lakehouse/auditor 17 blocking issues: cloud: claim not backed — "Verified end-to-end via playwright on devop.live/lakehouse:"
Phase 6 acceptance + Phase 8 full-audit reports re-run; bit-for-bit
reproducibility property still holds (run 1 hash == run 2 hash),
just at a new value.

Meta-audit script that runs deterministic checks across Phases 0-7
and compares to a baseline (auto-grown from prior runs). Pure
observability — no pipeline modification. Single command:
./scripts/distill audit-full
Files (2 new + 1 modified):
scripts/distillation/audit_full.ts ~430 lines, 8 phase checks + drift
scripts/distillation/distill.ts +audit-full subcommand
reports/distillation/phase8-full-audit-report.md (autogenerated by run)
Real-data audit on commit 681f39d:
22 total checks, 16 required, ALL 16 required PASS.
Per-phase (required-pass / required):
P0 recon: 1/1 — docs/recon/local-distillation-recon.md + tier-1 streams
P1 schemas: 1/1 — 51 schema tests pass via subprocess
P2 evidence: 1/1 — materializer dry-run completes
P3 scoring: 1/1 — acc=386 part=132 rej=57 hum=480 on disk
P4 exports: 5/5 — SFT 0-leak + RAG 0-rejected + Pref 0 self-pairs +
0 identical-text + 0 missing provenance
P5 receipts: 4/4 — 5/5 stage receipts, all validate, RunSummary valid,
run_hash is sha256
P6 acceptance: 1/1 — 22/22 fixture invariants pass via subprocess
P7 replay: 2/2 — 3/3 dry-run tasks pass + escalation guard holds
Drift detection (auto-grown baseline at data/_kb/audit_baselines.jsonl):
10 tracked metrics across P2/P3/P4 + quarantine totals.
This run vs first audit baseline: 0% drift on all 10 metrics.
Future drift >20% on any metric flips flag from ok → warn.
Non-negotiables:
- DO NOT modify pipeline logic — audit only reads + calls scripts
- DO NOT suppress failures — non-zero exit on any required-check fail
- DO NOT fake pass conditions — checks are deterministic + assertive
Bug surfaced during construction (matches the spec's "spec is honest"
gate): P3 check first used scoreAll dry-run which reported 0 accepted
because scored-runs were deduped against. Fixed by reading
data/scored-runs/ directly to get the on-disk distribution. Same
class of bug as the audits.jsonl recon mistake from Phase 3 — assume
nothing about a stream, inspect what's there.
Phase 8 done-criteria (per spec):
✓ audit command runs successfully
✓ all 8 phases verified (P0..P7)
✓ drift clearly reported (10-metric drift table per run)
✓ report exists (reports/distillation/phase8-full-audit-report.md)
What this unlocks:
Subsequent CI / cron runs of audit-full will surface real drift if
the pipeline's behavior changes. The system is now self-monitoring
in the strongest sense: every invariant has an automated check,
every metric has a drift gate, and the report tells a future agent
exactly what diverged.
