The reviewer skill recorded four deterministic checks as unenforced or partial. Add tests so they fail the build instead of relying on a reviewer noticing.
tests/test_model_contract_guards.py:
- Status vocabulary: flags string literals compared against or assigned to status/purpose attributes, plus a narrower sweep that requires every status-valued literal in the package to be a known non-status use.
- Relationship loading: every Relationship must declare lazy='raise' except documented exceptions, and the exception set must match the Relationship Loading Contract in docs/schema.md.
- Schema fidelity: the Field-Accurate Table Contracts tables must match db/models.py on table coverage, field names, and declaration order, and the Authoritative Enumerations section must match the enum members.
tests/test_orphan_sweep.py:
- Locks the set of unreferenced public definitions. Route handlers registered by decorator are exempt, string entrypoint references count, and tests/ and tools/ count as consumers. KNOWN_ORPHANS records the four current orphans with rationale; a new one fails the build.
Each guard was mutation-tested: reverting the fix below, dropping a documented field, widening a lazy strategy, and adding a stranded function each fail their respective test.
Also fix the one violation the status guard found: sources_page.py compared attempt.status.value to the literal 'transcribed' instead of JobSourceStatus.TRANSCRIBED, which would survive an enum rename.
