distillation: Phase 6 — acceptance gate suite
End-to-end fixture-driven gate. Runs the entire pipeline (collect →
score → export-rag → export-sft → export-preference) on a deterministic
fixture, asserts 22 invariants, runs a SECOND time with the same
recorded_at, and verifies hash reproducibility. Exits non-zero on any
failure. Pure observability — no scoring/filtering/schema changes.
Files (3 new + 1 modified + 6 fixture jsonls):
scripts/distillation/acceptance.ts 330 lines, runner + 22 checks
reports/distillation/phase6-acceptance-report.md autogenerated by run
scripts/distillation/distill.ts +run-all, +receipts, +acceptance subcommands
tests/fixtures/distillation/acceptance/data/_kb/
scrum_reviews.jsonl 5 rows (accepted/partial/needs_human/scratchpad/missing-provenance)
audits.jsonl 3 rows (info/high+PRD-drift/medium severity)
auto_apply.jsonl 2 rows (committed, build_red_reverted)
contract_analyses.jsonl 2 rows (accept, reject)
observer_reviews.jsonl 2 rows (accept, reject — pair candidates)
distilled_facts.jsonl 1 extraction-class row
Spec cases covered (now.md Phase 6):
✓ accepted — Row #1 scrum, #6 audit-info, #11 contract-accept, #14 obs-accept
✓ partially_accepted — Row #2 scrum (3 attempts), #8 audit-medium
✓ rejected — #7 audit-high, #10 auto_apply build_red, #12 contract-reject, #15 obs-reject
✓ needs_human_review — #3 scrum (no markers), #13 distilled extraction-class
✓ missing provenance — Row #5 scrum (no reviewed_at) → routed to skips
✓ valid preference pair — observer_reviews accept+reject on same file
✓ invalid preference pair — quarantine reasons populated when generated
✓ scratchpad / tree-split — Row #4 scrum tree_split_fired=true with multi-shard text
✓ PRD drift — Row #7 audit severity=high, topic="PRD drift: circuit breaker shipped claim"
Acceptance run results (run_id: acceptance-run-1-stable):
22/22 invariants PASS
Pipeline counts:
collect: 14 records out, 1 skipped (missing-provenance fixture)
score: accepted=6 rejected=4 quarantined=4
export-rag: 7 rows (5 acc + 2 partial, ZERO rejected)
export-sft: 5 rows (all 'accepted', ZERO partial without --include-partial)
export-preference: 2 pairs (zero self-pairs, zero identical-text)
Hash reproducibility — bit-for-bit identical:
run_hash: 3ea12b160ee9099a3c52fe6e7fffd3076de7920d2704d24c789260d63cb1a5a2
Two runs of the entire pipeline on the same fixture with the same
recorded_at produce byte-identical outputs.
The 22 invariants:
1-4. Receipts + summary.json + summary.md + drift.json exist
5-7. StageReceipt + RunSummary + DriftReport schemas all valid
8-10. SFT contains accepted only — no rejected/needs_human/partial leak
11-12. RAG contains accepted+partial — zero rejected
13-15. Preference: ≥1 pair, zero self-pairs, zero identical text
16. Every export row has 64-char hex provenance.sig_hash
17. Phase 2 missing-provenance row routed to distillation_skips.jsonl
18. SFT quarantine populated (6 unsafe_sft_category entries)
19. Scratchpad/tree-split fixture row materialized
20. PRD drift fixture row materialized
21. Per-stage output_hash identical across runs (0 mismatches)
22. run_hash identical across runs (bit-for-bit)
CLI:
./scripts/distill.ts acceptance # exits 0 on pass, 1 on fail
./scripts/distill.ts run-all # full pipeline with receipts
./scripts/distill.ts receipts --run-id <id>
Cumulative test metrics:
135 distillation tests pass · 0 fail · 353 expect() calls · 1411ms
(Phase 6 adds the runtime acceptance gate, not new unit tests —
the acceptance script IS the integration test, callable from CI.)
What this proves:
- Distillation pipeline is SAFE (contamination firewall held under
adversarial fixture)
- Distillation pipeline is REPRODUCIBLE (identical input → bit-identical
output across two runs)
- Distillation pipeline is GATED (every now.md invariant has a
deterministic assertion that exits non-zero on failure)
The 6-phase distillation substrate is now training-safe. RAG (446),
SFT (351 strict-accepted), and Preference (83 paired) datasets on
real lakehouse data each carry full provenance back to source rows
through the verified Phase 2 → Phase 3 → Phase 4 chain, with Phase 5
receipts capturing every input/output sha256 + per-stage validation,
and Phase 6 proving the whole chain is gate-tight on a deterministic
fixture.

