docs: refine CLAUDE.md (TurnArgs, web tools, env vars, new-tool convention)

Adds two new tools registered through the existing ALL_TOOLS registry:
  - web_search hits SearXNG's JSON API (Fathom, internal Tailscale URL,
    no auth) and returns top results
  - web_fetch retrieves a URL's text content, gated by isPublicUrl
    (url_guard.ts) which blocks loopback / RFC1918 / Tailscale CGNAT /
    link-local / .local / .internal / non-http schemes

Both tools are opt-in via the existing session.web_search_enabled flag
(plumbed in v1.9, activated here). Default off. UI labels updated to
"Enable web search and fetch" / "Web search and fetch" since fetch joins
the same store. Counts against the v1.8.2 per-turn budget; covered by
the v1.11.6 doom-loop guard.

Native Node 20 fetch — no new prod dep. HTML stripping via regex (script
and style content elided wholesale). 5MB body cap, 15s fetch timeout,
8000-char default output, 32000-char cap.

+- **`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).

+
+Last updated: 2026-05-20
+
+This document tracks every open source repo BooCode references or lifts code from. Pin this so we don't lose attribution and don't re-evaluate the same projects twice.
+
+BooCode is personal/single-user — license compatibility is non-blocking, but the License column is recorded so we don't accidentally inherit an obligation if BooCode ever goes public.
+
+-----
+
+## Reference repos
+
+### Tier A — actively lifting from / running as sidecar
+
+#### 1. sst/opencode (NEW Tier A as of 2026-05-20)
+
+- **URL:** https://github.com/sst/opencode
+- **License:** MIT
+- **Language:** TypeScript (Effect-TS service-oriented)
+- **What it is:** The coding agent Sam uses via Termius/Paseo. Also the source of every algorithm BooCode is porting through v1.15.
+- **Why it matters:** opencode's `packages/opencode/src/session/` is the canonical reference implementation for every part of the inference layer BooCode is rebuilding. We lift the algorithms, not the Effect-TS plumbing.
+- **Algorithms lifted so far:**
+  - `session/compaction.ts` → v1.11.0 (shipped). `usable`, `isOverflow`, `select`, `buildPrompt` ported to plain TS. SUMMARY_TEMPLATE markdown skeleton verbatim.
+  - `session/overflow.ts` → v1.11.0 (shipped). 20k `COMPACTION_BUFFER` constant.
+- **Algorithms lifted (queued):**
+  - `session/processor.ts` `DOOM_LOOP_THRESHOLD=3` → v1.11.6
+  - `session/llm.ts` `experimental_repairToolCall` → v1.12 (hand-rolled), then v1.13 (via AI SDK)
+  - `tool/truncate.ts` truncation + outputPath pattern → v1.12 (adapted: opaque id, not filesystem path)
+  - `session/prompt.ts` `runLoop()` outer agent loop → v1.14
+  - `permission/evaluate.ts` wildcard ruleset → v1.15
+  - MCP client (transport, tools/list discovery, tools/call) → v1.15
+- **What NOT to use:** Effect-TS service plumbing. Snapshot/patch system (for tool-edit revert; BooCoder territory if needed). The `experimental_native_runtime` (AI SDK fallback path). opencode's prompts.
+- **Source tag:** `dev` branch on `sst/opencode`. Note: `anomalyco/opencode` is a rebranded mirror; use `sst/opencode` as canonical.
+
+#### 2. nmakod/codecontext
+
+- **URL:** https://github.com/nmakod/codecontext
+- **License:** MIT
+- **Language:** Go (single binary)
+- **What it is:** AI-oriented codebase context map generator. Tree-sitter parsing across TS/JS/Go/C++/Swift/Python/Java/Rust/Dart/JSON/YAML. Generates `CLAUDE.md`-style structured overview. Bundled MCP server with 8 tools.
+- **MCP tools exposed:** `get_codebase_overview`, `get_file_analysis`, `get_symbol_info`, `search_symbols`, `get_dependencies`, `watch_changes`, `get_semantic_neighborhoods` (git co-change patterns — no embeddings), `get_framework_analysis`.
+- **Why it matters:** Solves the "architect needs a map" problem without embeddings.
+- **How we use it:** Run as sidecar container in v1.12. Wire its MCP tools into BooCode's `inference/tools.ts` as static wrappers in v1.12, then re-wire via real MCP client when v1.15 ships.
+- **What NOT to use:** Nothing. Clean fit.
+
+#### 3. aimasteracc/tree-sitter-analyzer
+
+- **URL:** https://github.com/aimasteracc/tree-sitter-analyzer
+- **License:** MIT
+- **Language:** Python, MCP server + CLI
+- **What it is:** Local-first code context engine. Outline-first navigation, ripgrep-based impact trace, no embeddings. 17 languages. Claims 54-56% token reduction via TOON format.
+- **MCP tools exposed:** `get_code_outline`, `trace_impact`, plus structural search/extract tools.
+- **Why it matters:** Backup analyzer with a different response shape — outline-first scales better than codecontext's full dump on huge files. Impact trace is useful for "what calls this function" without a full graph build.
