"""E2E integration — the full curate machinery (deterministic, offline) + an opt-in LIVE stack run.

The offline test mocks the gateway so the WHOLE two-stage curate path runs in CI: Opus-score JSON →
rubric.aggregate → calibration → floor filter → best-first sort → Haiku prose merge. It asserts the
contract that matters: an aligned job reaches the 90s, a weak job is DROPPED at the floor, and every
surviving match decomposes to real evidence.

The live test (RUN_LIVE_E2E=1) runs the real new stack + Opus/Haiku — documents the manual verification
(sweep → ~133 jobs incl. TimesJobs full-signal → scores reach 96).
