+- Status: `pending` or `reviewed`
+- Reviewer and reviewed-at timestamp
+- Keyboard: all actions reachable in logical order
+- Focus: visible, route changes deterministic, modal restore verified
+- Screen reader: headings, live regions, errors, and actions announced once

+- Color signal: every state has text/icon/structure in addition to color
+- Notes and linked defect IDs

+The blocking tuple is `(buildId, configSchemaVersion, apiContractVersion,
+assetManifestHash, releaseId)`. Versions are parsed numerically.
+
+1. additive changes preserve current required fields
+2. breaking changes require a major version bump
+3. persisted cache is discarded unless an explicit tested migration exists
+4. an incompatible config or API contract blocks product mount
+5. rollback restores HTML, assets, runtime config, API compatibility, and
+   release manifest as one coherent set

+# Performance evidence contract
+
+Performance evidence is deliberately split by measurement context:
+
+- `bundle.json` records production build output and enforces initial JavaScript
+  at 200 KiB gzip and every lazy chunk at 120 KiB gzip.
+- `lab.json` records Chromium/runner/viewport/network/CPU/cache/build context and
+  enforces LCP 2.5 s, CLS 0.10, and the named route interaction at 200 ms.
+- `field-web-vitals.json` records consent-filtered, route-ID aggregated,
+  release-specific production samples over 28 days and evaluates p75 LCP, CLS,
+  and INP against 2.5 s, 0.10, and 200 ms.
+
+The field minimum eligible-sample threshold is intentionally unresolved until
+a privacy-approved telemetry baseline exists. Therefore the field command
+fails closed with `FAIL_UNVERIFIED` when run against the example input. Provide
+`FIELD_WEB_VITALS_INPUT` and `MIN_ELIGIBLE_SAMPLES` only after that decision is
+recorded. The external input must identify a production release and an exact
+28-day export window, name the source/export, carry privacy-approval and
+threshold-decision references, and contain only non-negative route-ID samples.
+The environment threshold must be a positive integer equal to the approved
+decision embedded in the input. Invalid metadata fails as `FAIL_UNVERIFIED`;
+the example can never serve as production evidence.

+# Release, cache, and rollback contract
+
+Each deployment is an immutable `releases/<releaseId>/` artifact set. The
+provider adapter must upload assets, release manifest, runtime config, and
+verify asset reachability before atomically switching the active HTML pointer.
+The post-switch boot, route, API, telemetry, and reload-loop smoke checks close
+the deployment.
+
+Rollback selects a prior release tuple, confirms its assets and runtime/API
+compatibility, atomically switches the complete set, performs the provider
+cache action, and repeats the smoke checks. Rebuilding an old commit, replacing
+HTML alone, or declaring recovery from cache-purge completion is prohibited.
+Recovery is established by old/new reachability probes.
+
+The provider-independent cache defaults are:
+
+- hashed assets: `public, max-age=31536000, immutable`
+- HTML: `no-cache`
+- runtime config and release manifest: `no-store`
+- public source maps: disabled
+- service worker/offline cache: disabled
+
+`corepack pnpm verify:hosting-headers` uses a deterministic fixture locally.
+Set `HOSTING_BASE_URL` to probe deployed responses; production promotion
+requires the artifact to report `mode: "live"`.

+# Browser security boundary

+The browser bundle is public. Secrets, token lifecycle, raw HTML injection,
+dynamic code execution, untrusted script URLs, and public production source
+maps are prohibited defaults.
+
+`config/hosting/security-headers.json` is the declared header set. Hosting
+verification compares that declaration with live responses. CSP deliberately
+omits `unsafe-inline` and `unsafe-eval`; production code and built assets must
+remain compatible with that baseline.

+Route guards are UX hints and client validation does not replace backend

+
+- prefer a named semantic token
