 # Commit Convention
 Gunakan **Conventional Commits** untuk semua commit. Format:
 ```
 <type>(<scope>): <description>
 ```
 **Type & efek ke versi:**
 | Type        | Bump  | Kapan pakai                              |
 |-------------|-------|------------------------------------------|
 | `feat`      | minor | Fitur baru                               |
 | `fix`       | patch | Perbaikan bug                            |
 | `chore`     | patch | Maintenance, update deps, dll            |
 | `docs`      | patch | Perubahan dokumentasi/comment            |
 | `refactor`  | patch | Refactor kode tanpa perubahan fungsional |
 | `test`      | patch | Nambah/ubah test                         |

 | `ci`        | patch | Perubahan CI/CD                          |
 **Catatan:**
 - **Semua type menghasilkan release** (patch minimal). Tidak ada commit yang "skip release".
 - Tambahkan `BREAKING CHANGE:` di body commit untuk bump **major**.
 - **Scope** opsional, tapi direkomendasikan (misal `feat(agent):`, `fix(ipc):`).
 ### Contoh
 ```
 feat(tool): add batch file delete
 chore: bump reqwest to 0.12
 refactor(harness): flatten guard pipeline
 fix(ipc): reconnect loop on socket timeout
 docs: add architecture diagram to README
 BREAKING CHANGE: IPC frame header changed from 4-byte to 8-byte length

 Test modules are located inline in production files (not a separate `tests/` dir):
 - `src/app/harness.rs` — guard/verdict parsing tests
 - `src/app/runtime/stream/mod.rs` — SSE parser tests
 - `src/model/memory.rs` — memory CRUD + slugify tests
 - `src/model/editlog.rs` — edit log append/reload tests
 - `src/tool/fs/helpers.rs` — tool argument extraction tests
 Tests use `#[cfg(test)] mod tests` blocks. There are 37 unit tests total.
 Tracing output goes to `~/.local/share/zesdex/zesdex.log`. Set `RUST_LOG=debug` for verbose logging.

 - **Single-process** (default): TUI + agent loop in one process

 - **Attach** (`--attach <id>`): TUI-only client that connects to a daemon

 - **Tools** — `trait Tool { fn name() -> &str, fn run() -> Result<String> }`, 28 impls, gated by `Harness`.
 - **Shell safety** — `tool/shell_filter/` blocks credential leaks and destructive git commands.
-### Company Pipeline (Division Architecture)
+### Hive-Mind Orchestration (Machine Intelligence)
- **5 divisions** in `src/app/subagent/division.rs`: Strategy, Engineering, Quality, Security, Documentation.
+- **A single Core Intelligence spawning anonymous processing nodes.** The Core Intelligence (main agent) compiles a cognitive cycle plan per task: an ordered list of cycles, each cycle a set of processing nodes that run in parallel. Each node's sole identity is its directive (what to do) and an access tier. Cycle count and nodes-per-cycle are entirely Core-Intelligence output.
- **Pipeline orchestrator** in `src/app/workflow/company.rs`: two modes:
+- **Access tiers** in `src/app/subagent/division.rs` (`tool_scope` module): tool access is granted per node via one of three tiers (`read` / `write` / `full`, see `tool_scope::tools_for`) picked by the Core Intelligence based on what each node's directive actually needs.
-  - `run_company_pipeline()` — full 5-division pipeline
+- **Orchestrator** in `src/app/workflow/hive_mind.rs`: `run_hive_mind()` executes a `CognitiveCyclePlan { cycles: Vec<Vec<NodeDirective>> }` cycle-by-cycle. Node IDs are system-assigned coordinates (e.g. `"Node-0-1"`).
-  - `run_company_pipeline_quick()` — 3-division (Strategy → Engineering → Quality)
+- **Continuous collective state, not phase-boundary sync**: `engine::execute_primitive`'s `ScopedAgent` arm merges each node's complete output into the shared collective-state channel the instant that node finishes — not after its whole parallel cohort completes — so sibling/later nodes see it in real time.
- **Auto-CEO trigger** in `run_agent_turn()` (`actions/mod.rs`): detects complex requests via `is_complex_request()` heuristics, auto-delegates to pipeline.
+- **Consensus synthesis, not a per-node summary**: after all cycles complete, `synthesize_consensus()` spawns one final read-only node whose sole directive is to reconcile the entire collective state into a single consensus assessment — a real reasoning pass, not string concatenation, since node outputs can overlap or conflict.
- **Override** via `/pipeline full|quick|skip` sets `MiscState::pipeline_override`, consumed on next turn.
+- **Auto-trigger** in `run_agent_turn()` (`actions/mod.rs`): `is_complex_request()` heuristics decide only whether to ask the Core Intelligence to compile a plan at all — the plan's shape is fully dynamic.
- **Live division progress** in TUI panel (`view/workflow.rs`): shows division name + current tool via `AgentStatus::progress`.
+- **`hive_mind` tool** (`src/tool/workflow.rs`) is the manual entry point: the calling LLM supplies its own `cycles` array of `{directive, access}` directly.
