| # Phase 4 audit completion — 23 October 2026 | |
| All **150 judgments are complete and scored**, under amendment | |
| `P4-AI-AUDIT-2026-10-23`. These are **AI-reviewed; not independently | |
| human-validated**. They must not be described as human or fully blind judgments. | |
| | Condition | Clone | Not clone | Unsure | AI-reviewed rate; not independently human-validated | Wilson 95% | Rate including unsure | | |
| |---|---:|---:|---:|---:|---|---:| | |
| | C4: filtered BM25 | 6 | 42 | 2 | 12% | 5.6–23.8% | 16% | | |
| | C5: filtered random | 0 | 50 | 0 | 0% | 0–7.1% | 0% | | |
| | C6: filtered semantic | 11 | 38 | 1 | 22% | 12.8–35.2% | 24% | | |
| Wilson intervals quantify sampling uncertainty only. They do not account for | |
| AI-review error, shared systematic mistakes, or knowledge of benchmark outcomes. | |
| There is one AI reviewer and no measured inter-rater agreement. | |
| ## What the results permit | |
| - C4 is below the registered 42% ceiling but not contamination-free. The voided | |
| C3=C4 same-rate comparison is removed, not restored. | |
| - C5's point estimate is within the predicted 0–2% band. Zero observed clones | |
| does not demonstrate that its population contamination is at most 2%; its | |
| sampling upper limit is 7.1%. Keep C1 as the report/demo headline condition. | |
| - C6's point estimate is below the predicted 25–35% band, but its interval | |
| overlaps that band. Neither mechanism explanation is independently confirmed. | |
| Retain the observed scorer/F1 rescue; withdraw the stronger claim that it | |
| isolates similarity from contamination dose. | |
| The original numeric bands and scorer-state-first endpoint ordering are | |
| unchanged. Comparisons to earlier human C2/C3 audits use different reviewer | |
| methods and cannot be treated as controlled contamination comparisons. | |
| ## Evidence and verification | |
| The completed CSVs (`phase4_ai_review_c4.csv`, `phase4_ai_review_c5.csv`, | |
| `phase4_ai_review_c6.csv`) contain one pair-specific functional rationale and | |
| reviewer/amendment attribution per judgment. The original blank pack is retained. | |
| Labels were frozen at **2026-10-23 11:38:33 UTC**, before joining audit keys or | |
| calculating rates. `phase4_ai_audit_freeze.json` commits their SHA-256 hashes. | |
| `phase4_ai_audit_protocol.json` preserves the original pre-label amendment, | |
| including its historical pending status; this completion report supersedes that | |
| status without changing the committed protocol file. | |
| For each condition, all 50 IDs exactly match the fixed sheet and reproduce its | |
| seed-13 sample; all keys match current mining triples. Result provenance records | |
| the label, sheet, protocol and freeze hashes. Score-bound outcome records are | |
| in `sanitycheck.md` §9.9. Modified scoring refuses altered frozen labels, | |
| missing rationales and missing AI attribution in the amended closure gate. | |
| Additionally, all **300 code fragments** match the key-indexed canonical corpus | |
| text. The focused audit/scoring and closure suite passed **23 tests** (three | |
| unrelated evaluation/checkpoint tests were deselected locally). This is separate | |
| from the earlier 165-test Colab run; no new full-suite pass is claimed. | |
| The audit is complete. Full-project closure additionally requires reconciliation | |
| of the combined benchmark/generalisation table and remaining paper claims; | |
| audit completion alone is not proof those separate tasks are finished. | |
