0. Status and non-authorization

STATUS: PASS — engineering / design-only. The preflight check on GATE-4 (channel) — selecting nothing. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Confirm a build cannot proceed while the channel is undecided, without selecting one.

2. Sources / evidence read

Macro-4 channel assumption carried-not-authorized (D61); entry gate v2 G-4 (No-Go); FRESH 2026-06-19 channel evidence. Main process, no reader-agents.

3. Accepted baseline (carried)

GATE-4 (channel) is open and non-waivable; host-cron and agent-api are candidates, neither selected; pg_cron/queue are risky/future-gated.

4. Evidence / analysis — channel check (FRESH)

Candidate	FRESH status
pg_cron	absent (not installed)
host-cron (wf_host_crontab_snapshot)	54 jobs / 0 birth
agent-api (dot_agent_api_contract)	2 contracts / 0 birth-bound; :8090 healthy
queue worker	OFF / idle
Selected?	no — GATE-4 OPEN

5. Candidate / requirement / gate / result

No channel is selected; selecting one as runtime authority = CHANNEL_AUTHORITY_DRIFT → HOLD. Status this run: NOT triggered. The build preflight fails at PF-6 until the Owner selects + proves a channel.

6. Owner-gated future work

Selecting + wiring a channel is an Owner act (R2-D2); forbidden now.

7. What remains unresolved

GATE-4 OPEN; no channel chosen.

8. Ready for GPT/Codex review

Yes — Codex should confirm channels remain candidates, none selected.