 - **Guaranteed documentation**: after every convergence, `src/app/workflow/docs.rs::write_hive_mind_convergence()` deterministically (not an LLM step, not skippable) writes every node's full output plus the final consensus to `docs/runs/<timestamp>-<slug>.md`.
 - **Live node progress** in TUI panel (`view/workflow.rs`): shows node designation + current tool via `AgentStatus::progress`.
 - **Auto inline review** after each edit: `src/app/subagent/auto.rs` — `spawn_quick_review()` injects verdict back into LLM conversation.
- **Background subagents** (test-gen, arch-review, security-review) fire asynchronously at turn end via `TurnEvent::SystemNote`.
+- **Background subagents** (test-gen, arch-review, security-review) fire asynchronously at turn end via `TurnEvent::SystemNote`, retrying once on failure and escalating to a blocking (`ESCALATED:`-prefixed, `ToastKind::Error`) notice if the retry also fails.

 | `ci`        | patch | Perubahan CI/CD                          |
 **Catatan:**
 - **Semua type menghasilkan release** (patch minimal). Tidak ada commit yang "skip release".
 - Tambahkan `BREAKING CHANGE:` di body commit untuk bump **major**.
 - **Scope** opsional, tapi direkomendasikan (misal `feat(agent):`, `fix(ipc):`).
 ### Contoh
 ```
 feat(tool): add batch file delete
 chore: bump reqwest to 0.12
 refactor(harness): flatten guard pipeline
 fix(ipc): reconnect loop on socket timeout
 docs: add architecture diagram to README
 BREAKING CHANGE: IPC frame header changed from 4-byte to 8-byte length

 # Backend / Service Layer
 ## AI Provider
 `src/service/provider.rs` (258 lines)
 - `LlmClient::new(api_key, model, base_url)` — constructs blocking reqwest client
 - `chat_with_tools()` — non-streaming with tool definitions
 - `chat_stream()` — SSE streaming, returns `SseParser` yielding `StreamEvent`
 - Retry logic: up to 3 attempts on transient errors, exponential backoff
 ## OAuth
 `src/service/oauth/manager.rs` (113 lines) + `loopback.rs` + `pkce.rs`
 - PKCE flow: `CodeVerifier` → challenge → browser auth → loopback server → token exchange
 - Configurable via `app_config.json` provider definitions (auth URL, token URL, scopes)
 ## IPC / Daemon
 `src/ipc/` (7 files, ~300 lines total)
 - Unix domain socket, length-prefixed JSON frames
 - Daemon sends `DaemonFrame { state: StatePayload, diff, tasks }` to clients
 - Clients send `ClientRequest { action: Action }` back
 - State sync uses snapshots + binary diffs (rsync-style, not git)
 ## Workflow Engine
 `src/app/workflow/engine.rs` (251 lines) + `script.rs`
 - Inline JS-style DSL executed by a lightweight runtime
 - `agent()`, `parallel()`, `pipeline()`, `phase()`, `log()` — spawns sub-agents
 - Max concurrency configurable via `workflow_max_concurrency` setting
 ## Sub-Agent System
 `src/app/subagent/` (4 files, ~250 lines)
 - `run_subagent()` — spawns independent agent with its own tool set & context
 - Communicates via `mpsc<SubagentEvent>` channel (tool calls, results, completion)
 - Uses `LlmClient` (same as main agent) with tool-use API
 ## MCP Client
 `src/app/mcp/manager.rs` (371 lines)
 - Stdio transport: spawns child process, JSON-RPC via stdin/stdout
 - HTTP transport: streaming HTTP with JSON-RPC
 - Tool registration: `tools/list` → `McpToolAdapter` implements `crate::tool::Tool`
 - Persistent child handle for stdio (reuses connection across calls)
 ## Self-Review
 `src/app/review/mod.rs` (437 lines)
 - Post-tool execution quality check against learned lessons
 - Invokes `run_subagent()` with reviewer prompt
 - Staleness detection: skips review after N consecutive empty results
 ## Background Bash
 `src/app/bgbash/` (2 files)
 - `spawn_bash_job()` — runs `sh -c` in a thread, collects stdout line-by-line
 - Channels: output via `mpsc<String>`, PID via `mpsc<u32>`
 - Killable via PID
 ## Gate Guard / Harness
 `src/app/harness.rs` (127 lines)
 - `Harness::gate_tool_call()` — verdict-based tool gating (allow/block)
 - Parses LLM verdicts (JSON or plain-text)

 # TUI Overhaul — Design
 **Status:** Approved, pending implementation plan
 **Date:** 2026-07-14
 **Scope:** `src/view/`, `src/controller/` (render/interaction layer only)
 ## Context
 The TUI went through a "modern design" pass the day before this spec (commit `3f5f27c`:
 dark palette, neon accents, message cards, segmented status bar). The request for this
 overhaul covers all three axes at once: aesthetics, UX/navigation, and layout paradigm —
 not a re-skin of the existing structure.
 ## Goals
 - Replace the current 3-zone layout (chat / input / status, everything else as a
  full-block centered modal) with a **Multi-Pane Dashboard**: chat stays central, a
  persistent right sidebar surfaces live status that today requires opening a modal.
