Changelog

All notable changes to Chat Switchboard.

[0.9.2] — 2026-02-23

Added

• Collapsible code blocks: Code blocks over 15 lines auto-collapse into <details> with language and line count summary. Language label shown in top-left corner of all code blocks.
• HTML preview: "Preview" button on HTML code blocks opens a sandboxed iframe (allow-scripts, no allow-same-origin). Auto-detected for untagged blocks via heuristic.
• Token count estimate: Live token counter below input area showing approximate tokens and context usage percentage when model has max_context.
• Context length warning: Dismissable banner above input at 75% (yellow) and 90% (red) context usage with guidance to start a new chat.
• Proxy interception detection: _parseJSON() checks Content-Type before .json() on all API paths including streaming. Typed proxyBlocked errors with proxy page title extraction and actionable splash messages.
• Environment injection: window.__ENV__ wired through entrypoint, k8s, and index.html for dev/test/production gating.
• Enhanced diagnostics: NET:PROXY log type, Content-Type capture in fetch interceptor, environment info in export header and state snapshot.
• Team admin audit scoping: New GET /api/v1/teams/:teamId/audit and /audit/actions endpoints scoped to team members. Activity Log section in team manage panel with filter dropdown and pagination.
• New favicon: Switchboard panel design with provider-colored jacks. Animated SVG (rotating plugs), 32px PNG, 256px PNG, and ICO.
• Seed users (dev/test only): SEED_USERS=user:pass:role,... env var pre-creates active users on startup. Ignored in production. K8s secret switchboard-seed-users wired in backend manifest.

[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.
• EXTENSIONS.md recovered into repo, updated with Appendix A (Custom Renderers) and Appendix B (Model Roles with utility/embedding/generation slots)
• 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)
