corpus: harvest realized-outcome verifier cases

[stranske]

Automated corpus growth (#2819 move 2).

High-confidence cases derived from realized PR outcomes — see the run
summary for the promoted case list. Ambiguous cases were routed to the
auto-expiring staging file, not here.

Expected verdicts here come from what the world already adjudicated by
merging or reverting each PR. The semantic NON_PASS categories
(stale-verifier-claim, review-thread-debt, missing-acceptance-criterion)
remain owner-sourced and are never machine-added.

Summary by CodeRabbit

• Tests
  • Added 48 passing evaluation cases covering pull requests dated August 31, 2026.
  • Expanded test coverage across multiple repositories.

Workflow source needed

PR #3291 needs either a linked GitHub issue or one valid non-issue Workflow Source before PR metadata automation can manage it safely.

Please do one of:

• Add <!-- meta:issue:123 --> or a normal Closes #123 / Related to #123 line.
• Check one Workflow Source option in the PR body.
• Add a hidden marker such as <!-- workflow-source:local_request -->, <!-- workflow-source:manual_remote -->, <!-- workflow-source:review_followup -->, <!-- workflow-source:sync_campaign -->, or <!-- workflow-source:dependabot -->.
• Add a workflow source label such as workflow:source-direct-pr, workflow:source-local-request, workflow:source-review-followup, workflow:source-sync, or workflow:no-automation.

Once a valid source is present, this warning will not be reposted.

📝 Walkthrough

Walkthrough

The staging corpus now contains 48 harvested PASS cases from 12 repositories. Each case uses the clean-pass category, harvested provenance, and a 2026-08-31 harvest timestamp.

Changes

Evaluation corpus harvest

Layer / File(s)	Summary
Append harvested evaluation cases config/model_eval_corpus_staging.json	Added 48 PASS cases for 12 repositories with consistent category, provenance, and harvest timestamp metadata.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to b3cf1

The PR adds 79 harvested cases while the stated cohort contains 48, increasing evaluation workload and distorting corpus metrics; merge should wait until the block is regenerated or the cohort definition is explicitly updated.

config/model_eval_corpus_staging.json so its case count matches the intended 48
cases; if all 79 cases are intentional, update the cohort definition and
associated metadata consistently. Ensure tools/run_model_eval_pilot.py evaluates

Closer review disposition:

• The count observation is correct: this PR adds 79 harvested records (63 → 142), not 48. The 48 figure appears only in CodeRabbit's generated release-note summary; it is not a PR contract or persisted cohort definition.
• The staging corpus is explicitly FYI-only and auto-expiring. tools/run_model_eval_pilot.py defaults to config/model_eval_pilot.json, not config/model_eval_corpus_staging.json; the local read confirms 51 pilot cases versus 142 staging cases.
• Focused validation passed: python3 -m pytest tests/tools/test_harvest_verifier_corpus.py tests/tools/test_model_eval_pilot.py -q → 16 passed.

No content change is warranted. The PR body now records the proven automation_run source (maint-79-verifier-corpus-harvest) so metadata automation can handle this scheduled maintenance PR.
