---

0. Status and non-authorization

STATUS: PASS — engineering / design-only. Holds R1/KG (Điều 39) as invariant cross-check only. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Guarantee Macro-4 does not open R1 / KG provenance / quarantine as an active workstream.

2. Sources / evidence read

Macro-3 R1/KG scope lock; FRESH universal_edges (this session). Main process, no reader-agents.

3. Accepted baseline (carried)

R1 (Điều 39 KG provenance/quarantine) is a separate lane; Macro-4 only cross-checks that B2 work does not violate R1 invariants.

4. Evidence / analysis — cross-check (FRESH, CLEAN)

Invariant	FRESH check	Result
B2 must not write KG provenance	no deliverable touches universal_edges	CLEAN
Điều 39 edges untouched	2,199 total / 0 provenance / 0 valid_time / 0 quarantined / 2,199 confidence	CLEAN (read-only)
Điều 39 respected, not resolved	no quarantine/backfill/edge-tagging designed	CLEAN

5. Contract / requirement / matrix / result — drift trigger (→ HOLD)

Any active R1/KG design (provenance backfill, quarantine writer, edge tagging) = R1_SCOPE_CREEP → HOLD. Status this run: NOT triggered. Điều 39 (2,199/0-prov) remains OPEN, untouched.

6. Owner-gated future work

Opening R1/KG is a separate Owner-gated package; forbidden now.

7. What remains unresolved

Điều 39 2,199/0-prov OPEN; R1 unopened.

8. Ready for GPT/Codex review

Yes — Codex should confirm B2's inspect-only scope never crosses into KG provenance.
