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 \u2014 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.", "captures": [ { "nativeCall": { "sessionId": "0ec85e47-4a55-4dee-a0b8-87a82de80e78", "toolUseId": "toolu_01Ddifun8k1gGmworhnQStvL", "questions": [ { "question": "D1 \u2014 Should the new handler bypass `WebhookDispatcher` or register through it?\nProject/branch/task: gstack-plan-count on main, reviewing PLAN.md (Payment Processing Integration) in HOLD SCOPE.\nELI10: Every Stripe webhook enters one front door (the ingress guards), then a dispatcher picks the handler.

Branch: `main`. Base branch: `main` (git-native fallback; no remote).\nMode: HOLD SCOPE (explicit user instruction; no mode question asked). Working plan = this file.\n\n## Context\n\nThe approved motivation (PLAN.md:8-11) is to move payment orchestration out of the prior library-adapter handler into application-owned code while keeping the existing payment and receipt behavior. Every ingress guard stays: signature verification, `payment_intent.succeeded` filtering, event-ID dedup, per-user lock, ownership guard, unknown-user guard, recipient policy, mail idempotency key, feature flag + rollback. The review target is the handler body itself: the four short sections of PLAN.md:105-123 (Architecture, Database access, Webhook fan-out, Tests, Performance).\n\n## Pre-review system audit\n\n- Repo is a review fixture: `CLAUDE.md`, `PLAN.md`, one commit, no stash, no TODO/FIXME, no TODOS.md, no docs/. No design doc, no handoff note. Brain digests cold. Prior learnings: 0.\n- Retrospective check: single commit, nothing to compare.\n- Frontend/UI scope: none (server-side webhook handler). Section 11 = no-UI skip.\n- Landscape (WebSearch; Aside unavailable): Layer 1 = verify signature on raw body, dedupe by event.id, 2xx after commit, replay in staging. Layer 2 = same plus \"events row before business logic\". Layer 3 = this plan inherits all of that from unchanged ingress guards; residual risk is inside the handler body only.\n\n## Step 0\n\n### 0A. Premise Challenge\n1. Right problem? Yes. Owning orchestration in app code is the standard shape; the library-adapter handler is the thing being retired. No simpler framing beats \"new handler behind the existing flag\".\n2. Outcome: same product behavior (status=paid, one receipt per PaymentIntent) from app-owned code. The plan reaches it directly, but three of its four implementation sections introduce regressions that the retained contracts explicitly warn about (PLAN.md:21-26 on SQL, :52-53 and :96-97 on mail rethrow, :81-84 on the order loop).\n3. Do nothing: orchestration stays in the library adapter. Pain is real but not urgent; there is no deadline pressure that justifies shipping the handler with the defects below.\n\n### 0B. Existing Code Leverage (mapped from PLAN.md contracts; repo code not available in this fixture)\n| Sub-problem | Existing code | Plan reuses it? |\n|---|---|---|\n| Signature, event-type filter, dedup, per-user lock, ownership guard | ingress middleware + event guard (PLAN.md:12-39) | Yes (unchanged) |\n| Missing/empty user_id, unknown user | adapter + lookup-result guard (:19-20, :43-44) | Yes |\n| Handler routing | `WebhookDispatcher` (:10-11, :105-108) | **No: bypassed. Open decision D1.** |\n| User lookup by opaque TEXT id | existing lookup (:24-26); no cast/format restriction | **No: raw SQL fragment. D2.** |\n| Receipt send + idempotency + failure record | shared mail client + recipient-policy helper (:45-53, :85-91) | Yes, but exception handling left to handler. **D3.** |\n| Order summary loading | per-order fetch loop proposed (:122-123) | **N+1. D5.** |\n| Regression coverage | existing integration suite + manual staging replay (:76-80, :118-119) | **No handler tests. D4.