `reins tabs && reins text`, then `reins audit` — expect two lines with real hosts.

-# Permission Model Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Per-host permission tiers (`deny` < `read` < `full`) enforced inside the extension, with popup-only grants and a tighten-only `reins policy` CLI.
-
-**Architecture:** Policy (default tier + host/wildcard rules) lives in `chrome.storage.local`; a gate in the extension's `dispatchMethod` resolves the target tab's host and refuses methods above the host's tier. Two new bridge methods (`policy_get`, `policy_tighten`) pass through the daemon untouched. The shared tier/matcher code lives in `@reins/protocol`.
-
-**Tech Stack:** TypeScript, zod v4, vitest, pnpm workspace (packages: `protocol`, `extension`, `cli`). Extension is MV3 (service worker + offscreen doc).
-
-**Spec:** `docs/superpowers/specs/2026-07-11-permission-model-design.md` — the authority on behavior.
-
-## Global Constraints
-
-- Shipped default policy: `{ defaultTier: "full", rules: [] }` (today's behavior).
-- Grants (loosening) happen ONLY via the popup writing storage directly. `policy_tighten` must reject any non-strictly-tightening change.
-- Matching precedence: exact host > longest matching wildcard > `defaultTier`. `*.foo.com` matches apex `foo.com` AND subdomains.
-- Non-http(s) or unparseable tab URLs → `defaultTier`.
-- Denied tabs in `list_tabs` are REDACTED (tabId + active kept, `title: ""`, `url: ""`, `blocked: true`), not omitted.
-- Policy error text always names the host, its tier, and the popup remediation. Error `code` is `"policy_denied"` end-to-end (ResponseFrame `error.code`).
-- After ANY change to `packages/protocol`, run `pnpm --filter @reins/protocol build` before running cli/extension tests (workspace imports resolve to `dist/`).
-- Run tests per package: `pnpm --filter @karnstack/reins test`, `pnpm --filter @reins/extension test`, `pnpm --filter @reins/protocol test`. Typecheck: `pnpm -r typecheck`.
-- Commit style: Conventional Commits, subject ≤ 50 chars, no AI attribution in body (trailer only).

-
-**Files:**
-- Create: `packages/protocol/src/policy.ts`

-- Modify: `packages/protocol/src/bridge.ts` (add `blocked` to `Tab`)

-### Task 3: extension — dispatch gate, policy methods, redaction, error code
-
-**Files:**
-- Modify: `packages/extension/src/lib/dispatch.ts`
-- Modify: `packages/extension/src/lib/dispatch.test.ts`
-- Modify: `packages/extension/src/background.ts` (thread `code` through `reins:dispatch`)
-- Modify: `packages/extension/src/offscreen.ts` (rehydrate `code` onto the thrown Error)
-- Modify: `packages/extension/src/lib/bridge-client.ts` (use `err.code` in ResponseFrame)
-- Modify: `packages/extension/src/lib/bridge-client.test.ts` (assert code passthrough)
-
-**Interfaces:**
-- Consumes (Tasks 1–2): `METHOD_TIERS`, `GatedMethod`, `hostOf`, `effectiveTier`, `PolicyTightenParams` from `@reins/protocol`; `ensureAllowed`, `policy`, `tightenPolicy` from `./policy.js`; `resolveTabId` from `./cdp.js` (existing, exported).
-- Produces: `dispatchMethod` now also handles `"policy_get"` and `"policy_tighten"`; every gated method receives params with `tabId` pinned to the resolved tab; errors reaching the daemon carry `error.code === "policy_denied"` when the gate refused.
-
-- [ ] **Step 1: Extend dispatch tests (failing)**
-
-In `packages/extension/src/lib/dispatch.test.ts`:
-
-1. Extend the `./cdp.js` mock with `resolveTabId` (the gate imports it):
-
-```ts
-vi.mock("./cdp.js", () => ({
-  resolveTabId: vi.fn(async (tabId?: number) => tabId ?? 1),
-  cdpNavigate: vi.fn(async () => ({ url: "https://x/" })),
-  cdpSnapshot: vi.fn(async () => ({ content: "", refs: [] })),
-  cdpClick: vi.fn(async () => ({ ok: true })),
-  cdpType: vi.fn(async () => ({ ok: true })),
-  cdpScreenshot: vi.fn(async () => ({ data: "abc123", mimeType: "image/png" })),
-  cdpEval: vi.fn(async () => ({ value: 42 })),
-  cdpWaitFor: vi.fn(async () => ({ ok: true })),
-}));
-```
-
-2. Mock `./policy.js` so existing routing tests keep passing (allow-all), and
-   capture calls:
-
-```ts
-vi.mock("./policy.js", async (importOriginal) => {
-  const real = await importOriginal<typeof import("./policy.js")>();
-  return {
-    ...real,
-    policy: vi.fn(async () => ({ defaultTier: "full", rules: [] })),
-    ensureAllowed: vi.fn(async () => undefined),
-    tightenPolicy: vi.fn(async (pattern: string, tier: string) => ({
-      defaultTier: "full",
-      rules: [{ pattern, tier }],
-    })),
-  };
-});
-```
-
-Import the mocks at the top of the file:
-
-```ts
-import { ensureAllowed, PolicyDenied, policy, tightenPolicy } from "./policy.js";
-```
-
-3. Existing routing tests that hit tab-scoped methods now need a `chrome`
-   stub with `tabs.get` (the gate resolves the host). Add a helper and use it
-   in the `routes navigate/click/...` tests:
-
-```ts
-function stubTabs(url = "https://x.com/") {
-  vi.stubGlobal("chrome", {
-    tabs: {
-      get: async (id: number) => ({ id, url }),
-      query: async () => [{ id: 1, title: "t", url, active: true }],
-      create: async () => ({ id: 11 }),
-      remove: async () => undefined,
-      update: async () => ({}),
-    },
-    windows: { update: async () => ({}) },
-  });
-}
-```
-
-Call `stubTabs()` at the start of each routing test that previously ran
-without a chrome stub (the CDP/page-actions/monitor routing tests), and keep
-per-test overrides where the test already installs its own stub — merging
-`tabs.get` into those (`close_tab`, `select_tab`, `resize`, `open_tab`
-gains nothing: it is destination-checked, not tab-resolved).
-
-4. New test blocks:
-
-```ts
-describe("policy gate", () => {
-  it("checks the resolved tab's host for tab-scoped methods", async () => {
-    stubTabs("https://app.example.com/page");
-    await dispatchMethod("click", { ref: "e1" });

-    expect(ensureAllowed).toHaveBeenCalledWith("navigate", "here.com");
-  });
-
-  it("propagates PolicyDenied from the gate", async () => {

-    vi.mocked(ensureAllowed).mockRejectedValueOnce(
-      new PolicyDenied("blocked by policy: x.com is read-only"),
-    );
-    await expect(dispatchMethod("click", { ref: "e1" })).rejects.toThrow(/blocked by policy/);
-  });
-});
-
-describe("list_tabs redaction", () => {
-  it("redacts denied tabs, passes others through", async () => {
-    vi.stubGlobal("chrome", {

-    vi.mocked(policy).mockResolvedValueOnce({
-      defaultTier: "full",
-      rules: [{ pattern: "*.bank.com", tier: "deny" }],
-    });
-    expect(await dispatchMethod("list_tabs", {})).toEqual({
-      tabs: [

-        { tabId: 2, title: "Docs", url: "https://docs.example.com", active: false },
-      ],
-    });
-  });
-});
-
-describe("policy methods", () => {
-  it("policy_get returns the policy", async () => {
-    expect(await dispatchMethod("policy_get", {})).toEqual({
-      defaultTier: "full",

-    await expect(

-  });
-});
-```
-
-- [ ] **Step 2: Run tests to verify the new ones fail**
-
-Run: `pnpm --filter @reins/extension test -- dispatch`
-Expected: new tests FAIL (`ensureAllowed` never called, `policy_get` hits
-"unknown method"); pre-existing routing tests may also fail until Step 3.
-
-- [ ] **Step 3: Implement the gate in `dispatch.ts`**
-
-Replace the imports/top of `packages/extension/src/lib/dispatch.ts` and wrap

-  }
-}
-```
-
-(The `default` branch is now unreachable for real methods — kept as a
-safety net. Every `case` body changes `params` → `gated`; nothing else.)
-
-- [ ] **Step 4: Thread the error code across the offscreen relay**
-
-`packages/extension/src/background.ts`, in the `reins:dispatch` case:
-
-```ts
-case "reins:dispatch": {
-  const method = message.method as string;
-  const params = message.params;
-  dispatchMethod(method, params)
-    .then((result) => sendResponse({ result }))
-    .catch((err) =>
-      sendResponse({
-        error: err instanceof Error ? err.message : String(err),
-        code: typeof (err as { code?: unknown })?.code === "string"
-          ? (err as { code: string }).code
-          : undefined,
-      }),
-    );
-  return true;
-}
-```
-
-`packages/extension/src/offscreen.ts`, `offscreenDispatch`:
-
-```ts
-async function offscreenDispatch(method: string, params: unknown): Promise<unknown> {
-  const res = (await chrome.runtime.sendMessage({ type: "reins:dispatch", method, params })) as
-    | { result: unknown; error?: undefined; code?: undefined }
-    | { error: string; code?: string; result?: undefined }
-    | undefined;
-  if (res?.error) {
-    const err = new Error(res.error) as Error & { code?: string };
-    if (res.code) err.code = res.code;
-    throw err;
-  }
-  return res?.result;
-}
-```
-
-`packages/extension/src/lib/bridge-client.ts`, in `#handleRequest`'s error
-branch:
-
-```ts
-const code =
-  typeof (dispatchError as { code?: unknown })?.code === "string"
-    ? ((dispatchError as { code: string }).code)
-    : "HANDLER_ERROR";
-socket.send(
-  JSON.stringify({ type: "response", id, ok: false, error: { code, message } }),
-);
-```
-
-Add to `packages/extension/src/lib/bridge-client.test.ts` (inside the
-existing describe, following the file's established harness pattern for a
-connected client — reuse its helpers):
-
-```ts
-it("uses err.code in the error frame when present", async () => {
-  // dispatch throws an Error carrying code "policy_denied"
-  // assert the sent response frame is
-  // { type: "response", id, ok: false, error: { code: "policy_denied", message: "nope" } }
-});
-```
-
-Implement the body with the file's existing fake-socket helpers (the test
-above `sends HANDLER_ERROR responses` is the template: copy it, make the
-dispatch mock throw `Object.assign(new Error("nope"), { code: "policy_denied" })`,
-and assert `error.code === "policy_denied"`).
-
-- [ ] **Step 5: Run tests to verify they pass**
-
-Run: `pnpm --filter @reins/extension test && pnpm --filter @reins/extension typecheck`
-Expected: PASS (all dispatch + bridge-client + policy + existing tests)

-- Consumes (Tasks 1–2): `DEFAULT_POLICY`, `Policy`, `Tier`, `effectiveTier`, `hostOf`, `normalizePattern` from `@reins/protocol`; `POLICY_KEY` from `./lib/policy.js`.
-- Produces: pure helpers in `policy-view.ts` (tested); popup wiring (untested, minimal):
-  - `upsertRule(p: Policy, pattern: string, tier: Tier): Policy`
-  - `removeRule(p: Policy, pattern: string): Policy`
-  - `setDefaultTier(p: Policy, tier: Tier): Policy`
-
-The popup is the ONLY loosening surface — it writes `chrome.storage.local`
-directly (a user gesture). No tighten-only restriction here.
-
-- [ ] **Step 1: Write the failing test**
-
-Create `packages/extension/src/lib/policy-view.test.ts`:
-
-```ts
-import { describe, expect, it } from "vitest";
-import type { Policy } from "@reins/protocol";
-import { removeRule, setDefaultTier, upsertRule } from "./policy-view.js";
-
-const base: Policy = { defaultTier: "full", rules: [{ pattern: "x.com", tier: "read" }] };
-
-describe("upsertRule", () => {
-  it("adds a normalized rule", () => {
-    const next = upsertRule(base, "*.New.com", "deny");
-    expect(next.rules).toContainEqual({ pattern: "*.new.com", tier: "deny" });
-  });
-  it("replaces an existing rule (either direction — popup may loosen)", () => {
-    expect(upsertRule(base, "x.com", "full").rules).toEqual([
-      { pattern: "x.com", tier: "full" },
-    ]);
-  });
-  it("does not mutate the input", () => {
-    upsertRule(base, "y.com", "deny");
-    expect(base.rules).toHaveLength(1);
-  });
-});
-
-describe("removeRule", () => {
-  it("removes by pattern", () => {
-    expect(removeRule(base, "x.com").rules).toEqual([]);
-  });
-});
-
-describe("setDefaultTier", () => {
-  it("replaces defaultTier only", () => {
-    expect(setDefaultTier(base, "read")).toEqual({ ...base, defaultTier: "read" });
-  });
-});
-```
-
-- [ ] **Step 2: Run test to verify it fails**
-
-Run: `pnpm --filter @reins/extension test -- policy-view`
-Expected: FAIL — `Cannot find module './policy-view.js'`
-
-- [ ] **Step 3: Implement helpers**
-
-Create `packages/extension/src/lib/policy-view.ts`:
-
-```ts
-import { normalizePattern, type Policy, type Tier } from "@reins/protocol";
-
-/** Set `pattern` to `tier`, replacing any existing rule. Popup-only surface:
- *  this may loosen — the user's click in the popup IS the grant gesture. */
-export function upsertRule(p: Policy, patternInput: string, tier: Tier): Policy {
-  const pattern = normalizePattern(patternInput);
-  const rest = p.rules.filter((r) => r.pattern !== pattern);
-  return { ...p, rules: [...rest, { pattern, tier }] };
-}
-
-export function removeRule(p: Policy, pattern: string): Policy {
-  return { ...p, rules: p.rules.filter((r) => r.pattern !== pattern) };
-}
-
-export function setDefaultTier(p: Policy, tier: Tier): Policy {
-  return { ...p, defaultTier: tier };
-}
-```
-
-- [ ] **Step 4: Run test to verify it passes**
-
-Run: `pnpm --filter @reins/extension test -- policy-view`
-Expected: PASS
-
-- [ ] **Step 5: Add the popup section**
-
-In `packages/extension/src/popup.html`, insert between the Disconnect button
-and the `<details class="reins__advanced">` block:
-
-```html

-Run: `pnpm --filter @reins/extension build && pnpm --filter @reins/extension typecheck`
-Expected: vite build succeeds.
-
-Manual check (deferred to the branch-level verify pass if no browser at
-hand): load the unpacked build, open the popup on a normal site — host row
-shows, tier toggles persist across popup reopen, add/remove rules works,
-default selector persists.

-### Task 5: CLI — `reins policy` (view + tighten only)
-
-**Files:**
-- Create: `packages/cli/src/policy-cli.ts`
-- Create: `packages/cli/src/policy-cli.test.ts`
-- Modify: `packages/cli/src/cli.ts` (add `policy` case; export nothing new)
-- Modify: `packages/cli/src/cli-commands.ts` (help text: add `policy` under Management)
-
-**Interfaces:**
-- Consumes: `Policy`, `Tab`, `effectiveTier`, `hostOf` from `@reins/protocol`; `UsageError` from `./args.js`.
-- Produces:
-  - `policyText(policy: Policy, tabs: Tab[]): string`
-  - `runPolicy(argv: string[], deps: { rpc(method: string, params: Record<string, unknown>): Promise<unknown> }): Promise<string>` — returns the line(s) to print; throws `UsageError`/`Error` otherwise.
-  - cli.ts wires `deps.rpc` to the existing `ensureDaemon` + local `rpc` helper.
-
-Subcommands: `reins policy` (show), `reins policy deny <pattern>`,
-`reins policy readonly <pattern>`, `reins policy allow <pattern>` (always an
-error explaining popup grants). Optional `--browser <id>` on all.

-### Task 6: integration test — policy flows over the real bridge
-
-**Files:**
-- Modify: `packages/cli/src/integration.test.ts`
-
-**Interfaces:**
-- Consumes: existing harness (`setupHarness`, `standInExtension`, `rpc`). The stand-in extension is a lookup table today; it gains two entries and one error case.
-
-- [ ] **Step 1: Extend the stand-in + add failing tests**
-
-In `packages/cli/src/integration.test.ts`:
-
-1. Add to `METHOD_RESULTS`:
-
-```ts
-policy_get: { defaultTier: "full", rules: [] },
-policy_tighten: {
-  defaultTier: "full",
-  rules: [{ pattern: "evil.com", tier: "deny" }],
-},
-```
-
-2. Teach the stand-in to return an error frame for a magic marker (mirrors
-   the real extension refusing a gated method). Replace the `request`
-   branch of `standInExtension`:
-
-```ts
-if (msg.type === "request") {
-  if (msg.method === "click" && DENY_CLICKS) {
-    ws.send(
-      JSON.stringify({
-        type: "response",
-        id: msg.id,
-        ok: false,
-        error: {
-          code: "policy_denied",
-          message:
-            "blocked by policy: x.com is read-only — grant full access from the reins extension popup",
-        },
-      }),
-    );
-    return;
-  }
-  const result = METHOD_RESULTS[msg.method ?? ""];
-  ws.send(JSON.stringify({ type: "response", id: msg.id, ok: true, result }));
-}
-```
-
-with a module-level `let DENY_CLICKS = false;` reset in `afterEach`.
-
-3. New tests after the existing describe:
-
-```ts
-describe("policy over the bridge", () => {
-  it("routes policy_get and policy_tighten end-to-end", async () => {
-    const port = await setupHarness();
-    expect(await rpc(port, "policy_get")).toEqual({ defaultTier: "full", rules: [] });
-    expect(await rpc(port, "policy_tighten", { pattern: "evil.com", tier: "deny" })).toEqual({
-      defaultTier: "full",
-      rules: [{ pattern: "evil.com", tier: "deny" }],
-    });
-  });
-
-  it("surfaces policy_denied to the HTTP caller", async () => {
-    const port = await setupHarness();
-    DENY_CLICKS = true;
-    const res = await fetch(`http://127.0.0.1:${port}/rpc`, {
-      method: "POST",
-      headers: { "content-type": "application/json" },
-      body: JSON.stringify({ method: "click", params: { ref: "e1" } }),
-    });
-    expect(res.status).toBe(502);
-    const body = (await res.json()) as { error: string };
-    expect(body.error).toMatch(/blocked by policy/);
-    expect(body.error).toMatch(/popup/);
-    // read-tier methods still work in the same session
-    expect(await rpc(port, "read_text")).toEqual({ text: "page text" });
-  });
-});
-```
-
-- [ ] **Step 2: Run to verify the new tests fail, then fix expectations**
-
-Run: `pnpm --filter @reins/protocol build && pnpm --filter @karnstack/reins test -- integration`
-Expected: the two new tests fail before the stand-in edits are saved; all
-pass after. If the daemon's error mapping wraps the message differently
-(check `packages/cli/src/daemon.ts:89` and `bridge.ts`'s request rejection),
-adjust the `body.error` assertions to the actual wrapped text — the
-requirement is that "blocked by policy" and "popup" survive to the CLI
-caller verbatim.
-
-- [ ] **Step 3: Commit**
-
-```bash
-git add packages/cli/src/integration.test.ts

-
-### Task 7: docs + changeset
-
-**Files:**
-- Modify: `skills/reins/SKILL.md` (gotcha entry)
-- Modify: `README.md` (short security paragraph)
-- Create: `.changeset/permission-model.md`
-
-- [ ] **Step 1: SKILL.md gotcha**
-
-Read `skills/reins/SKILL.md`, find the gotchas section, add one entry
-matching its list style:
-
-```markdown
-- Commands can fail with `blocked by policy: <host> is read-only/denied`.
-  The user's site-permission policy blocks that action tier. Do not retry
-  and do not try to change the policy yourself — `reins policy` can only
-  view or tighten. Tell the user which host and tier blocked you and that
-  grants live in the reins extension popup (toolbar icon → Site
-  permissions).
-```
-
-- [ ] **Step 2: README security paragraph**
-
-Read `README.md`, add under the existing security-adjacent section (or
-after the feature list if none):
-
-```markdown
-### Site permissions
-
-reins enforces a per-site policy inside the extension: every host resolves
-to a tier — `deny`, `read` (observation only: tabs/text/snapshot/
-screenshot/console/network), or `full`. Fresh installs default to `full`
-everywhere (zero-config); tighten it with `reins policy deny <host>` /
-`reins policy readonly <host>` or from the extension popup. Loosening is
-popup-only by design — a shell agent cannot grant itself access, because
-the check runs in the extension, not the daemon.
-```
-
-- [ ] **Step 3: Changeset**
-
-Create `.changeset/permission-model.md` (cli gets minor; extension version
-bumps via its own release flow — include it if the repo's existing
-changesets do):
-
-```markdown
----
-"@karnstack/reins": minor
----
-
-Per-site permission tiers (deny/read/full) enforced in the extension.
-`reins policy` shows and tightens policy; grants are popup-only. New
-bridge methods `policy_get`/`policy_tighten`; denied tabs are redacted in
-`list_tabs`. Default remains full access everywhere.
-```
-
-Check `git log`'s previous `Version Packages` PRs / existing `.changeset/*`
-conventions first; mirror how `@reins/extension` bumps are declared (it is
-`private: true`, so it is likely excluded — confirm against
-`.changeset/config.json`).
-
-- [ ] **Step 4: Full verification sweep**
-
-```bash
-pnpm --filter @reins/protocol build
-pnpm -r typecheck
-pnpm -r test
-pnpm --filter @reins/extension build
-```
-
-Expected: all green.
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add skills/reins/SKILL.md README.md .changeset/permission-model.md
-git commit -m "docs: site permissions gotcha, README, changeset"
-```
-
----
-
-## After the plan: PR + review (session workflow, not plan tasks)
-
-1. Push `feat/permission-model`, open PR against `main` titled
-   `feat: per-site permission tiers (deny/read/full)` — body summarizes the
-   spec, links `docs/superpowers/specs/2026-07-11-permission-model-design.md`.
-2. Run `/code-review` via a Fable subagent on the PR diff; triage and fix
-   confirmed findings before merge.

