## Summary
- introduce the governance subject taxonomy registry and canonical Baseline Scope V2 normalization and persistence
- update baseline profile Filament surfaces, validation, capture/compare gating, and add the optional scope backfill command with audit logging
- add focused unit, feature, Filament, and browser smoke coverage for save-forward behavior, operation truth, authorization continuity, and invalid-scope rendering
- remove the duplicate legacy spec plan under `specs/001-governance-subject-taxonomy/plan.md`
## Verification
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Browser/Spec202GovernanceSubjectTaxonomySmokeTest.php`
- focused Spec 202 regression pack: `56 passed (300 assertions)`
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
## Notes
- no schema migration required
- no new Filament asset registration required
- branch includes the final browser smoke test coverage for the current feature
