+# .zizmor.yml — zizmor security audit configuration
+# https://github.com/woodruffw/zizmor
+#
+# zizmor audits GitHub Actions workflows for security anti-patterns:
+#   • Unpinned third-party actions (supply-chain risk)
+#   • Script injection via ${{ github.* }} in run: steps
+#   • pull_request_target misuse (allows untrusted code to reach secrets)
+#   • Excessive permissions / overly broad GITHUB_TOKEN scopes
+#   • Cache poisoning via actions/cache with unguarded keys
+#   • … 20+ additional audits
+#
+# MOTIVATION (2026-03 incident): the trivy-action/LiteLLM supply-chain attack
+# exploited exactly the kind of pull_request_target misconfiguration that zizmor
+# detects statically. OmniRoute's npm/Docker/Electron publish workflows are high-
+# value targets that warrant proactive audit.
+#
+# BASELINE STRATEGY: this file starts with an EMPTY ignores list. As zizmor is
+# first run against the existing workflows, findings will be reviewed:
+#   • True positives → fix the workflow (preferred)
+#   • Accepted risk  → add an entry below with a justification comment
+# This enforces the same stale-enforcement discipline as other allowlists in
+# this project: every ignore requires human sign-off and is subject to review
+# at each release cycle.
+#
+# RATCHET: zizmorFindings metric in quality-baseline.json (direction: down)
+# starts advisory; current baseline is frozen at first green run; new findings
+# must be remediated or explicitly ignored here.

+## Quality Gates & Ratchets
+
+OmniRoute has **35 CI quality gates** wired across 6 jobs in `.github/workflows/ci.yml`.
+Full inventory, per-job breakdown, and operational procedures are in
+[`docs/architecture/QUALITY_GATES.md`](docs/architecture/QUALITY_GATES.md).
+
+**Quick reference:**
+
+- Gates in job `lint` (18 checks) + `docs-sync-strict` (12 checks): pass/fail policy gates —
+  fix the violation or add an allowlist entry with a justification comment + tracking issue.
+- Gates in job `quality-gate`: ratchet — metrics (ESLint warnings, code coverage, duplication,
+  complexity) must not regress vs `quality-baseline.json`. Update via
+  `npm run quality:ratchet -- --update` when a metric genuinely improves.
+- Job `test-vitest` runs `npm run test:vitest` (MCP tools, autoCombo, cache) — blocking.
+  `test:vitest:ui` is advisory until UI component tests are triaged.
+
+**Allowlist policy (short form):** Fix the cause; use the allowlist only for pre-existing
+violations you cannot fix in the same PR. Add a comment with justification + issue number.
+Stale allowlist entries (suppressing a violation that no longer exists) will be caught by
+the stale-enforcement added in Fase 6A.3.

 10. Never bypass Husky hooks (`--no-verify`, `--no-gpg-sign`) without explicit operator approval.
 11. Never embed public upstream OAuth client_id/secret or Firebase Web keys as string literals — always go through `resolvePublicCred()` (`open-sse/utils/publicCreds.ts`). See `docs/security/PUBLIC_CREDS.md`.
 12. Never return raw `err.stack` / `err.message` in HTTP / SSE / executor responses — always route through `buildErrorBody()` or `sanitizeErrorMessage()` (`open-sse/utils/error.ts`). See `docs/security/ERROR_SANITIZATION.md`.

+# Fase 8 — Quality Gates: Supply-Chain, Contratos, Resiliência & Segurança-LLM
+
+> **Status:** PLANO APROVADO PARA DEBATE/EXECUÇÃO (owner aprovou os 4 blocos em 2026-06-13).
+> **Pré-requisito:** Fases 6A + 7 completas (branch `feat/quality-gates-phase6a-7`).
+> **Origem:** pesquisa de estado-da-arte 2026 (2 agentes, 25+ buscas web, claims verificados). Tudo OSS/self-hostable.