+- **How we use it:** Lift the AST query patterns (`.scm` files) and the outline-first response shape. Can also run as a second MCP sidecar alongside codecontext.
+- **What NOT to use:** Don't lift the TOON format if it conflicts with shadcn rendering — markdown stays.
+
+#### 4. spirituslab/codesight
+
+- **URL:** https://github.com/spirituslab/codesight
+- **License:** check repo — assumed MIT-ish
+- **Language:** TypeScript/Node
+- **What it is:** Static code structure visualization. Symbol extraction, import resolution, call graphs. Detects circular dependencies and dead code (with documented false-positive caveats for `customElements.define()`, framework entry points, dynamic imports).
+- **Why it matters:** Gives BooCode a `repo_health` tool — different from codecontext's "what is this" map. This is "what's wrong with this."
+- **How we use it:** v1.16. Port the analyzer core (`analyze.mjs`). Call-graph builder + circular-dep + dead-code detectors into BooCode's `tools/repo_health.ts`. Drop the VS Code extension shell entirely.
+- **What NOT to use:** The VS Code wrapper, the "idea layer" feature (requires Copilot or Claude Code wiring we don't want).
+
+#### 5. Aider-AI/aider
+
+- **URL:** https://github.com/Aider-AI/aider
+- **License:** Apache-2.0
+- **Language:** Python
+- **What it is:** Git-native AI pair programmer CLI. Pioneered the tree-sitter repo-map + personalized PageRank approach.
+- **Why it matters:** Authoritative source of per-language `tags.scm` query files. 60+ languages curated and battle-tested.
+- **How we use it:** **Lift directly:** `aider/queries/tree-sitter-*.scm` — drop into BooCode's analyzer for any language codecontext or codesight don't cover natively.
+- **What NOT to use:** Don't port `repomap.py` itself — codecontext supersedes it.
+
+-----
+
+### Tier B — patterns / partial lift
+
+#### 6. continuedev/continue
+
+- **URL:** https://github.com/continuedev/continue
+- **License:** Apache-2.0
+- **Language:** TypeScript
+- **What it is:** IDE assistant framework. Full RAG pipeline, AST chunking, multi-provider LLM abstraction.
+- **Why it matters:** One specific drop-in lift:
+  1. `core/indexing/ignore.ts` — `DEFAULT_SECURITY_IGNORE_FILETYPES`. Three-tier matcher (basenames, extensions, prefixes). Going into BooCode's `pathGuard` to block analyzing `.env`, `.pem`, `id_rsa`, etc.
+- **How we use it:** v1.11.7. Lift the ignore list, adapt to a `path.basename` + extension + prefix matcher.
+- **What NOT to use:** `core/indexing/CodebaseIndexer.ts` and `LanceDbIndex.ts` — embedding-based, the path we walked away from.
+
+#### 7. cline/cline
+
+- **URL:** https://github.com/cline/cline
+- **License:** Apache-2.0
+- **Language:** TypeScript (VS Code extension)
+- **What it is:** Autonomous coding agent. Pioneered plan/act mode and granular per-tool auto-approve.
+- **Why it matters:** Pattern source for v1.15 (absorbed into the broader permissions work). Plan/act invariant: in plan mode, write tools hidden from the model's tool registry; in act mode, available but each individual tool can be approval-gated.
+- **How we use it:** Lift the *pattern*, not the code. opencode's `permission/evaluate.ts` wildcard ruleset supersedes cline's mode-enum; cline contributes the conceptual framing (read-only invariant in BooCode v1.x).
+- **What NOT to use:** Cline's VS Code-specific UI plumbing. The shape is wrong for our stack.
+
+#### 8. plandex-ai/plandex
+
+- **URL:** https://github.com/plandex-ai/plandex
+- **License:** MIT
+- **Language:** Go
+- **What it is:** Terminal agent with a pending-changes sandbox. Edits never touch the filesystem until `/apply`. 2M token context.
+- **Why it matters:** Reference architecture for BooCoder (v2.0). The "edits queue in a virtual layer, applied atomically" model is the right safety story for write tools.
+- **How we use it:** Lift the data model: `pending_changes` table keyed by `(project_id, session_id, file_path)`, with diff content and apply/reject state. Lift the `diff` / `apply` / `rewind` UX vocabulary.
+- **What NOT to use:** Plandex's 2M-context-window engineering. Our context is bounded by llama-swap.
+
+#### 9. OpenHands/OpenHands
+
+- **URL:** https://github.com/OpenHands/OpenHands
+- **License:** MIT
+- **Language:** Python
+- **What it is:** Autonomous coding agent platform. V1 architecture is built on an append-only typed event log + Docker sandbox runtime.
+- **Why it matters:** Two distinct patterns:
+  1. Event-log architecture — superseded by v1.13's parts-table approach (which derives from opencode's part-message model). OpenHands event-log is conceptually similar but different shape.
