08 — Rollback & Artifact Inventory (Objective H, part 1)

Mutation ledger for this run

Surface	Writes performed	Persistent?
PostgreSQL directus	1 × BEGIN..ROLLBACK rehearsal (doc 02)	No — rolled back, entry==exit on both channels
PostgreSQL — COMMIT	none	—
system_issues / event_outbox	none	—
Directus / Qdrant / Nuxt	none	—
Local FS (knowledge/…)	package docs + SQL artifacts	yes (reports only)
KB (Incomex_KB)	package upload (doc 10)	yes (reports only)

Net governed-state delta = 0. Only residue is a non-transactional governance_object_ownership_id_seq advance (no row behind it) — cosmetic, standard for rolled-back inserts.

Rollback posture

• The rehearsal script (sql/f6_large_ownership_rollback.sql) ends in ROLLBACK; unconditionally; even on mid-script error the surrounding transaction aborts ⇒ rollback either way.
• For the future ratified COMMIT, the pre-staged reversal is DELETE FROM governance_object_ownership WHERE created_by LIKE 'F6_%'; — proven reversible (table has 0 triggers, no cascade).
