-### Company Pipeline (Division Architecture)
+### Hive-Mind Orchestration (Machine Intelligence)
 
-- **5 divisions** in `src/app/subagent/division.rs`: Strategy, Engineering, Quality, Security, Documentation.
-- **Pipeline orchestrator** in `src/app/workflow/company.rs`: two modes:
-  - `run_company_pipeline()` — full 5-division pipeline
-  - `run_company_pipeline_quick()` — 3-division (Strategy → Engineering → Quality)
-- **Auto-CEO trigger** in `run_agent_turn()` (`actions/mod.rs`): detects complex requests via `is_complex_request()` heuristics, auto-delegates to pipeline.
-- **Override** via `/pipeline full|quick|skip` sets `MiscState::pipeline_override`, consumed on next turn.
-- **Live division progress** in TUI panel (`view/workflow.rs`): shows division name + current tool via `AgentStatus::progress`.
+- **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.
+- **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.
+- **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"`).
+- **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.
+- **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.
+- **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.
+- **`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.

 ## Process Modes
 
-| Mode | Impl | Process | IPC |
-|------|------|---------|-----|
-| Single | `run_single_process()` | One | No |
-| Daemon | `run_daemon()` | Server | `ipc/server.rs` |
-| Attach | `run_attach()` | Client | `ipc/client.rs` |
+| Mode | Description |
+|------|-------------|
+| **Single-process** | TUI + agent run in the same process. Simplest mode. |
+| **Daemon** | `--daemon` flag. Agent processes state in background; clients attach to render. |
+| **Attach** | `--attach <id>` flag. Connect to existing daemon with IPC. |
+
+In daemon mode, the daemon runs the full agent loop; clients are stateless renderers that sync via Unix domain sockets with diff-based state synchronization.
+
+## Data Flow
+
+1. **Input** → `controller/input.rs` handles key events and autocomplete
+2. **Dispatch** → `app/runtime/actions/mod.rs` applies actions to state (`AppStateRest`)
+3. **LLM Stream** → `app/runtime/stream/mod.rs` parses SSE chunks into typed events
+4. **Tool Execution** → `app/harness.rs` gates and runs tool calls via the `Tool` trait
+5. **Rendering** → `view/` modules read `AppStateRest` and render via ratatui

+- **Protocol**: `ipc/protocol.rs` defines message types (Action, StateSnapshot, etc.)
 
-`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)
+Flow:
+```
+Client ──Action──▶ Daemon ──apply_action()──▶ State mutated
+                     │
+                     └──StatePayload──▶ Client (render)
+```
 
 ## 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
+Located in `src/app/workflow/`:
 
-## Sub-Agent System
+- **Script DSL** (`engine.rs`): Executes the workflow script language (agent/parallel/pipeline/phase). Supports subagent spawning with schema-validated output, concurrency limiting, and budget tracking.
+- **Hive Mind** (`hive_mind.rs`): Core Intelligence spawns a CognitiveCyclePlan — ordered cycles of parallel processing nodes. Each node has a directive and access tier (`read`/`write`/`full`). Node outputs merge into a shared collective state in real time. Final consensus synthesis completes the convergence.
+- **Docs** (`docs.rs`): Deterministic (not LLM) convergence writer — records every node's output + final consensus to `docs/runs/`.
 
-`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 (Model Context Protocol)
 
-## MCP Client
+`src/app/mcp/manager.rs` manages MCP client connections:
 
-`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)
+- Uses the `rmcp` crate for the MCP protocol
+- Supports stdio-based transport (child process) and streamable HTTP
+- Tool discovery via `list_tools()` and dynamic tool registration
 
-## Self-Review
+## LSP Integration
 
-`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
+`src/app/lsp/` provides Language Server Protocol support:
+
+- **Auto-provisioner** (`provisioner.rs`): Detects and starts LSP servers for Rust, TypeScript, Python, Go, and other languages
+- **Client** (`client.rs`): JSON-RPC-based LSP client with typed notifications
+- **Tools** (`tool/lsp/mod.rs`): 7 LSP tools (connect, hover, completion, definition, references, diagnostics, disconnect)
 