+  2. Sandbox runtime — per-session Docker container for write tools. Closes the `/opt:ro` mount risk.
+- **How we use it:** v2.1. Lift the runtime container pattern (HTTP API inside container, BooCoder calls in). Don't port the Python implementation directly.
+- **What NOT to use:** OpenHands' agent prompts, the full microagent system, the cloud deployment path. Event-log shape (use opencode-derived parts table instead).
+
+-----
+
+### Tier C — reference only / partial use / skip
+
+#### 10. cortexkit/aft (actual repo path: ualtinok/aft)
+
+- **URL:** https://github.com/ualtinok/aft
+- **License:** check repo
+- **Language:** Rust binary + TypeScript plugin
+- **What it is:** Tree-sitter analysis tools delivered as a Rust binary, communicating with an OpenCode plugin via JSON-over-stdio. Warm-process pattern: one binary per project keeps parse trees in memory.
+- **Why it matters:** The BridgePool transport model. If our `codecontext` tool calls get hot (agent loops calling it dozens of times per session), the warm-process pattern is faster than fork-per-call.
+- **How we use it:** **Defer.** Profile first. Codecontext sidecar might be fast enough on its own. Revisit if tool-call latency becomes the bottleneck.
+- **What NOT to use:** The opencode-plugin wrapper. Wrong integration surface.
+
+#### 11. codeprysm/codeprysm
+
+- **URL:** https://github.com/codeprysm/codeprysm
+- **License:** check repo
+- **Language:** Rust
+- **What it is:** Graph-based code intelligence: tree-sitter parsing → node/edge graph in Qdrant, embeddings layered on top, MCP server exposes semantic search.
+- **Why it matters:** Clean node/edge taxonomy: nodes = Container/Callable/Data; edges = CONTAINS/USES/DEFINES.
+- **How we use it:** Lift the taxonomy *only* if we end up building our own graph instead of relying on codecontext. The embedding half is the trap we walked away from.
+- **What NOT to use:** The Qdrant + embedding pipeline. Same anti-pattern as continue's indexer.
+
+#### 12. DeepSourceCorp/globstar
+
+- **URL:** https://github.com/DeepSourceCorp/globstar
+- **License:** MIT
+- **Language:** Go
+- **What it is:** Static analysis toolkit for writing code checkers using tree-sitter S-expression queries. YAML interface for simple checkers, Go interface for complex multi-file checkers.
+- **Why it matters:** Not for the architect tool. **Future use only.** If BooCoder ever grows a "verify before commit" lane, globstar checkers could be the verification engine: drop YAML checkers into `.globstar/`, run as a pre-apply gate.
+- **How we use it:** Park. Not in any current version.
+- **What NOT to use:** Don't try to use it as a codebase analyzer — it's a linter framework, wrong tool for the architect role.
+
+#### 13. getpaseo/paseo
+
+- **URL:** https://github.com/getpaseo/paseo
+- **License:** AGPL-3.0
+- **What it is:** WebSocket daemon ↔ client protocol for agent coordination. Already running in your stack (paseo dispatches Claude Code/opencode).
+- **Why it matters:** Patterns for agent lifecycle, `--worktree` flag pattern, ECDH/NaCl security model.
+- **How we use it:** Reference for BooCoder isolation (v2.0/v2.1). Note AGPL — fine for personal, blocks public distribution.
+- **What NOT to use:** Don't vendor the source. Treat as a peer service.
+
+#### 14. earendil-works/pi
+
+- **URL:** https://github.com/earendil-works/pi
+- **License:** MIT
+- **What it is:** `@mariozechner/pi-agent-core` (tool loop + state machine) and `@mariozechner/pi-ai` (provider abstraction).
+- **Why it matters:** If we ever want non-llama-swap inference (Anthropic, OpenAI, Mistral direct), pi-ai is the cleanest TypeScript provider abstraction available.
+- **How we use it:** Defer. v2.x optional batch only.
+
+#### 15. microsoft/agent-framework
+
+- **URL:** https://github.com/microsoft/agent-framework
+- **License:** MIT
+- **What it is:** Workflow graphs for multi-agent coordination.
+- **Why it matters:** Conceptual reference for far-future multi-agent orchestration.
+- **How we use it:** Read the ADRs in `docs/decisions/`. Don't port code — implementation is Azure/Python/.NET-heavy.
+
+#### 16. microsoft/autogen
+
+- **URL:** https://github.com/microsoft/autogen
+- **License:** MIT
+- **What it is:** Earlier Microsoft multi-agent framework.
+- **Why it matters:** Effectively sunsetting in favor of agent-framework.
+- **How we use it:** Skip. Don't invest in evaluating further.
+
+#### 17. open-webui/open-webui
+
+- **URL:** https://github.com/open-webui/open-webui
+- **License:** BSD-3
+- **What it is:** Self-hosted LLM frontend.
+- **Why it matters:** Python/Svelte, wrong stack. RAG pipeline only worth a read if BooLab needs improvement — unrelated to BooCode.
+- **How we use it:** Skip for BooCode.