-# Tab Groups Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Give the agent tab-group primitives (`reins groups`, `reins group`, `reins ungroup`, and `groupId` in `reins tabs`) so it can mark and organize tabs. reins never groups anything on its own.
-
-**Architecture:** Each command follows the existing pipeline. First, zod schemas and `METHOD_TIERS` in `@reins/protocol`. Next, a handler in the extension (new `tab-groups.ts`) behind the `dispatch.ts` policy gate. Then daemon routing and aggregation (`rpc.ts`), and finally a CLI `ToolCommand` (`commands.ts`). Browsers without `chrome.tabGroups` answer with error code `unsupported`.
-
-**Tech Stack:** TypeScript, zod, vitest, pnpm + turbo monorepo, Chrome MV3 extension (`@types/chrome` 0.2.0), biome.
-
-**Spec:** `docs/superpowers/specs/2026-09-26-tab-groups-design.md`
-
-## Global Constraints
-
-- The four group methods (`list_groups`, `group_tabs`, `update_group`, `ungroup_tabs`) are all tier `"read"`.
-- Colors are exactly: grey, blue, red, yellow, green, pink, purple, cyan, orange.
-- Unsupported browser → `Error` with `code = "unsupported"`, message `this browser doesn't support tab groups (chrome.tabGroups unavailable)`.
-- `ungroup` never closes tabs.
-- No auto-grouping and no settings toggle.
-- Manual e2e only touches tabs reins opened itself (see memory: never mutate the user's browser-wide state).
-- Rebuild `@reins/protocol` (`pnpm --filter @reins/protocol build`) before running cli or extension tests. They import its `dist`.
-- Two stacked PRs:
-  - PR1 is branch `feat/tab-groups`, Tasks 1–4.
-  - PR2 is branch `feat/tab-groups-write`, cut from PR1, Tasks 5–9.
-- Commit messages: conventional style, ending with `Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>`.

-# PR1 — read side (`feat/tab-groups`)
-
-### Task 1: Protocol — `Tab.groupId`, `TabGroup`, `list_groups`
-
-**Files:**
-- Modify: `packages/protocol/src/bridge.ts` (Tab schema, new TabGroup schemas)
-- Modify: `packages/protocol/src/policy.ts:78-102` (METHOD_TIERS)
-- Test: `packages/protocol/src/bridge.test.ts`, `packages/protocol/src/policy.test.ts:86-119`
-
-**Interfaces:**
-- Produces:
-  - `Tab.groupId?: number`
-  - `TabGroupColor` (zod enum)
-  - `TabGroup { groupId, title, color, collapsed, windowId, tabCount, browserId?, browser? }`
-  - `ListGroupsResult { groups: TabGroup[] }`
-  - `METHOD_TIERS.list_groups = "read"`
-
-- [ ] **Step 1: Write failing tests**
-
-Append to `packages/protocol/src/bridge.test.ts` (and add `ListGroupsResult, TabGroup` to its import from `./bridge.js`):
-
-```ts
-describe("tab groups", () => {
-  it("Tab accepts an optional groupId", () => {
-    expect(Tab.parse({ tabId: 1, title: "t", url: "u", active: true, groupId: 7 }).groupId).toBe(7);
-    expect(Tab.parse({ tabId: 1, title: "t", url: "u", active: true }).groupId).toBeUndefined();
-  });
-
-  it("TabGroup parses a group and rejects unknown colors", () => {
-    const g = {
-      groupId: 7,
-      title: "reins",
-      color: "blue",
-      collapsed: false,
-      windowId: 1,
-      tabCount: 2,
-    };
-    expect(TabGroup.parse(g)).toEqual(g);
-    expect(() => TabGroup.parse({ ...g, color: "magenta" })).toThrow();
-    expect(ListGroupsResult.parse({ groups: [g] }).groups).toHaveLength(1);
-  });
-});
-```
-
-In `packages/protocol/src/policy.test.ts`, change the METHOD_TIERS test:
-- rename it to `"classifies exactly the 24 bridge methods"`
-- add `"list_groups"` to the `read` array
-
-- [ ] **Step 2: Run to verify fail**
-
-Run: `pnpm --filter @reins/protocol test`
-Expected: FAIL. `TabGroup` is not exported, and `list_groups` is not classified.
-
-- [ ] **Step 3: Implement**
-
-In `packages/protocol/src/bridge.ts`, add to the `Tab` object (after `active`):
-
-```ts
-  /** The tab's group, when it is in one (omitted when ungrouped, or when the
-   *  browser has no tab groups). */
-  groupId: z.number().optional(),
-```
-
-After `export type Tab = …`, add:
-
-```ts
-/** Chromium's fixed tab-group palette. */
-export const TabGroupColor = z.enum([
-  "grey",
-  "blue",
-  "red",
-  "yellow",
-  "green",
-  "pink",
-  "purple",
-  "cyan",
-  "orange",
-]);
-export type TabGroupColor = z.infer<typeof TabGroupColor>;
-
-/** A tab group. browserId/browser are tagged by the daemon when aggregating
- *  across several connected browsers. */
-export const TabGroup = z.object({
-  groupId: z.number(),
-  title: z.string(),
-  color: TabGroupColor,
-  collapsed: z.boolean(),
-  windowId: z.number(),
-  tabCount: z.number(),
-  browserId: z.string().optional(),
-  browser: z.string().optional(),
-});
-export type TabGroup = z.infer<typeof TabGroup>;
-```
-
-At the end of the file, add:
-
-```ts
-/** Result payload for the `list_groups` method. */
-export const ListGroupsResult = z.object({ groups: z.array(TabGroup) });
-export type ListGroupsResult = z.infer<typeof ListGroupsResult>;
-```
-
-In `packages/protocol/src/policy.ts` METHOD_TIERS, add `list_groups: "read",` after `list_tabs: "read",`.
-
-- [ ] **Step 4: Run to verify pass**
-
-Run: `pnpm --filter @reins/protocol test && pnpm --filter @reins/protocol build`
-Expected: PASS, and dist rebuilt.
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/protocol/src
-git commit -m "feat(protocol): tab group schema, Tab.groupId, list_groups tier"
-```

-In `packages/extension/src/lib/dispatch.ts`:
-- Add `import { listGroups } from "./tab-groups.js";`
-- In `gate`, change the first early return to
-  `if (method === "list_tabs" || method === "list_groups") return { params: p, meta: {} };`
-- In the doc comment above `gate`, add: "list_groups has no host (group titles are the user's own labels)."

-
-```ts
-    case "list_groups":
-      return listGroups();
-```
-
-In `packages/extension/manifest.config.ts`:
-- Add this comment line after the `tabs:` line:

-Run: `pnpm --filter @reins/extension test && pnpm --filter @reins/extension typecheck`
-Expected: PASS. If typecheck flags `chrome.tabGroups?.` as a non-optional access, keep it anyway: at runtime the namespace can be undefined. If biome complains, add `// biome-ignore lint/complexity/useOptionalChain: undefined outside Chrome proper` or cast through `(chrome as Partial<typeof chrome>)`.

-
-In `packages/cli/src/rpc.ts`:
-- Change the import to `import { ListGroupsResult, ListTabsResult, type ResponseMeta, type Tab, type TabGroup } from "@reins/protocol";`
-- Replace the top of `listAllTabs` with a shared helper:

-
-(If TS doesn't narrow `settled.filter`, use `settled.flatMap((s) => (s.status === "fulfilled" ? s.value : []))`. Keep the `failed` check as it is.)
-
-- In `handleRpc`'s `try`, after the `list_tabs` branch:

-```
-
-In `packages/cli/src/cli-commands.ts`:
-- Change the type import to `import type { BrowserInfo, Tab, TabGroup } from "@reins/protocol";`
-- In `helpText`, change the tabs list to `...["tabs", "groups", "open", "close", "focus", "nav"].map(tool),`
-- Replace `tabsText`'s map line and add `groupsText`:

-
-In `packages/cli/src/commands.ts`:
-- Change the imports to `import type { ConsoleEntry, NetworkEntry, SnapshotRef, Tab, TabGroup } from "@reins/protocol";` and `import { groupsText, tabsText } from "./cli-commands.js";`
-- Add after `tabs:`:
-
-```ts

-### Task 4: PR1 docs, changeset, verification, PR
-
-**Files:**
-- Modify: `skills/reins/SKILL.md` (Commands block ~line 90)
-- Modify: `packages/web/src/routes/docs/commands.tsx:22-30` (tabs group rows)
-- Modify: `docs/CHROME_WEB_STORE.md` (tabGroups justification after the tabs justification ~line 59; the permission list ~line 155; the feature bullet ~line 137)
-- Modify: `docs/PRIVACY.md:11-12`
-- Create: `.changeset/tab-groups-read.md`
-
-- [ ] **Step 1: Docs**
-
-`skills/reins/SKILL.md` Commands block, after the `tabs / open …` line:
-
-```
-groups          tab groups (id, title, color); `tabs` shows g<id> per grouped tab
-```
-
-`packages/web/src/routes/docs/commands.tsx`, after the `reins tabs` row:
-
-```ts
-      [
-        "reins groups [--browser <id>]",
-        "List tab groups. reins tabs marks each grouped tab with g<id>.",
-      ],
-```
-
-`docs/CHROME_WEB_STORE.md`:
-- After the tabs justification block, add:
-
-````md
-**tabGroups justification**
-
-```text
-Lists the user's tab groups (title, color, collapsed state) and, on the agent's behalf, creates groups, adds or removes tabs, and edits a group's title and color — so the user can see which tabs their agent is working in. Group metadata is sent only to the user's own local daemon on 127.0.0.1, never to a remote server.
-```
-````
-
-- In the "PERMISSIONS, AND WHY" list, add after the `tabs` bullet:
-  `• tabGroups — list, create, and edit tab groups, so you can see which tabs your agent is working in.`
-- Change the `• Tabs — …` feature bullet (~line 137) to:
-  `• Tabs — list, open, close, focus, and group tabs across every connected browser`
-
-`docs/PRIVACY.md` line 11: change "**Page content and tab metadata** (titles, URLs, …" to "**Page content and tab metadata** (titles, URLs, tab group names, …". Also update `_Last updated:` to `2026-09-26`.
-
-- [ ] **Step 2: Changeset**
-
-Create `.changeset/tab-groups-read.md`:
-
-```md
----
-"@karnstack/reins": minor
-"@reins/extension": minor
----
-
-`reins groups` lists tab groups (title, color, collapsed, tab count) across connected browsers, and `reins tabs` marks each grouped tab with `g<id>`. Browsers without tab groups (Arc, Dia) answer `unsupported` instead of failing silently. The extension asks for the `tabGroups` permission, which shows no install prompt.
-```
-
-(Check `.changeset/config.json`. If `@reins/protocol` is not ignored/private, add `"@reins/protocol": minor` too.)
-
-- [ ] **Step 3: Full verification**
-
-Run: `pnpm build && pnpm test && pnpm typecheck && pnpm lint`
-Expected: all pass.
-
-- [ ] **Step 4: Manual e2e (real Chrome, own tabs only)**
-
-Follow `local-dev-setup` and `sideload-bundle-order` from memory: `pnpm build` → reload the extension (`reins extension --reload`) → `reins kill`. Then:
-
-```bash
-reins groups                      # lists the user's existing groups (read-only), or "(no groups)"
-reins tabs | grep ' g' | head -3  # grouped tabs show g<id>
-```
-
-Expected: no errors. Nothing is mutated in PR1.

-
-- [ ] **Step 1: Failing tests**
-

-
-Note: `afterEach` already runs `vi.clearAllMocks()`. `mockImplementation` persists across tests unless reset, so add `vi.mocked(ensureAllowed).mockReset(); vi.mocked(ensureAllowed).mockResolvedValue(undefined as never);` in a `beforeEach` inside this describe (import `beforeEach` from vitest).
-
-- [ ] **Step 2: Run, verify fail**
-
-Run: `pnpm --filter @reins/extension test -- dispatch`
-Expected: FAIL ("unknown method" or the gate calling `resolveTabId`).
-
-- [ ] **Step 3: Implement**
-
-In `dispatch.ts`:
-- Add `GroupTabsParams, UngroupTabsParams, UpdateGroupParams` to the `@reins/protocol` import.
-- Replace the tab-groups import with `import { groupTabIds, groupTabs, listGroups, requireGroups, ungroupTabs, updateGroup } from "./tab-groups.js";`
-
-Add this helper above `gate`:
-
-```ts
-/** Check every target tab's host; the first denial refuses the whole call,
- *  tagged with that tab for the audit trail. */
-async function ensureTabsAllowed(method: GatedMethod, tabIds: number[]): Promise<void> {
-  for (const tabId of tabIds) {
-    const tab = await chrome.tabs.get(tabId);
-    try {
-      await ensureAllowed(method, hostOf(tab.url ?? ""));
-    } catch (err) {
-      if (err instanceof PolicyDenied && err.meta) err.meta = { ...err.meta, tabId };
-      throw err;
-    }
-  }
-}
-```
-
-In `gate`, replace the first line after `const p = …`:
-
-```ts
-  if (method === "list_tabs" || method === "list_groups") return { params: p, meta: {} };
-  if (method === "update_group") {
-    requireGroups();
-    return { params: UpdateGroupParams.parse(p), meta: {} };
-  }
-  if (method === "group_tabs" || method === "ungroup_tabs") {
-    // Before any lookup: on a browser without groups, tabs.query({groupId})
-    // may ignore the filter and return every tab.
-    requireGroups();
-    const parsed = (method === "group_tabs" ? GroupTabsParams : UngroupTabsParams).parse(p);
-    const tabIds = parsed.tabIds ?? (await groupTabIds(parsed.groupId as number));
-    await ensureTabsAllowed(method, tabIds);
-    return { params: { ...parsed, tabIds }, meta: {} };
-  }
-```
-
-Update the doc comment above `gate`: "Group ops check every target tab (for a whole group, its current tabs) and pin that set in params; update_group only edits the group's label."
-
-In `runHandler`, add after `list_groups`:
-
-```ts
-    case "group_tabs":
-      return groupTabs(gated as Parameters<typeof groupTabs>[0]);
-    case "update_group":
-      return updateGroup(gated as Parameters<typeof updateGroup>[0]);
-    case "ungroup_tabs":
-      return ungroupTabs(gated as Parameters<typeof ungroupTabs>[0]);
-```
-
-- [ ] **Step 4: Run, verify pass**
-
-Run: `pnpm --filter @reins/extension test && pnpm --filter @reins/extension typecheck`
-Expected: PASS, all existing dispatch tests included.
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/extension/src/lib/dispatch.ts packages/extension/src/lib/dispatch.test.ts
-git commit -m "feat(extension): policy gate for tab group ops"

-
-**Files:**
-- Modify: `packages/cli/src/commands.ts` (ToolCommand `methodFor`, two commands)
-- Modify: `packages/cli/src/cli.ts:55` (use `methodFor`)
-- Modify: `packages/cli/src/cli-commands.ts` (help list)

-  - `TOOL_COMMANDS.group`, `TOOL_COMMANDS.ungroup`
-
-- [ ] **Step 1: Failing tests**
-
-Append to `describe("TOOL_COMMANDS: params", …)` in `commands.test.ts`:
-
-```ts
-  it("group: repeatable --tab creates a group; props map through", () => {
-    const p = build("group", ["--tab", "12", "--tab", "13", "--title", "reins", "--color", "blue"]);

-```
-
-- [ ] **Step 2: Run, verify fail**
-
-Run: `pnpm --filter @reins/protocol build && pnpm --filter @karnstack/reins test -- commands`
-Expected: FAIL (no such command: group).
-
-- [ ] **Step 3: Implement**
-
-In `commands.ts`, add to the `ToolCommand` interface after `method: string;`:
-
-```ts
-  /** Pick the bridge method from the built params, when one command covers
-   *  several (default: `method`). */
-  methodFor?(params: Record<string, unknown>): string;
-```
-
-Add helpers after `oneOf`:
-
-```ts
-const GROUP_COLORS = ["grey", "blue", "red", "yellow", "green", "pink", "purple", "cyan", "orange"];
-
-/** Repeatable --tab → tab ids (undefined when absent). */
-function tabList(a: ParsedArgs): number[] | undefined {
-  const v = a.flags.tab;
-  if (v === undefined) return undefined;
-  const list = Array.isArray(v) ? v : [v];
-  return list.map((s) => {
-    const n = Number(s);
-    if (typeof s !== "string" || !Number.isInteger(n)) {
-      throw new UsageError(`--tab must be an integer, got "${String(s)}"`);
-    }
-    return n;
-  });
-}
-
-/** --title / --color / --collapse|--expand → group props. */
-function groupProps(a: ParsedArgs): Record<string, unknown> {
-  const out: Record<string, unknown> = {};
-  const title = flagStr(a, "title");
-  if (title !== undefined) out.title = title;
-  const color = oneOf(a, "color", GROUP_COLORS);
-  if (color !== undefined) out.color = color;
-  if (a.flags.collapse === true && a.flags.expand === true) {
-    throw new UsageError("--collapse and --expand are mutually exclusive");
-  }
-  if (a.flags.collapse === true) out.collapsed = true;

-}
-
-function browserOnly(a: ParsedArgs): Record<string, unknown> {
-  const browser = flagStr(a, "browser");
-  return browser !== undefined ? { browserId: browser } : {};
-}
-```
-
-(Refactor `tabs.build` and `groups.build` to `browserOnly(a)` while here.)
-
-Add the commands after `groups:`:
-
-```ts
-  group: {
-    method: "group_tabs",
-    methodFor: (p) => (p.tabIds === undefined ? "update_group" : "group_tabs"),
-    usage:
-      "reins group --tab <id> [--tab <id> …] [--group <gid>] [--title <t>] [--color <c>] [--collapse|--expand]\n       reins group --group <gid> [--title <t>] [--color <c>] [--collapse|--expand]",
-    summary: "group tabs (new group, or --group to add/edit one)",

-      const groupId = flagInt(a, "group");
-      const props = groupProps(a);
-      if (tabIds === undefined && groupId === undefined) {
-        throw new UsageError("--tab (to group tabs) or --group (to edit a group) is required");
-      }
-      if (tabIds === undefined && Object.keys(props).length === 0) {
-        throw new UsageError("editing a group needs --title, --color, --collapse or --expand");
-      }
-      return {
-        ...browserOnly(a),
-        ...(tabIds !== undefined ? { tabIds } : {}),
-        ...(groupId !== undefined ? { groupId } : {}),
-        ...props,
-      };
-    },
-    format: (r) => {
-      const g = r as { groupId?: number };
-      return g.groupId !== undefined ? `group ${g.groupId}` : "ok";
-    },
-  },
-  ungroup: {
-    method: "ungroup_tabs",
-    usage: "reins ungroup --tab <id> [--tab <id> …] | --group <gid>",

-      }
-      return {
-        ...browserOnly(a),
-        ...(tabIds !== undefined ? { tabIds } : { groupId }),
-      };
-    },
-    format: ok,
-  },
-```
-
-In `cli.ts:55`, change the call to `const result = await rpc(ensured.port, cmd.methodFor?.(params) ?? cmd.method, params);`
-
-In `cli-commands.ts` `helpText`, change the tabs list to `["tabs", "groups", "group", "ungroup", "open", "close", "focus", "nav"]`.
-
-Check `format`'s helper in the test: it calls `c.format?.(result, parseArgs(argv))`, which works as is.
-
-- [ ] **Step 4: Run, verify pass**
-
-Run: `pnpm --filter @karnstack/reins test && pnpm --filter @karnstack/reins typecheck`
-Expected: PASS. The "every command has a usage line" test must see `reins group` and `reins ungroup` in their usage.