+
+Cada task segue o padrão consolidado: gate determinístico → métrica (catraca) ou policy (pass/fail) → wire no CI. Catracas nascem com baseline congelado do estado real. Ferramental externo entra advisory até o 1º run verde, como na Fase 7.
+
+---
+
+## BLOCO A — Supply-Chain & Artefato (o maior buraco atual; baixo esforço)
+
+### A.1 — npm/SLSA provenance
+- **Ferramenta:** `actions/attest-build-provenance` (MIT, OIDC do GitHub, zero chaves).
+- **O quê:** attestation SLSA Build L2 no publish do npm; verificável via `npm audit signatures`.
+- **Artefatos:** step no `npm-publish.yml` (`NPM_CONFIG_PROVENANCE: true` + attest). **Policy.**
+
+### A.2 — SBOM (CycloneDX)
+- **Ferramenta:** `@cyclonedx/cyclonedx-npm` + `anchore/syft` (Apache-2.0).
+- **O quê:** gerar SBOM CycloneDX por release; arquivar como artefato; alimenta o scan do Grype.
+- **Artefatos:** `scripts/build/generate-sbom.mjs`, step no release. **Artefato.**
+
+### A.3 — Container scan da imagem Docker
+- **Ferramenta:** `aquasecurity/trivy-action` (Apache-2.0).
+- **O quê:** scan da imagem publicada (CVEs/secrets/misconfig) com `--severity HIGH,CRITICAL`.
+- **Artefatos:** job no `docker-publish.yml`. **Policy** (advisory→bloqueante).
+
+### A.4 — OpenSSF Scorecard
+- **Ferramenta:** `ossf/scorecard-action` (Apache-2.0).
+- **O quê:** 20+ checks de postura (pinned-deps, token-permissions, dangerous-workflow). Casa com o zizmor da Fase 7.
+- **Artefatos:** workflow `scorecard.yml` (scheduled + push). **Catraca** (score 0–10).
+
+---
+
+## BLOCO B — Contratos & Correção (alto ROI para um proxy de formatos)
+
+### B.1 — Property-based testing (`fast-check`, MIT)
+- **O quê:** invariantes em combo-routing (round-robin não repete provider consecutivo), translators (round-trip preserva `model`), sanitizers, parser SSE. Captura edge cases que testes por-exemplo perdem.
+- **Artefatos:** devDep `fast-check`; `tests/unit/**/*.property.test.ts`. **Catraca CI** (property violada = falha). Capturar seed em CI para reprodução.
+
+### B.2 — Golden-file/contract snapshots dos translators
+- **Ferramenta:** `node:assert.snapshot` (nativo Node 22+, zero dep).
+- **O quê:** congelar output de `translateRequest`/`translateResponse` (OpenAI↔Claude↔Gemini) como JSON versionado; drift de formato dispara o gate.
+- **Artefatos:** `tests/snapshots/translator-*.json`. **Catraca CI.**
+
+### B.3 — SSE-correctness gates (lacuna sem OSS pronto → helpers custom)
+- **Building blocks:** `eventsource-parser` + `undici` (nativo).
+- **O quê:** stream fecha após `[DONE]` (sem socket pendurado); abort propaga ao upstream; nenhum listener vazado; sub-streams de combo cancelados no abort; zero dup de texto no fim (bug já documentado no CLAUDE.md).
+- **Artefatos:** `tests/integration/sse-correctness.test.ts`. **Integração.** ⭐ maior ROI do bloco (proxies de LLM sofrem socket exhaustion/leak).
+
+### B.4 (opcional) — API fuzzing + breaking-change
+- `schemathesis` (lê o `openapi.yaml`, gera centenas de casos; nightly) + `oasdiff` (breaking-change no spec, pre-commit). Ambos maduros 2026.
+
+---
+
+## BLOCO C — Resiliência Runtime (testa o coração do OmniRoute)
+
+### C.1 — Chaos/fault-injection (`Shopify/toxiproxy`, maduro)
+- **O quê:** valida circuit-breaker + connection-cooldown + model-lockout com latência/timeout/reset REAIS (não mocks). Toxics: `latency`, `timeout`, `slicer`+`reset_peer` (SSE no meio).
