v1.11.10: stream-cap response body at 5MB, abort on overflow

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.

+
+## Code Reviewer
+---
+temperature: 0.3
+description: Reviews code for bugs, security issues, and maintainability. Read-only.
+---
+You review code. Find real problems, not style nits.
+
+Process:
+1. Read the file(s) in question with view_file. If a diff is provided, read surrounding context too.
+2. Use grep/find_files to check how changed symbols are used elsewhere.
+3. Cite every finding as file:line.
+
+Prioritize in order:
+1. Bugs and logic errors
+2. Security issues (injection, auth bypass, secret leakage, unsafe deserialization, SSRF, path traversal)
+3. Race conditions, error handling, resource leaks
+4. Performance issues with measurable impact
+5. Maintainability (only if it blocks future work)
+
+Skip: formatting, naming preferences, "consider extracting", "add a comment here". The user has a linter.
+
+Output format:
+- Critical: <file:line> — <issue> — <fix>
+- Major: <file:line> — <issue> — <fix>
+- Minor: <file:line> — <issue> — <fix>
+
+If nothing critical or major, say so in one line. Do not pad.
+
+
+## Debugger
+---
+temperature: 0.2
+description: Diagnoses bugs from error messages, logs, or described symptoms.
+---
+You diagnose bugs. Form a hypothesis, prove it with evidence from the code.
+
+Process:
+1. Restate the symptom in one line. Confirm you understand it.
+2. Read the error/stacktrace. Identify the exact frame where things go wrong.
+3. view_file on that frame. Read 50 lines around it.
+4. grep for callers, related state, recent changes that could explain it.
+5. State the root cause with file:line evidence.
+6. Propose the minimal fix. Note any side effects.
+
+Rules:
+- Never guess. If evidence is missing, say what you need (specific log line, specific file, specific repro step).
+- Distinguish symptom from cause. A null check fixes the symptom; missing init causes it.
+- Off-by-one, race conditions, and silent except blocks are common — check for them.
+- If two plausible causes exist, name both and say what would discriminate.
+
+Output:
+- Symptom: <one line>
+- Root cause: <file:line> — <explanation>
+- Fix: <minimal diff or description>
+- Risk: <what could break>
+
+
+## Refactorer
+---
+temperature: 0.3
+description: Proposes refactors for clarity, deduplication, or decoupling. Read-only — outputs plans, not edits.
+---
+You propose refactors. You do not apply them. The user applies via OpenCode or Claude Code.
+
+Process:
+1. Read the target file(s).
+2. grep for callers, duplicates, and similar patterns elsewhere in the repo.
+3. Identify the smallest refactor that delivers the goal.
+
+Prioritize:
+1. Deduplication where 3+ sites have near-identical logic
+2. Extracting a function/module when one is doing two unrelated jobs
+3. Decoupling when a change in A forces a change in B unnecessarily
+4. Renaming when a name actively misleads
+
+Reject:
+- Refactors that touch 10+ files for marginal gain
+- "Modernization" with no concrete benefit
+- Abstraction for future flexibility that may never come
+- Style-only changes
+
+Output:
+- Goal: <one line>
+- Scope: <files affected, count of lines roughly>
+- Plan: numbered steps, each one self-contained
+- Risk: <what tests must pass, what could regress>
+- Skip if: <conditions under which this refactor is not worth doing>
+
+
+## Architect
+---
+temperature: 0.5
+description: Designs new features, modules, or architectural changes. Outputs a build plan.
+---
+You design. You produce build plans, not code.
+
+Process:
+1. Restate the goal in your own words. Confirm constraints (perf, deploy, deps).
+2. list_dir the relevant areas. Read existing patterns — match them unless there's a reason not to.
+3. Decide: extend existing code or add new module. Justify.
+4. Sketch the data flow: inputs → transforms → outputs → side effects.
+5. Identify integration points: DB schema, API surface, env vars, container boundaries.
+6. List failure modes and how the design handles them.
+
+Rules:
+- Reuse before inventing. If a service/lib in the repo already does this, say so.
+- Prefer boring tech. New deps require justification.
+- Tailscale IPs for internal routing. No 0.0.0.0 binds.
+- Least privilege: separate read/write paths, explicit auth gates.
+- State assumptions inline. Do not ask clarifying questions mid-design unless blocked.
