v1.12.1: stop-handler writes terminal status + constraint cleanup + dead code removal

- handleAbortOrError now writes status='cancelled' on user stop; rows
  no longer stuck 'streaming' forever
- Drop stale messages_status_check constraint (only messages_status_chk
  remains, allowing 'cancelled' via TS MESSAGE_STATUSES)
- Remove detectSameNameLoop and DOOM_LOOP_SAME_NAME_THRESHOLD (added
  during 2026-05-21 debugging spike, never fired in any real run,
  existing detectDoomLoop covers actual failure modes)
- Remove 12 ctx.log.info diagnostic markers added during the same
  spike (verbose for production)
- Bundles workspace pane sync + status indicator overhaul +
  startup hung-row sweep landed earlier in v1.12.1 work

+- **`services/inference.ts`** — Streams LLM responses, executes tool loops (max depth 15, see `MAX_TOOL_LOOP_DEPTH`), flushes to DB every 500ms. Publishes `InferenceFrame` events through the broker. **`TurnArgs`** is the per-turn state envelope threaded through the `executeToolPhase → runAssistantTurn` recursion (`toolsUsed`, `recentToolCalls`, `assistantMessageId`, `signal`); reset to defaults in `runInference` at the user-message boundary. Cap-hit (`toolsUsed >= budget`) and doom-loop (`detectDoomLoop(recentToolCalls)`) checks both read from this envelope. Add new per-turn state here, not in module-level closures.
 - **`services/broker.ts`** — In-memory pub/sub with two channel types: per-session (message streaming) and per-user (sidebar updates). No persistence; clients reconnect on restart.
-- **`services/tools.ts`** — Four read-only file tools exposed as OpenAI function-calling schemas. All file access goes through `path_guard.ts` which resolves against project root.
+- **`services/tools.ts`** — Tool registry (`ALL_TOOLS`, `READ_ONLY_TOOL_NAMES`, `TOOLS_BY_NAME`). Filesystem tools (view_file/list_dir/grep/find_files) go through three guard layers: `path_guard.ts` (workspace scope), `secret_guard.ts` (filename deny list), `url_guard.ts` (SSRF/private-IP block for web_fetch). v1.11.8+ web tools (`web_search`, `web_fetch`) are opt-in per chat via `session.web_search_enabled` (resolved with `project.default_web_search_enabled` fallback) and filtered out of the LLM's tool schema when false.
+- **`services/compaction.ts`** + **`services/model-context.ts`** — v1.11.0 anchored rolling summary (single `summary=true` assistant row per chat, supersedes itself on each compaction). Triggered when `chats.needs_compaction` is set after an inference turn exceeds `usable(ctx_max) = ctx_max - 20k`. **`ctx_max` comes from `model-context.getModelContext()` which fetches `${LLAMA_SWAP_URL}/upstream/<model>/props`** — NOT from `parsed.timings.n_ctx` (the stream completion's `timings` doesn't carry n_ctx; that read was dead code until v1.11.3 ripped it out).
 - **`services/file_ops.ts`** — Shared file operation implementations used by both inference tools and HTTP routes.
 - **`services/auto_name.ts`** — Non-streaming LLM call to generate 4-word session titles after first assistant reply.

 - `vite.config.ts` proxy entries are order-sensitive: more-specific prefixes (`/api/term`, `/ws/term`) must come BEFORE `/api`.
 - Mobile pane URL sync (`Session.tsx`): the `?pane=<id>` effect resets `activePaneIdx` whenever `panes` changes. New-pane creation on mobile must push `?pane=` atomically — `addPaneAndSwitch` is the wrapper that does this. `addSplitPane` returns the new pane id for callers.
 - xterm.js v5 uses canvas rendering — browser doesn't see xterm's selection; the native right-click menu has no working Copy for terminal text. App keybindings (`Cmd/Ctrl-C`, `Cmd/Ctrl-Shift-C`) are the path.
+- **New tools** live in their own `services/<name>.ts` file (see `web_search.ts`, `web_fetch.ts`) — exports a pure `executeFoo(input, ...deps)` for direct test access plus a `ToolDef` wrapper that `loadConfig()`s its real dependencies. Register the ToolDef in `tools.ts` `ALL_TOOLS` (and `READ_ONLY_TOOL_NAMES` if applicable). Inject `fetcher: typeof fetch = fetch` rather than `vi.spyOn(globalThis, 'fetch')` — cleanup is simpler and the production call site stays unchanged.
+- **Sentinels** are `role='system'` rows with structured `metadata.kind` (`cap_hit`, `doom_loop`). UI-only — `buildMessagesPayload` strips them via `isAnySentinel` so the LLM never sees them. A new kind requires arms in `MessageMetadata` in BOTH `apps/server/src/types/api.ts` AND `apps/web/src/api/types.ts`, plus a render branch in `apps/web/src/components/MessageBubble.tsx`.
+- **ReadableStream test stubs** use `pull()` (not `start()`) so chunks are produced lazily — `start()` enqueues everything and calls `controller.close()` before the consumer reads, so a subsequent `reader.cancel()` finds the stream already closed and the `cancel()` callback never fires. Also provide MORE chunks than the test will consume so the source stays in 'readable' state when cancel runs (e.g. cap test reads ~6 chunks, stub provides 10).
+- Tool-name whitelists must derive from `ALL_TOOLS` in `services/tools.ts`, never hardcoded. `services/agents.ts` `ALL_TOOL_NAMES` had this drift class until v1.12 — same pattern applies to any future tool-aware code.
+- Agent registry lives at `data/AGENTS.md` (global, bind-mounted at `/data/AGENTS.md`). No per-project `AGENTS.md` in this repo — removed in v1.12 to eliminate the two-files-must-stay-in-sync drift. The `getAgentsForProject` per-project override mechanism remains for *other* projects.
+- MCP stdio transport uses newline-delimited JSON (NDJSON), NOT LSP-style `Content-Length` headers. The `codecontext/shim.go` framing implementation is the reference; per the MCP spec (modelcontextprotocol.io/specification/server/transports).

------
+### v1.12.1 — commit consolidation
 
-## Roadmap doc deviations and corrections
+**Action items, in order:**
 
-This roadmap was significantly out of sync with reality until 2026-05-20. Key corrections folded in:
+1. **Remove diagnostic logging** from `apps/server/src/services/inference.ts`. The 12 `ctx.log.info` calls added today proved the inference loop was functioning correctly; the prompts were just slow. Verbose for production. Strip them, keep the file clean.
 
-1. **Batch 9 (Agents Tier 2) is done**, not "next up." Shipped as commit `92bd3b1`, included in v1.9.1 forward. The original "Track A: Batch 9 next" recommendation was correct but the doc never got updated.
+2. **Revert `detectSameNameLoop`.** Three additions in inference.ts:
-2. **v1.6.2 merged.** No longer "in flight."
+   - `DOOM_LOOP_SAME_NAME_THRESHOLD = 5` constant
-3. **Batch 5 (fork/delete), Batch 6 (drag-drop), Batch 7 (settings drawer), Batch 8 (web search), Batch 10 (BooTerm) all shipped**, scattered across the v1.6–v1.10 version line. Original "Track A polish then agents" plan was abandoned; work happened opportunistically.
+   - `detectSameNameLoop()` function
-4. **v1.11.0 was a major unplanned addition** — opencode-style compaction (auto-overflow detection + anchored rolling summary + tail preservation). This is NOT a batch from the old roadmap. It opened a new patch line (v1.11.x) of small follow-ups in front of the original Batches 11–17.
+   - Call site in `runAssistantTurn` immediately after the existing `detectDoomLoop` check
-5. **Batch 11 (codecontext sidecar) moves to v1.12.** Bundles with truncation and repair-tool-call lift (both from opencode) since they share concerns and the `tool_choice='required'` confirmation makes repair-tool-call viable.
-6. **Phase B (parts table + AI SDK + tool-call lifecycle) becomes v1.13.** This absorbs the old Batch 13 (append-only event log) — same outcome (typed message parts), different mental framing.
-7. **Phase C and Phase D are new** (numbered v1.14/v1.15). They originate from the opencode integration analysis, not from the original 17-batch plan. Phase C delivers the outer agent loop with explicit step boundaries. Phase D delivers the permission ruleset + MCP client needed for codecontext to be useful and for BooCoder to gate writes.
-8. **BooCoder (v2.0/v2.1)** is the second-major-version line. New container, new safety story (pending changes + per-session Docker sandbox). Maps to original Batches 14/15.
    
