R1-invariant lock. R1/KG is used only as an invariant cross-check. No KG backfill, edge-provenance repair, quarantine, Qdrant-provenance, or KG runner work is opened. If R1/KG becomes an active workstream, that is
R1_SCOPE_CREEP→ HOLD.
0. Status and non-authorization
STATUS: PASS — engineering / read-only. Cross-check CLEAN: the B2/staging/channel work touches none of S3/S4, the KG edge store, provenance, quarantine, Qdrant, or the KG runner; the Đ39 provenance invariant is respected (B2 writes no edges), re-confirmed fresh. Engineering PASS ≠ authority PASS. Default disposition: HOLD. No KG work opened; no edge/provenance/quarantine write; no DB write/DDL/DML; no TD; no blocker resolved.
Evidence basis — FRESH_READONLY_EVIDENCE (FQ-12) + INHERITED_KB_EVIDENCE (KG substrate detail; X-1…X-9). Reading discipline: main process, no reader-agents.
1. Purpose
Answer macro question 8: do R1/KG invariants remain untouched? §4 records the fresh edge/provenance readback; §5 carries the X-1…X-9 cross-check (CLEAN).
The one rule: the birth lane (B2/staging/channel) shares zero write surface with the KG lane; they converge only at S1 (Điều 32) and S5/S6 — neither reached by this read-only evidence macro. The Đ39 invariant is respected here, resolved nowhere here.
2. Sources / evidence read
Deliverable 1 (FQ-12); Mega Gate R1/KG Invariant Cross-Check (X-1…X-9); R2a/R1a (KG substrate: 2199 edges / 0 provenance; KG REGISTERED_NOT_EXECUTED); Phase-1B (Đ39 invariant unmet, R1 lane). Read directly, main process.
3. Accepted baseline (carried)
X-1…X-9 (Mega Gate): B2 touches no S3/S4; writes no KG provenance; no KG backfill/quarantine/Qdrant/runner work; Đ39 invariant ("Edge PHẢI có provenance") respected (B2 writes no edges); birth lane independent of KG lane (AC-7). universal_edges 2199 / 0 provenance (INHERITED).
4. Read-only evidence observed (FRESH, 2026-06-18)
- FQ-12 —
universal_edges: 2,199 total; 0 with provenance — the Đ39 invariant remains unmet on the live edge store (FRESH-confirmed; identical to inherited). This is an R1-lane fact; the birth lane writes no edges, so it cannot violate the invariant. - B2/staging/channel write nothing here: this run performed only SELECT/catalog reads +
list_docker; it wrote no edge, no provenance, no quarantine, no S3/S4 identity/canonical, no Qdrant. - Shared-channel guard: the agent-api executor (a candidate B2 channel) is bound only to the 2 KG-EXPLAIN contracts (FQ-18); a future birth binding must be per-DOT so the lanes stay decoupled (X-7).
5. Classification / result — X-1…X-9 cross-check (CLEAN)
| # | Invariant | Status | Evidence |
|---|---|---|---|
| X-1 | B2 doesn't touch S3 (identity) | CLEAN | B2 reads, never mints (design) |
| X-2 | B2 doesn't touch S4 (canonical) | CLEAN | FQ-1 (B2 writes inspect_* only; canonical_address present but B2 never writes it) |
| X-3 | no KG provenance write | CLEAN | this run wrote nothing |
| X-4 | no KG backfill designed | CLEAN | not opened |
| X-5 | no quarantine implemented | CLEAN | not opened |
| X-6 | no Qdrant-as-provenance | CLEAN | not opened |
| X-7 | no graph authority / KG runner work; per-DOT channel | CLEAN | FQ-18 (executor 0 birth-bound; KG-EXPLAIN only) |
| X-8 | Đ39 invariant not violated | CLEAN | FQ-12 (2199/0-prov is R1-lane; B2 writes no edges) |
| X-9 | birth lane independent of KG lane (AC-7) | CLEAN | design + FQ-18 |
Cross-check verdict: CLEAN. R1_SCOPE_CREEP not triggered; the Đ39 invariant is respected here and resolved nowhere here (that is the separate R1 macro).
6. Owner-gated future work (R1-lane — referenced only, not opened)
| Future R1 work (NOT opened) | Gate required | Forbidden now? |
|---|---|---|
| Recover provenance SoT (K3) | external S6 | Yes |
| Backfill edge provenance (K4) | Điều 32 + S5 + K3 | Yes |
| Build quarantine (K5) | Điều 32 | Yes |
| Enforce the Đ39 invariant | separate R1 macro | Yes |
7. What remains unresolved
- Đ39 invariant unmet on the live edge store (2199/0-prov, FRESH) — respected by B2, not resolved here.
- R1/KG cross-check only; no KG work opened.
- Blockers — all OPEN.
8. Ready for GPT/Codex review
Yes — as a read-only R1/KG invariant cross-check.
Core rule: the birth lane touches no KG surface; universal_edges 2199/0-prov (FRESH) is an R1-lane fact the birth lane cannot violate; cross-check CLEAN; no KG work opened or resolved.
Default disposition: HOLD. Engineering PASS ≠ authority PASS. All blockers remain OPEN.