 - Replace the current "neon dusk" palette with a **Tokyo Night** palette.
 - Replace the current per-message card rendering (badge pill, left accent bar, blank-line
  gaps) with a **tight inline log** format.
 - Drop decorative emoji from overlay titles in favor of plain colored text — the accent
  border/text color already carries identity.
 - Restyle (not restructure) the overlays that stay modal.
 ## Non-goals
 - No `AppStateRest` shape changes, no new `Action` variants, no controller/state-mutation
  changes. This is a view-layer repaint; `theme.rs` constants are the only "API" the rest
  of the app depends on, and their names don't change, only their values.
 - No new keybindings and no mouse support. Sidebar widgets are read-only/glanceable —
  none of the three (Workflow, Todo, Usage) are interactive today, so they don't need
  focus or selection state in their new form either.
 - No overlay is removed. Workflow/Todo/Usage keep their existing overlay trigger as an
  "expand" view (see below); the other 13 overlays are untouched functionally.
 - No automated visual/snapshot tests are being introduced (none exist today for
  `view/`/`controller/`; see Testing below).

 ```
 - The sidebar is a fixed-width column (generalizing the existing `show_todo`
  two-column split in `view/mod.rs::draw`) holding three stacked widgets, in this
  order: **Workflow**, **Tasks**, **Usage**.
 - **Responsive collapse**: below a width threshold (~90 cols — extending the existing
  `show_todo && area.width > 60` precedent, widened because the new sidebar holds three
  stacked widgets instead of one), the sidebar doesn't render and chat takes full width.
  No manual toggle key — purely width-driven, matching current behavior.
 - Each sidebar widget truncates its content to what fits and shows a `+N more, press
  <key> to expand` hint (same pattern `Rewind` already uses for `"... and N more
  messages"`) when there's more than fits — that's what the kept overlay is for.
 ### Workflow / Todo / Usage: sidebar glance + overlay expand
 These three overlays are **not removed**. Their existing trigger (same keys/commands as
 today) still opens the full-screen version — now serving as the "expand" view for when
 the sidebar column is too narrow to show everything (many hive-mind nodes, a long task
 list). The sidebar widget and the overlay both read the same state
 (`workflow_engine`, `misc.todo_content`, `session_runtime.usage` +
 `session_runtime.session_start`); the sidebar version is a new compact rendering, factored
 out so both call sites share it where the content is identical (e.g. per-agent card
 formatting in `workflow.rs`).
 ### Remaining 13 overlays: restyled modals, unchanged behavior
 `Help, Settings, Bash, QuitConfirm, KeyInput, Editor, Effort, Mcp, Rewind, Learning,
 Loading, ModelSelector, ClearConfirm` keep their current centered-modal mechanic and
 content logic exactly as-is. Only their chrome changes: new palette values (same
 semantic-color-per-overlay mapping as today — e.g. `QuitConfirm` stays `ERROR`, `Settings`
 stays `PRIMARY`), and emoji dropped from their title strings.
 ## Visual language
 ### Palette — Tokyo Night
 Values only; `Theme` constant names in `view/theme.rs` are unchanged, so every call site
 across `view/*` keeps working without edits beyond the const definitions themselves.
 | Constant | Value | Constant | Value |
 |---|---|---|---|
 | `BG` | `#1a1b26` | `ROLE_USER` | `#9ece6a` |
 | `SURFACE` | `#1f2335` | `ROLE_ASSISTANT` | `#7aa2f7` |
 | `SURFACE_ELEVATED` | `#292e42` | `ROLE_SYSTEM` | `#7dcfff` |
 | `TEXT` | `#c0caf5` | `ROLE_TOOL` | `#e0af68` |
 | `TEXT_MUTED` | `#a9b1d6` | `PRIMARY` | `#7aa2f7` |
 | `TEXT_DIM` | `#565f89` | `SUCCESS` | `#9ece6a` |
 | `BORDER` | `#3b4261` | `WARNING` | `#e0af68` |
 | `BORDER_FOCUS` | `#7aa2f7` | `ERROR` | `#f7768e` |
 | `HIGHLIGHT` | `#3d59a1` | `INFO` | `#7dcfff` |
 | `HIGHLIGHT_DIM` | `#292e42` | `ACCENT_PURPLE` | `#bb9af7` |
 | `STATUS_BAR_BG` | `#16161e` | `ACCENT_PINK` | `#ff007c` |
 | `MODE_AUTO` | `#9ece6a` | `ACCENT_ORANGE` | `#ff9e64` |
 | `MODE_YOLO` | `#f7768e` | `ACCENT_TEAL` | `#73daca` |
 | `CODE_BG` | `#16161e` | `CODE_BAR` | `#292e42` |
 | `BLOCKQUOTE_BAR` | `#7dcfff` | `SCROLLBAR_BG` / `SCROLLBAR_FG` | `#1f2335` / `#3b4261` |
 ### Message density — tight inline log
 Replaces the per-message card (role badge pill + left accent bar + blank-line gap)
 in `chat.rs`:
 ```
 you 09:14  fix the login bug
 ai  09:14  Looking at src/auth.rs now.
