chore: snapshot working tree - pty_exited notifications + in-flight inference WIP

feat(booterm): structured pty_exited WS notifications. Plan-validated, impl-validated, code-reviewed green (contracts build clean, contracts test 29/29, booterm + web typecheck clean).

wip: in-progress inference/provider refactor (agents.ts, provider.ts, new llama-providers.ts, removed llama-args-validator), plus arena, dispatcher, compaction, schema changes.

openspec: pty-exit-notifications complete; x-agent-flags planned (not yet implemented).

+# Self-healing log
+
+Verified fixes for runtime failures. Each entry documents a failure, its root cause, the applied fix, and the verification proof.
+
+**Pattern-Key discipline:** before filing a new HEAL, search this file for an existing Pattern-Key. If found, increment `Recurrence-Count` and update `Last-Seen` — do not duplicate.
+
+**Lifecycle:** verified heals at Recurrence-Count ≥ 3 across distinct tasks get a `Handoff` block for promotion to project memory (`CLAUDE.md`, `AGENTS.md`, or a skill).

+
+**Logged**: ISO-8601 timestamp
+**Status**: pending-verify
+**Trigger**: tool-failure | missing-capability | env-issue | external-change | <free-form>
+**Area**: free-form tag (e.g. `build`, `tests`, `ci`, `auth`, `data-pipeline`)
+**Priority**: low | medium | high | critical
+
+### Failure
+Concrete error: command, error message, exit code, blocked action.
+
+### Diagnosis
+Root cause as understood after investigation. What was verified during diagnosis.
+
+### Fix
+Patch applied. Verbatim commands, code snippets, or pointers to `.learnings/heals/<HEAL-ID>/`.

+## Active Batches — All Uncommitted, All Unshipped
+
+All 22 active batches (changes/*/) have **zero** git tags or commits referencing them. Every batch was created locally on 2026-06-07 and exists only on the filesystem.
+
+## High-Value Prioritization (for Implementation Plan)
+
+### Tier 1: Ship in Current Batch (small scope, high value)
+1. **openspec-cleanup** — Fix folder structure: delete stubs, move misplaced proposals, add .openspec.yaml, populate config.yaml
+2. **llama-cache-and-spec** — KV cache quantization + ngram speculative decoding (llama-server arg changes only)
+3. **results-page** — New `/results` route, uses existing API endpoints
+4. **token-analyzer-ui** — New `/analytics` route, uses existing DB data
+
+### Tier 2: Current+ Batch (moderate scope)
+5. **enhanced-file-panel** — Side-by-side diff, inline comments, in-browser editing
+6. **pty-enhancements** — Exit notifications, session metadata, X-Agent-Flags
+
+### Tier 3: Next Batch (larger scope, foundation work)
+7. **memory-v2-hybrid-search** — BM25 + local embedding hybrid search
+8. **orchestrator-flow-advanced** — Trigger rules, conditional branching, HITL
+9. **omo-paseo-bridge** — OMO subagent visibility in Paseo
+
+### Tier 4: Future Batches (speculative / big effort)
+10. **add-behavioral-engine** / **audit-harness-integration** / **import-llm-evaluator** / **import-pregel-engine** — Big integration efforts
+11. **code-intelligence-upgrade** / **dev-workflow** / **conductor-evolution** — Platform work
+12. **plugin-platform** / **ui-overhaul** / **add-3tier-memory** / **add-type-inject-mcp** — Future
+
+## Scope Boundaries for This Plan
+
+**IN SCOPE:**
+- Delete 11 stub files from archived/
+- Move 5 misplaced 2026-06-07 proposals from archived/ to changes/ (with dedup)
+- Add missing .openspec.yaml to 6 active batches
+- Populate openspec/config.yaml with project context
+- Implement Tier 1-2 high-value batches:
+  - llama-cache-and-spec (llama-server args)
+  - results-page (new route, frontend)
+  - token-analyzer-ui (new route, frontend + backend)
+  - enhanced-file-panel (frontend changes)
+  - pty-enhancements (backend changes)
+
+**OUT OF SCOPE:**
+- Tier 3-4 batches (future planning)
+- Full behavioral engine or Pregel state machine integration
+- Plugin platform architecture

+## Architecture
+
+```
+User writes workflow JS file:
+.boocode/workflows/my-flow.js
+
+Workflow Runtime (apps/server)
+  ├── isolated-vm sandbox (or node:vm)
+  ├── API surface: agent(), parallel(), pipeline(), phase(), budget()
+  ├── Tool bridge → BooCode's existing tool set
+  ├── Workflow manager (concurrency, lifecycle)
+  ├── Resumability cache (SHA-256 of agent spec)
+  └── Catalog (built-in workflows: deep-research, review-code)
+
+Workflow execution:
+  1. User triggers workflow (slash command or Orchestrator panel)
+  2. File discovery finds .boocode/workflows/<name>.js
+  3. Sandbox compiles and executes the script
+  4. agent() calls go through tool bridge → existing inference pipeline
+  5. parallel() spawns concurrent agent calls (max 3 default)
+  6. Results stream via existing WS frames
+  7. Completed agents cached by hash for resume
+
+API Surface (Claude Code compatible):
+  agent(prompt, { label?, schema?, model?, capabilities?, max_tool_calls? })
+  parallel([() => agent(...), () => agent(...)])
