Garry TanandOpenAI Codex 9f81911136 v1.86.0.0 feat: route outside reviews by harness (#2850)
* feat: add a restricted and supervised Claude Code runner

Preserve configured authentication and models while enforcing tool access, strict completion JSON, bounded output and process cleanup. Cover argv, failure handling, session metadata and Windows process containment.

* feat: route outside reviews by harness and migrate wrapper installs

Use Claude Code from Codex and Codex from other supported hosts, with shared invocation rendering, positive gate validation and per-phase provenance. Rename /claude to /claude-code, repair managed shared and copied installations safely, and generate native Kiro skills. Add installed-workflow, failure-injection and live cross-harness regression coverage.

* test: recognize CEO mode labels without terminal spacing

The paid workflow rendered SCOPEEXPANSION at option 4, but its driver required a literal space. Match the leading mode title without cursor-spacing artifacts and ignore adjacent preview text. Preserve missing-target failures and downstream posture assertions.

* test: isolate plan-count fixtures before starting review workflows

Seed the complete test plan in a private git repository before launching Claude, so a bare slash command cannot review the live workspace while a delayed fixture message remains queued. Preserve count thresholds, parsers and budgets. Add initial-context and installed-discovery tests, and retain startup/terminal diagnostics on failed evaluations.

* test: stabilize review fixtures and Claude eval startup

Preserve source boundaries in workflow judge inputs, isolate CEO mode plans, and wait for interactive trust input readiness. Keep startup failure evidence and retain existing models, budgets, and assertions.

* test: classify collapsed review modes and isolate seeded findings

Keep review questions out of the setup count when terminal cursor positioning removes spaces. State existing webhook safeguards so the five-finding control measures its seeded defects without accidental extra security and concurrency gaps. Preserve question bands and the paired control.

* chore: prepare v1.82.0.0 release

Co-Authored-By: OpenAI Codex <noreply@openai.com>

* fix: eliminate browser and process-cleanup test flakes

Pin every CI surface to Bun 1.4.0 to avoid extra-stdio finalizers closing
reused live sockets. Add an isolated GC/listener regression that fails on
Bun 1.3.13, and prevent coordinated rollback to an affected CI runtime.

Check renderer cleanup against the render's own staging directory so
concurrent renders cannot invalidate the assertion. Make the no-pgrep
process-tree walk tolerate disappearing /proc entries, and synchronize
its test fixture through child readiness and pipe EOF instead of sleeps.

Validation: 9,157 passed, 31 skipped, zero failures across 556 files with
retries disabled. Build, all-host generation freshness, and skill checks
passed. All three races have failing-before/passing-after regressions.

* fix: count completed native review questions in evals

* fix: drive review navigation from confirmed native choices

* fix: require complete section-loading eval reports

* test: isolate telemetry HTTP transport from local assertions

* fix: keep review input on the active native question

* test: let tunnel revocation daemon choose an available port

Load installed host reviews at autoplan phase entry and wait for completed
reviewers and saved artifacts. Reuse approved remedies while preserving
individual finding decisions.

Drive interactive evals from the current terminal viewport, bind native
questions across scrolling, and require complete native report evidence.
Cover captured stale menus, permission lifecycles, setup classification,
and disabled-review tool availability with deterministic regressions.

Advance release metadata and the upgrade migration to the unclaimed
1.83.0.0 slot.

* fix: drive native review questions and preserve current plans

Use the native single-choice keyboard protocol and current terminal viewport,
with per-question navigation inside packets and completed-call coverage.
Keep permissions, multi-select menus, and Submit controls distinct.

Send Autoplan reviewers the amended implementation plan, keep its review record
separate, and supply retained application contracts in the chain fixture.
Clarify individual DevEx decisions and complete CEO fix options; use one active
plan destination for the section-loading report.

substantive decision, closed handoff, and cache-finding classification, and
honor the recommended implementation approach in native review dialogs.

