Verdict

APPROVED FOR AGENT DISPATCH.

rev2 was close, but GPT patched it to rev3 before approval to eliminate remaining production-DDL risks.

Rev3 safety fixes

• Schema-qualified all target tables as public.*.
• Fixed trigger gate logic using explicit trigger names and correct boolean conditions.
• Added existing-column type/nullability/default STOP gate.
• Added explicit prohibition on vector columns.
• Added transaction-wrapped DDL with lock_timeout and statement_timeout.
• Added no-default/no-FK/no-index/no-trigger checks.
• Added row-count unchanged checks.
• Added existing rows new-column-null checks.
• Added function reachability check with fn_iu_create_plan only.
• Added rollback with transaction and lock timeout.

Scope approved

Only add these nullable/no-default columns:

public.information_unit:

doc_code TEXT NULL
section_type TEXT NULL
section_code TEXT NULL

public.unit_version:

title TEXT NULL
description TEXT NULL
review_state TEXT NULL
provenance TEXT NULL
editor TEXT NULL
enacted_at TIMESTAMPTZ NULL
updated_at TIMESTAMPTZ NULL

Still deferred

• vector sync columns;
• vocab FK/index/trigger;
• Directus refresh;
• TAC migration;
• publication view/compatibility layer;
• IU vector implementation;
• hash-rule enforcement.
