+
+## [0.9.1] — 2026-02-23
+
+### Removed
+- **Static known model table**: Deleted `knownModels` map from backend and
+  `KNOWN_MODELS` from frontend. The same model ID can have different capabilities
+  depending on the provider (e.g. DeepSeek has tool_calling on OpenRouter but
+  not on Venice). A hardcoded table can't represent this.
+- **Frontend `lookupKnownCaps()`**: Removed client-side capability guessing.
+  Backend is the sole source of truth via catalog → heuristic chain.
+
+### Changed
+- **Resolution chain simplified**: catalog (provider API sync) → heuristic inference.
+  No intermediate known table. Providers that report capabilities via API are
+  authoritative; heuristics are best-effort for unsynced models.
+- **All providers updated**: OpenAI, OpenRouter, Anthropic, Venice now call
+  `InferCapabilities()` directly instead of the dead known table lookup.
+- **Frontend `resolveCapabilities()`**: Now passes through backend caps as-is.
+  No client-side merging with a static table.
+- [x] EXTENSIONS.md recovered into repo, updated with Appendix A (Custom
+  Renderers) and Appendix B (Model Roles with utility/embedding/generation slots)
+- [x] ROADMAP.md restructured: extension foundation pulled to v0.11.0,
+  model roles to v0.10.0, dependency graph, TBD replaces post-1.0,
+  removed v0.8→v0.9 migration (OBE — no public release, no test path)
+
+### Added
+- **Heuristic patterns**: Updated to detect qwen3, gpt-5, grok, kimi, minimax,
+  glm-5, gemma-3 model families. Vision expanded to claude-opus/sonnet (not
+  just claude-3). Reasoning expanded for thinking, grok, glm patterns.
+
+### Fixed
+- **Preset capability pills**: Presets with auto-resolve (no `provider_config_id`)
+  now inherit base model capabilities via `GetByModelIDAny` catalog fallback.
+- **Venice `optimizedForCode`**: Added mapping to `CodeOptimized` capability.
+- **CI test stability**: BYOK journey tests use unreachable endpoints so auto-fetch
+  doesn't race with simulated data injection.
+
+## [0.9.0] — 2026-02-22
+
+### Added
+- **Schema consolidation**: 21 migrations collapsed to single `001_initial.sql`
+- **Store layer**: All database access through typed interfaces (no raw SQL in handlers)
+- **Persona model**: Trust-boundary model replacing old presets; scoped global/team/personal
+- **Capabilities resolver**: Three-tier chain — catalog → known table → heuristic inference
+- **Three-state model visibility**: enabled / disabled / team-only
+- **BYOK auto-fetch**: Creating a personal provider triggers model discovery from provider API
+- **User model refresh**: `POST /api-configs/:id/models/fetch` endpoint + UI button
+- **Composite model IDs**: `configId:modelId` format prevents cross-provider collisions
+- **Audit log foundation**: All admin operations logged with actor, action, resource
+- **Journey integration tests**: API-driven test suite replacing fake-data tests
+- **Frontend test suite**: 107 tests, 27 suites validating model processing pipeline
+- **Live Venice API test**: Proves real BYOK → auto-fetch → models visible flow
+
+### Fixed
+- **API key storage**: `json:"-"` tag on `ProviderConfig.APIKeyEnc` silently dropped
+  keys during admin create/update. Fixed with wrapper structs that bypass the tag.
+- **NULL model_default scan**: `scanProviders()` crashed on NULL `model_default` column,
+  silently hiding all team and BYOK models. Fixed with `sql.NullString`.
+- **Nil slice serialization**: Go nil slices serialized as JSON `null` instead of `[]`,
+  breaking frontend fallback chains. Fixed with `make([]T, 0)`.
+- **Frontend error swallowing**: API responses with `errors` field were silently ignored.
+
+### Changed
+- Backward-compatible API routes with v0.8 field name aliases
+- User model preferences table (`user_model_settings`)
