teamlisted

Coordinated multi-lane execution through native subagent fan-out (no tmux). Use when a task splits into 3+ independent parallel lanes, each owning its own verification. Maintains an evidence-backed task board via the sanctioned state writer; the leader may not declare success until every task has completion evidence.

# team — native subagent fan-out You (the main thread) are the leader. Workers are `executor` subagents you spawn and await directly — there is no tmux, no worker panes, no claim leases, no heartbeats. What survives is the philosophy: explicit lanes, a durable task board, per-task completion evidence, and a shutdown phase computed from evidence, never from optimism. ## State plumbing - Resolve the session id, state root (`.cat/_session-{sid}`), and helper script path from the `<cat-harness-router>` context block; fall back to `${CLAUDE_PLUGIN_ROOT}/scripts/cat-state.mjs`. Below, `$CAT` means that script path and every invocation takes `--session <sid>`. - Ensure the session tree exists: `node "$CAT" init --session <sid>`. - Phases: `starting → running → complete`; terminal alternates `awaiting_integration`, `failed`, `cancelled`. Initial phase is `starting`. While `starting`, the PreToolUse guard blocks mutations — do not move to `running` until the gates below pass. - ALL team state writes go through the sanctioned writer — never the Write tool (`state/**` is runtime-owned; the guard denies direct writes always): node "$CAT" state write --session <sid> --skill team --json - passing the full envelope on stdin. The task board is the `board` object embedded in that envelope; the sanctioned writer owns the board's canonical on-disk home at `.cat/_session-{sid}/state/team-board.json`. Read state back with `node "$CAT" state read --session <sid> --sk