-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/cli/src
-git commit -m "feat(cli): reins group and reins ungroup"

-### Task 9: PR2 docs, changeset, e2e, PR
-
-**Files:**
-- Modify: `skills/reins/SKILL.md`
-- Modify: `packages/web/src/routes/docs/commands.tsx`
-- Create: `.changeset/tab-groups-write.md`
-
-- [ ] **Step 1: Docs**
-
-`skills/reins/SKILL.md` Commands block, replace the `groups` line from Task 4 with:
-
-```
-groups          tab groups (id, title, color); `tabs` shows g<id> per grouped tab
-group           --tab <id> [--tab …] [--group <gid>] [--title T] [--color blue] [--collapse|--expand]
-                no --tab + --group <gid>: edit that group
-ungroup         --tab <id> [--tab …] | --group <gid>   (tabs stay open)
-```
-
-Add a short paragraph after the Commands block (or in the tips section):
-
-```md
-**Tab groups.** You can put the tabs you open for a task into a group
-(`reins group --tab 12 --tab 13 --title reins --color blue`) so the user sees
-which tabs are yours. Don't regroup the user's own tabs unless they ask.
-Arc and Dia have no tab groups; those commands answer `unsupported` there.
-```
-
-`packages/web/src/routes/docs/commands.tsx`, after the `reins groups` row:
-
-```ts
-      [
-        "reins group --tab <id> [--tab <id> …] [--group <gid>] [--title <t>] [--color <c>] [--collapse|--expand]",
-        "Put tabs in a new group, or in an existing one with --group. With --group and no --tab, edit the group.",
-      ],
-      [
-        "reins ungroup --tab <id> [--tab <id> …] | --group <gid>",
-        "Take tabs out of their group, or dissolve a whole group. Tabs stay open.",
-      ],
-```
-
-- [ ] **Step 2: Changeset**
-
-Create `.changeset/tab-groups-write.md` (add `@reins/protocol` if Task 4 found it versioned):
-
-```md
----
-"@karnstack/reins": minor
-"@reins/extension": minor
----
-
-`reins group` puts tabs in a new or existing tab group and edits a group's title, color, and collapsed state. `reins ungroup` takes tabs out of their group or dissolves a whole group, and never closes tabs. reins groups nothing on its own; the agent decides. Group operations count as reading: read-only sites can be grouped, denied sites cannot.
-```
-
-- [ ] **Step 3: Full verification**
-
-Run: `pnpm build && pnpm test && pnpm typecheck && pnpm lint`
-Expected: all pass.
-
-- [ ] **Step 4: Manual e2e (real Chrome, only tabs reins opens)**
-
-Rebuild and reload per memory: `pnpm build` → `reins extension --reload` → `reins kill`. Then:
-
-```bash
-A=$(reins open https://example.com --background --json | jq .tabId)
-B=$(reins open https://example.org --background --json | jq .tabId)
-G=$(reins group --tab $A --tab $B --title reins-e2e --color orange --json | jq .groupId)
-reins groups | grep reins-e2e              # 2 tabs, orange
-reins tabs | grep "g$G"                    # both tabs marked
-reins group --group $G --collapse && reins groups | grep collapsed
-reins ungroup --tab $A && reins groups | grep reins-e2e   # 1 tab
-reins ungroup --group $G && reins groups | grep -c reins-e2e   # 0 — group gone
-reins close --tab $A && reins close --tab $B              # cleanup
-```
-
-Expected: every step matches the comment, and the user's own tabs and groups are unchanged. If a Dia or Arc browser is connected, run `reins group --browser <id> --tab <id> …` and confirm it answers `unsupported: …`.
-
-- [ ] **Step 5: Commit, push, stacked PR**
-
-```bash
-git add skills packages/web .changeset
-git commit -m "docs: reins group / ungroup"
-git push -u origin feat/tab-groups-write
-gh pr create --base feat/tab-groups --title "feat: reins group / ungroup" --body "Stacked on #<PR1>. …summary, test plan…

-# reins do Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Ship `reins do "<goal>"`: the calling agent hands one small browser task to a Jev (TypeSafe) loop that runs in the daemon. The agent supplies typed values with `--fill` and gets back a result plus the exact next command. Users store one TypeSafe key, from the CLI or from the extension popup.
-
-**Architecture:**
-- The key lives in `~/.reins/credentials.json`, which only the daemon reads. The popup reaches the daemon through a new extension→daemon `call` frame.
-- The loop runs in the daemon (`packages/cli/src/jev/`) and calls TypeSafe through the official SDK. It drives the tab through two new bridge methods, `jev_observe` and `jev_act`.
-- Those two methods live in the extension (`lib/jev.ts`, `lib/jev-snapshot.ts`). They reuse the existing click path (`actionPoint` → press → landing probe).
-
-**Tech Stack:** TypeScript 6, zod 4, vitest 4, pnpm + turbo, tsdown (CLI), vite + crxjs (MV3 extension), `@typesafe-ai/sdk` 0.6.0, biome.
-
-**Spec:** `docs/superpowers/specs/2026-09-27-reins-do-design.md`
-
-## Global Constraints
-
-- Rebuild `@reins/protocol` (`pnpm --filter @reins/protocol build`) before running cli or extension tests. They import its `dist`.
-- Pin every new dependency exactly: `"@typesafe-ai/sdk": "0.6.0"`.
-- Only the daemon talks to TypeSafe. The extension never makes a remote request, and `manifest.config.ts` stays unchanged.
-- The key is never returned by any method (status returns only `set` + `last4`), never logged, and never sent to a page.
-- Tests never call the paid API. Inject `fetch` into the SDK client, or inject a fake `ask`.
-- Default budgets: `--max-steps 30`, `--timeout 60` (seconds). The Jev-call cap per invocation is `2 × max-steps`. `jev_act` uses an actionability timeout of `500` ms.
-- Exit codes for `reins do`: `0` done, `1` error, `2` every other status.
-- Risky words (whole-word, case-insensitive): `buy, pay, purchase, order, checkout, send, post, publish, share, invite, delete, remove, transfer, unsubscribe, approve, authorize, accept`.
-- Manual testing only ever drives tabs reins opened itself. Never clear or reset browser-wide state (see memory).
-- Stacked PRs:
-  - PR1 `feat/reins-do` (already has the spec commit): Tasks 1–8
-  - PR2 `feat/reins-do-extension`, cut from PR1: Tasks 9–12
-  - PR3 `feat/reins-do-loop`, cut from PR2: Tasks 13–21
-- Commit messages: conventional style, ending with `Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>`.
-- Dev loop after CLI/daemon changes: `pnpm build` → `reins restart`. After extension changes: `pnpm build && reins extension --reload`.

-# PR1 — key plumbing (`feat/reins-do`)
-
-### Task 1: Protocol — `CallFrame` and key schemas
-
-**Files:**
-- Modify: `packages/protocol/src/bridge.ts` (append after `WelcomeFrame`)
-- Test: `packages/protocol/src/bridge.test.ts`
-
-**Interfaces:**
-- Produces:
-  - `CallFrame { type: "call"; id: string; method: string; params: unknown }`
-  - `CALL_METHODS = ["key_set", "key_status", "key_clear"] as const`, and `CallMethod`
-  - `KeyProvider` (zod enum `"typesafe"`)
-  - `KeySetParams { provider: "typesafe"; key: string }`, where `provider` defaults to `"typesafe"` and `key` is trimmed, at least 8 chars
-  - `KeyProviderParams { provider: "typesafe" }`, with `provider` defaulting as above
-  - `KeyStatus { provider: "typesafe"; set: boolean; last4?: string }`
-
-- [ ] **Step 1: Write the failing tests**
-
-Append to `packages/protocol/src/bridge.test.ts`, and add `CALL_METHODS, CallFrame, KeySetParams, KeyStatus` to its import from `./bridge.js`:
-
-```ts
-describe("call frames (extension → daemon)", () => {
-  it("parses a call frame", () => {
-    const f = { type: "call", id: "c1", method: "key_status", params: {} };
-    expect(CallFrame.parse(f)).toEqual(f);
-    expect(() => CallFrame.parse({ ...f, id: "" })).toThrow();
-  });
-
-  it("allows exactly the three key methods", () => {
-    expect([...CALL_METHODS]).toEqual(["key_set", "key_status", "key_clear"]);
-  });
-
-  it("defaults the provider and trims the key", () => {
-    expect(KeySetParams.parse({ key: "  ts_abcdefgh  " })).toEqual({
-      provider: "typesafe",
-      key: "ts_abcdefgh",
-    });
-    expect(() => KeySetParams.parse({ key: "short" })).toThrow();
-    expect(() => KeySetParams.parse({ provider: "openai", key: "ts_abcdefgh" })).toThrow();
-  });
-
-  it("KeyStatus carries only set + last4", () => {
-    expect(KeyStatus.parse({ provider: "typesafe", set: true, last4: "a1b2" })).toEqual({
-      provider: "typesafe",
-      set: true,
-      last4: "a1b2",
-    });
-  });
-});
-```
-
-- [ ] **Step 2: Run to verify fail**
-
-Run: `pnpm --filter @reins/protocol test`
-Expected: FAIL, `CallFrame` is not exported.
-
-- [ ] **Step 3: Implement**
-
-Append to `packages/protocol/src/bridge.ts` after `WelcomeFrame`:
-
-```ts
-/** Extension → server: invoke one of the few daemon methods the extension may
- *  call (the popup's key management). Answered with a ResponseFrame carrying

-      }
-      throw new Error(`unknown key method: ${method}`);
-    },
-  };
-}
-```
-
-Run: `pnpm --filter @karnstack/reins test -- jev/keys`
-Expected: PASS.
-
-- [ ] **Step 3: Write the failing RPC, audit and bridge tests**
-
-In `packages/cli/src/rpc.test.ts`, add inside `describe("handleRpc", …)`:
-
-```ts
-  it("answers key methods in the daemon, never forwarding them to a browser", async () => {
-    const bridge = fakeBridge();
-    const keys = { handle: vi.fn(async () => ({ provider: "typesafe" as const, set: false })) };
-    const records: AuditRecord[] = [];
-    const result = await handleRpc(
-      bridge,
-      { method: "key_set", params: { key: "ts_live_abcd1234" } },
-      (r) => records.push(r),
-      { keys },
-    );
-    expect(result).toEqual({ provider: "typesafe", set: false });
-    expect(keys.handle).toHaveBeenCalledWith("key_set", { key: "ts_live_abcd1234" });
-    expect(bridge.requestFull).not.toHaveBeenCalled();
-    expect(JSON.stringify(records)).not.toContain("abcd1234");
-  });
-```
-
-In `packages/cli/src/audit.test.ts`, add to the `redactParams` tests:
-
-```ts
-  it("never writes an API key", () => {
-    expect(redactParams("key_set", { provider: "typesafe", key: "ts_live_abcd1234" })).toEqual({
-      provider: "typesafe",
-      key: "[redacted]",
-    });
-  });
-```
-
-In `packages/cli/src/bridge.test.ts`, add. It reuses `connectClient`, `ALLOWED`, the module-level `host`, and the `BridgeHost` import already in the file:
-
-```ts
-describe("call frames from the extension", () => {
-  async function startWith(onCall?: (m: string, p: unknown, b: string) => Promise<unknown>) {
-    host = new BridgeHost({
-      allowedOrigins: new Set([ALLOWED]),
-      log: () => {},
-      ...(onCall ? { onCall } : {}),
-    });
-    await host.listen(0);
-    return connectClient(host.port);
-  }
-
-  function callAndWait(ws: WebSocket, frame: Record<string, unknown>) {
-    return new Promise<Record<string, unknown>>((resolve) => {
-      ws.on("message", (data) => {
-        const msg = JSON.parse(data.toString());
-        if (msg.type === "response" && msg.id === frame.id) resolve(msg);
-      });
-      ws.send(JSON.stringify(frame));
-    });
-  }
-
-  it("answers an allowed call with the handler's result", async () => {
-    const onCall = vi.fn(async () => ({ provider: "typesafe", set: false }));
-    const ws = await startWith(onCall);
-    const reply = await callAndWait(ws, { type: "call", id: "c1", method: "key_status", params: {} });
-    expect(reply).toMatchObject({ ok: true, result: { set: false } });
-    expect(onCall).toHaveBeenCalledWith("key_status", {}, "b1");
-    ws.close();
-  });
-
-  it("refuses any method outside the key methods", async () => {
-    const onCall = vi.fn(async () => ({}));
-    const ws = await startWith(onCall);
-    const reply = await callAndWait(ws, { type: "call", id: "c2", method: "click", params: {} });
-    expect(reply).toMatchObject({ ok: false, error: { code: "METHOD_NOT_ALLOWED" } });
-    expect(onCall).not.toHaveBeenCalled();
-    ws.close();
-  });
-
-  it("returns a handler failure as an error response", async () => {
-    const ws = await startWith(async () => {
-      throw new Error("TypeSafe rejected the API key");
-    });
-    const reply = await callAndWait(ws, { type: "call", id: "c3", method: "key_set", params: {} });
-    expect(reply).toMatchObject({
-      ok: false,
-      error: { code: "CALL_FAILED", message: "TypeSafe rejected the API key" },
-    });
-    ws.close();
-  });
-});
-```
-
-(Add `vi` to the vitest import in `bridge.test.ts` if it isn't there.)
-
-- [ ] **Step 4: Run to verify fail**
-
-Run: `pnpm --filter @karnstack/reins test -- rpc audit bridge`
-Expected: FAIL. `handleRpc` has no 4th param, `key` isn't redacted, and `onCall` is unknown.
-
-- [ ] **Step 5: Implement**
-
-`packages/cli/src/audit.ts`, in `redactParams`, add a branch before the final `else`:
-
-```ts
-    } else if (method === "key_set" && key === "key") {
-      out[key] = "[redacted]";
-```
-
-`packages/cli/src/rpc.ts`:
-
-```ts
-// add to imports
-import { KEY_METHODS, type KeyService } from "./jev/keys.js";
-
-/** Daemon-side services and the per-request abort signal. */
-export interface RpcContext {
-  keys?: KeyService;
-  /** Aborted when the CLI hangs up or the daemon shuts down. */
-  signal?: AbortSignal;
-}
-```
-
-Change the signature to `export async function handleRpc(bridge: BridgePort, body: unknown, audit?: AuditHook, ctx: RpcContext = {}): Promise<unknown>`. Inside the `try`, before the `list_tabs` branch, add:
-
-```ts
-    if (KEY_METHODS.has(method)) {
-      if (!ctx.keys) throw new Error(`${method} is not available in this daemon`);
-      const status = await ctx.keys.handle(method, params);
-      finish({ ok: true });
-      return status;
-    }
-```
-
-`packages/cli/src/bridge.ts`:
-- Import `CALL_METHODS` and `CallFrame` from `@reins/protocol`.
-- Add a field `readonly #onCall?: (method: string, params: unknown, browserId: string) => Promise<unknown>;`.
-- In the constructor, change the opts type to `{ allowedOrigins: ReadonlySet<string>; log?: Log; onCall?: (method: string, params: unknown, browserId: string) => Promise<unknown> }` and add `this.#onCall = opts.onCall;`.
-- In `#onConnection`'s message handler, after the `ResponseFrame` branch, add:
-
-```ts
-      const call = CallFrame.safeParse(msg);
-      if (call.success) void this.#answerCall(ws, browserId, call.data);
-```
-
-Then add the method:
-
-```ts
-  /** Extension → daemon: only the key methods, answered with a ResponseFrame. */
-  async #answerCall(ws: WebSocket, browserId: string, frame: CallFrame): Promise<void> {
-    let reply: ResponseFrame;
-    if (!this.#onCall || !(CALL_METHODS as readonly string[]).includes(frame.method)) {
-      reply = {
-        type: "response",
-        id: frame.id,
-        ok: false,
-        error: { code: "METHOD_NOT_ALLOWED", message: `${frame.method} can't be called from the extension` },
-      };
-    } else {
-      try {
-        const result = await this.#onCall(frame.method, frame.params, browserId);
-        reply = { type: "response", id: frame.id, ok: true, result };
-      } catch (err) {
-        reply = {
-          type: "response",
-          id: frame.id,
-          ok: false,
-          error: { code: "CALL_FAILED", message: err instanceof Error ? err.message : String(err) },
-        };
-      }
-    }
-    if (ws.readyState === WebSocket.OPEN) ws.send(JSON.stringify(reply));
-  }
-```
-
-`packages/cli/src/daemon.ts`:
-- Import `type RpcContext` from `./rpc.js`.
-- Add `context?: Omit<RpcContext, "signal">;` to the `startDaemon` opts.
-- Change the `/rpc` call to `handleRpc(opts.bridge, body, opts.audit, { ...opts.context })`. Task 18 adds the signal.
-
-`packages/cli/src/serve.ts`, in `runDaemon`:
-
-```ts
-import { createKeyService } from "./jev/keys.js";
-import { handleRpc } from "./rpc.js";
-// …
-  const keys = createKeyService({ dir: config.dir });
-  const bridge: BridgeHost = new BridgeHost({
-    allowedOrigins: loadAllowedOrigins(config.dir),
-    log,
-    // Popup key saves go through the same audited path as `reins key`.
-    onCall: (method, params) => handleRpc(bridge, { method, params }, audit, { keys }),
-  });
-```
-
-Also pass `context: { keys }` to `startDaemon({ … })`. `config` is currently created after `bridge`; move `const config = loadOrCreateConfig();` above it.
-
-- [ ] **Step 6: Run to verify pass**
-
-Run: `pnpm --filter @karnstack/reins test && pnpm --filter @karnstack/reins typecheck`
-Expected: PASS.

-In `#onClose()` (after `this.#socket = undefined;`) and in `stop()`, call `this.#rejectCalls("disconnected from the reins daemon");`.
-
-In `offscreen.ts`, change the listener signature to `(msg: unknown, _sender: chrome.runtime.MessageSender, sendResponse: (response?: unknown) => void)`, and add before the `offscreen:disconnect` branch:
-
-```ts
-  // Popup → daemon (key management). Answered here: the offscreen document
-  // owns the socket. Returning true keeps the channel open for the reply.
-  if (message.type === "reins:call") {
-    if (!client) {
-      sendResponse({ error: "not connected to the reins daemon" });
-      return;
-    }
-    client.call(String(message.method), message.params).then(
-      (result) => sendResponse({ result }),
-      (err: unknown) => sendResponse({ error: err instanceof Error ? err.message : String(err) }),
-    );
-    return true;
-  }
-```

-### Task 7: Extension — popup Jev section
-
-**Files:**
-- Create: `packages/extension/src/lib/jev-view.ts`
-- Modify: `packages/extension/src/popup.html`, `packages/extension/src/popup.ts`, `packages/extension/src/popup.css`
-- Test: `packages/extension/src/lib/jev-view.test.ts`
-
-**Interfaces:**
-- Consumes: the `reins:call` runtime message (Task 6); `KeyStatus` (Task 1)
-- Produces:
-  - `type JevKeyState = { kind: "offline" } | { kind: "unset" } | { kind: "set"; last4: string } | { kind: "error"; message: string }`
-  - `jevStateFrom(connected: boolean, status: unknown): JevKeyState`
-  - `jevReadyText(last4: string): string`
-
-- [ ] **Step 1: Write the failing tests**
-
-```ts
-// packages/extension/src/lib/jev-view.test.ts
-import { describe, expect, it } from "vitest";
-import { jevReadyText, jevStateFrom } from "./jev-view.js";
-
-describe("popup Jev state", () => {
-  it("is offline when the daemon isn't connected", () => {
-    expect(jevStateFrom(false, undefined)).toEqual({ kind: "offline" });
-  });
-  it("shows the pitch when no key is set", () => {
-    expect(jevStateFrom(true, { provider: "typesafe", set: false })).toEqual({ kind: "unset" });
-  });
-  it("shows the last 4 when set", () => {
-    expect(jevStateFrom(true, { provider: "typesafe", set: true, last4: "a1b2" })).toEqual({
-      kind: "set",
-      last4: "a1b2",
-    });
-    expect(jevReadyText("a1b2")).toBe("Jev ready · ••••a1b2");
-  });
-  it("reports an unreadable status", () => {
-    expect(jevStateFrom(true, { nope: 1 }).kind).toBe("error");
-  });
-});
-```
-
-- [ ] **Step 2: Run to verify fail**
-
-Run: `pnpm --filter @reins/extension test -- jev-view`
-Expected: FAIL.
-
-- [ ] **Step 3: Implement the view helper**
-
-```ts
-// packages/extension/src/lib/jev-view.ts
-import { KeyStatus } from "@reins/protocol";
-
-export type JevKeyState =
-  | { kind: "offline" }
-  | { kind: "unset" }
-  | { kind: "set"; last4: string }
-  | { kind: "error"; message: string };
-
-export function jevStateFrom(connected: boolean, status: unknown): JevKeyState {
-  if (!connected) return { kind: "offline" };
-  const parsed = KeyStatus.safeParse(status);
-  if (!parsed.success) {
-    return { kind: "error", message: "couldn't read the key status from the reins daemon" };
-  }
-  return parsed.data.set ? { kind: "set", last4: parsed.data.last4 ?? "????" } : { kind: "unset" };
-}
-
-export function jevReadyText(last4: string): string {
-  return `Jev ready · ••••${last4}`;
-}
-```
-
-- [ ] **Step 4: Add the markup**
-
-In `popup.html`, insert after the `toggle` button and before `<section class="reins__policy">`:
-
-```html
-      <section class="reins__jev" id="jev" aria-labelledby="jev-title">

-            aria-label="TypeSafe API key"
-            placeholder="paste TypeSafe key"
-            autocomplete="off"
-            spellcheck="false"
-          />
-          <button class="reins__btn" id="jev-save" type="submit">Save</button>

-        <p class="reins__jev-note" id="jev-offline" hidden>
-          Start reins to save a key. Only the reins daemon can write the key file.
-        </p>

-        </p>
-      </section>
-```
-
-In `popup.css`, append:
-
-```css
-/* Jev key */
-.reins__jev {
-  display: flex;
-  flex-direction: column;
-  gap: 10px;
-  border-top: 1px solid var(--line);
-  padding-top: 12px;
-}
-
-.reins__jev-pitch,
-.reins__jev-note {

-}
-
-.reins__jev-error {
-  margin: 0;
-  font-size: 12px;
-  color: var(--err);
-}
-```
-
-Also add `.reins__jev-pitch code` to the selector list of the existing `.reins__hint code` rule, so inline code matches.
-
-- [ ] **Step 5: Wire the popup**
-
-In `popup.ts`, add near the top-level imports: `import { jevReadyText, jevStateFrom } from "./lib/jev-view.js";`. Then append:
-
-```ts
-// ─── Jev key ─────────────────────────────────────────────────────────────────
-// The key lives in ~/.reins/credentials.json, written only by the daemon. The
-// popup sends it once (reins:call → offscreen → daemon) and afterwards only
-// ever sees whether a key is set and its last four characters.
-
-const jevPitch = document.getElementById("jev-pitch") as HTMLElement;
-const jevReady = document.getElementById("jev-ready") as HTMLElement;
-const jevForm = document.getElementById("jev-form") as HTMLFormElement;

-const jevRemove = document.getElementById("jev-remove") as HTMLButtonElement;
-const jevOffline = document.getElementById("jev-offline") as HTMLElement;
-const jevError = document.getElementById("jev-error") as HTMLElement;
-
-let jevReplacing = false;
-
-async function jevCall(method: string, params: Record<string, unknown> = {}): Promise<unknown> {
-  const res = (await chrome.runtime.sendMessage({ type: "reins:call", method, params })) as
-    | { result?: unknown; error?: string }

