0. Status and non-authorization

STATUS: PASS — engineering / design-only. The postflight rule: a staging surface may exist only if a build was Owner-authorized. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Tie the existence of any staging object to a prior Owner authorization.

2. Sources / evidence read

Macro-5 staging build non-execution lock (9); naming model (16); FRESH staging-table list. Main process, no reader-agents.

3. Accepted baseline (carried)

No staging object exists now; one may exist only after an Owner build-authorization, under the named isolation scheme.

4. Evidence / analysis — existence rule

State	Allowed?
no staging object (today)	yes — FRESH confirms only production iu_core.*/unit_edit_draft
a staging object after Owner SB-authorization	yes — under the named scheme, disposable
a staging object without authorization	no — STAGING_BUILD_DRIFT → HOLD

5. Candidate / requirement / gate / result

After a build, postflight PT-3 must confirm the staging surface (a) exists only because the Owner authorized it, and (b) is named per the disposable scheme. FRESH today: no macro5/b2draft object exists; the rule is satisfied by absence.

6. Owner-gated future work

Authorizing the build that creates the surface is an Owner act; forbidden now.

7. What remains unresolved

No staging object exists; the rule is currently satisfied by absence.

8. Ready for GPT/Codex review

Yes — Codex should confirm no staging object exists and existence is authorization-bound.
