Delivery016 exact inaccessible extension view guard correction

Local source403097fd9e373463c62022c18c7b7a2f841a0b16 corrects015's catalog false positive. Runtime reservation and future custody preflight share one SQL predicate. The only exception is the two exact inaccessible PUBLIC SELECT statistics views, with relation kind/name/namespace, extension1.11 membership, canonical owner, PUBLIC grant provenance and effective SELECT-only/noUSAGE/noCREATE checks. Unrelated inaccessible business/view privileges, namespace access, DML/MAINTAIN, ownership, membership and identity mismatches remain denied.

Twenty-five actual PostgreSQL cases exercise both guards,39 wrapper/caller tests and typecheck pass. Read-only production provenance confirms both exact view matches and zero residual relation privilege matches for the retired role. That owner catalog evaluation does not reopen the role or prove a new runtime login. Source/native physical packet and isolation checks are returned separately for root review.

Stopped015 commit250612cffd53945ec4f4333f2416faf27cd30111 contains complete provisioning/failure/cleanup evidence and its publication-ready owner memo. Delivery_phasec014/OID13363468 remains closed with passwordNULL/zero sessions. No015 environment rows or deployment were created. Proposal016 names fresh delivery_phasec016, preserving the original unactivated window/request with null dates/signature. No new production mutation, credential/key generation, staging or issuance occurred in016.

Accepted014 source/archive,013 artifacts, G2 and previous009/011 outcomes are preserved. Root remains sole canonical publisher. This correction and local native proof require source/artifact review and separate bounded staging authority before any production use.
