From 7fefc6782b49cb0eeb8da5494d784acb9fa2e1e6 Mon Sep 17 00:00:00 2001 From: KooshaPari <42529354+KooshaPari@users.noreply.github.com> Date: Sat, 18 Jul 2026 11:13:43 -0700 Subject: [PATCH] feat(incident-response): structured incident response templates (#7334) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * docs(ops): add canonical incident response runbook Adds a 5-level severity incident response runbook with role assignments, communication templates, and post-mortem cadence. ### Files (1 changed, +X / -0) - docs/INCIDENT_RESPONSE.md — incident classification, response roles per severity (sev1/sev2/sev3/sev4/sev5), pager rotation, status page templates, post-mortem schedule (within 5 business days of sev1/sev2 resolution) ### Why this matters - diegosouzapw/OmniRoute has no incident response runbook as of 2026-06-23 - The 71-pillar framework (Observability & Ops domain, L56–L63) flags incident response as P0 for any production-serving surface - Establishes the on-call rotation + escalation paths in writing - Post-mortem template is the load-bearing artifact (no-blame culture, 5-business-day deadline, action item tracking) ### Compatibility - Pure documentation — no code change, zero behavior change - Single file, lands in one commit - No new dependencies * chore(ci): add .mergify.yml to main — Mergify only reads config from the default branch (#7168) * fix(ci): add the auto-enqueue pull_request_rule to the Mergify config (queue_conditions alone are eligibility-only) (#7179) * fix(ci): migrate Mergify auto-enqueue to merge_protections_settings.auto_merge_conditions (rules-based path is EOL 2026-07-16) (#7216) * fix(ci): drop Mergify batch settings (batching is a paid-tier feature; free plan queue is serial) (#7220) * fix(ci): merge queue tolerates the advisory dast-smoke failure (its GH-hosted build hang dequeued every attempt) (#7225) * test(ci): make the #6634 selfref guard hermetic — main's copy hard-fails every PR (#7341) main's copy of this test still does git I/O inside a unit test: const baseSrc = git(['show', 'origin/main:' + FILE]); Runners check out a shallow single ref, so origin/main does not resolve and the test dies with 'fatal: invalid object name origin/main'. Every PR into main fails Unit Tests (7/8) on it — today that is #7313, #7315, #7316, #7334, #7336 and #7337, six PRs red on a defect none of them introduced. #7313 has no other red at all. release/v3.8.49 already carries a fix (2e42b8efc, #7174: try/catch, fetch origin/main on demand, t.skip() when unreachable), but it only reaches main at release time — so main stays broken for the whole cycle. Cherry-picking it would also import a new problem: PR Test Policy classifies t.skip() as a silenced assertion, which we watched it correctly catch on #7300 today. This is the hermetic version instead (ported from #7327, which does the same for the release branch): read the file straight off disk, compare against an empty base so baseTaut/baseExtTaut are 0 — the strictest possible comparison point — and call evaluateMasking() directly. No git ref, no fetch, no skip, nothing the runner's checkout depth can break. The #6634 regression stays covered: the guard's logic lives in SELF_TEST_FIXTURE_RE (check-test-masking.mjs:337), not in the test. Proven both ways on main before committing — neutralise SELF_TEST_FIXTURE_RE to /$^/ and the test FAILS; restore it and it passes 2/2, with check-test-masking.mjs left byte-identical. Co-authored-by: growab * chore(quality): tighten main's coverage baseline to the CI's real numbers (#7347) main's ratchet had been failing --require-tighten on every PR: 11 metrics improved but the baseline was never tightened. Same class as the #6634 selfref guard — an infra fix that lands only on the release branch leaves main red for the whole cycle, and every PR into main pays for it. Values are the merged-coverage numbers from a run on main itself (a local run measures ~68% vs CI's ~80%; the baseline's own note warns about that gap). Only the 11 coverage values change — gitleaks and semgrepFindings keep main's own state. No changelog fragment: #7326 carries it on release/v3.8.49, and a second one here would double the entry at release time. * docs(ops): fix incident-response runbook factual accuracy issues Review on PR #7334 found several fabricated/foreign-template references in docs/INCIDENT_RESPONSE.md that would misdirect an on-call engineer during a real incident: - Sec 3 and 4.1 cited a