"""Tests for the Chronos cron-fire webhook ON THE DASHBOARD APP (web_server).

Regression guard for the relocation bug: the fire webhook MUST live on the
dashboard FastAPI app (`hermes_cli.web_server.app`) — the agent's public HTTP
surface on hosted deployments — not only on the aiohttp APIServerAdapter (which
hosted agents don't expose). It must:
  - be a registered route on the dashboard app,
  - be in PUBLIC_API_PATHS so the dashboard cookie gate doesn't 401 it before
    the JWT verifier runs,
  - reject a bad/missing NAS-JWT with 401 (the JWT is the real gate),
  - 400 on missing job_id,
  - on a valid token, resolve the job's profile and run fire_due in the
    background, returning 202.
