"""``run-team.py`` — R720 agent-team operator entry CLI (design §3.3.1, §7.1 P1).

This is the **entry CLI** named in the design (§2 "entry CLI ``run-team.py``";
§9 "operator CLI"). It is the small manual path over the durable
``pending_questions`` ledger that §3.3.1 ("Manual path") requires::

    A small CLI over the ledger lets an operator list ``open``/``parked``
    questions, re-deliver, force-expire, or answer on a task's behalf; a stuck
    task parks rather than spins. Destructive CLI actions (force-expire,
    answer-on-behalf, force-resume) are audit-logged and require an explicit
    confirmation flag.

It imports the committed FOUNDATION contracts verbatim — it does not redefine
them:

* :mod:`agent_team.db.schema` — :func:`connect`, :func:`init_db`,
  :func:`answer_question`, :func:`expire_question`, :func:`supersede_question`,
  :data:`QUESTION_STATES`.
* :mod:`agent_team.state_store` — :func:`atomic_write` for the append-only,
  crash-safe audit log of destructive actions (§6.7 discipline).

Per the build constraints this is **pre-deployment scaffolding**: it provisions
nothing, enables no live CI, and performs no network or rsync. It only reads and
mutates the local SQLite ledger and writes a local audit log.

Subcommands (P1 surface):

* ``init-db`` — create/upgrade the agent-team tables in the ledger DB
  (idempotent; wraps :func:`init_db`).
* ``list`` — list ``open`` (default) or any-status pending questions; with
  ``--parked`` it lists questions whose status is read as parked context. Pure
  read; no confirmation needed.
* ``show`` — print one question row by ``question_id``. Pure read.
* ``expire`` — force-expire an ``open`` question (DESTRUCTIVE: requires
  ``--confirm``; audit-logged). Maps to :func:`expire_question`.
* ``answer`` — answer a question on a task's behalf (DESTRUCTIVE: requires
  ``--confirm``; audit-logged). Maps to :func:`answer_question`.
* ``supersede`` — mark a stale question ``superseded`` (DESTRUCTIVE: requires
  ``--confirm``; audit-logged). Maps to :func:`supersede_question`.
* ``intake-github`` — poll a repo for labeled open issues and start one pipeline
  task per not-yet-ingested issue (one pass). Reads issues + calls the committed
  coordinator intake entry only; no CI, OIDC, or git/patch apply. Opt-in/inert.
* ``intake-checker`` — the Plane-1 -> Plane-2 cross-plane loop (P5): read one or
  more checker report JSON files / a dir, select CONFIRMED findings at/above a
  severity threshold (default ``high``), de-dup, and start one remediation task
  per unique finding via the committed coordinator intake entry. Reads local
  report JSON only; no CI, OIDC, network, or git/patch apply. Opt-in/inert.
* ``fix`` — plan a Plane-1 Tier-3 dep-bump fix for one confirmed dependency-cve
  finding (spec via Claude + minimal bump patch via DeepSeek) and, in
  ``--dry-run``, print the spec + patch + the org-CI ``workflow_dispatch`` inputs
  WITHOUT dispatching. Opt-in/inert: it binds no dispatcher and holds no write
  token; live dispatch is provisioning-gated (the P3-live apply/verify surface).

Exit codes: ``0`` success, ``1`` operational failure (e.g. row not found, the
compare-and-set lost the race), ``2`` usage error (argparse).
