  "seed": "Please review this plan thoroughly in HOLD SCOPE mode. As you go, write your plan-mode plan to /owned/plan.md (use Edit/Write to that exact path).\nProceed directly to the requested CEO review; skip the optional /office-hours prerequisite.\nFinish after this CEO review; I will handle subsequent reviews manually.\n\n# Plan: Payment Processing Integration\n\n## Existing contracts retained\nThe approved motivation is to move payment orchestration out of the prior\nlibrary-adapter handler into application-owned code while retaining the\nexisting payment and receipt product behavior. The shared dispatcher remains\navailable; the proposed bypass below is still an architectural choice to review.\nThe existing ingress middleware verifies the Stripe signature against the\nraw request body and rejects invalid signatures before invoking handlers.\nThe existing ingress forwards only `payment_intent.succeeded` events to\nthis handler; other Stripe event types are acknowledged without invoking it.\nThe existing payload adapter exposes `event.data.object.metadata.user_id`\nas `request.params.userId`. This params object is the parsed body-data map,\nnot URL query/path parameters; all users share one webhook URL.\nThe adapter acknowledges missing, nil, or empty user_id metadata with\nHTTP 200 and an event-correlated warning before invoking this handler.\nFor every nonempty external string it performs no SQL-format validation.\nThe adapter forwards that external string unchanged. It does not cast,\nescape, or SQL-sanitize it; a valid signature does not make it safe for SQL.\nUser IDs are opaque TEXT values, including punctuation and Unicode. The\nlookup has no integer/UUID cast or ID-format restriction; every nonempty\nstring is a valid identifier representation.\nAn existing ingress ownership guard checks the PaymentIntent ID against\nits stored opaque user-ID binding before invoking the handler. A mismatch\nis acknowledged with HTTP 200 and an event-correlated warning. This is an\nidentity comparison, not SQL-format validation; the adapter still forwards\nthe original string unchanged.\nThe existing webhook event guard deduplicates deliveries by Stripe event ID,\nand an existing per-user lock serializes payment updates.\nThe event guard acquires the existing per-user lock before checking the\ncommitted completion marker, and rechecks after any lock wait. It holds\nthat lock through the handler and completion bookkeeping; an overlapping\ncompleted duplicate does not invoke the handler.\nThe new handler runs inside those unchanged guards; this plan does not\nreplace signature verification, event deduplication, or update locking.\nThe existing user update assigns payment_status=paid and the payment intent\nID; it does not increment a balance or counter. Repeating the same payment\nintent assigns the same values, independently of the event-ID guard.\nThe existing lookup-result guard acknowledges unknown/deleted users with\nHTTP 200, logs the event, and stops before user updates or email fan-out.\nThe retained recipient-policy helper treats a nil or empty email address as\nskipped_missing_address: payment processing continues normally, and no mail\nclient call is attempted. It persists an event/user/PaymentIntent-correlated\nskip record, emits a structured warning, and increments the existing counter.\nThe existing notification runbook already covers that skip result: correct\nthe account address, then retry only its recorded notification using the\nsame PaymentIntent idempotency key. It never replays the payment for this case.\nThat recipient policy does not catch failures from sends to nonempty addresses;\nthe shared mail client still rethrows those exceptions to this handler.\nAccount deletion uses the same per-user lock. The handler holds it from\nlookup through update and inline email, so deletion either precedes lookup\n(the existing unknown/deleted-user path) or follows the handler; it cannot\nremove the user between lookup and update.\nThe ingress wrapper already logs event IDs, outcomes, and durations, with\nalerts for failed webhook processing. Those controls remain in place.\nThe existing DB and mail clients attach the adapter user ID and event ID\nto outcome traces, including update success and email delivery success or\nfailure. These shared clients rethrow exceptions unchanged; tracing does\nnot rescue email errors or change the inline email call below.\nThe shared mail client also publishes its delivery failure rate to the\nexisting dashboard and tested on-call alert, including caught exceptions.\nThe existing incident runbook uses the correlated DB and mail outcomes to\ndistinguish committed payments from failed notifications. It directs on-call\nto check provider status and retry only the failed notification through the\nexisting notification retry procedure, never replay the payment blindly.