 ## 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
+`src/app/bgbash/` manages long-running shell jobs:
 
-## Gate Guard / Harness
+- **Control** (`control.rs`): Job lifecycle management (spawn, signal, terminate) using Unix process groups
+- **Job** (`job.rs`): Individual job state tracking with output buffering and progress monitoring
 
-`src/app/harness.rs` (127 lines)
-- `Harness::gate_tool_call()` — verdict-based tool gating (allow/block)
-- Parses LLM verdicts (JSON or plain-text)
-- `test_parse_verdict_*` tests for 6 verdict formats
+## Review System
+
+`src/app/subagent/auto.rs` spawns background reviews:
+
+- Quick review after every edit
+- Background test generation
+- Architecture review  
+- Security review
+- All retry once on failure, escalate to blocking error if retry also fails

-## Key Files
+**Mutation rules** (per CLAUDE.md):
+- Mutated in-place from exactly two locations: `actions/mod.rs` (apply_action) and `controller/input.rs` (key handlers)
+- Read-only from every other module
+- No generic update function — direct field mutation only
 
-| File | Lines | Role |
-|------|-------|------|
-| `src/model/store.rs` | ~50 | File-system storage (ensure_dirs, base_dir resolution) |
-| `src/model/settings.rs` | ~60 | `Settings` — load/save JSON, API keys map |
-| `src/model/app_config.rs` | ~80 | `AppConfig` — provider definitions, model roles, auth |
-| `src/model/memory.rs` | 332 | Memory CRUD — markdown files with frontmatter |
-| `src/model/editlog.rs` | 121 | Edit log — append-only JSON array |
-| `src/model/msglog/` | 4 files | SQLite-backed message log (schema, query, blobs) |
-| `src/model/session.rs` | ~60 | Session CRUD, listing, archival |
-| `src/model/session_lock.rs` | ~50 | flock-based session lock |
-| `src/model/agent_def/` | 3 files | Agent definitions (builtin, global, session-local) |
+## Persistence
 
-## Key Patterns
+### SQLite Message Log (`src/model/msglog/`)
 
-- **No ORM** — raw JSON files + SQLite via rusqlite
-- **settings.json** — loaded at startup, saved on quit / mode switches
-- **Memory format** — Markdown files with YAML frontmatter (`---\nname: ...\ndescription: ...\n---\ncontent`)
-- **Edit log** — append-only, stores `(file, old, new, timestamp, tool)`
-- **Session locking** — flock-based, prevents concurrent access to same session dir
-- **Message log** — SQLite with attached blobs for tool arguments/outputs
+| File | Purpose |
+|------|---------|
+| `schema.rs` | Table definitions (messages, sessions) |
+| `mod.rs` | CRUD operations |
+| `query.rs` | Query helpers (search, filter) |
+| `blobs.rs` | Large message blob storage |
+| `summary.rs` | Conversation summary cache |
+
+Schema uses `rusqlite` (bundled) with per-session isolation — each session gets its own database.
+
+### Memory System (`src/model/memory.rs`)
+
+File-based memory stored under `~/.claude/projects/<project>/memory/`:
+
+- Each memory is one markdown file with frontmatter (name, description, type)
+- Types: `user`, `feedback`, `project`, `reference`
+- Memory index in MEMORY.md
+- Export/import for lesson sharing
+- PID-file session lock prevents concurrent access
+
+### Settings & Config (`src/model/`)
+
+| File | Purpose |
+|------|---------|
+| `settings.rs` | Serialized user preferences (provider, model, theme) |
+| `app_config.rs` | Provider endpoints, API key resolution from env |
+| `session.rs` | Current session metadata |
+| `conversation.rs` | In-memory conversation state |
+| `editlog.rs` | Append-only JSONL edit audit trail |
+
+### Edit Log
+
+`src/model/editlog.rs` records every file mutation:
+
+```json
+{"ts": 123, "tool": "edit", "path": "src/main.rs",
+ "reason": "fix bug", "content_sha256": "abc123",
+ "bytes_delta": 15, "origin": "chat", "session_id": "sess-1"}
+```
+
+Max 5000 entries held in memory before pruning oldest.
+
+## Context Management (`src/app/runtime/context/`)
+
+| Module | Purpose |
+|--------|---------|
+| `tokens.rs` | Token counting via `tiktoken-rs` |
+| `window.rs` | Token window resolution (fit within model context) |
+| `dedup.rs` | Deduplication of repeated tool outputs |
+| `squash.rs` | Compression of large JSON tool results |
+| `shaping.rs` | Message dropping when context exceeds limits |
+
+## IPC Data Flow
+
+```
+Daemon State ──diff──▶ serialize ──frame──▶ socket ──▶ Client
+                                                          │
+Client State ◀── apply_diff ◀── deserialize ◀──── socket ─┘

