Agent Signup Phase 1b — close AI-spend and mail paths before any door opens

[2witstudios]

Agent Signup Phase 1b (epic q6nb94aq0ymvfslr11nqobjr, phase i9dce2tbsnvsmkllojcfg23x). An independent review of Phases 0–1 found paths that would give an agent free AI, a Stripe customer, or mail to its reserved address as soon as a sign-in door opens. This PR closes them. Phase 2 must not start until this merges. One commit per leaf; each leaf's task page has the full evidence, including mutation output.

Leaf 1 — workflow runs are credit-gated inside executeWorkflow ([D-33]) · 278746938

• The gate and hold now live inside executeWorkflow. They key on createdBy, run after the run claim and before any dispatch, size the hold by ai-step count, and release it in finally. A refusal fails the run with AI credit gate denied: <reason>, and createAIProvider/generateText are never called.
• Before this, the manual run route, the workflows cron, the task-triggers cron and the task-completion helper ran with no gate. The webhook, calendar and zoom executors used to gate themselves. They now pass only their daily-cap setting (creditGate) to the executor, so a run is never held twice.
• lib/workflows/core/workflow-gate-options.ts is a pure function that sizes the gate. If a caller passes no setting, the tier daily cap applies.
• The gate-callsites.guard.test.ts guard now lists all 7 entry points. It checks that the gate runs before dispatch and the hold is released in finally, and it fails if an entry point calls canConsumeAI/releaseHold itself.
• D-33 is still open. If it's answered A, this commit rebases onto the master hotfix and only the agent-specific test is kept.

Leaf 2 — no Stripe customer for an agent on any path · 4520910ae

• New @pagespace/lib/billing/stripe-customer-eligibility (100% coverage threshold). Both getOrCreateStripeCustomer copies (web and admin) refuse an agent before any Stripe call, and UserForCustomer now requires accountType. create-subscription, create-credit-topup, dedicated app hosting and admin gift-subscription map the refusal to 403. billing-address refuses directly.
• A monorepo source guard fails if customers.create( appears outside the 4 listed sites, or before their agent refusal.

Leaf 3 — one allowance function; billing-off parity; fail closed · f8f16deaf

• Every grant amount now comes from allowanceGrantCents({tier, accountType, kind}): the starter grant, the gate-side comped reset and invoice.paid. It returns 0 for an agent. starterGrantCents delegates to it, so the Phase 0 contract and tests are unchanged. The rollover arithmetic is the pure computeRefill.
• With billing off, hasSpendableBalance refuses an unclaimed agent through billingOffAgentGate.
• readGateAccount throws GateAccountNotFoundError when there is no users row. canConsumeAI turns that into a needs_init refusal (no hold is taken), hasSpendableBalance answers false, and the balance display adds no starter grant.

Leaf 4 — reserved domain sealed on invite routes; sendEmail reports suppression · 6a6d98b5d

• The drive-member invite, page share-invite, connection invite and admin magic-link send routes now apply notAgentReservedEmail and return each route's normal validation error. The list of inbound sites goes from 5 to 9.
• sendEmail returns sent | disabled | suppressed. The pending-invite senders pass that result through, and all three invite routes undo a suppressed send the same way they undo a failed one.

Review follow-ups · 97cb71e, cdeab50

• 97cb71e: CI typecheck TS18048 in the new dedicated route test (test-only fix).
• cdeab50 (CodeRabbit round 1): GET /api/stripe/customer and GET /api/stripe/billing-address refuse an agent with 403 before any Stripe read. executeWorkflow awaits releaseHold in finally. The Stripe creation guard checks every customers.create call in a listed site. Claimed-agent owner billing is left to Phase 4 (ADR 0007 Decision 8: resolveBillingPayer at the three billing seams only).

Independent review round · ad627a0, 2f76409, 6887d8e, 2682397

An internal review overrode PR_READY on cdeab50. Each fix was written RED-first and mutation-checked by line index.

