§2 — DDL Summary

schema: cutter_governance   (recommended; no reason to deviate — §6 of draft)
tables_created (DRAFT, empty):
  manifest_envelope:    12 columns; PK (envelope_id); 0 FK on itself
  manifest_unit_block:  14 columns; PK (envelope_id, unit_local_id);
                        1 FK: envelope_id -> manifest_envelope.envelope_id
foreign_keys_total: 1   (the ONLY PG FK in P0-2; in-schema; NO ACTION)
cross_schema_FK: 0
CHECK_constraints: 0
triggers: 0
DEFAULT_clauses: 0      (reconciled — see §4 / deviations)
alias_ref_column: ABSENT (GOV-3 O1)
edge_tables: 0
INSERT_statements: 0    (tables empty)
transaction: single BEGIN … COMMIT
idempotency: no IF NOT EXISTS (fail-fast; re-runnability via rollback) — explained
source_span_form: jsonb NOT NULL (DDL-authoring decision)
unit_local_id_type: text ; render_order_type: numeric

§3 — DDL ↔ GPT Decision Conformance

GPT-ratified item	DDL conforms?	Note
manifest_envelope field set / status lifecycle / soft refs	✅	12 cols per envelope design; lifecycle is app-layer enum (no CHECK)
manifest_unit_block composite PK + single in-schema FK	✅	PK (envelope_id, unit_local_id); FK envelope_id→envelope only
cross-schema refs soft uuid only	✅	target_unit_id, escalation_ref, cut_change_set_ref, decision_backlog_ref, superseded_by_envelope_id all soft, no PG FK
no CHECK / trigger / DEFAULT	✅	none authored (DEFAULT reconciliation §4)
no manifest↔alias coupling (GOV-3 O1)	✅	no alias_ref column anywhere
no edge tables	✅	edge intent carried in candidate_edges JSONB only
GOV-1 O3-hybrid	✅ (column)	proposed_canonical_address exists; tail/sequence coining = P1 logic, not PG
GOV-2 O1 demote-to-draft	✅ (column)	proposed_authority snapshot only; born-draft enforced app-layer/P1 (no PG DEFAULT)
tables empty at create; rollback = drop empty	✅	no INSERT; rollback draft drops child→parent
split/merge execution = P1	✅	no executor/state/trigger machinery authored

Conformance: full. No design field omitted or added.

§4 — Deviations

deviation_1:
  what: no PG DEFAULT clause, despite envelope/unit-block design field notes
        annotating envelope_id "gen_random_uuid() at DDL time" and created_at
        "now() at DDL time"
  classification: reconciled — deviation from design-doc ANNOTATION, NOT from
        binding constraints
  why: GPT review §3 (pg_CHECK_trigger_DEFAULT: avoid_in_P0_2) and both design
        docs (no_PG_..._DEFAULT_data_in_P0_2: TRUE) are authoritative and take
        precedence. Tables are empty with zero v0.2 writers, so a DEFAULT is
        inert until P1 INSERT. "Prefer none if consistent" was explicitly
        requested. Value-generation policy is deferred to the P1 writer layer.
  surfaced_for: GPT confirmation in this review
deviation_2:
  what: no IF NOT EXISTS / idempotency wrapper
  classification: deliberate posture, not an omission
  why: fail-fast on pre-existing object is correct for a gated governance
        migration; controlled re-runnability is provided by the rollback draft
        + single-transaction atomicity (draft §7)
other_deviations: NONE
concrete_choices_made_at_authoring (design left open, not deviations):
  - source_span = jsonb (avoids range/exclusion → no CHECK)
  - unit_local_id = text ; render_order = numeric
  - schema = cutter_governance

§5 — Blockers Before Dry-Run

- GPT review PASS of this 5-file DDL-authoring package
- explicit User authorization to enter a dry-run lane
- dry-run env provisioning authorization (protected dry-run envs must not be
  reused/torn down without explicit authorization)
status: dry-run NOT allowed at this gate (GPT review §6)
next_gated_step: GPT review of this package -> (if PASS) await explicit User
  prompt for a dry-run authorization in a SEPARATE session. Self-advance PROHIBITED.

§8 — Readiness

p0_2_ddl_authoring_status: ready_for_gpt_review
all_5_files_authored: TRUE
internally_consistent: TRUE
conforms_to_gpt_decisions: TRUE (1 reconciled annotation-level deviation, surfaced)
ddl_executed: FALSE
dry_run_started: FALSE
production_migration_allowed: FALSE
agent_self_advance: PROHIBITED
what_gpt_review_should_decide:
  - approve / revise the DDL draft (esp. the no-DEFAULT reconciliation,
    source_span=jsonb, no-IF-NOT-EXISTS posture, cutter_governance placement)
  - confirm the verification plan + stop criteria are sufficient
  - (only if PASS) authorize the NEXT gate: a dry-run lane via explicit User prompt