+
+Output:
+- Goal
+- Existing code to reuse: <file paths>
+- New code: <file paths, one-line purpose each>
+- Data model changes: <SQL or schema diff>
+- API surface: <endpoints, request/response shapes>
+- Failure modes: <list>
+- Build order: numbered, each step 30-90 min
+
+
+## Security Auditor
+---
+temperature: 0.2
+description: Audits code for security vulnerabilities. Read-only.
+---
+You audit for security issues. Concrete findings only, no generic warnings.
+
+Process:
+1. Identify the trust boundary: where does untrusted input enter? Where does it leave?
+2. Trace input flow with grep. Mark every transformation.
+3. Check each finding against a real attack scenario.
+
+Look for:
+- Injection: SQL (raw queries, string concat into queries), command (subprocess with shell=True, unescaped args), XSS (unescaped output in HTML/JSX), template injection, NoSQL injection
+- AuthN/AuthZ: missing checks on routes, IDOR (user-supplied IDs without ownership check), JWT misuse (alg=none, weak secret, no expiry), session fixation
+- Secrets: hardcoded keys/passwords, .env in repo, secrets in logs, secrets in error messages
+- Crypto: weak hashes (MD5, SHA1 for passwords), missing salt, predictable randomness (Math.random for tokens), ECB mode, custom crypto
+- Network: SSRF (user URL → server fetch), open CORS, missing CSRF on state-changing requests, plaintext over public network
+- File: path traversal, unrestricted upload type/size, zip slip
+- Deserialization: pickle, yaml.load, eval, exec on user input
+- Resource: missing rate limits on auth/expensive endpoints, unbounded query results
+
+For each finding:
+- Severity: Critical / High / Medium / Low
+- Location: file:line
+- Attack scenario: one sentence describing how an attacker exploits this
+- Fix: minimal change
+
+Skip:
+- Generic "use HTTPS" advice
+- "Consider adding rate limiting" without a specific endpoint
+- CVE-of-the-week scares without proof the code is affected
+
+If the code is clean, say so. Do not invent findings.
+
+
+## Prompt Builder
+---
+temperature: 0.4
+description: Builds prompts for OpenCode, Claude Code, or BooCode dispatch.
+---
+You write prompts that another coding agent will execute. Your output is the prompt, not the work.
+
+Process:
+1. Ask the user (or read context) for: goal, target repo, target files if known, constraints.
+2. list_dir and view_file the target area. Confirm files exist and are roughly the shape you think.
+3. Identify imports, exports, and conventions in the repo (component layout, error handling style, test framework).
+4. Write the prompt.
+
+Prompt structure:
+- One-line goal at the top
+- Constraints block: don't commit, don't push, don't pull. Use `#careful` and `#nofluff` style hashtags if the target agent honors them
+- Pre-flight: list_dir or grep commands the agent must run before writing (e.g. "run: ls frontend/src/components/ui/ and only import primitives that exist")
+- Files to modify: explicit paths
+- Files to create: explicit paths with one-line purpose
+- Behavior spec: numbered, testable
+- Backup rule: `cp file file.bak-$(date +%Y%m%d)` before any destructive edit
+- Verification: `py_compile`, `tsc --noEmit`, `docker compose up --build -d` — whichever applies
+- Stop conditions: when to halt and report instead of pressing on
+
+Rules:
+- Tailored to the target agent: OpenCode honors hashtag snippets and skills; Claude Code honors CLAUDE.md and slash commands; BooCode batches are written as user-facing markdown
+- Never include credentials or secrets
+- Never instruct the agent to commit or push
+- Include the exact model the user wants if dispatch is via Paseo or BooCode batch
+- For BooLab frontend prompts, always include the "verify shadcn primitives exist" preflight
+
+Output: the prompt, ready to paste. Nothing else.

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What is BooCode
+
+Self-hosted single-user developer chat app. AI assistant with read-only file tools (view_file, list_dir, grep, find_files) running against a local llama-swap inference server. Sessions organized by project, with a multi-pane workspace (chat + file browser side by side).
+
+Plus `apps/booterm` (second container, port 9501, bookworm-slim+glibc): Fastify + node-pty + tmux. Browser terminal panes WS to `/ws/term/sessions/:sid/panes/:pid`; per-session tmux session `bc-<sid>`, per-pane window `term-<pid>`. Shells drop privs to samkintop via `gosu` in `tmux.conf` default-command.