------
+   Never fired in any real run today. Dead code. The existing `detectDoomLoop` (identical args, threshold 3) is sufficient.
 
-## v1.11.x patches in detail
+3. **Drop the stale `messages_status_check` CHECK constraint** in `apps/server/src/schema.sql`. Two constraints exist on the table:
+   - `messages_status_check` allows `streaming|complete|failed` (old, stale)
+   - `messages_status_chk` allows `streaming|complete|failed|cancelled` (new)
    
-### v1.11.0 — opencode-style compaction port ✅
+   The old one prevents `cancelled` from being written. Drop it with `ALTER TABLE messages DROP CONSTRAINT IF EXISTS messages_status_check;`.
 
-**What shipped:** Auto-detection of context overflow (`isOverflow(usage, model)`) triggers compaction on the *next* user turn. Compaction preserves the last 2 turns verbatim and produces an anchored Markdown summary (8-section template lifted verbatim from opencode `compaction.ts`) that replaces older head messages. Summary is rolling — each new compaction updates the prior summary, not stacks. Schema additions: `messages.compacted_at`, `messages.summary`, `messages.tail_start_id`, `chats.needs_compaction`. WS `compacted` frame fires sonner toast on completion.
+4. **Stop-handler writes terminal status.** When user clicks stop mid-stream, the abort path must `UPDATE messages SET status='cancelled' WHERE id = $assistantMessageId AND status='streaming'`. Currently rows just sit `streaming` forever. The startup sweep catches them on restart, but they should be written immediately. Edit `apps/server/src/services/inference.ts` `handleAbortOrError` to add the UPDATE.
 
-**Key divergences from opencode:** Per-chat (not per-session) compaction state because BooCode history is per-chat. UUID `tail_start_id` not BIGINT. No `parent_id` on messages. Context limit comes from `messages.ctx_max` (last-known `n_ctx`), not a `model.context_limit` field.
+5. **Commit + tag v1.12.1.** Include the workspace pane sync, status indicator overhaul, startup sweep, and items 1–4 above. Single commit per item is fine; tag at end.
 
-### v1.11.1 — Compaction follow-up ✅
+**Estimated:** ~150 LoC net (deletions dominate).
 
-Working-state `chat_status: working/idle` frames around the LLM call inside `compaction.process()`. 24 new vitest cases for the six pure functions (`usable`, `isOverflow`, `estimate`, `turns`, `select`, `buildPrompt`). 7 `.bak-v1.11` files deleted.
+### v1.12.2 — live throughput display (small UX win)
 
-### v1.11.2 — ContextBar ✅
+Surface `tokens_per_second` and `ctx_used` next to the status indicator while streaming. Backend already emits these in the `usage` frame; just consume them in the StatusDot wrapper or a sibling component. ~80 LoC, frontend-only.
 
-New `ContextBar.tsx` rendering above MessageList. Shows `{used} / {max} ({pct}%)` with color tiers computed against `max - 20k` reserve (matches `compaction.usable()`): muted <60%, amber 60-80%, orange 80-95%, red ≥95%. Tooltip shows "Auto-compaction at ~N%". Mobile breakpoints: `< 380px` shows "Ctx" + numbers; `380-639px` adds parenthetical %; `≥ 640px` shows full "Context" label.
+### v1.12.3 — stale-stream frontend banner
 
-### v1.11.3 — ctx_max capture fix ✅
+When a chat has a `streaming` row older than ~60s with no new tokens, the UI should surface a "Previous response didn't complete. [Retry] [Discard]" banner instead of silently queueing new sends. Today's debugging spent four hours misreading slow streams as dead; this is the UX fix that prevents that. ~150 LoC, frontend + small backend endpoint for the discard action.
-
-Discovered the dead code at `inference.ts:479-481` and `compaction.ts:300` reading `parsed.timings.n_ctx` never fired — llama-server emits `prompt_n / predicted_n / *_ms / *_per_second` in timings but NOT `n_ctx`. New `model-context.ts` module fetches `GET /upstream/<model>/props` with 3s timeout, positive cache (no TTL), 60s negative cache. Wired into all 4 ctx_max write sites (3 in inference.ts, 1 in compaction.ts). 12 new vitest cases. 7 historical rows backfilled to `ctx_max = 262144` (single-day backfill, only qwen3.6-35b-a3b-mxfp4 in use).
-
-### v1.11.4 — CANCELLED
-
-Original scope: per-turn budget reset + Continue affordance + CapHitSentinel card. Recon revealed all three are already shipped (v1.8.2 timestamps in inference.ts comments). Dead version slot.
-
-### v1.11.5 — ContextBar relocate (DISPATCHED)
-
-Relocate ContextBar from above MessageList to above the agent-picker row. Bump height from ~4px bar to ~10-12px. Always-visible (zero-state when no assistant messages + use `model_context_limit` from v1.11.3 cache). Remove `ChatContextPopover` entirely (redundant signal; mobile-hostile).
-
-### v1.11.6 — Doom-loop guard (QUEUED)
-
-Detect 3 identical tool calls in a row within one turn (same name + same args via JSON.stringify). On detection: abort tool-call recursion, insert `metadata.kind='doom_loop'` sentinel, trigger summary turn via existing `runCapHitSummary` path. New `DoomLoopSentinel.tsx` component (no Continue button — looping shouldn't be retried with same tools). Per-turn sliding window, scoped to current turn's tool-call accumulator.
-
-**Lift source:** opencode `processor.ts`, `DOOM_LOOP_THRESHOLD = 3` constant.
-
-### v1.11.7 — pathGuard secrets filter (QUEUED)
-
-Extend pathGuard with `DEFAULT_SECURITY_IGNORE_FILETYPES` from continue.dev `core/indexing/ignore.ts`. Three-tier matcher: exact basenames (`credentials`, `secrets.yml`), extensions (`.env`, `.pem`, `.key`, `.crt`, etc.), prefix patterns (`id_rsa`, `id_dsa`, `id_ecdsa`, `id_ed25519`). Blocked files appear in `list_dir` and `find_files` results with `(blocked)` annotation. `view_file` returns `{ error: 'blocked_secret_file', ... }`. `grep` cannot read blocked file contents. No override mechanism in v1.x (use host shell).
-
-**Why it matters:** `/opt:/opt:ro` mount currently exposes `boolab/.env`, `dubdrive/users.json`, `authelia/state`, every other service's secrets to any tool past path validation. Cheap close on that surface area.
-
------
-
-## v1.12 — codecontext sidecar + truncation + repair tool call
-
-Three lifts fused because they share concerns:
-
-1. **codecontext sidecar** — new container, single-instance, path-addressed multi-project. Mount `/opt/projects:/workspace:ro`. 8 tools wired as static `ToolDef` wrappers in `apps/server/src/services/tools/codecontext/` (one file per tool). HTTP client to `http://codecontext:8765`. New module `apps/server/src/services/codecontext_bridge.ts` translates `project_id` → `/workspace/<relative>/` paths.
-
-2. **Tool output truncation** — opencode `truncate.ts` pattern. Cap at 2000 lines / 50KB. Larger outputs: write full content server-side, return preview + opaque `id`. New tool `view_truncated_output(id)` retrieves full content by server-mapped id. **No pathGuard exception** for `/tmp` directory — the opaque-id approach avoids exposing a writable filesystem location to the model. Only codecontext outputs need truncation; native tools (view_file 200 lines, grep 200 results, list_dir 500 entries, find_files 200 results) already cap reasonably.
-
-3. **`experimental_repairToolCall` equivalent** — when model emits malformed tool call (JSON parse fails or Zod validation fails), return a synthetic tool result instead of an error: `{ error, raw_args, tool_name, hint: 'Retry with valid JSON arguments.' }`. Model self-corrects on next step. Add one line to system prompt instructing self-correction on malformed-args results. Confirmed working precondition: `tool_choice: "required"` accepted by llama-swap (verified 2026-05-20 against qwen3.6-35b-a3b-mxfp4).
-
-**Hand-roll, not AI SDK adoption.** AI SDK migration deferred to v1.13.
-
-**AGENTS.md updates:** Each of the 6 builtin agents gets a curated codecontext tool whitelist:
-- Architect: all 8
-- Debugger: `search_symbols`, `get_dependencies`
-- Code Reviewer: `get_file_analysis`
-- Refactorer: `get_semantic_neighborhoods`, `get_dependencies`
-- Security Auditor: `get_file_analysis`, `search_symbols`, `get_dependencies`
-- Prompt Builder: none (no structural reasoning relevance)
-
-**Dependencies:** v1.11.x merged. No others.
-
-**Estimated:** 600 LoC across 3-4 dispatches under the v1.12 umbrella.