+- **Artefatos:** `docker-compose.test.yml` (toxiproxy), `tests/integration/resilience-chaos.test.ts`. **Nightly/integração.** ⭐ maior ROI (3 mecanismos de resiliência são o núcleo).
+
+### C.2 — Heap-growth gate (nativo, `--expose-gc`)
+- **O quê:** após N requests, `heapUsed` não cresce além de um teto (pega SSE que não fecha, listeners de combo, caches sem TTL). O projeto já teve OOM (#3069).
+- **Artefatos:** `tests/integration/heap-growth.test.ts`. **Nightly soak.** (clinic.js está descontinuado — usar nativo.)
+
+### C.3 (opcional) — Load/soak (`k6`, Grafana)
+- Thresholds p95/TTFT como gate; soak nightly de 30min detecta degradação entre releases.
+
+---
+
+## BLOCO D — Segurança LLM (emergente 2026)
+
+### D.1 — LLM eval/red-team (`promptfoo`, MIT)
+- **O quê:** `apiBaseUrl: localhost:20128/v1` → testa de ponta a ponta. (a) regressão de qualidade de saída via llm-rubric; (b) valida que os guardrails de prompt-injection (`src/lib/guardrails/`) REALMENTE bloqueiam. Presets `owasp:llm`.
+- **Artefatos:** `promptfooconfig.yaml`, job nightly. **Policy** (nightly, custo por run).
+
+### D.2 — LLM vuln-scan (`NVIDIA/garak`, ativo)
+- **O quê:** 37+ probes (jailbreak, PII-leak, system-prompt-exfil) contra o proxy. Python, job separado.
+- **Artefatos:** job nightly/release. **Nightly.**
+
+---
+
+## Descartados na pesquisa (transparência)
+`clinic.js` (heap, descontinuado 2023) → nativo. `apiaryio/dredd` (contract, arquivado nov/2024) → schemathesis/golden-files. `jazzer.js` (fuzzing coverage-guided, nicho) → fast-check cobre o ROI. Reproducible builds npm (sem tool madura; Next.js chunk IDs não-determinísticos) → SLSA provenance substitui. AI code provenance/watermarking (research-only). Tracetest (observabilidade-gate; exige OTel instrumentado primeiro) → diferir.
+
+---
+
+## Sequenciamento sugerido (a debater)
+1. **Quick wins (baixo esforço, alto retorno):** A.1 provenance, A.3 Trivy, A.4 Scorecard, B.1 fast-check, B.2 golden-files.
+2. **Estrutural:** B.3 SSE-correctness, C.1 toxiproxy, C.2 heap, A.2 SBOM.
+3. **Nightly:** D.1 promptfoo, D.2 garak, C.3 k6, B.4 schemathesis.

+title: Quality Gates Reference
+---
+
+# Quality Gates Reference
+
+This document is the authoritative reference for all CI quality gates in OmniRoute.
+It describes each gate, what it validates, which CI job it runs in, whether it uses
+a ratchet baseline or a pass/fail policy, and whether it blocks the build or is advisory.
+
+For a short summary and the allowlist policy, see the "Quality Gates & Ratchets" section
+in `CLAUDE.md`.
+
+---
+
+## Gate Inventory (35 scripts)
+
+Scripts live under `scripts/check/` (policy gates) and `scripts/quality/` (ratchet engine).
+The CI source of truth is `.github/workflows/ci.yml`.
+
+### Job: `lint`
+
+Runs on every PR to `main`. Blocks merge on failure.