+  pipeline(items, ...stages)
+  phase(title)
+  log(message)
+  budget.total / budget.spent() / budget.remaining()
+  args
+  workflow(name, args?)  — one level of nesting
+```
+
+## Implementation Plan
+
+### Phase 1: Core Runtime (this session)
+- Sandbox using Node's `vm` module (no extra deps)
+- `agent()` function that creates a task and waits for completion
+- Workflow file discovery
+- Basic workflow manager
+
+### Phase 2: Advanced Primitives
+- `parallel()` with concurrency limits
+- `pipeline()` streaming
+- `budget()` token tracking
+- Workflow resumability cache
+
+### Phase 3: UI + Polish
+- Integration with Orchestrator panel
+- Built-in workflow catalog
+- Workflow editor
+- Error recovery

+# Enhanced File Panel — Implementation Plan
+
+## TL;DR
+
+> **Quick Summary**: Add side-by-side diff, hide whitespace, wrap lines, expand all files, inline diff comments, and in-browser file editing to BooCode's right-rail file panel.
+>
+> **Deliverables**:
+> - Enhanced `GitDiffView.tsx` with toolbar (layout/whitespace/wrap/expand-all toggles)
+> - Split-layout diff renderer (side-by-side)
+> - `useDiffPreferences` hook (localStorage persistence)
+> - Inline diff comment components + Zustand store
+> - File editing mode in file tree + server write endpoint
+> - Server `git diff -w` support
+>
+> **Estimated Effort**: Medium-Large
+> **Parallel Execution**: YES — 4 waves
+> **Critical Path**: Wave 1 (server) → Wave 2 (diff preferences + toolbar) → Wave 3 (split layout) → Wave 4 (comments + editing)

+
+## Context
+
+### Original Request
+User wants to implement these features from Paseo into BooCode's file manager:
+1. Unified diff ✅ (exists) / Side by side diff ❌
+2. Hide whitespace ❌
+3. Wrap long lines ❌
+4. Expand all files ❌ (only per-file)
+5. Refresh ✅ (exists)
+6. Comments on specific diffs ❌
+7. File edits (editing in the file browser) ❌
+
+### Research Findings
+- **Paseo** (`/opt/forks/paseo`): Best reference for all features. Key files: `diff-pane.tsx`, `diff-layout.ts`, `diff-rendering.ts`, `review/surface.tsx`, `review/store.ts`, `use-changes-preferences/`
+- **Existing BooCode files**: `GitDiffView.tsx`, `RightRail.tsx`, `useGitDiff.ts`, `git_diff.ts`, `FileViewerOverlay.tsx`
+- Key insight: None of the web references have true inline file editing in the browser — this is new ground
+
+---
+
+## Work Objectives
+
+### Core Objective
+Augment the existing file panel with side-by-side diff, whitespace/wrap/expand toggles, inline comments, and inline file editing.
+
+### Definition of Done
+- [x] `pnpm -C apps/web build` succeeds with no errors
+- [x] `pnpm -C apps/server build` succeeds with no errors
+- [ ] Side-by-side diff renders correctly (two aligned columns)
+- [ ] Hide whitespace toggles and re-fetches diff
+- [ ] Wrap lines toggles between pre / pre-wrap
+- [ ] Expand/Collapse all toggles all file diffs
+- [ ] Inline comments: click gutter → type → save → display thread
+- [ ] File edit: double-click tree → edit → save → file changes on disk
+- [ ] All preferences persist across page refresh
+
+### Must Have
+- Side-by-side diff view
+- Hide whitespace toggle (server param)
+- Wrap long lines toggle (CSS)
+- Expand/Collapse all file diffs
+- Inline diff comments with thread UI
+- In-browser file editing with save
+- Preference persistence
+
+### Must NOT Have (Guardrails)
+- No DB migration (comments are client-side)
+- No new WS frames (reuse git_diff_refresh)
+- No new `@boocode/contracts` types
+- No multi-user comment sharing
+- No git push/pull/PR operations
+- No inline hunk staging
+
+---
+
+## Verification Strategy
+
+### Test Decision
+- **Infrastructure exists**: YES (vitest for server)
+- **Automated tests**: Tests-after for new server route + `git_diff.ts` changes
+- **Agent-Executed QA**: Playwright for diff interactions, curl for API endpoints
+
+### QA Policy
+Every task includes agent-executed scenarios. Evidence saved to `.omo/evidence/`.
+
+---
+
+## Execution Strategy
+
+### Waves
+
+```
+Wave 1 (Server — foundation):
+├── Task 1: Server: whitespace param in git_diff.ts
+├── Task 2: Server: POST /api/projects/:id/write_file endpoint
+├── Task 3: Server tests for whitespace + write
+└── [tests + typecheck]
+
+Wave 2 (Frontend — preferences + toolbar):
+├── Task 4: useDiffPreferences hook (localStorage)
+├── Task 5: GitDiffView toolbar (layout/whitespace/wrap/expand-all toggles)
+├── Task 6: Wrap lines CSS + hide whitespace re-fetch
+└── [pnpm build]
+
+Wave 3 (Frontend — split layout):
+├── Task 7: Diff layout utilities (buildSplitDiffRows etc.)
+├── Task 8: Side-by-side renderer in GitDiffView
+├── Task 9: Line number gutter + alignment
+└── [pnpm build]

+├── Task 13: File editing mode in RightRail file tree
+└── [pnpm build + full smoke test]

+
+## TODOs
+
+- [x] 1. **Server: Add `ignoreWhitespace` param to git diff**
+
+  **What to do**:
+  - In `apps/server/src/services/git_diff.ts`, add `ignoreWhitespace?: boolean` to the `getGitDiff` function signature
+  - When `ignoreWhitespace` is true, append `'-w'` to the git diff argv call in `getGitDiff` (the main diff command, not name-status)
+  - Update `GET /api/projects/:id/git/diff` route in `routes/projects.ts` to accept optional query param `whitespace=1`
+  - The param should be optional (backward compatible) — default false
+
+  **Files to modify**:
+  - `apps/server/src/services/git_diff.ts` — update `getGitDiff()` to accept and use `ignoreWhitespace`
+  - `apps/server/src/routes/projects.ts` — add `whitespace` query param
+
+  **References**:
+  - Paseo: `useCheckoutDiffQuery({ ignoreWhitespace })` passes to server → `git diff -w`
+  - Existing `git_diff.ts:36-48` `runGit` function — argv pattern to follow
+
+  **QA Scenarios**:
+  ```
+  Scenario: Diff with whitespace changes respects ignoreWhitespace param
+    Tool: Bash (curl)
+    Preconditions: A file exists with whitespace-only changes (extra spaces)
+    Steps:
+      1. GET /api/projects/:id/git/diff ⇒ verify diff_body includes whitespace changes
+      2. GET /api/projects/:id/git/diff?whitespace=1 ⇒ verify diff_body excludes whitespace-only changes
+    Expected: With whitespace=1, files that only had whitespace changes show as unchanged
+    Evidence: .omo/evidence/task-1-whitespace.txt
+  ```
+
+- [x] 2. **Server: Add POST /api/projects/:id/write_file endpoint**
+
+  **What to do**:
+  - Add `POST /api/projects/:id/write_file` route in `routes/projects.ts`
+  - Accept `{ path: string, content: string }` body
+  - Validate path via existing `pathGuard` helper (same as git discard)
+  - Write file content atomically: write to `.tmp` then `rename` the file
+  - Return `{ ok: boolean }` on success
+  - Reuse the safe file-write pattern from `services/file_ops.ts`
+
+  **Files to modify**:
+  - `apps/server/src/routes/projects.ts` — add POST route
+  - `apps/web/src/api/client.ts` — add `writeFile` method
+  - `apps/web/src/api/types.ts` — add write types if needed
+
+  **References**:
+  - `apps/server/src/services/file_ops.ts` — existing file operations pattern
+  - `apps/server/src/routes/projects.ts:544-592` — git write routes (same security pattern)
+  - `apps/server/src/services/path_guard.ts` — path validation
+
+  **QA Scenarios**:
+  ```
+  Scenario: Write file content and verify on disk
+    Tool: Bash (curl)
+    Preconditions: A project exists with a writable path
+    Steps:
+      1. POST /api/projects/:id/write_file { path: "test.txt", content: "hello" }
+      2. GET /api/projects/:id/view_file?path=test.txt
+    Expected: Status 200, view_file returns "hello"
+    Evidence: .omo/evidence/task-2-write.txt
+  ```
+
+- [x] 3. **Frontend: useDiffPreferences hook**
+
+  **What to do**:
+  - Create `apps/web/src/hooks/useDiffPreferences.ts`
+  - Define `DiffPreferences` interface: `{ layout: 'unified'|'split', wrapLines: boolean, hideWhitespace: boolean }`
+  - Default: `{ layout: 'unified', wrapLines: false, hideWhitespace: false }`
+  - Read/write to localStorage key `boocode.diff.preferences`
+  - Return `{ preferences, updatePreferences, resetPreferences }`
+  - Zod-validate on read for forward compatibility
+
+  **Files to create/modify**:
+  - Create `apps/web/src/hooks/useDiffPreferences.ts`
+
+  **References**:
+  - `/opt/forks/paseo/packages/app/src/hooks/use-changes-preferences/storage.ts` — exact pattern
+  - `apps/web/src/hooks/useProjectGit.ts` — hooks pattern in BooCode