   ↳ Reading src/auth.rs
 you 09:15  ok try again
 ```
 - Role rendered as a short lowercase colored label (`ROLE_*` colors), timestamp dim,
  inline with the first content line.
 - Wrapped/multi-line content aligns under the content column (not under the role label).
 - Tool-call sub-lines get a dim `↳` prefix.
 - No blank line within a turn; a single blank line only between different speakers (not
  after every message).
 - The chat panel's outer bordered `Block` is unchanged — only the messages inside it lose
  per-message decoration.
 - The streaming indicator becomes `ai 09:14  ⠋ generating...` inline, matching the new
  format, instead of the current padded badge line.
 ### Icons
 Overlay titles drop decorative emoji (❓⚙💻🚪✏️🎯🔌📋⏪📚📊⏳🧠🗑️⚡) and render as plain
 bold colored text (e.g. `Settings` in `PRIMARY`, no ⚙). The border/text accent color is
 the identity signal, consistent with the muted Tokyo Night + tight-density direction.
 ## File impact
 | File | Change |
 |---|---|
 | `view/theme.rs` | Palette values swap (table above). Const names/count unchanged. |
 | `view/chat.rs` | Rewrite message rendering to the tight inline format. |
 | `view/markdown.rs` | Re-themed code/quote colors; tightened padding. No structural rewrite. |
 | `view/mod.rs` | `draw()` grows the persistent sidebar column (generalizes `show_todo` split). `render_overlay()` match arms restyled in place (palette + title text), content logic untouched. Todo/Usage compact-widget rendering factored out of the current inline overlay code so it's callable from both the sidebar and the kept overlay. |
 | `view/status.rs` | Restyle to new palette; structurally unchanged. |
 | `view/workflow.rs` | Add a compact-card render function for the sidebar widget, reusing the existing per-agent formatting logic. |
 | `controller/*` | No changes. Interaction model is unchanged; sidebar is non-interactive. |
 ## Edge cases
 - Empty states per sidebar widget (no workflow running, no tasks, zero usage) — compact
  one-line placeholders, consistent with the tight density (not the current multi-line
  placeholder paragraphs).
 - Sidebar auto-collapses below ~90 cols; chat reclaims full width.
 - Sidebar widget overflow (e.g. a hive-mind run with many nodes, a long task list)
  truncates with a `+N more` hint pointing at the existing expand-overlay trigger.
 - Long chat content wraps with continuation lines aligned under the content column.
 ## Testing / verification
 No automated visual or snapshot tests exist for `view/`/`controller/` today (confirmed:
 zero `#[cfg(test)] mod tests` in either directory), and none are introduced by this
 change — ratatui rendering isn't meaningfully unit-testable without a snapshot harness
 this repo doesn't have. Verification is manual: run the TUI (`cargo run`) and exercise
 the golden paths (send a chat message, trigger a workflow/hive-mind run, open each of the
 13 remaining overlays, resize the terminal across the sidebar-collapse threshold).
 `cargo clippy` must stay clean (warnings-as-errors per repo config), and every touched
 `pub fn`/`struct` keeps the doc-comment convention from CLAUDE.md (What/Flow/Why/Return).
 ## Suggested implementation order
 Not binding — the implementation plan owns sequencing — but a sensible build order given
 the dependency shape (palette first, since everything else reads `Theme` consts):
 1. `theme.rs` palette swap
 2. `chat.rs` tight-inline rewrite
 3. `mod.rs` sidebar scaffolding + Workflow/Tasks/Usage compact widgets (+ `workflow.rs`
   compact-card fn)
 4. `status.rs` restyle + remaining 13 overlay restyle (mechanical: palette + title text)
 5. Manual TUI verification pass across golden paths above

 # Clipboard Copy via OSC52 — Design
 **Status:** Approved, pending implementation plan
 **Date:** 2026-07-15
 **Scope:** `src/app/state/misc.rs`, `src/controller/input.rs`, `src/main.rs`,
 `src/ipc/protocol.rs`
 ## Context
 There is no clipboard support anywhere in the TUI today, and mouse capture is enabled
 (`EnableMouseCapture` in `main.rs`), which in most terminal emulators suppresses native
 click-drag text selection unless the user holds a modifier — making an in-app copy action
 more valuable than it would be in a plain scrollback. OSC52 is a terminal escape sequence
 (`\x1b]52;c;<base64>\x07`) that asks the terminal emulator itself to set the system
 clipboard; it needs no OS-level clipboard library (no X11/Wayland/win32 dependency) and
 the `base64` crate is already a dependency (used in `service/oauth/pkce.rs`), so no new
 crate is needed for this feature.
 Key architectural constraint discovered while designing this: `controller::input::handle_key`
 runs on the **daemon** process in `--daemon`/`--attach` mode (`main.rs:359`, inside
 `handle_daemon_client`), not on the process that owns the user's actual terminal. A raw
 `io::stdout()` write inside `handle_key` would go to the headless daemon's stdout in that
 mode, not the user's terminal. The copy action therefore can't write the escape sequence
 directly from `handle_key` — it has to signal intent via state, and the terminal-owning
 process (single-process `run_loop_inner`, or the attach client's loop) performs the actual
 write.