P1-1 regression: calendar occurrence lost on a refusal (ad627a0). executeWorkflow claimed the workflow_runs row before the credit gate, so a refusal finalized an error row. The calendar cron only re-discovers occurrences with no run row, so the meeting's run was lost for good. Choice: the gate now runs before the claim. This keeps the calendar claim race-safe: the workflow_runs partial unique index is still the one atomic single-running guarantee, and a concurrent gate winner that loses the claim just releases its hold (tested). A throw inside the gate also returns before any row is claimed.

P1-2 refusal semantics for scheduled runs (ad627a0).

• New pure @pagespace/lib/billing/classify-gate-refusal (100% threshold): too_many_in_flight and daily_cap_exceeded are transient; out_of_credits, requires_funding and needs_init (which a missing users row maps to) are terminal.
• New pure shouldRetryRefusal (web workflows/core/refusal-retry.ts): retry only if the refusal is transient, the occurrence time exists, and it is at most 24h old.
• executeWorkflow returns refusal: {reason, kind, retry}. When retry is true it writes no run row. Otherwise it writes one error run with AI credit gate denied: <reason>.

Source	retry (transient, within 24h)	not retry (terminal, or past 24h)
Calendar cron	no row, so re-discovered next tick; counted as deferred	error run recorded; the occurrence ends
Task-triggers cron	claim released (lastFiredAt: null), trigger stays enabled, reason in lastFireError; deferred	trigger disabled with the reason (existing one-shot semantics)
Workflows cron	nextRunAt kept, so the slot fires next tick; deferred	error run recorded, advances to the next slot, stays enabled
Task-completion helper	trigger stays enabled, claim released, nextRunAt = completion instant, reason in lastFireError; the task-triggers cron runs it next tick with the completion task context and the original occurrence time, and a success disables it like a first-time success (e6482d60c)	disabled with the reason (unchanged)

Follow-up from a second independent review (0806c0c33).

• Retry now depends on the source, not the timestamp. Only calendar occurrences, task triggers (due-date and completion) and cron workflows are ever re-fired. A transient refusal on a webhook or manual fire is recorded; before, a webhook's fresh triggerAt read as retryable and the event was dropped.
• A throw from the gate itself follows the same bound. A rescheduled source within 24h keeps no row and retries; otherwise one error run is recorded, so a calendar occurrence is never re-discovered forever.
• Completion fires pass creditGate: { skipDailyCap: true }, the same policy as the cron that retries them.
• The task-triggers cron ends a completion retry whose task was reopened (Task no longer completed) instead of running the workflow.
• Mutations: allowing any source to retry ⇒ 2 red; never recording a thrown gate ⇒ 1 red; always recording it ⇒ 1 red; dropping skipDailyCap on the helper ⇒ 1 red; removing the reopened check ⇒ 1 red.
• Not changed (pre-existing, run history only): two overlapping calendar ticks can still run one occurrence twice (the unique index only covers status='running'), and refusals can record duplicate error rows.

P2-3 manual run (ad627a0). POST /api/workflows/[id]/run maps a refusal through creditGateErrorResponse (402 requires_funding + claim_url, 429 caps, 402 out of credits). It does not advance nextRunAt and does not audit a run.

P2-4 Zoom AI bypass (2f76409). generateTranscriptSummary and extractActionItems now go through withZoomAiCredit: canConsumeAI on connection.userId with skipDailyCap (as the zoom trigger executor does), hold released in finally. A refusal returns an empty enrichment, and the transcript page is still created. A new guard fails if any createAIProvider caller neither gates credit in the same file nor is listed with its upstream gate. The listed files are memory cron (paying tiers only), chat compaction, ask_agent (runs inside a gated parent) and the provider factory itself.

P2-1 Stripe linking (6887d8e). handleCheckoutCompleted skips reserved agent addresses and links only accountType = 'human' rows. The Stripe source guard now also fails on any non-null stripeCustomerId write outside the listed sites or before their agent refusal. Control-plane validateEmail (tenant creation and billing checkout) refuses the reserved domain like a malformed address.

P2-2 step-up (2682397). requestMagicLinkStepUp returns EMAIL_UNDELIVERABLE on a suppressed send, and the request route answers 422 step_up_email_undeliverable without auditing a challenge. The unreachable token expires on its own.

