# Experience handover — Architecture Freeze (Actions / Access / Embed)

| Field | Value |
| --- | --- |
| Patch ID | `experience-arch-freeze` |
| Service | `experience` (Torbat Pages) |
| Date | 2026-07-27 |
| Kind | Architecture / documentation only — **ARCHITECTURE COMPLETE** |
| Backend version | Unchanged — `0.11.10.0` |
| Backend phases | **11.0–11.10 remain complete and unmodified** |

## Summary

Final Experience architecture freeze. In addition to Published Resources / `publish_id`:

- **Published Actions** — open registry; Experience binds; owning services execute
- **Public Access Model** — open strategies; Identity/Payment/Loyalty/Communication own challenges
- **Universal Embed** — open embed types with security/sizing/theme/analytics contracts

Architecture status: **COMPLETE**. Ready for frontend implementation phases when registered — not for further architecture redesign.

## What changed (docs only)

- [published-resource-architecture.md](../architecture/published-resource-architecture.md) — §§14–18
- [ADR-022](../architecture/adr/ADR-022.md) — amended decisions 9–15
- Contracts: action registry, public access, embed
- Roadmap / README / snapshot / manifests / glossary / boundaries

## What did NOT change

- No `backend/services/experience` code
- No migrations / APIs / frontend
- No breaking contract changes (additive only)

## Inheritance for frontend / future implementation

1. Design UI against `publish_id`, open actions, access strategies, and embed types.
2. Do not implement Action/Access/Embed engines until a phase is registered.
3. Do not put auth/payment/membership logic in Experience UI beyond calling owning services.
4. Prior handover: [phase-experience-published-resource-arch.md](phase-experience-published-resource-arch.md).
