## Project mission
- Maintain a reliable local-first dashboard for Claude Code session monitoring.

- **A workspace's sessions are the ones it OWNS, never the ones that ran in its folder.** `sessions.lane_id` is stamped by `bindRunSession` (`server/routes/hooks.js`) for the session a dashboard pane holds — first writer wins, a nested `claude -p` excluded — and no route sets it. A Codex/Antigravity session (their hooks are opt-in, so a pane may never learn its session) is also stamped by `claimToolSessions` (`server/lib/dashboard-runs.js`, called by both pollers and once at start): the lane of the newest same-tool dashboard run in the session's folder that was live when the session started, never a Claude session. A new Claude pane is started with `--session-id <uuid>` (`spawnRun`), so its `dashboard_runs.session_id` is known before any hook and a hook that carries no `run_id` (a hook handler older than `AGENTHUB_RUN_ID` forwarding) is still stamped from that run (`laneForSession`). Every workspace session list reads `GET /api/sessions?lane=<id>` — which also counts a still-unstamped session one of the lane's `dashboard_runs` holds, because hooks reach only the lowest-port dashboard on a shared DB and that one may be an older build that never stamps — and shows nothing else (no "other sessions in this folder"). Do not go back to listing a workspace by `cwd`, and do not guess ownership for old history.
- **A session's worktree is `claude --worktree`'s, resolved from the session row — and removing it never forces.** A Worktree start passes `--worktree=<server-made name>` (the `=` form: `-w [name]` eats the prompt otherwise) and Claude Code makes, populates and cleans up `<repo>/.claude/worktrees/<name>`; AgentHub only excludes `/.claude/worktrees/` at the repo root. A git route, a resume or a removal may work in a session's worktree only through `sessionWorktree` (`server/lib/session-worktree.js`: the session owned by the lane, its cwd not the lane's folder, registered by `git worktree list`) — `?session=` on the git routes answers `ENOWORKTREE` rather than falling back to the main folder. `POST /api/lanes/:id/session-worktree/remove` (same-origin, `confirm: true`, refused while a live pane holds the session) is the ONE dashboard path that deletes a worktree: `git worktree remove` with no `--force`, `git branch -d` never `-D`, a live-pid lock refused. Do not add a force, and do not let it touch a lane's own folder.
- **Opening a session never resumes it — only SENDING a message to it does.** The sidebar and a workspace home ATTACH pane 0 to a session's live tmux pane (`/workspace?lane=<id>&run=<runId>`, `attachRequest` on `LaneConsolePane`) or, for an ended one, open it in its workspace like Claude Desktop (`/workspace?lane=<id>&session=<id>`, `client/src/components/lanes/SessionReplay.tsx`: its conversation read-only plus a prompt box; the console is only hidden, CSS). A resume re-reads the whole transcript into context, so it happens only on an explicit action: a message SENT from that replay (`resumeSessionId` + `prompt`, first free slot), the transcript page's **Resume**/**Fork** (`SessionResumeButton.tsx`, behind a warning), or the ticked sessions of the **Resume interrupted sessions?** dialog (`InterruptedSessionsPrompt.tsx`, `GET /api/run/interrupted` — runs whose pane died under them; opening it resumes nothing). The analysis page `/sessions/<id>` is reached from the session view's **Analyst** button (beside Files/Changes in the right panel). Do not add a path that resumes on a click. A resume is refused while a live pane holds the session (`409 ESESSIONLIVE` with that pane's `run_id`) — open that pane instead; a fork makes a new session and is allowed.
- **A chat artifact runs in its own sandbox, never on the dashboard's origin.** The artifact panel (`client/src/components/run/ChatFilePreview.tsx`, `client/src/lib/artifactView.ts`) runs model-written HTML/Mermaid/React in an `<iframe srcdoc sandbox="allow-scripts …">` and an SVG in `sandbox=""` — never add `allow-same-origin` (the script would read the dashboard's cookies and call its API as the user), never render one with `dangerouslySetInnerHTML`, and keep its CDN libraries pinned to exact versions. An HTML FILE opened from the Changes panel, a Chat file preview or the File Explorer runs in the same sandbox (`client/src/components/HtmlFrame.tsx`); its relative CSS/scripts/images are fetched by the DASHBOARD through the existing download routes and inlined (`client/src/lib/htmlInline.ts`) — never add a route that serves a folder to the frame without the login cookie. Versions are rebuilt from Write/Edit inputs (kept up to 256 KB by `server/lib/transcript-message.js`); no copy is stored, and Save to Artifacts uses the Hub's own `pinFile`/upload routes.

- **A `cwd` can back at most one lane per tool, not one lane overall.** Uniqueness is the composite `idx_lanes_cwd_tool` (`cwd`, `tool`), not `cwd` alone — Repo/Adopt mode (`POST /api/lanes/ensure`) lets the same directory carry a `claude` lane and a `codex` lane side by side, shown as two separate cards. `resolveLaneByCwd(cwd, tool)` takes an optional `tool` filter for exactly this; hook ingestion (`touchLaneFromHook`) pins it to the hook's own tool — `claude`, `codex` for a hook posted with `tool: "codex"`, or `antigravity` for one posted with `tool: "antigravity"` (the Codex and Antigravity hook rules above) — so a hook event never touches the other tool's lane sharing the path, and stage detection (`resolveLaneForWork` + `detect`) runs for `claude` only. Worktree mode is unaffected — it already allocates a unique directory per lane.
See `docs/LANES.md` for full guide: stage reporting, custom templates, lane actions, and the five node states.
