0. Status and non-authorization

STATUS: PASS — engineering / decision-prep. Lays out the owner-model option space behind D16. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Give the Owner the model alternatives so the D16 recommendation is a choice, not a default.

2. Sources / evidence read

Macro-2 S2 candidate matrix, assignment readiness; Điều 32. Main process, no reader-agents.

3. Accepted baseline (carried)

Whatever model is chosen, it must satisfy accountability + halt-authority + no-self-approve.

4. Evidence / analysis — option matrix

Model	Accountability	Speed	Risk
M-1 single accountable owner role	clear (one role answerable)	fast	single point if unfit
M-2 committee / council	diffuse	slow	accountability dilution
M-3 hybrid: single owner + Điều-32 council review	clear + checked	medium	needs both roles staffed

5. Recommendation / matrix / result

Recommend M-3 (a single accountable owner role with Điều-32 reviewer/quorum) — equivalently, M-1 owner constrained by M-2 review. This keeps one answerable role + halt authority while preventing self-approval. No model is enacted; nobody assigned.

6. Owner-gated future work

Choosing M-1/M-2/M-3 and naming the role-holder are Owner acts; forbidden now.

7. What remains unresolved

Model not chosen; owner not assigned.

8. Ready for GPT/Codex review

Yes — Codex should test M-3 against the Điều-32 quorum rules for a deadlock or self-approval loophole.
