| ID | Status | Owner(s) | Depends on | Description | Exit Criteria |
|----|--------|----------|------------|-------------|---------------|
| SP9-BLDX-09-001 | DONE | BuildX Guild | SCANNER-EMIT-10-601 (awareness) | Scaffold buildx driver, manifest, local CAS handshake; ensure plugin loads from `plugins/scanner/buildx/`. | Plugin manifest + loader tests; local CAS writes succeed; restart required to activate. |
| SP9-BLDX-09-002 | DONE | BuildX Guild | SP9-BLDX-09-001 | Emit OCI annotations + provenance metadata for Attestor handoff (image + SBOM). | OCI descriptors include DSSE/provenance placeholders; Attestor mock accepts payload. |
| SP9-BLDX-09-003 | DONE | BuildX Guild | SP9-BLDX-09-002 | CI demo pipeline: build sample image, produce SBOM, verify backend report wiring. | GitHub/CI job runs sample build within 5 s overhead; artifacts saved; documentation updated. |
| SP9-BLDX-09-004 | DONE (2025-10-19) | BuildX Guild | SP9-BLDX-09-002 | Stabilize descriptor nonce derivation so repeated builds emit deterministic placeholders. | Repeated descriptor runs with fixed inputs yield identical JSON; regression tests cover nonce determinism. |
| SP9-BLDX-09-005 | DONE (2025-10-19) | BuildX Guild | SP9-BLDX-09-004 | Integrate determinism check in GitHub/Gitea workflows and capture sample artifacts. | Determinism step runs in `.gitea/workflows/build-test-deploy.yml` and `samples/ci/buildx-demo`, producing matching descriptors + archived artifacts. |
