Reviewer Path

Start here:

1. Run python3 scripts/smoke_test.py.
2. Run python3 scripts/scan_identity.py.
3. Run python3 scripts/score_contract.py examples/toy_predictions.jsonl examples/toy_targets.jsonl to inspect answer parsing, box parsing, IoU, and Joint@0.5 mechanics on redistribution-safe toy rows.
4. Run python3 scripts/recompute_bootstrap.py and python3 scripts/recompute_failure_taxonomy.py to summarize reviewer-safe validation exports.
5. Open croissant.json and metadata/rai_metadata.json.
6. Inspect the frozen contract in eval/frozen_downstream_eval_20260322/contract.json.
7. Inspect paper-facing table exports under eval/frozen_downstream_eval_20260322/analysis_20260326/paper_tables/.
8. Inspect paired uncertainty in eval/frozen_downstream_eval_20260322/analysis_20260326/bootstrap_report.md and pairwise_branch_comparisons.csv.
9. Inspect tradeoff/failure summaries in analysis/failure_taxonomy_primary_residual.csv.
10. Inspect endpoint harshness diagnostics in analysis/endpoint_diagnostics/.

The core branch comparison should be read as a within-contract measurement problem. Joint@0.5 is an intentionally strict exact-answer/single-box endpoint; it supports paired comparison under a frozen contract, not a calibrated clinical endpoint.

The primary residual is source-ID-disjoint from the visible-rationale pool but is not verified at patient/study level. The supplemental VinDr diagnostic is not training-disjoint and is included only as a source-coverage diagnostic.
