  "ownedBefore": "# Plan: Payment Processing Integration \u2014 CEO Review (HOLD SCOPE)\n\nReviewed plan: `PLAN.md` (commit a44b853). Mode: HOLD SCOPE (explicit user choice).\nBranch: main | Base branch: main (no remote; git-native fallback) | Date: 2026-09-15\nReview only. No code changed.\n\n## Context\n\nThe approved motivation is to move payment orchestration out of the prior\nlibrary-adapter handler into application-owned code while retaining the existing\npayment and receipt product behavior. The plan under review proposes four\nimplementation choices (dispatcher bypass, raw SQL lookup, inline unguarded email,\nno tests, per-order loop). This review holds scope and traces every failure path\nof those choices against the \"Existing contracts retained\" section of PLAN.md,\nwhich is the only evidence available: this repo contains no application code, so\nevery contract is treated as stated-but-unverified.\n\n## Pre-review system audit\n\n- Repo: one commit (`a44b853 Seed review plan`); files: `CLAUDE.md`, `PLAN.md`. No remote, no stash, no TODO/FIXME, no TODOS.md, no design doc, no CEO handoff note.\n- Retrospective: no prior review cycles or reverts on this branch.\n- Frontend/UI scope: none. Section 11 will be skipped as no-UI.\n- Prior learnings: none recorded (`LEARNINGS: 0`).\n- Landscape (WebSearch; Aside unavailable): Stripe docs and current guides agree on signature verification on the raw body, `event.id` dedup, idempotent handlers, 2xx within 10s, and keeping slow side effects (email) off the failure path. This plan already has every ingress guard; its gap is what the handler does *after* the payment commits.\n\n## Step 0\n\n### 0A. Premise Challenge\n\n1. **Right problem?** Yes. Moving orchestration into application-owned code is a sound ownership move and is already approved. The plan does not need a different framing; it needs its four implementation choices fixed.\n2. **Outcome?** User pays, `payment_status=paid` is committed exactly once, one receipt is sent per PaymentIntent, and on-call can tell a failed payment from a failed notification. The plan as written reaches the happy path only. Its \"no error handling on the email leg\" turns a notification failure into a payment-webhook failure, which is a proxy problem it creates for itself.\n3. **Do nothing?** The prior library-adapter handler keeps working behind the existing flag. The pain is ownership/maintainability, not a user-facing outage. That means there is no urgency argument for shipping shortcuts; this is a two-way door with a tested rollback, so we can afford to do it completely.\n\n### 0B. Existing Code Leverage\n\n| Sub-problem | Existing code (per PLAN.md contracts) | Plan's proposal | Verdict |\n|---|---|---|---|\n| Signature verification, event-type filter, event-ID dedup, per-user lock, ownership guard | Ingress middleware + event guard, unchanged | Runs inside them | Reuse (correct) |\n| Dispatch to handler | `WebhookDispatcher` (shared, available) | Bypass it for \"namespace separation\" | **Rebuild smell** \u2014 namespace separation already comes from the approved `Webhooks::` module name, not from the dispatch path. Pending D1. |\n| User lookup by opaque TEXT id | Existing lookup (no cast, no format restriction) | Raw SQL fragment from `request.params.userId` | **Regression** \u2014 the existing contract says every nonempty string is a valid id; raw interpolation cannot satisfy that. Pending D2. |\n| Missing/nil/empty email | Retained recipient-policy helper (`skipped_missing_address`) | Reused | Reuse (correct) |\n| Email send failure/timeout | Shared mail client rethrows `MailTimeout`/provider errors after durably recording the attempt; runbook retries the notification only | No error handling; exception reaches ingress \u2192 HTTP 500 \u2192 Stripe replays payment event | **Contradicts runbook contract.** Pending D3. |\n| Observability | Existing traces (event ID, user ID, handler identity), dashboards, alerts | Retained | Reuse (correct); one new named outcome needed if D3 A is accepted |\n| Rollout | Existing feature flag + tested rollback + manual staging replay | Reused | Reuse (correct) but manual only |\n| Regression coverage | \"Existing integration suite\" (unspecified whether it exercises the *new* handler) | No new tests | **Gap.** Pending D4. |\n| Order summary loading | Existing per-order loop semantics (data loading only) | Fetch each order in a loop | **N+1** inside a 2s DB deadline. Pending D5. |\n\nNothing here is a parallel flow that should be captured from an existing one; the handler is the right place. The only rebuild is the dispatcher bypass.\n\n### 0C. Dream State Mapping\n\n```\n  CURRENT STATE                        THIS PLAN                         12-MONTH IDEAL\n  Library-adapter handler          --> Webhooks::StripePaymentWebhook   --> All Stripe event handlers are\n  behind feature flag; guards          Handler behind same flag;            application-owned classes under\n  in ingress/event guard;              same guards; app-owned              Webhooks::, registered with one\n  shared WebhookDispatcher             namespace                            dispatcher, each with named error\n                                                                            outcomes, parameterized DB access,\n                                                                            and automated regression tests\n```\n\nThe plan moves toward the ideal on ownership. It moves *away* on two axes: a second dispatch path (if D1 keeps the bypass) and a payments codepath with zero automated tests (if D4 keeps \"none\"). Both are cheap to fix now and expensive to unwind after a second handler copies the pattern.\n\n### 0D.