-    }
-  }
-  const state = error ? { kind: "error" as const, message: error } : jevStateFrom(connected, status);
-  const set = state.kind === "set";
-  jevPitch.hidden = set && !jevReplacing;
-  jevReady.hidden = !set;
-  if (set) jevReady.textContent = jevReadyText(state.last4);
-  jevForm.hidden = set && !jevReplacing;
-  jevActions.hidden = !set || jevReplacing;
-  jevOffline.hidden = state.kind !== "offline";
-  jevKey.disabled = jevSave.disabled = state.kind === "offline";
-  showJevError(state.kind === "error" ? state.message : undefined);
-}
-
-jevForm.addEventListener("submit", (ev) => {
-  ev.preventDefault();
-  const key = jevKey.value.trim();
-  if (!key) return;
-  jevSave.disabled = true;
-  jevSave.textContent = "Checking…";
-  void jevCall("key_set", { provider: "typesafe", key })
-    .then(() => {
-      jevKey.value = "";
-      jevReplacing = false;
-      return renderJev(true);
-    })
-    .catch((err: unknown) => showJevError(err instanceof Error ? err.message : String(err)))

-    });
-});
-
-jevReplace.addEventListener("click", () => {
-  jevReplacing = true;
-  void renderJev(true).then(() => jevKey.focus());
-});
-
-jevRemove.addEventListener("click", () => {
-  void jevCall("key_clear", { provider: "typesafe" })
-    .then(() => renderJev(true))
-    .catch((err: unknown) => showJevError(err instanceof Error ? err.message : String(err)));
-});
-```
-
-In `refresh()`, after `render(normalizeStatus(res?.status), res?.info);`, add `void renderJev(normalizeStatus(res?.status) === "connected");`. In its `catch`, add `void renderJev(false);`. Status updates already call `refresh()`, so a reconnect or restart re-fetches the key status.
-
-- [ ] **Step 6: Run tests, then check by hand**
-
-Run: `pnpm --filter @reins/extension test && pnpm --filter @reins/extension typecheck && pnpm lint`
-Expected: PASS.
-
-Then `pnpm build && reins extension --reload`, open the popup, and check the three states:
-- connected with no key → pitch + input
-- after `reins key set` → `Jev ready · ••••xxxx` with Replace / Remove
-- after `reins kill` → input disabled, "Start reins to save a key"
-

-### Task 8: PR1 docs and changeset
-
-**Files:**
-- Modify: `docs/PRIVACY.md`, `docs/SECURITY.md`, `docs/CHROME_WEB_STORE.md`
-- Modify: `packages/web/src/routes/docs/security.tsx`, `packages/web/src/routes/docs/commands.tsx`
-- Create: `.changeset/reins-key.md`
-
-- [ ] **Step 1: PRIVACY.md.** Add a section after "What reins does NOT do":
-
-```md
-## Optional: reins do with Jev
-
-`reins do` is off until you save a TypeSafe API key (`reins key set typesafe`,
-or the Jev section of the extension popup). The key is stored in
-`~/.reins/credentials.json` on your machine (readable only by you) and is read
-only by the local reins daemon.
-
-While a `reins do` run is working, the **daemon** (not the extension) sends
-this to `api.typesafe.ai`, under your own TypeSafe account:
-
-- the goal you gave, and your `--fill` names and values
-- the tab's URL and title
-- visible text in the viewport (up to about 6,000 characters)
-- labels, roles and current values of the page's interactive elements
-- the run's last 10 actions
-
-Never sent: password, file and hidden inputs, and nothing at all unless you
-saved a key and ran `reins do`. The extension itself still makes no remote
-requests.
-```
-
-In "What reins does NOT do", change the first bullet to: "No data is sent to the developer. The only remote service reins can talk to is TypeSafe, and only when you've opted in (see below). There is no analytics, telemetry, tracking, or advertising of any kind." Update `_Last updated:_` to today.
-
-- [ ] **Step 2: SECURITY.md.** Add a section before "Hardening checklist":
-
-```md
-## reins do and TypeSafe
-
-`reins do` hands page state to TypeSafe's Jev model, which answers typed
-multiple-choice questions: which operation, and which observed element. Jev
-can only choose among elements reins actually read from the page; its output
-never becomes a selector, coordinate or code. Page text can still try to
-steer it (prompt injection), so:
-
-- A click whose label contains a money, messaging or deletion word (buy, pay,
-  send, delete, …) stops the run unless the agent passed `--confirm` for that
-  label or the goal names it word for word. Unlabeled buttons stop too. This
-  is a heuristic, not a guarantee: other languages and odd labels can slip past.
-- A run that moves to another site stops (`left_site`), and site permissions
-  still apply on every step (`full` required).
-- Ctrl-C, a dead agent, `--timeout` or a daemon restart stop the run before its
-  next action.
-- The key file is `~/.reins/credentials.json` (0600). The key is never
-  returned by any command, never logged, and never sent to a page.
-```
-
-- [ ] **Step 3: CHROME_WEB_STORE.md.** In "Privacy tab (paste-ready)":
-- Append to the single-purpose text: " Optionally, the user can paste an API key for TypeSafe (the service behind `reins do`) into the popup; the extension passes it once to the local daemon, which stores it on the user's machine. The extension never sends it anywhere else."
-- Under the data-usage answers, mark "Authentication information" as handled: "an optional API key the user types in the popup, passed only to the local daemon."
-
-- [ ] **Step 4: Web docs.**
-  - `security.tsx`: add `<H2 id="reins-do">reins do and TypeSafe</H2>` with the same bullets as Step 2, using the file's `P`/`Ul` components. The popup and CLI link to `#reins-do`.
-  - `commands.tsx`, `management` group rows: add `["reins key set|status|clear [typesafe]", "Save, check or remove the TypeSafe key that powers reins do. The key is read without echo and stored in ~/.reins/credentials.json."]`.
-
-- [ ] **Step 5: Changeset.**
-
-```md
----
-"@karnstack/reins": minor
----
-
-`reins key set|status|clear typesafe` stores a TypeSafe API key in `~/.reins/credentials.json` (readable only by you), after checking it with TypeSafe. The extension popup gains a Jev section to save, replace or remove the same key. This is the setup for `reins do`.
-```
-
-- [ ] **Step 6: Verify and commit**
-
-Run: `pnpm lint && pnpm typecheck && pnpm test && pnpm build`
-Expected: PASS.

-  - `actionPoint(selector: string, timeoutMs: number, forClick: boolean, node?: number | null): Promise<ActionPoint>`. When `node` is set, the element is `window[Symbol.for("reins.jev")].nodes.get(node)` instead of `document.querySelector(selector)`, and `selector` is used only in messages.
-  - `actionablePoint(tabId, css, action, forClick, opts?: { node?: number; timeoutMs?: number })`
-  - `pressAt(tabId: number, x: number, y: number, what: string, button?: "left"|"right"|"middle", clickCount?: number): Promise<void>`. It throws `click on <what> landed on <by> instead …` when the probe saw a miss.
-
-- [ ] **Step 1: Write the failing test**
-
-Add to `cdp.test.ts`. Extend its import with `actionablePoint`.
-
-```ts
-describe("actionablePoint for a Jev node", () => {
-  it("passes the node id and the short timeout into the page check", async () => {
-    const sendCommand = vi.fn(async () => ({ result: { value: { x: 5, y: 6 } } }));
-    vi.stubGlobal("chrome", {
-      debugger: { attach: vi.fn(), detach: vi.fn(), onDetach: { addListener: () => {} }, sendCommand },
-    });
-    await expect(
-      actionablePoint(7, "node 12", "click", true, { node: 12, timeoutMs: 500 }),
-    ).resolves.toEqual({ x: 5, y: 6 });
-    const expr = (sendCommand.mock.calls[0] as unknown as [unknown, string, { expression: string }])[2]
-      .expression;
-    expect(expr).toMatch(/\("node 12", 500, true, 12\)$/);
-  });
-});
-```
-
-- [ ] **Step 2: Run to verify fail**
-
-Run: `pnpm --filter @reins/extension test -- cdp`
-Expected: FAIL. The expression ends `, 5000, true)`.
-
-- [ ] **Step 3: Implement**
-
-In `actionability.ts`, change the signature and add a finder. Keep the body self-contained, because it is serialized into the page:
-
-```ts
-export async function actionPoint(
-  selector: string,
-  timeoutMs: number,
-  forClick: boolean,
-  node: number | null = null,
-): Promise<ActionPoint> {
-  // A Jev node id points at the exact element reins do observed; otherwise
-  // the CSS selector is re-queried (frameworks may swap nodes while we wait).
-  const find = (): Element | null => {
-    if (node === null) return document.querySelector(selector);
-    const cache = (window as unknown as Record<symbol, { nodes?: Map<number, Element> } | undefined>)[
-      Symbol.for("reins.jev")
-    ];
-    const el = cache?.nodes?.get(node);
-    return el?.isConnected ? el : null;
-  };
-```
-
-Then replace both uses of `document.querySelector(selector)` in the body (`const el = …` in the loop, and `const now = …` in the probe) with `find()`.
-
-In `cdp.ts`:
-
-```ts
-export async function actionablePoint(
-  tabId: number,
-  css: string,
-  action: string,
-  forClick: boolean,
-  opts: { node?: number; timeoutMs?: number } = {},
-): Promise<{ x: number; y: number }> {
-  const { result } = await send<{
-    result: { value: { x: number; y: number } | { error: string } };
-  }>(tabId, "Runtime.evaluate", {
-    expression: `(${actionPoint})(${JSON.stringify(css)}, ${opts.timeoutMs ?? ACTION_TIMEOUT_MS}, ${forClick}, ${opts.node ?? null})`,
-    returnByValue: true,
-    awaitPromise: true,
-  });
-  // … unchanged below
-}
-
-/**
- * Press at (x, y) and confirm the press reached the element actionablePoint
- * armed the probe on. Only a press seen landing elsewhere fails.
- */
-export async function pressAt(
-  tabId: number,
-  x: number,
-  y: number,
-  what: string,
-  button: "left" | "right" | "middle" = "left",
-  clickCount = 1,
-): Promise<void> {
-  const buttonBit = button === "right" ? 2 : button === "middle" ? 4 : 1;
-  const base = { x, y, button, clickCount };
-  await send(tabId, "Input.dispatchMouseEvent", { type: "mouseMoved", x, y, buttons: 0 });
-  await send(tabId, "Input.dispatchMouseEvent", { type: "mousePressed", ...base, buttons: buttonBit });
-  await send(tabId, "Input.dispatchMouseEvent", { type: "mouseReleased", ...base, buttons: 0 });
-  const probe = await send<{ result: { value: ProbeResult | null } }>(tabId, "Runtime.evaluate", {
-    expression: `(${readProbe})()`,
-    returnByValue: true,
-  }).then(
-    (r) => r.result.value,
-    () => null,
-  );
-  if (probe?.state === "missed") {
-    throw new Error(
-      `click on ${what} landed on ${probe.by} instead — the page changed under the pointer. Re-snapshot and retry.`,
-    );
-  }
-}
-```
-
-Replace the body of `cdpClick` after `actionablePoint` with:
-
-```ts
-    await pressAt(tabId, x, y, css, params.button ?? "left", params.clickCount ?? 1);
-    return { ok: true };
-```
-
-Keep the existing comments about explicit button/count, moving them onto `pressAt`.
-
-- [ ] **Step 4: Run to verify pass**
-
-Run: `pnpm --filter @reins/extension test && pnpm --filter @reins/extension typecheck`
-Expected: PASS. The existing click tests and the real-browser tests (if Chrome is present) stay green.
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add packages/extension/src/lib/actionability.ts packages/extension/src/lib/cdp.ts packages/extension/src/lib/cdp.test.ts

-### Task 11: Extension — Jev page functions (snapshot, check, select, settle)
-
-**Files:**
-- Create: `packages/extension/src/lib/jev-snapshot.ts`
-- Test: `packages/extension/src/lib/pointer.browser.test.ts` (new `jev:` cases in the existing real-browser suite, which reuses its Chrome harness)
-
-**Interfaces:**
-- Produces (all page-side, self-contained, run via `Runtime.evaluate`):
-  - `jevSnapshot(): Omit<JevObservation, "dialog"> | null`. Returns null while the document has no body. Stores node identity and guards under `window[Symbol.for("reins.jev")]`.
-  - `jevCheck(node: number): string`, which is `"ok"` or the reason the target changed
-  - `jevSelect(node: number, value: string): string`, which is `"ok"` or a reason
-  - `jevSettle(node: number | null, typed: boolean): Promise<void>`
-
-- [ ] **Step 1: Implement the page functions**
-
-```ts
-// packages/extension/src/lib/jev-snapshot.ts
-/**
- * Page-side halves of `reins do`. Each runs *inside the page* via
- * Runtime.evaluate, serialized with Function.prototype.toString, so it must
- * stay self-contained: no imports, no references to module scope.
- *
- * Ported from browser-use/jev-ultrafast `snapshot.js` (MIT). Differences: the
- * cache lives under a symbol, not a page global; rects and scroll are left out
- * of the result (the daemon's change check must ignore reins' own
- * scrollIntoView); guards are kept page-side for jevCheck.

-Biome may reflow the multi-item arrays. Run `pnpm format` and accept its layout.
-
-- [ ] **Step 2: Write the real-browser tests**
-
-In `pointer.browser.test.ts`:
-1. Add a fixture constant:
-
-```ts
-const JEV_FIXTURE = `<!doctype html><html><head><meta charset="utf-8"><style>
-  body { margin: 0; font: 14px sans-serif }
-  #modal { position: fixed; bottom: 10px; right: 10px }
-  #hide { display: none }
-</style></head><body>
-<h1>Flights</h1>
-<form id="f">
-  <label for="from">Where from?</label><input id="from" value="San Francisco">
-  <input id="to" aria-label="Where to?">
-  <input id="pw" type="password" aria-label="Password">
-  <input id="h" type="hidden" value="secret">
-  <select id="cabin" aria-label="Cabin"><option value="eco" selected>Economy</option><option value="biz">Business</option></select>
-  <button id="search" type="submit">Search</button>
-</form>
-<button id="off" disabled>Disabled</button>
-<button id="hide">Hidden</button>
-<div style="position:relative"><button id="covered">Covered</button><div style="position:absolute;inset:0"></div></div>
-<button id="swap">Swap me</button>
-<div id="modal" role="dialog"><button id="cookies">Accept cookies</button></div>
-<script>
-  window.__log = [];
-  document.getElementById("cabin").addEventListener("change", (e) => __log.push("change:" + e.target.value));
-  document.getElementById("f").addEventListener("submit", (e) => e.preventDefault());
-</script></body></html>`;
-```
-
-2. Change the server handler to `s.end(q.url === "/login" ? LOGIN_FIXTURE : q.url === "/jev" ? JEV_FIXTURE : FIXTURE);`.
-3. Change `load` to take a path: `async function load(path = "/"): Promise<void> { await cdp("Page.navigate", { url: new URL(path, url).href }); … }`. Existing calls keep working.
-4. Import `jevSnapshot` from `./jev-snapshot.js`.
-5. Add, inside the existing `describe.skipIf(!CHROME)(…)`:
-
-```ts
-  type Snap = NonNullable<ReturnType<typeof jevSnapshot>>;
-  const snap = () => evaluate<Snap>(`(${jevSnapshot})()`);
-  const nodeOf = (s: Snap, label: string) => s.actions.find((a) => a.label === label)?.node;
-
-  it("jev: lists visible controls, including a fixed-position dialog, and skips the rest", async () => {
-    await load("/jev");
-    const s = await snap();
-    const labels = s.actions.map((a) => `${a.kind}:${a.label}`);
-    expect(labels).toContain("fill:Where from?");
-    expect(labels).toContain("fill:Where to?");
-    expect(labels).toContain("click:Accept cookies");
-    expect(labels).toContain("select:Cabin → Business");
-    expect(labels.join()).not.toMatch(/Password|Disabled|Hidden|secret/);
-    expect(s.actions.find((a) => a.label === "Where from?")?.value).toBe("San Francisco");
-    expect(s.text).toContain("Flights");
-  });
-
-  it("jev: a node keeps its id across snapshots", async () => {
-    await load("/jev");
-    const a = nodeOf(await snap(), "Search");
-    const b = nodeOf(await snap(), "Search");
-    expect(a).toBeDefined();
-    expect(a).toBe(b);
-  });
-```
-
-Task 12 adds the act tests, which need `jev.ts`.

-- [ ] **Step 3: Run**
-
-Run: `pnpm --filter @reins/extension test -- pointer.browser && pnpm --filter @reins/extension typecheck && pnpm lint`
-Expected: PASS. If Chrome isn't installed, the suite is skipped; state that in the task report.

-- Test: `packages/extension/src/lib/jev.test.ts`, `packages/extension/src/lib/dispatch.test.ts`, `packages/extension/src/lib/pointer.browser.test.ts`
-
-**Interfaces:**
-- Consumes: `drivePage`, `ensureVisible`, `actionablePoint`, `pressAt`, `resolveTabId`, `send` (cdp.ts, Task 10); the page functions (Task 11); `JevObserveParams`, `JevActParams`, `JevObservation`, `JevActResult` (Task 9)
-- Produces:
-  - `jevObserve(params: JevObserveParams): Promise<JevObservation>`
-  - `jevAct(params: JevActParams): Promise<JevActResult>`
-  - `initDialogTracking(): void`, `openDialog(tabId: number): JevDialog | undefined`
-  - `JEV_ACTION_TIMEOUT_MS = 500`
-
-- [ ] **Step 1: Write the failing unit tests**
-
-```ts
-// packages/extension/src/lib/jev.test.ts
-import { afterEach, describe, expect, it, vi } from "vitest";
-
-vi.mock("./monitor.js", () => ({ isMonitored: () => false }));
-
-import { initDialogTracking, jevObserve, openDialog } from "./jev.js";
-
-afterEach(() => vi.unstubAllGlobals());
-
-function stubChrome() {
-  let onEvent: ((s: { tabId?: number }, m: string, p?: unknown) => void) | undefined;
-  const sendCommand = vi.fn();
-  vi.stubGlobal("chrome", {
-    debugger: {
-      attach: vi.fn(),
-      detach: vi.fn(),
-      sendCommand,
-      onDetach: { addListener: () => {} },
-      onEvent: { addListener: (fn: typeof onEvent) => (onEvent = fn) },
-    },
-  });
-  initDialogTracking();
-  return { fire: (tabId: number, m: string, p?: unknown) => onEvent?.({ tabId }, m, p), sendCommand };
-}
-
-describe("dialog tracking", () => {
-  it("remembers an open dialog until it closes", () => {
-    const { fire } = stubChrome();
-    fire(4, "Page.javascriptDialogOpening", { type: "confirm", message: "Leave?" });
-    expect(openDialog(4)).toEqual({ type: "confirm", message: "Leave?" });
-    fire(4, "Page.javascriptDialogClosed", {});
-    expect(openDialog(4)).toBeUndefined();
-  });
-
-  it("observe reports the dialog without touching the blocked page", async () => {
-    const { fire, sendCommand } = stubChrome();
-    fire(9, "Page.javascriptDialogOpening", { type: "alert", message: "Hi" });
-    const obs = await jevObserve({ tabId: 9 });
-    expect(obs.dialog).toEqual({ type: "alert", message: "Hi" });
-    expect(sendCommand).not.toHaveBeenCalled();
-  });
-});
-```
-
-In `dispatch.test.ts`, add a mock next to the others:
-
-```ts
-vi.mock("./jev.js", () => ({
-  jevObserve: vi.fn(async () => ({ url: "https://x.com/", title: "", text: "", visible: true, actions: [] })),
-  jevAct: vi.fn(async () => ({ ok: true })),
-}));
-```
-
-Then add a test (import `jevAct` from `./jev.js`), following the file's `stubTabs()` pattern:
-
-```ts
-  it("routes jev_act to the handler with the tab pinned", async () => {
-    stubTabs();
-    const out = await dispatchWithMeta("jev_act", { op: "click", node: 3 });
-    expect(out.result).toEqual({ ok: true });
-    expect(jevAct).toHaveBeenCalledWith({ op: "click", node: 3, tabId: 1 });
-    expect(out.meta).toMatchObject({ tabId: 1, host: "x.com" });
-  });
-```

