0. Status and non-authorization

STATUS: PASS — engineering / design-only. Confirms the 110 deliverables stay LEGO: each born/checked/replaced/rolled-back separately, assembled only through explicit IO contracts. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Hold the mandatory preamble: large at the orchestration layer, never at the coupling layer.

2. Sources / evidence read

Macro-4 LEGO boundary map (D3); Macro-4 no-mega-registry/graph/birth-pipeline locks; the Owner LEGO invariant carried since the block-contract packets. Main process, no reader-agents.

3. Accepted baseline (carried)

Isolated blocks; explicit contracts; born/tested/replaced/rolled-back separately; no mega-registry, no mega-graph, no mega-birth pipeline, no hidden coupling, no automatic promotion.

4. Evidence / analysis — separability check

LEGO property	How Macro-5 holds it
independently reviewable	each of the 110 files is one self-contained doc, one concern, 8 sections
independently replaceable	any file can be rewritten without editing its neighbours (pointer-linked only)
independently discardable	deleting any file removes exactly that concern; no shared mutable state
assembled via IO contracts	composition is by referencing another doc's output as input, never a shared store
B2 only primary	only B2 (inspect producer) is deepened; others are reference-only

5. Candidate / requirement / gate / result

B2 = only primary block. B5/B7 = dependency-only. R1/KG = cross-check-only (Điều 39 OPEN, untouched). No mega-registry / mega-graph / mega-birth pipeline. If any deliverable could not be independently reviewed, replaced, or discarded, the macro returns NOT_LEGO_COMPATIBLE → HOLD. Status this run: NOT triggered.

6. Owner-gated future work

Binding any block to runtime is Owner-gated; forbidden now.

7. What remains unresolved

Physical separability of a future built surface is a build-time proof (delete-fast/no-touch), not provable in a design package.

8. Ready for GPT/Codex review

Yes — Codex should attack any deliverable that hides coupling or cannot be discarded alone.
