document_path: knowledge/dev/laws/dieu44-trien-khai/v0.2-dry-run/dot-iu-cutter-v0.2-phase-alpha-dry-run-execution-report-2026-05-15.md
revision: r1
date_authored: 2026-05-15 (package date convention)
executed_utc: 2026-05-16 ~01:48–02:05 UTC
author: Agent (Claude Code CLI, Opus 4.7 1M)
phase: v0.2 — Phase α DRY-RUN execution (dry-run env ONLY)
authorization: GPT PASS on r2 authoring + explicit dry-run-lane prompt (2026-05-15/16)
ddl_revision_used: r2 (r1 superseded; NOT executed)
dry_run_executed: TRUE
production_ddl_executed: FALSE
production_mutated: FALSE
production_migration_performed: FALSE
deploy_performed: FALSE
cut_verify_run: FALSE
phase_alpha_dry_run_status: PASS_WITH_NOTES
production_still_forbidden: TRUE

§1 — Scope & Authorization

GPT verdict: phase_alpha_ddl_authoring_r2_status = PASS, agent_revision_needed = false, dry-run lane opened, production migration remains forbidden. This session executed Phase α DRY-RUN ONLY against a fresh isolated sibling environment. No production DDL/mutation/migration/deploy/CUT-VERIFY; no self-advance to production command review.

§2 — Dry-Run Environment

dry_run_env_name:        pg-dry-run-v0.2-phase-alpha-2026-05-16
image:                   postgres:16  (server reported PostgreSQL 16.13 — matches production)
isolation:               docker bridge; NO published host port
                         HostConfig.PortBindings = {}  ; NetworkSettings.Ports = {"5432/tcp":null}
volume:                  pg-dry-run-v0.2-phase-alpha-2026-05-16-data
sibling_of:              v0.1 HB-05 env — NOT reused
hb05_env_reused:         FALSE  (pg-dry-run-hb05-2026-05-15 left untouched, still Up)
db / superuser:          directus / workflow_admin  (server=local-unix socket)
production_container:    'postgres' — DIFFERENT container, never targeted

Every script enforced identity guards that abort if the target var is empty, not exactly pg-dry-run-v0.2-phase-alpha-2026-05-16, equal to the production container name, or if a host port is published.

§3 — Baseline Backup & Restore

backup_method:           fresh pg_dump -F c -Z 6 from PRODUCTION 'postgres' container (read-only; production NOT mutated)
backup_role:             workflow_admin (owns cutter_governance + sandbox_tac; rolsuper=t)
backup_path:             /opt/incomex/backups/dieu44_phase_alpha_2026-05-16/phase_alpha_baseline_20260516T014848Z.dump
backup_sha256:           455fea54bfee615c7ac351bf6546cae23cbaa88aeb54191eb820a1a9b20d6bec
backup_size_bytes:       64,572,242
backup_taken_utc:        2026-05-16T01:48:48Z
roles_captured:          schema/roles_dump.sql (context_pack_readonly, directus, incomex, workflow_admin)
restore_target:          dry-run env ONLY (fresh empty 'directus' DB created, then pg_restore --no-owner --role=workflow_admin)
restore_result:          PASS — pg_restore 0 errors (only benign "role workflow_admin already exists" from roles step)
post_restore_verify:     tac_logical_unit=86 ; sandbox_tac.logical_unit=76 ; cutter_governance=5 v0.1 tables ; canonical_address_alias absent

Production was current and matched the 2026-05-15 baseline (tac=86, sbx=76, 5 empty cg tables, max(updated_at)=2026-04-30) — a strictly fresh backup was nonetheless taken to satisfy the "fresh/current production backup" requirement.

§4 — Extracted Executable SQL (frozen r2)

source_doc:              knowledge/.../v0.2-ddl-authoring/dot-iu-cutter-v0.2-phase-alpha-ddl-draft-2026-05-15.sql.md (revision 2 confirmed)
extracted_body:          §2 single-transaction SQL only (BEGIN; … COMMIT;)
artefact_path:           /opt/incomex/backups/dieu44_phase_alpha_2026-05-16/sql/dot-iu-cutter-v0.2-phase-alpha-r2.sql
artefact_sha256:         65533e0564ee45625b43bff383252ec03f20e284a5cc506d78e1079d6f893fe3
lines:                   175 ; BEGIN count=1 ; COMMIT count=1
r1_executed:             FALSE (r1 superseded, never extracted/executed)

§5 — Preflight (dry-run env)

db_identity:             db=directus user=workflow_admin server=local-unix  (isolated)
baseline:                tac=86 ; sbx=76 ; cutter_governance = {cut_change_set, cut_change_set_affected_row, decision_backlog_entry, dot_pair_signature, verify_result} ; canonical_address_alias ABSENT ; Phase α columns ABSENT
pre_backfill_sanity:     Q-CHK-1 = 0 (section_type vocab all active)
                         Q-CHK-2 = 0 (parent_id resolution + doc_code parity clean)
                         Q-CHK-3 = 0 (canonical_address regex all pass)
pre_DDL_updated_at:      86 rows; min 2026-04-29 05:27:37.951703+00; max 2026-04-30 03:12:19.569465+00; 3 distinct
pre_DDL_schema_snapshot: schema/predll_schema_dryrun_20260516T020054Z.sql (26031 lines; sha256 42441c5d…9156b)
production_untouched:    confirmed (86|76|5|0, newcols=0, max_updated_at 2026-04-30)

