# Changelog All notable changes to Chat Switchboard. ## [0.9.3] — 2026-02-23 ### Changed - **Code blocks: button-driven collapse** — Replaced `
` wrapper with inline collapse/expand toggle button in the code toolbar. Auto-collapses at >15 lines with a fade mask; toggle available on all blocks >5 lines. User can always expand/collapse regardless of threshold. Smooth CSS transition instead of native `
` jump. - **Thinking blocks: always visible** — Thinking blocks are always rendered in the DOM regardless of the `showThinking` setting. The setting now controls whether blocks start expanded (`
`) or collapsed. User can always click to toggle. Setting label updated to "Auto-expand thinking blocks". ### Added - **Admin default model** — New `default_model` policy in Admin → Settings. Dropdown populated from enabled models. When a user has no saved selection (fresh login, cleared browser) or their saved model is no longer available, the admin default is used before falling back to first visible. Resolution chain: `localStorage → admin default → first visible`. - **Reasoning/thinking support for OpenAI-compatible providers** — Models that send `reasoning_content` in stream deltas (Grok, DeepSeek, etc.) now have thinking blocks streamed live and persisted as `` tags. Renders as collapsible thinking blocks in both streaming and history views. - **Favicon animation during generation** — Browser tab favicon pulses with cascading dot opacity animation while a completion is in progress, restoring to the static favicon when done. - **Tool calls in message history** — Tool call metadata (name, arguments, result, error status) is now persisted alongside assistant messages in the database. History view renders tool calls as collapsed `
` blocks showing "🔧 tool_name → done" with expandable input/output JSON. - **Notes tool: "View note" link** — When a notes tool (`note_create`, `note_update`, etc.) completes, a "📝 View note" button appears in both the live streaming tool indicator and the history tool call block. Clicking opens the Notes panel and navigates directly to the note. - **Notes panel: Copy button** — "Copy" button added to note read mode, copies title + content as markdown to clipboard. - **Brand hover: jitter-free crossfade** — Sidebar brand logo→collapse icon swap uses opacity crossfade instead of `display: none` toggle, eliminating layout reflow jitter on hover. ### Fixed - **Model selector shows unavailable model** — Selector restoration searched all models including user-hidden ones. Saved selection (localStorage) for a hidden model like Claude Opus would re-select it on every page load even when only Grok was visible. Resolution now filters to visible models only. - **Refresh toast shows wrong count** — "Loaded 33 models" counted all models including hidden; now shows only visible count ("Loaded 1 model"). - **Tool calls vanish after completion** — Live streaming tool indicators disappeared when `reloadActivePath()` rebuilt messages from DB. Fixed: the `getActivePath` query now includes `tool_calls` column, and `PathMessage` carries the data through to the frontend renderer. - **Tool result "undefined results" text** — Operator precedence bug in tool result summary parser caused `undefined results` to display for note_create. Fixed summary logic to properly branch on title vs count. - **Regenerate streams at wrong position** — Regen'd response appeared below the full conversation (appended at bottom) then snapped to correct position after completion. Fixed: display is now truncated to the parent message before streaming starts, so the new response streams in-place as a clean branch. Backend context was already correct (excludes old response). - **Regenerate loses tools, reasoning, and tool execution** — Regen handler was a stripped-down copy of the completion handler missing tool definitions, tool execution loop, reasoning_content forwarding, and tool_calls persistence. Model lost access to note tools on regen and fell back to generic capabilities. Refactored: extracted `streamWithToolLoop()` into `stream_loop.go` as the single canonical streaming implementation. Both `streamCompletion` (normal chat) and `Regenerate` now call the shared function — only persistence differs. Future streaming features (new event types, tool capabilities) automatically apply to all code paths. - **OpenRouter free models crash** — Free models with nil pricing caused `pq: invalid input syntax for type json` on catalog sync. Nil pricing now routes through `ToJSON()` producing `"{}"` instead of nil `[]byte`. - **API key appears unsaved** — `ListGlobalConfigs` returned raw `ProviderConfig` structs where `APIKeyEnc` is `json:"-"` (never serialized), so `has_key` was always `undefined`. Now returns computed `has_key` field. - **Case-insensitive usernames** — Login, registration, and all user lookups use `LOWER()` in SQL. All user creation paths normalize to lowercase. New migration `002_ci_username.sql` adds `LOWER()` unique indexes and normalizes existing rows. ## [0.9.2] — 2026-02-23 ### Added - **Collapsible code blocks**: Code blocks over 15 lines auto-collapse into `
` 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. - [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`)