-## State Mutations
+## Input Handling
 
-State is mutated in-place from two locations:
-- `src/controller/input.rs` — keyboard shortcuts and overlay interactions
-- `src/app/runtime/actions/mod.rs` — `apply_action()` reducer for all programmatic actions
+`controller/input.rs`:
 
-## Toast Notifications
+- Normal mode: keystrokes go to the active overlay
+- `@mention` triggers fuzzy autocomplete (via `nucleo-matcher`)
+- Tab cycles autocomplete candidates
+- `Ctrl+Y` copies selected text to clipboard (via OSC52 escape sequence)
+- Arrow keys scroll chat, sidebar, and other scrollable panels
 
-`render_toasts()` — floating stack at top-right, color-coded by severity:
-- Info: blue, Success: green, Warning: yellow, Error: red, Lesson: cyan
-- Max 4 visible, auto-expire after 5s lifetime
+## Theme
+
+`view/theme.rs` defines a Tokyo Night color palette as constants (`Theme::PRIMARY`, `Theme::ERROR`, `Theme::TEXT_MUTED`, etc.) rather than using a theme enum or hot-reloadable config. All view modules import and apply these constants directly.

+# 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).
+
+## Layout architecture

+
+- 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` |

+### 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.

+# Context & Compaction Overhaul — Design
+
+**Status:** Approved, pending implementation plan
+**Date:** 2026-07-16
+**Scope:** replaces `src/app/runtime/shortsend.rs`; touches `src/app/runtime/actions/mod.rs`,
+`src/view/status.rs`, `src/model/settings.rs`, `src/app/subagent/division.rs`, `Cargo.toml`
+
+## Context
+
+The existing conversation-compaction system (`shortsend.rs`, 129 lines) only acts once the
+context is already close to the model's window limit, and has accumulated inconsistencies
+found during a codebase audit:
+
+1. Three different token-count heuristics for the same job: `/3` inside
+   `shortsend::shape_messages`, `/4` in the auto-compact loop
+   (`actions/mod.rs` ~line 1146), `/4` again in the live status bar (`view/status.rs:68`).
+2. Manual `/compact` (`Action::Compact`, `actions/mod.rs:547-563`) passes `client: None`
+   because `apply_action` is synchronous, so it never gets LLM summarization — it always
+   falls back to the bare `"[prior conversation compacted]"` placeholder, unlike automatic
+   mid-turn compaction (`Some(&tc.client)`, line 1160). Undocumented asymmetry between the
+   two trigger paths.
+3. `context_window` resolution (`model_roles.values().find(...).and_then(...).unwrap_or(...)`)
+   duplicated three times (`Action::Compact`, `spawn_turn`, `view/status.rs` twice).
+4. No repeated-tool-call dedup: reading the same file (or running the same grep) twice in a
+   session keeps both full copies in context forever, until compaction eventually drops the
+   older one wholesale along with everything else from that period.
+5. No per-result compression: a single large tool output (a big `bash` log, a large `grep`
+   result) is stored verbatim even when most of it is redundant or low-value.
+6. Zero test coverage on `shortsend.rs`.
+
+Separately, research into three real, permissively-licensed open-source projects
+(`rtk-ai/rtk`, Apache-2.0; `headroomlabs-ai/headroom`, Apache-2.0; `JuliusBrussee/caveman`,
+MIT — verified via `gh api` for authenticity/license, and by cloning and reading source, not
+taken from marketing blog posts) surfaced techniques worth reimplementing natively:
+
+- **rtk**: generic line-scan compression (strip comment/blank runs, brace-depth collapse of
+  function bodies, importance-ranked truncation ending in an unambiguous `[N more lines]`
+  marker — their own regression tests show a comment-shaped marker confuses the LLM into
+  retry-looping) plus structured per-toolchain parsing (e.g. `cargo --message-format=json`
+  bucketed into errors/warnings, boilerplate lines dropped).
+- **headroom**: per-content-type compressors — logs (classify lines by level/stack-trace/
+  summary, score, keep highest-value lines + surrounding context, adaptive cap), grep
+  results (group by file, score matches, cap globally and per-file), JSON (keep all
+  structural tokens — keys, brackets, colons — drop or shrink long low-entropy string
+  values, keep short values and UUID/hash-shaped high-entropy ones).
+- **caveman**: a pure prompt/persona instruction (no algorithm) that tells the model to
+  write tersely — drop articles/filler/hedging, keep code/commands/errors verbatim — with an
