distillation: audit-FULL pipeline port (phases 0/3/4) — cross-runtime metric parity verified
Ports the metric-collection passes from scripts/distillation/audit_full.ts.
The substrate that PRODUCES audit_baselines.jsonl entries — the
half OPEN #2 left as "deferred to next wave" after the read/write
substrate landed in ca142b9.
Phase coverage:
Phase 0 (file presence) ported
Phase 1 (schema validators) skipped (Go's `go test` covers it)
Phase 2 (materializer dry-run) deferred (Go materializer not yet ported)
Phase 3 (scored-runs distribution) ported
Phase 4 (contamination firewall) ported
Phase 5 (receipts validation) deferred (Go run-summary JSON not yet emitted)
Phase 6 (replay sanity) deferred (Go replay tool not ported)
Phase 7 (run summary lineage) deferred (same)
Cross-runtime parity verified end-to-end:
Go-side audit-full against /home/profit/lakehouse produced
metrics IDENTICAL to the last Rust-emitted audit_baselines.jsonl
entry. All 8 ported metrics match byte-for-byte:
p3_accepted=386, p3_partial=132, p3_rejected=57, p3_human=480,
p4_sft_rows=353, p4_rag_rows=448, p4_pref_pairs=83, p4_total_quarantined=1325
6/6 required checks pass on live data.
Components:
- internal/distillation/audit_full.go: PhaseCheck struct (mirrors
Rust shape), PhaseCheckReport aggregation, RunAuditFull
orchestrator, auditPhase0/3/4 implementations, FormatAuditFullReport
Markdown writer.
- cmd/audit_full/main.go: CLI binary with -root, -out, -json,
-append-baseline flags. Operators run "./bin/audit_full
-append-baseline" to grow the longitudinal log alongside the
Rust pipeline (entries are interchangeable — same envelope shape).
- 6 new tests: empty-root failure handling, full-fixture clean PASS
(locks all 8 metrics + all 6 required checks), SFT firewall
contamination detection, preference self-pair detection, sig_hash
regex correctness (rejects wrong-length + uppercase), Markdown
formatter smoke.
Live-data probe captured at reports/cutover/audit_full_go_vs_rust.md
(linked from reports/cutover/SUMMARY.md). Same shape as the
audit_baselines round-trip evidence — both Go-side ports of the
distillation surface are now validated against real Rust data, not
just fixtures.
