0. Status and non-authorization

STATUS: PASS — engineering / design-only. The conditional branch plan for Macro-5; proposed, not launched. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Answer macro question 10 — what should Macro-5 do next? — as a conditional branch map after GPT/Codex review and Owner decisions.

2. Sources / evidence read

Macro-3 Macro-4 branch plan (B-A); staging-build vs actual-TD separation (59); entry gate v2 (55). Main process, no reader-agents.

3. Accepted baseline (carried)

Macro-5 may only be proposed; if Macro-4 passes GPT/Codex, Macro-5 = staging build authorization package or actual B2 TD gate package, still Owner-gated; no automatic launch.

4. Evidence / analysis — branch map

Branch	Condition	Macro-5 next action
M5-A staging build	Macro-4 accepted + Owner authorizes a staging build (SB gate Go)	prepare the staging build authorization package (still design→build-gated)
M5-B actual-TD prep	the three Owner decisions made (channel + S2 + Điều 0-G)	prepare the actual B2 TD entry package (design-only) once G-1…G-11 trend to Go
M5-C partial	some decided, some HOLD	prepare only the decided lane; keep others HOLD
M5-D hold	Owner keeps HOLD	re-verify read-only evidence; no new design surface
M5-E reject creep	request for B5/B7/R1 work	refuse → scope-creep guard

5. Contract / requirement / matrix / result

Recommended trigger: M5-A (staging build) is the smallest next step if the Owner wants forward motion, since the staging surface is the binding G-6 precondition for actual TD. No branch is launched here; all defaults HOLD.

6. Owner-gated future work

Launching any Macro-5 branch is Owner-gated; forbidden now.

7. What remains unresolved

Macro-5 not launched; trigger conditions unmet (no decisions, no build authorization).

8. Ready for GPT/Codex review

Yes — Codex should confirm even M5-A/M5-B stop at design/authorization, not implementation.