§6 — DDL Execution (dry-run ONLY)

command:                 psql -U workflow_admin -d directus -v ON_ERROR_STOP=1 -f r2_phase_alpha.sql  (in dry-run container)
transaction:             single in-file BEGIN … COMMIT (atomic)
psql_exit_code:          0
echoed_steps:            ALTER TABLE ×.. , COMMENT ×.. , CREATE TABLE , CREATE INDEX ×4 , COMMIT
in_transaction_trailing_SELECT (exactly the GPT r2 expectation):
  tac_authority_draft=86  tac_authority_enacted=0  tac_authority_runtime=0  tac_authority_null=0
  tac_format_v1=86        sandbox_authority_null=76 sandbox_format_v1=76     alias_table_present=1
exec_output_artefact:    logs/04_ddl_exec_output_20260516T020437Z.txt

§7 — Verification Summary

All 16 verification-plan checks + cutter_governance row-total + tac integrity + V-α-16 schema-diff: PASS (16/16). Detail in the companion verification-results KB doc and logs/04_verification_results_20260516T020437Z.txt.

V-a-1  public new cols     PASS  authority:text:YES:'draft'::text ; canonical_address_format_version:text:NO:'canonical-address-v1'::text
V-a-2  sandbox mirror cols PASS  (identical shape)
V-a-3  alias table exists  PASS  1
V-a-4  alias 9 cols order  PASS
V-a-5  alias 5 indexes     PASS  pkey + idx_alias_alias_kind/alias_text/target_unit_id/validity_window
V-a-6  public authority    PASS  draft=86 (no enacted/runtime/NULL)
V-a-7  public format_ver   PASS  canonical-address-v1=86
V-a-8  sandbox authority   PASS  NULL=76 (no 'draft' — r2 add-without-default proven)
V-a-9  sandbox format_ver  PASS  canonical-address-v1=76
V-a-10 alias rows = 0      PASS
V-a-11 canonical_address   PASS  text:NO:NULL (unchanged)
V-a-12 UNIQUE constraint   PASS  UNIQUE (canonical_address)
V-a-13 cg 6 tables         PASS  5 v0.1 + canonical_address_alias
V-a-13 cg total rows = 0   PASS
V-a-14 tac integrity       PASS  86:86:86 (rows:non-null:distinct)
V-a-15 sandbox rowcount    PASS  76
V-a-16 schema diff         PASS  removed=0 ; added=6 (alias table + PK + 4 indexes; new columns inline-rendered, confirmed by V-a-1/2)

§8 — updated_at Bump Measurement (Step 3 backfill side effect)

rows_changed:            86 / 86  (Step 3 UPDATE … WHERE authority IS NULL matched all 86, as the r2 add-without-default design intends)
pre_DDL_distinct_updated_at:  3
post_DDL_distinct_updated_at: 1
post_DDL_updated_at value:    2026-05-16 02:04:38.444072+00 (uniform — trg_tac_birth_gate_lu set NEW.updated_at := now())
assessment:              EXPECTED & ACCEPTED — documented in DDL draft r2 §4 and verification plan; normal UPDATE semantics. This is the primary positive evidence that the BR-4 backfill actually executed (the r1 defect would have left it un-run).
artefacts:               schema/exec_pre_updated_at_20260516T020437Z.csv ; schema/exec_post_updated_at_20260516T020437Z.csv

§9 — Rollback Test (in-transaction ROLLBACK — dry-run plan S26 / R-4)

method:                  frozen r2 body with final COMMIT replaced by ROLLBACK (ROLLBACK-variant artefact; begin=1 commit=0 rollback=1)
psql_exit_code:          0 (all DDL ran cleanly inside the transaction, then ROLLBACK)
post_rollback_state:     tac=86 ; sbx=76 ; tac_newcols=0 ; alias=0  (pristine)
schema_DDL_line_diff:    EMPTY (pre-DDL snapshot vs post-rollback snapshot — full revert)
full_file_comparison:    DIFFERS only by pg_dump per-invocation \restrict/\unrestrict random nonce (4 lines; identical 26031/26031 line counts) — pg_dump invocation noise, NOT a schema delta
verdict:                 ROLLBACK_TEST_PASS — strongest rollback evidence; atomic abort fully reverts Phase α

Executed on the pristine baseline BEFORE the committing run, so no second restore was required.

§10 — Production Untouched Confirmation

production_container 'postgres' probed read-only BEFORE and AFTER all dry-run steps:
  tac=86 ; sbx=76 ; cutter_governance=5 ; canonical_address_alias=0 ; tac_newcols=0 ; max(updated_at)=2026-04-30 03:12:19.569465+00
UNCHANGED end-to-end. No DDL, DML, restore, or migration was dispatched to production.
pg-dry-run-hb05-2026-05-15 (v0.1 env): untouched, still Up.

phase_alpha_dry_run_status: PASS_WITH_NOTES
notes:
  N-1 updated_at bumped on all 86 rows by Step 3 backfill — expected/accepted (documented side effect)
  N-2 rollback full-file comparison shows pg_dump \restrict nonce noise only — not a schema delta
  N-3 V-a-16 ALTER-line grep shows 6 additions; the 2 new columns are inline-rendered by pg_dump and independently confirmed PASS by V-a-1 / V-a-2
production_status: FORBIDDEN (unchanged) — dry-run PASS does NOT authorize production

next_recommended_step (per dry-run plan §11; each step gated on GPT review / explicit prompt):
  1. GPT review of this dry-run execution report + verification-results + artefact-index
  2. Phase α HB-equivalent closure document
  3. GPT review of closure
  4. Phase α final readiness review → GPT review
  5. Phase α production command-review package → GPT review
  6. explicit User production execution prompt (separate session)
agent_self_advance_to_production_command_review: PROHIBITED