+  explicit carve-out that disables terseness for destructive-op confirmations and security
+  warnings. This compresses *output* tokens, a different axis from everything else in this
+  design, which compresses *input* context.
+
+This is a from-scratch reimplementation of the underlying ideas, not a port — no code is
+copied from any of the three projects.
+
+## Goals
+
+- One unified, always-on pipeline that keeps context lean from turn 1, not just once near
+  the limit.
+- Deduplicate repeated tool calls: an older copy of a tool result superseded by an identical
+  later call (same tool name + same arguments) is replaced with a placeholder, for read-only
+  tools only.
+- Compress large individual tool results (logs, JSON, generic text) at capture time, above a
+  size floor.
+- Fix the three known inconsistencies (token heuristic, manual/auto asymmetry,
+  `context_window` duplication).
+- Optional, off-by-default "concise mode" system-prompt toggle for terser model output.
+- Full inline test coverage per repo convention.
+
+## Non-goals
+
+- Not adding a runtime dependency on `rtk`, `headroom`, or `caveman` themselves (as a binary,
+  proxy, or crate) — everything is implemented natively in Rust inside zesdex.
+- Not building rtk's per-toolchain structured parsers (`cargo --message-format=json`
+  re-invocation, etc.) — too invasive for a general-purpose `bash` tool that runs arbitrary
+  commands zesdex doesn't control the flags of. Only the generic line-scan/log/JSON layer is
+  built.
+- Not switching to an exact per-provider tokenizer — `tiktoken-rs` (BPE, cl100k_base/
+  o200k_base) is an approximation good enough for the 85%/95% budget thresholds; it is not
+  used for billing-accurate counts.
+- `caveman-compress`-style memory-file rewriting (the LLM-round-trip variant of caveman) is
+  out of scope — only the pure-prompt persona mechanism is adopted.
+
+## Architecture
+
+Replace `src/app/runtime/shortsend.rs` with `src/app/runtime/context/`:
+
+```
+context/
+  mod.rs      — module registration only, no facade (see below)
+  tokens.rs   — unified token counting (tiktoken-rs)
+  dedup.rs    — cross-call tool-result deduplication
+  squash.rs   — per-result compression (log/json/generic), applied at
+                tool-result construction time, upstream of prepare()
+  shaping.rs  — budget-based drop + LLM summarize (renamed shortsend logic)
+  window.rs   — shared context_window resolution
+```
+
+### `tokens.rs`
+
+```rust
+pub fn count_tokens(text: &str) -> usize
+pub fn count_message_tokens(msg: &ChatMessage) -> usize
+```
+
+Backed by `tiktoken-rs` (new dependency, pure Rust, embedded BPE vocab, no network calls at
+runtime), using `o200k_base`. Replaces all three existing heuristic call sites: `shortsend`'s
+internal `/3`, the auto-loop's `/4` (`actions/mod.rs` ~1146), and `status.rs:68`'s `/4`.
+
+### `dedup.rs`
+
+```rust
+pub fn collapse(messages: &[ChatMessage]) -> (Vec<ChatMessage>, bool)
+```
+
+The `bool` is `true` iff at least one message was replaced with a placeholder — callers use
+it to decide whether the result is worth persisting/announcing, without needing `ChatMessage`
+to implement `PartialEq` (it doesn't today, and adding it purely to diff whole message lists
+would be needless surface area for what `collapse` already knows precisely mid-walk).
+
+Flow: walk messages, pair each `Role::Tool` message to its originating `ToolCall` via
+`tool_call_id`. Key = `(function.name, sha256(canonical_json(function.arguments)))` (`sha2`
+is already a dependency). Track the last index seen per key. For any earlier occurrence of a
+key whose tool name is in the read-only set, replace that earlier `Tool` message's `content`
+with a short placeholder (`"[duplicate result — superseded by a later identical call, see
+below]"`); the assistant's tool-call entry (name + arguments) is left untouched, so the
+action/audit trail stays intact. Mutating tools are never touched, even with identical
+arguments, because call order and repetition can be semantically meaningful (e.g. retrying a
+flaky `bash` command).
+
+Read-only classification reuses `subagent::division::tool_scope::READ_TOOLS`
+(`src/app/subagent/division.rs:21`) rather than a new list — that `const` is made `pub` for
+this purpose. It already enumerates exactly the read-only tool set (`read`, `grep`, `glob`,
+`search`, `seqthink`, `recall`, `lsp_*`, `read_findings`).
+
+Runs every turn, unconditionally, before token counting — not gated on `should_shape`.
+