+## Decisions log
+
+- **Embeddings dropped from BooCode** (May 2026). Replaced RAG with file-view tools + sidecar analyzers.
+- **opencode promoted to Tier A** (2026-05-20). The compaction port (v1.11.0) made it clear opencode is not just "the agent Sam uses" — it's the canonical reference implementation for everything BooCode is rebuilding through v1.15. Five algorithms identified for lift (compaction, doom-loop, repairToolCall, runLoop, permission evaluate) plus truncate.ts and MCP client.
+- **Source is `sst/opencode` `dev` branch.** `anomalyco/opencode` is a rebranded mirror; do not source from there.
+- **Original Batch 11 (aider PageRank port) replaced** by codecontext sidecar approach.
+- **Original Batch 12 (codebase indexer w/ Harrier) removed.** No embedding infrastructure.
+- **Original Batch 13 (OpenHands event log) replaced** by v1.13 parts table (opencode pattern). Same outcome, different shape.
+- **Original Batch 12 (cline plan/act mode) absorbed into v1.15** (opencode permission ruleset). Same outcome, wildcard rules instead of mode enum.
+- **Aider's `repomap.py` port dropped.** Codecontext supersedes it. Aider contribution narrows to the `.scm` query files only.
+- **Globstar role re-scoped.** Not an architect tool — parked for future verify-before-commit gate.
+- **codeprysm role re-scoped.** Taxonomy reference only. Embedding half rejected.
+- **AI SDK adoption deferred to v1.13.** Hand-roll opencode's repairToolCall pattern in v1.12 first.
+- **`tool_choice='required'` confirmed supported** by llama-swap (qwen3.6-35b-a3b-mxfp4, 2026-05-20). Repair tool call is viable.
+- **`anomalyco/sst` is a mirror, not a fork.** Same applies to `anomalyco/opencode`. Use canonical `sst/sst` and `sst/opencode` sources.

