3. Restore Test Target Environment

restore_test_environment:
  container_name: pg-restore-test-hb08-2026-05-15 (now removed; ephemeral)
  image: postgres:16 (same major as production; PG 16.13)
  volume_name: pg-restore-test-hb08-2026-05-15-data (now removed)
  network: bridge (default Docker bridge; NOT shared with production network `incomex_default` or any production container)
  isolation_verified:
    - distinct container name (no name collision with production `postgres`)
    - distinct volume name (no data collision)
    - no port published on host
    - bridge network is shared-with-other-containers only at network namespace level; PG was reachable only via `docker exec` from the host shell
  no_destructive_action_against_production: true
  duration_of_isolated_container: provisioned at 2026-05-15T10:25Z → restored → smoke-tested → torn down at ~10:28Z

4. Restore Test Procedure (Read-Only Against Production)

restore_test_steps:
  1_provision:
    command_summary: docker volume create $VOL; docker run -d --name $CT --network bridge -e POSTGRES_USER=directus -e POSTGRES_PASSWORD=<env> -e POSTGRES_DB=directus -v $VOL:/var/lib/postgresql/data postgres:16
    outcome: container UP after 1s; pg_isready PASS
  2_copy_dump:
    command_summary: docker cp <backup>.dump $CT:/tmp/restore.dump
    bytes_copied: 63,511,944
  3_restore:
    command_summary: docker exec $CT pg_restore -U directus -d directus --no-owner --no-privileges --clean --if-exists /tmp/restore.dump
    exit_code: 1
    stderr_summary: "1 ignored warning: role workflow_admin does not exist (CREATE USER MAPPING FOR workflow_admin); pg_restore: warning: errors ignored on restore: 1"
    classification_of_warning: NON-FATAL — pg_dump does not dump server-level roles by default; a CREATE USER MAPPING in the foreign-data wrapper layer references a role that exists only on production; restore proceeds with this single mapping skipped; data tables and schema-level objects all restored
    data_integrity_confirmed: TRUE (smoke tests below)
  4_smoke_test:
    table_count_query: "SELECT count(*) FROM information_schema.tables WHERE table_schema='public' AND table_type='BASE TABLE'"
    table_count_result: 236
    key_table_row_count_comparison_query: SELECT relname, n_live_tup FROM pg_stat_user_tables WHERE relname IN (10 key tables)
    key_tables_compared: 10
    matches_against_production_snapshot: 10/10 PASS
    detail:
      admin_fallback_log: production 22 / restored 22
      collection_registry: production 166 / restored 166
      dot_tools: production 309 / restored 309
      information_unit: production 98 / restored 98
      knowledge_documents: production 2802 / restored 2802
      tac_logical_unit: production 86 / restored 86
      tac_publication: production 3 / restored 3
      tac_unit_version: production 86 / restored 86
      tasks: production 10 / restored 10
      universal_edges: production 2199 / restored 2199
    hb_07_dot_pair_verification:
      query: "SELECT id, code, status, tier, paired_dot FROM dot_tools WHERE id IN (991, 992)"
      result:
        - 991 | DOT-IU-CUTTER | active | B | DOT-IU-CUTTER-VERIFY
        - 992 | DOT-IU-CUTTER-VERIFY | active | A | DOT-IU-CUTTER
      status: VERIFIED (DOT-pair survived restore with reciprocal paired_dot integrity)
  5_teardown:
    command_summary: docker stop $CT; docker rm $CT; docker volume rm $VOL
    verification: container count = 0; volume count = 0
    outcome: ephemeral environment cleanly removed

5. Restore Test Result

restore_test_result: PASS
acceptance_criteria_met:
  restored_db_starts_cleanly: TRUE (pg_isready PASS)
  sample_queries_return_expected_row_counts: TRUE (10/10 key tables match production snapshot)
  smoke_test_table_count_reasonable: TRUE (236 public tables, consistent with production scale)
  HB_07_dot_pair_survived: TRUE (id 991 + 992 present with correct shape)
  no_data_corruption_detected: TRUE (within sampled scope)
non_fatal_warnings:
  - CREATE USER MAPPING for role workflow_admin skipped (1 warning, ignored per pg_restore semantics); does not affect data
  - n_live_tup is approximate (pg_stat_user_tables); exact counts via SELECT count(*) would be even more precise but the n_live_tup approximation matches production snapshot exactly across 10 key tables
sign_off_authority_planned: G-4 (executor=Claude Code CLI / Agent; verifier=GPT) + operational DBA seat (when Đ37 names DBA seat at execution time)
sign_off_recorded_here: G-4 closure + GPT policy review (PASS upstream) + User / anh Huyên (sovereign authority via explicit prompt) + Opus / Agent (record-keeping)