+
+| Script (`npm run ...`) | Validates | Blocking |
+|---|---|---|
+| `check:node-runtime` | Node.js version is within the supported range | Yes |
+| `check:cycles` | Circular imports — all `src/` + `open-sse/` modules | Yes |
+| `check:route-validation:t06` | Zod schemas present on all routes (Tier 6 policy) | Yes |
+| `check:any-budget:t11` | `@ts-expect-error // any` count does not exceed budget (Tier 11 catraca) | Yes |
+| `check:provider-consistency` | Every provider in `providers.ts` has a matching entry in `providerRegistry.ts` (and vice-versa, within the allowlist) | Yes |
+| `check:fetch-targets` | Every `fetch("/api/...")` in client-side `src/` resolves to a real `route.ts` | Yes |
+| `check:deps` | All `npm install`-able deps across every `package.json` in the repo are in `dependency-allowlist.json`; new unpinned or slopsquatted packages flagged | Yes |
+| `check:file-size` | No source file exceeds the per-extension cap (ratchet: frozen large files in `frozen` list) | Yes |
+| `check:error-helper` | Error responses in executors/handlers use `buildErrorBody()` / `sanitizeErrorMessage()` (Hard Rule #12) | Yes |
+| `check:migration-numbering` | Migration SQL files are sequentially numbered, no gaps or duplicates | Yes |
+| `check:public-creds` | No literal OAuth `client_id`/`client_secret` or Firebase Web keys outside `publicCreds.ts` (Hard Rule #11) | Yes |
+| `check:db-rules` | No raw SQL outside `src/lib/db/` modules; no barrel-imports from `localDb.ts` (Hard Rules #2/#5) | Yes |
+| `check:known-symbols` | Provider executors, routing strategies, and translators registered in their dispatch tables match the files on disk — no orphaned or undeclared symbols | Yes |
+| `check:route-guard-membership` | Every route that spawns a child process is classified by `isLocalOnlyPath()` (Hard Rules #15/#17) | Yes |
+| `check:test-discovery` | Every `*.test.ts` / `*.spec.ts` file in the repo is collected by at least one test runner (ratchet: orphan list in `test-discovery-baseline.json` can only shrink) | Yes |
+| `check:docs-sync` | CHANGELOG version, OpenAPI version, and `llm.txt` are in sync | Yes |
+| `typecheck:core` | TypeScript compilation without errors (advisory warnings only) | Yes |
+| `typecheck:noimplicit:core` | Strict `noImplicitAny` — forward-looking; many pre-existing call sites still need annotations | **Advisory** (`continue-on-error: true`) |
+
+### Job: `quality-gate`
+
+Runs after `test-coverage`. Blocks merge on failure.
+
+| Script | Validates | Blocking |
+|---|---|---|
+| `quality:collect` | Emits `quality-metrics.json` (ESLint warning count, coverage from merged shard report) | Yes (upstream of ratchet) |
+| `quality:ratchet` | Each metric in `quality-baseline.json` has not regressed (ESLint warnings ≤ baseline; coverage ≥ baseline) | Yes |
+| `check:duplication` | Code duplication (jscpd@4) does not exceed baseline in `quality-baseline.json` | Yes |
+| `check:complexity` | File-level cyclomatic complexity does not exceed the cap | Yes |
+
+### Job: `docs-sync-strict`
+
+Runs on every PR to `main`. Blocks merge on failure.