-}
-```
-
-In `dispatch.ts`, import `{ jevAct, jevObserve } from "./jev.js"` and add two cases to `runHandler`:
-
-```ts
-    case "jev_observe":
-      return jevObserve(gated as Parameters<typeof jevObserve>[0]);
-    case "jev_act":
-      return jevAct(gated as Parameters<typeof jevAct>[0]);
-```
-
-- [ ] **Step 4: Add the real-browser act tests**
-
-In `pointer.browser.test.ts`:
-- Import `jevAct` and `jevObserve` from `./jev.js`.
-- Add `onEvent: { addListener: () => {} }` to the stubbed `chrome.debugger`.
-- Add, inside the suite:
-
-```ts
-  it("jev: types over an existing value", async () => {
-    await load("/jev");
-    const s = await jevObserve({ tabId: 1 });
-    const node = s.actions.find((a) => a.label === "Where from?")?.node as number;
-    expect(await jevAct({ tabId: 1, op: "type", node, text: "Zurich" })).toEqual({ ok: true });
-    expect(await evaluate<string>('document.getElementById("from").value')).toBe("Zurich");
-  });
-
-  it("jev: picks a native select option and fires change", async () => {
-    await load("/jev");
-    const s = await jevObserve({ tabId: 1 });
-    const opt = s.actions.find((a) => a.label === "Cabin → Business");
-    expect(await jevAct({ tabId: 1, op: "select", node: opt?.node as number, value: "biz" })).toEqual({ ok: true });
-    expect(await log()).toContain("change:biz");
-  });
-
-  it("jev: a node replaced after the read comes back stale, not clicked", async () => {
-    await load("/jev");
-    const s = await jevObserve({ tabId: 1 });
-    const node = s.actions.find((a) => a.label === "Swap me")?.node as number;
-    await evaluate('document.getElementById("swap").replaceWith(Object.assign(document.createElement("button"), { textContent: "Swap me" }))');
-    const r = await jevAct({ tabId: 1, op: "click", node });
-    expect(r).toMatchObject({ stale: true, reason: "the element is gone" });
-  });
-
-  it("jev: a covered target comes back stale within about half a second", async () => {
-    await load("/jev");
-    const s = await jevObserve({ tabId: 1 });
-    // The snapshot lists it (it is visible); only the act-time hit test sees the overlay.
-    const node = s.actions.find((a) => a.label === "Covered")?.node as number;
-    const t0 = Date.now();
-    expect(await jevAct({ tabId: 1, op: "click", node })).toMatchObject({ stale: true });
-    expect(Date.now() - t0).toBeLessThan(1500);
-  });
-```
-
-- [ ] **Step 5: Run to verify pass**
-
-Run: `pnpm --filter @reins/extension test && pnpm --filter @reins/extension typecheck && pnpm lint`
-Expected: PASS. The browser cases are skipped if there's no Chrome; say so in the report.
-
-- [ ] **Step 6: Manual smoke check (reins opens its own tab)**
-
-```bash
-pnpm build && reins extension --reload && reins restart
-reins open https://en.wikipedia.org/wiki/Main_Page
-reins cdp Runtime.evaluate '{"expression":"1"}'   # sanity: the tab is drivable
-```
-
-Then run `reins eval` on that tab only. `jev_observe` has no CLI yet, so call it through the daemon:
-`curl -s -X POST http://127.0.0.1:$(cat ~/.reins/port)/rpc -H 'content-type: application/json' -d '{"method":"jev_observe","params":{}}' | head -c 600`
-Expected: JSON with `actions` that includes the search box, and `visible: true`.
-
-- [ ] **Step 7: Commit**
-
-```bash
-git add packages/extension/src
-git commit -m "feat(extension): jev_observe and jev_act with dialog tracking

-### Task 16: Daemon — the loop
-
-**Files:**
-- Create: `packages/cli/src/jev/loop.ts`
-- Test: `packages/cli/src/jev/loop.test.ts`
-
-**Interfaces:**
-- Consumes: `buildRequest`, `fillOnlyRequest`, `interpret`, `interpretFill` (Task 13); `riskyReason`, `normalizeLabel`, `sameSite`, `noProgress`, `fingerprint` (Task 14); `RunState`, `DoResult`, `DoStep`, `StepOp` (Task 13); `JevObservation`, `JevActParams`, `JevActResult`, `hostOf` (protocol); `JevAsk` (Task 3)
-- Produces:
-  - `interface LoopDeps { observe(): Promise<JevObservation>; act(p: Omit<JevActParams, "browserId" | "tabId">): Promise<JevActResult>; ask: JevAsk; now(): number }`
-  - `interface LoopInput { run: RunState; maxSteps: number; timeoutMs: number; signal: AbortSignal; continued: boolean; first?: JevObservation }`

-- [ ] **Step 4: Run to verify pass**
-
-Run: `pnpm --filter @karnstack/reins test -- jev/loop && pnpm --filter @karnstack/reins typecheck`
-Expected: PASS.
-
-Two tests depend on ordering, so check these if they fail:
-- "stops at max steps": the budget check happens after deciding and before acting.
-- "stuck": after the 3rd action, the next iteration observes, marks `pageChanged=false`, and `noProgress` fires.

-
-**Files:**
-- Create: `packages/cli/src/jev/do.ts`
-- Modify: `packages/cli/src/rpc.ts` (route `do`), `packages/cli/src/audit.ts` (`outcome` field, `fills` redaction), `packages/cli/src/daemon.ts` (per-request `AbortSignal`, drain on shutdown), `packages/cli/src/serve.ts` (wire `doRun`)
-- Test: `packages/cli/src/jev/do.test.ts`, `packages/cli/src/rpc.test.ts`, `packages/cli/src/audit.test.ts`, `packages/cli/src/daemon.test.ts`
-
-**Interfaces:**
-- Consumes: `runLoop` (Task 16); `RunStore`, `newRun` (Task 15); `nextCommand` (Task 17); `readKey` (Task 2); `createJevAsk`, `JevAsk` (Task 3); `BridgePort` (bridge.ts); `AuditHook`, `redactParams` (audit.ts)
-- Produces:
-  - `DoParams` (zod): `{ browserId?, tabId?, goal?, fills: Record<string,string>, confirms: string[], continue: boolean, maxSteps: number, timeoutSec: number }`
-  - `handleDo(bridge: BridgePort, raw: unknown, ctx: DoContext): Promise<DoResult>`, where `DoContext = { runs: RunStore; credentialsDir: string; signal: AbortSignal; audit?: AuditHook; createAsk?: (key: string) => JevAsk; now?: () => number }`

-  });
-```
-
-`rpc.ts`:
-- Import `type DoResult` from `./jev/types.js`.
-- Add to `RpcContext`: `doRun?: (params: Record<string, unknown>, signal: AbortSignal) => Promise<DoResult>;`.
-- Extend `finish`'s outcome parameter with `outcome?: string` and spread `...(outcome.outcome !== undefined ? { outcome: outcome.outcome } : {})` into the record.
-- In the `try`, after the key branch, add:

-        outcome: `${result.status} · ${result.step} steps · ${result.jevCalls} jev calls`,
-        ...(result.status !== "done" ? { error: new Error(`${result.status}: ${result.reason ?? ""}`) } : {}),
-      });
-      return result;
-    }
-```
-
-Add to `rpc.test.ts`:
-
-```ts
-  it("runs do in the daemon and audits its outcome with fills redacted", async () => {
-    const bridge = fakeBridge();
-    const records: AuditRecord[] = [];
-    const doRun = vi.fn(async () => ({
-      status: "done" as const, steps: [], url: "", title: "", elapsedMs: 1, jevCalls: 3, step: 2, maxSteps: 30, pageChanges: 2,
-    }));
-    const result = await handleRpc(
-      bridge,
-      { method: "do", params: { goal: "g", fills: { from: "Zurich" } } },
-      (r) => records.push(r),
-      { doRun },
-    );
-    expect(result).toMatchObject({ status: "done" });
-    expect(bridge.requestFull).not.toHaveBeenCalled();
-    expect(records[0]).toMatchObject({ method: "do", ok: true, outcome: "done · 2 steps · 3 jev calls" });
-    expect(JSON.stringify(records)).not.toContain("Zurich");
-  });
-```
-
-- [ ] **Step 4: Abort on hang-up and drain on shutdown (`daemon.ts`)**
-
-Replace the `/rpc` and `/shutdown` branches, and add the in-flight set inside `startDaemon` before `createHttpServer`:
-
-```ts
-  /** In-flight /rpc calls: aborted when their CLI hangs up or the daemon stops. */
-  const inflight = new Map<AbortController, Promise<void>>();
-
-  /** Stop active runs before their next action, and give their answers ≤1 s to go out. */
-  async function drain(): Promise<void> {
-    if (inflight.size === 0) return;
-    for (const c of inflight.keys()) c.abort(new Error("daemon restarting"));
-    await Promise.race([
-      Promise.allSettled([...inflight.values()]),
-      new Promise((r) => setTimeout(r, 1000)),
-    ]);
-  }
-```
-
-```ts
-    if (path === "/rpc" && req.method === "POST") {
-      const controller = new AbortController();
-      // res "close" before end = the CLI went away (Ctrl-C, dead agent).
-      res.on("close", () => {
-        if (!res.writableEnded) controller.abort(new Error("the reins CLI went away"));
-      });
-      const done = readJsonBody(req)
-        .then((body) => handleRpc(opts.bridge, body, opts.audit, { ...opts.context, signal: controller.signal }))
-        .then((result) => sendJson(res, 200, { result }))
-        .catch((err) => {
-          const message = err instanceof Error ? err.message : String(err);
-          sendJson(res, err instanceof RpcBadRequest ? 400 : 502, { error: message });
-        })
-        .finally(() => inflight.delete(controller));
-      inflight.set(controller, done);
-      return;
-    }
-    if (path === "/shutdown" && req.method === "POST") {
-      opts.log("reins: shutdown requested over /shutdown");
-      sendJson(res, 200, { ok: true });
-      void drain().then(() => {
-        if (opts.onShutdown) setImmediate(opts.onShutdown);
-      });
-      return;
-    }
-```
-
-Add to `daemon.test.ts`. Use the file's existing startup pattern: a `BridgeHost` with an empty allowlist, and `startDaemon` on port 0.
-
-```ts
-describe("reins do lifecycle", () => {

-    ctrl.abort();
-    await req;
-    await vi.waitFor(() => expect(seen?.aborted).toBe(true));
-    await daemon.close();
-  });
-
-  it("answers an active run with 'daemon restarting' before shutting down", async () => {
-    const onShutdown = vi.fn();

-    const daemon = await startDaemon({
-      port: 0,
-      bridge,
-      log: () => {},
-      onShutdown,
-      context: {

-            ),
-          ),
-      },
-    });
-    const run = fetch(`http://127.0.0.1:${daemon.port}/rpc`, {
-      method: "POST",
-      headers: { "content-type": "application/json" },

-    await vi.waitFor(() => expect(onShutdown).toHaveBeenCalled());
-    await daemon.close();
-  });
-});
-```
-
-`serve.ts`: add `const runs = new RunStore();` and pass
-
-```ts
-      context: {
-        keys,
-        doRun: (params, signal) =>

-### Task 19: CLI — the `reins do` command
-
-**Files:**
-- Modify: `packages/cli/src/commands.ts` (new `do` command; `ToolCommand` gains `timeoutMs` and `exitCode`)
-- Modify: `packages/cli/src/cli.ts` (`rpc()` timeout parameter; exit code)
-- Modify: `packages/cli/src/cli-commands.ts` (help lists `do`)
-- Test: `packages/cli/src/commands.test.ts`
-
-**Interfaces:**
-- Consumes: `formatDoResult` (Task 17); `doExitCode`, `DoResult` (Task 13)
-- Produces:
-  - `ToolCommand.timeoutMs?(params): number`
-  - `ToolCommand.exitCode?(result): number`
-  - `TOOL_COMMANDS.do`
-
-- [ ] **Step 1: Write the failing tests**
-
-Add to `commands.test.ts`. It uses `parseArgs` with the command's `booleans`/`multi`, the same way `runTool` does. Import `parseArgs` from `./args.js` if it isn't already imported.
-
-```ts
-describe("reins do", () => {
-  const cmd = TOOL_COMMANDS.do as ToolCommand;
-  const build = (argv: string[]) =>
-    cmd.build(parseArgs(argv, { booleans: [...(cmd.booleans ?? []), "json"], multi: cmd.multi }));
-
-  it("builds a run from the goal, fills and confirms", () => {
-    expect(
-      build(["one-way", "Zurich", "→", "London", "--fill", "from=Zurich", "--fill=to=London", "--confirm", "Book", "--tab", "7"]),
-    ).toEqual({
-      tabId: 7,
-      goal: "one-way Zurich → London",
-      fills: { from: "Zurich", to: "London" },
-      confirms: ["Book"],
-      continue: false,
-      maxSteps: 30,
-      timeoutSec: 60,
-    });
-  });
-
-  it("--continue needs no goal", () => {
-    expect(build(["--continue", "--fill", "passenger=Ada Lovelace"])).toMatchObject({
-      continue: true,
-      fills: { passenger: "Ada Lovelace" },
-    });
-  });
-
-  it.each([
-    [[], "a goal is required"],
-    [["g", "--fill", "from"], "--fill needs name=value"],
-    [["g", "--fill", "From=Zurich"], "lowercase"],
-    [["g", "--max-steps", "0"], "--max-steps"],
-    [["g", "--timeout", "1"], "--timeout"],
-  ])("rejects %j", (argv, message) => {
-    expect(() => build(argv)).toThrow(message);
-  });
-
-  it("waits longer than the run's own timeout", () => {
-    expect(cmd.timeoutMs?.({ timeoutSec: 60 })).toBe(70_000);
-  });
-
-  it("exits 0 done, 2 handoff, 1 error", () => {

-    expect(cmd.exitCode?.(r("risky_action"))).toBe(2);
-    expect(cmd.exitCode?.(r("error"))).toBe(1);
-  });
-});
-```
-
-- [ ] **Step 2: Run to verify fail**
-
-Run: `pnpm --filter @karnstack/reins test -- commands`
-Expected: FAIL.
-
-- [ ] **Step 3: Implement**
-
-`commands.ts`:
-- Add to the `ToolCommand` interface:
-
-```ts
-  /** How long the CLI waits for the daemon's answer (default 30 s). */
-  timeoutMs?(params: Record<string, unknown>): number;
-  /** Process exit code for a successful call (default 0). */
-  exitCode?(result: unknown): number;
-```
-
-- Add imports `import { formatDoResult } from "./jev/format.js";` and `import { type DoResult, doExitCode } from "./jev/types.js";`.
-- Add helpers near the others:
-
-```ts
-/** Repeatable flag → list (empty when absent). */
-function listFlag(a: ParsedArgs, name: string): string[] {
-  const v = a.flags[name];
-  if (v === undefined) return [];
-  return (Array.isArray(v) ? v : [v]).map(String);
-}
-
-/** Repeatable --fill name=value → { name: value }. */
-function parseFills(a: ParsedArgs): Record<string, string> {
-  const fills: Record<string, string> = {};
-  for (const raw of listFlag(a, "fill")) {
-    const eq = raw.indexOf("=");
-    if (eq <= 0) throw new UsageError(`--fill needs name=value, got "${raw}"`);
-    const name = raw.slice(0, eq);
-    if (!/^[a-z0-9_-]+$/.test(name)) {
-      throw new UsageError(`--fill names are lowercase letters, digits, _ or -, got "${name}"`);
-    }
-    fills[name] = raw.slice(eq + 1);
-  }
-  return fills;
-}
-```
-
-- Add the command to `TOOL_COMMANDS`, before `snapshot`:
-
-```ts
-  do: {
-    method: "do",
-    usage:
-      'reins do "<goal>" [--fill name=value]... [--confirm "<label>"]... [--continue] [--max-steps 30] [--timeout 60] [--tab <id>]',
-    summary: "hand a small task to Jev: it clicks and types until done (needs `reins key set typesafe`)",
-    booleans: ["continue"],
-    multi: ["fill", "confirm"],
-    build: (a) => {
-      const goal = a.positional.join(" ").trim();
-      const cont = a.flags.continue === true;
-      if (!goal && !cont) throw new UsageError('a goal is required: reins do "<goal>"');
-      const maxSteps = flagInt(a, "max-steps") ?? 30;
-      if (maxSteps < 1 || maxSteps > 200) throw new UsageError("--max-steps must be 1–200");
-      const timeoutSec = flagInt(a, "timeout") ?? 60;
-      if (timeoutSec < 5 || timeoutSec > 600) throw new UsageError("--timeout must be 5–600 seconds");
-      return {
-        ...base(a),
-        ...(goal ? { goal } : {}),
-        fills: parseFills(a),
-        confirms: listFlag(a, "confirm"),
-        continue: cont,
-        maxSteps,
-        timeoutSec,
-      };
-    },
-    timeoutMs: (p) => (Number(p.timeoutSec ?? 60) + 10) * 1000,
-    exitCode: (r) => doExitCode(r as DoResult),
-    format: (r) => formatDoResult(r as DoResult),
-  },
-```
-
-`cli.ts`:
-- Change `rpc` to take `timeoutMs = 30_000` as a 4th parameter and use `AbortSignal.timeout(timeoutMs)`.
-- In `runTool`, call `rpc(ensured.port, cmd.methodFor?.(params) ?? cmd.method, params, cmd.timeoutMs?.(params))`.
-- Before each `return`/end of `runTool` (after printing, in both the `--json` branch and the formatted branch), set:
-
-```ts
-  const code = cmd.exitCode?.(result) ?? 0;
-  if (code !== 0) process.exitCode = code;
-```
-
-`cli-commands.ts`: in `helpText`, add a section before `Tabs & pages:`:
-
-```ts
-    "Delegate:",
-    tool("do"),
-    "",
-```
-
-- [ ] **Step 4: Run to verify pass**
-
-Run: `pnpm --filter @karnstack/reins test && pnpm --filter @karnstack/reins typecheck && pnpm lint`
-Expected: PASS.
-
-- [ ] **Step 5: End-to-end check (real key, a tab reins opened)**
-
-```bash
-pnpm build && reins extension --reload && reins restart
-reins key status                       # typesafe: set (••••xxxx)
-reins open https://en.wikipedia.org/wiki/Main_Page
-reins do "Find and open the Wikipedia article about Gödel's incompleteness theorems" --fill query="Gödel's incompleteness theorems"
-echo "exit $?"
-reins text | head -5                   # verify independently
-```
-
-Expected: `done in …s`, exit 0, and `reins text` shows the article. Then run a handoff check: on a page with a "Delete" button (use the jev fixture served locally, or any page reins opened), confirm `risky_action` prints the `--confirm` next line and exits 2.

-### Task 20: Skill, web docs, changeset
-
-**Files:**
-- Modify: `skills/reins/SKILL.md`
-- Modify: `packages/web/src/routes/docs/commands.tsx`
-- Create: `.changeset/reins-do.md`
-
-- [ ] **Step 1: Skill.** In `skills/reins/SKILL.md`, add a section after "Core loop":
-
-```md
-## Delegate a whole task: `reins do` (when a TypeSafe key is set)
-
-For a multi-step form, search, filter or navigation task, hand it over instead
-of snapshot → click → snapshot. It's much faster: Jev picks each action in
-~0.2 s, and you only think twice.
-
-    reins do "one-way flights Zurich → London, Sep 20 2026, 1 adult; stop when results show" \
-      --fill from=Zurich --fill to=London
-
-- Pass **every value the goal mentions** as `--fill name=value`. Jev picks which
-  field gets which value; it never invents text.
-- If the user already asked for the final action (book, send, pay), pre-approve
-  it: `--confirm "Book"`. Otherwise risky clicks stop the run.
-- Exit 0 = `done`. **DONE is Jev's opinion — always verify** with
-  `reins snapshot` / `reins text`.
-- Exit 2 = a stop. Run the printed `next:` line exactly (usually
-  `reins do --continue …`). `--continue` resumes the same run.
-- `stuck` or `blocked` → switch to manual commands for that part.
-- The risky-label stop is a heuristic (English words; unlabeled buttons stop).
-  Don't rely on it for anything you wouldn't do yourself.
-- No key (`reins do` says so)? Ask the user to run `reins key set typesafe`
-  themselves. Never ask them to paste a key into the chat.
-```
-
-- [ ] **Step 2: Web docs.** In `commands.tsx`, add a group before `tabs`:
-
-```ts
-  {
-    id: "delegate",
-    title: "Delegate",
-    intro:
-      "reins do hands a small task to TypeSafe's Jev model, which picks each click and field in about 0.2 s. The agent supplies every typed value and verifies the result. Needs a TypeSafe key (reins key set typesafe).",
-    rows: [
-      [
-        'reins do "<goal>" [--fill name=value]… [--confirm "<label>"]… [--max-steps 30] [--timeout 60]',
-        "Run the task. Exit 0 when Jev says done (verify it), 2 when it stops for input, 1 on error. Every stop prints the exact next command.",
-      ],
-      [
-        "reins do --continue [--fill …] [--confirm …]",
-        "Resume the tab's last run with the missing value or approval. Runs are remembered for 15 minutes.",
-      ],
-    ],
-  },
-```
-
-- [ ] **Step 3: Changeset**
-
-```md
----
-"@karnstack/reins": minor
----
-
-`reins do "<goal>"` hands a small browser task to TypeSafe's Jev model: it reads the page, picks each click, field and dropdown in about 0.2 s, and types only the values the agent passed with `--fill`. It stops and prints the exact next command for risky clicks (buy, send, delete, …), missing values, dialogs, leaving the site, or no progress. `--continue` resumes the run, and `--confirm "<label>"` pre-approves a click. Exit codes: 0 done, 2 stopped for input, 1 error. The extension gains `jev_observe`/`jev_act` (site tier `full`).

-Check `reins open`'s actual output format before relying on the `\d+` parse, and adjust `openTab` to it. Check `reins close --tab` versus `reins close <id>` the same way (see `TOOL_COMMANDS.close.usage`).
-
-- [ ] **Step 2: Run it (paid, with the user's go-ahead)**
-
-Tell the user the expected cost first: roughly 4 tasks × 5 runs × 20 Jev calls, plus the Claude arm. Then run: `node packages/cli/scripts/bench-do.mjs 5`
-Expected: a per-task table. Compare it with the ship bar: `reins do` verified success ≥ manual on every task, and median verified time ≥ 3× faster.
-
-- [ ] **Step 3: Write up the results**
-
-Put the table, the environment (browser, network, SDK and model version from a response), the failures, and the verdict against the ship bar in `docs/benchmarks/2026-09-reins-do.md`. Use no marketing language, and state the task count and run count plainly.
-
-- [ ] **Step 4: Commit and open PR3**
-
-```bash
-git add packages/cli/scripts/bench-do.mjs docs/benchmarks/2026-09-reins-do.md
-git commit -m "chore: reins do benchmark script and first results
-
-Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>"
-```
-
-Open PR3 (`feat/reins-do-loop` → `feat/reins-do-extension`), with the benchmark table in the description.