 ## Overview
 
-BooCode is a standalone code-chat tool at `/opt/boocode/`. Read-only by design in v1.x — pick a project, chat with a local LLM that has file-inspection tools, get streaming responses over WebSocket.
+BooCode is a standalone code-chat tool at `/opt/boocode/`. Read-only by design — pick a project, chat with a local LLM that has file-inspection tools, get streaming responses over WebSocket.
 
 Live at `https://code.indifferentketchup.com` (Caddy → Authelia → Tailscale → `100.114.205.53:9500`).
 
 **Architectural commitments:**
 
-- No embeddings. File-view tools + sidecar analyzers replace RAG.
+- No embeddings. The model uses file-view tools (`view_file`, `list_dir`, `grep`, `find_files`) + sidecar analyzers (codecontext, codesight). Walked away from the RAG pipeline May 2026.
 - Read-only in v1.x. Write tools land in BooCoder (separate container, post-v1.x).
 - One Postgres (`boocode_db`), one frontend SPA, container-per-service for new capabilities.
 
-## Current state
+External code lifted from / referenced in: see `boocode_code_review.md` for full inventory.
 
-- **main:** v1.8.1 (`b09d0ff` was last known tip prior to v1.8.2).
+-----
-- **Just merged / committed to main:** v1.8.2 — tool-loop fixes (read-only loop cap raised, "tool loop depth exceeded" error surfaced with continue button, `max_tool_calls` AGENTS.md frontmatter, `messages.metadata` column).
-- **In flight RIGHT NOW:** **v1.x-themes** branch — Claude Code implementing 18-theme system. See "Active work" below.

-- API: GET `/api/settings` extended, PATCH whitelists 18 theme ids → 400 otherwise
-- CSS: `apps/web/src/styles/themes/*.css` (18 + `_tokens.css`), imported from `globals.css` (NOT `index.css`)
-- `.theme-<id>` + `.theme-<id>.dark` composed on `<html>`
-- `apps/web/src/lib/theme.ts` (new): `THEMES` const, `applyTheme(id, mode)`, `useTheme()` hook. matchMedia subscribed only when `mode === 'system'`
-- `apps/web/src/App.tsx`: `useTheme()` at top
-- Settings page: card grid, mode toggle (radio: Dark/Light/System). No header dropdown.
-- shadcn primitives: `card`, `radio-group` installed via `pnpm dlx shadcn@latest add`. `button`, `label` already present.
-- FOUC mitigation: localStorage cache + inline `<script>` in `index.html` sets `<html>` class before React hydrates
-
-**Out of scope (v1):**
-- Custom user palettes (no color picker)
-- Per-project / per-session themes
-- Shiki syntax-highlighting themes
-- Header quick-switcher
-
-**Verify after Claude Code hands back:**
-- `fuchsia-noir` and `midnight-sapphire` visual check — derived, not from preview. Swap hexes if they read wrong.
-- Light variants of the 16 dark themes — algorithmic. Spot-check 3-4 across families (warm/cool/dark/saturated).
-- FOUC on hard reload, theme-switch persistence, system-mode matchMedia teardown.