Known non-deliveries to agents (unchanged by design; each send is suppressed, not rolled back): lib/services/notification-email-service notification emails, lib/services/broadcast/core + transactional-engine broadcasts, web/lib/billing/send-payment-receipt-email receipts, web/lib/forms/send-form-notification, web/app/api/feedback, web/lib/auth/send-verification-email, and the web magic-link-adapters + admin magic-link send (both already refuse the reserved domain on input).

P2-5 not done. A missing users row keeps the needs_init 402 body. credit-gate-response.test.ts deliberately pins needs_init → 402, so changing it is not the trivial change the review allowed for.

Mutation evidence (line index, restored after each).

• classify: return 'transient' → 'terminal' ⇒ 2 red; return 'terminal' → 'transient' ⇒ 3 red.
• retry window: <= → < ⇒ 1 red; return true ⇒ 1 red.
• executor: dropping if (retry) return refused ⇒ 1 red; a stub refusal in place of recordRefusal ⇒ 3 red.
• completion helper (e6482d60c): retry branch off ⇒ 1 red; nextRunAt: null ⇒ 1 red; triggerAt: null ⇒ 2 red.
• task-triggers retry branch off ⇒ 1 red; workflows cron advancing on retry ⇒ 1 red; calendar deferred branch off ⇒ 1 red; run-route refusal mapping off ⇒ 2 red.
• Zoom helper bypassed ⇒ 3 red; zoom refusal off ⇒ 1 red.
• Webhook human filter removed ⇒ route test + guard red; reserved check removed ⇒ route test + guard red; non-null stripeCustomerId write added above the helper's refusal ⇒ guard red.
• control-plane reserved check removed ⇒ 1 red; step-up suppression check removed ⇒ 1 red.

Local harness note. stripe/webhook/__tests__/route.test.ts "still acks 200 … buyer lookup for the receipt throws" fails under the local source-alias config identically on the unchanged route (verified against cdeab50's route), so it is a harness artifact; CI is the authority.

Verification

• Local runs were single test files only (machine rule), all green: workflow suite (12 files), Stripe suite (web 9 files, admin 2), billing suite (credit-pricing/core/gate/funding/balance, has-spendable-balance, gate-account, credits-flow, app-hosting router), invite/email suite (3 routes, email-service, notification-email-service, admin magic-link, reserved-email-sites).
• Mutation checks were done by line index; the output is on each leaf's page. Removing the executor gate turns 4 tests red. Removing the web helper's Stripe refusal turns 4 red, including the create-credit-topup agent test that runs the real helper. Removing the allowance function's agent branch turns 10 red. The suppressed-send undo, the reserved-email refine and the fail-closed paths each turn 1–2 red.
• typecheck/lint/knip deferred to CI (run 35243062672 on 0806c0c; previous head e4d28d1 fully green on 35237548013). No automatic CI runs for PRs into pu/agent-signup, so the run was dispatched on this head.

📝 Walkthrough

Walkthrough

The PR adds agent Stripe-customer refusal handling, reserved-email validation, explicit email outcomes, centralized workflow credit gating, and account-aware billing safeguards. It also adds tests for routes, billing logic, workflow execution, and source guard conditions.

Changes

Agent billing and email controls

Layer / File(s)	Summary
Stripe eligibility and route handling packages/lib/src/billing/stripe-customer-eligibility.ts, apps/*/src/lib/stripe-customer.ts, apps/*/src/app/api/stripe/..., apps/*/src/app/api/app-hosting/...	Agent accounts are refused before Stripe customer operations. Affected billing and subscription routes return 403 responses.
Reserved-email delivery and validation packages/lib/src/services/email-service.ts, packages/lib/src/services/notification-email-service.ts, apps/web/src/app/api/{connections,drives,pages}/..., apps/admin/src/app/api/auth/magic-link/send/...	Email operations return explicit delivery outcomes. Reserved agent addresses fail validation, and suppressed invitation sends roll back pending invitations. Step-up magic-link requests report undeliverable email separately.