 ## Goals
 - `Ctrl+Y` copies the most recent `Role::Assistant` message's raw text (not the rendered
  markdown spans) to the system clipboard via OSC52.
 - Works identically in single-process mode and in `--daemon`/`--attach` mode.
 - No new dependency.
 ## Non-goals
 - No native clipboard fallback (e.g. `arboard`) for terminals that don't honor OSC52 —
  unsupported terminals silently swallow the escape sequence; no error surfaces to the
  user beyond the optimistic "Copied to clipboard" toast (there's no ack mechanism in the
  OSC52 protocol to verify the terminal actually did it).
 - No copy-last-code-block variant — out of scope for this pass; the whole-message copy
  covers the common case and is simple to extend later if needed.
 - No mouse-drag text selection — unrelated, much larger feature; not being built here.
 ## State (`misc.rs`)
 - `MiscState` gains `pub pending_clipboard_copy: Option<String>`, initialized to `None` in
  `MiscState::new()`.
 ## `input.rs`
 - New top-level arm alongside the existing `Ctrl+C`/`Ctrl+D` handlers:
  `KeyCode::Char('y') if key.modifiers.contains(KeyModifiers::CONTROL)`. It finds the last
  message in `state.transcript_cache.messages` with `role == Role::Assistant`:
  - If found: `state.misc.pending_clipboard_copy = Some(msg.content.clone())`.
  - If not found: push an `Info` toast ("No assistant message to copy yet") and leave
    `pending_clipboard_copy` as `None`.
  - Returns `Vec::new()` — this is a direct state mutation inside `handle_key`, matching
    the existing `Ctrl+S` editor-save precedent (`main.rs`'s editor branch also mutates
    state/does I/O directly rather than going through an `Action`).
 ## OSC52 write helper (`main.rs`)
 ```
 fn write_osc52(stdout: &mut impl Write, text: &str) -> io::Result<()> {
    let b64 = base64::engine::general_purpose::STANDARD.encode(text);
    write!(stdout, "\x1b]52;c;{b64}\x07")?;
    stdout.flush()
 }
 ```
 Generic over `impl Write` so both the single-process loop (writing to `io::stdout()`) and
 tests (writing to a `Vec<u8>` to assert the formatted sequence) can use it without a real
 terminal.
 ## Single-process mode (`run_loop_inner`)
 After the existing `for action in actions { apply_action(state, action); }` block, add:
 ```
 if let Some(text) = state.misc.pending_clipboard_copy.take() {
    let _ = write_osc52(&mut io::stdout(), &text);
    state.push_toast(Toast::new(ToastKind::Success, "Copied to clipboard".into()));
 }
 ```
 ## Daemon/attach mode
 - `ipc/protocol.rs`: add `DaemonFrame::ClipboardCopy(String)` (alongside `StateUpdate`,
  `StreamToken`, `SystemNote`, `Closed` — same `Serialize`/`Deserialize` derive).
 - `handle_daemon_client` (`main.rs`): after each branch that calls `handle_key`/`apply_action`
  (`KeyPress` and `Submit`, the only two that can reach the input handler), before the
  existing `send_daemon_update(&mut conn, state)?;` call, add:
  ```
  if let Some(text) = state.misc.pending_clipboard_copy.take() {
      conn.send(&DaemonFrame::ClipboardCopy(text))?;
  }
  ```
 - Attach-client loop (`main.rs`, the function matching on `DaemonFrame::StateUpdate` /
  `SystemNote` / `Closed` around line 573): add a `DaemonFrame::ClipboardCopy(text) => {
  let _ = write_osc52(&mut io::stdout(), &text); client_state.push_toast(...); }` arm,
  mirroring the existing `SystemNote` handling but performing the actual terminal write
  since this process — not the daemon — owns the user's terminal.
 ## Testing
 Inline `#[cfg(test)] mod tests` per CLAUDE.md convention:
 - `input.rs`: `Ctrl+Y` with a transcript containing multiple messages sets
  `pending_clipboard_copy` to the *last* assistant message's content, ignoring later
  user/tool messages that might follow it; with no assistant message present, it pushes
  an info toast and leaves `pending_clipboard_copy` as `None`.
 - `main.rs`: `write_osc52` writing into a `Vec<u8>` buffer produces the exact expected
  `\x1b]52;c;<base64>\x07` byte sequence for a known input string.

 # Diff View for edit/write Tools — Design
 **Status:** Approved, pending implementation plan
 **Date:** 2026-07-15
 **Scope:** `src/tool/fs/edit.rs`, `src/tool/fs/write.rs`, `src/view/markdown.rs`, `src/view/chat.rs`
 ## Context
 `edit` currently reports only a byte-delta (`"edited {rel} ({N} byte delta)"`), and `write`
 reports only a byte count. Neither the model nor the user sees what actually changed —
 just a number. This makes it hard for the model to self-verify an edit landed correctly,
 and hard for the user to review a change without opening the file. No diff-computing
 library exists in the dependency tree today.
