# Framework handover — Experience Architecture Freeze

| Field | Value |
| --- | --- |
| Phase / patch ID | `platform-experience-arch-freeze` |
| Area | Platform / AI Framework + Experience architecture |
| Date | 2026-07-27 |
| Kind | Documentation / architecture only — **final freeze** |
| ADR | [ADR-022](../architecture/adr/ADR-022.md) (amended) |

## Summary

Final architecture patch before frontend implementation. Added three platform contracts:

1. **Published Actions** — open Action Registry (`published-action.v1`)
2. **Public Access Model** — open access strategies (`public-access.v1`); Experience never owns auth
3. **Universal Embed Architecture** — open embed types (`universal-embed.v1`)

Experience Platform architecture is marked **ARCHITECTURE COMPLETE**. No backend, frontend, migration, or API implementation.
