2026-05-30chore(notes): collect loose root docs into notes/; add reconcile edge-cases noteAdam Malczewski
Move all loose root-level .md files (plans, reports, gemini reviews, incident notes) into a single notes/ directory, and update the doc-reference breadcrumbs in code comments/test labels to the notes/ path. Add notes/queue-interrupt-reconcile-edge-cases.md: documents why the queue/interrupt/turn-sealed reconcile path keeps surfacing edge cases (a catalog of the four review-pass bugs, the no-loss/no-duplicate invariants, the recommended membership-based reconcile refactor, and interleaving-test guidance).
2026-05-28feat(frontend): persist sidebar panel layout across browser refreshes via ↵Adam Malczewski
localStorage Carries the in-app sidebar layout (which views are open and in what order) across page reloads. Closes the natural follow-up to the tab- restore feature in d2e2e67: tabs survive, but until now the sidebar panels (Chat Settings / Tasks / Skills / Tools / etc.) reset to a single default panel on every load. Scope (explicitly bounded by the user): - Persistence target: localStorage. Matches the precedent for UI preferences (`dispatch-theme`, `dispatch-api-url`). Per-device layout; no backend round-trip. - sidebarOpen (the Header button that hides the whole sidebar column) is NOT persisted; always starts open on every load. - No drag-to-reorder UI added — persistence captures whatever order the user established via the existing add/remove buttons. Implementation: • New `packages/frontend/src/lib/sidebar-storage.ts` — pure functions `loadSidebarPanels(): string[]` and `saveSidebarPanels(selected: string[]): void`. localStorage key is `dispatch-sidebar-panels` (canonical `dispatch-` prefix). `loadSidebarPanels` is defensive against every failure mode (missing key, malformed JSON, non-array root, non-string entries, empty-after-filter, localStorage.getItem throwing under SecurityError). Returns a fresh array on every call so mutations by the caller don't pollute the module-level default constant. `saveSidebarPanels` swallows storage errors (quota / disabled / SecurityError) — best-effort. • `packages/frontend/src/lib/components/SidebarPanel.svelte`: seed the `panels: $state` from `loadSidebarPanels().map(s => ({ id: nextId++, selected: s }))` and add a `$effect` that calls `saveSidebarPanels(panels.map(p => p.selected))` whenever `panels` changes. The session-ephemeral `id` field is regenerated on every mount; only the `selected` strings round-trip. • Existing addPanel / remove / dropdown handlers untouched — they all reassign `panels` (`panels = [...panels, ...]`, `panels = panels.filter(...)`, `panels = panels.map(...)`), which triggers the new $effect. The minimum-one-panel invariant (X button hidden on idx 0) is preserved at the UI layer and reinforced by the loader's empty-fallback to the default layout. Tests: 15 new in `packages/frontend/tests/sidebar-storage.test.ts` — load with empty / valid / malformed / non-array / null / mixed-type / empty-after-filter / throwing-getItem; save round-trip; save error swallowing; overwrite semantics; empty-save / load-fallback; mutation isolation. Frontend total: 59 tests (was 44; +15). API 31, core 168 unchanged. Typecheck clean (svelte-check 0 errors), biome clean (126 files). Gemini code review (yolo mode, prompt-level write restriction to report.md only): SHIP, no findings.
2026-05-28feat: restore tab layout + in-flight chunks on browser reopen; agents keep ↵Adam Malczewski
running in background Implements the 'background-running agents + restore-layout-on-reopen' feature. Full design and parallel-implementation plan in `plan-bg-restore.md`; Gemini code review (SHIP verdict, no findings) in `report.md`. User-visible behaviors: 1. Browser-close keeps agents alive. If an agent is mid-stream when the browser closes / reloads / loses the network, it continues processing on the backend. (This was already the case in code — agents run fire-and-forget in app.ts:77-79 — but it was previously pointless because the UI never restored the tab to receive the output.) 2. Layout restore on browser reopen. Every tab that existed at the time the window was closed is restored, in original `position` order, with full persisted message history. Tabs whose agents finished while disconnected appear with the completed message. Tabs whose agents are still running appear streaming live — the in-flight assistant message is reconstructed from the backend's in-memory `currentChunks` (sent over the wire on connect) and accumulates new deltas as they arrive. 