PAY-003A11 — Persist Checkout paidAt from admitted Event evidence #586
Description
Outcome
When a newly admitted Checkout payment transition fills a missing paidAt, persist the already admitted outer Stripe Event time. Do not invent financial-evidence time from the webhook delivery/server clock. Preserve every existing paidAt value.
This is an atomic child of #106 and follows released PAY-003A10 / #584.
Defect
Exact main 1c85ec08c274ad9077118d4daf3a6ac9dad118bd validates every supported Checkout Event created value before target work. Three branches in successfulPaymentTransition still use:
paidAt: record.paidAt || Timestamp.now()
The affected branches are ordinary payment confirmation, payment observed after a partially-refunded/refunded state, and payment observed after a fulfilled/transferred state. A delayed or retried webhook can therefore persist receipt time as though it were provider payment evidence.
Priority and dependency state
- Priority: P0 payment correctness/security. Canonical financial evidence must not be fabricated from delivery time.
- Higher exposure: the React Router P0 remains blocked by AUTH-MAIL-002C2A — Bind verification results to the current identity service #571 active ownership of a required migration-test path.
- Dependencies: PAY-003A8/PAY-003A8 — Reject invalid Checkout and refund Event timestamps before target work #572, PAY-003A9/PAY-003A9 — Reject invalid refund Charge timestamps before target work #578, and PAY-003A10/PAY-003A10 — Reject impossible refund Charge/Event chronology #584 are complete, merged, exact-main verified, and claim released.
- Conflicts: live issue, pull-request, branch, and path searches found no competing
paidAtclaim. Active AUTH-MAIL-002C2A — Bind verification results to the current identity service #571/MEMBERS-DIRECTORY-001 — Add a private opt-in officer photo directory #504 and draft Rollback: prepare exact pre-header Netlify artifact #462 are disjoint.
Invariant and transition order
A new supported Checkout Event retains the existing order:
- Processed Event replay.
- Outer Event realm.
- Checkout Session lifecycle admission.
- Explicit MPRC metadata schema.
- Valid outer Event-created integer and Firestore range.
- Target, ownership, and provider binding.
- Mode, money, payment-status, PaymentIntent, and predecessor-state rules.
- Branch-specific successful-payment transition.
- Only when that transition needs to fill a missing
paidAt, project the exact admitted Event second withTimestamp.fromMillis(event.created * 1000).
Existing paidAt remains authoritative. updatedAt, audit/action, processing, exception, and other operational times remain server/action-clock values. This adds no new Event admission or business outcome.
Exact implementation scope
functions/stripeWebhook.js- replace only the three missing-
paidAtreceipt-clock fallbacks insuccessfulPaymentTransition.
- replace only the three missing-
functions/stripeWebhook.test.js- one separately named
PAY-003A11 Checkout payment-time projectionblock plus minimum local helper reuse/addition.
- one separately named
STRIPE_COMMERCE_DESIGN.md- one separately named source-only PAY-003A11 section immediately after A10.
Required tests
- Trustworthy test-only RED on exact main: unseeded registration and order confirmations, with Event time distinct from the mocked server clock, must currently store the wrong time while retaining
payment_confirmed. - Registration and order completion project the exact admitted Event time.
- Delayed asynchronous success projects the exact admitted Event time.
- Payment observed after partially-refunded/refunded and fulfilled/transferred states projects the Event time without changing the existing branch outcome.
- Existing
paidAtis never overwritten. - Refund-first Charge-derived
paidAtremains preserved. - Exact replay remains first and does not repair historical records.
- Admitted epoch and maximum Event seconds project without off-by-one or local-clock substitution.
- Unpaid completion, failure, expiry, and paid-after-cancellation exclusions do not fabricate
paidAt. - Operational
updatedAt, audit, binding, ledger, and processing times remain server/action-clock values. - Complete webhook and Functions suites remain green.
Explicit exclusions
No Checkout Session-created validation or chronology; no current-clock freshness/skew policy; no already-processed or already-paid missing-time repair; no paid-after-cancellation policy change; no Charge or Dispute admission change; no provider/API-version proof or retrieval; no history reprocessing, migration, or backfill; no schema, Rules, index, package, or workflow change; no PAY-003B/C, reconciliation, alert, reservation, inventory, or outbox work; no officer procedure; no Firebase/Stripe deployment or configuration; no provider action; no production-data change; no payment/refund/dispute action; no live-behavior claim. Preserve active #571/#504 and draft #462 byte-for-byte.
Compatibility and migration
No schema, migration, backfill, dependency, API, or configuration change. Existing processed Events and existing paidAt values remain immutable. Historical records with receipt-clock values are not reprocessed or repaired.
Officer impact: None — this is a server-only distinction between provider evidence time and operational receipt time. It adds no officer screen, task, field, permission, approval, or available recovery step.
Officer documentation: None — the current money and release guides already prohibit manual financial-record repair and separate source, deployment, provider, data, and live proof. Engineering truth changes only in STRIPE_COMMERCE_DESIGN.md.
Deployment evidence: None at issue creation. Source/tests/merge will not be described as website publication, runmprc.com verification, Firebase deployment, Stripe/provider configuration, production-data change, payment/refund/dispute activity, or live-behavior proof.

paidAt, it now storesTimestamp.fromMillis(event.created * 1000)from the already admitted outer Event evidence. Ordinary confirmation, payment observed after refund, and payment observed after fulfillment/transfer retain their existing statuses, review flags, and outcomes. ExistingpaidAt, exact replay, already-paid no-repair behavior, excluded paths, operational clocks, and historical records remain unchanged.Review disposition: self-review and three independent exact-head reviews are GO with no remaining finding. Security/runtime verified admission, replay, bounds, bindings, state, operational clocks, logging, and no migration. Compatibility/test verified the trustworthy RED and mutant-sensitive 22-test matrix across both domains and all three source-line families. Documentation/backup-officer verified the complete source-only NOT LIVE handoff and the no-officer-guide conclusion.

The administrator merge path then merged the exact reviewed head. Its command reported a local worktree-switch failure because another checkout owns
main; remote verification proved the merge itself succeeded, the branch was deleted, and main/tree identity is exact.Deployment truth, kept separate:
