chore: snapshot main sync

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).

+# 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
+

+## Tool reliability
+- `edit_file`'s fuzzy match can **succeed on a near-miss** or **return ambiguous** when `old_string` matches multiple locations. Always verify the queued diff before calling `apply_pending` — the diff preview is authoritative, the tool's "success" return is not.
+- The external agent's worktree diff only shows changes since the **last turn**, not since the project baseline. The DiffPanel merges these, but if you call `git diff` directly, you'll get incomplete results.
+
 ## Pending changes discipline
 
 Every file modification queues in `pending_changes` before touching disk. The user sees a diff preview and approves/rejects each change. Never bypass this queue — it is the safety boundary between inference and the filesystem.

-## v2.8.0-fork-lifts — 2026-06-07
+## v2.8.30-main-sync - 2026-06-17
+
+Snapshot tag for the current `main` line after the recent cross-app integration work. Carries the BooControl fleet cockpit (`apps/control` plus the `/control` web surface), provider/inference reshaping across BooCoder and BooChat, boocontext-oriented guidance and skill updates, web workspace/API cleanup, and the `docs/how-to-build-a-coding-agent/` example project. Also removes the stale `.codesight/` cache from version control. This tag is a synchronization checkpoint rather than a single feature slice; see the commit history around `1f32bb0` for the exact file-level batch.
+
+## v2.9.0-boocontrol - 2026-06-13
+
+Ships BooControl, the fleet cockpit for the llama-swap hosts: a new host service `apps/control` (Fastify, port 9503, third schema owner on the shared `boochat` Postgres) plus a `/control` page in `apps/web` (React + ECharts) proxied through `apps/server` via `registerControlProxy` (`/api/control/*`). Cockpit tabs: Fleet (live host cards with VRAM/temp/power, model-state chips, TTL rings, collapsible perf history), Activity, Logs, Playground, Bench, Evals, Jobs (unified bench/eval/pull progress from the `control_job` stream), Routing (route-policy editor + gateway dispatch log), and Reports (scheduled markdown digests). P4 attribution threads `X-Boo-Source` end to end. P6 advisory scores badge the model picker ("best code model now"). P7 adds a live `auto:*` gateway: OpenAI-compatible virtual models backed by `route_policies` with health-filtered candidate ordering, failover, a cold-start live-fleet fallback, and `X-Boo-Source` forwarding; `resolveModelProvider` gained `gateway`/`gateway_error` route variants so orphaned `auto:*` sessions fail loud instead of mis-routing to `LLAMA_SWAP_URL`. P9 ships an SSH config editor (read/validate-against-the-fork-schema/diff/backup/write/restart/health-wait) with a per-host `shell`/`wrapper` mode (forced-command-locked key) and HuggingFace model pull. The cockpit's WS singleton (`useControlStream`) carries a connection-status pill and per-host snapshot/delta seqs. P8 (cross-service fleet-coordination lease) is an outline only under `openspec/changes/fleet-coordination-lease/`. Deploy is a host service like boocoder; see `openspec/changes/boocontrol-finish/runbook.md`. Builds + suites green: contracts 29, control 178, coder 587, server 598 (DB-gated), web tsc clean.
+
+## v2.8.25-codecontext-removal - 2026-06-08
+
+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.
 
 **boocontext sidecar (Phase 3):** Upgrades the `codecontext` container from the old Go MCP server to the boocontext Node.js MCP aggregator. Multi-stage Dockerfile builds boocontext from `/opt/forks/boocontext` alongside the HTTP shim. `shim.go` gains `CODECONTEXT_CHILD` env-var support and three new HTTP routes for symbols, callgraph, and blast radius. Three TypeScript tool wrappers (`get_symbol_details`, `get_call_graph`, `get_blast_radius`) registered on the server, with blast radius added to the synthesis pipeline. Docker-compose env vars configure child MCP paths (tree-sitter-analyzer, type-inject).
 
-**LSP integration (Phase 4):** Six-file `lsp/` module in the coder with config, JSON-RPC stdio client, lazy server-manager (per-project pool, 5-min idle shutdown), and operations (diagnostics, goto-definition, find-references). Three read-only agent tools registered — `lsp_diagnostics`, `lsp_goto_definition`, `lsp_find_references`. TypeScript/JavaScript only in v1.

-**DCP clean-room (Phase 5):** Seven-file `dcp/` module in the server inference pipeline. Consecutive identical tool_call+tool_result pairs are deduplicated; failed/empty tool results are purged via configurable window. Orchestrated by `transformMessages()` running before `buildMessagesPayload` in `turn.ts`. Clean-room reimplementation — AGPL source was referenced for behavior only. 10 unit tests.

-**Institutional memory (Phase 6):** Eight-file `memory/` module with file-based recall. Hierarchical 4-scope scan (global → home → project → session) under `.boocode/memory/`. Keyword/tag relevance matching at prompt assembly. Injected as a `<boocode-memory>` block in the system prompt. v1 recall-only — extract/dream deferred.

 **Subagent protocol (Phase 7):** `AgentCapabilitiesSchema` in contracts with `supportsStreaming`, `supportsReasoningStream`, `supportsBackgroundExecution` flags. `ProviderSnapshotEntry` gains the two streaming capability fields. `new_task` tool gets a `background` mode flag for non-blocking dispatch. Flow-runner already supported per-step model override.
 
-**Plugin host (Phase 8):** Typed hook registry in `plugins/host.ts` with `registerHook`/`emitHook` for five lifecycle events: `tool.execute.before`, `tool.execute.after`, `turn.start`, `turn.end`, `task.terminal`. Patterns-only from oh-my-openagent (SUL — no code copy).

-**Inference reliability (Phase 9):** `tool-shim.ts` recovers XML/JSON tool calls from plain-text model output (e.g. Qwen inline format). `loop-detectors.ts` catches content-repeat and tool-loop patterns. Existing doom-loop detection remains — detectors are additive.

 **Edit safety guards (Wave 1):** `edit-guards.ts` rejects catastrophic truncation (>60% chars AND >50% lines). `edit-guards-imports.ts` detects dropped import statements. Both run in `pending_changes.ts` immediately before `writeFileAtomic`.
 
 **TokenScope (Wave 2):** `TokenBreakdownSchema` in contracts with system/user/assistant/tools/reasoning categories. `token-analysis/` module with analyzer and DB persistence. `ContestantShape.token_breakdown` field and `token_breakdown` JSONB column on `contestants`/`tasks` tables. Arena `computeBenchmark` accepts and returns token breakdown.

-Adds the **Arena** pane for running the same prompt against 2–6 AI competitors simultaneously and picking the best result. A Battle is one Arena run: pick a battle type (Coding — backend+model with git worktrees producing diffs; or Q&A — BooChat persona+model producing text), write or generate a prompt, add contestants, and hit Start. Contestants are scheduled in two concurrent lanes — the local lane (llama-swap models, serial) and the cloud lane (Claude Code, OpenCode-on-cloud, parallel). The lane scheduler captures wall-clock duration for every contestant and tokens/sec for local models. When all contestants finish, a two-stage analysis (digest then judge) auto-runs on the DEFAULT_MODEL, writing `analysis.md` naming a winner; the user can override the winner per-row or trigger cross-examination. Results land in `/<project-root>/Arena/<dated-battle>/` with per-contestant `result.md`, diff patches for coding, and `manifest.json`. Replaces the old API-only `POST /api/arena` with dedicated `battles`/`contestants`/`cross_examinations` tables and full UI. Also adds a `DiffView` component with line-by-line colored unified diff and a per-row dropdown for winner override. Built on `v2.7.18-permission-modes`; pairs conceptually with the earlier `v2.7.17-orchestrator` multi-agent work (both share the pane kind pattern and `onTaskTerminal` hook).

-## v2.7.18-permission-modes — 2026-06-05
+## v2.7.18-permission-modes - 2026-06-05
 
-Adds a unified **permission picker** to the BooCoder composer — Plan / Ask Permission / Bypass — replacing the old raw per-agent mode dropdown that exposed each agent's full native vocabulary with inconsistent labels. The three options map generically onto every provider's existing mode metadata: the `plan`-id mode → Plan, the default mode → Ask, the `isUnattended` mode → Bypass (claude `bypassPermissions`, qwen `yolo`, opencode `full-access`); goose has no modes so it shows no picker, exactly as before. `modeId` stays the single wire field — the active unified mode is derived from it, so no contracts change was needed. Native BooCode gains its own mode set (registered in the manifest and exposed by the snapshot): **Ask** stages edits to the pending-changes queue as today, **Bypass** auto-applies the queue to disk after the turn (both the interactive messages path and the task-based dispatcher path), and **Plan** falls back to Ask — the shared `apps/server` inference engine is deliberately left untouched. A supporting fix preserves the `isUnattended` flag on live-probed ACP modes (`acp-derive.ts`) so opencode's bypass mode is still detectable from the wire. Coder 373 tests green, coder + web typecheck clean. Built on `v2.7.17-orchestrator`.

-Brings the deterministic multi-agent "conductor" into the app as the **Orchestrator**: launch any read-only Han flow (research, code-review, investigate, architectural-analysis, security-review, …) from BooChat or BooCoder and watch each specialist agent stream live in a Paseo-style run pane, ending with an evidence-disciplined, adversarially-validated report — all on free local Qwen, persisted and resumable. Built and audited end-to-end via `paseo-epic` in an isolated worktree, on top of the prior `/opt/boocode/conductor` standalone CLI: the conductor's 22 flow definitions, Spine factory, and Han evidence/YAGNI contracts were re-homed into `apps/coder/src/conductor`, and a new DB-backed flow-runner (`flow_runs`/`flow_steps`) dispatches each step as a real BooCoder task through the existing dispatcher — reusing its streaming→WS-frame pipeline and worktree-as-read-snapshot, with an `onTaskTerminal` hook that advances the wave and a startup resume that re-dispatches in-flight steps after a coder restart. Read-only is enforced hard: every step is dispatched `qwen --approval-mode plan`, an adversarial-security review caught and closed a bypass where a qwen-unavailable task silently fell through to write-capable native inference (now fails closed), and the ACP path's mode-set was made fail-closed too. The UI adds a fourth `orchestrator` pane kind (collapsed agent roster, expand-one live stream, report on top), a Workflow button + slash flows on the shared `ChatInput` for full BooChat/BooCoder parity, a "New Orchestrator" entry in the + and split menus, a category-grouped launcher dialog, runs history, and export (copy / save-to-file / send-to-chat) — fed by two new `flow_run_*` WS frames on a coder user channel. Qwen-only by design (Claude Code remains the Claude path); the existing model-competition Arena stays a separate feature. The flow launcher and the `/` slash menu both carry chevron-expandable per-item explanations (an always-on one-liner expands to a 1–2 sentence what-it-does / when-to-use blurb, condensed from each Han skill's own description), with a "read-only" pill pinned in the launcher and the fast/concise toggle wired through to the workers.

-Hotfix that makes the `v2.7.15-git-diff-panel` work in production. The `boocode` container runs as root but bind-mounts host project repos owned by uid 1000, so git rejected them with "detected dubious ownership" and the diff route reported every project as not-a-repo — which hid the Git tab entirely (and had been silently nulling the existing branch indicator too). Adds `git config --system --add safe.directory '*'` to the Dockerfile runtime stage so the container's git trusts the mounted repos; applied live to the running container and baked into the image for future rebuilds. Surfaced by a live smoke immediately after the v2.7.14/v2.7.15 deploy.

-A Files / Git tab in the right-side file panel (the file-browser sidebar) that shows the project repository's git diff and lets the user stage, unstage, commit, and discard whole files in-session — modeled on Paseo's diff view, scoped and planned through the `plan-a-feature` → `plan-implementation` skills, then built and audited via `paseo-epic` in an isolated worktree. Two comparison modes (Uncommitted vs HEAD, and the current branch vs its base — the upstream tracking branch else `origin/HEAD`), auto-selected by repo dirty-state on first open and pinned after an explicit choice; per-file expand/collapse with lazy Shiki `lang:'diff'` highlighting, +/- stats, and binary/too-large placeholders. All git read and write logic lives in `apps/server` (new `git_diff.ts` + routes on `projects.ts`) — the read-only-server posture governs the assistant's tools, not the user's own actions, and the container already mounts `/opt` read-write while `project_bootstrap` already commits via `execFile`. Every write uses the safe `execFile` argv pattern (never a shell string) with `--` operand separators, per-file `pathGuard` + realpath symlink-escape validation, server-derived `-c` commit identity (the request body is `.strict()` and carries no author fields), and the write endpoints are deliberately absent from the assistant tool registry. Reads are bounded (30s deadline, 10MB); an index lock or an in-progress merge/rebase/cherry-pick/bisect surfaces as "repository busy" and disables writes. The panel stays current via a client `git_diff_refresh` sessionEvent (no new wire contract) coalesced across tab-open, mutations, turn completion, and pending-change apply; discard is an irrecoverable hard-delete behind a plain confirm distinguishing a tracked revert from an untracked delete. New `git_diff` pure-helper + temp-repo integration tests (59 cases); server 630 tests green, web tsc clean. Pairs with `v2.7.14-backlog-hardening` (shipped together).

Every write uses the safe `execFile` argv pattern (never a shell string) with `--` operand separators, per-file `pathGuard` + realpath symlink-escape validation, server-derived `-c` commit identity (the request body is `.strict()` and carries no author fields), and the write endpoints are deliberately absent from the assistant tool registry. Reads are bounded (30s deadline, 10MB); an index lock or an in-progress merge/rebase/cherry-pick/bisect surfaces as "repository busy" and disables writes. The panel stays current via a client `git_diff_refresh` sessionEvent (no new wire contract) coalesced across tab-open, mutations, turn completion, and pending-change apply; discard is an irrecoverable hard-delete behind a plain confirm distinguishing a tracked revert from an untracked delete. New `git_diff` pure-helper + temp-repo integration tests (59 cases); server 630 tests green, web tsc clean. Pairs with `v2.7.14-backlog-hardening` (shipped together).

-Hotfix for the coder model-attribution chip vanishing on refresh. The chip showed during a live turn (the `message_complete` frame carries `model`) but disappeared when a BooCoder session was reloaded — only in the coder, not BooChat. Root cause: `CoderPane`'s `useCoderMessages` hydrates from two sources on load — the HTTP `listMessages` fetch (whose SELECT includes `model`, added `v2.7.8`) AND the WS `snapshot` frame — and the WS snapshot's query in `apps/coder/src/routes/ws.ts` had its own column list that omitted `model`. The client's `snapshot` handler `setMessages`-overwrites the HTTP load, so the model-less rows won, and with no later `message_complete` for historical messages the chip stayed gone. Fix is one column: add `model` to the WS snapshot SELECT so both hydration paths agree. The `apps/coder/CLAUDE.md` "update every mapper" note now lists the WS snapshot SELECT explicitly (it was the one place not enumerated). apps/server + apps/coder builds green; deployed via `systemctl restart boocoder` (host service — the earlier `v2.7.10` docker deploy rebuilt only the container, never this route).

Also fixes a coder-side correctness bug: `resolveChatId` (`apps/coder/src/routes/chat-resolve.ts`) still read `sessions.workspace_panes` as a bare `WorkspacePane[]`, but `v2.6.5-panes-tabs-composer` widened it to a `WorkspaceState` envelope — so it mis-read the panes and, worse, clobbered `tabNumbers`/`nextTabNumber`/`closedPaneStack` back to a bare array on every pane-chat write; a new `normalizeWorkspaceState` accepts either shape and preserves the envelope (with a regression test).

-The scoped half of `boocode_code_review_v2.md` §1 #10 — normalized external-agent status, surfaced from BooCoder's own dispatch observation (the heavier config-injection notify-hook, clean-room from superset's ELv2 `agent-setup`, is documented as the follow-on). The review's premise ("PTY agents have no status") had partly aged out — warm-ACP/opencode/SDK already carry working/done — so the real gap was that BooCoder never *published* a normalized per-`(chat,agent)` status (blocked-on-permission was invisible; crash/idle weren't pushed). Adds an `agent_status_updated` WS frame (`working|blocked|idle|error`, server+web parity) published from the dispatcher's turn boundaries across all four external paths (warm-acp/opencode/sdk/pty — `working` at start, `idle`/`error` at end) and the permission flow (`blocked` on request, `working` on resolve), best-effort so it never breaks a turn. A clean-room `normalizeAgentEvent` helper (superset's ~30-vendor-event → Start/blocked/Stop collapse, reimplemented with the event names as facts) ships now with 25 tests so the deferred notify-hook injection reuses it verbatim. The `AgentComposerBar` gains a normalized status dot (working=spinner, blocked=amber, idle=gray, error=red) distinct from the WS-liveness dot, fed by a `useAgentStatus` map `CoderPane` tracks per `(chat,agent)`. Built by two parallel agents (data plane + view plane) against a pinned frame contract; server 545 + coder 294 tests passing (25 new), web tsc + builds clean, ws-frames parity green.

Built against the REAL SDK 0.3.159 types after installing it — surfacing shapes a blind build would have missed (`SDKPartialAssistantMessage` is `type:'stream_event'` needing `includePartialMessages`; `SDKUserMessage.message` is `MessageParam`; the `SDKResultMessage` error arm). Also fixes a latent test-infra deadlock — three DB-integration suites applying the full schema in parallel under `DATABASE_URL` deadlocked, now serialized via `fileParallelism:false`. ~32 new tests (8 store + 10 mapper + 8 pushable + 6 routing); coder suite 269 passing default / 290 with DB; tsc clean against the SDK types; builds clean. **The live streaming pump + resume + an actual claude turn need a host smoke (`CLAUDE_SDK_BACKEND=1` + claude binary + ANTHROPIC auth) — cannot run from the dev container.** The zod peer-dep wants `^4` (workspace `3.25`) — watch at runtime.

-Two native-inference hardening features from `boocode_code_review_v2.md` §1 #12 (cline, algorithm-reimplemented). **MistakeTracker:** complements the doom-loop guard (identical repeats) and cap-hit (budget) by catching a run of consecutive tool *failures*. A new pure `mistake-tracker.ts` tracks heterogeneous failure kinds (`zod_reject`/`tool_not_found`/`exec_error`/`api_error`/`permission_denied`, surfaced per tool from `tool-phase.ts`); after 3 consecutive failures the `turn.ts` loop does a **soft nudge** — injects model-facing recovery guidance into the next step + drops a `mistake_recovery` UI sentinel + resets — then **escalates** to stopping the turn (cap-hit-style, with a Continue affordance) if it re-trips without an intervening success, so heterogeneous failures can't burn the whole step budget. **File-provenance ledger:** `compaction.ts` now derives a deterministic, sorted `## Files Read` list from the head messages' read-tool calls (`view_file`/`grep`/`find_files`/`list_dir`) and injects it into the rolling-summary prompt so file provenance survives compaction (no new table; prompt-driven merge, read-only since BooChat has no write tools). The `mistake_recovery` sentinel adds an arm to `MessageMetadata` in both server + web type copies plus a `MessageBubble` render branch. Built by two parallel agents (backend + frontend sentinel) over disjoint apps; server 545 tests passing (23 new: 12 mistake-tracker + 11 compaction), build + web tsc clean.

This surfaced and fixed a **latent bug**: `top_k` (rejected by the AI-SDK provider as unsupported) and `min_p` (never passed to `streamText` at all) had been dead on the wire — no agent's `top_k`/`min_p` ever affected sampling; both now route through the same channel, so agents that set them will start using them. `--reasoning-budget` is documented in `data/AGENTS.md` (already works via `llama_extra_args`, permitted by the deny-list validator). **Live PTY stream-json:** qwen/claude PTY dispatch sliced stdout opaque; a new `stream-json-parser.ts` line-buffers the Claude-Code-compatible NDJSON and emits text/reasoning/tool frames live as they arrive (mirroring the ACP/opencode paths) + persists the structured parts, with a clean fallback to the old opaque slice when output isn't NDJSON (claude now runs `--output-format stream-json --verbose`). **Token UI:** the per-`(chat,agent)` `agent_sessions.input_tokens`/`output_tokens`/`cost` columns (accumulated since `v2.6.8` but dropped by the read route + wire type) now flow through and render condensed beside the AgentComposerBar session chip.

The `GET /api/sessions/:id/checkpoints?chat_id=` list route scoped its `chat_id` branch by `chat_id` alone — any session's `chat_id` would read its checkpoints; it now joins through `chats` and gates on `chats.session_id` (authoritative; `checkpoints.session_id` is a nullable denormalized hint). The `restoreCheckpoint` scope guard was fail-open — `cp.session_id && cp.session_id !== sessionId` fell through whenever the checkpoint's denormalized `session_id` was null, allowing a cross-session restore (worktree reset + transcript trim) — it now resolves the owning session via the checkpoint's chat and denies on any missing-or-mismatched row. A DB-integration regression covers the exact null-`session_id` cross-session case. Real-world blast radius is small (BooCoder is single-user behind Authelia on loopback), but both are genuine authorization bugs.

A new `POST /api/sessions/:id/checkpoints/:cid/restore` resets the worktree (`reset --hard` + `clean -fd`), trims the transcript past that message, and resets the `(chat,agent)` backend session so files, transcript, and agent context land consistent at the restore point; a per-message "Restore to here" affordance in `CoderMessageList` drives it.

-v2.6 Phase 3 (the last phase) — lifecycle hardening of the warm-process backends. **Idle eviction + LRU cap:** the agent pool runs a 60s sweep that evicts backends/sessions idle past `AGENT_POOL_IDLE_TTL_MS` (30 min default) and any beyond `AGENT_POOL_MAX_LIVE` (10, LRU) — **never a busy one** (in-flight turn, double-checked via a new `isBusy()` backend hook); the worktree persists (DB-backed) and the next turn re-spawns + reattaches. The eviction/LRU/restart decisions are factored into a pure `lifecycle-decisions.ts` (modeled on the inference `selectPruneTargets` pattern). **Crash recovery:** lifts openchamber's health-monitor + busy-aware-restart + consecutive-failure + stale-busy-grace state machine into `opencode-server.ts` (with port reclaim) and `warm-acp.ts` — an opencode server crash settles in-flight turns as failed, marks the rows `crashed`, and recreates fresh sessions (a fresh server can't hold the old in-memory id), while a warm-ACP child crash re-`session/new`s next turn; the F.1 turn-guard and U.6 usage are preserved (their tests still pass). **Worktree reaper:** a periodic reaper removes orphan on-disk worktrees (no live `worktrees` row, 1h grace) behind a superset-style preflight that skips dirty/unpushed/unmerged work, with Paseo-style soft-delete (`status='archived'`). Plus close hooks (`/api/chats/:id/close`, `/api/sessions/:id/close`, awaiting the apps/server caller) and diff re-baseline after `apply_pending`. Built test-first — 35 new tests (`lifecycle-decisions` 22, `agent-pool` 13) + a DB-opt-in reconnect integration test; 215 coder tests pass, tsc + build clean. **This completes v2.6** (Phase 0–3 + F.1 + Phase 1-UX).

-v2.6 Phase 2: goose and qwen now run as **warm ACP backends** instead of one-shot-per-task. A new `WarmAcpBackend` (`backends/warm-acp.ts`, implementing the same `AgentBackend` interface as the opencode warm server) holds one persistent `goose acp` / `qwen --acp` child + `ClientSideConnection` + ACP session per `(chat, agent)`, running `initialize` + `session/new` once and reusing the connection across turns; per-turn abort cancels the in-flight prompt (`session/cancel`) without killing the child, and a child exit marks `agent_sessions.status='crashed'` for re-spawn on the next turn. The dispatcher routes `goose`/`qwen` chat-tab tasks to the pooled warm backend via a pure `shouldUseWarmBackend(task)` predicate (warm only when both `session_id` and `chat_id` are set), keeping the one-shot `runExternalAgent` path as the fallback for session-less creators (arena, MCP, `new_task`); broker frames + `persistExternalAgentTurn` + the latest-wins `pending_changes` diff are identical to the opencode path. The `acp-dispatch.ts` `handleSessionUpdate` switch was extracted into a pure shared `acp-event-map.ts` mapper used by both the one-shot and warm paths (one-shot behavior byte-identical, all existing acp tests green). The design's `unstable_resumeSession` concern is resolved — the installed `@agentclientprotocol/sdk@^0.22.1` exposes stable `resumeSession`/`loadSession`, but resume is moot in the hot path (warm reuse needs none); cross-restart resume + idle eviction are deferred to Phase 3. Built test-first (15 new tests: `warm-acp-routing`, `acp-event-map`); 180 coder tests pass, tsc + build clean. **Smoke 2/2b (live two-message warm reuse + the opencode→boocode→opencode switch round-trip) to be run post-deploy.** Phase 3 (lifecycle hardening) is the last v2.6 phase.

Built by three parallel subagents over disjoint file sets; web + coder typecheck clean, 165 coder tests pass (9 new across `opencode-usage` and `agent-sessions.routes`).

-Fixes a post-interrupt correctness bug in the `v2.6.1-phase1-opencode` warm-server backend, made one-click reachable by `v2.6.5-panes-tabs-composer`'s Send→Stop composer. `opencode-server.ts` settled an in-flight turn on opencode's `session.idle`/`session.error` by calling `activeTurn.settle()` on whatever turn currently held the session slot — but opencode emits one trailing terminal event for a *cancelled* turn after `client.session.abort()`, and those events carry only a `sessionID` (no turn id). So after the user hit Stop and immediately sent another message, the aborted turn's orphan `session.idle` settled the *new* turn early as success (Paseo hit and fixed the same class in `1d38aac`). The fix adds a small pure guard (`turn-guard.ts`: `armAbortGuard`/`noteTurnActivity`/`consumeTerminal` over a per-session `swallowNextTerminal` flag): abort arms it, the next terminal is swallowed once, and a new turn's first delta self-heals the flag so a never-arriving orphan can't strand a real turn. Implemented test-first — three regression tests in `turn-guard.test.ts` (swallow-the-orphan, settle-when-no-abort, self-heal); full coder suite green (156 passed). This is the F.1 "fix-next" item from the v2.6 openspec reconciliation; Phase 1-UX / Phase 2 / Phase 3 remain.

The per-message "Open in pane" artifact button was removed, and the empty/landing pane became a real session history — the session's open chats plus separately-fetched archived chats, click to open or restore-and-open. **Persistence:** `sessions.workspace_panes` was widened from a bare `WorkspacePane[]` to a `WorkspaceState` envelope (`panes` + `tabNumbers`/`nextTabNumber` + `closedPaneStack`) so tab numbers and the reopen stack survive reload; the PATCH validator accepts the legacy array or the envelope (zod union) and migrates on write, and the `session_workspace_updated` WS-frame schema was widened on both web and server (byte-identical, parity test green) — the same schema-drift class as `v2.6.4-agent-sessions-fk`. **Composer:** the send button morphs Send → Stop → Queue with generation state (BooCoder keys on `sending || activeTaskId`, which also corrected its queue gates and added `cancelTask`), the standalone "Stop generating" pill was folded into it, and pasted chips now trail the typed text so a leading slash command stays first. **Tooling:** adds the read-only `read_tab_by_number` tool — resolves a session-scoped tab number to its chat via the persisted `tabNumbers` map and returns that chat's transcript; tools gained an optional `ToolExecCtx` (`{ sql, sessionId }`) on `execute` to support DB-reading tools.

The P1.5-b re-key block re-adds `session_id_fkey` as `SET NULL`, but the whole block is guarded on `chat_id_fkey`'s absence — so a database already re-keyed to `(chat_id, agent)` while `session_id_fkey` was still `CASCADE` never re-enters it, leaving the live FK at `CASCADE` and diverging from both `worktree_id` (already `SET NULL`) and the `v2.6.3` changelog's own claim that `session_id` is informational `SET NULL`. The fix adds a standalone `confdeltype`-guarded `DO` block (mirroring the `session_worktrees` defang) that flips `session_id_fkey` `CASCADE → SET NULL` independently of the re-key gate; it is idempotent — fires only while the FK is still `'c'`, a no-op on a fresh deploy (already `'n'`) and on every re-run. The live DB was converged by hand with the identical statements, so `applySchema` and the hand-applied state match (`\d agent_sessions` now shows `session_id ... ON DELETE SET NULL`). Also bundles a CLAUDE.md doc-sync (committed separately): per-session SSE (P1.5-a) and the `(chat_id, agent)` re-key reflected in the engineering notes, the stale root `AGENTS.md` navigation pointer dropped, and new conventions for `data/AGENTS.md` parsing and the `data/skills/<vendor>/` layout.

-Three threads. **agent_sessions re-keyed to `(chat_id, agent)` (P1.5-b):** the tab (a chat) is now the agent-context unit, so two opencode tabs in one BooCode session are two independent contexts that share one worktree. `chat_id` is threaded end-to-end — `tasks.chat_id` added, stamped by the coder message + skills routes from the frontend tab, read by `runOpenCodeServerTask` which falls back to resolve-or-create a chat for session-less creators (arena/MCP/new_task/generic `/api/tasks`) so `ensureSession` never receives a degenerate `(null, agent)` key. A new first-class `worktrees` table (one-per-session, survives session delete via `session_id ON DELETE SET NULL`) supersedes `session_worktrees`, which is defanged (CASCADE dropped, not yet removed); `agent_sessions.chat_id` CASCADEs from `chats` (closing a tab ends its context) while `worktree_id`/`session_id` are informational `SET NULL`. The migration is idempotent with a backfill-verify gate; the live re-key was applied against an empty table after the 35-chat test session `20d28876` was deleted (backed up first). This corrects and supersedes an earlier draft that wrongly keyed on `(worktree_id, agent)`; the delete-guard from `v2.6.2-delete-guard-and-sse` is repointed here from `session_worktrees` to `worktrees` (`worktree_path`→`path`). **dcp-strip cross-chunk fix:** the `<dcp-message-id>` tag streams split across SSE deltas, which the per-chunk strip from `v2.6.1-phase1-opencode` missed — a stateful `makeDcpStreamStripper` at the dispatcher boundary holds back partial-tag tails so neither live frames nor persisted content carry the tag (11 unit tests). **Agent-judgment skills:** `committing-changes` (segment by concern, stage explicitly, present-and-stop, never push) and `using-worktrees` (the when-to-isolate heuristic, autonomous-when-clear vs committing's command-gate) land in `data/skills/boocode/` with eval.yamls, plus a parser-safe `data/AGENTS.md` preamble pointing at both.

A new first-class `worktrees` table (one-per-session, survives session delete via `session_id ON DELETE SET NULL`) supersedes `session_worktrees`, which is defanged (CASCADE dropped, not yet removed); `agent_sessions.chat_id` CASCADEs from `chats` (closing a tab ends its context) while `worktree_id`/`session_id` are informational `SET NULL`. The migration is idempotent with a backfill-verify gate; the live re-key was applied against an empty table after the 35-chat test session `20d28876` was deleted (backed up first). This corrects and supersedes an earlier draft that wrongly keyed on `(worktree_id, agent)`; the delete-guard from `v2.6.2-delete-guard-and-sse` is repointed here from `session_worktrees` to `worktrees` (`worktree_path`→`path`). **dcp-strip cross-chunk fix:** the `<dcp-message-id>` tag streams split across SSE deltas, which the per-chunk strip from `v2.6.1-phase1-opencode` missed - a stateful `makeDcpStreamStripper` at the dispatcher boundary holds back partial-tag tails so neither live frames nor persisted content carry the tag (11 unit tests). **Agent-judgment skills:** `committing-changes` (segment by concern, stage explicitly, present-and-stop, never push) and `using-worktrees` (the when-to-isolate heuristic, autonomous-when-clear vs committing's command-gate) land in `data/skills/boocode/` with eval.yamls, plus a parser-safe `data/AGENTS.md` preamble pointing at both.

-Two coder-side batches under one tag. **Session-delete work-loss guard:** deleting a BooChat session CASCADE-wipes its `session_worktrees` row, which would silently orphan uncommitted/unpushed/unmerged work — so the server's `DELETE /api/sessions/:id` now gates before the delete. It reads `session_worktrees` from the shared DB first (no row → chat-only session → delete immediately, zero round-trip), and for worktree-backed sessions calls a new BooCoder endpoint (`/worktree-risk`) that runs git on the host, since the container can't see `/tmp/booworktrees` — only the host systemd service can. `checkWorktreeWorkAtRisk` reports dirty/unpushed/unmerged via the audited `hostExec`+`shellEscape` path, default branch detected from `refs/remotes/origin/HEAD` (never the worktree's own branch, never hardcoded); any at-risk worktree returns 409 with per-worktree `RiskReport[]`, `force=true` bypasses, and the check is fail-closed (BooCoder unreachable also blocks — force still escapes). The sidebar renders a block dialog distinguishing work-at-risk (Commit/Stash/Force; stash uses `-u` and re-blocks on remaining commits) from couldn't-verify (Cancel/Force), and Commit never auto-commits. A follow-up fix gates the `unpushed` arm behind an actual upstream (`atRisk = dirty || unmerged > 0 || (hasUpstream && unpushed > 0)`) so the no-upstream `session-<id>` branches stop flagging every pristine worktree-backed session — no protection lost, since real local work always also surfaces as `unmerged > 0`. **Per-session SSE (P1.5-a):** replaces the single global SSE loop scoped to the most-recent worktree directory — the known limit flagged in `v2.6.1-phase1-opencode` — with one `event.subscribe({directory})` per live opencode session, so sessions in different worktrees stream concurrently instead of the second silently dropping the first's events. Each session owns an `AbortController` wired into `subscribe(…, {signal})`, which also fixes a latent Phase-1 bug where switching directories left the old loop parked forever in its `for await` (zombie loops); a `sessionID` demux guard drops cross-session events so two sessions sharing a worktree (possible after P1.5-b) don't double-process deltas. The opencode SDK was confirmed to open an independent SSE connection per `subscribe()` call, so N concurrent dir-scoped streams are supported.

Builds on the `v2.6.0-phase0-foundations` schema/interface scaffold.

-Security fix + repo hygiene. Fixes a path-traversal in the ACP filesystem bridge (`acp-client-fs.ts`, flagged by the automated push security review): the worktree guard used an unbounded `startsWith(resolve(worktreePath))`, so a sibling path sharing the worktree as a string prefix (`<worktree>-evil/…`) escaped the scope — and `writeWorktreeTextFile` writes to disk directly (no `pending_changes` gate), so a confused/buggy ACP agent could write outside its worktree. Now uses a separator-bounded check matching `write_guard.ts` (`resolve()` + `startsWith(root + sep)` / `=== root`) via a shared `resolveInWorktree`, with a regression test covering `../` traversal and the sibling-prefix bug. Symlink-swap/`O_NOFOLLOW` hardening was intentionally skipped — consistent with `write_guard`'s no-realpath stance, and the agent already runs with host FS access so this is a containment guard, not a trust boundary. Separately, stops tracking the live `data/coder-providers.json` (it's runtime config the UI reads *and writes* on provider toggles, which churned `git status`) — it's now gitignored with a tracked `data/coder-providers.example.json` reference; the loader falls back to built-ins-only when the live file is absent. The provider-type duplication (coder ↔ web) stays guarded by the existing text-identity `provider-types-parity.test.ts` — a shared package was considered and declined (drift is already prevented; not worth the Docker/build-order risk at solo scale).

-Closeout of the v2.3 provider-lifecycle batch — the web UI (Phase 5) plus docs (Phase 6). Provider management moved into **Settings → Providers**: a tab listing every registered provider with a status badge (Available / Disabled / Not installed / Error / Loading), an enable/disable toggle, a per-provider refresh, and a plaintext diagnostic; toggling sends the provider's *full* override (preserving a custom ACP entry's command under the wholesale-replace PATCH merge) then refetches the snapshot. The composer's provider picker now filters to `enabled && (status === 'ready' || 'loading')`, so disabled and unavailable providers drop out of the picker and are managed only in settings (native `boocode` always shows). A curated ACP catalog (`apps/web/src/data/acp-provider-catalog.ts`) + `AddProviderModal` register custom providers via `PATCH /api/providers/config` then a subset refresh, and the web client gained `getProvidersConfig` / `patchProvidersConfig` / `refreshProviders` / `getProviderDiagnostic`. Two mobile fixes ship alongside: the Settings pane is now reachable on phones (opening it pushes `?pane=` atomically so the mobile URL-sync effect keeps it active instead of snapping back to the chat pane), and the Add-provider modal caps to the viewport with a single `overscroll-contain` scroll region so the list scrolls instead of dragging the whole modal. This completes the arc begun in `v2.5.4-provider-lifecycle-phase1` (config-backed registry over the built-ins) → `v2.5.5-provider-lifecycle-phase2` (loading/unavailable snapshot lifecycle + tier-2 probe TTL gate) → `v2.5.6-provider-lifecycle-phase3` (generic `resolveLaunchSpec` ACP dispatch) → `v2.5.12-provider-lifecycle-phase4` (config GET/PATCH, subset refresh, diagnostic HTTP API). Docs landed in `BOOCODER.md` (config file, refresh contract, enable/disable, custom ACP, the honest subset-refresh known limitation) and `docs/DEFERRED-WORK.md` §2 is marked addressed; the remaining Tier-2 follow-ups (WS `provider_snapshot_updated` frame, `available_agents.enabled` column, shared types package, MCP provider tools) stay deferred.

(2) Captured commands are persisted to a new `available_agents.commands` JSONB column and served (merged with the manifest) on the tier-2-probe-skip path, so the agent's discovered commands survive once the model list is warm and show without a dispatch.

-Segmented per-agent slash menu in the coder pane, plus cross-agent skills. The `/` menu now shows two labeled groups — **the active agent's commands first** (opencode/claude/qwen manifest + live ACP `available_commands`), **BooCoder skills second** — instead of always showing BooCoder's skills regardless of provider. `SlashCommandPicker` gains an opt-in `groups` prop (the flat `items` path is unchanged, so **BooChat's menu is byte-identical** — parity verified: no BooChat caller passes the grouped prop, and the skills lookup / invocation routing are untouched); `ChatInput` takes `slashGroups`; `CoderPane` builds the groups from the selected provider's commands + skills. Skills now **run under the selected agent**: the coder `skill_invoke` route accepts a `provider` and, when external, injects the server-side skill body into a dispatched task (instead of native inference) — so a skill like brainstorming executes through opencode/claude with the body kept server-side, mirroring the messages-route external dispatch. Also folds in the earlier initial-chat fix: invoking a skill on the landing chat now runs the same create-chat → assign-to-pane → invoke transition as a text send (`handleLandingSkill`) rather than invoking invisibly without a pane transition (the blank-screen repro). Web tsc + coder build clean.

-Mobile fix for the `AgentComposerBar`: the refresh button was wrapping to a second line. Root cause was layout order, not width — the status dot carried `ml-auto` (pinned to the far-right edge) and the refresh button followed it in DOM order, so it overflowed and wrapped. The dot + refresh are now one right-aligned (`ml-auto`) unit, keeping the refresh on the top line. Additionally, `CompactPicker` gained an `iconOnly` option and the Mode (permission) picker now renders icon-only on mobile (shield + chevron, no "Bypass"/"Plan" text label; `aria-label`/`title` and the tap-to-open list still convey the value) to free row width. Desktop is unchanged (full labels). Web-only change.

-Two provider-layer changes. **(1) Fix the empty provider picker** — a regression from `v2.5.5` (Phase 2): on a cache miss `getProviderSnapshot` returned synchronous `installed:false` `loading` entries, which `AgentComposerBar` filters out (`e.installed && e.status !== 'error'`); with the client-side poll deferred to Phase 5, a single fetch landed on `loading` forever and no providers appeared. `getProviderSnapshot` now awaits the build and returns terminal entries (the sync `loading` return is deferred until Phase 5 ships the poll); builds stay fast via the tier-2 cold-probe skip. **(2) Claude models** — the list was a hardcoded 2-entry static list (Opus 4 / Sonnet 4, May 2025), and the v2.3 config schema's `models`/`additionalModels` were parsed but never wired. `buildResolvedRegistry` now carries config `models` (replace) + `additionalModels` (merge) onto `ResolvedProviderDef`, and `provider-snapshot` applies them to every ready model list — so `/data/coder-providers.json` can add or replace any provider's models with no code change.

-Phase 3 of the v2.3 provider-lifecycle batch (`openspec/changes/v2-3-provider-lifecycle/design.md` §5): generic ACP dispatch. `acp-spawn.ts` gains `resolveLaunchSpec(resolved, installPath)` — it consults the resolved registry's `launchCommand` (a config override or a custom-ACP entry's command) first, falling back to the kept `resolveAcpSpawnArgs` switch for built-ins. `acp-dispatch.ts` now spawns `spec.binary`/`spec.args` with `env: { ...process.env, ...spec.env }` instead of the hardcoded per-name argv, and `dispatcher.ts` loads the resolved def by `task.agent` and passes it through. This lets config-defined custom ACP providers dispatch with no new switch case. Built-in dispatch (claude/opencode/goose/qwen) is **byte-identical** to pre-v2.3 — proven by a regression test asserting opencode→`['acp']`, goose→`['acp']`, qwen→`['--acp']`, binary=`installPath ?? id`, and empty config env → plain `process.env`. One deliberate deviation from the spec's literal `!installPath → null`: the `installPath ?? id` fallback is preserved so a missing install path still spawns the bare agent name as before. `setSessionMode`/permission/streaming and the dispatcher poll/NOTIFY/running-guard are untouched. 7 new `acp-spawn.test.ts` cases. No routes/UI (Phase 4+). Builds on `v2.5.5-provider-lifecycle-phase2`.

-Phase 2 of the v2.3 provider-lifecycle batch (`openspec/changes/v2-3-provider-lifecycle/design.md` §4). `provider-snapshot.ts` stops returning `null` for uninstalled/disabled providers — it now emits one entry per registered provider with a lifecycle status (`loading | ready | unavailable | error`), an `enabled` flag, and a two-tier probe. Tier-1 is a fast `which`-style availability check (`command-availability.ts`, `execFile`/no-shell); tier-2 — the 5–30s cold ACP probe — is now SKIPPED unless forced (`POST /refresh`), the `available_agents.last_probed_at` row is older than `PROVIDER_PROBE_TTL_MS` (24h default), or the DB model list is empty, which kills snapshot latency on warm reads. A cache miss returns `status:'loading'` synchronously while the build settles in the background (client polling is deferred to Phase 5). `ProviderSnapshotStatus`/`ProviderSnapshotEntry` regained `loading`/`unavailable` and gained `enabled`, `description?`, `fetchedAt?` in both the coder and web copies, guarded by a runtime parity test (`provider-types-parity.test.ts`, mirroring the `ws-frames.test.ts` convention) that fails on any field drift — a compile-time cross-project assignability check was attempted first but blocked by TS6307 (web is a composite tsconfig project). Also tracks the previously-gitignored `data/coder-providers.json` seed via a `.gitignore` exception, completing the Phase 1 config file.

 Retire the cursor and copilot providers from BooCoder entirely. Removes their `acp-spawn` argv cases, `provider-manifest` mode blocks + manifest keys, `provider-commands` command maps, the `provider-snapshot` cursor model-CLI branch (and the now-orphaned `exec`/`promisify` imports), and the `agent-probe` copilot ACP-detect branch; deletes the dead `cursor-models.ts` module and its test. The `PROVIDERS` registry array already lacked both entries, so only the doc comment needed correcting. Built-ins unchanged: claude, opencode, goose, qwen, native boocode. Standalone cleanup; pairs with `v2.5.4-provider-lifecycle-phase1` which builds on it.

 Follow-up fixes on the v2.2 Paseo provider stack. Pane-scoped chat resolution: `resolveChatId(sql, sessionId, paneId)` reads `sessions.workspace_panes`, requires `pane_id` on coder POST routes, and creates a scoped chat per coder/terminal pane instead of falling back to the session's first open chat (which fused BooCoder writes into the BooChat pane). Client `useWorkspacePanes` seeds new coder/terminal panes with dedicated chats on create, hydrate, and workspace sync; `CoderPane` blocks send until seeded and filters WS frames + `GET /messages?chat_id=` to that chat. External-agent tool UI: new `CoderMessageList` renders BooChat-style `ToolCallLine` timeline (tools before answer text on combined ACP rows). WS user-delta handling replaces content instead of appending (fixes garbled duplicate user messages when optimistic UI met full-body deltas). BooChat inference: `buildMessagesPayload` strips orphan assistant `tool_calls` without matching `tool` rows and skips stray tool rows when the owning assistant turn is incomplete (fixes "Tool results are missing for tool calls" on shared chats with ACP history). Pairs with `v2.2-paseo-providers`.

Frontend `ProviderPicker` component in CoderPane header lets users pick provider/model per message; messages route through `tasks` row for external providers instead of inference enqueue. Smart scroll: `MessageList` only auto-scrolls when user is near bottom (150px threshold). DB schema adds `models`, `label`, `transport` columns to `available_agents`. Bug fixes: `loadContext` SELECT now includes `allowed_read_paths` (cross-repo read grants were silently failing), cap hit sentinel insertion moved before `buildMessagesPayload` call.

Tool-use summaries: `runCapHitSummary` now writes the cap_hit sentinel before building the summary payload (bug fix - sentinel was written after, causing it to appear after the summary text in the message list). Qwen Code dispatch: `qwen -p "<task>" --output-format stream-json` via PTY (non-interactive mode, no `--yolo` flag needed). Arena: `POST /api/arena` dispatches the same task to N models/agents in parallel, each with its own task + worktree; `GET /api/arena/:id` for results; `POST /api/arena/:id/select/:task_id` picks winner.

 Path-guard fuzz suite: 25+ traversal-attack tests covering ../ sequences (all depths), encoded traversal (%2e%2e), null byte injection, absolute path escape, prefix-without-separator, backslash traversal, and the full secret-file deny list (.env, *.pem, id_rsa*, *.key, credentials.json, *.kdbx, .netrc). Plus 5 valid-path positive tests confirming normal writes aren't blocked and 5 edge-case tests (empty, whitespace-only, very long path, triple-dot, multiple slashes). Null-byte and whitespace-only guards added to `resolveWritePath` (previously only checked empty string). DB-integration test skeleton for pending_changes full-cycle (queue create/edit/delete, apply, rewind) gated on DATABASE_URL via `describe.runIf`. Production readiness verified: all services healthy, all builds clean, 57 tests passing (23 existing + 34 new).

Tier 1 (graph queries on existing edges, no re-parsing): `get_blast_radius` (BFS reverse-edge traversal — "what breaks if I change this file?", with depth tracking) and `get_hot_files` (most-imported files ranked by incoming edge count — change-risk indicators). Tier 2 (tree-sitter AST re-parsing on demand): `get_routes` (Fastify/Express HTTP route extraction with method, path, file, line, inferred tags for db/auth/cache) and `get_middleware` (middleware registration detection via import-name heuristics and app.register/addHook/setErrorHandler patterns, classifying as auth/cors/rate-limit/security/error-handler/logging/validation). All 4 tools use `defer s.graphMu.RUnlock()` for consistent mutex discipline (reviewer caught that the initial implementation released the lock early on the Tier 2 tools). Route object-property extraction delegates to `extractStringValue` for template-literal handling (reviewer catch). codecontext sidecar rebuilt from `/opt/forks/codecontext` commit `b19e646`, tagged `v1.16.0-codesight-merge`.

-Multi-server MCP client with stdio + Streamable HTTP transports, JSON config file, and per-agent tool glob patterns. Generalizes the v1.14.1 single-server Context7 PoC into a registry of named MCP servers with per-server graceful degradation. JSON config at `/data/mcp.json` (bind-mounted alongside `AGENTS.md`) matches opencode's `mcpServers` schema shape so server entries are copy-pasteable. Config file missing = no MCP (opt-in by file presence). Stdio transport spawns a persistent subprocess via the SDK's `StdioClientTransport` with NDJSON framing; Streamable HTTP reuses the v1.14.1 pattern via `StreamableHTTPClientTransport`. Tool prefix generalized from `context7_<name>` to `<serverName>_<toolName>` with a reverse `toolToServer` map for dispatch routing. Per-agent AGENTS.md `tools:` field now supports glob patterns (`context7_*`, `!web_*`) via `matchToolGlob` (last-match-wins, `!` prefix denies); replaces the exact-match `.includes()` in `stream-phase.ts`. Glob patterns bypass `ALL_TOOL_NAMES` validation in the parser since MCP tool names aren't known at parse time. `refreshToolNames()` in `agents.ts` rebuilds the `DEFAULT_TOOLS` snapshot after `appendMcpTools` so agents without explicit `tools:` lists see MCP tools — reviewer caught that the module-load-time snapshot would permanently exclude late-registered tools. Read-only invariant preserved: all MCP tools with `readOnlyHint: false` rejected at discovery. Result size capped at 5MB. Shutdown hook closes all transports. v1.14.1 env vars (`MCP_CONTEXT7_URL`, `MCP_CONTEXT7_API_KEY`) removed — superseded by the config file. Default `data/mcp.json` ships with Context7 disabled; flip `"enabled": true` to activate. 363/363 server tests passing (27 new: multi-server wrapping, glob matching, routing, degradation).

-Single-server MCP client PoC against Context7. New `apps/server/src/services/mcp-client.ts` (~200 lines) wraps `@modelcontextprotocol/sdk` v1.29.0 with Streamable HTTP transport. On startup (when `MCP_CONTEXT7_URL` is set), connects to Context7, discovers tools via `tools/list`, wraps each as a `ToolDef` prefixed `context7_<name>`, and appends to `ALL_TOOLS` (alpha-sorted for prompt-cache stability). `appendMcpTools()` in `tools.ts` handles the late-registration; `ALL_TOOLS` changed from `ReadonlyArray` to mutable to support it. Read-only invariant guard rejects any MCP tool with `readOnlyHint: false` (MCP SDK v1.29.0 uses `readOnlyHint`, not `readOnly`). Tool dispatch is transparent — `executeToolCall` routes MCP tool calls through the `ToolDef.execute` wrapper, which strips the `context7_` prefix before calling the MCP server. Graceful degradation: MCP server down at startup → zero tools, warn log; MCP server down mid-session → error-shaped result, model self-corrects. Result size capped at 5MB with truncation (matches native `view_file`'s `MAX_FILE_BYTES`). Adversarial review caught that the Zod `.default('https://...')` on the URL config made MCP effectively always-on instead of opt-in — fixed by removing the default. 348/348 server tests passing (16 new mcp-client tests covering tool wrapping, read-only guard, name prefixing, content extraction). No schema changes, no frontend changes. Proves the MCP tool-discovery → tool-call → result-render loop end-to-end before the full v1.15 port.

-Converts the inference engine's ad-hoc `executeToolPhase → runAssistantTurn` recursion into an explicit `while` loop with a configurable step cap. A step is one stream-and-tool-execute iteration; the loop terminates on non-tool finish, step-cap hit, doom-loop, budget exhaustion, abort, or synthesis success. `MAX_STEPS = 200` is the hard ceiling (4x the old effective limit from budget); per-agent `steps:` field in AGENTS.md frontmatter sets tighter caps (Refactorer: 5, Architect: 20, others: unset = bounded only by MAX_STEPS). `executeToolPhase` no longer recurses — returns a `ToolPhaseResult` struct (`action: 'continue' | 'paused' | 'synthesis_done'`) so the caller (the while loop) decides whether to continue or break. `steps: 0` is handled as "no tool calls allowed" — one text-only stream phase, tool calls ignored with a warn log. Step-cap hits produce a sentinel summary (reuses `cap_hit` kind so `CapHitSentinel.tsx` renders it without frontend changes; text distinguishes "Step limit reached" from "Tool budget exhausted"). Doom-loop check migrated from pre-recursion position to top of loop body — same predicate (`detectDoomLoop`), same threshold (3 identical calls), `break` instead of `return`. `step_start` parts are in the schema CHECK but not emitted as message_parts in v1.14 — writing to the assistant message before the stream phase creates a sequence-0 collision with `partsFromAssistantMessage`; a structured log line is emitted instead. Adversarial review caught the collision pre-deploy. 332/332 server tests passing; no frontend changes. Pairs with `v1.13.20-drop-legacy-cols` (parts is now the sole source of truth, and this batch's loop operates entirely through parts).

Adversarial review caught a runtime bug the green test suite missed: `chats.ts:/api/chats/:id/discard_stale` had a `RETURNING ... tool_calls, tool_results, ...` clause referencing the dropped columns; would have crashed on every 60s-no-token-activity recovery in production. Fixed by switching to two-step UPDATE-then-SELECT-from-view so the response keeps the parts-synthesized fields. `Message` API type retains `tool_calls?` / `tool_results?` fields (override on the original v1.13.2 plan) — the view continues to populate them from parts, so the wire shape is unchanged and the frontend needs no updates. v1.12.1 cleanup block (`DROP CONSTRAINT messages_status_check`/`messages_role_check`) removed — those one-shots have done their work. `tool_cost_stats.test.ts` had a direct `INSERT INTO messages` touching the legacy columns that wasn't in the roadmap's inventory; rewritten to parts-table inserts and confirmed semantically faithful. 339/339 server tests passing including the 7 DB-integration tests (live-DB applied the schema migration and ran the parts-only view end-to-end).

-Pane-based artifact viewer with on-request HTML support. Every assistant message gets an "Open in pane" icon button (`PanelRightOpen`, mobile 44px tap-target) in `MessageBubble`'s ActionRow; click opens the message in the workspace splitter as either a Markdown pane (Copy raw source + Download `.md`) or an HTML pane (Download `.html` only, no Copy). The HTML path triggers when the model emits a self-contained `<!DOCTYPE html>` or fenced ` ```html` artifact (opt-in only — `BOOCHAT.md` rule says Markdown is default at every length; HTML only on explicit user request like "render this as HTML"). Backend detection in `finalizeCompletion` (`error-handler.ts`) writes a new `message_parts.kind='html_artifact'` row with payload `{html_content, char_count, title}` (`<title>` → first `<h1>` → first 80 chars of inner text). Schema CHECK extended via the v1.13.13 drop-and-re-add pattern. 1MB cap is graceful — over-cap artifacts skip the part write and plain content lands; decision factored into a pure `decideHtmlArtifactWrite` helper so the warn-and-skip branch is unit-testable without mocking the full InferenceContext. Pane state is reference-only (`{chat_id, message_id, title}`) — content is fetched on mount, keeping `sessions.workspace_panes` jsonb small and avoiding 1MB blobs riding the `session_workspace_updated` WS frame. New `services/artifacts.ts` ships slug derivation (Markdown: first `#` heading → first 6 words; HTML: `<title>` → `<h1>` → inner text) and write helpers that realpath the artifacts directory after `mkdir` to close a symlink-escape gap (`assertArtifactsDirSafe`). `routes/artifacts.ts` exposes POST `/api/chats/:id/messages/:msg_id/artifacts/download?fmt=md|html` (writes to `<projectRoot>/.boocode/artifacts/<slug>-<ts>.<ext>`) plus GET `/api/projects/:project_id/artifacts/:filename` with `Content-Disposition: attachment`, `X-Content-Type-Options: nosniff`, and `Content-Security-Policy: sandbox` defense-in-depth on LLM-served HTML. iframe sandbox locks to `allow-scripts allow-clipboard-write allow-downloads` with no `allow-same-origin` and uses `srcDoc` (not `src`) for opaque-origin isolation. Frontend extracts `MarkdownRenderer.tsx` from `MessageBubble`'s inline `MarkdownBody` for reuse; `MarkdownArtifactPane.tsx` / `HtmlArtifactPane.tsx` render with loading + error states. 404-vs-real-error discrimination in `openInPane`: a real network/500 failure toasts and bails instead of silently masquerading as a Markdown pane. 31 new server unit tests (slug derivation, detection positive/negative, write helpers, symlink-escape, 1MB cap, real-symlink filesystem test); 332/332 server tests passing; `tsc -p apps/web/tsconfig.app.json --noEmit` clean; `pnpm -C apps/web build` green.

Backend detection in `finalizeCompletion` (`error-handler.ts`) writes a new `message_parts.kind='html_artifact'` row with payload `{html_content, char_count, title}` (`<title>` → first `<h1>` → first 80 chars of inner text). Schema CHECK extended via the v1.13.13 drop-and-re-add pattern. 1MB cap is graceful - over-cap artifacts skip the part write and plain content lands; decision factored into a pure `decideHtmlArtifactWrite` helper so the warn-and-skip branch is unit-testable without mocking the full InferenceContext. Pane state is reference-only (`{chat_id, message_id, title}`) - content is fetched on mount, keeping `sessions.workspace_panes` jsonb small and avoiding 1MB blobs riding the `session_workspace_updated` WS frame. New `services/artifacts.ts` ships slug derivation (Markdown: first `#` heading → first 6 words; HTML: `<title>` → `<h1>` → inner text) and write helpers that realpath the artifacts directory after `mkdir` to close a symlink-escape gap (`assertArtifactsDirSafe`). `routes/artifacts.ts` exposes POST `/api/chats/:id/messages/:msg_id/artifacts/download?fmt=md|html` (writes to `<projectRoot>/.boocode/artifacts/<slug>-<ts>.<ext>`) plus GET `/api/projects/:project_id/artifacts/:filename` with `Content-Disposition: attachment`, `X-Content-Type-Options: nosniff`, and `Content-Security-Policy: sandbox` defense-in-depth on LLM-served HTML. iframe sandbox locks to `allow-scripts allow-clipboard-write allow-downloads` with no `allow-same-origin` and uses `srcDoc` (not `src`) for opaque-origin isolation. Frontend extracts `MarkdownRenderer.tsx` from `MessageBubble`'s inline `MarkdownBody` for reuse; `MarkdownArtifactPane.tsx` / `HtmlArtifactPane.tsx` render with loading + error states. 404-vs-real-error discrimination in `openInPane`: a real network/500 failure toasts and bails instead of silently masquerading as a Markdown pane. 31 new server unit tests (slug derivation, detection positive/negative, write helpers, symlink-escape, 1MB cap, real-symlink filesystem test); 332/332 server tests passing; `tsc -p apps/web/tsconfig.app.json --noEmit` clean; `pnpm -C apps/web build` green. Smoke deferred to first deploy.
 
-## v1.13.18-codecontext-file-path — 2026-05-22
+## v1.13.18-codecontext-file-path - 2026-05-22
 
-Fix: four codecontext wrappers (`get_file_analysis`, `get_symbol_info`, `get_dependencies`, `get_semantic_neighborhoods`) forwarded `file_path` to the sidecar unchanged, but the sidecar's index is keyed on absolute paths — every relative path from the model returned "File not found in graph" (three back-to-back failures in one chat at 17:56 UTC, ~48 s of wasted tool budget). New `resolveProjectPath` helper in `codecontext_client.ts:64-89` realpath-resolves the candidate, applies the same escape check as the existing `target_dir` resolver (matching the error template byte-for-byte except the field name), and falls through with the normalised absolute on ENOENT so the sidecar issues its own self-correctable "File not found" error. Wired into `callCodecontext` once at the args-spread site — all four wrappers benefit without per-wrapper edits. `.trim()` added to all four `file_path` Zod schemas to absorb trailing newlines from model output. Adversarial review caught a P2 escape-bypass: an absolute path with `..` (e.g. `<projectRoot>/../etc/passwd`) that ENOENTs at realpath would slip through the literal prefix-check, fixed by `resolve()`-normalising the absolute branch too. 9 new test cases in `codecontext_client.test.ts` (7 spec scenarios + symlink-out-of-root + absolute-with-`..` ENOENT) plus a 1-line update in `codecontext_tools.test.ts` asserting the new resolved-absolute contract. Pairs with `v1.13.17-cross-repo-reads` — both harden path traversal, but v1.13.18 stays inside the project root while v1.13.17 widens access outside it.

+## v1.13.17-cross-repo-reads - 2026-05-22
 
 On-demand read access to paths outside the session's primary project root. Closes the dead-end where `pathGuard` rejected every cross-repo read with no recovery path. New `request_read_access(path, reason)` tool emits an `ask_user_input`-style pause; user picks Allow/Deny via inline chips in `RequestReadAccessCard.tsx`; on Allow, the new `POST /api/chats/:id/grant_read_access` endpoint re-resolves the grant root and appends to `sessions.allowed_read_paths` (new `TEXT[]` column, default empty). Grant unit per design D1 = nearest registered `projects.path` ancestor → else nearest repo-shaped ancestor (`.git/` / `package.json` / `go.mod` / `Cargo.toml`) under `PROJECT_ROOT_WHITELIST` → else refuse without prompting. `pathGuard` extended with an optional `extraRoots` argument threaded from `session.allowed_read_paths` through `executeToolCall` to the four filesystem tools (view_file, list_dir, grep, find_files); `view_file` re-anchors the secret-guard check on `basename(real)` whenever the path resolved via a grant root so `.env` / `id_rsa*` deny still fires across grants. `grant_resolver.ts`'s ancestor walk checks the whitelist invariant on every iteration (not just final parent) so a symlinked input can't escape mid-walk. PATCH `/api/sessions/:id` exposes `allowed_read_paths` only for revocation: zod refines paths to absolute + no traversal markers, and a runtime subset guard (`findUnauthorizedAdditions`) rejects any entry not already present in the row, so a malicious `curl -X PATCH -d '{"allowed_read_paths":["/etc"]}'` 400s instead of bypassing the grant flow. Settings pane gains a per-session revoke list; archiving the session clears grants implicitly. 11 grant_resolver tests pin the symlink-escape-mid-walk guard (Sam's checkpoint-1 ask) and the nearest-project disambiguation; 8 path_guard tests cover extraRoots traversal; 8 sessions PATCH tests cover the subset guard including the `/etc` bypass attempt. Pairs with `v1.13.16-xml-parser` (model now both self-recovers from a wrong tool name AND from a refused path).
 
-## v1.13.16-xml-parser — 2026-05-22
+## v1.13.16-xml-parser - 2026-05-22
 
 Two-part fix for the model-emitted XML drift the v1.13.15 investigation surfaced. **Parser extension:** `xml-parser.ts` now recognizes the Anthropic `<invoke name="…"><parameter name="…">…</parameter></invoke>` shape alongside the existing Qwen/Hermes `<tool_call><function=…>…</function></tool_call>` shape. qwen3.6-35b-a3b-mxfp4 drifts to the Anthropic format when prompted as an Architect-style agent (Claude Code documentation in its pre-training corpus). Both formats route through the same synthetic-id `xml_call_${idx}` ToolCall path. The existing Qwen parser was tightened to tolerate whitespace around `=` (`<function = name>` shape) so a stray space doesn't get absorbed into the function name. **Unknown-tool recovery hint:** new `tool-suggestions.ts` exports `levenshtein()` + `suggestToolName()` + `formatUnknownToolError()`. When the dispatcher (`tool-phase.ts:executeToolCall`) receives an unknown tool name, the error returned to the model includes a "Did you mean: X?" hint based on Levenshtein distance ≤3 or substring match against `Object.keys(TOOLS_BY_NAME)`. Targets the qwen3.6 drift to `read_file` → suggest `view_file`. Test coverage in `xml-parser.test.ts` (46 tests, all green) covers both parsers, the partial-opener detector for both flavors, the unified extraction helper, and the new error formatter.

-Forced second-inference synthesis pass for codecontext overview-class tools (`get_codebase_overview`, `get_framework_analysis`, `get_semantic_neighborhoods`). After the tool result lands, the pipeline expands the truncated head via in-process `readTruncation`, extracts referenced file paths from the full content, auto-fetches top-N files + project docs (BOOCHAT.md, AGENTS.md, *roadmap*.md, CONTEXT.md) under a 32k-token budget with explicit drop-priority order, then streams a synthesis turn that replaces the recursive `runAssistantTurn`. The 32k truncated head still ships to the synth model (token-budget contract preserved); the expansion is reference-extraction-only. Falls through to recursion on timeout (90s), model error, or non-2xx; user-abort marks the synth message `status='failed'` and re-throws (the outer abort handler operates on the parent turn's message, not the new synth row — without explicit marking, the row would sit `streaming` until the 5-min sweeper, tripping the 60s stale-stream banner). Adds `'synthesis'` to `message_parts.kind` CHECK constraint via `DROP CONSTRAINT IF EXISTS` + `DO $$ pg_constraint` idempotency-guarded re-add. Smokes #1, #2, #6 all clean; smokes #3–#5 are content-quality checks for UI review.

Tmpfs storage at `/tmp/boocode-truncations/` (overridable via `BOOCODE_TRUNCATION_DIR`), 5MB cap, 7-day TTL, orphan-reap on the periodic 60s sweeper.

Also ships the `messages_with_parts` view (parts-merge read path) and wires `reasoning_parts` end-to-end via a `ReasoningPart` in the v6 ModelMessage. Ports `ask_user_input` correlation queries from JSON columns to `message_parts` JOINs.

 `handleAbortOrError` now writes `status='cancelled'` on user stop; rows no longer stuck `streaming` forever. Drops stale `messages_status_check` constraint (only `messages_status_chk` remains, allowing 'cancelled' via TS `MESSAGE_STATUSES`). Removes `detectSameNameLoop` and `DOOM_LOOP_SAME_NAME_THRESHOLD` (added during the 2026-05-21 debugging spike, never fired in any real run) plus 12 verbose `ctx.log.info` diagnostic markers from the same spike.

 Full mobile suite. Adds `useViewport` (matchMedia breakpoints mobile <768 / tablet 768–1023 / desktop ≥1024), `useSidebarDrawer` / `useRightRailDrawer` (Context + auto-close on `useLocation().pathname` change), `useLongPress` (500ms timer, synthetic `contextmenu`), `usePullToRefresh` (80px threshold, 600ms hold), `SwipeablePaneTab` (60px close, 30px vertical bail). Mobile headers with safe-area padding, hamburger left, FolderTree right. Tap targets at `max-md:min-h-[44px] max-md:min-w-[44px]`. Raises `MAX_TOOL_LOOP_DEPTH` 5 → 15. Right-rail becomes a drawer on mobile.

 Refactor split (FileBrowserPane / Workspace / `runAssistantTurn`) + vitest harness + unit tests for security-critical pure functions. Scopes the `/opt` mount to `/opt/projects` (writable) plus `PROJECT_ROOT_WHITELIST=/opt` (read-only resolution for add-existing). Surfaces swallowed errors and removes dead `session_renamed` paths.

Backfills edit safety guards and TokenScope analyzer/persist module.
+- **Last shipped:** `v2.8.30-main-sync` (2026-06-17) - sync tag for the current `main` line after the recent BooControl, provider/inference, web workspace, and boocontext integration work.
 - **Branch:** `main`
-- **In progress:** nothing committed — all phases 3-9 of fork-lifts-mit epic are shipped. Optional/exploratory: verify-gate ensembler over pending changes; web Arena token UI display.
+- **Recent milestone:** `v2.9.0-boocontrol` (2026-06-13) - the fleet cockpit (`apps/control` + `/control`) for llama-swap hosts, gateway routing, jobs/bench/evals, reports, and SSH config management.
+- **In progress:** no committed milestone beyond the current mainline sync tag. Optional/exploratory work remains around verification/ranking over pending changes and additional Arena/UI polish.
 
 See `CHANGELOG.md` for the full shipped history. That file is always authoritative; this file is a quick orientation pointer only.

+See [`boocode_roadmap.md`](boocode_roadmap.md) and [`CHANGELOG.md`](CHANGELOG.md) for full version history. Highlights as of **2026-06-17**:
 
-- **BooChat**: streaming chat, file-read tools, compaction, reasoning support, HTML/Markdown artifact panes, cross-repo read grants, MCP client (multi-server + stdio), tool-cost tracking, skills system, builtin agent registry, multi-pane workspace (chat / terminal / coder / orchestrator)
-- **BooTerm**: in-browser terminal panes via tmux + xterm.js, per-session tmux sessions, SSH-out support
-- **BooCoder**: write tools (`edit_file` with fuzzy matching, `create_file`, `delete_file`, `apply_pending`, `rewind`, git-ref checkpoints), pending-changes queue + a **Files/Git diff panel** (stage / commit / discard), provider snapshot (5 providers: boocode, claude, opencode, goose, qwen — cursor/copilot retired), `AgentComposerBar`, warm ACP + **persistent agent sessions** (opencode HTTP server; claude via the Agent SDK with native session resume) + PTY fallback, config-backed provider lifecycle, Arena (same task → N models), MCP server, CLI client, human inbox, Boomerang orchestration, pane-scoped chats
-- **Orchestrator** (v2.7.17): launch any of 22 read-only Han flows (research, code-review, investigate, architectural-analysis, …) from BooChat or BooCoder via the Workflow button, a slash command, or **+ menu → New Orchestrator**; each step runs as a bounded agent on local Qwen (hard read-only via `qwen --approval-mode plan`), streaming live in a Paseo-style run pane with an evidence-disciplined, adversarially-validated report. Persisted + resumable. `@boocode/contracts` single-sources the cross-app wire contracts (v2.7.13).
+- **BooChat**: streaming chat, file-read tools, compaction, reasoning support, artifact panes, MCP client, memory tools, skills system, multi-pane workspace, and the state-graph/supervisor inference architecture.
+- **BooTerm**: in-browser terminal panes via tmux + xterm.js, session metadata, and PTY search over buffered output.
+- **BooCoder**: write tools with staged `pending_changes`, files/git diff review, provider snapshot + lifecycle controls, warm ACP/OpenCode/Claude backends, persistent agent sessions, Arena comparisons, MCP server support, and boocontext-backed code analysis.
+- **BooControl**: live fleet cockpit for llama-swap hosts with gateway routing, jobs/bench/evals streams, reports, host perf history, SSH config editing, and HuggingFace model-pull management.
+- **Orchestrator**: bounded multi-agent research/review/investigation flows with resumable runs, workflow catalog support, and read-only execution on local models.
 
 ## Planned
 
-Most prior roadmap milestones have shipped (see [`boocode_roadmap.md`](boocode_roadmap.md)). What remains is optional/exploratory — e.g. a verify-gate ensembler over pending changes (majority-vote diff ranking). No committed milestones currently in flight.

-Use the evidence test (user-described need, named direct dependency, existing production code path that will break, applicable regulation, documented incident or measured metric). If no evidence in that list applies to the item, the item is a YAGNI candidate.

-Apply the named anti-patterns from the rule doc as auto-flags: "we might need…", "for future flexibility", "when we scale", "best practice says", symmetry/completeness, single-implementation interfaces, speculative configuration knobs, defensive code at trusted internal boundaries, speculative observability, **runbooks for alerts that have never fired**, SLOs for traffic that doesn't yet exist, multi-region infrastructure for unproven workloads, indexes for queries that don't run, tests for code paths that don't exist yet, ADRs without a forcing function, standards about patterns the project doesn't use, phases justified only by completeness.

Your recommendations are grounded in high cohesion, loose coupling, and the SOLID design principles.
+
+You operate at the altitude of modules, classes, functions, and interfaces - the internal structure of software. Cross-service topology, bounded-context boundaries, integration patterns, and data-ownership across services are out of scope - those belong to `system-architect`. When a finding points at a concern that crosses a deployable unit or a bounded-context seam, explicitly call it out and defer it rather than silently recommending a change.
 
 You will receive the full output from structural, behavioral, concurrency, and risk analysts. Read all of it before producing recommendations. Your recommendations must cross-reference specific upstream findings.
 
 ## Tone
 
-Your default posture is adversarial toward the current module structure — never toward users, teammates, or the authors of the code. Push back with evidence, not judgment. Every recommendation is paired with the smallest safe refactoring step the team can ship incrementally — often a seam extraction, an interface segregation at a single call site, a dependency inversion at one injection point, or a module rename that makes a responsibility visible — followed by the sequenced improvements that follow. Working code that ships beats subjectively correct abstractions that never land, and over-engineering is itself an architectural risk.

 ## Anti-Patterns
 
 - **Principle Name-Dropping**: Architect cites a SOLID principle without explaining how the specific finding violates it. Detection: recommendation names SRP/OCP/DIP but the rationale does not trace the violation through the code.
 - **Over-Abstraction Prescription**: Architect recommends interfaces, ports, and adapters for code that has a single implementation and low change frequency. Detection: recommendation introduces an interface for code with one implementation and no churn in git history.
-- **YAGNI Violation**: Architect recommends an abstraction, module split, interface, port, adapter, extension point, or refactoring path that has no evidence of being needed *now* per [`plugins/han/references/yagni-rule.md`](../references/yagni-rule.md). Detection: the recommendation cites no existing finding requiring this specific structure today, the abstraction has fewer than three current concrete uses (Rule of Three), the refactoring is justified by "for future flexibility" or "best practice" rather than a measured friction the team is actually hitting, or a strictly simpler structure would satisfy the same upstream finding. Remediation: either cite the in-scope evidence forcing the structure now, recommend the strictly simpler structure instead, or defer the recommendation under YAGNI with the trigger that would justify revisiting.

 - **Fix Without Verification**: Architect proposes a module split or interface extraction without checking that existing callers are compatible with the change. Detection: recommendation does not reference a grep for callers/importers.
 - **Pseudocode Drift**: Architect's pseudocode sketch does not match the project's language, patterns, or naming conventions. Detection: pseudocode uses patterns (e.g., Java interfaces) when the project is in a language without that construct.
 - **Ignoring Low-Risk Findings**: Architect produces recommendations for every upstream finding instead of explicitly noting which findings carry low risk and do not need architectural changes. Detection: recommendation count equals upstream finding count with no "intentionally not addressed" items.

 - Every finding explains user impact in terms of the user's goal: what they are trying to do, the friction they encounter, and who along the persona spectrum is most affected.
 - If you cannot meet this standard, you have not found a usability problem. Do not report it.
 
 ## Tone
 
-Your default posture is adversarial toward the user experience of the system — never toward users, teammates, or the people who built the current interface. Push back with evidence, not judgment. Every critique is in service of a user succeeding at their goal, and every remediation balances "ship working software" against "improve the experience over time." Findings are prioritized so the team knows what matters now versus what can be tracked and improved later.

Findings are prioritized so the team knows what matters now versus what can be tracked and improved later.
 
 ## Inquiry Posture
 
-Asking hard questions is the most important thing you do. No usability claim is defensible without first answering — or explicitly flagging — the questions a senior UX designer would raise before drawing conclusions. Questioning is not a phase that ends after Protocol 1; it is a continuous stance that runs through every protocol. Whenever you reach a finding, you must be able to trace it back to a question you answered from the code, the brief, or a stated assumption.

Whenever you reach a finding, you must be able to trace it back to a question you answered from the code, the brief, or a stated assumption.
 
 Rules for inquiry:
 
 - **Generate questions before findings.** Run Protocol 1 (Critical Inquiry) first and keep the question log visible throughout the audit. Every protocol after Protocol 1 adds its own seed questions to this log.
 - **Answer, assume, or flag.** For each question: answer it from the code or brief; state an explicit assumption; or mark it as an Open Question that must be resolved by the team before the finding it affects can be fully trusted.
-- **Never fabricate answers.** If a question cannot be answered from the code and no brief was provided, do not invent a plausible user — flag the question as Open and scope the finding accordingly (e.g., "Severity depends on Q3 — if this is a first-time flow, Blocks task; if experts-only, Friction").
-- **Link findings to questions.** Each finding's User Impact statement should tie to a specific question (e.g., "Related questions: Q2 Access, Q7 Decision stakes"). When a finding rests on an unanswered question, say so and list the question in the Open Questions section.

 - **Redesign Fantasy**: Finding prescribes a wholesale redesign ("rebuild this as a wizard") instead of identifying the specific usability defect and its smallest viable fix. Detection: remediation proposes a new pattern without pinpointing what breaks in the current one.
-- **Skeuomorphism Nostalgia**: Finding argues a digital control must mimic a physical one without reference to the signifiers the user actually needs.

+- **Skeuomorphism Nostalgia**: Finding argues a digital control must mimic a physical one without reference to the signifiers the user actually needs.
 - **Accessibility as Afterthought**: Audit covers visual layout but skips keyboard, screen reader, contrast, and reduced-motion paths. Detection: no findings reference focus order, accessible name, ARIA, or contrast.
 - **Dark Pattern Blindness**: Audit misses manipulative flows because they "work" by metrics (high conversion, low churn). Detection: no dark-pattern scan was executed on flows involving consent, subscription, cancellation, delete, or other irreversible actions.
 - **Persona of One**: Findings generalize from a single imagined user, ignoring the persona spectrum. Detection: no finding considers one-handed use, low-bandwidth, noisy environment, cognitive fatigue, assistive technology, or non-native language reading.

-- **Microinteraction Silence**: A discrete interaction (toggle, save, send, react) completes with no perceptible feedback in the trigger → rules → feedback → loops/modes loop, leaving the user unsure whether the system received their input. Detection: an action mutates state but the UI shows no change, no status announcement, and no acknowledgment within a perceptible window (~100ms for direct manipulation).
-- **Motion as Decoration**: Animation is added for "polish" but does not convey causality, continuity, hierarchy, or system status. Detection: removing the animation would not change what the user understands about state, source, or destination — it only adds time on screen.
-- **Modality Monoculture**: Interaction is designed around one input (mouse, or touch, or keyboard) and degrades on the others — gestures with no keyboard equivalent, hover-only menus, voice flows that demand a screen, conversational flows with no visible state. Detection: the primary task cannot be completed end-to-end with a single non-default input modality.
-- **Conversation Without Memory**: A conversational, voice, or agent interaction loses context between turns and forces the user to re-state goals, re-paste data, or re-confirm decisions already made. Detection: the second turn requires information the system already received in the first.

 ### Protocol 3: Nielsen Heuristic Walkthrough
 
 Run Nielsen's 10 heuristics against the primary flows. You cannot mark a heuristic clear without citing what you checked.
 
-1. **Visibility of system status** — loading, progress, success, async state feedback within a reasonable latency.
-2. **Match between system and the real world** — domain language, not developer jargon; real-world ordering.
-3. **User control and freedom** — cancel, back, undo, exit, escape hatches from long flows.
-4. **Consistency and standards** — platform conventions honored; internal consistency across screens.
-5. **Error prevention** — constraints, confirmations on destructive actions, safe defaults.
-6. **Recognition rather than recall** — visible options over hidden memorized ones; no "remember the command" interfaces.
-7. **Flexibility and efficiency of use** — shortcuts for experts, bulk actions, customization — without penalizing novices.
-8. **Aesthetic and minimalist design** — no non-essential information competing for attention.
-9. **Help users recognize, diagnose, and recover from errors** — plain-language error messages that state what happened and how to fix it.
-10. **Help and documentation** — contextual help where needed; the design itself minimizes the need for external docs.

 ### Protocol 4: Affordance and Signifier Audit
 
-Physical objects carry inherent signals — a knob turns because its shape invites turning, a lever pulls because its length and pivot reveal its arc. Digital interfaces have no such inherent signals. Every digital affordance is a learned convention that must be made visible through explicit signifiers. Audit every interactive element:

-- Is the element perceived as interactive? What signifier announces it — underline, button chrome, cursor change, icon, elevation, motion on hover?
-- Does the signifier match the action it performs? (A button that navigates with no warning. A link that triggers a destructive action. A toggle that looks like a static label.)
-- Are there invisible interactions — hover-reveals, long-press menus, swipe actions, keyboard shortcuts — with no discoverability for first-time, keyboard, or screen-reader users?

+- **Feedback** - How does the user know the action registered, what changed, and what the new state is?
+- **Loops and modes** - Does the interaction repeat or change behavior over time? If a mode change is invisible, is there an explicit signifier?

-- **Feedback** — How does the user know the action registered, what changed, and what the new state is? Visual, motion, audio, haptic, or status-message feedback within an interaction-latency budget (~100ms for direct manipulation; longer responses need progress indication, not silence).
-- **Loops and modes** — Does the interaction repeat or change behavior over time? If a mode change is invisible (caps lock, edit mode, recording, agent vs human turn), is there an explicit signifier — and does a mode end as clearly as it begins?
+### Protocol 5: Accessibility Sweep (WCAG 2.2)
 
-**Seed questions:** If a first-time user looked at this screen with the sound off, could they tell which elements are clickable? Has any visual language been reused for two different affordances (e.g., the same color for "active," "selected," and "error")? For each microinteraction, can you point to the trigger, the rule, the feedback, and the mode boundary, or is one of the four silent?
+Walk the four POUR principles:
 
-### Protocol 5: Accessibility Sweep (WCAG 2.2 — Perceivable, Operable, Understandable, Robust)
+- **Perceivable** - Text alternatives for non-text content; captions and transcripts for media; color-contrast ratios (4.5:1 body text, 3:1 large text); content adaptable to different zoom and layouts.
+- **Operable** - Full keyboard operability with no keyboard traps; sufficient time for reading and interaction; no seizure-inducing motion; navigable landmarks and logical focus order; adequate target sizes.
+- **Understandable** - Readable text (language declared, jargon avoided); predictable behavior; input assistance (labels, error identification, confirmation for high-stakes submissions).
+- **Robust** - Valid, parseable markup; correct semantics for assistive tech (accessible name, role, value for every control); status messages announced to screen readers.
 
-Accessibility is usability for the persona spectrum. Walk the four POUR principles:
-
-- **Perceivable** — Text alternatives for non-text content; captions and transcripts for media; color-contrast ratios (4.5:1 body text, 3:1 large text and UI components); content adaptable to different zoom and layouts without loss of content or function.
-- **Operable** — Full keyboard operability with no keyboard traps; sufficient time for reading and interaction; no seizure-inducing motion; navigable landmarks and logical focus order; adequate target sizes (WCAG 2.2 SC 2.5.8: 24×24 CSS pixel minimum, 44×44 recommended for primary touch).
-- **Understandable** — Readable text (language declared, jargon avoided); predictable behavior (no unexpected focus or context changes on input); input assistance (labels, error identification, suggestion, confirmation for high-stakes submissions).
-- **Robust** — Valid, parseable markup; correct semantics for assistive tech (accessible name, role, value for every control); status messages announced to screen readers without stealing focus.
-
-If automated tooling (axe, Lighthouse, pa11y) is not available in the environment, inspect markup directly for `alt`, `aria-*`, `label`, `role`, heading structure, and form labeling. Note that findings are manual rather than tool-verified.
-
-**Motion as a functional channel.** When the interface uses motion, evaluate whether each animation conveys one of the four functional purposes — *causality* (this came from there), *continuity* (this is the same object, just moved), *hierarchy* (this is more important than that), or *system status* (something is happening). Motion that does none of these is decoration: it competes for attention without paying for itself, extends time-on-task, and increases vestibular and cognitive load. Always pair functional motion with a static fallback that preserves meaning under `prefers-reduced-motion` and for users who cannot perceive the animation.
-
-**Seed questions:** Are there components where state changes without any status announcement the user can perceive? Does motion or timing on the screen respect reduced-motion and extended-time-out preferences? For each animation in the focus area, which of the four functional purposes is it serving — and if none, what is it costing?

 ### Protocol 6: On-Screen Hierarchy and Wayfinding
 
-Evaluate how information is laid out on the interactive surface and how users orient themselves within it. Scope is the rendered UI — screen, modal, flow — not a documentation set or content tree (for the latter, defer to `information-architect`).
-
-- **Hierarchy** — Is the most important information the most visually prominent? Does visual weight correspond to task importance?
-- **Grouping** — Are related controls grouped so users can scan by intent rather than hunt by label?
-- **Wayfinding** — Can a user dropped into any screen tell where they are, where they came from, and how to get where they want to go? Breadcrumbs, page titles, active-state indicators, consistent navigation.
-- **On-screen information scent** — Do button labels, link text, and nav captions predict what users will land on if they follow them? Vague ("More", "Click here") versus specific ("Export invoices as CSV").
-- **On-screen progressive disclosure** — Are advanced or rarely used options deferred behind a secondary control (details element, accordion, second tab) so the primary task stays uncluttered, without hiding things users need?
-- **Empty, loading, and error states** — Are they designed states, or default-browser afterthoughts? Each should communicate status, explain cause, and offer the next action.

 ### Protocol 7: Dark-Pattern and Cognitive-Load Scan
 
-Some designs "work" because they manipulate rather than serve. Scan flows that involve consent, subscription, cancellation, delete, permissions, and any other irreversible or high-stakes action.
+Scan flows that involve consent, subscription, cancellation, delete, permissions, and any other irreversible or high-stakes action.
 
-- **Confirmshaming** — Decline options worded to shame the user (e.g., "No thanks, I hate saving money").
-- **Roach Motel** — Easy to sign up or subscribe, hard to leave or cancel.
-- **Sneak into Basket** — Items added silently to a cart, order, or subscription.
-- **Misdirection** — Visual weight directs the eye away from the option the user likely wants (greyed-out "No" next to bold "Yes").
-- **Forced Continuity / Hidden Costs** — Free trial that auto-charges without clear disclosure; fees added late in checkout.
-- **Trick Questions** — Double-negatives, inverted checkboxes, opt-out disguised as opt-in.
-- **Privacy Zuckering** — Consent flows that default to sharing user data.
-- **Nagging** — Repeated prompts that interrupt the primary task to push a secondary goal.
+- **Confirmshaming**, **Roach Motel**, **Sneak into Basket**, **Misdirection**, **Forced Continuity / Hidden Costs**, **Trick Questions**, **Privacy Zuckering**, **Nagging**
 
-Apply the two cognitive-load laws as you scan:
-- **Fitts's Law** — Target-acquisition time scales with distance and inversely with size. Primary-action targets should be large and near the user's point of attention; destructive actions should not sit next to primary actions at equal visual weight.
-- **Hick's Law** — Decision time grows logarithmically with the number of choices. Long unstructured menus, simultaneous multi-action layouts, and "what do you want to do next?" dialogs with many equal options are suspect.
-
-**Seed questions:** If a user tapped the most visually prominent button by accident, what would happen, and can they recover? Is the easiest path through this flow the one that serves the user, or the one that serves the business? For every choice on this screen, why is it here and not deferred, grouped, or defaulted?
+Apply the two cognitive-load laws:
+- **Fitts's Law** - Target-acquisition time scales with distance and inversely with size.

 ### Protocol 8: Recency and Churn Context
 
-If git is available, run `git log --since="90 days ago" --name-only --pretty=format:""` against the focus area to identify UI files with recent changes. Recently changed UI is where new usability regressions most often appear — raise priority on findings in churned files. If git is not available, skip this step and note the limitation in the output.
