Add an opt-in byte ceiling for usage.jsonl. When configured in config.json as usageLedgerMaxBytes (minimum 1 MiB), the ledger is truncated after each append by keeping only the newest complete JSONL rows that fit within the budget. Truncation uses atomic file replacement and invalidates both the in-memory usage cache and the derived routing-history.sqlite index. Key safety properties: - Default: no limit (existing behaviour preserved exactly) - Only complete JSONL rows retained; partial/torn tails discarded - Single oversized row kept rather than producing empty file - Best-effort: failures never block the request path - Per-process flag prevents concurrent/re-entrant truncation - No scheduler, worker, or background lifecycle needed Closes the intent of lidge-jun#4042 with 8 files / ~540 lines vs 48 files.
- Mount UsageLedgerRetentionControl in Usage dashboard page with toggle and MiB stepper - Add GET/PUT /api/storage/usage-ledger-retention management endpoints to read and persist policy - Localize all 10 supported UI languages (en, zh, zh-TW, ja, ko, de, fr, ru, tr, vi) - Add comprehensive GUI test suite in gui/tests/usage-retention-control.test.ts - Include verified runtime UI screenshots in .github/pr-assets for PR quality gate
…nd validation - Use bounded 64 KiB chunk scanning and copy in ledger retention rather than full-size buffer allocation - Roll back live memory config when management PUT persistence fails - Discard unterminated/corrupt oversized crash tails while preserving valid oversized lines - Add usage.retention.loadError localization across 10 languages and use on GET error - Fix Storage component exclusion assertion in test
…lid oversized rows - Ensure fsyncSync on temp file descriptor before close, and sync parent dir on POSIX - Retry partial writeSync calls in retention chunk copy loop and assert non-zero write progress - Isolate valid newest oversized rows while discarding older content and invalid tails - Fix French usage.retention.disabled translation to describe automatic deletion rather than compression
- Support arbitrary row lengths in isRangeValidUsageRow up to 2 GiB safe memory threshold - Add unit test verifying a valid oversized usage entry > 10 MiB is preserved
…d corrupt data - Distinguish 'unverifiable' (I/O error, read failure, >64MB) from confirmed 'invalid' - Preserve original file if oversized row cannot be definitively verified rather than discarding - Validate opening character without allocating full buffer
- Validate [foundLastLf, fileSize) range before deciding whether to keep or discard tail - Add regression coverage for older complete rows followed by valid unterminated record
…s and scope - Use readAllSync for bounded reading and retry short writes - Close SQLite request history index before unlinking derived database files - Add low-watermark hysteresis (90% target) to avoid rewrite churn after every append - Restrict UsageLedgerRetentionControl to standalone mode, omitting in connected hub views - Wire localized usage.retention.invalid error message with aria-describedby - Update usage.retention.disabled in all languages to describe automatic deletion rather than compression
…ate Turkish locale - Append newline to preserved unterminated valid tail so subsequent appends do not merge into single invalid line - Update Turkish usage.retention.disabled message to use temizleme (cleanup) instead of sikistirmasi (compression)
…egration tests - Verify ctx.principal is gui-session or admin-token before handling storage retention routes - Add end-to-end integration tests for appendUsageEntry with retention on normal and ENOENT recovery paths
- Exercise GET and PUT /api/storage/usage-ledger-retention using gui-session principal directly against route handler to reflect GUI-only contract
- Match route scanner convention with explicit method guards on GET and PUT - Keep GUI-session principal requirement on both endpoints - Pass management-route-registry reconciliation and method-scan tests

Disposition from the retry and event-model consolidation that landed on This pull request is not superseded and is not being closed. Recording why it did not land in that branch, so the next step is explicit: Sound retention work on the canonical ledger, and orthogonal to the stage and event model. It also changes GUI surface, which a branch that may not build or run the GUI cannot evidence. |

Each item that did not land carries the reason that is true against current dev, not the one written a day ago. #3748's blocker is now narrower and more useful than "parallel store": the recorder does not yet record why a request finally failed, so there is nothing closed to group by. #3983's emission path turns out not to be ephemeral, because stderr is redirected to the service log under both launchd and systemd. #5063 has a concurrent-append data-loss window that the rename cannot see. Retention and masking are stated in one table rather than reimplemented, with the policy that projections inherit both instead of getting their own.