6. Production Read-Only Confirmation

production_only_read:
  postgres_container_writes: NONE
  postgres_container_config_changes: NONE
  postgres_container_restarts: NONE
  directus_container_writes: NONE
  directus_container_config_changes: NONE
  directus_container_restarts: NONE
  any_other_production_container_touched: NONE
  vps_filesystem_writes:
    - /opt/incomex/backups/dieu44_hb08_2026-05-15/ (NEW dir; backup artefacts only; outside any container)
  no_destructive_command_run_against_production: TRUE
  pg_dump_is_read_only: TRUE (documented PostgreSQL behavior)
isolation_of_restore_test:
  separate_container: TRUE (pg-restore-test-hb08-2026-05-15)
  separate_volume: TRUE (pg-restore-test-hb08-2026-05-15-data)
  separate_network_target: bridge (no shared network with production containers)
  no_port_published: TRUE
  teardown_verified: TRUE (container + volume removed)

7. Acceptance Criteria

acceptance_criteria_for_hb_08:
  full_backup_artefact_produced:
    status: PRODUCED (63.5 MB; SHA-256 captured; pg_dump stderr empty)
  backup_recency:
    status: timestamp 2026-05-15T10:23:50Z (within minutes of execution prep window when HB-05 dry-run runs)
    note: per preflight plan §3 the backup must be < 60 min old at production execution start; this v0.1 closure record establishes the pattern; the production-execution-bound backup is a SEPARATE execution-phase artefact taken at execution prep time
  restore_test_passed:
    status: PASSED (236 tables; 10/10 key tables match production; HB-07 DOT-pair verified)
  restore_test_isolated:
    status: ISOLATED (separate container + volume; bridge network; torn down post-test)
  no_destructive_production_restore:
    status: confirmed
  checksum_recorded:
    status: RECORDED (SHA-256 = 7cadc5d6...)
  G_4_sign_off_recorded:
    status: SIGNED (executor + verifier sides per HB-06 seat naming)
hb_08_acceptance_state: ALL SEVEN criteria satisfied; closure_with_notes

8. Downstream Effects

downstream_effects_of_hb_08_closure:
  HB_05_rollback_test_plan_dry_run:
    status_before: blocked (terminal node; HB-08 + HB-09 + other prerequisites)
    status_after_hb_08_alone: still blocked (HB-09 also required; sibling closure in this batch)
    when_both_hb_08_and_hb_09_close: HB-05 transitions to ready_to_close (terminal node unblocked)
  pattern_proven_for_HB_05_dry_run_env:
    - the restore-test-pattern (isolated PG 16 container + same backup) was just demonstrated end-to-end
    - HB-09 will provision a persistent dry-run env using the same pattern
    - HB-05 26-scenario tests will run against the HB-09 dry-run env, NOT against production
  preflight_checklist_per_preflight_plan_§9:
    - directus_backup_taken: closed_with_notes (this closure)
    - directus_backup_restore_test_passed: closed_with_notes (this closure)

9. Status

HB_08_status: closed_with_notes
HB_08_closure_authority: G-4 DOT-Pair Signing Authority + operational DBA (assigned via Đ37; placeholder for v0.1 — same role-seat identifiers per HB-06)
HB_08_closure_signers:
  - G-4 DOT-Pair Signing Authority (executor=Claude Code CLI / Agent; verifier=GPT; secondary=Opus; human escalation=User / anh Huyên)
  - GPT (policy reviewer; PASS upstream on CTE batch)
  - User / anh Huyên (sovereign authority via explicit prompt)
  - Opus / Agent (record-keeping)

notes_carried_forward:
  - production-execution-bound backup will be a SEPARATE execution-phase artefact taken immediately before first DDL (< 60 min stale per preflight plan §3); this closure establishes the PATTERN + a v0.1 reference baseline for HB-05 dry-run
  - the 1 ignored pg_restore warning (workflow_admin role missing) is non-fatal and expected (pg_dump does not dump server-level roles by default); restoring into production rehydration would similarly need to recreate that role separately — that is an execution-phase operational task
  - the SHA-256 of the backup artefact is the integrity anchor; any future re-restore must compare against it before use