\nDB lookup/update exceptions propagate to that ingress wrapper, which logs\nthe failure and returns HTTP 500 so Stripe retries the event. The existing\nevent-ID dedup guard records completion only after the database transaction\ncommits; failed or rolled-back database attempts remain retryable.\nThe deployment already has a handler feature flag and a documented, tested\nrollback to the prior handler; this change uses that existing rollout path.\nThat documented manual rollout checklist already requires a staging\npayment-event replay for this handler and verification of the user update,\nemail delivery, and correlated outcome trace before enabling it broadly.\nThis is manual deployment verification, not automated handler regression\ncoverage; no new automated tests are planned in the Tests section below.\nThe existing notification contract sends one payment receipt per PaymentIntent,\nincluding a summary of the user orders. With zero orders it still sends one\nreceipt with an empty order summary; the order loop is data loading, never\none email or payment update per order. These product semantics are retained.\nThe shared mail client already derives a provider idempotency key from that\nPaymentIntent ID. The provider durably suppresses duplicate successful sends\nfor the same key across process crashes, webhook retries, and manual retries.\nBefore rethrowing a failed or timed-out send, that client durably records the\nnotification attempt for the existing retry procedure. The dashboard and\non-call alert already monitor failed-notification age and backlog after an\noutage clears, as well as failure rate; the runbook retries those records.\nThe existing mail-client deadline is one second, enforced by cancellation\nof the provider request with no inline retries. It raises MailTimeout on\nexpiry. The retained DB/ingress deadlines bound their combined work to two\nseconds, leaving headroom inside the existing ten-second webhook deadline.\nNeither deadlines nor retry records catch the mail exception for this handler;\nthe shared client still rethrows it to the inline caller described below.\nEvery existing event-correlated outcome trace includes the active handler\nidentity (prior or new), so rollout attribution is already available.\nIf a separate handler class is retained, its already-approved name is\n`Webhooks::StripePaymentWebhookHandler` in the application-owned namespace,\nnever the Stripe library namespace. This naming choice is settled; whether\nto add a separate implementation or reuse WebhookDispatcher remains open.\n\n## Architecture\nWe're adding a new `StripePaymentWebhookHandler` class that will handle Stripe webhooks.\nThis bypasses the existing `WebhookDispatcher` module — we want a clean\nnamespace separation.\n\n## Database access\nThe new endpoint reads `request.params.userId` directly into a raw SQL\nfragment for the lookup query.\n\n## Webhook fan-out\nOn payment success we update the user record AND fire a notification email.\nBoth happen inline; no error handling on the email leg.\n\n## Tests\nNone planned. We'll rely on the existing integration suite catching regressions.\n\n## Performance\nEach webhook lookup hits the database for the user, then fetches each\norder in a loop.",

A notification failure is reported to Stripe as a payment-processing failure. The payment\n   IS committed; the 500 is a lie about the thing Stripe cares about.\n2. Two retry mechanisms fight over one send: Stripe's webhook retry and the existing\n   notification retry procedure (runbook L49-51, L66-69, L88-91). Each Stripe retry appends a\n   new failed-attempt record, inflating the backlog the dashboard alerts on.\n3. During a total mail-provider outage every `payment_intent.succeeded` returns 500. Stripe\n   marks the endpoint failing and can disable it after sustained failure. A mail outage\n   becomes a payment-status outage. Inversion: this is the single change most likely to\n   cause an incident.\n4. The \"failed webhook processing\" alert fires for a condition the mail failure-rate alert\n   already covers, so on-call gets two pages for one cause.\n\nCommitments:\n- ordering [approved by product contract L40-42, L81-84]: current=update then send; A=update commits, then send; B=same; C=update commits, then enqueue\n- mail exception handling [pending]: current=none (propagate); A=rescue named mail exceptions (MailTimeout + the client's send-failure class) after commit, log structured `notification_failed` with event/user/PI correlation, return 200; B=propagate → 500; C=enqueue send to a background job after commit\n- DB exception handling [approved, L70-73]: current=propagate → 500 → retry; A=same; B=same; C=same\n- missing-address path [approved, L45-51]: current=recipient-policy skip; A=same; B=same; C=same\n- retry ownership [approved runbooks, L49-51, L66-69, L88-91]: current=notification retry procedure; A=notification retry procedure only; B=Stripe retry AND notification procedure; C=job retry AND notification procedure\n\n| Option | Summary | Effort | Risk | Pros | Cons | Reuse / verification |\n|---|---|---|---|---|---|---|\n| A.

