## Requirement Details

### DPO-01 — PASS

selfAudit() returned score=1 (float in [0,1]), constraints.length=6 (6 CLAUDE.md constraints). selfAuditAndLog() wrote self-score-log.jsonl to /var/folders/yw/2qhx3yzj0psf87rdxh8lqlmm0000gp/T/prove-rlaif-JPyvUu. Log entry: feedbackId=proof-dpo01, score present. Module: scripts/rlaif-self-audit.js. No API calls — pure heuristic evaluation.

### DPO-02 — PASS

dpoOptimizer.run() completed: pairs_processed=0. dpo-model.json written to /var/folders/yw/2qhx3yzj0psf87rdxh8lqlmm0000gp/T/prove-dpo02-0xn4Z6. Model fields: generated=2026-03-04T20:27:39.727Z, pairs_processed=0. adjustments={}. Module: scripts/dpo-optimizer.js. dpoLogRatio range: [-1, +1]. Pure offline batch optimization.

### DPO-03 — PASS

extractMetaPolicyRules() produced 1 rule(s) from 3 seeded negative entries. meta-policy-rules.json written to /var/folders/yw/2qhx3yzj0psf87rdxh8lqlmm0000gp/T/prove-dpo03-O1D5YZ. Rules: [{"category":"testing","confidence":0.661,"trend":"stable","count":3}]. All rules have required fields: category, confidence, trend, occurrence_count. Module: scripts/meta-policy.js. MIN_OCCURRENCES threshold: 2.

### DPO-04 — PASS

node --test (3 RLAIF test files): pass=24, fail=0. Phase 4 baseline (test:api): 93 tests. Phase 5 adds 24 new RLAIF tests. Total with RLAIF: 117 tests (node-runner only). Files: tests/rlaif-self-audit.test.js (selfAudit, selfAuditAndLog), tests/dpo-optimizer.test.js (dpoLogRatio, buildPreferencePairs, run, applyDpoAdjustments), tests/meta-policy.test.js (extractMetaPolicyRules, run). All tests use tmpdir pattern — zero production feedback dirs touched.

## Test Count Delta

| Baseline (Phase 4 test:api) | Phase 5 RLAIF Addition | Total (node-runner) |
|----------------------------|------------------------|---------------------|
| 93 node-runner tests | +24 RLAIF tests (3 test files) | 117 |

Phase 5 (plan-03) added RLAIF test coverage:
- `tests/rlaif-self-audit.test.js` — CONSTRAINTS, selfAudit(), selfAuditAndLog()
- `tests/dpo-optimizer.test.js` — dpoLogRatio(), buildPreferencePairs(), run(), applyDpoAdjustments()
- `tests/meta-policy.test.js` — extractMetaPolicyRules(), run()

All tests use `fs.mkdtempSync()` tmpdir isolation. Zero production feedback dirs touched.