 ## Goals
 - `edit` returns a real unified diff (git-style, 3 lines of context) of the change it just
  made, in place of the byte-delta note.
 - `write` returns the same kind of diff when it overwrites a file that already existed
  with valid UTF-8 content; falls back to the current "wrote N bytes" message for new
  files or non-UTF-8 (binary) overwrites.
 - Diffs render in the chat view with real color (green add / red remove / cyan hunk
  header) instead of being flattened to dim/italic like other tool output.
 - Large diffs are truncated with a trailing count, matching the existing pattern in
  `read.rs` (`"... ({N} more lines, total {total})"`).
 ## Non-goals
 - No diff view for any tool besides `edit`/`write` (e.g. no retroactive diffing of
  `bash_tools.rs` shell edits).
 - No side-by-side diff layout — unified format only, matching how every other tool
  output already renders as a single text stream.
 - No persistence of diff history; each diff is only the delta of the single tool call
  that produced it, not a cumulative session diff.
 - No changes to non-tool (assistant/user/system) message rendering or coloring.
 ## Dependency
 Add `similar = "3"` (line/word diff crate; permissive MIT/Apache-2.0, no heavy
 transitive deps). Use `TextDiff::from_lines(old, new).unified_diff().context_radius(3)`,
 which produces standard `@@ -a,b +c,d @@` hunk headers and `-`/`+`/` `-prefixed lines —
 no custom diff algorithm needed.
 ## Tool changes
 ### `edit.rs`
 After computing `new_content` and writing it to disk:
 1. Compute `similar::TextDiff::from_lines(&content, &new_content).unified_diff().context_radius(3).to_string()`.
 2. Split into lines; if `> MAX_DIFF_LINES` (200), keep the first 200 and append
   `"... ({N} more lines truncated)"`.
 3. Wrap the (possibly truncated) diff text in a fenced ` ```diff ` block.
 4. Replace the byte-delta note in the returned message with this block; keep the
   existing "Graduated checks matched" / LSP note suffixes in their current position
   (after the diff block).
 ### `write.rs`
 Before overwriting:
 1. If `path.exists()` and `fs::read_to_string(&path)` succeeds (valid UTF-8), capture it
   as `old_content` and note `is_overwrite = true`.
 2. If the file doesn't exist, or reading it fails (binary/non-UTF-8), `is_overwrite = false`
   — no error, just skip the diff path silently.
 3. After writing, if `is_overwrite`, compute and truncate the diff exactly as in `edit.rs`
   and append the fenced block to the return message (in addition to the existing
   "wrote N bytes" line, not instead of it — for `write`, unlike `edit`, the byte count is
   still useful since it can be a full-file rewrite).
 4. If not `is_overwrite`, return message is unchanged from today.
 The truncation constant (`MAX_DIFF_LINES = 200`) and truncation message format are
 shared — factor into a small helper in `tool/fs/helpers.rs` used by both tools.
 ## Rendering changes
 ### `markdown.rs`
 - `render_markdown` gains a `dim: bool` parameter: `render_markdown(text, width, dim)`.
 - Capture the fence language from `Tag::CodeBlock(CodeBlockKind::Fenced(lang))` (today
  matched as `CodeBlock(_)`, discarding the language). Track `in_diff_block: bool` when
  `lang == "diff"`.
 - Inside a diff block, process text line-by-line instead of as one blob: a line starting
  with `+` (not `+++`) is styled green, `-` (not `---`) red, `@@` cyan/muted, everything
  else (context lines, `+++`/`---` file headers) uses the existing code-block teal.
 - When `dim` is `true`: every span keeps its assigned color as computed above, but
  non-diff spans (headings, links, plain text, non-diff code blocks, table cells) fall
  back to `Theme::TEXT_DIM` + `Modifier::ITALIC` instead of their normal palette color —
  this replicates today's "tool output is always dim" behavior for everything except
  diff lines.
 - When `dim` is `false`: behavior is unchanged from today (full color, used for
  assistant/user/system messages).
 ### `chat.rs`
 - `Role::Tool` branch: replace the two manual span-remapping loops (that force every
  span to `dim_italic`) with a direct call to `render_markdown(&content, content_width, true)`
  and use the returned spans as-is.
 - All other roles: call `render_markdown(&content_str, content_width, false)` — same
  call as today, just with the new explicit `false` argument.
 ## Testing
 Inline `#[cfg(test)] mod tests` per CLAUDE.md convention:
 - `edit.rs`: a normal single-replace edit produces a diff block with matching
  `-`/`+` lines; a `replace_all` across 250+ lines truncates at 200 with the correct
  trailing count.
 - `write.rs`: writing a brand-new file keeps the old "wrote N bytes" message with no
  diff block; overwriting an existing UTF-8 file produces a diff block; overwriting
  a path that reads as invalid UTF-8 (simulate via non-UTF-8 bytes) falls back to the
  byte-count message without erroring.