* refactor(usage): one terminal classification for a finished request Three surfaces answered "how did this request end" three different ways. The durable row carries terminalStatus and closeReason, the Prometheus exporter had its own private classifyResult, and the dashboard read the numeric HTTP status and nothing else. That is not cosmetic. A turn cut short by max_output_tokens is durably status 200 with terminalStatus "incomplete", which the exporter reports as incomplete and the dashboard rendered as a green 200: the metric and the operator disagreed about whether the user got an answer. Move the classifier into src/usage/request-outcome.ts and have the exporter import it, including its result label set, so the four strings are stated once. Semantic terminal facts are read before the numeric status, which is the whole point; the status is consulted only when no terminal event was recorded. The module also names the send totals a surface should show, because reporting sends without the unresolved remainder is how a duplicate-send incident stays invisible. It is a leaf: its only import is a type. * fix(gui): make the logs page agree with the ledger and the exporter Carries the rehydration half of #2366 — the half that brings the durable terminal facts out to where an operator reads them. Its separate attribution vocabulary is deliberately left behind, because the landed stage and cause model already owns that question and two vocabularies for one thing is the class of defect this batch exists to remove. The page classified every request by its numeric HTTP status alone and showed no send count at all, so it disagreed with both other surfaces about the same request. A turn cut short by max_output_tokens is durably incomplete and is reported incomplete by the exporter; the page rendered a green 200. The data was never missing — /api/logs spreads the whole durable entry — the page simply did not declare terminalStatus, closeReason or spend. It now declares them and calls the shared classifier rather than reimplementing the precedence, so agreement is structural instead of a rule someone maintains. It also shows the upstream send count, and names the unresolved remainder when there is one, because a send total without it is how a duplicate-send incident stays invisible. The recovery-kind union is now the durable roster instead of a copy. The copy had drifted to nine of thirteen members, so key-401, oauth-account-429, opaque-blob-rejection and reasoning-effort-downgrade each reached the operator as "Unknown recovery reason" — four real causes rendered as an absence of one. The satisfies clause makes the next added kind a typecheck failure here rather than a silent fallback, and the four missing labels are added across all ten catalogs. Co-authored-by: chilung <b0423031@gmail.com> * test(usage): hold the three surfaces to one answer The exporter is driven over the full cross product of status, terminal status and close reason and its emitted result label is compared against the shared classifier, so the two cannot drift apart without a case objecting. The cases that actually broke are asserted by name as well: an incomplete 200 is not a success, and a cancelled 200 is aborted. A source oracle holds the dashboard to the same contract. It has to call the shared classifier rather than read the status, it has to show the send total and the unresolved remainder, and its recovery-label map has to cover every member of the durable roster. That last one is a source oracle rather than a type check because the page is compiled by a separate project, which is how the copy drifted to nine of thirteen members unnoticed in the first place. Every label key the page names is required to exist in all ten catalogs, so a new recovery kind cannot ship with an English label and nine blanks. One case asserts the exporter's whole label set is still protocol, result, recovery and le after thirty-two requests carrying recoveries, which is the bounded-cardinality promise stated as an assertion rather than a convention. * docs(devlog): record lane C2 and refresh the deferred dispositions Each item that did not land carries the reason that is true against current dev, not the one written a day ago. #3748's blocker is now narrower and more useful than "parallel store": the recorder does not yet record why a request finally failed, so there is nothing closed to group by. #3983's emission path turns out not to be ephemeral, because stderr is redirected to the service log under both launchd and systemd. #5063 has a concurrent-append data-loss window that the rename cannot see.

…contract #5063 proposed retention on the canonical ledger, which is the right architecture: the alternative is a projection that hides rows the ledger still has, and that is a second retention policy. What its implementation could not promise is that a row appended between its size snapshot and its rename survived -- it captured a size, copied a suffix, and renamed over whatever was there. Its own concurrency test performed two sequential calls and said so. Two things close that here. The append is synchronous and the compaction runs inside the same call stack, with no await between the append and the publication, so no in-process append can interleave; a second server on the same home cannot append at all, because it is refused by the existing ledger-owner lease at startup, which is why the hook is installed after ownership rather than before. And validateBeforeRename re-opens the target immediately before the rename and refuses unless identity, size and revision metadata are byte-for-byte what was copied -- so an append from anywhere else aborts the replacement rather than losing the row. Both the original file and that append survive, and the next append retries from a fresh revision. A test drives exactly that window through an injected hook, because a contract nothing can drive is a contract nobody has checked. Publication goes through the shared atomic writer rather than a hand-rolled temp lifecycle, which is where the exclusive private temp, the identity assertions, the platform-aware replace and the residual cleanup already live. The writer gains a streaming form so the retained span is copied in bounded chunks instead of held in memory as one string, and that form fsyncs the temp before the rename and does not swallow the failure: a replacement whose replacement is not on disk can lose the rows it was meant to keep. Rows are copied byte for byte and never parsed or re-serialized. A retention pass that understood the row shape would silently drop every field it was written before, which for this branch would mean the failure stage and cause it just added. The invalidation half was missing entirely from the original. Deleting rows invalidates three readers that do not watch the file: the 2,000-entry Logs ring, which otherwise keeps serving rows the ledger no longer has until eviction or a restart; the retained usage aggregate and failure projection, whose checkpoints now point past a boundary that moved; and the request-history index, whose source identity changed. All three are discarded after a replacement. This does NOT close #5063. The Usage-page control it also asks for is not here: this branch may not build or run the GUI, so it cannot produce the screenshot that gate requires, and shipping an unverifiable control is worse than shipping the policy the control would set. The limit is settable in config.json today and the docs say so. Co-authored-by: Vocllum <149675937+Vocllum@users.noreply.github.com>
