## Enterprise Phase Discovery Record

| Input | Finding |
| --- | --- |
| Roadmap / manifest | Next unfinished Experience phase = `experience-11.5` Localization, RTL/LTR & Media |
| Prior handover | [phase-11-4.md](phase-handover/phase-11-4.md) — templates complete; no localization/media pipeline |
| Boundaries | Experience owns locale bindings + localization shells + media **refs**; binaries only via File Storage; no Core DB access |
| Existing codebase | Foundation `ExperienceLocaleProfile` (11.0) provides language/direction catalogs; themes already expose `DirectionMode` shells; StorageProvider contract exists |
| Missing vs DoD | No site↔locale bindings, no target localizations, no media-ref aggregates/APIs, capabilities still at 11.4 |

Derived capabilities: bind locale profiles (with concrete RTL/LTR) to sites; upsert multi-locale content shells for experience targets; attach media via Storage file refs only. **Not** forms, surveys, appointments, SEO/PWA — those remain Phase 11.6+.

## Objective

Deliver Localization, first-class RTL/LTR directionality beyond foundation locale profiles, and media references that store Storage refs only (no binaries in `experience_db`) on the Experience Platform.

## Scope

### In Scope

- `SiteLocaleBinding` (site ↔ locale profile, locale_code, text_direction rtl/ltr, default flag)
- `ExperienceLocalization` (target_type/target_id/locale/text_direction + title/summary/content_json shells)
- `ExperienceMediaRef` (`storage_file_ref` only; kind/alt/caption/locale; reject data-URI / binary metadata keys)
- Policies, specifications, commands, queries
- Pagination / filter / sort / search on list APIs
- Permissions `experience.locales.*` and `experience.media_refs.*`
- Events `experience.site_locale.*` / `experience.localization.*` / `experience.media_ref.*`
- Alembic `0006_phase_115_localization_media` (head); version `0.11.5.0`
- `/capabilities` flags: `site_locale_bindings`, `localizations`, `rtl_ltr`, `media_refs`, `storage_media_refs_only`

### Out of Scope

- Forms / surveys / appointment page shells — Phase 11.6
- SEO metadata / sitemap / PWA — Phase 11.7
- Owning File Storage blobs or binary columns in `experience_db`
- Form submission / booking engines

### Tests

- [x] Health / capabilities reflect phase 11.5
- [x] Site locale binding + localization upsert lifecycle
- [x] Media ref create + reject data-URI / binary metadata
- [x] Tenant isolation + no binary columns on media model
- [x] Architecture / permission / migration / docs

## Completion Criteria

- [x] Localization and media-ref APIs + isolation tests green
- [x] No form/survey/appointment engines
- [x] Docs + handover + manifests updated to `0.11.5.0`