 - `markdown.rs`: a fenced ` ```diff ` block with `+`/`-`/`@@` lines produces spans with
  the expected fg colors under `dim=true` (diff lines colored) and confirms non-diff
  text in the same call falls back to `TEXT_DIM` + italic.

 # Fuzzy @file-mention Autocomplete — Design
 **Status:** Approved, pending implementation plan
 **Date:** 2026-07-15
 **Scope:** `src/app/state/misc.rs`, `src/app/state/rest.rs`, `src/controller/input.rs`,
 `src/view/mod.rs`, `src/tool/mod.rs`, `src/tool/fs/write.rs`, `src/main.rs`
 ## Context
 The chat input already has a dropdown autocomplete (`InputState` in `misc.rs`), but it
 only covers slash commands: it requires the whole buffer to start with `/` and filters a
 fixed `COMMANDS` list by prefix. There's no way to reference a project file from the chat
 input without typing its exact path from memory. The existing `dir_cache` (used by the
 `dir_cache_update` tool) looks like it could serve this but doesn't: it's a single,
 non-recursive directory snapshot, overwritten on each LLM-driven `dir_cache_update` call —
 not a standing, recursive, whole-workspace file index. `search.rs`'s `Grep`/`Glob` tools
 already do the recursive, `.gitignore`-respecting walk this feature needs, via
 `ignore::Walk`.
 Also relevant: there is no persistent async runtime driving the TUI loop. `main.rs`
 constructs a `tokio::runtime::Runtime` but never `.enter()`s or `block_on`s it in the
 main loop — `run_loop` is fully synchronous. The one existing async-flavored pattern
 (`dir_cache_update.rs`) spins up a throwaway one-shot runtime purely to satisfy
 `tokio::sync::RwLock`'s API, then discards it. This feature does not need that ceremony:
 a plain `std::sync::RwLock` is enough, since every reader/writer here is synchronous
 (`handle_key`, `Tool::run`, and the index-build thread all being plain sync code).
 ## Goals
 - Typing `@` at a word boundary (start of buffer or after whitespace) in the chat input,
  followed by non-whitespace characters, opens a dropdown of fuzzy-matched project file
  paths, live-updating as the query changes.
 - Selecting a candidate splices `@relative/path ` into the buffer at the mention's
  position (not a whole-buffer replace) and the user keeps typing.
 - Candidates come from a background-built, whole-workspace file index — not the
  LLM-facing `dir_cache`.
 ## Non-goals
 - No auto-reading of the selected file's content into the conversation — the inserted
  `@path` is plain text; the model reads it via the `read` tool if it wants to, same as
  any other path reference.
 - No live re-filter on Backspace/Delete while a mention dropdown is open — mirrors the
  slash-command dropdown's existing behavior (closes on Backspace/Delete rather than
  refiltering). Not fixing that for commands here; file mentions just inherit it for
  consistency.
 - No periodic re-walk of the index after startup — only single-file incremental updates
  on file creation (see below). A deleted or renamed file may show a stale entry until
  restart; acceptable since selecting it just inserts text, it doesn't touch the
  filesystem.
 - No fuzzy matching over directories, only files.
 ## Dependency
 Add `nucleo-matcher = "0.3"` (the fuzzy-matching engine from the Helix editor project;
 small, actively maintained, no heavy transitive deps).
 ## Index storage & construction
 - New type in `misc.rs`: `MentionIndex { entries: Arc<std::sync::RwLock<Vec<String>>> }`, with `MentionIndex::new()`, `set(&self, paths: Vec<String>)`, and `snapshot(&self) -> Vec<String>` (both plain sync `.write()`/`.read()`, no `try_`/async — a std `RwLock` doesn't block indefinitely here since every hold is a quick vec swap or clone).
 - `AppStateRest` gets a `pub mention_index: MentionIndex` field, initialized in `AppStateRest::new()`, threaded into `ToolCtx`/`ToolCtxBuilder` the same way `dir_cache` is (new `mention_index` field on both, wired through `tool_ctx()`/`tool_ctx_for()`/`build()`).
 - In `main.rs`, right after `AppStateRest::new(...)` in the single-process TUI path and the daemon path (not the attach-only client path, which has no local `ToolCtx`), spawn `std::thread::spawn` that:
  1. For each workspace root (index `i`, path `w`): `ignore::Walk::new(w)`, keep only files, strip `w` as prefix, format as `rel` for `i == 0` or `[i]rel` for `i > 0` (matching `resolve_path`'s existing workspace-index convention).
  2. Stop collecting once the total across all workspaces hits 50,000 entries (repos larger than that are rare here; this is a soft cap to bound memory/scan time, not a hard requirement).
  3. Call `mention_index.set(all_paths)`.
 - `write.rs`: after a successful write, if the target path did **not** exist before the write (i.e. this created a new file, not an overwrite), compute its relative/workspace-prefixed form and push it onto `ctx.mention_index`'s vec directly (read-modify-write under the same lock) rather than re-walking.
 ## `InputState` changes (`misc.rs`)
 - New `pub enum AutocompleteKind { Command, FileMention }`.
