"""The manager AI: orders become tasks, tasks become team work.

This is the layer that turns a user's sentence into the engine's machinery, and
it is deliberately the *only* place that interprets the manager's tags:

* **3.1 chat** — the user talks to the manager; the manager replies and may
  emit ``CREATE_TASK`` (≤ 3), ``PAUSE_TASK`` / ``RESUME_TASK`` / ``CANCEL_TASK``
  and ``HIRE`` / ``UPDATE_EMPLOYEE`` / ``FIRE``. Tasks get a pipeline state at
  ``pending_manager_review`` and are linked to the thread. The prompt asks for
  **atomic tasks that do not touch the same files**, and the chat's model calls
  are billed like every other call.
* **3.2 team** — hiring picks a *granted* model for the requested neutral tier,
  respects the employee cap and the "last manager" rule, and publishes
  ``team.changed``. Users choosing from the UI give a role and a tier only;
  model identity never crosses the API.
* **3.3 triage** — ``ASSIGN`` (pipeline + assignee), ``REJECT`` or ``ASK_USER``.
  Assignee selection defaults to the **least busy** active employee with the
  role, and a name is matched fuzzily **inside the org only**.
* **3.4 final / error** — ``COMPLETE`` → ``merge_request``, ``REVISE`` → back to
  the developer with ``cycle + 1``; ``RESOLVE_ERROR`` retries with a hint,
  ``CANCEL`` ends the task.
* **3.5 knowledge** — ``KNOWLEDGE`` tags are recorded through ``MemoryPort``.
* **3.6 bootstrap** — a new org gets manager + planner + developer + tester on
  the strongest / balanced / fast granted tiers; with nothing granted the
  employees are created inactive and a system message says so. Idempotent.

Every query here is tenant-scoped: the manager of org A can never assign an
employee of org B, even by exact name.
