R1-invariant lock. This packet uses R1/KG only as an invariant cross-check — to confirm that nothing in the B2 / staging / channel work touches the R1-K provenance/KG lane. It opens no KG workstream: no KG backfill design, no edge-provenance repair, no quarantine implementation, no Qdrant-as-provenance logic, no KG runner work. If R1/KG becomes an active workstream here, that is
R1_SCOPE_CREEP→ HOLD.
0. Status and non-authorization
STATUS: PASS — engineering / design-only. This is a complete design-only R1/KG invariant cross-check: confirmation that B2 / staging / channel touch none of the R1-K surfaces (S3/S4 identity/canonical, the KG edge store, provenance, quarantine, Qdrant, the KG runner), that no Điều 39 provenance invariant is violated, and that the birth lane stays independent of the KG lane (AC-7).
Engineering PASS ≠ authority PASS. A PASS means the cross-check is complete on paper. It is not an Owner authorization to open any KG work; it opens none. Default disposition: HOLD.
Pipeline position (downstream-only). Deliverable 18 of the Mega Gate Bundle; it is the R1/KG invariant cross-check the macro requires (§9.5). It opens no KG workstream and resolves no R1 blocker.
Non-authorization (explicit). As Deliverable 1 §0, and specifically: it designs no KG backfill; repairs no edge provenance; implements no quarantine; writes no Qdrant-provenance logic; does no KG runner work. R1/KG is used as a cross-check only. v0.1/FIX7 V3 not overwritten; v0.2 not authority.
Evidence basis — INHERITED_EVIDENCE. No runtime queried. R1/KG facts inherited from R2a / R1a / the modular scoping / Phase-1B. AgentData metadata authoritative at read time. CAV-1/CAV-2 (R1-lane) carried for completeness; CAV-3/CAV-4/CAV-5 carried.
Reading discipline (Codex caveat, honored). All sources read directly from AgentData KB, bounded/sequential, by the main process — no parallel/background reader-agents, no sub-agents, no local-prose inference. /tmp = decode-scratch only, never SSOT.
1. Purpose
Confirm the macro's R1/KG invariant: B2 / staging / channel work does not touch the R1-K provenance/KG lane, and violates no Điều 39 provenance invariant. The packet answers:
- Does B2/staging/channel touch S3/S4 or the KG lane? — §5 (no).
- Is there any KG backfill / quarantine / Qdrant-provenance / graph-authority? — §5 (none).
- Is the Điều 39 provenance invariant respected (not violated, not enforced)? — §5.
- How does the birth lane stay independent of the KG lane (AC-7)? — §5.
The one rule, above all detail. The birth lane (R2-B / B2) and the KG lane (R1-K) share zero write surface at the design tier; they converge only at S1 (Điều 32) for writes and S5/S6 for materialization — neither reached by this design-only bundle. B2 writes only inspect_*; it touches no S3/S4, no edge provenance, no quarantine, no Qdrant, no KG runner. This packet confirms the separation; it opens no KG work.
2. Sources read
All 25 required sources read first-hand from AgentData KB, by the main process, sequentially; none SOURCE_NOT_READ (full list in Deliverable 20 §2). Used principally: the modular scoping (the 22-block map; K1–K7; AC-1…12; the cross-package zero-shared-write-surface claim); the interface packet §11 (no K-block touches S3/S4); R2a / R1a (the KG substrate: 2199 edges / 0 provenance; KG REGISTERED_NOT_EXECUTED); Phase-1B (Điều 39 invariant unmet; the R1 macro); the block-contract packet (AC-7; birth↔KG isolation guard).
3. Accepted baseline (carried, not re-derived)
- R1-K = the KG lane (provenance / quarantine / KG gates):
universal_edges= 2199 (2039LEGACY|S167H+ 160DIRECTUS), 0 provenance, 0 ever quarantined, edge creation stopped 2026-04-21; 36 KG DOTs, 1 contracted (DOT_KG_EXPLAINDRY_RUN), 0 REAL_RUN; 5 fail-closed gates; quarantine mechanism ABSENT;kg_quality_log=0; Qdrant (entity_embeddings) is vector/search, never provenance. - Điều 39 invariant (carried): "Edge PHẢI có provenance. Không provenance = quarantine." Unmet on the live edge store (PH1-F1, HIGH) — this is an R1-lane finding, not RISK-BYPASS (caveat C-1).
- Cross-package isolation (carried, modular scoping §12): R1-K and R2-B share zero write surface at the design tier; converge only at S1 (Điều 32/37) for writes and S5+S6 for materialization — neither reached by a design-only package. No K-block touches S3 or S4.
- AC-7 (carried): registry/pivot identity (S3) must not depend on KG reasoning; identity is structural and precedes inference. AC-4/AC-5/AC-6/AC-8 keep provenance/quarantine/Qdrant in the K-lane.
- Blockers — all OPEN. Tool/packet lock carried.
4. Analysis — cross-check, not workstream
R1/KG appears in this bundle for exactly one reason: to prove a negative — that the B2 path introduces no coupling to the KG lane and no violation of the Điều 39 provenance invariant. The risk being guarded is that a birth-lane producer, a staging surface, or a channel could quietly reach into the KG lane (e.g. a producer that "also tags provenance," a staging surface co-located with edges, a channel shared with the KG executor that couples the lanes). The cross-check below confirms none of that occurs. Crucially, this is not an R1 workstream: it designs no backfill, no quarantine, no Qdrant logic, no runner work — doing any of those would be R1_SCOPE_CREEP. The Điều 39 invariant is respected (not violated) here; it is neither enforced nor resolved (that is the separate R1 macro, Owner-gated).