+
+  **QA Scenarios**:
+  ```
+  Scenario: Preferences persist across page refresh
+    Tool: Playwright
+    Preconditions: Page loaded
+    Steps:
+      1. Call updatePreferences({ layout: 'split' })
+      2. Read localStorage.getItem('boocode.diff.preferences')
+      3. Reload page, read preferences again
+    Expected: layout is 'split' after reload
+    Evidence: .omo/evidence/task-3-prefs.txt
+  ```
+
+- [x] 4. **Frontend: GitDiffView toolbar with all toggles**
+
+  **What to do**:
+  - Add a toolbar row inside `GitDiffView.tsx` between the mode selector and file list
+  - Controls (left to right):
+    - **Layout toggle**: two-segment button (Unified | Split) — uses `AlignJustify` / `Columns2` icons
+    - **Hide whitespace**: toggle button — `Pilcrow` icon, active state highlights
+    - **Wrap lines**: toggle button — `WrapText` icon  
+    - **Expand/Collapse all**: toggle button — `ListChevronsUpDown` / `ListChevronsDownUp` icons
+    - **Refresh**: existing button (already present)
+  - Wire each toggle to the `useDiffPreferences` hook
+  - Expand all state: compute `allExpanded = files.every(f => expandedPaths.has(f.path))`
+  - Pass expand state as a new prop or local state
+
+  **Files to modify**:
+  - `apps/web/src/components/GitDiffView.tsx` — add toolbar section, expand-all logic
+
+  **References**:
+  - Paseo `diff-pane.tsx:1114-1273` — `DiffLayoutToggleGroup`, `DiffWhitespaceToggle`, `DiffFilesToolbar`
+  - openchamber `DiffViewToggle.tsx` — simple toggle pattern
+  - happy `InlineFileDiff.tsx:196-219` — `DiffStyleToggle` segment control
+
+  **QA Scenarios**:
+  ```
+  Scenario: All toolbar controls render and toggle
+    Tool: Playwright
+    Preconditions: Git tab active with changed files
+    Steps:
+      1. Verify layout toggle shows "Unified" / "Split" buttons
+      2. Click "Split" — verify visual change
+      3. Click "Wrap" — verify wrap toggle
+      4. Click "Expand all" — verify all files expand
+      5. Click "Collapse all" — verify all files collapse
+    Expected: Each toggle works and updates state
+    Evidence: .omo/evidence/task-4-toolbar.png
+  ```
+
+- [x] 5. **Frontend: Diff layout utilities + side-by-side renderer**
+
+  **What to do**:
+  - Create `apps/web/src/utils/diff-layout.ts` with pure functions:
+    - `buildNumberedDiffHunks(diffBody: string): NumberedDiffHunk[]` — parse diff text into hunks with old/new line numbers
+    - `buildUnifiedDiffLines(file): UnifiedDiffDisplayLine[]` — existing behavior
+    - `buildSplitDiffRows(file): SplitDiffRow[]` — pair removals/additions into left/right rows
+  - Create `apps/web/src/components/DiffSplitView.tsx` — the side-by-side renderer:
+    - Two columns (left = deletions, right = additions) with a thin divider
+    - Each column has its own gutter (line numbers) + code content
+    - Use Shiki `codeToHtml(language)` for syntax highlighting per side
+    - Handle empty cells (unpaired lines render as blank)
+  - In `GitDiffView.tsx`, when `layout === 'split'`, render `DiffSplitView` instead of the unified diff body
+
+  **Files to create/modify**:
+  - Create `apps/web/src/utils/diff-layout.ts`
+  - Create `apps/web/src/components/DiffSplitView.tsx`
+  - Modify `apps/web/src/components/GitDiffView.tsx` — add layout branching
+
+  **References**:
+  - `/opt/forks/paseo/packages/app/src/utils/diff-layout.ts` — full algorithm
+  - `/opt/forks/paseo/packages/app/src/git/diff-pane.tsx:968-989` — split layout rendering
+  - existing `git_diff.ts` `splitDiffByFile` — already splits unified diff per file
+
+  **QA Scenarios**:
+  ```
+  Scenario: Side-by-side diff renders correctly
+    Tool: Playwright
+    Preconditions: Git tab active, files with changes
+    Steps:
+      1. Click "Split" layout toggle
+      2. Verify two columns appear with a divider
+      3. Verify deleted lines are on left side (red background)
+      4. Verify added lines are on right side (green background)
+      5. Verify context lines appear on both sides, aligned
+    Expected: Layout matches Paseo's split diff
+    Evidence: .omo/evidence/task-5-splitdiff.png
+  ```
+
+- [x] 6. **Frontend: Inline comment store + Zustand**
+
+  **What to do**:
+  - Create `apps/web/src/stores/useDiffCommentStore.ts`
+  - Define `DiffComment` interface: `{ id, filePath, side, lineNumber, body, createdAt, updatedAt }`
+  - Create Zustand store with:
+    - `commentsByKey: Map<string, DiffComment[]>` keyed by `${sessionId}:${mode}:${filePath}`