3. Explicit tab-close cancels + forgets. Clicking the X still cancels the agent (existing `stopTab` in DELETE /tabs/:id) and archives the row (`is_open = 0`), so it is not restored. No change to that path. The gap that the implementation closes: previously, App.svelte:onMount unconditionally called `createNewTab()` with a fresh UUID, ignoring every existing row in the `tabs` table. Every browser open was a clean slate. The DB had the conversation history but no way for the UI to discover it. Implementation: • New `TabStatusSnapshot` interface in packages/core/src/types/index.ts (auto-exported via existing `export * from "./types"`): interface TabStatusSnapshot { status: AgentStatus; currentChunks?: Chunk[]; // present iff running currentAssistantId?: string; // present iff running } • `agent-manager.ts:getAllStatuses()` rewritten to return `Record<string, TabStatusSnapshot>` (was `Record<string, AgentStatus>`). For running tabs only, attaches a defensive shallow copy of `tabAgent.currentChunks` (the live streaming array the per-message loop appends to) plus the DB id of the in-flight assistant message. The defensive copy is the consumer's to mutate. Idle / error tabs get `{ status }` only. `GET /status` and the WS `onOpen` snapshot both pick up the new shape automatically — neither call site changed. • Frontend mirror of `TabStatusSnapshot` in packages/frontend/src/lib/types.ts; `AgentEvent.statuses` variant updated to use `Record<string, TabStatusSnapshot>`. • New `hydrateFromBackend()` on the tab store (packages/frontend/src/lib/tabs.svelte.ts). Sequence on app mount: 1. Bail with 0 if `tabs.length > 0` (hot-reload idempotency). 2. GET /tabs → list of `is_open=1` rows in `position` order. 3. GET /status → in-flight TabStatusSnapshot map. 4. GET /tabs/:id/messages for each tab in parallel via Promise.all → persisted ChatMessage[]. 5. Build the Tab objects, splicing the snapshot's live chunks into the in-flight assistant message for every running tab (two paths: merge into the existing DB row with matching id, or append a fresh in-flight message if no row matches). 6. `tabs = restored; activeTabId = restored[0]?.id ?? null;` Every fetch is wrapped in try/catch so one tab's failure can't destroy the whole restore pass. • WS `statuses` handler in `tabs.svelte.ts:handleEvent` rewritten for the new shape. Still fires `reloadTabMessagesFromApi` on the desync case (frontend thinks running, backend says idle — the pre-existing recovery path is preserved). When backend says running, seeds in-flight chunks into the assistant message matching `snap.currentAssistantId` (creating it if needed). When backend says non-running, clears `isStreaming` on the previous in-flight message and nulls `currentAssistantId`. • `App.svelte:onMount` now awaits `tabStore.hydrateFromBackend()` before deciding whether to fall back to `createNewTab()`. Fallback condition is the doubly-defensive `restored === 0 && tabStore.tabs.length === 0`. `wsClient.connect()` fires in parallel with hydration — the resulting WS `statuses` event is per-tab idempotent against the hydrated state, so there is no race even if it arrives mid-hydration. What was NOT done (deliberately, deferred to wishlist): • Pre-existing inconsistency: core `AgentStatus` includes "waiting_for_key" but frontend `TabStatusSnapshot.status` uses only the existing 3-state pattern ("idle" | "running" | "error"). Not introduced here; mirrored the existing precedent. • Restored tabs use defaults for `reasoningEffort`, `agentSlug`, `agentScope`, `agentModels`, `workingDirectory` — these are not in the DB `tabs` schema. Future schema expansion. • Per-delta DB flushing — not needed; the in-memory snapshot covers the gap between flushAssistant calls. • LocalStorage cache of tab ids — backend DB is the source of truth. Process notes: • Implemented via parallel programmer subagents (flash agents were requested but unavailable in this environment — substituted with "programmer" agents, which share the "reads a plan, implements a single step" charter). Backend (Segment A: getAllStatuses + 5 tests) and frontend (Segment B: types + hydrateFromBackend + statuses handler + onMount + 8 tests) ran disjoint-file-ownership in parallel. • Gemini code review (yolo mode for tool access, explicit prompt-level write restriction to `report.md` only) returned a SHIP verdict with no findings against the plan. • Self-review surfaced one followup gap that Gemini's earlier plan-mode pass also caught: no explicit test for `/tabs/:id/messages` failure isolation. Added a test covering both HTTP-500 and network-error variants alongside a healthy tab, asserting per-tab failures don't destroy the whole restore. Tests: • api/tests/agent-manager.test.ts: +5 (snapshot empty record, idle-tab field omission, running-tab field inclusion, defensive copy invariant, omits chunks for running tab with null currentChunks). 31 total (was 26). • frontend/tests/chat-store.test.ts: +9 (restore-with-messages, in-flight seeding, /tabs failure → 0 returned, empty /tabs array, idempotency when tabs already exist, idle-status when /status omits, running-snapshot statuses handler seeding, idle-snapshot statuses handler clearing, per-tab failure isolation across HTTP-500 and network-error). 44 total (was 35). Totals: 243 tests across 3 packages all green; typecheck clean on core + api + frontend; biome clean across 124 files.
