## Summary
- add the structured subject-resolution foundation for baseline compare and baseline capture, including capability guards, subject descriptors, resolution outcomes, and operator action categories
- persist structured evidence-gap subject records and update compare/capture surfaces, landing projections, and cleanup tooling to use the new contract
- add Spec 163 artifacts and focused Pest coverage for classification, determinism, cleanup, and DB-only rendering
## Validation
- `vendor/bin/sail bin pint --dirty --format agent`
- `vendor/bin/sail artisan test --compact tests/Unit/Support/Baselines tests/Feature/Baselines tests/Feature/Filament/OperationRunEnterpriseDetailPageTest.php`
## Notes
- verified locally that a fresh post-restart baseline compare run now writes structured `baseline_compare.evidence_gaps.subjects` records instead of the legacy broad payload shape
- excluded the separate `docs/product/spec-candidates.md` worktree change from this branch commit and PR