+    - `addComment(key, comment)` / `updateComment(key, id, body)` / `deleteComment(key, id)`
+    - `loadComments(key)` — load from localStorage
+    - `persist()` — subscribe to store changes, write to localStorage key `boocode.diff.comments.[key]`
+  - Export `useDiffCommentStore`
+
+  **Files to create**:
+  - Create `apps/web/src/stores/useDiffCommentStore.ts`
+
+  **References**:
+  - `/opt/forks/paseo/packages/app/src/review/store.ts` — zustand store for comments
+  - `/opt/forks/paseo/packages/app/src/review/state.ts` — CRUD operations
+
+  **QA Scenarios**:
+  ```
+  Scenario: Comments persist across page refresh
+    Tool: Playwright
+    Preconditions: Diff panel open with changes
+    Steps:
+      1. Add comment on a diff line
+      2. Verify comment thread appears
+      3. Reload page
+      4. Navigate to same diff
+    Expected: Comment thread still visible after reload
+    Evidence: .omo/evidence/task-6-comment-store.txt
+  ```
+
+- [x] 7. **Frontend: InlineReviewGutterCell + InlineReviewEditor**
+
+  **What to do**:
+  - Create `apps/web/src/components/InlineReviewGutterCell.tsx`:
+    - Replaces the plain line-number display in diff rows
+    - Shows line number + "+" icon on hover (to start a comment)
+    - Uses `ReviewableDiffTarget { filePath, side, lineNumber }` for tracking
+  - Create `apps/web/src/components/InlineReviewEditor.tsx`:
+    - Textarea with placeholder "Add comment..."
+    - Save (Ctrl+Enter) / Cancel (Escape) buttons
+    - Animates in below the target line
+  - Integrate into `GitDiffView.tsx` — gutter cells render in the diff line view
+  - Wire to `useDiffCommentStore`
+
+  **Files to create/modify**:
+  - Create `apps/web/src/components/InlineReviewGutterCell.tsx`
+  - Create `apps/web/src/components/InlineReviewEditor.tsx`
+  - Modify `apps/web/src/components/GitDiffView.tsx` — integrate gutter cells
+
+  **References**:
+  - Paseo `review/surface.tsx:245-309` — `DiffGutterCell` + `InlineReviewGutterCell`
+  - Paseo `InlineReviewEditor` pattern
+
+  **QA Scenarios**:
+  ```
+  Scenario: Create inline comment on diff line
+    Tool: Playwright
+    Preconditions: Git tab, file expanded
+    Steps:
+      1. Hover over a gutter cell
+      2. Click "+" button
+      3. Type comment text
+      4. Click Save (or Ctrl+Enter)
+    Expected: Comment thread appears below the line
+    Evidence: .omo/evidence/task-7-comment-create.png
+  ```
+
+- [x] 8. **Frontend: InlineReviewThread component**
+
+  **What to do**:
+  - Create `apps/web/src/components/InlineReviewThread.tsx`:
+    - Renders below a diff line when comments exist for that target
+    - Each comment shown as a card: avatar placeholder, body, timestamp, edit/delete actions
+    - Collapsed state shows comment count badge
+    - Expanded state shows full thread
+  - Integrate into `GitDiffView.tsx` below diff line rows
+
+  **Files to create/modify**:
+  - Create `apps/web/src/components/InlineReviewThread.tsx`
+  - Modify `apps/web/src/components/GitDiffView.tsx` — render thread below lines
+
+  **Reference**:
+  - Paseo `review/surface.tsx:537-573` — `InlineReviewThreadContent`
+
+  **QA Scenarios**:
+  ```
+  Scenario: Comment thread displays and supports edit/delete
+    Tool: Playwright
+    Preconditions: Comments exist on a diff line
+    Steps:
+      1. Expand comment thread
+      2. Verify comment body is visible with timestamp
+      3. Click edit → modify text → save
+      4. Click delete → verify comment removed
+    Expected: Full CRUD works on comments
+    Evidence: .omo/evidence/task-8-thread.png
+  ```
+
+- [x] 9. **Frontend: File editing in the file tree**
+
+  **What to do**:
+  - In `RightRail.tsx`, add a file edit mode:
+    - Double-click a file in the tree (or context menu "Edit") enters edit mode
+    - The file row transforms: file name becomes a monospace textarea pre-filled with file content (fetched via existing `api.projects.viewFile`)
+    - The row shows Save / Cancel buttons
+    - Save: calls `api.projects.writeFile(projectId, path, content)` — the new endpoint from Task 2
+    - Cancel: reverts to the original content and exits edit mode
+    - After save: re-fetch the file tree + emit `git_diff_refresh`
+  - Only one file editable at a time (close any existing editor before opening new)
+  - Visual indicator (highlighted row) when in edit mode
+
+  **Files to modify**:
+  - `apps/web/src/components/RightRail.tsx` — add edit mode state, edit UI
+  - `apps/web/src/api/client.ts` — add `writeFile` method (from Task 2)
+  - `apps/web/src/components/TreeLevel.tsx` (inline in RightRail) — accept edit mode props
+
+  **References**:
+  - Existing `RightRail.tsx:170-175` `openFile` function — pattern for file interaction
+  - Existing `FileViewerOverlay.tsx` — Shiki highlighting reference
+  - Paseo `file-explorer-pane.tsx` — context menu actions pattern
+
+  **QA Scenarios**:
+  ```
+  Scenario: Edit file in file tree and save
+    Tool: Playwright
+    Preconditions: Project with a text file
+    Steps:
+      1. Double-click a file in the file tree
+      2. Verify file enters edit mode (textarea replaces filename)
+      3. Modify content
+      4. Ctrl+Enter to save
+      5. Verify success indicator
+    Expected: File content updated on disk, tree refreshes
+    Evidence: .omo/evidence/task-9-edit-save.png
+
+  Scenario: Cancel file edit reverts changes
+    Tool: Playwright
+    Preconditions: File in edit mode
+    Steps:
+      1. Modify content in textarea
+      2. Click Cancel / press Escape
+      3. Re-open file
+    Expected: Original content preserved, edit mode exited

+# Paseo-like Orchestrator — Implementation Plan
+
+> **Goal:** Transform BooCode into a Paseo-style thin-client orchestration layer with observability, dynamic workflows, resumability, background subagents, multi-modal, and cache shape telemetry.
+>
+> **Architecture:** Durable agent execution engine beneath thin chat/coder frontends. Trace system as foundation, workflow engine as the structural addition, everything else layered on top.
+>
+> **Inspired by:** Paseo (agent lifecycle, worktree isolation), Whale (workflow engine, cache telemetry), OpenCode (session resume), Claude Code (workflow script format).
+
+---
+
+## TL;DR
+
+> **Quick Summary**: Build a durable orchestration layer with trace observability, dynamic JS workflows, session persistence, background subagents, and multi-modal support over 5 phases.
+>
+> **Deliverables**:
+> - Trace system with DB persistence + viewer UI
+> - Dynamic workflow engine (JS sandbox, agent/parallel/pipeline)
+> - Workflow resumability (hash-based step caching)
+> - Background subagent runtime
+> - Session persistence across refreshes
+> - Cache shape telemetry (DeepSeek KV cache viz)
+> - Multi-modal attachment support
+>
+> **Estimated Effort**: XL — 5 phases, ~2-3 weeks total
+> **Parallel Execution**: YES — phases 1-2 can partially overlap
+> **Critical Path**: Trace system → Workflow engine → All downstream features
+
+---
+
+## Context
+
+### Original Request
+User wants BooCode to become "like Paseo — a thin client" with observability, dynamic workflows, session persistence, background agents, multi-modal, cache shape telemetry, and workflow resumability. They invoked skills across model evaluation, long context, SGLang, LangChain, LangSmith, agentic eval, agent harness construction, agent governance, and chat SDKs — indicating broad ambition for a production-quality AI coding platform.
+
+### Key Decisions
+- **Trace system first**: Foundation for all debugging and optimization
+- **isolated-vm for workflow sandbox**: Node-native, no external deps
+- **DB-backed sessions**: Postgres for trace store + session state
+- **Existing WS frames + new `tool_trace` frame**: Live streaming to frontend
+- **Phase ordering**: Foundation (trace) → UX (persistence) → Power (workflows) → Polish (background/multi-modal/cache)
+
+---
+
+## Phases
+
+### Phase 1: Trace System + Observability
+**Est. effort**: 3-4 days
+
+Core observability infrastructure. Every tool call gets timed, logged, and persisted.
+
+**Deliverables**:
+- `tool_traces` DB table (id, session_id, chat_id, turn_number, tool_name, input, output, started_at, finished_at, latency_ms, tokens_used, cache_tokens, reasoning_tokens, error, outcome)
+- Instrumentation in `tool-phase.ts` wrapping `executeToolCall` with start/end timing
+- `tool_trace` WS frame type for live streaming to frontend
+- GET `/api/chats/:id/traces` endpoint (paginated)
+- Trace viewer pane (collapsible tree, timing bars, expand/collapse per call)
+
+**Files to create**: 5-7 files across server + web + contracts
+**Dependencies**: None — standalone feature
+
+---
+
+### Phase 2: Session Persistence + Resume
+**Est. effort**: 2-3 days
+
+Agent state survives browser refresh. Active sessions can be resumed.
