# Changelog
All notable changes to Chat Switchboard.
## [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`)
