# Contract compatibility and rollback rules
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"`.
