Verdict

ws_q5_registry_substrate_isolated_dryrun: PASS
agent_behavior: PASS_CORRECT
opus_review: CORRECT_ON_PASS_STATUS
ad4_correction: PASS
isolated_environment: PASS
catalog_verification: PASS
rollback_verification: PASS
production_authorized: false

Agent completed the AD-4 correction and isolated dry-run correctly. The dry-run environment was not production, catalog-level verification passed, and rollback left a clean post-state.

Production route ruling

GPT chooses a modified Option C.

production_route: OPTION_C_HYBRID_WITH_SEPARATE_PRODUCTION_COMMAND_REVIEW

Meaning:

step_1: VPS production read-only preflight / name-collision check
step_2: strip dry-run scaffold from production artifact
step_3: prepare production command package with exact SQL, rollback, verification commands
step_4: route to GPT/User sovereign production approval
step_5: only after approval, execute production apply in its own phase

This is not direct production apply. The hybrid route is chosen because it gives most of the safety benefit of a restored-prod-schema dry-run for this additive table-only DDL, while avoiding the overhead of a full pg_dump/restore cycle.

If VPS read-only access is unavailable, the phase must report BLOCKED and must not substitute production execution.

---

Why not Option B direct apply now

option_B_direct_apply: rejected_for_now
reason:
  - dry-run was isolated but not restored from production schema
  - production artifact still requires scaffold stripping
  - production command package must explicitly list exact SQL, transaction boundary, rollback, and verification commands
  - sovereign approval must be separate from dry-run review

Why not mandatory Option A full restored-prod dry-run

option_A_full_restored_prod_dryrun: not_required_now
reason:
  - DDL is additive, table-only, no ALTER on existing tables
  - plain CREATE TABLE will fail loud on collision
  - design-delta already found table names disjoint from existing known tables
  - read-only production catalog preflight is sufficient before a separate sovereign apply decision

If read-only preflight detects unexpected existing objects or schema drift, escalate to restored-prod-schema dry-run or stop.

---

Required next phase

Open a production preflight + command package phase:

next_phase: v0_5_WS_Q5_registry_substrate_production_preflight_and_command_package
nature: read_only_preflight_plus_command_package__no_apply

Allowed actions:

allowed:
  - read-only production catalog queries on VPS
  - verify cutter_governance schema exists
  - verify existing table names and 0 collision with 12 new tables
  - prepare production SQL artifact without dry-run scaffold line
  - prepare transaction-wrapped apply command package
  - prepare rollback command package
  - prepare production verification command package
  - produce sovereign approval prompt

Forbidden:

forbidden:
  - executing DDL in production
  - BEGIN/COMMIT production apply
  - creating tables
  - production writes
  - DML seed
  - GRANT/role changes
  - evidenced_by vocab amend
  - Cap-4 checker change
  - index execution
  - Directus mutation
  - CUT/VERIFY
  - deploy/restart
  - git commit
  - self-advance to apply
