C4-003 Status
status: done task: pilot_negative_matrix gate: G4 updated: 2026-08-23 America/New_York
C4-003 runs a shared negative matrix over the completed Asset Catalog, Modifier, and Mesh pilots. It covers malformed payloads, unsupported targets, stale revisions, and missing external resources; every result is normalized to a closed failure code and all three Main snapshots remain unchanged.
The Node matrix and Chromium-only pilot are deterministic and include the
focused family regressions. Evidence is under
tests/golden/corrective/C4-003/; legacy queue mutation remains forbidden.
All focused, Chromium, deterministic, regression, typecheck, governance,
protected-hash, and diff gates exited 0. Handoff manifest:
tests/golden/corrective/C4-003/manifest.json. Next corrective task:
C5-001.