-## Flagged follow-ups (not in a batch yet)
+-----
 
-- Agents in `/data/AGENTS.md` don't list `git_status` in their `tools:` blocks. Out of scope until pre-BooCoder cleanup pass.
+## Major work after v1.11.x
-- v1.9 dispatch had item (g): verify `useUserEvents` broadcasts `project_updated` on PATCH `/projects/:id`. Add if missing.
-- v1.8.2 follow-up: confirm `messages.metadata` migration ran clean in prod DB after deploy.
 
-## Order of operations
+| Version | Theme | LoC est. |
+|---|---|---|
+| **v1.12** | codecontext sidecar + tool output truncation + repair tool call (Integration 1 + 3 from May review, fused) | ~600 |
+| v1.13 | Phase B groundwork — parts table + AI SDK adoption + per-tool `read_only`/`write` tagging | ~1500 |
+| v1.14 | Phase C — outer agent loop (multi-step until non-tool finish, AGENTS.md `steps` field, reasoning as part type) | ~800 |
+| v1.15 | Phase D — permission ruleset + MCP client (lays foundation for BooCoder) | ~600 |
+| v1.16 | Batch 11b — codesight repo_health (call graph, circular deps, dead code) | ~400 |
+| **v2.0** | Batch 14 — BooCoder pending changes (new container, write tools, plandex pattern) | ~1200 |
+| v2.1 | Batch 15 — BooCoder runtime isolation (per-session Docker sandbox, OpenHands pattern) | ~600 |
+| v2.x | Batch 16/17 — Multi-provider LLM (optional, pi-ai) and Workflow graphs (far future, agent-framework concepts) | tbd |
 
-1. **v1.x-themes** finishes (Claude Code in flight). Audit + smoke test. Merge.
+-----
-2. **v1.8.3** — tool call UI compaction. Small frontend batch, addresses current pain.
-3. **v1.9** — settings pane. Branch already named `v1.9-settings-pane`. Spec locked.
-4. **v1.10** — web search backend.
-5. **v1.11** — agents.
-6. **v1.12** — BooTerm.
 