Add captured-transcript regressions without changing review thresholds,
provider models, retries, or deadlines.

* test: fix Windows CI fixtures and credential scan

Rebase captured JSON values and filesystem evidence using the appropriate
path convention. Compile native fake CLIs on Windows and synchronize pipe
holder readiness, with cleanup retained when assertions fail.

Assemble synthetic credential fixtures at runtime so the added-line scan
keeps enforcing the same gate without flagging its own rejection controls.

Discover generated skills directly for the empty-find regression check,
avoiding a recursive scan through saved evaluation artifacts and dependencies.

* fix: preserve source renders on Windows

Compare canonical generator paths using native separators so an output
sidecar pointing at the source cannot overwrite its skill or metadata.
Keep the regression fixture isolated from the real checkout and expose
freshness diagnostics before asserting subprocess status.

Detach Windows drain-test pipe holders from the fake provider's automatic
child cleanup while preserving the enclosing runner job and its assertions.

* fix: clarify outside review fallback and CEO decisions

Render one applicable own-harness fallback path and retain native review,
disabled policy, and missing-coverage semantics. Align report field names
and mode labels, and make the existing per-cut scope approval explicit.

Regenerate skill outputs and keep the workflow judge's model, thresholds,
and retry policy unchanged.

* chore: move release to free version slot (v1.86.0.0)

PR #2852 now claims v1.85.0.0. Align the release metadata and
rename migration so upgrades from that version still receive it.