+
+## Commands
+
+```bash
+# Development (run in separate terminals)
+pnpm dev:server          # tsx watch, port 3000
+pnpm dev:web             # Vite dev server, port 5173 (proxies /api to :3000)
+
+# Build
+pnpm build               # builds web then server
+pnpm -C apps/server build  # server only (tsc + copy schema.sql)
+pnpm -C apps/web build     # web only (vite)
+
+# Type checking (no emit)
+npx tsc --noEmit                              # project references (root)
+npx tsc -p apps/web/tsconfig.app.json --noEmit  # web app specifically
+
+# IMPORTANT: root tsc --noEmit uses project references and can miss errors
+# that the per-app tsconfig catches. Always verify with the per-app command
+# when editing web code. The server build (pnpm -C apps/server build) is
+# authoritative for server code.
+
+# Production
+docker compose build --no-cache boocode && docker compose up -d
+```
+
+Tests: `pnpm -C apps/server test` runs 23 vitest tests. No test harness on `apps/web` (adding it requires installing vitest as a new devDep). Vitest pinned to `^3` because Vite 5 / vitest 4 are incompatible. No linters configured.
+
+## Architecture
+
+**Monorepo**: pnpm workspaces with `apps/server` (Fastify + postgres), `apps/web` (React + Vite), and `apps/booterm` (Fastify + node-pty + tmux).
+
+### Server (`apps/server/src/`)
+
+- **Fastify** with `@fastify/websocket` and `@fastify/static` (serves built frontend)
+- **postgres** (porsager/postgres) with tagged-template SQL — no ORM. Schema in `schema.sql`, applied on startup. LSP may false-positive on `sql<Type[]>\`...\`` generics; CLI `tsc` / `pnpm build` is authoritative.
+- **Zod** for request validation and config parsing.
+
+Key services:
+- **`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.
+- **`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/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.
+
+Route registration: all routes registered in `index.ts` via `register*Routes(app, sql, ...)` functions. Routes are in `routes/*.ts`.
+
+### Frontend (`apps/web/src/`)
+
+- **React 18** + React Router v6 + **Tailwind v4** + shadcn/radix-ui primitives.
+- **Shiki** for syntax highlighting (async `codeToHtml` in `CodeBlock.tsx` and `FileViewer` in `FileBrowserPane.tsx`).
+- Path alias: `@/` maps to `src/`.
+- **Mobile interaction primitives** (post-v1.6): `useViewport` (matchMedia, breakpoints mobile <768 / tablet 768–1023 / desktop ≥1024), `useSidebarDrawer` / `useRightRailDrawer` (Context + auto-close on `useLocation().pathname` change), `useLongPress` (500ms timer, dispatches synthetic `contextmenu` on `[data-tab-id]`), `usePullToRefresh` (80px threshold, 600ms hold), `SwipeablePaneTab` (60px close, 30px vertical bail). Tap-target convention: `max-md:min-h-[44px] max-md:min-w-[44px]`. Mobile headers: `border-b px-3 sm:px-4 py-2` + `style={{ paddingTop: 'max(0.5rem, env(safe-area-inset-top))' }}`. Hamburger left, FolderTree right.
+
+Key patterns:
+- **`hooks/sessionEvents.ts`** — Module-singleton event bus (Set of listeners). Used for cross-component communication: session renames, file-open events, attachment dispatch. 9 event types in the discriminated union. When adding a new event type to the `SessionEvent` union, you must also add a case to the `applyEvent` switch in `useSidebar.ts` (even if it's a no-op `return prev`).
+- **`hooks/useSessionStream.ts`** — WebSocket per session, `applyFrame` reducer builds message list from streaming frames.
+- **`hooks/useUserEvents.ts`** — Single app-level WS to `/api/ws/user` with exponential backoff reconnect. Forwards frames onto the sessionEvents bus.
+- **`hooks/useSidebar.ts`** — Module-singleton with Set<setState> subscriber pattern; one bus subscription guarded by `globalThis.__boocode_sidebar_subscribed` for HMR safety. Every new `SessionEvent` type needs a `case` in the `applyEvent` switch (no-op `return prev` is fine).
+- **`api/client.ts`** — Centralized typed fetch wrapper. All endpoints under `api.*` namespace.
+
+Font / CSS pipeline (apps/web):
+- Tailwind v4's `@import "tailwindcss"` directive strips font URLs from subsequent CSS `@import`s — `@fontsource*` packages must be imported as JS side-effect modules in `apps/web/src/main.tsx`, not via `@import` in `globals.css`. Otherwise the woff2 files never make it to `dist/`.
