Class: no-mega-pipeline invariant check · READ-ONLY · NON-ENACTING · NON-AUTHORIZING · NO write performed.
Metadata convention. Editorial revision (rev1) only. AgentData storage revision/
content_lengthauthoritative at read time; not pinned here.
Invariant lock. Confirms B2 stays inspect-only, no mega-birth pipeline, no hidden shared write surface.
MEGA_BIRTH/B2_OVERREACH→ HOLD.
0. Status and non-authorization
STATUS: PASS — engineering / control. Confirms the no-mega-pipeline invariant holds across Macro-2's 45 deliverables. Nothing built or fused.
Engineering PASS ≠ authority PASS. Default disposition: HOLD. No mega-pipeline; no shared write surface; no DB write/DDL/DML; no TD; no blocker resolved; v0.1 not overwritten; v0.2 not authority.
Evidence basis — design synthesis + FRESH (RQ-1). Reading discipline: main process, no reader-agents.
1. Purpose
Confirm Macro-2 introduced no mega-birth pipeline, no mega-registry, and no hidden shared write surface — the LEGO invariant that binds all design.
2. Sources / evidence read
The inspect-producer TD-prep (B2-AC-12; §12 fused-shortcut rejection); the interface anti-coupling; the macro MANDATORY PREAMBLE (LEGO); Deliverables 25–34. Read directly, main process.
3. Accepted baseline (carried)
B2 = inspect-only; it must never certify/canonicalize/mint identity/write KG, never fake inspection, never use the 2026-03-21 fused INSERT, never become a mega-birth pipeline; each deliverable a separate control surface.
4. No-mega-pipeline checks
| # | Invariant | Held in Macro-2? | Evidence |
|---|---|---|---|
| MP-1 | B2 stays inspect-only (writes inspect_* only) | Yes | RQ-1 (B2 writes no canonical/identity/KG); reaffirmed in every B2 deliverable |
| MP-2 | No fused B1+B2+B3+B4 statement | Yes | fused shortcut rejected (Deliverable 25–29; C6 §12) |
| MP-3 | No mega-registry / second SSOT | Yes | no registry/schema/corpus created |
| MP-4 | No hidden shared write surface | Yes | B2 writes only B3 inspect_*, appends S7, routes via S1/Điều 32 |
| MP-5 | Channel stays a replaceable internal | Yes | Deliverables 6–12 (recommendation-only, no selection) |
| MP-6 | Each deliverable independently reviewable/replaceable/discardable | Yes | 45 separate control surfaces (Deliverable 45 matrix) |
| MP-7 | No automatic planning→TD→impl transition | Yes | every step Owner-gated; default HOLD |
Reading. Macro-2 is large at the orchestration layer (45 deliverables) but added no coupling: B2 stays inspect-only, no fusion, no second SSOT, no hidden convergence. MEGA_BIRTH / B2_OVERREACH not triggered; not NOT_LEGO_COMPATIBLE.
5. Result
The no-mega-pipeline / LEGO invariant holds across all 45 deliverables. OWNER_DECISION_REQUIRED at every future step (no automatic transition).
6. Owner-gated future work
Any producer build must honor MP-1…MP-7 under Điều 32; forbidden now.
7. What remains unresolved
- Invariant holds; nothing built.
- Blockers — all OPEN.
8. Ready for GPT/Codex review
Yes — as the no-mega-pipeline invariant check.
Core rule: B2 inspect-only; no fusion / no mega-registry / no hidden write surface; 45 separate control surfaces; MEGA_BIRTH/B2_OVERREACH not triggered; LEGO-compatible.
Default disposition: HOLD. Engineering PASS ≠ authority PASS. All blockers remain OPEN.
