phase: v0.2 — P0-6 + P0-5-remainder r2 DRY-RUN verification (executed on isolated env)
verification_executed: true (dry-run env only)
result: ALL REQUIRED PROOFS PASS

19	A-1 gate (decision_backlog_entry PK = entry_id uuid)	PF_A1_dbe_pk=entry_id uuid; A1_GATE=PASS	✅ PASS

§2 — FK Shapes (exactly 7; entry_id family confirmed)

review_decision_manifest_fk         review_decision             -> manifest_envelope
   FOREIGN KEY (manifest_id) REFERENCES manifest_envelope(envelope_id)
review_decision_unit_block_fk       review_decision             -> manifest_unit_block
   FOREIGN KEY (manifest_id, manifest_unit_local_id) REFERENCES manifest_unit_block(envelope_id, unit_local_id)
review_decision_prior_fk            review_decision             -> review_decision
   FOREIGN KEY (prior_review_decision_id) REFERENCES review_decision(review_decision_id)
review_decision_superseded_fk       review_decision             -> review_decision
   FOREIGN KEY (superseded_by_review_decision_id) REFERENCES review_decision(review_decision_id)
decision_backlog_history_entry_fk   decision_backlog_history    -> decision_backlog_entry
   FOREIGN KEY (entry_id) REFERENCES decision_backlog_entry(entry_id)            ← r2
decision_backlog_dependency_from_fk decision_backlog_dependency -> decision_backlog_entry
   FOREIGN KEY (from_entry_id) REFERENCES decision_backlog_entry(entry_id)       ← r2
decision_backlog_dependency_to_fk   decision_backlog_dependency -> decision_backlog_entry
   FOREIGN KEY (to_entry_id) REFERENCES decision_backlog_entry(entry_id)         ← r2

All 7 match the GPT-required list exactly. The 3 P0-5 FKs reference decision_backlog_entry(entry_id) (r2 A-1 fix) — confirmed.

§3 — Column Counts (match r2 DDL)

review_decision: 25            (V_colcount)
decision_backlog_history: 9    (incl entry_id; NO decision_id)
decision_backlog_dependency: 6 (incl from_entry_id,to_entry_id; NO *_decision_id)
decision_backlog_sweep_log: 10

§4 — Rollback Test

order: sweep_log → dependency → history → review_decision (child-safe; single txn)
output: BEGIN / DROP TABLE ×4 / COMMIT ; RB_RC=0
cutter_governance_after_rollback_count: 8
cutter_governance_after_rollback_list: canonical_address_alias, cut_change_set,
  cut_change_set_affected_row, decision_backlog_entry, dot_pair_signature,
  manifest_envelope, manifest_unit_block, verify_result
result: ✅ PASS — dry-run state returned to exact pre-batch state (8 tables);
  no live parent table dropped; production NOT rolled back (untouched)

§5 — Notes

N-1: 3 benign restore errors (role "context_pack_readonly" does not exist) —
  prod-only GRANT/RLS role absent in ephemeral env; ON_ERROR_STOP=0 on restore
  by design; ZERO impact on tested objects (all fidelity gates PASSED).
=> overall: PASS_WITH_NOTES (consistent with Phase α / P0-2 precedent).

§6 — Verdict

all_required_proofs: PASS (19/19)
rollback_test: PASS
dry_run_status: PASS_WITH_NOTES
production_migration_allowed: FALSE
output_form: p0_6_p0_5_remainder_r2_dry_run_verification_results

End of r2 dry-run verification results (ALL PASS).