+
+**Deliverables**:
+- Serialize active agent state to DB on each turn boundary
+- Restore state on WS reconnect (existing `snapshot` frame enhanced)
+- Agent session timeline view (history of all turns in a session)
+- Coder pane rehydrates from persisted state
+
+**Files to modify**: ws.ts, useSessionStream.ts, session store, dispatcher
+**Dependencies**: None — standalone, but benefits from Phase 1 trace data
+
+---
+
+### Phase 3: Dynamic Workflow Engine
+**Est. effort**: 5-7 days
+
+JS sandbox for multi-agent orchestration. Claude Code compatible.
+
+**Deliverables**:
+- `isolated-vm` sandbox (or Node `vm` module with restricted context)
+- Workflow API: `agent()`, `parallel()`, `pipeline()`, `phase()`, `budget()`, `log()`, `args`
+- Workflow file discovery (`.boocode/workflows/*.js` → project, `~/.boocode/workflows/*.js` → global)
+- Built-in workflow catalog (deep-research, multi-review, etc.)
+- Workflow manager with concurrency limits, token budgets
+- Integration with existing Orchestrator panel for UI
+
+**Files to create**: 10-15 files (workflow runtime, scheduler, tool bridge, manager, catalog)
+**Dependencies**: Phase 1 traces feed into workflow observability
+
+**Workflow Resumability** (within Phase 3):
+- SHA-256 hash of agent spec (prompt + options)
+- Cache completed results by hash
+- On re-run, skip cached agents, only execute new/changed ones
+- In-memory cache for current session, optional DB persistence
+
+**Est. effort**: 1-2 days within Phase 3
+
+---
+
+### Phase 4: Background Subagents
+**Est. effort**: 2-3 days
+
+Non-blocking subagent execution. `spawn_subagent` returns immediately, results collected later.
+
+**Deliverables**:
+- Background task queue (reuses existing `tasks` table)
+- `spawn_subagent` tool that creates a task and returns immediately
+- `subagent_status` tool to poll completion
+- `subagent_result` tool to retrieve output
+- Background agent pane showing running/completed subagents
+- Notifications via hooks when background tasks complete
+
+**Files to create**: 3-5 files across server + web
+**Dependencies**: Phase 1 traces, Phase 2 session persistence
+
+---
+
+### Phase 5: Multi-modal + Cache Shape (Polish)
+**Est. effort**: 2-3 days
+
+Image/file attachment support + DeepSeek cache hit visualization.
+
+**Deliverables (Multi-modal)**:
+- Image/file attachment storage (tmpfs, referenced in message)
+- Forward image content through DeepSeek API's multimodal support
+- Render attached images in message bubble
+- Model can "see" screenshots, diagrams, UI mocks
+
+**Deliverables (Cache Shape)**:
+- Extract `prompt_cache_hit_tokens` from DeepSeek provider metadata
+- Build cache segment visualization (system prompt, tool schema, conversation)
+- Per-turn cache hit rate in trace viewer
+- Cumulative cache stats in session view
+
+**Files to create**: 3-5 files
+**Dependencies**: Phase 1 traces (for cache shape), existing DeepSeek integration
+
+---

+
+Removes all remaining Go codecontext sidecar references. The 17 native codecontext tool wrappers (`get_codebase_overview`, `search_symbols`, `get_blast_radius` etc.) have been deleted from the source tree. Code analysis tools are now provided entirely by the boocontext MCP server, discovered at startup via `appendMcpTools()`. All 9 previously unavailable boocontext MCP tools (`get_summary`, `scan`, `get_coverage`, `get_schema`, `get_env`, `get_events`, `get_knowledge`, `get_wiki_index`, `lint_wiki`) are now wired into every relevant agent's tool list in `data/AGENTS.md`. Stale entries removed from `STANDARD_TOOL_NAMES`, `BUILT_IN_TOOLS`, `SYNTHESIS_TOOLS`, and `ToolCallLine.tsx`. Guidance files (`CLAUDE.md`, `BOOCHAT.md`) updated. 22 files deleted (~2,400 lines removed). Pairs with v2.8.20-sidecar-teardown which removed the Docker service.