-# reins CLI + skill design (MCP removed)
-
-Date: 2026-07-04
-Status: shipped. Canonical design doc for reins. The architecture below —
-CLI + local daemon (port discovery, multi-browser roster) + MV3 extension
-over a WebSocket bridge — is what the code implements; earlier MCP-era design
-notes have been retired.
-
-## Decision
-
-Drop the MCP server. reins becomes a **CLI-first browser-control tool**
-taught to agents through a **skill** instead of registered with each agent as
-an MCP server:
-
-```
-before   agent ── MCP HTTP ──► daemon ── WS ──► extension        (+ reins install per agent)
-after    agent ── shell ──► reins CLI ── HTTP /rpc ──► daemon ── WS ──► extension
-```
-
-The daemon cannot be removed — extensions cannot listen on sockets, so a
-local rendezvous process must hold the WebSocket — but it shrinks to a thin
-bridge + JSON-RPC endpoint, and its lifecycle becomes invisible: the CLI
-auto-spawns it on demand. OS service management (launchd/systemd) is deleted.
-
-User setup becomes:
-
-```bash
-npm i -g @karnstack/reins        # CLI (daemon inside, auto-spawns on first use)
-npx skills add karnstack/reins   # skill → Claude Code, Cursor, Codex, Copilot, …
-# + reins extension in the browser(s) → connects on its own
-```
-
-No `reins up`, no `reins install <agent>`, no per-agent registration.
-
-## What is removed
-
-- `@modelcontextprotocol/sdk` dependency, `/mcp` endpoint, session handling.
-- `create-server.ts` MCP tool definitions (the `listAllTabs` aggregation and
-  the `browserId` routing move into the daemon's `/rpc` handler).
-- `serve --stdio` mode.
-- `service.ts` (launchd/systemd), `reins up|down|restart`.
-- `reins install claude|codex` and the snippet builders in `cli-commands.ts`.
-- `/browsers` and `/tabs` HTTP endpoints (CLI uses `/health` for the roster
-  and `/rpc list_tabs` for tabs).
-
-Migration for existing MCP registrations: `claude mcp remove reins` (one-off;
-pre-launch, no external users).
-
-## Daemon (kept, shrunk)
-
-Everything from the daemon spec stays except the MCP layer:
-
-- Binds `127.0.0.1`, sticky port (`~/.reins/port`) + walk 8765–8774,
-  `REINS_PORT` pins exact. Logs to `~/.reins/logs/daemon-<date>.log`
-  (renamed from `mcp-<date>.log` with the package move).
-- WS upgrade for the extension, exact `chrome-extension://<id>` origin
-  allowlist (`reins allow <id>` for dev builds, `PUBLISHED_EXTENSION_IDS`
-  baked in).
-- **Host-header validation on every route** (DNS-rebinding defense) — `/rpc`
-  is exactly the kind of endpoint it protects.
-
-Endpoints:
-
-- `GET /health` → `{ ok, version, paired, browsers }` (unchanged).
-- `POST /rpc` → body `{ method: string, params?: object }`; `params` may
-  carry `browserId`, which the daemon splits off for routing (same rule as
-  today: explicit id / single browser / ambiguity error listing the roster).
-  `list_tabs` is special-cased to aggregate across all connected browsers and
-  tag each tab with `browserId`/`browser`. Replies
-  `200 { result }` or `502 { error }` (bridge/tool errors) /
-  `400 { error }` (malformed body).
-- `POST /shutdown` → daemon closes cleanly, replies `200 { ok: true }`.
-
-Run modes:
-
-- `reins daemon` — foreground (the only way the daemon runs; listed under an
-  "advanced" section of help). `serve.ts` becomes this command's runner.
-- Lazy spawn — every CLI command that needs the daemon first probes the
-  candidate ports for `/health`; if none answers, it spawns
-  `process.execPath cli.js daemon` detached (`stdio: "ignore"`, `unref()`;
-  the daemon writes its own log file), then polls `/health` until it answers
-  (timeout ~3 s → error pointing at `reins logs`).
-
-Singleton guard (two CLI invocations racing to spawn): after binding, the
-daemon probes the other candidate ports; if another live daemon answers on a
-**lower** port, it logs and exits — deterministic: the lower-port daemon
-always wins, at most one survives.
-
-Browser-wait UX: if this CLI invocation just spawned the daemon, tool
-commands wait up to 15 s for the first browser to appear in `/health` (the
-extension's reconnect backoff caps at 10 s). If the daemon was already
-running with zero browsers, fail fast:
-`no browser connected — is the reins extension installed? (reins status)`.
-
-Windows side effect: lazy spawn works there too (`detached` +
-`windowsHide`), so Windows moves from "unsupported (no service)" to
-best-effort supported.
-
-## CLI surface
-
-Zero-dependency flag parser (small hand-rolled `parseArgs` helper, unit
-tested). Global flags on every tool command: `--browser <id>` (only needed
-with >1 browser), `--tab <id>` (defaults to the active tab), `--json` (raw
-result JSON; default output is compact readable text). Errors go to stderr,
-exit code 1.
-
-### Tool commands (existing bridge methods)
-
-| Command | Bridge method | Notes |
-|---|---|---|
-| `reins tabs` | `list_tabs` | aggregated, `b1:12 ✓ Title — url` lines |
-| `reins open <url> [--background]` | `open_tab` | prints new tab id |
-| `reins close --tab <id>` | `close_tab` | |
-| `reins focus --tab <id>` | `select_tab` | |
-| `reins nav <url\|back\|forward\|reload>` | `navigate` | prints final URL |
-| `reins snapshot [--mode a11y\|dom\|text] [--max-chars N]` | `read_snapshot` | content + ref list |
-| `reins click (--ref e5 \| --selector css) [--button right\|middle] [--count 2]` | `click` | button/count already in schema |
-| `reins type (--ref \| --selector) --text "…" [--enter]` | `type` | `--enter` → `submit: true` |
-| `reins screenshot [--full] [--format jpeg] [--out path]` | `screenshot` | CLI decodes base64, writes file (default `~/.reins/shots/<ts>.png`), prints absolute path — agent Reads it |
-| `reins eval '<js>' [--await]` | `eval_js` | prints value as JSON |
-| `reins wait (--ref \| --selector) [--state visible\|hidden\|present] [--timeout ms]` | `wait_for` | |
-| `reins console [--since ms] [--level error --level warn]` | `read_console` | one line per entry |
-| `reins network [--since ms] [--url pattern]` | `read_network` | one line per entry |
-
-### Tool commands (new bridge methods)
-
-| Command | New bridge method | Extension implementation |
-|---|---|---|
-| `reins press --key "Escape"` | `press_key` | `Input.dispatchKeyEvent`; key spec `[Meta+\|Ctrl+\|Alt+\|Shift+]<Key>`, mapping table for Enter/Escape/Tab/Arrow*/Backspace/Delete/Home/End/PageUp/PageDown + printable chars |
-| `reins hover (--ref \| --selector)` | `hover` | resolve node → scrollIntoView → `Input.dispatchMouseEvent` mousemove at center |
-| `reins scroll [--ref \| --selector \| --by dx,dy \| --to top\|bottom]` | `scroll` | `Runtime.evaluate`: `scrollIntoView` / `window.scrollBy` / scroll to edge |
-| `reins fill (--ref \| --selector) --value "…"` | `fill` | focus node, set value via native setter (React-compatible), dispatch `input`+`change` |
-| `reins select (--ref \| --selector) --value "…"` | `select_option` | set `<select>` value, dispatch `change` |
-| `reins upload (--ref \| --selector) --file <path> [--file <path>…]` | `upload` | `DOM.setFileInputFiles` (CLI resolves paths to absolute first) |
-| `reins text [--ref \| --selector] [--max-chars N]` | `read_text` | `innerText` of element or `document.body`, truncated — the "read the page" primitive (snapshot only lists interactive elements) |
-| `reins resize --width 1280 --height 800` | `resize` | `chrome.windows.update` on the tab's window — real window resize. (CDP emulation overrides reset when the debugger detaches, so `Emulation.*` stays behind `reins cdp` with that caveat noted in the skill.) |
-| `reins dialog (--accept \| --dismiss) [--text "…"]` | `handle_dialog` | `Page.handleJavaScriptDialog` on the open dialog; error if none open |
-| `reins cdp <Domain.method> [json-params]` | `cdp` | raw `chrome.debugger.sendCommand` passthrough — the escape hatch that makes the surface "basically CDP": drag, cookies, geolocation, PDF, tracing, … |
-
-All new methods get zod param/result schemas in `@reins/protocol` alongside
-the existing ones (same `browserId`/`tabId` optional fields), handlers in the
-extension (`dispatch.ts` cases + lib functions), and unit tests on both
-sides.
-
-`cdp` and `eval` are documented as the same trust domain as today: local,
-user-installed, the debugger banner shows while attached, the popover's
-Disconnect is the kill switch. No new security surface beyond what `eval_js`
-already grants.
-
-### Management commands
-
-```
-browsers   roster from /health          allow <id>   allowlist a dev extension id
-status     daemon + browsers summary    kill         POST /shutdown to the live daemon
-doctor     diagnostics                  daemon       run the daemon in the foreground
-logs       tail newest log              version / help
-```
-
-## Skill
-
-`skills/reins/SKILL.md` at the repo root — the skills.sh convention
-(`skills/<name>/SKILL.md`, one level deep), so
-`npx skills add karnstack/reins` discovers and installs it across supported
-agents (Claude Code, Cursor, Codex, Copilot, Windsurf, Gemini, Cline, …).
-
-Frontmatter:
-
-```yaml
----
-name: reins
-description: Control the user's real, logged-in browser from the shell — list tabs, click, type, screenshot, read pages, run JS and raw CDP — via the reins CLI. Use when asked to interact with, test, or scrape a live webpage in the user's browser.
----
-```
-
-Body (lean — agents read the whole file): prerequisite check
-(`reins status`, install hint if missing), the core loop (`tabs` →
-`snapshot` → act on `--ref` → verify with `text`/`screenshot`), command
-reference, multi-browser (`--browser` from `tabs` output), dialogs,
-`eval`/`cdp` escape hatches, troubleshooting (`doctor`, `logs`,
-`allow <id>`). No versioned install steps — the skill assumes the CLI is on
-PATH and says how to get it if not.
-
-## Repo changes
-
-- `packages/mcp` → **`packages/cli`** (npm name stays `@karnstack/reins`,
-  bin stays `reins`). Root scripts: `pnpm reins <cmd>` stays; `pnpm mcp`
-  becomes `pnpm daemon` (foreground daemon).
-- `skills/reins/SKILL.md` added.
-- Extension: code untouched except popup hint copy (drop `reins up`,
-  reference `reins status` / `reins allow`).
-- Docs rewritten (README, RUNNING, PUBLISHING, PRIVACY): pitch shifts from
-  "MCP server" to "browser skill for any agent"; PUBLISHING gains the
-  skills.sh note (no registration — installable from the repo path as soon
-  as it's public); PRIVACY rewords "MCP daemon" → "local daemon installed by
-  the reins CLI".
-
-## Testing
-
-- Protocol: schema tests for the 10 new methods.
-- Extension: unit tests per new lib handler (key mapping, fill event
-  sequence, scroll modes, dialog, cdp passthrough) via the existing mocked
-  `chrome.debugger` harness.
-- Daemon: `/rpc` happy path, unknown method, `browserId` routing/ambiguity,
-  forged-Host 403 on `/rpc` and `/shutdown` (raw `node:http` with
-  `setHost: false` — `fetch` drops forged Host silently), shutdown behavior,
-  singleton guard (lower port wins).
-- CLI: parser unit tests; command→rpc mapping tests (pure builders in
-  `cli-commands.ts`); lazy-spawn logic with injected spawn/probe fakes.
-- Integration: daemon + fake extension WS + real `/rpc` calls end-to-end.
-
-## Out of scope
-
-- Persistent daemon across reboots (lazy spawn makes it unnecessary; a
-  service can return later if anyone asks).
-- Wrapping more CDP domains as curated commands — `reins cdp` covers the
-  long tail; promote a method to a curated command only when usage shows
-  demand.
-- skills.sh leaderboard mechanics (telemetry-driven; nothing to do on our
-  side beyond the repo layout).

-# Sideload install path (no Chrome Web Store)
-
-**Date:** 2026-07-06
-**Status:** approved
-
-## Problem
-
-The reins extension is pending Chrome Web Store review. Review can stall or
-fail (the `debugger` permission guarantees manual review). Users need a
-supported way to install the extension that does not depend on the store —
-both as a launch fallback and as a permanent option for people who prefer it.
-
-Outside the store, the only viable path for regular users is Chrome's
-**load unpacked** (CRX sideloading is enterprise-policy-only on Windows/Mac).
-The from-source flow in [RUNNING.md](../../RUNNING.md) already works but
-requires a repo checkout, a build, and a per-machine `reins allow` step.
-
-## Design
-
-CLI-managed sideload: the npm package carries the built extension; one command
-stages it for load-unpacked; a pinned key makes its ID stable and
-pre-allowlisted, so there is no `reins allow` step.
-
-### Identity: pinned key
-
-- A one-time RSA keypair was generated offline. Only the **public key** enters
-  the repo (`packages/cli/sideload-key.json`); it is not a secret. The private
-  key is never needed for load-unpacked installs and is archived off-repo.
-- The public key is injected as the `"key"` field of the bundled build's
-  `manifest.json`. Chrome derives the extension ID from it, so the sideloaded
-  extension has the **same ID on every machine**: it ships in the CLI's
-  built-in allowlist next to `PUBLISHED_EXTENSION_IDS`.
-- The store zip (`pnpm zip`, release.yml) is untouched — no `key` field (the
-  store rejects uploads that contain one).
-
-Threat-model note: any *unpacked* extension can copy a public key and claim
-its ID — true for the store build's key too (it is visible in installed
-manifests). Users who enable developer mode and load a malicious unpacked
-extension are already compromised; store-installed extensions still cannot
-forge IDs. No change to the existing security posture.
-
-### Packaging
-
-- `packages/cli/scripts/bundle-extension.mjs` copies
-  `packages/extension/dist/` → `packages/cli/extension/` and injects the
-  `key` into that copy's `manifest.json`. It runs after `tsdown` in the CLI's
-  `build` and `prepack` scripts.
-- `packages/cli/package.json` gains `files: ["dist", "extension"]` and a
-  `@reins/extension` devDependency so turbo builds the extension first.
-- `packages/cli/extension/` is generated output — gitignored, added to the
-  turbo `build` outputs.
-
-### CLI command: `reins extension`
-
-- Extracts the bundled dir to `~/.reins/extension/` (delete + copy — the path
-  is **fixed** so the load-unpacked registration never breaks; hashed chunk
-  files from old versions do not accumulate).
-- Prints numbered steps: open `chrome://extensions` → enable Developer mode →
-  Load unpacked → select `~/.reins/extension`. On re-run (CLI upgrade) the
-  same output notes clicking ⟳ Reload on the extension card.
-- In a source checkout without the bundle, fails with a message pointing at
-  RUNNING.md.
-
-### Docs
-
-- New `docs/SIDELOAD.md`: user-facing walkthrough (npm install → `reins
-  extension` → load unpacked → verify with `reins status`), the update story
-  (re-run + Reload after CLI upgrades), and the dev-mode caveats.
-- README Install section: one line offering the no-store path.
-- `reins help`: `extension` listed under Management.
-
-### Out of scope / future
-
-- Extension-version drift detection (`BrowserInfo` carries no extension
-  version today; a handshake field + `doctor` warning is a follow-up).
-- Auto-opening `chrome://extensions` (not reachable from a CLI).
-- Website docs page for sideloading.
-
-## Testing
-
-- Unit: extension ID derived from the committed public key
-  (sha256(SPKI DER) → first 16 bytes → a–p alphabet) equals the committed ID;
-  `loadAllowedOrigins` includes the sideload origin with no allow-file.
-- Unit: `extractExtension` copies a tree, removes stale files from a previous
-  extract, and throws when the source bundle is missing.
-- Existing suites unchanged; `pnpm lint && pnpm typecheck && pnpm test &&
-  pnpm build` green.

-# Audit log (`reins audit`) — design
-
-Date: 2026-07-11. Status: approved. Roadmap: Phase 1 (v0.3) — "Trust: a
-permission model", audit-log slice. SECURITY.md and the SKILL.md hardening
-pass are the remaining Phase 1 slices, out of scope here.
-
-## Goal
-
-A first-class, structured per-action trail: every browser command reins
-executes — and every one the policy blocks — leaves one line the user can
-review with `reins audit`. The trail answers "what did the agent touch in my
-browser?" for trust review and carries enough detail (redacted params,
-outcome, duration) to debug agent runs.
-
-## Decisions (settled during brainstorming)
-
-| Question | Decision |
-| --- | --- |
-| Audience | Trust review and debugging, equally: full JSONL on disk, `reins audit` renders the trust view |
-| Sensitive params | Redact value-bearing fields before write; plaintext secrets never touch disk |
-| Retention | Daily files, daemon prunes >30 days on startup |
-| Origin source | Extension stamps `host` + `tier` on responses (approach B); daemon composes the record |
-| Writer | Daemon only — single writer, viewer works without a live browser |
-
-## Record format
-
-One JSON line per `/rpc` call, appended to
-`~/.reins/logs/audit-YYYY-MM-DD.jsonl` (same directory as daemon logs — the
-roadmap's "make the action trail first-class where `~/.reins/logs` already
-lives"):
-
-```json
-{"ts":"2026-07-11T10:15:02.113Z","method":"click","browserId":"b1","browser":"Chromium","tabId":412,"host":"app.example.com","tier":"full","params":{"selector":"#submit"},"ok":true,"ms":184}
-{"ts":"2026-07-11T10:15:09.442Z","method":"fill","browserId":"b1","browser":"Chromium","tabId":412,"host":"bank.com","tier":"read","params":{"selector":"#amount","value":"[redacted 7 chars]"},"ok":false,"denied":true,"error":"policy_denied: blocked by policy: bank.com is read-only — grant full access from the reins extension popup","ms":12}
-```
-
-Fields:
-
-- `ts` — ISO 8601, daemon clock, time the request was received.
-- `method` — bridge method name (`click`, `read_text`, …).
-- `browserId` / `browser` — routing id + browser name from the bridge
-  roster; absent when the request failed before reaching a browser.
-- `tabId` — the tab the action actually hit: from response `meta` (the
-  extension gate resolves the active tab when the caller omits `--tab`),
-  falling back to params.
-- `host` / `tier` — stamped by the extension via response `meta` (see
-  below); absent on daemon-side failures or with an older extension.
-- `params` — redacted copy (see Redaction).
-- `ok` — mirror of the response frame.
-- `denied` — `true` only for policy denials (error code `policy_denied`).
-- `error` — `code: message` string when `ok` is false.
-- `ms` — wall-clock duration from send to settle.
-
-`list_tabs` (a daemon-side aggregate across browsers) audits as one line
-with no `host`. Daemon-side failures — timeout, no browser connected,
-disconnect mid-flight — audit with `ok: false` and the error; the trail must
-show attempts, not just completions.
-
-## Redaction
-
-Redaction happens in the daemon **before** the write; plaintext never
-reaches disk. A fixed field-name list, not heuristics:
-
-- `text`, `value`, `expression`, `promptText` → `"[redacted <n> chars]"`.
-- `upload` file paths (`files`) → basename only.
-- `cdp` nested `params` → `"[redacted]"` (arbitrary CDP payloads can carry
-  anything, e.g. `Input.insertText`); the `Domain.method` name stays.
-- Everything else — selectors, URLs, tabIds, key names (`Enter`), scroll
-  deltas — passes through verbatim.
-
-The list lives in one exported table in the CLI package with a table-driven
-test, so adding a future value-bearing param means one row + one test case.
-
-## Data flow
-
-1. **Protocol.** `ResponseFrame` gains an optional
-   `meta: { host?: string, tier?: Tier, tabId?: number }`. Optional means
-   old extensions remain compatible — their records simply lack the fields.
-2. **Extension.** `gate()` in `dispatch.ts` already resolves the target
-   tab (including the active-tab default), its host, and the effective
-   tier. Dispatch returns them alongside the result, and the background
-   stamps `meta` on the response frame for both the success path and the
-   policy-denial path — denials must carry the host so the trail shows
-   what was blocked, not just what ran.
-3. **Denial classification.** Policy denials already carry the structured
-   error code `policy_denied` (the extension's `PolicyDenied` class; the
-   code survives to the ResponseFrame). The daemon auditor classifies
-   `denied: true` off that code — no string matching, no new code needed.
-4. **Daemon auditor.** The `/rpc` handler wraps the bridge call: capture
-   start time, method, redacted params, resolve browser name from the
-   roster; on settle (success or error) append the record. The auditor is
-   injected into `startDaemon` like `log` is, so tests can capture records
-   in memory.
-
-## `reins audit` viewer
-
-Reads the JSONL files directly — no daemon required.
-
-- **Default:** today's records as a table:
-  `HH:MM:SS  method  browser  host  tab  outcome  ms`. Policy denials render
-  `DENIED`; other failures `error`.
-- `--last <n>` — last N records, newest last, crossing day-file boundaries
-  (the repo's flag parser handles `--flag` forms only, so no short `-n`).
-- `--denied` — denials only.
-- `--json` — raw JSONL lines (composable with `--last`/`--denied`).
-- Missing host/tier (old extension, daemon-side failure) renders `—`.
-- Corrupt or partially-written lines are skipped; the viewer prints a
-  one-line skip count to stderr.
-- `reins help` gains an `audit` line under Management.
-
-## Retention
-
-On daemon startup, delete `audit-*.jsonl` whose filename date is older than
-30 days. Filename-based, not mtime — deterministic and testable. Daemon
-`daemon-*.log` files are untouched (candidate for the same policy later,
-separate change).
-
-## Error handling
-
-- Audit writes are best-effort, matching `createLogger`: a full disk or bad
-  permissions must never fail the user's browsing command. First write
-  failure logs a warning to the daemon log/stderr. The trade-off (trail can
-  have gaps under disk pressure) gets documented in SECURITY.md (next Phase
-  1 slice).
-- The auditor never throws into the RPC path; a serialization bug in the
-  auditor must not break `/rpc`.
-
-## Testing
-
-- **protocol:** `ResponseFrame` round-trips `meta`; absent `meta` still
-  parses (back-compat).
-- **extension:** dispatch stamps `meta.host`/`meta.tier`/`meta.tabId` on
-  success and on policy denial (tabId as resolved by the gate, including
-  the active-tab default); denial error code is `policy_denied`.
-- **cli:** table-driven redaction tests; auditor unit tests (denial
-  classification, duration, daemon-side failure records, browser-name
-  resolution); viewer tests (parse, `--last` across files, `--denied`,
-  corrupt lines); prune-on-startup test; end-to-end record via the stand-in WS
-  extension in `integration.test.ts`.
-- Build note: rebuild `@reins/protocol` before running cli/extension tests
-  (workspace consumes `dist/`).
-
-## Out of scope
-
-- Popup/audit UI in the extension — the popup stays a status light and
-  permissions manager.
-- SKILL.md changes — the audit trail is for the user, not the agent.
-- Web docs get a short section (permissions page sibling) in the same PR;
-  the full threat-model treatment lands with SECURITY.md.

