## Summary
- add Spec 200 for the Filament nativity and custom-surface constitution slice
- amend the shared constitution with native-by-default, fake-native, shared-family, state-layer, reviewer-guidance, and exception language
- add the full Spec 200 artifact set: spec, plan, research, data model, quickstart, tasks, contract, and requirements checklist
- align the operator UX standards doc to the new constitution vocabulary
- remove superseded `001-*` spec artifacts that were replaced by the new feature work
## Validation
- completed consistency analysis across spec, plan, tasks, and contract artifacts
- completed integrated-browser smoke check on the current TenantPilot dashboard
- no runtime tests executed because this is a docs-only governance change
## Notes
- runtime application behavior is intentionally unchanged
- enforcement automation, grep/lint guards, and regression test operationalization remain deferred to Spec 201
