## Summary - introduce surface-aware compressed governance outcomes and reuse the shared truth/explanation seams for operator-first summaries - apply the compressed outcome hierarchy across baseline, evidence, review, review-pack, canonical review/evidence, and artifact-oriented operation-run surfaces - expand spec 214 fixtures and Pest coverage, and fix tenant-panel route assertions by generating explicit tenant-panel URLs in the affected Filament tests ## Validation - `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent` - focused governance compression suite from `specs/214-governance-outcome-compression/quickstart.md` passed (`68` tests, `445` assertions) - `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Filament/InventoryItemResourceTest.php tests/Feature/Filament/BackupSetUiEnforcementTest.php tests/Feature/Filament/RestoreRunUiEnforcementTest.php` passed (`18` tests, `81` assertions) Co-authored-by: Ahmed Darrazi <ahmed.darrazi@live.de> Reviewed-on: #253
