Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Give the harness one general way to wake a settled bot, then put two +things on it: routines that fire from app events instead of only a clock, and +background executors that let a bot work on something while staying free to +talk. + +**Architecture:** All three items are one seam — the connector-resume path at +`server/index.ts:2139–2196`, which is already a wake queue hardcoded to a +single trigger. Item 1 lifts it into `server/wakes.ts` with the dispatch policy +intact and the runtime injected (index.ts keeps `startTurn`, +`runGroupMemberTurn` and `groupQueues`). Items 2 and 3 then become wake +producers rather than new turn-dispatch paths. + +**Tech Stack:** TypeScript (`--experimental-strip-types`), vitest, pnpm. +Tests: `pnpm vitest run `; typecheck: `pnpm typecheck`. + +**Spec:** `docs/plans/grok-parity-upgrades.md` — Round 2.

Behavioural equivalence is the acceptance bar** — the existing connector-resume tests must pass untouched, and `dispatchConnectorResume` must end up a thin wake producer rather than a second implementation. +- A listener event is third-party text.
