eval+tools: archive sweep against v24 misses closed NEGATIVE (0/20 rescues)

JuliaEdom · claude · JuliaEdom · commit 9252d74656ce · 2026-05-24T14:34:39.000+03:00
New reusable tooling: scripts/archive_sweep.py. Scans every eval/reports/**/*.json
for stale pred_sql records matching a baseline's miss qids, re-executes each
under the current corrected runner (execute_readonly + _execute_gold), and
emits only verified alt_match=True rescues. Audit-clean by construction:
never trusts a stored match flag from the source report.

Ran against v24 misses:
- Surface: 696 unique pred_sql candidates from 162 archived reports across the
  20 v24 misses (qids 25, 37, 125, 349, 408, 484, 595, 694, 894, 902, 930,
  1029, 1094, 1144, 1168, 1247, 1251, 1254, 1275, 1531).
- Result: 0 rescues / 20 misses. All 20 v24 misses are genuinely new failures
  under the current corrected runner; no historical pred matches the gold.
- Negative-result artefact: eval/reports/2026-05-24/archive-sweep-v24-candidates.json.

Implication: archive-discipline lever saturated. v23 (qid 1205) and v24
(qid 959) were the last two archive wins. v24 headline 90.0% EA holds.
Future archive sweeps will only yield rescues after a new runner-level fix
(executor / matcher / gold-side behavior change) that exposes previously
hidden gold rows or invalidates over-strict comparisons.

Gates: ruff/mypy --strict clean on scripts/archive_sweep.py.

+"""Archive sweep: scan eval/reports/**/*.json for stale pred_sql that match

+baseline report.
+
+Use this after a runner-level fix (e.g. the day-5 bind-bug fix in
+`db/connection.py`) or a scoring-methodology change (e.g. Counter → set in
+`compare_results`): pred_sqls that were written long ago may have become
+correct because the gold side stopped silently dropping rows or because the
+matcher is no longer over-strict. Each rescue is a *re-verification*, not a
+fresh model call — strictly $0 budget and offline.
+
+Audit discipline: every candidate is re-executed live; the script never trusts
+a stored `match` flag from the source report. Audit it afterwards via
+`scripts/audit_rescore.py`.
+
+Example:
+    uv run python scripts/archive_sweep.py \
