0. Status and non-authorization

STATUS: PASS — engineering / design-only. Carries Macro-3's channel recommendation as a planning assumption only; selects nothing. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Record the carried channel assumption and reaffirm no channel is runtime authority.

2. Sources / evidence read

Macro-3 channel final recommendation; FRESH channel substrate (list_docker, query_pg); inspect-producer §11 (channel matrix). Main process, no reader-agents.

3. Accepted baseline (carried)

Macro-3: prefer agent-api for governance traceability/observability/contract-bound promotion; keep host cron as fallback (lowest blast radius/faster pilot); no channel selected as runtime authority. The channel is an internal of B2 (B2-AC-7), replaceable.

4. Evidence / analysis (FRESH 2026-06-19)

Candidate	FRESH state
host cron	wf_host_crontab_snapshot=54, 0 birth; unwired; lowest blast radius
agent-api executor	Up healthy :8090; dot_agent_api_contract=2 (DOT_KG_EXPLAIN DRY_RUN + VERIFY; no_mutation_assertion=true), 0 birth-bound; switches OFF
pg_cron	absent (not installed) → risky/future-gated
job_queue worker	queue.worker.enabled=false, queue.job_substrate.enabled=false; idle → risky/future-gated
manual one-shot	reject as standing channel (that is B5)

5. Contract / requirement / matrix / result

The channel is carried as a planning assumption for workbench/IO-contract design (a channel id appears in the evidence contract). No channel is selected, wired, bound, installed, or enabled. Any wording that reads as selection is CHANNEL_AUTHORITY_DRIFT → HOLD. Status: NOT triggered. GATE-4 OPEN, non-waivable.

6. Owner-gated future work

Selecting/wiring the channel (host cron) or binding/promoting the agent-api contract is an Owner act; forbidden now.

7. What remains unresolved

Channel not selected; GATE-4 OPEN.

8. Ready for GPT/Codex review

Yes — Codex should confirm the channel stays a carried assumption, not a selection.