+
+| Script | Validates | Blocking |
+|---|---|---|
+| `check:docs-all` | Meta-gate that runs the 6 sub-gates below sequentially | Yes |
+| ↳ `check:docs-sync` | CHANGELOG / OpenAPI / llm.txt version consistency | Yes |
+| ↳ `check:docs-counts` | Counts in prose (provider count, migration count, etc.) are within the ratchet window of the real counts | Yes |
+| ↳ `check:env-doc-sync` | Every env var in `.env.example` is documented in a docs table, and vice versa | Yes |
+| ↳ `check:deprecated-versions` | No deprecated version strings in docs | Yes |
+| ↳ `check:doc-links` | Internal `[text](path)` links in docs resolve to real files | Yes |
+| ↳ `check:fabricated-docs` | Routes, env vars, CLI commands, hook names, and file paths cited in docs exist in the codebase. Hard gate via `--strict`; soft-fail without flag. | Yes (via `--strict` in CI) |
+| `check:cli-i18n` | CLI command strings are present in all i18n locale files | Yes |
+| `check:openapi-coverage` | OpenAPI spec covers at least a ratcheted floor of real routes | Yes |
+| `check:openapi-security-tiers` | Security tier annotations in `openapi.yaml` are consistent with `routeGuard.ts` classifications | **Advisory** |
+| `check:openapi-routes` | Every path in `openapi.yaml` resolves to a real `route.ts` (anti-hallucination) | Yes |
+| `check:docs-symbols` | Every `/api/...` reference in `docs/**/*.md` resolves to a real `route.ts` (anti-hallucination) | Yes |
+| `i18n translation drift` | Untranslated keys in i18n locale files — warn only | **Advisory** |
+
+### Job: `i18n-ui-coverage`
+
+| Script | Validates | Blocking |
+|---|---|---|
+| `check-ui-keys-coverage` (inline) | UI i18n key coverage is ≥ 65% | Yes |
+
+### Job: `i18n`
+
+Full i18n validation matrix (one job per locale). Entire job is advisory.
+
+| Script | Validates | Blocking |
+|---|---|---|
+| `validate_translation.py quick` | Translation completeness per locale | **Advisory** (`continue-on-error: true` on whole job) |
+
+### Job: `pr-test-policy`
+
+Runs on pull requests only.
+
+| Script | Validates | Blocking |
+|---|---|---|
+| `check:pr-test-policy` | PRs that change production code in `src/`, `open-sse/`, `electron/`, or `bin/` must include or update tests (Hard Rule #8) | Yes |
+| `check:test-masking` | Changed test files do not reduce net assert count or add `assert.ok(true)` tautologies | Yes |
+
+### Job: `test-vitest`
+
+Runs after `build`. Blocks merge on failure.
+
+| Suite | Validates | Blocking |
+|---|---|---|
+| `test:vitest` | MCP server (43 tools), autoCombo, cache — vitest runner | Yes |
+| `test:vitest:ui` | UI component tests — vitest runner | **Advisory** (`continue-on-error: true`) — failing until Fase 6A UI triage |
+
+---
+
+## Ratchet Baseline (`quality-baseline.json`)
+
+The ratchet engine (`scripts/quality/check-quality-ratchet.mjs`) reads `quality-baseline.json`
+and compares it against the freshly collected `quality-metrics.json`. Any metric that regresses
+beyond its epsilon fails the build.
+
+Current tracked metrics:
+
+| Metric | Direction | Meaning |
+|---|---|---|
+| `eslintWarnings` | `down` | ESLint warning count must not grow |
+| `coverage.statements` | `up` | Statement coverage must not fall |
+| `coverage.lines` | `up` | Line coverage must not fall |
+| `coverage.functions` | `up` | Function coverage must not fall |
+| `coverage.branches` | `up` | Branch coverage must not fall |
+
+To update the baseline after a genuine improvement:
+
+```bash
+npm run quality:ratchet -- --update
+git add quality-baseline.json
+```
+
+The `--update` flag writes the current measured values into `quality-baseline.json`.
+Commit this file alongside the change that improved the metric. A PR that improves a
+metric without updating the baseline will be caught by `--require-tighten` (Fase 6A.5,
+pending implementation).
+
+---
+
+## Allowlist Policy
+
+Every gate that cannot fail on pre-existing violations uses a frozen allowlist
+(e.g., `KNOWN_STALE_DOC_REFS`, `KNOWN_MISSING`, `KNOWN_RAW_SQL`). The policy is:
+
+**Fix the root cause; use the allowlist only when the violation is pre-existing and
+cannot be fixed in the same PR.**
+
+When adding an entry to an allowlist:
+1. Include a comment with the justification.
+2. Reference the tracking issue (e.g., `// #3498 — Phase 2 feature, not yet implemented`).
+3. Remove the entry in the same PR that fixes the violation — a stale entry that no longer
+   suppresses an active violation is itself a defect (6A.3 stale-enforcement will
+   fail the gate on an orphaned allowlist entry once implemented).