 ### Schema additions by version
 
 - **v1.11.0:** `messages.compacted_at`, `messages.summary`, `messages.tail_start_id`, `chats.needs_compaction`
 - **v1.11.7:** none (pathGuard logic, no DB)
-- **v1.12:** none (codecontext is stateless on disk; truncation uses in-memory id→path map with TTL cleanup)
+- **v1.12.0:** none (codecontext stateless; truncation in-memory id-map with TTL cleanup)
+- **v1.12.1:** `sessions.workspace_panes jsonb` (workspace sync); drop deprecated `session_panes` table; drop stale `messages_status_check` constraint
 - **v1.13:** `message_parts` table; `messages` becomes header-only
 - **v1.14:** `agents.steps` column (or AGENTS.md parser extension; no DB if file-only)
 - **v1.15:** `permissions` table, `agent_permissions` join, `session_permissions` join

+- **v1.11.4 cancelled** (2026-05-20). Per-turn budget reset + Continue affordance + CapHitSentinel were already shipped in v1.8.2.
+- **v1.12.0 shipped** (2026-05-21). codecontext sidecar Track B + container guidance Track A. v1.12 truncation and repairToolCall were deferred into v1.13's AI SDK migration where they get for-free.
+- **v1.12.1 workspace pane sync** (2026-05-21). Moved pane state from per-device localStorage to `sessions.workspace_panes jsonb` with WS broadcast for cross-device sync. Deprecated `session_panes` table dropped. Legacy localStorage migrates on first load.
+- **v1.12.1 status indicator overhaul** (2026-05-21). ChatStatusFrame expanded from `working|idle|error` to `streaming|tool_running|waiting_for_input|idle|error`. StatusDot rewritten with distinct animations per state. Added `executeToolPhase`-entry `tool_running` publish.
+- **detectSameNameLoop reverted** (planned v1.12.1). Added during the 2026-05-21 debugging spike to catch same-tool-name-with-different-args loops. Never fired in any real run because the existing `detectDoomLoop` covers the actual failure modes. Dead code, reverting.
+- **The 2026-05-21 "freeze" debugging spike taught one lesson**: BooCode has no UI signal for the difference between a slow stream and a dead stream. Diagnostic logging (added today, reverted in v1.12.1) revealed the inference loop was working correctly throughout — what looked like four hours of deterministic hang was multiple instances of qwen3.6 generating 8k tokens of self-doubt at temperature 0.2 on a "find the bug" prompt with no real bug. v1.12.2 (live tok/s display) and v1.12.3 (stale-stream banner) directly address this gap.
