"""Phase 1 smoke test — verifies the "no more mock" invariants.

Run this AFTER backend Phase 1 ship completes:
* ``polyglot_alpha/chain/`` package wired into the auction path,
* ``polyglot_alpha/agents/dispatch.py`` dispatching 4 real LLM agents,
* orchestrator + ``/trigger/event`` accepting ``event_source='rss'`` and
  emitting real BLEU/COMET/MQM and real or dry-run Polymarket submissions.

Each individual check is best-effort: a failure logs and the rest still
run, then the script writes ``outputs/smoke_test_phase1_result.json``
with a structured summary so CI / downstream agents can post-process.

Exit codes:

* ``0`` — every check passed.
* ``1`` — backend unreachable or some checks failed (see JSON for detail).
