0. Status and non-authorization

STATUS: PASS — engineering / design-only. The tight inner loop: draft → adjust → delete-fast, with production untouched at every step. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Describe the fast-iteration loop inside a single draft, complementing the broader test-and-discard model (87).

2. Sources / evidence read

Draft object replace/delete contracts (16/17); delete-fast master + unit (37/38); rollback-without-production-touch (41). Main process, no reader-agents.

3. Accepted baseline (carried)

Adjusting a draft = (delete the old disposable unit) + (born a new one) against the same IO contract; in the workbench, deletion is the rollback.

4. Evidence / analysis — the loop

Step	Action	Property
draft	born a candidate (run id)	run-scoped, enumerable
run	exercise against fixture	fail-closed; candidate-only
inspect	read candidate inspect_* + evidence	records-not-decides
adjust	change the internal (channel/logic), keep the contract	contract-invariant (B2-AC-7)
delete-fast	dispose the run's unit (total)	no production residue (DFW/DFM)
repeat	born the next candidate	no cascade

5. Contract / requirement / matrix / result

The loop is bounded by the run id and the IO contract: adjustments touch only the internal; deletes are total; production is never written. It is a model; no loop is executed (producer/surface absent).

6. Owner-gated future work

Running the loop requires a built producer + staging — Owner-gated; forbidden now.

7. What remains unresolved

Conceptual only; no draft created/adjusted/deleted.

8. Ready for GPT/Codex review

Yes — Codex should confirm adjust touches only the internal and delete-fast leaves no production residue.