Centralized workflow credit gating

Layer / File(s)	Summary
Credit policy and acquisition apps/web/src/lib/workflows/core/*, apps/web/src/lib/workflows/workflow-credit-gate.ts, apps/web/src/lib/workflows/workflow-executor.ts, related tests	Workflow execution derives credit requirements, reserves credit before claiming a run, returns typed refusal data, and releases holds after execution.
Scheduled, webhook, and Zoom entry points apps/web/src/app/api/cron/..., apps/web/src/lib/workflows/..., apps/web/src/lib/webhooks/..., apps/web/src/lib/integrations/zoom/...	Entry points pass daily-cap policies to shared execution or use withZoomAiCredit. Transient scheduled refusals remain eligible for retry and are reported as deferred.

Account-aware billing safety

Layer / File(s)	Summary
Account resolution and missing-account handling packages/lib/src/billing/gate-account.ts, gate-account-not-found.ts, credit-balance.ts, related tests	Missing users rows raise GateAccountNotFoundError. Balance and gate paths fail closed for missing accounts.
Allowance and refill rules packages/lib/src/billing/credit-pricing.ts, credit-core.ts, credit-funding.ts, credit-gate.ts, related tests	Agents receive zero starter and refill allowance. Agent refills skip ledger grant creation. Billing-off checks distinguish unclaimed agents from claimed agents.

Block agent reads before Stripe retrieval.

GET does not call assertMayHoldStripeCustomer(user). An agent row with a retained stripeCustomerId therefore reaches stripe.customers.retrieve and receives the customer email, address, and default payment method. The existing helper protects creation paths, not this GET route.

Call assertMayHoldStripeCustomer(user) after the user lookup and map AgentStripeCustomerRefusedError to HTTP 403 before the customer-ID branch.

Review round 1 (CodeRabbit, 4 inline + 1 outside-diff), all addressed in cdeab50:

• Outside diff, GET /api/stripe/customer (CWE-200): fixed. GET refuses an agent with 403 before a stale stripeCustomerId can be retrieved. GET /api/stripe/billing-address had the same read path and gets the same refusal. New tests for both; removing the customer GET refusal turns its test red.
• Inline threads: guard checks every create call (fixed), awaited hold release (fixed), owner-as-payer (Phase 4 per ADR 0007 Decision 8, no change), schema/core import (core doesn't export users, no change). Details on each thread; fixed threads are left open for you to verify.

Independent review round: summary for reviewers (head e6482d6; the full detail and mutation evidence are in the PR body under "Independent review round")

An internal review overrode the earlier PR_READY on cdeab50. Every fix below started from a failing test and was mutation-checked by line index.

• P1-1 gate before the run claim (ad627a0). executeWorkflow used to claim the workflow_runs row before the credit gate, so a refusal left an error row and the calendar cron (which only picks occurrences with no row) lost the meeting run. The gate now runs first. The claim is still the single atomic running guard, and a gate winner that loses the claim releases its hold.
• P1-2 refusal semantics (ad627a0, e6482d6).
  • New pure classifyGateRefusal in lib (100% coverage): the in-flight and daily caps are transient; out of credits, requires_funding and needs_init are terminal.
  • New pure shouldRetryRefusal: transient, has an occurrence time, and at most 24h old.
  • A retryable refusal writes no run row. Every other refusal records one error run with the reason.
  • Calendar cron: the occurrence is found again next tick. Workflows cron: the slot is kept. Task-triggers cron: the claim is released and the trigger stays enabled. Completion triggers are handed to the task-triggers cron (nextRunAt = completion instant, same 24h bound).
  • Terminal refusals keep existing failure semantics, except recurring workflows advance to their next slot and stay enabled.
• P2-3 manual run (ad627a0). A refusal returns 402 requires_funding (with claim_url) or out of credits, or 429 for the caps. The schedule doesn't advance and no run is audited.
• P2-4 Zoom AI bypass (2f76409). Transcript summary and action items now check credit on the connection owner (skipDailyCap, hold released). A new guard fails on any createAIProvider caller without a credit gate, unless it is listed with its upstream gate.
• P2-1 Stripe (6887d8e). The checkout webhook never links a customer to a reserved agent address and links only human rows. The source guard now also flags non-null stripeCustomerId writes. Control-plane validateEmail refuses the reserved domain.
• P2-2 step-up (2682397). A suppressed confirmation email returns EMAIL_UNDELIVERABLE, and the route answers 422.
• Not changed: P2-5 (needs_init → 402 is pinned by an existing test). Other sendEmail callers are listed in the PR body as known non-deliveries to agents.