2026-05-28refactor(core): upgrade ai-sdk v4 → v6 + Anthropic/openai-compatible ↵Adam Malczewski
reasoning round-trip + max-thinking budget audit Migrates the LLM stack from [email protected] + @ai-sdk/[email protected] + @ai-sdk/[email protected] to [email protected] + @ai-sdk/[email protected] + @ai-sdk/[email protected]. Full design in plan-v6-upgrade.md; two rounds of Gemini code review captured in report.md. Motivation: the recurring 'reasoning-signature without reasoning' error on Claude Opus 4.7 was a v4 SDK artefact — @ai-sdk/[email protected] emitted Anthropic signature_delta as a separate stream chunk that orphaned when the model produced a signed-but-empty thinking block, and our chunk store had no signature field so the round-trip back to Anthropic was rejected on the next turn. In v6, signatures arrive inside providerMetadata on the reasoning-end event, and the orphan-signature class of bug is gone at the SDK level. Core changes: • ThinkingChunk gains optional metadata?: Record<string, unknown> (the v6 providerMetadata blob). A non-undefined metadata 'seals' the chunk: subsequent reasoning-delta opens a new chunk rather than extending the sealed one. • AgentEvent gains { type: 'reasoning-end'; metadata? } (replaces the v4 reasoning-signature variant). • toModelMessages (replaces toCoreMessages): - returns ModelMessage[] (was CoreMessage[]) - thinking → { type: 'reasoning', text, providerOptions: metadata } - tool-batch entries → { type: 'tool-call', input } (was 'args') - tool results → { output: { type: 'text', value } } ToolResultOutput • Claude OAuth uses createAnthropic({ authToken }) natively — no more custom-fetch x-api-key → Bearer swap. • rewriteBodyForOpus47 deleted — Opus 4.7 adaptive thinking is native via providerOptions.anthropic.thinking = { type: 'adaptive' }. • V1 middleware → V3 (specificationVersion: 'v3'). • v4-era normalizeMessages openai-compatible middleware deleted; the v6 openai-compatible provider extracts reasoning_content natively from { type: 'reasoning' } content parts. • applyAnthropicStructuralNormalisations (mirrors opencode provider/transform.ts:53-148): drops empty text/reasoning parts, scrubs non-[a-zA-Z0-9_-] toolCallIds, splits [tool-call, non-tool] assistant turns (Anthropic rejects tool_use followed by text). • applyOpenAICompatibleReasoningNormalisation (mirrors opencode transform.ts:217-249): lifts reasoning text into providerOptions.openaiCompatible.reasoning_content (always, even empty). Solves DeepSeek 'The reasoning_content in the thinking mode must be passed back' — the v6 SDK skips emitting reasoning_content when text is empty (dist/index.mjs:245), but DeepSeek requires the field present once thinking was used. • Tools: tool({ inputSchema: jsonSchema(zodToJsonSchema(...)) }) (was parameters: ZodSchema). AI SDK tools have no execute callback — the agent runs tools manually for permission prompts and shell-output streaming. New dep: zod-to-json-schema@^3.25.2. • fullStream event loop rewritten for v6 event shape: text-delta (text not textDelta), reasoning-start/delta/end, tool-input-*, tool-call (input not args), tool-result, tool-error (new), abort (new), start-step/finish-step, finish. Max-thinking audit (matches opencode transform.ts:642-671 budgets): • Claude enabled-thinking max budget 16000 → 31999 (Anthropic ceiling) • Claude enabled-thinking high budget 10000 → 16000 • maxOutputTokens 'budget + 8000' → fixed 32000 (matches opencode's OUTPUT_TOKEN_MAX; model self-allocates thinking vs response within) • Opus 4.7 adaptive thinking gains display: 'summarized' and sibling effort field (without these, thinking content is hidden by Anthropic and the model barely thinks). Frontend mirrors: • types.ts — ThinkingChunk.metadata?, AgentEvent reasoning-end • tabs.svelte.ts — routes reasoning-end through applyChunkEvent • ChatMessage.svelte — hides empty thinking chunks; hides the entire assistant bubble when no chunk has renderable content Gemini-review-driven fixes: • tool-error and abort stream events now surface as error chunks (were silently ignored) • toolCallId scrubbing pass (opencode transform.ts:96-122 parity) • Empty-reasoning-cull explicit test coverage for both Anthropic structural normalisation and DeepSeek path Test counts (223 tests across 3 packages, all green): • tests/chunks/append.test.ts: 44 (was 38) — reasoning-end sealing, orphan walk-back, multi-block interleaving • tests/agent/agent.test.ts: 24 (was 5) — exhaustive v6 event mappings, structural normalisations, signature/reasoning_content round-trip, tool-error/abort branches, DeepSeek scenario, empty reasoning edge case • tests/llm/provider.test.ts: 9 (was 22) — dropped 13 obsolete v4 middleware tests; new minimal tests confirm no middleware wrapping on default openai-compat path and that createAnthropic gets authToken vs apiKey correctly for OAuth vs api-key flows • tests/tools/registry.test.ts: 10 (was 4) — v6 tool() contract (inputSchema, no execute, JSON Schema for nested zod) • packages/api/tests/agent-manager.test.ts: 12 (was 7) — mock Agent emits v6 reasoning events; reasoning-end broadcast + ordering • packages/frontend/tests/chat-store.test.ts: 35 (was 32) — reasoning-end flow through Svelte $state store typecheck clean (tsc --noEmit on core + api, svelte-check on frontend), biome clean across 124 files.
