"""Per-job reasoning_effort override: store contract + scheduler precedence.

A cron job may pin its own reasoning effort, independent of global config.
Contract under test:

- Job store (cron/jobs.py): the field is validated at the storage choke
  point against the canonical Hermes effort grammar (parse_reasoning_effort
  in hermes_constants — the SAME parser every other effort surface uses).
  Garbage never persists; absent field keeps the job record byte-identical
  to pre-feature behavior. Capability clamping (xhigh on a model that caps
  at high, etc.) is intentionally NOT validated here — that is owned by the
  provider transports at send time, same as config-set effort.
- Scheduler resolution (cron/scheduler.py::_resolve_job_reasoning_config):
  a job-pinned effort wins outright over BOTH the global
  agent.reasoning_effort and per-model agent.reasoning_overrides; an absent
  field yields a result byte-identical to resolve_reasoning_config(cfg,
  model); a garbage value in a hand-edited store warns and falls back to
  config resolution instead of killing the tick.