 - `InputState` gains `pub autocomplete_kind: AutocompleteKind` (default `Command`) and
  `pub mention_start: usize` (byte offset of the triggering `@`).
 - New `fn mention_query_at_cursor(&self) -> Option<(usize, String)>`: scans backward from
  `self.cursor` for an `@`; the scan stops (returns `None`) if it hits whitespace before
  finding `@`. The `@` only counts as a trigger if it's at buffer start or immediately
  preceded by whitespace. Returns `(byte offset of '@', query text between '@' and cursor)`.
 - New `fn open_mention_autocomplete(&mut self, files: &[String])`: calls
  `mention_query_at_cursor()`; if `None`, calls `close_autocomplete()` and returns. If
  `Some((start, query))`, fuzzy-matches `query` against `files` via `nucleo-matcher`,
  keeps the top 10 by score, sets `autocomplete_candidates`, `autocomplete_kind =
  FileMention`, `mention_start = start`, `autocomplete_visible = !candidates.is_empty()`.
 - `select_autocomplete()` becomes kind-aware:
  - `Command` (today's behavior, unchanged): `buffer = candidate.clone()`, `cursor =
    buffer.len()`.
  - `FileMention`: `buffer.replace_range(mention_start..cursor, &format!("@{candidate} "))`,
    `cursor = mention_start + candidate.len() + 2` (the `@` plus the candidate plus the
    trailing space).
  - Both paths end with `close_autocomplete()`, same as today.
 ## `input.rs` wiring
 - `KeyCode::Char(c)` handler: after `state.input.insert(c)`, keep the existing
  `if buffer.starts_with('/') { open_autocomplete() }` check, and add an `else if let
  Some(_) = state.input.mention_query_at_cursor() { state.input.open_mention_autocomplete(&state.mention_index.snapshot()) }` branch. These are mutually exclusive in practice (a
  buffer starting with `/` is a slash command, not a sentence with an `@mention` in it).
 - `KeyCode::Backspace` / `KeyCode::Delete`: unchanged — both already just call
  `close_autocomplete()` when a dropdown is visible, regardless of kind. No new branching
  needed since `close_autocomplete()` already resets `autocomplete_kind` isn't touched but
  becomes irrelevant once `autocomplete_visible` is false.
 - `KeyCode::Tab`: currently gated on `buffer.starts_with('/')`. Extend the condition to
  also fire when `autocomplete_kind == FileMention && autocomplete_visible` so Tab cycles
  file-mention candidates too.
 - `KeyCode::Enter`: unchanged — already calls `select_autocomplete()` whenever
  `autocomplete_visible`, which is now kind-aware internally.
 ## Rendering (`view/mod.rs`)
 - `render_input_bar`'s dropdown block reuses the exact same list-rendering code (already
  generic over `autocomplete_candidates`/`autocomplete_idx`); only the title changes based
  on `state.input.autocomplete_kind`: `" ⌘ Commands "` (unchanged) vs `" 📁 Files "`.
 ## Testing
 Inline `#[cfg(test)] mod tests` per CLAUDE.md convention:
 - `misc.rs`: `mention_query_at_cursor` returns the right `(start, query)` for `@` at
  buffer start, `@` after a space mid-sentence, and correctly returns `None` when the `@`
  is mid-word (e.g. `foo@bar`) or when whitespace exists between the `@` and the cursor.
  `select_autocomplete` for `FileMention` splices correctly into a buffer with text before
  and after the mention span; `Command` selection still replaces the whole buffer as
  before.
 - `write.rs`: creating a new file appends its path to the shared `mention_index`;
  overwriting an existing file does not add a duplicate entry.
 - Index construction: not unit-tested directly (it's a `std::thread::spawn` walking the
  real filesystem at startup) — covered implicitly by exercising the app manually per the
  `verify` skill during implementation.

 CRITICAL: Never ignore pre-existing errors, warnings, or technical debt. Flag them for fixing immediately. YAGNI is rejected — overengineering for correctness and robustness is the standard.
 You have read-only access to the workspace. Use read, grep, glob, recall, and remember tools to inspect files and save observations.
 Review guidelines:
 1. Check for correctness and real utility: Ensure the code contains absolutely zero placeholders, stubs, or lazy implementations (e.g., no `todo!()`, `pass`, or incomplete logic). Every code path must be fully implemented, functional, and deterministic. Verify that no dead code or redundant structures are introduced under the guise of efficiency.
 2. Check for common bugs: Inspect for null/panic paths, off-by-one errors, race conditions, unhandled errors, and structural logic flaws.
 4. Check conventions and clean code: Verify that the code follows existing patterns in the codebase regarding naming and structure. Ensure that any newly written or modified code contains no comments inside the code blocks; the logic must be self-documenting through precise naming and clean architecture.
 5. Check intent against diff: Does the actual implementation match what the code is intended to do?
 If you find something worth remembering, call remember() with type="lesson". Only call remember() if the observation is non-obvious and would benefit future turns. Skip trivial style nits.
 Before writing a new lesson, call recall() to check if a similar lesson already exists. Deduplicate — don't write the same lesson twice.