-# Permission model (site policy + read-only tiers) — design
-
-Date: 2026-07-11. Status: approved. Roadmap: Phase 1 (v0.3) — "Trust: a
-permission model". This spec unifies the roadmap's "site policy" and
-"read-only mode" bullets into one policy model. Audit log, SECURITY.md, and
-the full SKILL.md hardening pass are separate Phase 1 slices, out of scope
-here.
-
-## Goal
-
-Contain reins' blast radius per site. Today the extension is all-or-nothing:
-connected means every tab, every origin, cookies included. After this change,
-each host resolves to a tier — `deny`, `read`, or `full` — enforced inside
-the extension, the one place a local process can't fake. Grants (loosening)
-happen only through the extension popup, a user gesture the agent cannot
-perform from the shell.
-
-Shipped default preserves today's zero-config behavior: `full` everywhere.
-The policy model is opt-in hardening.
-
-## Decisions (settled during brainstorming)
-
-| Question | Decision |
-| --- | --- |
-| Scope | Site policy + read-only as one unified model |
-| Tiers | 3: `deny` < `read` < `full` |
-| Rule granularity | Host or `*.wildcard` (Chrome match-pattern style) |
-| Shipped default | `full` everywhere (today's behavior) |
-| Grant path | Popup-only; CLI can view + tighten, never loosen |
-| Architecture | Extension-owned: policy in `chrome.storage.local`, enforced in dispatch |
-
-## Policy model
-
-```ts
-// @reins/protocol
-type Tier = "deny" | "read" | "full"; // ordered: deny < read < full
-
-interface PolicyRule {
-  pattern: string; // "github.com" | "*.google.com"
-  tier: Tier;
-}
-
-interface Policy {
-  defaultTier: Tier; // shipped default: "full"
-  rules: PolicyRule[];
-}
-```
-
-- **Storage.** `chrome.storage.local`, key `reinsPolicy`, per browser
-  profile. Multi-browser setups get independent policies by construction —
-  intended (work profile locked down, scratch profile open).
-- **Matching precedence.** Exact host beats wildcard; longest wildcard
-  suffix beats shorter; otherwise `defaultTier`. `*.foo.com` matches
-  subdomains **and** the apex `foo.com` (Chrome match-pattern convention).
-- **Scheme handling.** Rules match http(s) hosts. Tabs with non-http(s) or
-  unparseable URLs (chrome://, about:blank, extension pages) are governed by
-  `defaultTier` only.
-- **Pattern validation.** Bare host or a single leading `*.`; `*` anywhere
-  else is rejected. Input normalized: lowercased, scheme and port stripped.
-
-## Method classification
-
-Lives in `@reins/protocol` as `Record<Method, Tier>` keyed by the method
-union type, so an unclassified new method is a compile error, not a silent
-policy hole.
-
-| Required tier | Methods |
-| --- | --- |
-| `read` | `list_tabs`, `read_snapshot`, `read_text`, `screenshot`, `read_console`, `read_network`, `wait_for` |
-| `full` | `navigate`, `open_tab`, `close_tab`, `select_tab`, `click`, `type`, `press_key`, `hover`, `scroll`, `fill`, `select_option`, `upload`, `resize`, `handle_dialog`, `eval_js`, `cdp` |
-| always allowed | `policy_get`, `policy_tighten` (tightening is safe by construction) |
-
-## Enforcement (extension)
-
-The gate sits in `packages/extension/src/lib/dispatch.ts`, before the method
-switch:
-
-1. Resolve the target tab (reuse `resolveTabId` from `cdp.ts`; tab
-   resolution is centralized here so the gate and the handler agree on the
-   target).
-2. Extract the tab URL's host; compute the effective tier.
-3. Compare against the method's required tier. On failure, throw a
-   `FrameError`-shaped error:
-   `{ code: "policy_denied", message: "blocked by policy: <host> is read-only — grant full access from the reins extension popup" }`.
-   The message always names the host, its current tier, and the remediation.
-
-Special cases:
-
-- **`navigate` / `open_tab`** additionally check the **destination** host —
-  both current and destination hosts need `full`. `back`/`forward`/`reload`
-  have unknowable destinations; current host at `full` suffices.
-- **`deny` tier** refuses every tab-scoped method. `list_tabs` **redacts**
-  denied tabs rather than omitting them: `tabId` kept, `url` and `title`
-  blanked, `blocked: true` added to the Tab shape. No information leak, but
-  the agent is not gaslit when the active tab is denied.
-- **`policy_tighten`** applies only when the new tier is strictly lower than
-  the current tier for that exact pattern. Raising a tier or deleting a rule
-  is rejected with the popup hint. The comparison runs in the extension —
-  the daemon cannot fake it.
-- **Iframes.** Cross-origin iframes are governed by the top-level page host.
-  Frame-granular policy is out of scope for v0.3 (the future threat-model
-  doc will note this).
-
-Caching: the service worker keeps the policy in memory, refreshed via
-`chrome.storage.onChanged`. The cache is initialized before dispatch accepts
-work; if initialization fails, dispatch refuses all requests (fail closed).
-
-## Protocol additions
-
-- `policy_get` → returns the current `Policy`.
-- `policy_tighten` `{ pattern, tier }` → applies iff strictly tightening;
-  otherwise a `policy_denied`-class error with the popup hint.
-- `Tab` gains optional `blocked: boolean` (redacted entries).
-- `FrameError` code `"policy_denied"` (the `code` field already exists).
-
-## Surfaces
-
-### CLI — `reins policy`
-
-- `reins policy` — show `defaultTier`, rules, and the effective tier for
-  each open tab's host (via `policy_get` + `list_tabs`).
-- `reins policy deny <pattern>` / `reins policy readonly <pattern>` —
-  tighten via `policy_tighten`.
-- `reins policy allow <pattern>` — exists but always errors:
-  `grants require the extension popup — click the reins icon in <browser>`.
-  Deliberate: a discoverable path that teaches agent and user where grants
-  live.
-- `--browser <id>` routes like every other command; ambiguity with multiple
-  browsers handled the same way existing commands handle it.
-
-### Popup — "Site permissions" section
-
-Below the connection status:
-
-- **Current-tab row.** Host of the active tab + 3-way segmented control
-  (full / read / deny). This is the one-click grant path.
-- **Rules list.** Each rule: pattern, tier, delete button. Add-rule input
-  for wildcard patterns.
-- **Default stance.** 3-way control for `defaultTier`.
-- The popup writes `chrome.storage.local` directly — it *is* the user
-  gesture; no tighten-only restriction applies.
-
-## Error handling
-
-- `policy_denied` errors flow through the existing error path: CLI prints
-  the message and exits nonzero.
-- SKILL.md gets a short gotcha (not the full hardening pass): commands can
-  fail with `policy_denied` — relay the popup instructions to the user; do
-  not retry.
-
-## Testing
-
-- **protocol**: tier-map completeness (compile-time via `Record<Method,
-  Tier>`); matcher precedence table test (exact > longest wildcard >
-  default; apex matching; scheme/port stripping; pattern validation).
-- **extension**: policy unit tests (matching, tighten-only, redaction);
-  dispatch gate tests — `read` host allows `read_snapshot`, blocks `click`;
-  `deny` blocks everything and redacts `list_tabs`; `navigate`/`open_tab`
-  destination check; fail-closed on cache init failure.
-- **cli**: `reins policy` arg parsing; `allow` error path; output
-  formatting.
-- **integration.test.ts**: the stub extension gains policy state; end-to-end
-  — tighten to `readonly`, `click` fails with `policy_denied`, `snapshot`
-  succeeds.
-- Operational note: rebuild `@reins/protocol` before running cli/extension
-  tests.
-
-## Out of scope (v0.3, this slice)
-
-- Audit log (`reins audit`) — next Phase 1 slice.
-- SECURITY.md threat-model doc — next Phase 1 slice.
-- Full SKILL.md hardening pass (prompt-injection section).
-- Frame-granular policy; per-category deny lists ("deny-sensitive-
-  categories" from the roadmap — revisit once real usage shows demand).
-- Firefox / non-Chromium.

-# Tab groups — design
-
-Date: 2026-09-26
-Status: approved in chat, pending spec review
-
-## Problem
-
-Users want to see which tabs their agent is working in. Chromium tab groups
-are the natural marker, and they're also a general "organize my tabs" tool.
-reins works with any Chromium browser (Chrome, Edge, Brave, Vivaldi, Opera,
-Arc, Dia, …), and not all of them support tab groups.
-
-## Principle
-
-reins ships **primitives only**: list, create/add, edit, ungroup. It never
-groups anything on its own. The agent decides when and how to group (for
-example "put the tabs I opened for this task in a group titled `reins`"),
-the same way it decides what to click.
-
-## Scope
-
-In:
-
-- `Tab.groupId` in `reins tabs`
-- `reins groups`: list groups
-- `reins group`: create a group, add tabs to a group, edit a group's title,
-  color, or collapsed state
-- `reins ungroup`: remove tabs from their group, or dissolve a whole group
-- A clear `unsupported` error on browsers without tab groups
-- Skill and web docs, store/privacy permission text, changeset
-
-Out (YAGNI):
-
-- Auto-grouping, a popup toggle, or any other extension-side behavior
-- Deleting a group together with its tabs. `ungroup` never closes tabs; the
-  agent uses `reins close` when it means to close them.
-- Moving groups between windows, or reordering groups
-- Advertising a per-browser capability in the hello/roster
-
-## CLI (flat verbs, matching tabs/open/close/focus)
-
-```
-reins groups [--browser <id>]
-reins group --tab <id> [--tab <id> …] [--group <gid>] [--title <t>] [--color <c>] [--collapse|--expand]
-reins group --group <gid> [--title <t>] [--color <c>] [--collapse|--expand]
-reins ungroup --tab <id> [--tab <id> …]
-reins ungroup --group <gid>
-```
-
-- `group` with `--tab` maps to `group_tabs`. Without `--group` it creates a
-  new group; with `--group` it adds the tabs to that group. Title, color, and
-  collapsed are applied afterwards. Prints `group <gid>`.
-- `group` with `--group` and no `--tab` maps to `update_group`. It needs at
-  least one of `--title`, `--color`, `--collapse`, or `--expand`.
-- `group` with neither `--tab` nor `--group` is a UsageError.
-- `--collapse` and `--expand` together is a UsageError.
-- `ungroup` needs exactly one of `--tab` (repeatable) or `--group`.
-- `--color` must be one of: grey, blue, red, yellow, green, pink, purple,
-  cyan, orange. Anything else is a UsageError.
-- `tabs` text output gets a group marker per grouped tab (`g<gid>`).
-- `groups` text output: one line per group,
-  `<browserId>  group <gid>  "<title>"  <color>  <n> tabs[  (collapsed)]  window <wid>`.
-  Prints `(no groups)` when there are none.
-- Help lists `groups`, `group`, and `ungroup` under "Tabs & pages".
-
-## Protocol (`@reins/protocol`)
-
-- `Tab` gets `groupId: z.number().optional()`. It's left out when the tab is
-  ungrouped (Chrome reports `-1`) or when the browser has no groups.
-- `TabGroupColor = z.enum([grey, blue, red, yellow, green, pink, purple, cyan, orange])`
-- `TabGroup = { groupId, title, color, collapsed, windowId, tabCount, browserId?, browser? }`
-- `ListGroupsResult = { groups: TabGroup[] }`
-- `GroupTabsParams = { tabIds: number[] (min 1), groupId?, title?, color?, collapsed? }`, result `{ groupId }`
-- `UpdateGroupParams = { groupId, title?, color?, collapsed? }`, result `OkResult`
-- `UngroupTabsParams = { tabIds?: number[] (min 1) , groupId? }`, with exactly one of the two set. Result is `OkResult`.
-- `METHOD_TIERS`: `list_groups`, `group_tabs`, `update_group`, and
-  `ungroup_tabs` are all `"read"`. Grouping never touches page content, so
-  readonly sites can be grouped; denied sites are refused.
-
-## Extension
-
-New module `packages/extension/src/lib/tab-groups.ts`:
-
-- `groupsSupported()`: true only when `chrome.tabGroups?.query`,
-  `chrome.tabGroups?.update`, `chrome.tabs.group`, and `chrome.tabs.ungroup`
-  are all functions.
-- Every handler first calls `requireGroups()`. When groups are unsupported it
-  throws an `Error` whose `code` is `"unsupported"`, with the message: `this
-  browser doesn't support tab groups (chrome.tabGroups unavailable)`. The
-  bridge client already forwards `err.code` in the response frame.
-- `listGroups()`: `chrome.tabGroups.query({})`, with `tabCount` taken from
-  `chrome.tabs.query({})` counted per `groupId`.
-- `groupTabs(p)`: `chrome.tabs.group({ tabIds, groupId? })`, then
-  `chrome.tabGroups.update` if any props were given. Returns `{ groupId }`.
-- `updateGroup(p)`: `chrome.tabGroups.update(groupId, props)`.
-- `ungroupTabs(p)`: when given a `groupId`, it resolves the group's tabs with
-  `chrome.tabs.query({ groupId })`, then calls `chrome.tabs.ungroup(tabIds)`.
-- Chrome's own errors (bad group id, a tab in a non-normal window) pass
-  through unchanged.
-
-`tab-handler.ts` `listTabs()` sets `groupId` when `t.groupId` is a number
-other than `-1`.
-
-`dispatch.ts` gate:
-
-- `list_groups` and `update_group` get no host check. Group titles are the
-  user's own labels, not site content. `list_tabs` redaction already rebuilds
-  blocked tabs from scratch as `{tabId, title:"", url:"", active, blocked}`,
-  so `groupId` is dropped for them. That's consistent: blocked tabs show
-  nothing beyond their id.
-- `group_tabs` and `ungroup_tabs` get a multi-tab check. The gate resolves
-  every target tab (for `ungroup --group`, the group's current tabs), then
-  runs `ensureAllowed(method, host)` on each one. The first denial refuses
-  the whole call, and `PolicyDenied.meta` gets that tab's id. The response's
-  `meta` has no single host or tabId, so it stays `{}`. The audit record
-  still carries the params (the tabIds).
-- The handler receives the resolved `tabIds`, so the gate and the handler
-  act on the same set.
-
-Manifest: add `"tabGroups"` to `permissions`, and update the comment block.
-The permission shows no install warning, so existing users don't have to
-re-approve anything on update. Browsers that don't know the permission
-ignore it with a load-time warning; the extension still loads.
-
-## Daemon (`packages/cli/src/rpc.ts`)
-
-`list_groups` aggregates across browsers the same way `list_tabs` does: it
-fans out to every targeted browser and tags each group with `browserId` and
-`browser`. A browser that fails (`unsupported`, or an older extension that
-answers `unknown method`) contributes no groups and is listed in `skipped`
-(`{browserId, browser, reason, message}`); the text output prints one line
-per skipped browser. If every targeted browser fails, the first error is
-rethrown, rewritten to name the browser. Routed group calls rewrite the same
-way. The call is still audited like any other.
-
-All other group methods route to one browser through the existing
-`bridge.requestFull` path.
-
-## Errors
-
-| Case | Result |
-|---|---|
-| Browser lacks tab groups | `unsupported`: "this browser doesn't support tab groups …" |
-| Older extension without these methods | `unknown method: <m>`, as today |
-| Denied host on any target tab | `policy_denied`, audited with `denied: true` |
-| Bad group id or tab id | Chrome's error message, unchanged |
-| Bad flags | UsageError with usage text |
-
-## Docs
-
-- `skills/reins/SKILL.md`: document the three commands, plus one line of
-  guidance: "you can group the tabs you open for a task (e.g. title `reins`)
-  so the user sees which tabs are yours; don't regroup the user's tabs
-  unless asked."
-- Web docs (`packages/web/src/routes/docs/commands.tsx`): add the three
-  commands.
-- `docs/CHROME_WEB_STORE.md`: add a `tabGroups` justification and update the
-  permission list. `docs/PRIVACY.md`: add a mention if it lists permissions.
-- One changeset per PR (minor bump for cli, extension, and protocol).
-
-## Testing
-
-- protocol: schema tests for the new params (exactly-one rule in
-  `UngroupTabsParams`, color enum) and for `Tab.groupId`
-- extension `tab-groups.test.ts` with stubbed `chrome`: unsupported
-  detection, create, add to existing, props applied, ungroup by tabs,
-  ungroup by group, tabCount
-- extension `tab-handler.test.ts`: groupId is mapped, and `-1` is left out
-- extension `dispatch.test.ts`: multi-tab gate refuses when any tab is
-  denied, lets readonly tabs through, and `ungroup --group` checks the
-  group's tabs
-- cli `commands` tests: build and format for groups/group/ungroup, plus
-  every usage error
-- cli `rpc` test: `list_groups` aggregation, including partial failure and
-  total failure
-- Manual e2e in real Chrome: only on tabs reins opens itself. The user's
-  existing tabs and groups are never touched. Clean up afterwards by closing
-  those tabs.
-
-## Delivery (stacked PRs)
-
-1. `feat/tab-groups`, the read side: protocol `Tab.groupId`, `TabGroup`,
-   and `list_groups`; the `tabGroups` permission; `listGroups` +
-   `groupsSupported`; `reins groups`; the `tabs` marker; daemon
-   aggregation; store/privacy text; skill and web docs for `groups`;
-   changeset.
-2. `feat/tab-groups-write`, stacked on 1: `group_tabs`, `update_group`,
-   `ungroup_tabs`, the multi-tab gate, `reins group`/`ungroup`, skill and
-   web docs for them plus the grouping guidance line, changeset.

