123 — Phase 1 Rollback Readiness & Residue Check

Status: nothing to roll back — zero residue. No COMMIT, no open transaction, no temporary object, no session left behind.

123.1 Residue check (this session)

• Open transactions against directus: 0 (idle in transaction = 0).
• Temporary/partial objects: none — no DDL was issued; all six SB target relations remain ABSENT.
• Approval/intake rows: none created (os_proposal_approvals = 0).
• Leftover sessions: none — the read channel (query_pg) auto-closes its READ ONLY transaction per call.

123.2 Rollback readiness (for the future authorized build)

Per doc 89 §89.5 and doc 97, the future build remains pre-staged with:

• Per-step pg_dump of touched reuse tables (apr_action_types, governance_relations, governance_registry, dot_tools, dot_domains, dot_coverage_required, event_type_registry) immediately before each COMMIT.
• Documented rollback SQL: retire-not-delete for apr_action_types rows (and KEEP the F-83-1 trigger fix — never roll the trigger back into the broken argless state); DROP for greenfield SB tables; DELETE-by-event_domain for SB-11 event rows.
• Mandatory entry==exit BEGIN…ROLLBACK rehearsal before any COMMIT version (doc 91 template).

These artifacts were not needed this run because no build executed. They remain valid for the next run once M-1 is satisfied by a real sovereign e-signature.

123.3 Verdict

Rollback readiness: documented and intact. Residue: ZERO.