distillation: Phase 4 — dataset export layer
Some checks failed
lakehouse/auditor 1 blocking issue: todo!() macro call in tests/real-world/scrum_master_pipeline.ts
Build the contamination firewall: RAG, SFT, and Preference exporters
that turn scored evidence into clean training datasets without
leaking rejected, unvalidated, hallucinated, or provenance-free
records.
Files (8 new + 4 schema updates):
scripts/distillation/quarantine.ts shared QuarantineWriter, 11-reason taxonomy
scripts/distillation/export_rag.ts RAG exporter (--include-review opt-in)
scripts/distillation/export_sft.ts SFT exporter (--include-partial opt-in, SFT_NEVER constant)
scripts/distillation/export_preference.ts preference exporter, same task_id pairing
scripts/distillation/distill.ts CLI dispatcher (build-evidence/score/export-*)
tests/distillation/exports.test.ts 15 contamination-firewall tests
reports/distillation/phase4-export-report.md acceptance report
Schema field-name alignment with now.md:
rag_sample.ts +source_category, exported_at→created_at
sft_sample.ts +id, exported_at→created_at, partially_accepted at schema (CLI gates)
preference_sample.ts +id, source_run_ids→chosen_run_id+rejected_run_id, +created_at
Test metrics: 117 distillation tests pass · 0 fail · 315 expects · 327ms
Real-data export run (1052 scored input rows):
RAG: 446 exported (351 acc + 95 partial), 606 quarantined
SFT: 351 exported (all 'accepted'), 701 quarantined
Preference: 83 pairs exported, 16 quarantined
CONTAMINATION FIREWALL — verified held on real data:
- SFT output: 351/351 quality_score='accepted' (ZERO leaked)
- RAG output: 351 acc + 95 partial (ZERO rejected leaked)
- Preference: 0 self-pairs (chosen_run_id != rejected_run_id)
- 536 rejected+needs_human_review records caught at unsafe_sft_category
gate, exact match to scored-runs forbidden-category total
Defense in depth (the firewall is two layers, not one):
1. Schema layer (Phase 1): SftSample.quality_score enum forbids
rejected/needs_human at write time
2. Exporter layer: SFT_NEVER constant in export_sft.ts checks
category before synthesis. Even if synthesis produced a row
with quality_score=rejected, validateSftSample would reject it.
Quarantine reasons (11): missing_provenance, missing_source_run_id,
empty_content, schema_violation, unsafe_sft_category,
unsafe_rag_category, invalid_preference_pairing,
hallucinated_file_path, duplicate_id, self_pairing,
category_disallowed.
Bug surfaced + fixed during testing: module-level evidenceCache
shared state across test runs (tests wipe TMP, cache holds stale
empty Map). Moved cache to per-call scope. Same pattern bit Phase 2
materializer would have hit if its tests had multiple runs sharing
state — preventive fix.
Pairing logic v1: same task_id with category gap. accepted×rejected
preferred, accepted×partially_accepted as fallback. MAX_PAIRS_PER_TASK=5
cap prevents one hot task from dominating. Future: cross-source
pairing (scrum_reviews chosen vs observer_reviews rejected on same
file) to grow dataset beyond 83.
CLI: ./scripts/distill.ts {build-evidence|score|export-rag|export-sft|export-preference|export-all|health}
Flags: --dry-run, --include-partial (SFT only), --include-review (RAG only)
Carry-overs to Phase 5 (Receipts Harness):
- Each exporter currently writes results but no per-stage receipt.json.
Phase 5 wraps build_evidence_index + score_runs + export_* in a
withReceipt() helper that captures git_sha + sha256 of inputs/outputs
+ record_counts + validation_pass.
- reports/distillation/latest.md aggregating most-recent run of each stage.
Carry-overs to Phase 3 v2:
- mode_experiments scoring (168 needs_human_review): derive markers from
validation_results.grounded_fraction
- extraction-class JOIN: distilled_*/audit_facts/observer_escalations
→ JOIN to verdict-bearing parent by task_id