-# reins do — design
-
-Date: 2026-09-27
-Status: approved in chat (sections 1–4 + review fixes), pending spec review
-
-## Problem
-
-An agent driving reins pays one full LLM turn per browser action:
-`reins snapshot` → think → `reins click` → think → … A 15-step form takes
-minutes. [browser-use/jev-ultrafast](https://github.com/browser-use/jev-ultrafast)
-(MIT) shows the alternative: TypeSafe's **Jev**, a "System One" model that
-answers typed multiple-choice questions in ~180 ms, picks the next operation
-and its target in one request. Their Google Flights run takes 7.1 s end to end.
-
-## Principle
-
-The calling agent stays in charge. It delegates one bounded, verifiable
-sub-task to `reins do`, supplies every text value itself (`--fill`), and
-verifies the result. Jev only *chooses* among elements that were actually
-observed. Model output never becomes a selector, coordinate, or code. There is
-no text-generating model in the loop, so the only key is the user's TypeSafe key.
-
-## Scope
-
-In:
-
-- `~/.reins/credentials.json` holding the TypeSafe key, shared by all browsers
-- `reins key set|status|clear typesafe`
-- Popup "Jev" section: pitch, save/replace/remove key, status
-- Extension→daemon `call` frame (key methods only)
-- Extension methods `jev_observe` and `jev_act`
-- Daemon Jev loop, `reins do`, `--continue`, `--confirm`
-- Skill, web docs, PRIVACY/SECURITY/CWS disclosure, changeset
-- Offline tests, extension browser tests, a manual paid benchmark
-
-Out (YAGNI for v1):
-
-- A text LLM / OpenRouter key (agent supplies text)
-- A `low_confidence` stop (Jev target probabilities over 30+ elements are
-  routinely < 0.5; measure before adding)
-- Per-site Jev opt-out or a built-in denylist (the user owns the key and the
-  decision; we disclose clearly instead)
-- Masking filled values in later snapshots
-- `TYPESAFE_API_KEY` env var
-- Streaming step progress to the CLI
-- iframes, shadow DOM, uploads, pop-up tabs, canvas (inherited jev limits)
-- Background-tab execution without activation (tracked by #37's
-  focus-emulation spike)
-
-## Key storage and setup
-
-**File.** `~/.reins/credentials.json`, mode `0600`, written atomically
-(temp file in same dir → `rename`). Shape: `{ "typesafe": "<key>" }`. Only
-the daemon reads it. Read fresh at the start of every `do` run, held in memory
-only for that run.
-
-**CLI.**
-
-```
-reins key set typesafe      # hidden prompt; or: echo "$K" | reins key set typesafe
-reins key status            # typesafe: set (••••a1b2) | not set
-reins key clear typesafe
-```
-
-`set` validates the key with one minimal `systemone` call (a one-question
-noul on a tiny state) before writing; a 401 prints `TypeSafe rejected this
-key` and writes nothing. These are daemon RPCs (`key_set`, `key_status`,
-`key_clear`) so the CLI and popup share one code path.
-
-**Popup "Jev" section** (under the connection block):
-
-- *No key:* one line of pitch: "Add a Jev key and `reins do` runs whole
-  browser tasks in seconds, not minutes." Link to
-  `https://console.typesafe.ai/keys` and to the docs' "what is sent" section.
-  Masked input + **Save**.
-- *Key set:* `Jev ready · ••••a1b2` + **Replace** / **Remove**.
-- *Daemon not connected:* input disabled, "Start reins to save a key".
-- Save shows the daemon's validation error inline.
-
-**`call` frame (extension → daemon).** New in `@reins/protocol`:
-
-```ts
-CallFrame = { type: "call", id: string, method: string, params: unknown }
-```
-
-The daemon answers with the existing `ResponseFrame` (same `id`). The
-extension's `BridgeClient` gains a small pending-call map mirroring the
-daemon's. The daemon accepts `call` only from an already-welcomed browser and
-only for `key_set`, `key_status`, `key_clear`. Anything else →
-`{ ok: false, error: { code: "METHOD_NOT_ALLOWED" } }`. Popup → background →
-offscreen → WS, reusing the existing `chrome.runtime` message path.
-
-**Invariants.** The key is never returned by any method (status returns only
-`set` + last 4), never sent to a page or the extension beyond the single
-save hop, and never written to the audit log (`key_set` is logged with its
-params dropped).
-
-## CLI
-
-```
-reins do "<goal>" [--fill name=value]... [--confirm "<label>"]... [--continue]
-                  [--tab <id>] [--browser <id>] [--max-steps 30] [--timeout 60] [--json]
-```
-
-- Acts on the active tab by default, like every page command. Never navigates
-  on its own; the agent runs `reins open` first.
-- `--fill` repeatable; `name` is `[a-z0-9_-]+`, `value` is any string.
-- `--confirm` repeatable; pre-approves a click on an element whose normalized
-  label equals the given string, once per flag.
-- `--continue` resumes this tab's last run (see Runs). `<goal>` is optional
-  with `--continue`; new `--fill`/`--confirm` merge into the run.
-- `--max-steps` counts executed actions (default 30). Jev calls are capped at
-  `2 × max-steps` to bound stale re-observations.
-- `--timeout` is wall-clock seconds for the whole run (default 60). The CLI's
-  HTTP wait for `do` is `timeout + 10 s` (today it is a fixed 30 s,
-  `cli.ts:24`; `rpc()` gains a `timeoutMs` option).
-
-### Result
-
-Exit code: `0` done, `2` handoff, `1` error.
-
-| status | when | printed `next:` |
-|---|---|---|
-| `done` | Jev chose DONE on a fresh page | `reins snapshot` (verify; DONE is not proof) |

-
-| file | job |
-|---|---|
-| `credentials.ts` | read/write/clear `credentials.json` (0600, atomic) |
-| `client.ts` | thin wrapper over the official SDK `@typesafe-ai/sdk` (MIT, zero deps, Node ≥ 20; pinned exact): `TypeSafeClient.systemOne` with the run's `AbortSignal`, the SDK's default retries (408/429/5xx, 2 retries, honours Retry-After), 8 s per attempt, logging off. On top of the SDK's typing, validate every choice answer (choice ∈ offered, probabilities keyed exactly by the options, each in [0,1], sum within 0.02 of 1). Invalid → throw, nothing executes. `AuthenticationError`/`PermissionDeniedError` → "TypeSafe rejected the API key". |
-| `space.ts` | snapshot → indexed element list + questions (port of jev `model.py` `action_space`/`choose`) |
-| `prompts.ts` | port of jev `questions.py` + fill rules |
-| `loop.ts` | the run state machine |
-| `runs.ts` | per-tab run memory, mutex, loop breaker |
-
-`rpc.ts` handles `do` in the daemon (it is not forwarded as one bridge call);
-the loop issues `jev_observe` / `jev_act` through the existing
-`bridge.requestFull()` with the normal 30 s per-call timeout.
-
-### One step
-
-1. **Check abort.** The loop receives an `AbortSignal` wired to the HTTP
-   request's `close` event (`daemon.ts` `/rpc` handler) and to `--timeout`.
-   Checked before every Jev call and every `jev_act`. Ctrl-C or a dead agent
-   stops the run before the next action.
-2. **Observe** (`jev_observe`). If `dialog` is set → stop `dialog`. If the page
-   is hidden → stop `interrupted` (except on the first step, where `jev_act`'s
-   `ensureVisible` brings the tab forward as `click` does today).
-3. **Ask Jev** (one request, speculative fan-out):
-   - `operation`: CLICK / TYPE_TEXT / SELECT (only those with candidates),
-     SCROLL_UP / SCROLL_DOWN / WAIT, DONE, BLOCKED
-   - `click_target`, `type_text_target`, `select_target`: one per offered
-     operation, each listing only compatible elements
-   - **fill heads, one per text field:** when fills exist, `fill_for_<i>` for
-     each TYPE_TEXT candidate `i` (the first 8 in document order). Options are
-     `name: value` for every fill plus `NONE`. Instructions: "If the next
-     action types into field [i], which value belongs in it?" Each head is
-     conditioned on its own field, so from/to with two city values are
-     answered per field, still in one round trip. If Jev picks a TYPE_TEXT
-     target outside the first 8, one extra request asks that field's head
-     alone.
-4. **Gate** (stop rules below). Only the chosen operation's target is used.
-5. **Act** (`jev_act`). A `stale` result means the target changed or is
-   covered: re-observe without counting a step (counts toward the Jev-call
-   cap).
-6. **Record** the step before observing the result; `pageChanged` is filled
-   in by the next observation.
-
-State sent to Jev per request: goal; url, title; visible viewport text
-(capped at 6,000 chars); elements (index, role, label, value,
-checked/selected/expanded, options for native selects); last 10 actions
-(`op`, label, fill name, pageChanged); fill names and values. Never sent:
-password, file, or hidden inputs (the snapshot skips them) and the key.
-
-### Stop rules
-
-- **Risky click.** Case-insensitive **whole-word** match of the target's
-  label against: `buy, pay, purchase, order, checkout, send, post, publish,
-  share, invite, delete, remove, transfer, unsubscribe, approve, authorize,
-  accept`. Also risky: a click target with **no accessible name** (label is
-  empty or equals its role). Not risky: labels matching a `--confirm` value,
-  or whose normalized full label appears verbatim in the goal (goal "book the
-  9:40 flight", label "Book" → allowed; goal "delete the spam", label "Delete
-  account" → stops). Generic `submit / confirm / continue / next / search` are
-  not on the list; stopping every search form would cause the back-and-forth
-  this command exists to remove. The skill states that this is a heuristic
-  with holes (other languages, odd labels), not a guarantee.
-- **left_site.** Before each act, the current host must equal the run's start
-  host or be a subdomain of it, or vice versa (`a === b || a.endsWith("." + b)
-  || b.endsWith("." + a)`). No public-suffix list. Login redirects to another
-  host stop the run, which is fine.
-- **stuck.** 3 consecutive non-WAIT actions whose next observation has the
-  same fingerprint. The fingerprint is `url + text + elements` and **excludes
-  scroll position**, because `actionPoint` scrolls targets into view
-  (`actionability.ts:92`).
-- **budget.** `step == maxSteps`, `jevCalls == 2 × maxSteps`, or timeout.
-
-### Runs (`runs.ts`)
-
-- Keyed by `browserId:tabId` (tab ids repeat across browsers).
-- One run per tab at a time: a second `do` on a busy tab fails fast with
-  `a reins do run is already active on this tab`.
-- Kept in daemon memory after the run stops: goal, start host, fills,
-  confirms, history, step count, last fingerprint. Evicted after 15 minutes or
-  when a new non-continue run starts on the tab.
-- `--continue` with nothing stored →
-  `no run to continue on this tab (runs are forgotten after 15 minutes or a daemon restart) — run reins do "<goal>" again`.
-- **Loop breaker.** A `--continue` run that ends without any page change stops
-  `stuck`, and marks the run. The next `--continue` on that tab is refused
-  until the page's fingerprint differs from the stored one.
-- `--continue` keeps the run's history and step count (numbering carries on:
-  `12/30` → `12/42`). Each invocation gets its own budget of `--max-steps` more
-  actions, its own Jev-call cap, and its own `--timeout`, so a run that stopped
-  on `budget` can actually continue.
-
-### Daemon restarts and version skew (#39)
-
-`reins restart`, `reins kill`, and `ensureDaemon`'s automatic restart of a
-daemon older than the CLI all go through `POST /shutdown`.
-
-- **Shutdown during a run.** `/shutdown` aborts every active run through the
-  same `AbortSignal` (no new action starts), waits up to 1 s for an in-flight
-  `jev_act` to return, and answers each waiting `do` with status
-  `interrupted`, reason `daemon restarting`, the steps so far, and
-  `next: reins do --continue`. That `--continue` then reports
-  `no run to continue on this tab (runs are forgotten after 15 minutes or a daemon restart) — run reins do "<goal>" again`,
-  because run memory is in-process. The key file is on disk, so restarts never
-  lose it.
-- **Older daemon, newer CLI.** Handled already: `ensureDaemon` restarts it
-  before `do` is sent.
-- **Older extension, newer daemon.** `jev_observe` comes back unknown. `do`
-  fails with `the reins extension is too old for reins do — update it (reins
-  extension --reload for unpacked builds)`.
-- **Newer extension, older daemon.** The old daemon ignores `call` frames. The
-  popup times out a `call` after 5 s and shows `update the reins CLI and run
-  reins restart`.
-- The popup re-fetches `key_status` whenever it opens or the connection comes
-  back, so a restart never leaves a stale "Jev ready".
-
-## Extension
-
-Two new bridge methods, both `full` in `METHOD_TIERS`, gated per call by
-`gate()` (so a mid-run navigation to a stricter host is refused there).
-`observe` needs `full` because page content leaves the machine; `do` acts
-anyway.
-
-**`jev_observe { tabId? } → JevObservation`**
-
-- One `Runtime.evaluate` of `lib/jev-snapshot.ts`: a port of jev's
-  `snapshot.js` (common HTML + ARIA controls, `checkVisibility`,
-  viewport-only, skips password/file/hidden, native select options,
-  recursive label names). Node identity lives in an in-page cache under
-  `Symbol.for("reins.jev")`, the same pattern as the existing pointer probe.
-  It is separate from `reins snapshot`'s `data-reins-ref` (issue #37 may unify).
-- Returns `{ url, title, text, visible, elements, fingerprint, pageKey,
-  guards, dialog? }`. Nothing tracks dialogs today. Add a per-tab dialog
-  flag fed by `chrome.debugger.onEvent` (`Page.javascriptDialogOpening` sets
-  it, `…Closed` clears it). Page events are already on for sessions armed by
-  the autofill guard, which `jev_act` uses (`withDebugger(…, { guard: true })`).
-  `jev_observe` checks the flag **before** evaluating, because an open dialog
-  blocks `Runtime.evaluate` (`cdp.ts:163`). A dialog opened by an action
-  surfaces on the next observe.
-
-**`jev_act { tabId?, node, op, value?, delta? } → { ok: true } | { stale: true, reason }`**
-
-- Resolve `node` from the cache. Missing, disconnected, or guard mismatch →
-  `stale`.
-- **click**: reuse the #30 click path (`ensureVisible` → `actionablePoint` →
-  pointer events → landed check), refactored so it can take a resolved
-  element instead of re-querying a CSS selector each attempt. `jev_act` passes
-  an actionability timeout of **500 ms** (today's `ACTION_TIMEOUT_MS` is 5 s)
-  and maps "covered" or "still moving" to `stale`. The loop re-observes, and
-  the covering modal is then in the element list.
-- **type**: click to focus (same path), select-all
-  (`Input.dispatchKeyEvent` with the `selectAll` command, Meta on macOS,
-  Ctrl elsewhere), then `Input.insertText`.
-- **select**: native `<select>` only. Set `value`, dispatch `input` and
-  `change`. If the option vanished, return an error (not `stale`), so the loop
-  never retries an uncertain mutation.
-- **scroll**: `mouseWheel` at viewport centre, `deltaY ±600`.
-- **wait**: 250 ms.
-- **Settle**, after any input: at most 2 animation frames or 50 ms; for a
-  typed combobox, up to 200 ms or until a visible `[role=option]` appears
-  (port of jev `observe`'s after-input wait).
-
-## Audit
-
-- One `do` entry per run: goal, status, steps, jevCalls, elapsedMs; `fills`
-  values redacted (add `fills` to `redactParams` with a test row, keep names).
-- One `jev_act` entry per action through the normal bridge audit hook: host,
-  op, label; `value` already redacted by `VALUE_KEYS`.
-- `key_set`: logged without params.
-
-## Docs
-
-- `docs/PRIVACY.md`: new section "Optional: reins do with Jev". It says that
-  when you add a TypeSafe key and run `reins do`, the **daemon** sends the
-  state listed above to `api.typesafe.ai` under your TypeSafe account, that
-  nothing is sent without a key, and that the extension itself still makes no
-  remote requests. Update "What reins does NOT do" to scope the "no remote
-  server" line accordingly.
-- `docs/SECURITY.md`: threat notes: page text can try to steer Jev (it can
-  only choose observed elements; risky-label stop is a heuristic); the key
-  file's location and permissions.
-- `docs/CHROME_WEB_STORE.md`: data-disclosure update (popup accepts an API
-  key and passes it only to the local daemon).
-- Web docs: `reins do` and `reins key` command reference, a "what is sent"
-  section, and a changelog entry.
-- `skills/reins/SKILL.md`: when to use `do` (multi-step forms, search and
-  filter flows, navigation), and to pass every value from the goal as `--fill`
-  up front. Pre-confirm the final action when the user asked for it. Follow
-  the printed `next:` line. Always verify after `done`. Switch to manual
-  commands on `stuck`.
-- Changeset (minor).
-
-## Testing
-
-Offline (CI, no paid calls):
-
-- `space.ts`: fixture snapshots → questions; each operation offers only
-  compatible elements; fill heads only for TYPE_TEXT candidates, capped at 8.
-- `client.ts`: invalid answers throw (choice not offered, bad probability
-  keys or sum, missing head); retry/backoff on 429/503/529; 401 surfaces as a
-  key error.
-- `loop.ts` with a fake Jev + fake bridge: every status fires; abort before
-  act on request close; stale → re-observe without a step; `--continue` keeps
-  history and budget; `--confirm` allows exactly one click; goal-verbatim
-  pre-approval; whole-word risky matching ("Remove filter" stops, "Postcode"
-  does not); scroll-only changes do not count as progress; loop breaker.
-- `runs.ts`: `browserId:tabId` keying, busy-tab refusal, eviction, restart
-  message.
-- `credentials.ts`: 0600, atomic replace, clear.
-- Protocol: `CallFrame` schema; the daemon rejects non-key `call` methods;
-  `redactParams` row for `fills`.
-
-Extension browser tests (style of `pointer.browser.test.ts`), local fixtures:
-
-- A fixed-position modal is listed; disabled, hidden, and covered elements
-  are excluded; password never listed; select options listed.
-- A replaced node between observe and act → `stale`; covered target →
-  `stale` within ~500 ms.
-- Typing replaces existing text; native select fires `change`; combobox
-  settle waits for options.
-
-Popup: the three key states render; save error shown inline.
-
-Manual paid benchmark (`packages/cli/scripts/bench-do.ts`, never in CI):
-
-- Tasks: Google Flights one-way search (two fills), open a named Wikipedia
-  article, a GitHub search with a filter, and one site with a cookie banner.
-- Two arms: `reins do` vs `claude -p` driving reins step by step with the same
-  goal. At least 5 runs per task per arm.
-- An independent checker verifies each outcome (URL, fields, results). Speed
-  is compared only on verified runs.
-- Ship bar: verified success of `reins do` ≥ manual on every task, and median
-  wall time on verified runs ≥ 3× faster.
-

+//              rewrites it to http://127.0.0.1:<port>/<file>
+//   goal       what `reins do` is told
+//   fills      --fill values (the manual arm gets them in its prompt)
+//   check      JS expression evaluated in the final tab (with `await` support);
+//              true only in the goal state
+//   checkNote  plain words: what the check proves
+//   expect     optional { status } — the correct outcome is a stop, not `done`
+//   timeoutSec optional `reins do --timeout` (default 60)
+//
+// Dev/holdout split (decided before any run, never re-balanced afterwards):
+// walking each tier's list in the order written below, every third task was
+// holdout so both tiers sat in both sets and holdout was ~30% of the whole.
+// Fixture: datepicker, newtab (2 of 7). Live: mdn, cambridge, hackernews,
+// pypi, wolframalpha (5 of 15). Holdout = 7 of 22 (32%).
+//
+// holdout v1 folded into dev on 2026-09-27 after its first run: those 7 tasks
+// have been seen (and their failures discussed), so they no longer measure
+// generalisation. They are `set: "dev"` now.
+//
+// holdout2 (8 tasks, the "former holdout2" section below) was frozen on 2026-09-27 before
+// round 3 of fixing began, its checkers validated WITHOUT `reins do` (evidence:
+// .superpowers/sdd/2026-09-27-reins-do/holdout2-report.md). holdout2 folded
+// into dev after its first run on 3c8a364 (16/40): those tasks have been seen
+// and their failures discussed, so they are `set: "dev"` now.
+//
+// holdout3 (8 tasks, the last section below) was frozen on 2026-09-28 before
+// any `reins do` run on it, built while HEAD was f1af855. Its checkers were
+// validated WITHOUT `reins do` (evidence:
+// .superpowers/sdd/2026-09-27-reins-do/holdout3-report.md). Never look at it
+// while fixing reins; fold it into dev after its first run, as with the others.
+//
+// The fixture pages are excluded from biome on purpose: they copy real sites'
+// markup (ul[role=listbox] > li[role=option], li[role=menuitemradio] menus,
+// table[role=grid]) so the extension sees what it sees in the wild, and
+// biome's a11y rules object to exactly those patterns.
+//
+// Checker validation (false on the start page, true on a goal state reached
+// without `reins do`) is recorded in
+// .superpowers/sdd/2026-09-27-reins-do/bench-v2-report.md.

+
+**Use it for** searches, filters and sorting, multi-step forms, consent
+banners, date pickers and plain navigation ("open the X page"). **Don't use it
+for** logins, anything that needs a password, reading or extracting data
+(`reins text` / `reins eval` are exact and cheaper), or steps you'd want to
+watch one by one.
+
+### Calling it
+
+- **Every value the goal mentions goes in `--fill name=value`**: search terms,
+  names, amounts, codes a picker needs (`--fill to=JPY`). Jev chooses which
+  field gets which value; it never invents text. A field with no matching fill
+  stops the run with `needs_text`. Fills are sent to TypeSafe with the page, so
+  never pass a password (password fields are never read anyway).
+- **Say the whole goal, including the end state**: "sorted by most stars",
+  "stop when results show". Jev stops as soon as it thinks the goal is met.
+- **Pre-approve the final action only if the user asked for it**:
+  `--confirm 'Book'`, or name the button as a whole word in the goal ("… and
+  pay now"). Otherwise clicks on buy/pay/send/delete-style buttons stop the
+  run. "Accept" on a cookie or consent banner never needs approval.
+- Single-quote goals and labels (the `next:` lines do too): page labels can
+  contain `$` or backticks.
+- Takes `--tab`, `--browser`, `--json`, `--max-steps` (30) and `--timeout`
+  (60 s) like other page commands.
+
+### Reading the result
+
+| Outcome | What it means | What you do |
+|---|---|---|
+| `done … self-check 0.9` (exit 0) | Jev says the goal is met and its own check agrees | Glance at the page (`reins snapshot` / `reins text`) before you report success |
+| `done (unsure: self-check 0.3)` (exit 0) | Jev stopped, but its check says the goal is probably **not** met | **Verify, then finish the missing part step by step.** Don't report success |
+| `risky_action` (exit 2) | The next click looks irreversible (pay, send, delete, …) | Ask the user; if they agree, run the printed `next:` line (it adds `--confirm`) |
+| `needs_text` (exit 2) | A field needs a value you didn't pass | Re-run the `next:` line with the missing `--fill` |
+| `dialog` (exit 2) | A JS alert/confirm is open | `reins dialog --accept` or `--dismiss`, then `reins do --continue` |
+| `left_site` (exit 2) | The page moved to another site | Decide whether that's expected; continue manually if so |
+| `stuck` / `blocked` (exit 2) | Jev can't make progress here | Switch to step-by-step for this part; the page is left where it stopped |
+| `budget` / `interrupted` (exit 2) | Out of steps/time, or the tab was hidden/closed | `reins do --continue` (fresh budget), or finish manually |
+| error (exit 1) | reins or TypeSafe failed; nothing more was done | Read the message; retry once or go manual |
+
+The self-check is the number to trust. On reins' benchmark every wrong `done`
+was marked unsure; about one right `done` in seven is marked unsure too, so
+unsure means "check", not "failed".
+
+`--continue` resumes the same run on the same tab. Runs are forgotten after 15
+minutes or a daemon restart; if `--continue` says so, start over with the goal.
+
+### Limits
+
+- Jev sometimes declares `done` before every constraint is applied (a filter
+  or sort left unset, a date picked but not confirmed). That's what the
+  self-check catches; verify the constraint you care about.
+- On pages with two similar search boxes (site-wide vs. this list) it can pick
+  the wrong one.
+- It reads open shadow DOM, not closed shadow roots, and only what the page
+  exposes: a site that labels its fields wrongly confuses it.
+- The risky-click stop is an English-word heuristic plus "unlabelled buttons
+  stop". Don't rely on it for anything you wouldn't do yourself.
+
+No key (`reins do` says so)? Ask the user to run `reins key set typesafe`
+themselves or save it in the reins extension popup. Never ask them to paste a
+key into the chat.