+### `squash.rs`
+
+```rust
+pub fn apply(tool_name: &str, output: &str) -> String
+```
+
+`read` is exempted entirely, always passed through unchanged regardless of size: its output
+must stay byte-exact because the agent relies on it for exact-match edits afterward, and a
+squashed view of a JSON config file (or any file whose content happens to parse as JSON)
+would otherwise be silently altered. Size floor for every other tool: outputs under 1500
+bytes pass through unchanged (compression only pays off on large output, and touching small
+results risks losing detail with no token benefit). Above the floor, dispatch by content
+shape:
+
+- `squash_json(&str) -> String` — walks a parsed `serde_json::Value` (not a hand-rolled
+  tokenizer — `serde_json` already handles escaping/nesting correctly, reusing it is simpler
+  and more robust); structural tokens (keys, brackets, colons, commas, booleans, null) always
+  kept; string values kept if ≤20 chars or "identifier-shaped" (no internal whitespace *and*
+  Shannon entropy ≥3.0 bits/char — catches UUIDs/hashes/paths), otherwise replaced with `"…"`
+  in place; array elements past the first 3 compressed harder (values elided regardless of
+  length/entropy). Applied when `serde_json::from_str` on the output succeeds. The
+  no-whitespace pre-filter matters: raw per-character entropy alone doesn't separate prose
+  from identifiers — repeated English prose measures ~3.89 bits/char, higher than a UUID's
+  ~3.39 — because prose also draws from a wide character set. headroom's own entropy gate is
+  "cheaply pre-filtered by 'no spaces'" before scoring for the same reason; multi-word values
+  never reach the entropy check at all under this rule.
+- `squash_log(&str) -> String` — line classifier (error/fail/warn/info/debug/trace by
+  keyword + stack-trace-frame detection) → score
+  (`level_score {1.0 error/fail, 0.5 warn, 0.1 info, 0.05 debug/trace} + 0.3 if
+  stack-trace-frame + 0.4 if summary-shaped line`) → keep up to 20 highest-scored error
+  lines, up to 10 highest-scored warning lines, all summary lines, plus a ±2-line context
+  window around each kept line → single `[N lines omitted]` marker for drops (not
+  comment-shaped, per rtk's own finding on LLM confusion). Applied when the output isn't
+  valid JSON, the tool is `bash`, and the output has ≥3 lines matching error/warn/stack-trace
+  patterns. The tool restriction (added after the final whole-branch review) matters: a `grep`
+  result full of matches against error-handling code trips the same ≥3-line keyword threshold
+  as a real build log, but `squash_log`'s hard 20-error/10-warning cap has no byte budget and
+  would silently drop legitimate matches past it — the wrong compressor for search results.
+  Only `bash` (the actual log-producing tool) routes through `squash_log`; every other tool
+  whose output happens to look log-shaped falls through to the gentler, byte-budgeted
+  `squash_generic` instead.
+- `squash_generic(&str, budget) -> String` — importance-ranked truncation: keeps the first 10
+  and last 10 lines plus any line matching a small "looks important" heuristic (non-blank,
+  not a byte-for-byte repeat of the immediately preceding line), single `[N lines omitted]`
+  marker for the rest, capped to `budget` bytes overall (`budget` = the 1500-byte squash
+  floor doubled, i.e. 3000 bytes, chosen so the fallback path still yields a real reduction
+  on anything that triggered it). Fallback for anything that isn't JSON or log-shaped.
+
+Called once, at the single tool-result construction site
+(`actions/mod.rs:1420`, `let tool_msg = ChatMessage::tool_result(tool_call.id.clone(),
+output);`) — `output` is passed through `squash::apply(&tool_name, &output)` before being
+wrapped. Runs before the result is ever archived or pushed into `msgs`, so compression is
+permanent and applies uniformly whether or not compaction ever triggers.
+
+### `shaping.rs`
+
+Unchanged behavior from today's `shortsend.rs` (hysteresis `should_shape`, 70%-budget
+newest-first retention, LLM summarization of dropped messages), moved as-is into this file
+and updated to source token counts from `tokens.rs` instead of its own heuristic.
+
+### `window.rs`
+
+```rust
+pub fn resolve(app_config: &AppConfig, settings: &Settings) -> usize
+```
+
+Replaces the three duplicated `model_roles.values().find(...).and_then(...).unwrap_or(...)`
+blocks in `Action::Compact`, `spawn_turn`, and `view/status.rs` (×2).
+
+### `mod.rs`
