0. Status and non-authorization

STATUS: PASS — engineering / design-only. The open questions for the Owner/GPT/Codex; answers none. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

List what is genuinely undecided after Macro-5.

2. Sources / evidence read

Macro-4 open-question register (D-lineage); entry gate v2 (D55); staging build gate (D57). Main process, no reader-agents.

3. Accepted baseline (carried)

Open questions are surfaced, not answered, in a design package.

4. Evidence / analysis — open questions (OQ)

#	Open question	Owner of the answer
OQ-1	which channel (host-cron / agent-api / other)?	Owner (R2-D2), GATE-4
OQ-2	who is the S2 B2 Producer Owner?	Owner, GATE-5
OQ-3	recover Điều 0-G source, or accept as basis?	Owner, GATE-3
OQ-4	which isolation scheme (schema / DB / tagged)?	Owner, SB-4
OQ-5	STAMP/GATE logic (least-precedented)	future TD
OQ-6	downstream-certify unwind (HOLD-2)	future TD
OQ-7	observed-role scope (BAD_INPUT_BEHAVIOR_UNCLEAR)	future TD
OQ-8	who halts the producer if the single owner is unavailable?	Owner

5. Candidate / requirement / gate / result

All eight remain open; Macro-5 answers none. OQ-1/2/3/4 are the binding preconditions for any build; OQ-5/6/7 are future-TD design questions.

6. Owner-gated future work

Answering OQ-1…OQ-4 is a set of Owner acts; OQ-5…OQ-7 are future TD; forbidden now.

7. What remains unresolved

All open questions.

8. Ready for GPT/Codex review

Yes — Codex should confirm none is pre-answered.