"report": "# CEO Plan Review: Payment Processing Integration\n\n**Generated:** 2026-09-09 \n**Branch:** main | **Mode:** HOLD SCOPE (selected after Step 0 analysis) \n**Reviewer:** /plan-ceo-review \n\n---\n\n## Context\n\nThe plan adds `StripePaymentWebhookHandler` \u2014 a new class to process `payment_intent.succeeded` Stripe webhook events. It reads user ID from the event metadata, looks up the user in the database, updates payment status, and sends a notification email. The plan retains all existing middleware: signature verification, event deduplication, per-user transaction locking.\n\n---\n\n## Step 0: Nuclear Scope Challenge\n\n### 0A. Premise Challenge\n\n**Is this the right problem to solve?** Yes \u2014 a webhook handler for payment success events is the correct response to Stripe's async payment model.\n\n**Is the plan the most direct path?** No. The plan's database access section introduces a critical SQL injection vulnerability by forwarding an unsanitized external string directly into a raw SQL fragment. The plan text explicitly acknowledges this: *\"a valid signature does not make it safe for SQL.\"* That sentence is a warning, not a justification. A Stripe signature validates that Stripe sent the event; it says nothing about what Stripe's *customer* put in the `metadata.user_id` field. Any attacker who controls a Stripe account can craft a `metadata.user_id` payload like `' OR 1=1--` and execute arbitrary SQL against the database.\n\n**What would happen if we did nothing?** Payments succeed in Stripe but users never get a status update or email confirmation. That's real pain \u2014 but shipping SQL injection to fix it is trading one crisis for a worse one.\n\n**Core premise score:** Sound goal, critically broken implementation path.\n\n### 0B. Existing Code Leverage\n\nThe plan acknowledges but **bypasses** `WebhookDispatcher` on grounds of \"namespace separation.\" That justification is architectural debt masquerading as taste. The WebhookDispatcher already handles routing, so a bypass creates two parallel code paths for webhook handling. If the dispatcher has retry logic, logging hooks, or middleware integration \u2014 none of that applies to the new handler.\n\n### 0C. Dream State (12-Month)\n\n```\nCURRENT STATE THIS PLAN 12-MONTH IDEAL\nNo webhook handler ---> Handler w/ SQL injection X Handler via WebhookDispatcher\n No tests X Full unit + integration test suite \n Inline email, no catch X Email via background queue\n N+1 order queries X Single JOIN query\n Bypasses dispatcher X Dispatcher extended, consistent path\n```\n\nThe plan moves away from the 12-month ideal on every dimension except the core feature (payment status update).\n\n### 0C-bis. Implementation Alternatives\n\n```\nAPPROACH A: Minimal Fix (patch-in-place)\n Summary: Keep the new handler class, parameterize the SQL query, add try/catch\n on the email leg, add targeted tests.\n Effort: S (human: ~4h / CC: ~15 min)\n Risk: Low\n Pros: Smallest diff. Fixes the P0 SQL injection. Unblocks shipping.\n Cons: Retains N+1 query problem. Dispatcher bypass remains. Email still inline.\n Reuses: Existing handler class structure, existing DB client parameterized query API\n\nAPPROACH B: Proper Integration (recommended)\n Summary: Route through WebhookDispatcher, use parameterized SQL, add error isolation\n on the email leg (catch + log + background retry), fix the N+1 with a JOIN,\n add handler-specific tests.\n Effort: M (human: ~1.5 days / CC: ~45 min)\n Risk: Low-Med (more code surface, but each piece is straightforward)\n Pros: Eliminates all identified defects. Consistent with existing infrastructure.\n Scales. Testable. On the right trajectory toward the 12-month ideal.\n Cons: More files touched. Requires understanding WebhookDispatcher internals.\n Reuses: WebhookDispatcher, existing parameterized query utilities, existing retry infra\n\nAPPROACH C: Queue-based Fan-out\n Summary: Payment update inline; email notification pushed to a background queue\n (Sidekiq/Celery/etc.) so the webhook handler is never blocked by email.\n Effort: L (human: ~3 days / CC: ~2h) \u2014 requires queue infrastructure\n Risk: Med (introduces new dependency if queue doesn't exist)\n Pros: Decouples payment confirmation from notification delivery. Email retries\n become first-class, independent operations with their own dashboards.\n Cons: Overkill if a queue isn't already in place. Higher setup cost.