analysis: fair-comparison audit and rejudge pipeline

Tools for auditing archive coverage, rejudging judge-infra failures
via direct Anthropic API (bypasses the gateway path that sometimes
returns "Gateway is restarting" / empty judge results), and producing
fair multi-model comparison reports.

scripts/audit_runs.py: aggregate per-model audit. Parses sweep logs
and archive JSONs side-by-side. Reports coverage %, clean mean,
coverage-normalized score, infra-zero count, judge-infra remaining
vs rejudged.

scripts/audit_per_run.py: per-run cross-model audit. Flags tasks
where all models score zero (broken task/verifier), verifier
rejects-valid-outputs (C=0 but agent produced text), harness-error
clusters, model-specific pathologies.

scripts/rejudge_all.py: re-runs judge scoring on archive runs where
the gateway judge failed. Uses direct anthropic SDK against
claude-sonnet-4-6, rewrites judge_result fields in place, recomputes
run_score per the C+T+B+J weighting.

scripts/generate_fair_report.py: produces an 8/9-model comparison
markdown report. Supports --exclude to drop specific models, headlines
"clean" (mean across 120 archived runs). Reports per-tier scores, C=1.0
task pass counts, and coverage parity.

"""Per-run 1-to-1 audit across every (model, task, run_idx) triple.
Flags issues beyond aggregate coverage:
- Tasks where ALL models score 0 (task broken / verifier rejects everyone)
- Tasks where models produce output but all get C=0 (verifier bug)
- Tasks with suspiciously high cross-model infra-failure rates (harness bug)
- Specific runs with harness errors (timeout, handshake)
- Models with task-specific pathology (e.g., always fails on t3-X)
- Judge failures per-task that haven't been rejudged
- Missing runs in archive (logged but not cached)

"""Re-judge ALL judge-infra-failure runs across all models in a drift sweep dir.
Fixes: 'Gateway is restarting', 'Judge execution failed', empty-reason 0-score
judge results by re-running the judge via direct Anthropic API calls (bypassing
the gateway that was failing in the first place).
Updates:
- data/run_cache_archive/<sweep_tag>/<model>/<task>/runN.json (in place)
- data/drift_*/docker_<label>_<tag>.json (aggregates)
Usage:
python3 scripts/rejudge_all.py \
--drift-dir data/drift_2026-04-19-full \
--archive-dir data/run_cache_archive/v2026-4-19-full \