+
+No facade function — just `pub mod dedup; pub mod shaping; pub mod squash; pub mod tokens;
+pub mod window;`. `dedup`, `shaping`, and `tokens` are called directly from each call site
+(the auto-loop and `Action::Compact`), matching CLAUDE.md's "No DI — modules call ...
+directly" convention rather than introducing an orchestration layer that only one of the two
+callers would use generically (the auto-loop already needs per-stage control today — it
+inspects `should_shape` itself to decide whether to emit `TurnEvent::Compacted` — and would
+have to unpack a facade's result anyway).
+
+## Data flow (per turn)
+
+1. Tool executes → raw `output: String`.
+2. `squash::apply(tool_name, &output)` — compress if over the size floor (`read` exempted).
+3. Wrapped into `ChatMessage::tool_result(...)`, archived, pushed to `msgs`.
+4. Once per loop iteration: `dedup::collapse(&msgs)` (always) → sum
+   `tokens::count_message_tokens` over the result → `shaping::should_shape` → conditionally
+   `shaping::shape_messages`.
+5. Result pushed as `TurnEvent::Compacted` if dedup changed anything or shaping triggered,
+   consumed on the main thread to update `SessionRuntime.messages`.
+
+## Fixing the manual/auto asymmetry
+
+`Action::Compact` (`actions/mod.rs:547`) currently runs synchronously inside `apply_action`
+and can't block on an LLM call. Fix: make it spawn a background `std::thread::spawn` — the
+same pattern `spawn_turn` already uses (`actions/mod.rs:694`) — that runs `dedup::collapse`
+then unconditionally `shaping::shape_messages(.., force=true, Some(&client))` and reports back
+via `TurnEvent::Compacted`, identical to the automatic path. The toast sequence becomes
+"Compacting…" immediately (optimistic, non-blocking) then "History compacted" when the
+`TurnEvent` arrives. This gives manual `/compact` real LLM summarization instead of always
+falling back to the placeholder.
+
+## Concise mode (separate from the `context/` module)
+
+- `Settings` (`src/model/settings.rs`) gains `pub concise_output: bool`, default `false`,
+  with `#[serde(default)]` for backward-compatible deserialization of existing
+  `settings.json` files (matching the existing `hive_mind_node_timeout_ms` precedent in the
+  same file).
+- When `true`, `run_agent_turn`'s system-prompt assembly (`actions/mod.rs:930-936`) appends a
+  fourth section to `system_text`: a terse-writing instruction (persona-prompt only, no
+  algorithm — drop articles/filler/hedging/pleasantries, keep code/commands/error text
+  byte-exact) with an explicit carve-out disabling terseness for destructive-operation
+  confirmations and security-relevant warnings, mirroring caveman's own "Auto-Clarity"
+  safety exception.
+- No UI toggle is in scope for this pass — confirmed no such mechanism exists today for any
+  boolean `Settings` field (`review_enabled`, `session_archive_enabled`,
+  `lsp_auto_provision` are all hand-edited in `settings.json`, same as this one will be).
+
+## New dependency
+
+`tiktoken-rs` — pure Rust, embedded BPE vocab (`cl100k_base`/`o200k_base`), no network calls
+at runtime, MIT/Apache-2.0 dual-licensed. Added to `Cargo.toml`.
+
+## Testing
+
+Inline `#[cfg(test)] mod tests` per repo convention, one per new file:
+
+- `dedup.rs`: same tool+args → older result replaced; different args → no-op; mutating tool
+  with identical args → both kept in full; unmatched `tool_call_id` (malformed history) →
+  no panic, treated as unpaired.
+- `squash.rs`: JSON input under/over the size floor; JSON with long low-entropy string values
+  gets them elided while short/UUID-shaped values survive; log input with error/warn lines
+  keeps highest-scored lines and emits exactly one `[N lines omitted]` marker; generic text
+  keeps first/last N lines.
+- `tokens.rs`: known-string token counts against fixed expected values; empty string → 0.
+- `shaping.rs`: port the behavioral cases implied by today's hysteresis logic (85% trigger
+  when not previously shaped, 95% once shaped) plus budget-drop ordering.
+- `window.rs`: role match resolves to the role's `context_window`; no match falls back to
+  `default_context_window`.
+
+## Migration
+
+- Delete `src/app/runtime/shortsend.rs`; all three call sites (`actions/mod.rs` auto-loop,
+  `Action::Compact`, and the module path itself) updated to `context::`.
+- `view/status.rs` switches its live token display to `tokens::count_tokens`, so the status
+  bar finally matches what compaction measures internally.