\n Reuses: Existing mail client, existing dashboard/alert infrastructure\n\nRECOMMENDATION: Approach B \u2014 correct cost, eliminates all defects, uses existing\ninfra. Approach A is the floor (minimum to unblock), not the target.\n```\n\n---\n\n## Critical Issues Identified\n\n### P0 \u2014 SQL Injection\n\n**Location:** Database access section \n**Detail:** `request.params.userId` is an external string from Stripe event metadata. The adapter explicitly does NOT sanitize it. The handler reads it \"directly into a raw SQL fragment.\" This is textbook SQL injection. The Stripe signature proves Stripe sent the event; it does not constrain what value the Stripe account holder put in `metadata.user_id`.\n\n**Impact:** Arbitrary SQL execution by any party who controls a Stripe account linked to this system.\n\n**Fix:** Use parameterized queries / prepared statements. Never interpolate external strings into SQL fragments regardless of upstream provenance.\n\n```\nBEFORE: \"SELECT * FROM users WHERE id = '#{userId}'\"\nAFTER: db.query(\"SELECT * FROM users WHERE id = $1\", [userId])\n```\n\n### P1 \u2014 Email Failure Propagation (Undefined Retry Semantics)\n\n**Location:** Webhook fan-out section \n**Detail:** Email fires inline with no error handling. The mail client rethrows exceptions. If the DB has already committed and email throws, the exception propagates upward. The dedup guard records completion only after DB commits \u2014 but the exception may interrupt execution before the dedup completion record is written (depending on execution order). Result: Stripe receives HTTP 500, retries the event, the dedup guard sees the event as incomplete, and the handler runs again. The DB update is idempotent (same values), but the email may fire again on the second attempt.\n\nThe plan's runbook handles this via \"existing notification retry procedure\" \u2014 but only if the on-call engineer is paged and intervenes. Silent email failure with Stripe retry is not a self-healing loop; it is a paging incident with a manual resolution path, not a planned error mode.\n\n**Fix:** Wrap the email call in try/catch. Log the failure. Let the dedup guard complete. Retry the email separately via existing retry procedure or background queue.\n\n```\n# BEFORE\nupdate_user(userId)\nsend_confirmation_email(userId) # throws \u2192 HTTP 500 \u2192 Stripe retry\n\n# AFTER \nupdate_user(userId)\nbegin\n send_confirmation_email(userId)\nrescue EmailDeliveryError => e\n log.error(\"email_failed\", user_id: userId, event_id: event_id, error: e)\n # dedup guard records completion; runbook/retry-queue handles email separately\nend\n```\n\n### P1 \u2014 No Tests\n\n**Location:** Tests section \n**Detail:** \"None planned. We'll rely on the existing integration suite catching regressions.\" A payment handler is the highest-risk component in the system. Relying on an existing suite that was not written to cover this handler is not a testing strategy \u2014 it's deferred liability. The plan's own \"manual rollout checklist\" acknowledges verification is needed; that verification should happen in a test suite, not on a staging payment replay.\n\n**Minimum test coverage required:**\n- Valid payment intent, known user \u2192 DB updated, email sent\n- Valid payment intent, unknown user \u2192 HTTP 200, no update, no email\n- SQL injection attempt in userId \u2192 parameterized query, no execution, no error\n- Email failure \u2192 DB committed, HTTP 200, error logged (after P1 fix above)\n- Duplicate Stripe event \u2192 dedup guard fires, no duplicate update\n\n### P2 \u2014 N+1 Query (Orders Loop)\n\n**Location:** Performance section \n**Detail:** \"hits the database for the user, then fetches each order in a loop.\" Each order is a separate query. A user with 50 orders = 51 database round-trips per webhook event.\n\n**Fix:** Replace the loop with a single JOIN or batch query: `SELECT * FROM orders WHERE user_id = $1`.\n\n### P2 \u2014 WebhookDispatcher Bypass\n\n**Location:** Architecture section \n**Detail:** \"bypasses the existing `WebhookDispatcher` module \u2014 we want a clean namespace separation.\" Namespace separation is achievable without a bypass. The bypass creates a second webhook handling code path outside the dispatcher's observability, retry, and routing logic.\n\n**Fix:** Register `StripePaymentWebhookHandler` within `WebhookDispatcher` under a payment namespace. This achieves namespace separation without infrastructure fragmentation.