# Documentation Map

Authoritative inventory of this repository's documentation surface: every doc that must be kept in sync, what each contains, and the stable anchors to grep for when placing an edit. Section line numbers drift — grep the anchor strings, don't trust line numbers.

## Tier 1 — primary, always consider

### `README.md` (English, canonical)
The source of truth most other docs mirror. Key sections:
- **Feature table** — rows like `**Kanban Board**`, `**Transcript Cache**`, `**Pre-Existing Session Detection**`, `**Continuous Project Sync**`. Grep a neighboring row label.
- **Data-flow numbered list** — bullets describing hook ingestion, the watchdog, periodic sweep, continuous sync. Grep `Error detection watchdog` / `periodic server sweep`.
- **Agent State Machine** + **Session State Machine** — two `mermaid stateDiagram-v2` blocks. Grep `stateDiagram-v2`.
- **Hook Events table** — `| Hook Type | Trigger | Dashboard Action |`. Lists `SessionStart`…`SessionEnd`, plus synthetic `Compaction`, `APIError`, `TurnDuration`, `ToolError`, `Interrupted`. Grep `## Hook Events`.
- **Configuration / Environment Variables table** — `| Environment Variable | Default | Description |`. Grep `DASHBOARD_PORT` or `DASHBOARD_HOST`.

### Translations

This build ships English only. `README-VN.md`, `README-CN.md` and `README-KO.md` were removed, as were the `zh` and `ko` UI locales — do not recreate them.
Standalone full translations of `README.md`. **Every** README change must be mirrored here at the corresponding section. Conventions:
- Keep in English/code: identifiers, env-var names, event-type names, `awaiting_input_since`, `pendingInterrupt`, "watchdog", `fs.watch`, model IDs, mermaid transition labels.
- Translate prose. "Waiting" → **Đang chờ** (vi) / **等待中** (zh) / **대기 중** (ko). "watchdog" often kept; in zh sometimes 看门狗.

### `ARCHITECTURE.md`
- **Module responsibility table** — one row per source file (`scripts/import-history.js`, `lib/transcript-cache.js`, `routes/hooks.js`, `server/index.js`, …). Update the row whose file you changed. Grep the file path.
- **Data-flow + sequence diagrams**, **state machines**, **Continuous background sync** prose block (grep `Continuous background sync`).
- **Event types line** — grep `| Event types |`.
- **ERD / schema** mermaid + `event_type "PreToolUse|PostToolUse|Stop|etc"`.

### `server/README.md`
Backend reference: routes table, **Error Detection Watchdog** / **User-Interrupt (Esc) Recovery** / **Continuous Project Sync** sections, Agent/Session lifecycle mermaid diagrams, Environment Variables bash block under `## Deployment`. Update for any backend behavior, route, state, env var, or background service.

### `client/README.md`
Frontend reference: component list, **Event Types** table (WebSocket broadcast message types like `session_created`, `agent_updated`), session/agent status TypeScript unions. Update for new WS message types or client-facing behavior. NOT needed for server-only changes the UI already renders generically.

### `docs/HOOKS.md`
Per-hook deep reference (`### 1. SessionStart` … `### 8. SessionEnd`), the `awaiting_input_since` overlay rules, the "User interrupts (Esc) — no hook fires" section, transcript-derived sync. Update for any hook semantics or state behavior.

### `docs/DATABASE.md`
Schema reference: `sessions` / `agents` / `events` tables, column docs, status CHECK constraints, lifecycle mermaid diagrams. Update for schema or state-machine changes.

### `docs/API.md`
REST API reference (endpoints, params, example responses). Update for route/response changes. Pair with `server/openapi*.js` (code, not docs).

### `docs/PLUGINS.md`
Plugin/marketplace docs incl. an **Event Types** enumeration line — keep it in sync with the canonical event-type list.

### `docs/MCP.md` + `mcp/README.md`
MCP server + tool reference. Update for new/changed MCP tools.

### `docs/I18N.md`
i18n architecture: **Supported languages** list, `supportedLngs`, the 15 namespaces. Update when adding a language or namespace. Client UI strings live in `client/src/i18n/locales/{en,zh,vi}/*.json` (code).

## Tier 3 — situational

- `.env.example` — every env var belongs here with a sane default + comment.
- `INSTALL.md`, `SETUP.md` — install/run commands.
- `CLAUDE.md`, `AGENTS.md` — agent working guides; update when commands, file locations, or workflows change.
- `docs/README.md` — docs index; add a link when a new `docs/*.md` is created.
- `vscode-extension/README.md`, `statusline/README.md` — surface-specific; update only when that surface changes.

## Consistency invariants

- The **event-type set** must match across: `README` hook table, `ARCHITECTURE` Event types line, `docs/PLUGINS.md`. When adding one, grep the existing set (e.g. `TurnDuration`) across all and add everywhere it appears.
- **Env-var set** must match across: README tables, `server/README.md`, `.env.example`, and any inline `ARCHITECTURE` mention.
- **State-machine diagrams** are duplicated across README, `server/README.md` and `docs/DATABASE.md`. A transition change touches all of them.
- Run `scripts/doc-coverage.sh <term>` to confirm a new identifier/var/event reached every doc that should mention it.