CI run 35233492530 on e6482d6: E2E ✅. Unit Tests ❌ and Lint & TypeScript ❌ both failed on the same error: control-plane TS2307 for @pagespace/lib/auth/agent/reserved-email. control-plane compiles with moduleResolution: node, which ignores the exports map, so the new subpath needed a typesVersions entry like every other lib subpath control-plane imports. That error stopped typecheck at 9 of 20 tasks, so web typecheck and knip did not run. Fixed in 073bb39; re-dispatched as run 35234817647.

CI run 35234817647 on 073bb39: E2E ✅. Two test-only failures, both fixed in e4d28d1:

• Lint & TypeScript failed on web#typecheck TS2352/TS2493 in task-trigger-helpers.test.ts: mockSet.mock.calls is typed as an empty tuple. Fixed in 9936c36 with an explicit cast. Typecheck stopped at 19/20, so knip did not run.
• Unit Tests: 1353 files passed, 1 failed. My new webhook test JSON.stringify'd the checkout WHERE, which is a real, circular drizzle SQL in CI. Fixed in e4d28d1 with a structural match. Removing the human filter still turns it red.

Re-dispatched as run 35237548013.

A second independent review of the refusal-semantics round found no P1s and four P2s, all fixed in 0806c0c:

1. A transient refusal on a webhook fire was dropped with no run row: webhooks pass a fresh triggerAt, which read as retryable. Retry now depends on the source; only calendar, task-trigger and cron runs retry.
2. A thrown gate left a calendar occurrence re-discovered with no limit. It now follows the same 24h bound, then records one error run.
3. A completion fire used the tier daily cap while its cron retry skips it. Both paths now skip it.
4. The cron retried a completion trigger even after its task was reopened. It now ends the trigger with Task no longer completed.

Each fix was written RED-first and mutation-checked; details are in the PR body. CI run 35243062672.

Reject a retry after the task is completed again.

This check only tests whether completedAt is non-null. If the task is reopened and completed again before this retry, the stale completion trigger executes against the new completion. A new completion trigger can then execute the workflow a second time.

Compare task.completedAt with the original occurrence in trigger.nextRunAt, or persist an explicit completion occurrence identifier.

Proposed fix

 if (trigger.triggerType === 'completion') {
   const task = taskMap.get(trigger.taskItemId);
-  const skipReason = !task ? 'Task not found' : !task.completedAt ? 'Task no longer completed' : null;
+  const skipReason = !task
+    ? 'Task not found'
+    : !task.completedAt
+      ? 'Task no longer completed'
+      : task.completedAt.getTime() !== trigger.nextRunAt.getTime()
+        ? 'Task completion occurrence changed'
+        : null;

Parse model output as unknown.

JSON.parse returns any, so parsed is inferred as any despite strict mode. Array.isArray(parsed) permits item to remain any while reading text and assignee. This violates the mandatory no-any guideline at the model-output boundary. This is an essential type-safety refactor, not a major runtime issue.

Proposed fix

-  const parsed = JSON.parse(jsonText);
+  const parsed: unknown = JSON.parse(jsonText);

   if (!Array.isArray(parsed)) return [];

   return parsed
-    .filter((item): item is ActionItem => typeof item?.text === 'string')
+    .filter((item: unknown): item is ActionItem =>
+      typeof item === 'object'
+      && item !== null
+      && 'text' in item
+      && typeof item.text === 'string'
+    )

Reject disabled email delivery.

sendEmail also returns { status: 'disabled' } in on-prem deployments. This condition treats that outcome as success, so the client reports that a magic link was sent although no link exists. Reject every non-sent outcome, or map disabled to a separate client error.

Proposed fix

-  if (outcome.status === 'suppressed') return { ok: false, error: { code: 'EMAIL_UNDELIVERABLE' } };
+  if (outcome.status !== 'sent') return { ok: false, error: { code: 'EMAIL_UNDELIVERABLE' } };
