Status and verification rows for the six requirements landed in this
branch, plus UT-029 … UT-052, and the generated traceability matrix that
`docs/traceability.md` holds in the other two components but was missing
here. `traces-report.json` is gitignored to match the server: the matrix
is committed, the JSON report is not, since nothing reads it back.
Two corrections rather than additions:
`AudioSignatureTests` was tagged UT-029 … UT-035, IDs the register had
already assigned to the schema tests. Renumbered to UT-038 … UT-044,
matching the register, which was right — duplicate IDs defeat the point
of IDs being permanent.
`ReadCappedAsync` implements JR-028's response cap and carried no tag,
so the requirement read as uncovered.
The gate reports 0 orphan tags.