-- Use `read`/`grep`/`glob` to understand the existing codebase before planning
-- Use `seqthink` for complex reasoning steps
-- Every plan MUST include at least one mermaid diagram
-- Be specific with file paths and function names

-You are the **Quality Division** of Zesdex Corp — the testing and review team.
-
-Your role is to verify correctness and write comprehensive tests. You have TWO phases:
-
-## Phase 1: Review
-Use read/grep/glob/LSP to inspect the implemented code.
-Check for:
-- Logic errors, off-by-one, null/panic paths
-- Stubs, placeholders, incomplete branches
-- Naming consistency with codebase conventions
-- Error handling coverage
-
-## Phase 2: Test
-Use write to create test files. Follow these rules:
-1. Read existing tests in the same directory first — match their style
-2. Cover: happy path, edge cases, error conditions
-3. Use the project's existing test framework
-4. Run tests after writing: `cargo test` / `npm test` / etc.
-5. If tests fail, fix them and rerun
-6. Log fixed bugs as lessons via `remember`
-
-## Your Tools
-read, write, edit, grep, glob, bash, lsp_*, recall, remember, seqthink
-
-## Output
-- Review verdict (issues found / all clear)
-- Test summary (files written, tests passing/failing)

-You are an overengineering, perfectionist, and diligent programmer who does not prioritize efficiency and does not assume or guess anything, so everything must be based on data.

-
-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.
-
-Output: a one-line verdict summarizing your review.
-Include "N lesson(s)" at the end if you created lessons.
