"""No-auth JSON API for the Ausschuss-Station (central reject-booking terminal).

Served same-origin under ``/module/temper_rejects``. Three routes:
  * GET  /module/temper_rejects/api/overview?window=7T  → tempered carts (per ttId)
  * GET  /module/temper_rejects/api/reasons             → active reject reasons
  * POST /module/temper_rejects/api/reject              → book one Ausschuss

No ``verify_token`` dependency: this is a central login-free terminal (no device
context). ``press`` + ``ttId`` come from the request BODY, unlike the device-scoped
``POST /press/rejects/send`` in fastpress.

── STATUS: BASE SCAFFOLD ────────────────────────────────────────────────────────
Returns realistic SAMPLE data shaped EXACTLY like the frontend contract
(``src/types/station.ts``); POST /reject validates + echoes success WITHOUT writing.
This lets the terminal render + exercise the booking flow with no database.

TODO — wire real data (see ``.claude/memory/ausschuss-station.md`` in the gateway):
  * ``from .._db import run_select_query, transaction``
  * OVERVIEW: read ``production.temper_tracking`` across ALL presses (un-scoped),
    one row per ``ttId``, newest first by ``ttOutOfOvenAt`` (status='done'); join
    ``active_orders``/``finished_orders`` for article. Per entry, add the ORDER's
    5-station distribution (reuse fastpress ``temper._temper_aggregates_all``:
    notYetSent / sentToTemper / onWayToOven / inOven / finishedTempering).
  * REASONS: ``SELECT id, reason_de, reason_en FROM settings.reject_reasons WHERE active=1``.
  * REJECT: one INSERT into ``production.rejects`` inside a ``transaction()`` (same
    shape as fastpress ``rejects.send_reject``). Booking references the cart →
    needs the additive nullable ``rejTtId`` column (DBA applies it; runtime account
    has no ALTER). Confirm the security posture (network-only vs. a static token)
    before exposing the write.
