"""ENTRYPOINT #1 — the nightly research run.

Brings up oMLX, then runs the 3 personas strictly sequentially (one model, time-sliced),
each under a rollover wall-clock budget bounded by the hard stop. Every agent's output is
checkpointed to state/output/<trade_date>/. Run with --compressed for a fast end-to-end
test (short budgets).

    uv run python -m orchestration.run_nightly [--compressed]
