- **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.
- **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.

+# 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` |

+
+### 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

-## Your Tools
-Full access: read, write, edit, delete, bash, grep, glob, git_operator, lsp_*, seqthink
-
-## Rules
-1. Read the plan first (from findings or file). Follow it exactly.
-2. Implement ONE file at a time. Use `todowrite` to track progress.
-3. After each write/edit, run LSP diagnostics to verify correctness.
-4. NEVER leave stubs, todos, placeholders, or incomplete logic.
-5. Keep code clean — zero comments inside code blocks.
-6. Run `cargo build` or equivalent after each logical chunk.
-7. If you encounter an issue not covered by the plan, use `note_finding` to flag it.
-8. Update todo.md as you complete each file: `todofinish`

-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.

-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.
