# C3-002 Status status: done task: asset_catalog_positive_command gate: G3 updated: 2026-08-23 America/New_York C3-002 adds `assetCatalogAppend`, a typed positive catalog command registered for the `ASSET_LIBRARY` target. It resolves and hash-verifies the active resource before using the C2 atomic Main transaction to append one entry. Duplicate IDs, malformed payloads, resource hash failure, and stale revisions remain non-mutating. The focused command test passed 3/3 assertions. Desktop and WASM produced the same normalized positive receipt and catalog snapshot. Deterministic receipt, protected legacy hashes, typecheck, context/corrective governance, task-context, and `git diff --check` all exited 0. Evidence and manifest: `tests/golden/corrective/C3-002/`. Next corrective task: `C3-003`.
