Owner

Purpose

Execute the owner-approved re-score of the public claim manifest with the current analyzer. The decision was recorded 2026-09-02 in docs/research/ko-gpt-miss-review-step1-decision-20260902.md ("left as an owner decision"); the owner took it on 2026-09-16. Deterministic only — no model calls, no network, no keys; no analyzer/threshold code changes.

What changed

  • artifacts/rebaseline-2025/rebaseline-2026.scored.public.jsonl — regenerated via node scripts/rebaseline-build-claim-manifest.mjs (default paths; private inputs staged locally, never committed). 800 records, claim-ready.
  • docs/benchmarks/rebaseline-latest.{md,json} — regenerated via npm run benchmark:rebaseline:report.
  • Dated amendments appended (append-only) to ko-gpt-miss-review-step1-decision-20260902.md and 2026-rebaseline.md; historical tables untouched.

Every changed figure (old → new)

TP/FP/FN/TN 404/32/196/168 411/22/189/178

Carryover verification (mandatory check — PASS)

Miss set of the ko gpt-family cell under the new score vs the 48 reviewed text_hashes of ko-gpt-miss-review.v1.jsonl: identical sets — 48 vs 48, 0 in-new-not-reviewed, 0 in-reviewed-not-new. The blinded 2-reviewer step-1 evidence carries over unchanged; the 8 precondition-violated:document-hot exclusions are exactly the newly caught rows (44% + 8 = 52%).

Verification

npm run lint syntax/ESLint/tsc/CSpell/architecture all pass 0

Rollback

Revert this PR; the previous manifest and reports return byte-identical.

… analyzer

Owner-approved 2026-09-16 (decision recorded 2026-09-02). KO GPT-family
catch 44% -> 52%; miss set byte-identical to the 48 reviewed hashes, so
the step-1 blinded review carries over unchanged. All sibling-cell moves
reported in rebaseline-latest.md; historical tables amended append-only.