** |\n\nRebuilding: the handler class itself is the intended rebuild. Bypassing `WebhookDispatcher` is the only place the plan rebuilds routing that already exists; the plan itself marks that open (PLAN.md:102-103).\n\n### 0C. Dream State Mapping\n```\n CURRENT STATE THIS PLAN 12-MONTH IDEAL\n library-adapter handler ---> app-owned Webhooks:: all Stripe event handlers are\n orchestrates payment; StripePaymentWebhookHandler app-owned classes registered\n ingress guards app-owned behind existing flag; guards through one dispatcher, each\n unchanged; handler body has with unit tests + fixture replay;\n raw SQL, coupled mail, N+1, no raw SQL anywhere in webhooks\n no tests\n```\nDirection: toward the ideal on ownership, away from it on routing (bypass), safety (raw SQL), and test coverage. The four decisions below turn \"toward\" into \"toward on every axis\" without widening scope.\n\n### 0E. Mode provenance\nExplicit user instruction: \"review this plan thoroughly in HOLD SCOPE mode\" \u2192 HOLD SCOPE. No question asked, no question log.\n\n### 0G. HOLD SCOPE checks\n1. Complexity: 1 new class, est. 2-4 files (handler, registration/flag wiring, tests, possibly a query helper). Under the 8-file / 2-class threshold. No challenge.\n2. Minimum changes for the goal: the handler class + flag wiring. Nothing in the plan is deferrable without blocking the goal; no defer/keep questions raised.\n3. Stated invariants to keep (PLAN.md:7-103): all retained contracts. Repairs needed to meet them (D2, D3, D5) are in scope. D4 is completeness for new code, not expansion.\n\n## Decision ledger\n\n| ID and owner | Contract and evidence | Current | Proposed | Status | Exact approval and scope |\n|---|---|---|---|---|---|\n| D1 (architecture; owner: plan author) | PLAN.md:10-11, :100-108.

The plan adds a new handler and wires it around the dispatcher for \"clean namespace separation\". Namespace and routing are separate concerns: the class can live in `Webhooks::` and still be registered with the dispatcher. Two routes into payment handling means two places to keep the flag, the event filter and the guards in sync, and the fixture does not tell us whether any guard lives inside the dispatcher.\n\n**Stakes if wrong:** if a guard lives in the dispatcher, bypassing it silently drops signature/dedup/lock coverage for paid events; even if not, we carry two routing paths for the 12-month state.\n\n**Recommendation:** A because the settled name already gives namespace separation; the dispatcher gives one routing path and one place for the feature flag.\n\n**Completeness:** A=9/10, B=6/10, C=5/10\n\nA) Register `Webhooks::StripePaymentWebhookHandler` inside `WebhookDispatcher` (recommended). Effort S (human ~half day / CC ~10 min). Risk low. One routing path, flag lives where the prior handler's flag already lives, every ingress guard provably still in front. Pros: no second entry point to audit; rollout attribution (PLAN.md:98-99) stays on the existing trace; dispatcher tests cover routing. Cons: requires touching the dispatcher registration (one line); \"clean separation\" is achieved by namespace only, not by a separate route. Reuse: dispatcher, flag, traces. Verification: dispatcher routing test + handler tests (D4).\n\nB) Bypass `WebhookDispatcher`, wire the new class directly (as written). Effort S (human ~half day / CC ~10 min). Risk medium-high until the guard location is confirmed. Pros: no dispatcher edit; matches the plan text. Cons: second routing path to keep in sync with flag and event filter; unknown whether any guard is dispatcher-resident (must be verified in code before this is safe); 12-month state has two doors.

