M12-01F Status

status: done task: reject duplicate IDs, catalog cycles, oversized text, and unknown fields updated: 2026-08-17 America/New_York enablingTask: true parityStateChange: false

Scope

The negative matrix executes production schema v2 and migration parsers against duplicate catalog/asset IDs, a legacy parent cycle, an inconsistent v2 parentPath, 64-byte UTF-8 simple-name/tag values, and unknown top-level/nested fields in both v1 and v2. The byte cases use multi-byte text to prove limits are not JavaScript character counts.

Every failure returns a stable asset error code. The valid v2 fixture is parsed after each negative case to prove the failed input did not poison parser state. This task adds negative evidence only and does not change catalog parity status.

Evidence

npm --prefix web run test:asset-catalog-negatives passed 2/2 with 9/9 negative cases.
Duplicate/cycle/parent/unknown cases returned ASSET_MANIFEST_INVALID; both 64-byte UTF-8 payloads returned ASSET_BUDGET_EXCEEDED.
Typecheck, lint, and git diff --check passed.
