Macro-3 Option-D LEGO Boundary Map — R2-B2 (2026-06-19)

Date: 2026-06-19 · Workstream: R2-B2-MACRO-3-OPTION-D-OWNER-DELEGATE-DECISION-PACKAGE-2026-06-19 (Deliverable 4 of 60) · Editorial revision: rev1 Class: LEGO boundary map · READ-ONLY · NON-ENACTING · NON-AUTHORIZING · NO write performed.

Metadata convention. Editorial revision (rev1) only. Storage revision/content_length authoritative at read time.

LEGO lock. Large at the orchestration layer only. Increase deliverable count, not system coupling. Every deliverable must be born / checked / replaced / rolled back separately, assembled only through explicit IO contracts. Any deliverable that cannot be independently reviewed, replaced, or discarded → NOT_LEGO_COMPATIBLE → HOLD.

0. Status and non-authorization

STATUS: PASS — engineering / decision-prep. Maps the 60 deliverables to independent LEGO blocks. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Show that the package is large only in count, not in coupling, and record the primary/dependency/cross-check block locks.

2. Sources / evidence read

Macro-2 no-mega-pipeline invariant check, B5/B7 + R1/KG scope locks; Owner LEGO invariant. Main process, no reader-agents.

3. Accepted baseline (carried)

Owner LEGO invariant: isolated blocks, explicit contracts, born-tested-replaced-rolled-back separately; no mega-registry / graph / birth-pipeline / hidden coupling / auto-fix-without-gate.

4. Evidence / analysis

The 60 deliverables fall into 7 groups (top layer, channel, S2, Điều 0-G, gate/Macro-4, locks, review/handoff). Each file is self-contained: it states its own status, sources, recommendation, and review-readiness, and can be discarded without breaking another (cross-references are pointers, not dependencies).

5. Recommendation / matrix / result

Block	Role	Lock
B2	only primary block = inspect producer	must not certify / canonicalize / mint identity / write KG prov / run backlog / flip gates / promote staging→prod / become mega-birth
B5 (backlog)	dependency only	not opened → else B5_B7_SCOPE_CREEP → HOLD
B7 (gate/GUC policy)	dependency only	not opened → else B5_B7_SCOPE_CREEP → HOLD
R1 / KG (Điều 39)	invariant cross-check only	not opened → else R1_SCOPE_CREEP → HOLD
Channel	internal of B2 (B2-AC-7)	replaceable; not authority

6. Owner-gated future work

Any future assembly of these blocks into a running producer is Owner-gated and out of scope here.

7. What remains unresolved

The blocks are designed-as-separable on paper; physical separability is proven only when Macro-4+ builds against explicit IO contracts.

8. Ready for GPT/Codex review

Yes — Codex should test each deliverable for independent reviewability/replaceability/discardability.
