111 — Phase 1 Rollback Readiness & Residue Check

Mutation footprint: ZERO. No COMMIT, no open transaction, no temporary objects. Read-only throughout.

111.1 Residue check (live, read-only, 2026-06-01)

• No author-mode write session was ever opened. Verification used only the read-only query_pg channel (READ ONLY txn, auto-closed).
• pg_stat_activity idle in transaction for directus = 0 — no stuck/dangling session.
• All six Phase-1 target tables ABSENT — no half-created DDL.
• All governance-scoped counts (relations 8, etr-gov 0, outbox-gov 0, apr_action_types 6, birth-apr 0, approvals 211/42, dot 309/46/11, law 47/5) identical to baseline — no DML residue.
• No pg_dump taken (none needed — no reuse table was touched).

Residue verdict: ZERO. The database is byte-for-byte at the pre-mission baseline.

111.2 Rollback readiness (for a future AUTHORIZED build)

Rollback assets remain staged and valid (no build consumed them):

• Per-step rollback runbook: doc 97 (retire-not-delete posture for SB-1; KEEP the F-83-1 fix on rollback).
• SQL-pack spec (default-ROLLBACK, NO-EXEC): doc 99.
• Reuse-table dumps required before an authorized COMMIT (doc 96 §96.4): SB-12→evolution_snapshots, SB-13→queue_heartbeat, SB-11→event_type_registry, SB-1→apr_action_types. Greenfield tables roll back by DROP.
• Disaster recovery: doc 97 §rollback/disaster.

Because nothing was committed, rollback readiness is intact and untouched — the next authorized build inherits the full, unused safety net.

Rollback-readiness verdict: PROVEN (staged, validated, unconsumed). Residue: NONE.