Branch: `main`. Base branch: `main` (git-native fallback; no remote).\nMode: HOLD SCOPE (explicit user instruction; no mode question asked). Working plan = this file.\n\n## Context\n\nThe approved motivation (PLAN.md:8-11) is to move payment orchestration out of the prior library-adapter handler into application-owned code while keeping the existing payment and receipt behavior. Every ingress guard stays: signature verification, `payment_intent.succeeded` filtering, event-ID dedup, per-user lock, ownership guard, unknown-user guard, recipient policy, mail idempotency key, feature flag + rollback. The review target is the handler body itself: the four short sections of PLAN.md:105-123 (Architecture, Database access, Webhook fan-out, Tests, Performance).\n\n## Pre-review system audit\n\n- Repo is a review fixture: `CLAUDE.md`, `PLAN.md`, one commit, no stash, no TODO/FIXME, no TODOS.md, no docs/. No design doc, no handoff note. Brain digests cold. Prior learnings: 0.\n- Retrospective check: single commit, nothing to compare.\n- Frontend/UI scope: none (server-side webhook handler). Section 11 = no-UI skip.\n- Landscape (WebSearch; Aside unavailable): Layer 1 = verify signature on raw body, dedupe by event.id, 2xx after commit, replay in staging. Layer 2 = same plus \"events row before business logic\". Layer 3 = this plan inherits all of that from unchanged ingress guards; residual risk is inside the handler body only.\n\n## Step 0\n\n### 0A. Premise Challenge\n1. Right problem? Yes. Owning orchestration in app code is the standard shape; the library-adapter handler is the thing being retired. No simpler framing beats \"new handler behind the existing flag\".\n2. Outcome: same product behavior (status=paid, one receipt per PaymentIntent) from app-owned code. The plan reaches it directly, but three of its four implementation sections introduce regressions that the retained contracts explicitly warn about (PLAN.md:21-26 on SQL, :52-53 and :96-97 on mail rethrow, :81-84 on the order loop).\n3. Do nothing: orchestration stays in the library adapter. Pain is real but not urgent; there is no deadline pressure that justifies shipping the handler with the defects below.\n\n### 0B. Existing Code Leverage (mapped from PLAN.md contracts; repo code not available in this fixture)\n| Sub-problem | Existing code | Plan reuses it? |\n|---|---|---|\n| Signature, event-type filter, dedup, per-user lock, ownership guard | ingress middleware + event guard (PLAN.md:12-39) | Yes (unchanged) |\n| Missing/empty user_id, unknown user | adapter + lookup-result guard (:19-20, :43-44) | Yes |\n| Handler routing | `WebhookDispatcher` (:10-11, :105-108) | **No: bypassed. Open decision D1.** |\n| User lookup by opaque TEXT id | existing lookup (:24-26); no cast/format restriction | **No: raw SQL fragment. D2.** |\n| Receipt send + idempotency + failure record | shared mail client + recipient-policy helper (:45-53, :85-91) | Yes, but exception handling left to handler. **D3.** |\n| Order summary loading | per-order fetch loop proposed (:122-123) | **N+1. D5.** |\n| Regression coverage | existing integration suite + manual staging replay (:76-80, :118-119) | **No handler tests. D4.** |\n\nRebuilding: the handler class itself is the intended rebuild. Bypassing `WebhookDispatcher` is the only place the plan rebuilds routing that already exists; the plan itself marks that open (PLAN.md:102-103).\n\n### 0C. Dream State Mapping\n```\n CURRENT STATE THIS PLAN 12-MONTH IDEAL\n library-adapter handler ---> app-owned Webhooks:: all Stripe event handlers are\n orchestrates payment; StripePaymentWebhookHandler app-owned classes registered\n ingress guards app-owned behind existing flag; guards through one dispatcher, each\n unchanged; handler body has with unit tests + fixture replay;\n raw SQL, coupled mail, N+1, no raw SQL anywhere in webhooks\n no tests\n```\nDirection: toward the ideal on ownership, away from it on routing (bypass), safety (raw SQL), and test coverage. The four decisions below turn \"toward\" into \"toward on every axis\" without widening scope.\n\n### 0E. Mode provenance\nExplicit user instruction: \"review this plan thoroughly in HOLD SCOPE mode\" \u2192 HOLD SCOPE. No question asked, no question log.\n\n### 0G. HOLD SCOPE checks\n1. Complexity: 1 new class, est. 2-4 files (handler, registration/flag wiring, tests, possibly a query helper). Under the 8-file / 2-class threshold. No challenge.\n2. Minimum changes for the goal: the handler class + flag wiring. Nothing in the plan is deferrable without blocking the goal; no defer/keep questions raised.\n3. Stated invariants to keep (PLAN.md:7-103): all retained contracts. Repairs needed to meet them (D2, D3, D5) are in scope. D4 is completeness for new code, not expansion.\n\n## Decision ledger\n\n| ID and owner | Contract and evidence | Current | Proposed | Status | Exact approval and scope |\n|---|---|---|---|---|---|\n| D1 (architecture; owner: plan author) | PLAN.md:10-11, :100-108.