+- Lightning CSS (inside `@tailwindcss/postcss` v4) collapses contiguous unicode-ranges to wildcard shorthand (`U+0000-FFFF` → `U+????`), which iOS Safari/Vivaldi mishandles (silently drops the font from those codepoints). Use explicit non-wildcard-collapsible subranges (e.g. `U+2500-259F` not `U+2500-25FF`). The `apps/web` build script greps `dist/assets/*.css` for `U+2500-259F` and fails the build if missing — preserve that guard.
+- `@font-face` blocks must live AFTER all `@import` statements (CSS spec). Earlier placement silently breaks every subsequent `@import` (this broke the 18 theme palette imports in globals.css for one session).
+- JetBrainsMono Nerd Font self-hosted in `apps/web/src/fonts/` (TTF from ryanoasis/nerd-fonts release) — needed because `@fontsource-variable/jetbrains-mono` ships subsetted woff2s that don't cover `U+2500-259F` (box drawing + block elements, used by opencode's banner). "NL" = No Ligatures (matches `font-feature-settings: "liga" 0`); "Mono" = single-cell icon width so TUI layouts don't desync.
+- xterm-addon-webgl rasterizes glyphs via Canvas2D into a GPU texture atlas. Canvas2D does NOT honor `font-display: block` — it uses whatever font is currently registered. Gate xterm initialization on `document.fonts.load(<font-name>)` resolving before calling `term.open()` (see `fontsReady` useState in `TerminalPane.tsx`). iOS Safari/Vivaldi also reclaims WebGL contexts from backgrounded tabs: keep `webgl.onContextLoss(() => webgl.dispose())` + recreate via visibilitychange. Do NOT manually dispose+recreate the addon after font load — iOS silently fails the second GL context creation and the terminal drops to DOM renderer with stale metrics.
+
+### Data flow for chat
+
+1. User sends message → POST `/api/sessions/:id/messages` creates user + assistant (status=streaming) rows
+2. `inference.enqueue()` starts async streaming loop
+3. LLM deltas published via `broker.publish(sessionId, frame)`
+4. Client's `useSessionStream` WS receives frames, `applyFrame` reducer updates message list
+5. Tool calls: inference executes tools server-side, publishes tool_call/tool_result frames, loops back to LLM
+6. Terminal states (complete/error): DB updated with final content + token counts, `session_updated` frame published on user channel
+
+### Multi-pane workspace
+
+Sessions hold 1–5 panes (chat / empty / placeholder terminal+agent). Workspace pane state is **client-side only** (localStorage key `boocode.workspace.panes.<sessionId>`); the legacy `session_panes` table and its REST endpoints are deprecated — no `/api/panes/*` routes exist. Each chat lives in at most one pane; tab strip is per-pane and tracks `chatIds[]` + `activeChatIdx`. Sessions 1:N chats; chats own messages. Tab reorder via native HTML5 drag events.
+
+## Database
+
+PostgreSQL 16. Tables: `projects`, `sessions`, `chats`, `messages`, `settings`, `session_panes` (deprecated). Schema applied idempotently on startup via `applySchema()`. Use `clock_timestamp()` (not `NOW()`) inside transactions. CHECK constraints in place: `projects_status_chk` ('open'|'archived'), `sessions_status_chk` (same), `chats_status_chk` (same), `messages_role_chk`, `messages_status_chk` — keep in sync with the `*_STATUSES` const arrays in `apps/server/src/types/api.ts`.
+
+Schema CHECK migration order when renaming allowed values: (1) `ALTER TABLE ... DROP CONSTRAINT IF EXISTS <system_name>` (inline `CREATE TABLE` checks get `<table>_<column>_check`), (2) `UPDATE` rows to new values, (3) wrap new constraint ADD in `DO $$ ... pg_constraint` guard — that block is the only way to get `ADD CONSTRAINT IF NOT EXISTS`.
+
+Position-shift pattern for panes (legacy `session_panes` table): negate-and-restore to avoid UNIQUE(session_id, position) collisions during reorder/insert/delete. Sentinel value -100 for the moving pane.
+
+## Environment
+
+Required: `DATABASE_URL`, `LLAMA_SWAP_URL`. Optional: `PORT` (3000), `HOST` (0.0.0.0), `PROJECT_ROOT_WHITELIST` (/opt, read-only scope for add-existing path resolution), `BOOTSTRAP_ROOT` (/opt/projects, writable scope for create-new-project bootstrap mkdir target — host must `mkdir -p /opt/projects` before container start), `DEFAULT_MODEL`, `LOG_LEVEL`.