+
+## v2.8.24-memory-supervisor-streaming — 2026-06-08
+
+Ships the inference state-graph and supervisor architecture — a non-blocking step machine with `StateGraph` nodes and edge transitions, replacing the single-path inference loop. Adds a Supervisor agent (tools: '*' wildcard) for dynamic request routing. Integrates the TypeScript boocontext MCP server for tree-sitter code analysis (health, impact, types). Adds memory management tools (`extract_memory`, `manage_memory`, `search_memory`) for cross-session context persistence. Extends `ws-frames.ts` with `agent_message` channel for inter-agent messaging. PTY sessions gain rich metadata (`description`, `parentAgent`) threaded through the full stack. Web: message-parts components (ActionRow, CompactCard, SummaryCard, ReasoningBlock, StatsLine), ComparePane, Memory page, MCP permission dialog, keyboard shortcuts, ErrorBoundary. Booterm: `sweepExpired()` for idle/absolute timeouts. Conductor: `collision-detector` + `conflict-index` tests. Guidance audit: resolution order, failure modes, refusal discipline across all guidance files.
+
+## v2.8.23-wave2-complete — 2026-06-08
+
+Parallel batch execution and SWITCH branching step for the conductor. `buildBatchState` and `getReadyInBatch` gate agent dispatch concurrency. `SwitchCase` with `resolveSwitch` lets flow steps route via conditionals. Prepares the scheduler for DO_WHILE and FORK_JOIN steps.
+
+## v2.8.22-wave1-complete — 2026-06-08
+
+Paseo hub integration: `paseo-client.ts` (thin HTTP+CLI client) and `backends/paseo.ts` (AgentBackend implementation) for dispatching to Paseo agents. Collision detection: `collision-detector.ts` with `ConflictVerdict` scoring, `conflict-index.ts` with register/sweep lifecycle, `collision_warning` WS frame. PTY search: `search.ts` route with regex-based ring buffer search across PTY session output. Backported from the earlier Wave 1 branch.
+
+## v2.8.21-state-machine — 2026-06-08
+
+Extended the flow-runner task state machine with `TIMED_OUT` status and retriable step support. Steps with `max_retries` auto-retry on failure; `retry_count` tracks attempts. `timedOut` set in SchedulerState gates downstream dependents from running while the timed-out step is retried.
+
+## v2.8.20-paseo-orchestrator-ph3-5 — 2026-06-08
+
+Completes the Paseo-like Orchestrator with phases 3–5. Phase 3 ships a Dynamic Workflow Engine built on Node's `vm` sandbox — Claude Code compatible JavaScript workflows with `agent()`, `parallel()`, `pipeline()`, `phase()`, and `budget()` primitives. Includes a built-in workflow catalog (`deep-research`, `review-code`, `find-issues`) with SHA-256 hash-based resumability cache that skips completed steps on re-run. Phase 4 adds background subagents — `spawn_subagent` returns immediately, `subagent_status` and `subagent_result` tools let the model poll and collect results. Phase 5 adds a cache shape telemetry badge to the trace viewer (colored bar + hit rate percentage) and a multi-modal attachment stub. Also ships inline diff snippets in the chat stream after write tool calls, and the `run_command` tool with auto-fix loop that detects build failures after edits and injects errors for self-correction.
+
+## v2.8.19-paseo-orchestrator-ph1-2 — 2026-06-08
+
+Ships the trace system and session persistence backbone. Every tool call is now timed via `tool_traces` DB table with latency, token counts, cache/reasoning breakdowns, and WS frames streamed live to a new trace viewer pane. Agent sessions survive browser refresh — `agent_snapshots` table persists state on turn boundaries and restores on WebSocket reconnect. A session timeline view shows agent turn history with scroll-to and restore. New frontend components: `TraceViewer` (collapsible panel with timing bars) and `SessionTimeline` (vertical timeline).
+
+## v2.8.18-deepseek-whale-lift — 2026-06-08
+
+Integrates DeepSeek API directly into BooChat and BooCoder via `@ai-sdk/deepseek`, replacing the generic `openai-compatible` wrapper. DeepSeek V4 models (`deepseek-v4-flash`, `deepseek-v4-pro`) with configurable thinking effort levels appear in both chat and coder pane model pickers. Full token tracking — cache hit tokens and reasoning tokens — flow from the API through new DB columns and WS frames into the UI message stats line. Lifts three high-value features from the Whale codebase: a schema-based tool input repair system that coerces types and unwraps markdown autolinks before Zod validation, a shell-based lifecycle hooks system (PreToolUse, PostToolUse, Stop, PreCompact, PostCompact) with JSON stdin/stdout contract, and per-MCP-server permissions (allow/ask/deny) gating tool execution.
+
 ## v2.8.0-fork-lifts — 2026-06-07
 
 Completes the eight fork-lift integrations from `/opt/forks` into BooCode: boocontext sidecar upgrade, LSP code intelligence, DCP clean-room pruning, institutional memory, subagent protocol enhancements, plugin hook host, inference reliability (tool-shim + loop detectors), and TokenScope token breakdown. Backfills edit safety guards (truncation + dropped imports) and the TokenScope analyzer/persist module. Closes the fork-lifts-mit epic.
