Node 24+, no runtime dependencies. Uses built-in `node:sqlite`. Set `TRACE_PASSWORD`. Nothing publishes automatically: export creates a draft under `data/exports/` for manual review.
Git candidate scanning is optional and disabled by default. If an installation deliberately mounts read-only repository mirrors, list their container paths in `TRACE_REPOS`; production receipt ingestion does not require repository access.
Producer onboarding, shared-runner examples, deployment-host responsibilities, and verification are documented in [`docs/INTEGRATING_PROJECTS.md`](docs/INTEGRATING_PROJECTS.md).
`POST /api/v1/events` accepts versioned build/deployment receipts using a project-scoped bearer token configured as `TRACE_RECEIPT_TOKENS=goonk:token,retur:other-token`. Event IDs are idempotent. `GET /api/v1/public/projects/:project/latest` returns an explicit allowlisted projection; raw payloads remain private.