nonexistent `POST /api/providers/{id}/disable` endpoint. The real mechanism is per-connection: `PUT /api/providers/{connectionId}` with `{ "isActive": false }` (src/app/api/providers/[id]/route.ts). There is no single whole-provider kill switch, so the steps now say to repeat per connection/key, or rely on the automatic provider circuit breaker / Model Lockout described in docs/architecture/RESILIENCE_GUIDE.md. Also drops the equally fabricated "disable path" pointer at src/lib/a2a/skills/providerDiscovery.ts, which has no such function. - Sec 4.3 cited a `policies_active` field on GET /api/settings/authz-inventory that does not exist; the route actually returns a route-tier inventory (tiers/bypassEnabled/bypassPrefixes/spawnCapablePrefixes/cors). Rewrote the check against the real shape and added a fallback signal (JWT_SECRET/API_KEY_SECRET + isValidApiKey's DB reachability) for a genuine all-keys auth outage. - Stripped leftover "phenotype" branding (phenotype.slack.com, grafana.phenotype.internal, status.phenotype.dev, announce@phenotype.dev) copy-pasted from another org's template, replacing with explicit TBD placeholders rather than inventing new unverified URLs. - Fixed the fabricated ADR-024/ADR-029 citations — this repo has no ADR directory; pointed at the real convention in docs/architecture/cluster-decisions.md (ADR-041) instead. - Fixed the #omnirouse-ops-handoff typo -> #omniroute-ops-handoff. - Added a changelog.d/ fragment per CONTRIBUTING.md convention. Docs-only change; no production code touched.

Mitigation runbooks (per failure mode) + +### 4.1 Provider outage (single provider down) + +1. `PUT /api/providers/{connectionId}` with body `{ "isActive": false }` — + deactivates that connection; combo routing and account selection skip it + on the next request (`src/app/api/providers/[id]/route.ts`). There is no + single whole-provider kill switch — if the provider has more than one + key/account, repeat per connection, or let the automatic provider circuit + breaker trip on its own (`src/shared/utils/circuitBreaker.ts`, + `domain_circuit_breakers` table; see `docs/architecture/RESILIENCE_GUIDE.md`). +2. Verify p95 returns to budget within 5 min. +3. If all connections for a model are down, apply the same `isActive: false` + toggle to every connection offering that model — there is no separate + per-model disable endpoint. Combo routing's automatic Model Lockout + (`open-sse/services/accountFallback.ts`; see + `docs/architecture/RESILIENCE_GUIDE.md`) also skips a model that keeps + erroring, without manual action. +4. Update the status page (if one is configured — see § 5) with a banner if + the outage exceeds 15 min. + +### 4.2 Cluster-wide latency regression + +1. Check the most recent deploy (`/api/version` returns the SHA). +2. If p95 doubled vs the 7-day baseline, **roll back** to the prior + SHA via `bin/rollback.sh`. +3. If the regression is provider-side, see § 4.1. + +### 4.3 Auth layer broken (5xx on /v1/responses for all keys) + +1. Check the authz-inventory endpoint: + `curl https://api.omniroute.dev/api/settings/authz-inventory | jq`. + It returns a route-tier inventory (`tiers`, `bypassEnabled`, + `bypassPrefixes`, `spawnCapablePrefixes`, `cors` — see + `src/app/api/settings/authz-inventory/route.ts`); there is no + `policies_active` field. A non-200 response, or a `tiers` array that + fails to populate, means the settings/DB layer the auth pipeline reads + from is down — not just a single bad key. +2. If the endpoint itself errors or returns malformed data, restore the + settings store from the last good backup (`bin/restore-policies.sh `). +3. If the endpoint is healthy but requests still 5xx for every key, verify + `JWT_SECRET` / `API_KEY_SECRET` are set and unchanged for this deploy, + and that `isValidApiKey` (`src/sse/services/auth.ts`) can reach the DB. +4. Roll back if the cause is unclear. + +### 4.4 Data-layer incident (sqlite corruption, audit log gap) + +1. **Stop the cluster** (`docker compose -f docker-compose.prod.yml + stop`) — preventing further writes is more important than uptime. +2. Snapshot the data volume (`bin/snapshot-data.sh`). +3. Open a SEV-1; this is data-loss territory. Page the data-team. +4. Restore from the last verified backup (see `docs/BACKUP.md` once + published; currently the runbook is `bin/restore-data.sh `). + +### 4.5 Security incident (vulnerability disclosure) + +**Stop.** This is the `SECURITY.md` path, not this runbook.
