research: Task 2 closed — SUE dead, earnings gap informational

Earnings backfill sourced from the public DoltHub earnings repo at a
pinned commit rather than the FMP API: reproducible for anyone re-running
the study, and it burns no request quota. 12,414 events, 98.6% of symbols
with >=8 announcements, 99.2% paired actual/estimate, no keyed duplicates.

2a earnings-gap diagnostic: INFORMATIONAL, no filter shipped. The
pre-earnings cohort's right tail was better, so the registered
avoid-earnings condition failed. Note the raw 23/266 vs 115/574 incidence
gap is largely a duration confound -- severe losses stop out fast and have
less time to span an announcement -- so it is not evidence that holding
through earnings is safe.

2b SUE: FAIL against the pre-registered +0.03 bar (unconditional IC
+0.0151 over 56 reliable windows, momentum-conditional +0.0213). Signs
stable across eras, so this is a clean null rather than an ambiguous one,
consistent with post-earnings drift having decayed in large caps.

Closes the Tier-1 arc: Task 1 dead on deep evidence, Task 2 dead here,
Task 3 complete as diagnostic. No in-sample research thread remains open.

"""Backfill historical earnings into a snapshot ``earnings_events`` table.
"""Bulk-only historical earnings backfill for a local SQLite snapshot.
Prefers FMP bulk date-range ``earnings-calendar`` (one request per window).
On free-tier 402/403, falls back to per-symbol ``/stable/earnings`` with
resume support and request counting (≈250 req/day free tier).
The job uses FMP's date-range earnings-calendar endpoint. One request covers all
symbols in a date window; per-symbol endpoints are intentionally not available
in this task runner. Successful windows are committed independently so a later
run resumes after a daily quota boundary without repeating completed windows.
Research only — writes to the local snapshot SQLite, never production Postgres.
Example
-------
python scripts/backfill_earnings_events.py \\
--snapshot backtest_snapshots/prod.sqlite --limit 250
Example:
python scripts/backfill_earnings_events.py --snapshot backtest_snapshots/prod.sqlite \
--from-date 2012-01-01 --window-days 30 --limit 250