-Track B (architect, no UI dep, can run parallel anytime): v1.13 → v1.13b → v1.14.
+## Roadmap doc deviations and corrections
+
+This roadmap was significantly out of sync with reality until 2026-05-20. Key corrections folded in:
+
+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. **v1.6.2 merged.** No longer "in flight."
+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.
+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.
+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.
+
+-----
+
+## v1.11.x patches in detail
+
+### v1.11.0 — opencode-style compaction port ✅
+
+**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.
+
+**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.
+
+### v1.11.1 — Compaction follow-up ✅
+
+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.
+
+### v1.11.2 — ContextBar ✅
+
+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.
+
+### v1.11.3 — ctx_max capture fix ✅
+
+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.
+
+-----
+
+## v1.13 — Phase B: parts table + AI SDK + per-tool tagging
+
+**Goal:** typed message parts replace JSON blobs on `messages.tool_calls` / `tool_results`. Adopt Vercel AI SDK `streamText`. Tag tools as `read_only` or `write` at definition time.
+
+**Scope:**
+
+1. Schema: new `message_parts` table (`id, message_id, kind, payload JSONB, sequence`). Kinds: `text`, `tool_call`, `tool_result`, `reasoning`, `step_start`. The `messages` table becomes header-only.
+2. Inference loop rewritten on AI SDK `streamText`. `streamCompletion` becomes a thin wrapper. Native AI SDK `experimental_repairToolCall` replaces v1.12's hand-rolled version.
+3. Tool registry: `ToolDef<T>` gains `category: 'read_only' | 'write'` field. BooCode v1.x rejects any `write` tool at registry time (defense in depth for the BooCoder split). Alpha-sort tool list before sending to model (prompt-cache stability).
+4. Reasoning content (`reasoning_content` from Qwen3.6) captured as its own part type instead of dropped or inlined.
+
+**Migration risk:** non-trivial. inference.ts is ~1400 lines with custom XML fallback, SSE parsing, compaction integration. Plan dedicated cutover window. Compaction.ts must update to assemble head from parts.
+
+**Replaces:** Original Batch 13 (append-only event log) — same outcome, different vocabulary.
+
+**Dependencies:** v1.12 merged.
+
+-----
+
+## v1.14 — Phase C: outer agent loop
+
+**Goal:** explicit multi-step loop per opencode `prompt.ts` `runLoop()`. Replace the current ad-hoc tool-call recursion.
+
+**Scope:**
+
+1. Outer loop continues until model returns non-tool finish OR step cap hit. Step ≠ tool call: one step can contain multiple tool calls in parallel.
+2. `agent.steps ?? Infinity` per-agent step cap. AGENTS.md gains `steps:` field. Refactorer `steps: 5`, Architect `steps: 20`, etc.
+3. Step-boundary events (`step_start`, `step_finish`) explicit in the parts stream. Per-step snapshot for revert (planned for BooCoder; backend-only in v1.14).
+4. Doom-loop guard (v1.11.6) migrates from "abort recursion" to "raise within loop iteration." Same predicate, different control flow.
+
+**Dependencies:** v1.13 merged.
+
+-----
+
+## v1.15 — Phase D: permission ruleset + MCP client
+
+**Goal:** wildcard permission ruleset (opencode `evaluate.ts` pattern) and a proper MCP client implementation. Foundation for BooCoder to gate writes; immediate value for codecontext to be re-wired as a real MCP server.
+
+**Scope:**
+
+1. Wildcard rule matcher: `{ permission, pattern, action: 'allow' | 'deny' | 'ask' }`. Last-match-wins. Per-agent rulesets layer under per-session rulesets.
+2. MCP client implementation: SSE transport, `tools/list` discovery, `tools/call` invocation. codecontext sidecar gets re-pointed from static wrappers (v1.12) to real MCP. New connectors become a config-only addition.
+3. UI: permission-ask flow when a tool requires `ask` action. Modal or inline card with Allow once / Allow always / Deny.
+4. v1.x stays read-only by default (no `write` tools in the registry yet).
+
+**Absorbs:** Original Batch 12 (tool approval + plan/act mode) — same outcome via permission rules instead of mode enum.
+
+**Dependencies:** v1.13 merged (parts table for permission events). Independent of v1.14.
+
+-----
+
+## v1.16 — Batch 11b: codesight repo_health
+
+Call graph, circular dependency detection, dead code flagging. Port `analyze.mjs` from spirituslab/codesight. New tool `repo_health(project_id)`. In-process Node (not sidecar). Cache results keyed by `(project_id, file_hashes_sig)`.
+
+**Dependencies:** v1.12 merged (can reuse codecontext parse output where overlapping).
+
+-----
+
+## v2.0 — BooCoder pending changes
+
+New container `boocoder` at `100.114.205.53:9502`. Owns write tools (`edit_file`, `create_file`, `delete_file`, `apply_pending`, `rewind`). Edits queue in `pending_changes` table; nothing touches disk until `/apply`. Per-pane diff UI with Approve/Reject. BooCode chat stays read-only (`/opt:/opt:ro`).
+
+**Lift source:** plandex pending-changes data model.
+
+**Dependencies:** v1.13 (parts) + v1.15 (permissions).
+
+-----
+
+## v2.1 — BooCoder runtime isolation
+
+Per-session Docker sandbox spawned by BooCoder on first write. Only project path mounted, not `/opt`. Idle-timeout 30 min. Standard OpenHands runtime contract: HTTP API inside container, BooCoder calls in.
+
+**Lift source:** OpenHands V1 runtime pattern.
+
+**Dependencies:** v2.0.
+
+-----
+
+## v2.x — Optional / far future
+
+- **Multi-provider LLM** (pi-ai pattern): Only if a concrete need for Anthropic / OpenAI / Mistral direct surfaces. llama-swap covers everything today.
+- **Workflow graphs** (microsoft/agent-framework concepts): Multi-agent coordination. Conceptual reference only. Realistically a v3.x topic.

