"""temper_rejects — the Ausschuss-Station page-module for the SPRO gateway.

A central, **login-free** reject-booking terminal for ALL presses' tempered
carts (Werk Cadolzburg). Mounted into the SPRO Universal Gateway as a git
submodule at ``<gateway>/modules/temper_rejects/`` and discovered by the kernel
module loader (``app.core.modules.load_modules``), which imports this package and
calls ``register(app)``.

It does two things:

* mounts the built Vue SPA (``dist/``) as static files under ``/module/temper_rejects``;
* exposes a small no-auth JSON API under ``/module/temper_rejects/api`` — reads
  (tempered carts per ``ttId`` + reject reasons) AND one narrow write
  (``POST /reject`` → one row in ``production.rejects``).

No login / device context by design — this is a central shop-floor terminal. The
existing device-scoped ``POST /press/rejects/send`` derives the press from the
device JWT, which is useless for a multi-press terminal; hence the un-scoped
variant here, which takes ``press`` + ``ttId`` from the request body. Non-sensitive
shop-floor data. Security posture (network/reverse-proxy vs. a static token) is an
open question — see this repo's README + ``.claude/memory/ausschuss-station.md``.

See ``agent_docs/vue-page-modules.md`` in the gateway repo for the module runbook.
