# Build and supply-chain gate
## Local blocking controls
- `pnpm install --frozen-lockfile` and a real manifest/lock mismatch fixture
- all direct and transitive lockfile rows with package SHA-512 integrity
- production/development, direct/transitive and platform-optional classification
- package-manifest license allow/deny policy
- approved inventory baseline digest and actual add/remove/change/upgrade diff
- independent review for new direct production dependencies
- CycloneDX 1.6 SBOM and inventory component/edge coherence
- source/lock/SBOM/dist-linked local provenance statement
- source, opt-in recipes, scripts, tests, tracked config/schema, public, built asset and generated
release metadata secret scan
- two-build `SOURCE_DATE_EPOCH` reproducibility check
The canonical commands are:
```bash
corepack pnpm verify:lockfile
corepack pnpm verify:reproducible-build
corepack pnpm build:release
corepack pnpm verify:supply-chain
corepack pnpm check:supply-chain:fixtures
```
`config/security/dependency-baseline.json` is the approved local baseline.
Changing it requires `DEPENDENCY_BASELINE_OWNER` and
`DEPENDENCY_BASELINE_REASON`; editing the digest or hardcoding an empty diff is
rejected.
## External promotion controls
The vulnerability adapter reads the file named by
`VULNERABILITY_REPORT_PATH`. It requires a provider, the exact lockfile digest,
severity findings and valid independent, unexpired exception evidence.
`PROVENANCE_ATTESTATION_PATH` must name a provider, signer and the exact built
dist subject digest.
If either provider input is absent, local verification remains meaningful but
`artifacts/security/supply-chain-verification.json` records
`promotionStatus: FAIL_UNVERIFIED`. `verify:supply-chain:promotion` then exits
non-zero. Scanner or signing outages are not converted to an empty PASS.
Approved vulnerability exceptions require vulnerability/package identity,
owner, a different reviewer, reason and expiry. Expired or self-approved
exceptions are blocking.