Scope: routing path only; class name, guards, flag mechanism unchanged |\n| R2 DB lookup (user) | PLAN.md L21-26, L110-112: adapter forwards raw TEXT unchanged, no sanitization | Raw SQL fragment from `request.params.userId` | A: `userId` passed as a bound parameter through the existing DB client; no format validation added | approved | D4 answer = A. Scope: query construction only; opaque-TEXT contract and unknown-user guard unchanged |\n| R3 Email leg (user) | PLAN.md L52-53, L60-73, L85-97, L114-116: mail client rethrows; ingress returns 500 on exception | Inline send, exception propagates to ingress | A: update commits first; send wrapped in `rescue MailTimeout, <client send-failure class>` only; structured `notification_failed` log/trace with event/user/PI; HTTP 200; retries owned by existing notification procedure | approved | D5 answer = A. Scope: mail exception handling only; DB exceptions still propagate → 500; recipient policy unchanged; no job queue |\n| R4 Tests (user) | PLAN.md L76-80, L118-119: manual staging replay only | No automated tests | A: handler unit tests (cases 1-9) + dispatcher flag test (10) + ingress-level integration with flag on (11-12); manual staging replay still required | approved | D6 answer = A. Scope: automated coverage for the new handler and its wiring; does not alter the rollout checklist |\n| R5 Order loading (user) | PLAN.md L81-84, L92-95, L121-123: 2s DB budget; loop is data loading | Per-order fetch loop | see 0D | unresolved | |\n| M Mode (user) | User request: \"HOLD SCOPE mode\" | HOLD SCOPE | n/a | approved | User request line 1: \"review this plan thoroughly in HOLD SCOPE mode\" |\n\n## Step 0D. Alternatives (pending)\n\n### R5. Order loading: per-order fetch loop\n\nTrace: lookup user (1 query), then N queries for N orders, all inside the retained 2-second\nDB+ingress budget (L92-95), and all before the update and send. Order count is unbounded per\nuser. At some N the loop exceeds the budget; the DB deadline raises; the exception propagates\n(approved DB path) → HTTP 500 → Stripe retries → same N, same timeout, every retry for 72h.\n\n```\n  N orders:   1    10    100    1000\n  queries:    2    11    101    1001      (1 user + N orders)\n  at ~2ms each:  4ms  22ms  200ms  2.0s  ◄── budget exhausted; deterministic failure\n```\n\nThe user who has bought the most from you is the one whose payment never marks paid. That is\nthe worst possible failure distribution. The retained contract (L81-84) needs the orders only\nto build the summary in one receipt; nothing requires N round trips.\n\nCommitments:\n- receipt semantics [approved, L81-84]: current=one receipt, order summary, empty summary at zero orders; A=same; B=same; C=same\n- order query shape [pending]: current=N per-order fetches; A=one query `WHERE user_id = ?` (bound parameter, same DB client as R2); B=keep loop; C=one query plus a hard cap on rows in the summary\n- deadline behavior on DB timeout [approved, L70-73, L92-95]: current=propagate → 500; A=same; B=same; C=same\n\n| Option | Summary | Effort | Risk | Pros | Cons | Reuse / verification |\n|---|---|---|---|---|---|---|\n| A. Single batched query (recommended) | Fetch all orders for the user in one bound-parameter query | S (human ~1h / CC ~2 min) | low | query count constant (2) regardless of N; removes the deterministic-timeout class; same receipt output | very large N still returns a large result set (bounded by row size, not round trips) | reuses DB client; test: 0, 1, 250 orders → one orders query, identical summary |\n| B. Keep loop (as planned) | N per-order fetches | none | high | zero change | high-order-count users fail forever; each Stripe retry repeats N queries under lock | none |\n| C. Batched + summary cap | One query with LIMIT and a \"and K more\" line | S-M | low | bounds payload for extreme N | changes receipt content, which L81-84 says is retained; product decision, not an engineering one | would need product approval |\n",
