dot-iu-cutter v0.1 — HB-09 Schema + Row-Count Snapshots + Dry-Run Environment Closure

Date: 2026-05-15 Status: HB-09 CLOSURE RECORD — closed_with_notes Trigger: GPT review of CTE-02/03/04 batch returned PASS; user explicitly authorized HB-08 + HB-09 operational infrastructure batch. Scope: SNAPSHOT + DRY-RUN ENV PROVISIONING ONLY. No P0 DDL, no cutter_governance schema, no P0 tables, no tac_logical_unit alteration, no business data mutation, no P0 migration executed, no rollback dry-run, no HB-05 execution, no deploy, no production mutation.

1. Schema Snapshot Artefact

schema_snapshot:
  path: /opt/incomex/backups/dieu44_hb09_2026-05-15/directus_schema_20260515T102438Z.sql
  format: pg_dump --schema-only (plain SQL, no data)
  size_bytes: 978,801
  size_human: 956 KB
  line_count: 29,559
  timestamp_utc: 2026-05-15T10:24:38Z
  pg_version_at_dump: PostgreSQL 16.13
  database_name: directus
  user: directus
  checksum_sha256: fd00ba64ecd2b579265799a7203faaced5a4e54fc5eb51e1f624c6a313ed3ef1
  checksum_file: /opt/incomex/backups/dieu44_hb09_2026-05-15/SHA256SUMS
  scope: all schemas (public + any extension schemas) — captures pre-migration absence of cutter_governance schema (which DOES NOT yet exist)
  intent_per_preflight_plan_§4:
    - serves as authoritative "before" state for diff-based rollback verification
    - rollback at execution time must reconcile post-rollback schema against this snapshot
  command_summary: ssh contabo 'docker exec postgres pg_dump -U directus -d directus --schema-only' (read-only)

2. Row-Count Snapshot Artefact

row_count_snapshot:
  path: /opt/incomex/backups/dieu44_hb09_2026-05-15/directus_rowcounts_20260515T102453Z.psv
  format: pipe-separated values (schema|relname|n_live_tup)
  size_bytes: 6,552
  size_human: 6.4 KB
  line_count: 245 (one row per user-visible table in public schema)
  timestamp_utc: 2026-05-15T10:24:53Z
  source_query: SELECT schemaname, relname, n_live_tup FROM pg_stat_user_tables ORDER BY schemaname, relname
  checksum_sha256: 114cf8a239d411e6bdb3c4b007497466100034177da2ada93aed799c461d2f44
  checksum_file: /opt/incomex/backups/dieu44_hb09_2026-05-15/SHA256SUMS
  scope: 245 user-visible tables in public schema (production scale at 2026-05-15T10:24:53Z)
  approximation_note: n_live_tup from pg_stat_user_tables is approximate; cross-verified at HB-08 restore test where restored counts matched production counts 10/10 on key tables
  intent_per_preflight_plan_§5:
    - post-migration row counts of unaffected tables compared against this snapshot — must be unchanged
    - new cutter_governance tables expected to have 0 production rows on first DDL
  sample_key_table_values_captured (subset; full list in artefact):
    - admin_fallback_log: 22
    - collection_registry: 166
    - dot_tools: 309 (post HB-07 registration of 991 + 992)
    - information_unit: 98
    - knowledge_documents: 2802
    - tac_logical_unit: 86
    - tac_publication: 3
    - tac_unit_version: 86
    - tasks: 10
    - universal_edges: 2199
  command_summary: ssh contabo 'docker exec postgres psql -U directus -d directus -tAF "|" -c "..."' (read-only)

  volume_name: pg-dry-run-hb05-2026-05-15-data
  image: postgres:16 (same major as production; PG 16.13)
  network: bridge (Docker default; NOT shared with production network)
  status: Up (provisioned at 2026-05-15T10:28Z)
  isolation_verified:
    - distinct container name (no collision with production `postgres`)
    - distinct volume name (no collision with production data volumes)
    - no port published on host (only reachable via `docker exec`)
    - bridge network — no shared production-network attachment
  baseline_restored:
    source_backup: /opt/incomex/backups/dieu44_hb08_2026-05-15/directus_full_20260515T102350Z.dump (HB-08 SHA-256 verified)
    restore_exit_code: 1 (one ignored warning: workflow_admin role missing; same as HB-08 restore test; non-fatal)
    smoke_test_table_count: 236 (matches HB-08 restore-test result)
    smoke_test_dot_pair_present: TRUE (id 991 + 992 active)
  intended_use:
    - HB-05 26-scenario rollback test plan dry-run will execute against this environment

    - cutter_governance schema + P0 tables will be CREATED in this dry-run env (not in production) for the 26 scenarios
  lifecycle:
    - persists until HB-05 closure completes
    - HB-05 closure session will instruct tear-down post-sign-off
    - alternatively: tear-down at any time via `docker stop && docker rm && docker volume rm`

7. Downstream Effects

downstream_effects_of_hb_09_closure:
  HB_05_rollback_test_plan_dry_run:
    status_before_this_closure: blocked (terminal node; awaiting HB-08 + HB-09)
    status_after_this_closure (paired with HB-08 closure in same batch): ready_to_close
    note: HB-05 now has all prerequisites closed_with_notes (HB-06, HB-03, HB-07, HB-09, HB-04, CTE-02, CTE-03, CTE-04 closed_with_notes; HB-08 closed_with_notes via sibling closure in this batch)
    next_action: open separate explicit-prompt session for Đ32 (HIGH-risk path) + G-4 to:
      1. transcribe CTE-03 canonicalization library scaffold + CTE-04 signing scheme scaffold from their closure records into the dry-run env (pg-dry-run-hb05-2026-05-15)
      2. execute the 26-scenario rollback test plan dry-run per HB-05
      3. record Đ32 + G-4 sign-off + closure file
  preflight_checklist_per_preflight_plan_§9:
    - schema_snapshot_recorded: closed_with_notes (this closure)
    - row_count_snapshot_recorded: closed_with_notes (this closure)
    - dry_run_environment_available: closed_with_notes (this closure; persistent for HB-05)

8. Status

HB_09_status: closed_with_notes
HB_09_closure_authority: operational DBA + G-2 Backlog Custodian (placeholder for v0.1 — G-2 = GPT per HB-06)

  - operational DBA placeholder (Đ37-assigned at execution time; v0.1 acknowledged)

dry_run_environment_baseline_restored: TRUE (from HB-08 backup; SHA-256 verified)
dry_run_environment_smoke_test: PASS (236 tables; HB-07 DOT-pair 991/992 present)
dry_run_environment_used_yet: NO (HB-05 is a separate session)

execution_authorized: false
implementation_allowed: false
ddl_allowed: false
p0_migration_allowed: false
p0_schema_created_in_dry_run: false (no P0 DDL run in dry-run env yet)
HB_05_unlocked: TRUE (paired with HB-08 closure in same batch)

notes_carried_forward:
  - dry-run env is persistent — HB-05 closure session uses it directly
  - HB-05 26-scenario tests will CREATE cutter_governance schema + P0 tables IN THE DRY-RUN ENV (not in production)
  - CTE-03 + CTE-04 scaffolds will be transcribed into the dry-run env at HB-05 prep time (engineering session; separate explicit prompt)
  - dry-run env can be torn down at any time; production-execution-bound snapshots will be separate execution-phase artefacts taken immediately before first DDL on production
  - the v0.1 snapshots captured here serve both as HB-05 reference baseline AND as the pattern for execution-phase snapshots

9. Hard Boundaries Confirmation

no_cutter_governance_schema_created: true (neither production nor dry-run)