+
+Do **not** add allowlist entries to make tests pass faster. A green gate with a growing
+allowlist is a false sense of quality.
+
+### When a gate fails on your PR
+
+1. **Read the gate output carefully** — it tells you exactly which file or symbol violated
+   the rule.
+2. **Fix the violation** — most gates are deterministic filesystem checks that pass as soon
+   as the code is correct.
+3. **If the violation is pre-existing** (i.e., you did not introduce it but the gate now
+   covers it): add an allowlist entry with a justification comment and a tracking issue.
+4. **If the gate is a ratchet** (coverage, ESLint warnings, duplication, complexity):
+   your change made the metric worse. Fix the underlying issue, or (rarely) run
+   `npm run quality:ratchet -- --update` if the change is intentional and the metric
+   degradation is acceptable — but document why in the PR description.
+5. **Advisory gates** (`continue-on-error: true`) are informational — they do not block
+   merge but appear in the CI summary. Fix them anyway.
+
+---
+
+## Adding a New Gate
+
+1. Create `scripts/check/check-<name>.mjs` (or `.ts`). Policy gates exit 0/1.
+   Ratchet-style gates emit a metric to `quality-metrics.json` via `collect-metrics.mjs`.
+2. Add `"check:<name>": "node scripts/check/check-<name>.mjs"` to `package.json`.
+3. Wire it in `.github/workflows/ci.yml` under the appropriate job
+   (policy → `lint` or `docs-sync-strict`; ratchet → `quality-gate`).
+4. If it has an allowlist, apply `reportStaleEntries()` from
+   `scripts/check/lib/allowlist.mjs` so stale entries are detected automatically.
+5. Write a test in `tests/unit/build/` covering the gate's detection logic.
+6. Update this document (add a row to the relevant job table).

+#   semcheck catches semantic drift: a doc that says "returns 200 on success"

+# OPERATING MODE  — ADVISORY / NON-BLOCKING
+#   - This gate is LLM-backed → runs in the NIGHTLY job only (not per-PR).
+#   - It NEVER blocks a PR merge automatically.
+#   - Findings appear as annotations in the CI summary and as a comment on the
+#     PR if triggered by a label (see ci.yml `semcheck` job).
+#   - To trigger on a specific PR: add the label `semcheck` to the PR.
+#   - To promote to blocking: set `fail-on-issues: true` and wire the job
+#     under `required-checks` in the branch protection rule.

+ *
+ * Accessibility gate using @axe-core/playwright (Task 13 — Fase 7).
+ *
+ * NIGHTLY advisory: this suite is scheduled in the NIGHTLY CI job, not in the
+ * per-PR job, because axe analysis adds ~10–20 s per page and the results are
+ * frozen baselines (see approach below).
+ *
+ * Approach — freeze-and-alert (not fail-on-first-violation):
+ *   1. Run axe on each key page.
+ *   2. Count `violations.length` per page.
+ *   3. Assert the count has NOT increased since the frozen baseline.
+ *   4. Report violations in the test output so they are visible in CI logs.
+ *
+ * This means:
+ *   - Existing violations are GRANDFATHERED (baseline frozen).
+ *   - A new violation (count grows) FAILS the gate — catraca `down`.
+ *   - Fixing a violation (count drops) passes + you can lower the baseline.
+ *
+ * Graceful degradation:
+ *   - If @axe-core/playwright is not installed the entire suite is skipped
+ *     with a clear message instead of crashing the job.
+ *   - The frozen baselines below are ADVISORY defaults (0). On the first real
+ *     run update them to the actual counts (grep "axeViolationCount" in CI logs).
+ *
+ * Pages audited (key dashboard surfaces):
+ *   /dashboard            — main overview
+ *   /dashboard/providers  — provider management (most complex UI surface)
+ *   /login                — public auth gate (a11y critical for users)
+ *   /dashboard/settings   — settings (redirects to /dashboard/settings/general)
+ *
+ * Run locally (requires the app running on localhost:20128):