 ## Decisions log
 
-- Embeddings dropped from BooCode. File-view tools + sidecar analyzers replace RAG.
+- **Embeddings dropped from BooCode** (May 2026). Replaced RAG with file-view tools + sidecar analyzers.
-- Old Batch 11 (aider PageRank port) → replaced by codecontext sidecar (v1.13).
+- **Original Batch 11 (aider PageRank port) replaced** by codecontext sidecar approach.
-- Old Batch 12 (Harrier indexer) → removed entirely.
+- **Original Batch 12 (codebase indexer w/ Harrier) removed.** No embedding infrastructure in BooCode v1.x.
-- Batch 9 reordered ahead of 5–8, decoupled from Batch 7 (2026-05-16). Subsequently superseded — settings pane (v1.9) and themes (v1.x-themes) jumped ahead. Agents now slated as v1.11.
+- **Globstar parked** — not an architect tool. Future verify-before-commit candidate only.
-- Theme work split into its own version (v1.x-themes) rather than blocked behind v1.9 (2026-05-17). Branched off main after v1.8.2 committed.
+- **codeprysm rejected** — embedding-based. Node/edge taxonomy noted as reference if we ever build our own graph.
+- **Batch 9 decoupled from Batch 7 (2026-05-16); shipped in `92bd3b1`.** Builtin defaults: six agents (Code Reviewer, Debugger, Refactorer, Architect, Security Auditor, Prompt Builder) with no `model` field. Session model wins by default.
+- **opencode lift opened** (2026-05-20). Started with compaction (v1.11.0). Continuing through v1.15. Five distinct algorithms: compaction, doom-loop guard, repairToolCall, runLoop, permission evaluate. Plus `truncate.ts` and `MCP client`. Each lifts the algorithm, not the Effect-TS plumbing.
+- **AI SDK adoption deferred to v1.13.** Hand-roll repairToolCall in v1.12 first. Migrate everything together when parts table lands.
+- **`tool_choice='required'` confirmed supported** by llama-swap (qwen3.6-35b-a3b-mxfp4, 2026-05-20). Unblocks repair tool call viability.
+- **v1.11.4 cancelled** (2026-05-20). Per-turn budget reset + Continue affordance + CapHitSentinel were already shipped in v1.8.2. Roadmap was 14 versions stale at time of recon.

 ## Workflow
 
 Each batch:
-1. Verify previous merged.
-2. Dispatch via Paseo to Claude Code at `/opt/boocode` (or OpenCode for smaller batches).
-3. Recon → blocking questions → implement → hand back.
-4. Compliance review in separate Claude chat.
-5. Deploy: `docker compose up --build -d`.
-6. Smoke test.
-7. Sam commits and pushes.
 
-Sam reviews all diffs. Sam commits. Never git pull/push/commit on his behalf.
+1. Verify previous batch merged. `git log --oneline main -5`.
+2. Cut branch from main. Single-branch-per-dispatch convention.

+4. Claude Code recon → blocking questions → implement → hand back.
+5. Compliance review in separate Claude chat (paste handback).
+6. Build: `docker compose build --no-cache boocode` (no-cache avoids the v1.11.2 stale-bundle trap).
+7. Restart: `docker compose up -d boocode`.
+8. Smoke test in browser (hard refresh).
+9. Sam commits and pushes. **Never** `git pull` / `git push` / `git commit` on his behalf.