+
+## Workflow
+
+- Sam reviews all diffs and commits manually. Do not commit unless explicitly asked.
+- Deploy: `cd /opt/boocode && docker compose up --build -d` (or `docker compose build --no-cache boocode && docker compose up -d` if you suspect a layer-cache issue).
+- Git push to Gitea: `GIT_SSH_COMMAND="ssh -i /opt/boocode/secrets/boocode_gitea -o IdentitiesOnly=yes" git push origin <branch>`. The default agent identity is rejected; the in-repo deploy key (`secrets/`, gitignored) is the working one. Transient `Connection reset by peer` retries cleanly after `sleep 5`.
+- Don't accumulate `.bak-*` files. Clean them up in the same batch or immediately after merge.
+- Fastify global JSON parser tolerates empty bodies (overridden in `index.ts`); bodyless POSTs (archive, unarchive, stop) work without setting `Content-Type` tricks on the client.
+- Event dedup discipline: for any mutation the server publishes via `broker.publishUser`, do NOT add a local `sessionEvents.emit(...)` after the API call — `useUserEvents` forwards the WS frame onto the bus. Frontend mutation handlers must be idempotent (dedup by id, no-op on already-present).
+- `node:20-*` base images ship a `node` user at uid/gid 1000 — delete it (`userdel`/`groupdel` on debian, `deluser`/`delgroup` on alpine) before adding samkintop at 1000.
+- node-pty's compiled `.node` is libc-specific: proddeps and runtime Dockerfile stages must share libc (alpine↔musl or bookworm-slim↔glibc); the TS-only builder stage can stay alpine for speed.
+- pnpm 10 `--frozen-lockfile` skips node-pty's postinstall — the Docker proddeps stage runs `cd node_modules/node-pty && npm run install` to force the native compile.
+- A local PreToolUse hook (`security_reminder_hook.py`) regex-flags Node's older `child_process` spawn helpers as unsafe (false positive even on the File-suffixed variant). Use `spawn` — it's accepted.
+- `/opt/boolab` hosts a working sibling BooCode terminal at `boocode.indifferentketchup.com`. Useful for visual side-by-side comparison on the same iPhone when debugging booterm rendering. Boolab uses Tailwind v3 (`@tailwind base`); boocode uses v4 — many subtle build differences. Don't assume parity.
+- booterm SSHs to the host as `samkintop@100.114.205.53` (the Tailscale IP). The hostname `ubuntu-homelab` (shown in the bash prompt after login) does NOT resolve from inside the container — only the host's `/etc/hosts` knows it. Override via `BOOTERM_SSH_HOST` / `BOOTERM_SSH_USER` env vars in docker-compose if you ever move the shell to a different machine.
+
+## Conventions
+
+- `overflowWrap` not `wordWrap` — TypeScript's CSSStyleDeclaration marks `wordWrap` as deprecated (error 6385).
+- No app-layer auth. Authelia handles auth at the reverse proxy. All `broker.publishUser`/`subscribeUser` calls use `'default'` as the user key.
+- TypeScript strict mode. Both apps share `tsconfig.base.json`.
+- Server uses NodeNext module resolution (`.js` extensions in imports).
+- Discriminated unions for type narrowing: `Pane` (by `kind`), `SessionEvent` (by `type`), `InferenceFrame` (by `type`).
+- shadcn primitives live in `components/ui/`. Don't modify them unless adding a new primitive.
+- `inferLanguage()` from `lib/attachments.ts` is the canonical file-extension-to-language map. `CodeBlock.tsx` keeps its own `LANG_MAP` because it also resolves markdown fence names.
+- Two UI event buses: `hooks/sessionEvents.ts` for DB-state events (chat_created, session_updated); `lib/events.ts` for ephemeral UI (`sendToTerminal`, `terminalsRegistry`). Don't merge — different subscriber lifecycles.
+- `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.

+//   - Operates per-chat (chats have N:1 to sessions; history is per-chat).
+//   - Detects overflow automatically after each inference completion using

+//     summary=true assistant row. Older messages get compacted_at-stamped so
+//     inference assembly filters them out; the GET endpoint still returns
+//     them so the UI can show history with the summary card inline.
+//   - The summary is *anchored rolling* — exactly one live summary=true row
+//     per chat. Subsequent compactions read the prior summary as
+//     previousSummary, ask the LLM to update-merge it, then mark the prior
+//     summary row compacted_at too (it stays in the UI but isn't sent to the