No direct route around the dispatcher. The existing handler feature flag selects prior vs new handler at the dispatcher registration point. Namespace separation is achieved by the approved class name, not by a second routing path. Implementer must confirm in code where each ingress guard lives; with A this is informational, not a safety gate.\n\n## currentDecision: D2\n\n**Question:** D2 \u2014 How does the handler look up the user from `request.params.userId`?\n**Header:** SQL lookup\n\n**ELI10:** The user ID arrives from Stripe metadata as any nonempty string, including quotes, semicolons and Unicode (PLAN.md:21-26). The plan pastes that string straight into a SQL fragment (PLAN.md:110-112). A valid Stripe signature only proves Stripe sent it, not that whoever set the metadata was friendly. Anyone who can set `metadata.user_id` on a PaymentIntent (the checkout client, a compromised integration, a test-mode key) controls part of a query that runs with the app's database credentials. Every mainstream data layer already has a parameterized finder that makes this a non-issue.\n\n**Stakes if wrong:** SQL injection on the payment path: data exfiltration or destruction with app DB credentials, plus a lookup that breaks on ordinary IDs containing quotes.\n\n**Recommendation:** A because the existing lookup already treats IDs as opaque TEXT with no cast; a bound-parameter finder is the smallest change that honors that contract and closes the injection.\n\n**Completeness:** A=10/10, B=9/10\n\nA) Use the existing parameterized lookup (ORM finder or the current lookup helper) with `userId` as a bound value (recommended). Effort S (human ~1 hour / CC ~5 min). Risk low. Pros: injection impossible by construction; reuses the same lookup the prior handler used, so opaque-TEXT semantics (punctuation, Unicode, no format restriction) are preserved exactly; nothing new to maintain. Cons: if the prior lookup helper is library-adapter-owned it may need a small extraction into app code. Reuse: existing lookup helper / ORM. Verification: handler test with an injection-shaped ID (`'; DROP TABLE users;--`), a Unicode ID, a punctuation-only ID, and an unknown ID (D4).\n\nB) Keep raw SQL but pass `userId` as a bind parameter (placeholder + args). Effort S (human ~1 hour / CC ~5 min). Risk low-medium. Pros: injection closed; keeps the \"raw SQL\" shape if there is a real reason for it (none stated). Cons: a second, hand-written lookup for the same table that must stay in sync with the ORM's TEXT comparison/collation; reviewers must re-verify each edit never regresses to interpolation. Reuse: DB client only. Verification: same test set as A.\n\n(No third option: interpolating the external string is not viable under PLAN.md:21-23 and is not offered.)\n\n**Commitment table (Proposed):**\n```\nCommitment | Source/approval or pending | Current | A | B\nIDs opaque TEXT, no cast/format | existing PLAN.md:24-26 | yes | yes | yes (must match collation)\nExternal string bound, never | pending D2 | interpolated | bound via finder | bound via placeholder\n interpolated\nLookup implementation | pending D2 | new raw fragment | existing finder | new raw query w/ binds\nUnknown-user guard behavior | existing PLAN.md:43-44 | 200 + log, stop | unchanged | unchanged\nD1 | approved A | - | dispatcher | dispatcher\nD3-D5 | pending | - | pending | pending\n```\n\n**Net:** reuse the existing safe finder vs. maintain a second hand-written query that is safe only as long as nobody edits it carelessly.\n\n## NOT in scope\n(none yet)\n\n## Deferred to TODOS.md\n(none)\n", "savedSha256": "2269caae115a2b93cf4f544c4a867cd9b01b0061c21bdf6f5b8ffb9302313c37" } ] }