\n\n---\n\n## Error / Rescue Map\n\n```\nEVENT RECEIVED\n\u2502\n\u251c\u2500 Signature invalid \u2192 HTTP 401 [existing, unchanged]\n\u251c\u2500 Not payment_intent.succeeded \u2192 HTTP 200 [existing, unchanged]\n\u251c\u2500 userId missing/nil/empty \u2192 HTTP 200 + warning [existing, unchanged]\n\u2502\n\u251c\u2500 userId present (nonempty, unsanitized) \u2192 HANDLER INVOKED\n\u2502 \u2502\n\u2502 \u251c\u2500 SQL INJECTION RISK HERE (P0) \u2190 must fix before shipping\n\u2502 \u2502\n\u2502 \u251c\u2500 DB lookup fails \u2192 HTTP 500, Stripe retries [existing ingress wrapper]\n\u2502 \u251c\u2500 User not found \u2192 HTTP 200, logged [existing lookup-result guard]\n\u2502 \u2502\n\u2502 \u2514\u2500 User found \u2192 update payment_status + send email\n\u2502 \u2502\n\u2502 \u251c\u2500 DB update fails \u2192 exception \u2192 HTTP 500, Stripe retries [existing]\n\u2502 \u2502\n\u2502 \u251c\u2500 Email fails (no catch) \u2192 exception \u2192 HTTP 500\n\u2502 \u2502 \u2502\n\u2502 \u2502 \u251c\u2500 If before dedup completion record: Stripe retries entire flow\n\u2502 \u2502 \u2502 \u2192 DB update idempotent, email may fire again \u2190 P1 risk\n\u2502 \u2502 \u2514\u2500 If after dedup completion record: Stripe retries, dedup blocks\n\u2502 \u2502 \u2192 user never gets email; manual runbook required\n\u2502 \u2502\n\u2502 \u2514\u2500 All success \u2192 HTTP 200, dedup records completion [existing]\n```\n\n---\n\n## Data Flow Diagram\n\n```\nStripe POST /webhook\n \u2502\n \u25bc\n[Signature Verification] \u2190 existing, unchanged\n \u2502\n \u25bc\n[Event Type Filter] \u2014 only payment_intent.succeeded \u2190 existing\n \u2502\n \u25bc\n[Payload Adapter] \u2014 userId = event.data.object.metadata.user_id\n \u2502 (no SQL sanitization \u2014 P0 risk)\n \u25bc\n[Event Dedup Guard] \u2190 existing, unchanged\n \u2502\n \u25bc\n[Per-User Transaction Lock] \u2190 existing, unchanged\n \u2502\n \u25bc\n[StripePaymentWebhookHandler]\n \u2502\n \u251c\u2500\u2500\u25ba DB query: userId \u2192 user record \u2190 P0: raw SQL injection here\n \u2502 \u2502\n \u2502 [Lookup-Result Guard] \u2190 existing\n \u2502 \u2502\n \u251c\u2500\u2500\u25ba DB update: payment_status=paid, payment_intent_id\n \u2502\n \u2514\u2500\u2500\u25ba Email notification \u2190 P1: no error handling here\n \u2502\n \u25bc\n [Dedup Completion Record]\n```\n\n---\n\n## Mode Selected: HOLD SCOPE\n\nRationale: The plan has a P0 security defect (SQL injection) and a P1 reliability defect (email error propagation with undefined retry semantics). The scope is right; the implementation is broken. Expand when these are fixed.\n\n---\n\n## Approach Selected: Approach B (Proper Integration)\n\nParameterized SQL, WebhookDispatcher integration, email error isolation, JOIN query for orders, test coverage. Recommended over Approach A (patch-in-place) because the plan's existing architecture smell (dispatcher bypass) would persist.\n\n---\n\n## Verification Plan\n\n1. **SQL injection**: Write a test that passes a SQL-injection-pattern string as `userId`; confirm it hits the parameterized query and returns \"user not found\" (not SQL error, not data leak).\n2. **Email failure isolation**: Write a test where the mail client throws; confirm DB updates commit, HTTP 200 is returned, and the error is logged.\n3. **Dedup**: Send the same Stripe event ID twice; confirm only one DB update and one email.\n4. **N+1**: Add a user with 10 orders; run the handler and count DB queries (should be 2: lookup + single JOIN, not 11).\n5. **Unknown user**: Send an event with a valid userId that doesn't exist in DB; confirm HTTP 200 and no DB writes.\n6. **Staging replay**: Run the existing manual rollout checklist. Verify the DB trace, email delivery, and correlated outcome trace.\n\n---\n\n## NOT in Scope\n\n- Queue infrastructure (Approach C deferred \u2014 add when email volume justifies it)\n- Expanding to other Stripe event types (separate PR)\n\n---\n\n## GSTACK REVIEW REPORT\n\n| Run | Tool | Status | Findings |\n|-----|------|--------|----------|\n| 1 | /plan-ceo-review | DONE_WITH_CONCERNS | 5 issues (1 P0, 2 P1, 2 P2) |\n\n**VERDICT:** REJECT current plan. The P0 SQL injection disqualifies it from shipping as-written. Required remediation before approval: (1) parameterized SQL for userId lookup, (2) try/catch on email leg with logged failure path, (3) minimum test suite per the 5-scenario coverage list above.\n\nRecommended path: Adopt Approach B. Estimated CC time: ~45 min. Estimated human review time: ~1.5 days. No architectural risk \u2014 all changes stay within the existing middleware stack.\n\nNO UNRESOLVED DECISIONS\n",