5. R1/KG invariant cross-check
| # | Invariant to confirm | Confirmation (B2 / staging / channel) | Grounded in |
|---|---|---|---|
| X-1 | B2 does not touch S3 (registry/pivot identity) | B2 reads uncertified birth_registry rows; it never mints identity / writes S3 (B2-AC-3). Only B1 writes S3. |
interface §10; B2-AC-3 |
| X-2 | B2 does not touch S4 (canonical address) | B2 writes inspect_* only; never canonical_address/owner/jsonb_profile/status (B2-AC-2). Only B6 maps S4, at promote. |
interface §6/§10; B2-AC-2 |
| X-3 | B2 / staging / channel write no KG provenance | B2 writes only the three inspect_* columns; staging writes only candidate inspect_*; the channel only invokes the producer. None writes provenance/edges (B2-AC-4). |
modular §8; B2-AC-4 |
| X-4 | No KG backfill is designed | this bundle designs no edge-provenance backfill (that is K4, a separate R1 workstream). | §0 lock; modular §8 (K4) |
| X-5 | No quarantine lane is implemented | this bundle implements no "no-provenance ⇒ quarantine" lane (that is K5, absent today, a separate R1 workstream). | §0 lock; modular §8 (K5) |
| X-6 | No Qdrant-as-provenance logic | this bundle treats no embedding/vector result as provenance or as registry identity (K7 category guard). | modular §8 (K7); AC-8 |
| X-7 | No graph authority / KG runner work | this bundle does no KG runner work; the 5-gate KG preflight (K1) stays shut; no KG DOT is contracted/promoted. The agent-api executor, if later chosen as B2's channel, binds per-DOT so it does not couple the birth lane to the KG lane. | modular §8 (K1/K2); channel decision §7 |
| X-8 | Điều 39 provenance invariant not violated | the birth lane never writes edges/provenance, so it cannot violate "Edge PHẢI có provenance"; the invariant's enforcement (and the 2199/0-provenance backlog) is the separate R1 macro, not touched, not resolved here. | Phase-1B PH1-F1; §0 lock |
| X-9 | Birth lane independent of KG lane (AC-7) | identity (S3) is structural and precedes inference; B1/B2/B4 never depend on KG reasoning; the lanes converge only at S1 (Điều 32) for writes and S5/S6 for materialization — neither reached by this bundle. | modular §12; AC-7 |
Cross-check verdict: CLEAN. B2 / staging / channel touch none of S3/S4, the KG edge store, provenance, quarantine, Qdrant, or the KG runner; they introduce no KG backfill, no quarantine implementation, no Qdrant-provenance, no graph authority; and they violate no Điều 39 provenance invariant (the birth lane writes no edges). The shared-channel case (agent-api) is the only point of contact, and it is kept safe by per-DOT contracts (the channel decision's AC-7-preserving note). No R1/KG workstream is opened (R1_SCOPE_CREEP not triggered); the Điều 39 invariant is respected here and resolved nowhere here.
6. Owner-gated future work (R1-lane — referenced only, not opened)
Every R1 action below is forbidden now and belongs to the separate R1 macro, not this bundle. Listing is cross-check context, not authorization.
| Future R1 work (NOT opened here) | Gate required | Forbidden now? |
|---|---|---|
| Recover the provenance source-of-truth (K3 / S167H) | external S6 — Owner out-of-band | Yes |
Backfill edge provenance (K4) |
Điều 32 + S5 + K3 SoT | Yes |
| Build the quarantine lane (K5) | Điều 32 (+ design after K3) | Yes |
| Clear any KG gate / promote a KG contract (K1/K2) | Điều 32, in R1-D2 order | Yes |
| Enforce the Điều 39 provenance invariant | the separate R1 macro (Owner-gated) | Yes |
7. What remains unresolved
- The Điều 39 provenance invariant is unmet on the live edge store (2199 edges / 0 provenance; PH1-F1, HIGH) — this bundle respects it (writes no edges) but does not enforce or resolve it; that is the separate R1 macro.
- R1/KG is a cross-check only — no KG backfill / quarantine / Qdrant / runner work is opened (
R1_SCOPE_CREEPnot triggered). - The shared-channel coupling risk (agent-api serves both lanes) is guarded by per-DOT contracts — confirmed, not built.
- CAV-1/CAV-2 (R1-lane) carried — no executor process-log proof; "no provenance SoT" = substrate-scoped, not unrecoverable.
- Blockers — all OPEN, none resolved: CONS-002, CONS-003, CELL-003/004/007, HOLD-1, HOLD-2, RISK-BYPASS, GOV-016/017, GOV-REUSE-001, Điều 39 runtime-EMPTY, Điều 35 production-readiness FAIL.
- FUTURE_TECHNICAL_DESIGN_REQUIRED (NOT written here): all R1/KG mechanics (backfill, quarantine, recovery, runner).
8. Ready for GPT/Codex review
Yes — as a design-only invariant cross-check, not an R1 workstream.
Core rule, kept above all detail: the birth lane (B2/staging/channel) shares zero write surface with the KG lane; it touches no S3/S4, no edge provenance, no quarantine, no Qdrant, no KG runner; it violates no Điều 39 provenance invariant (it writes no edges). The cross-check is CLEAN; no R1/KG work is opened or resolved here.
Default disposition: HOLD. Engineering PASS = a complete cross-check on paper; it is not an Owner authorization to open any KG work. No PASS authorizes writes. All blockers remain OPEN.
