1. What Was Inspected

inspection_targets:
  - existing DOT registry location (Directus collection `dot_tools`)
  - existing paired-DOT pattern (S178 A+3 reference: DOT-HC-EXECUTOR ↔ DOT-HC-EXECUTOR-VERIFY at ids 965/966)
  - existing entries for `dot-iu-cutter` / `dot-iu-cutter-verify` (none found)
  - dot_tools schema (28 fields)
  - valid domain enum (FK collection; values include governance.audit, monitoring.health, infrastructure.*, data_quality, lifecycle, ...)

inspection_results:
  directus_health: ok (https://directus.incomexsaigoncorp.vn)
  registry_collection: dot_tools
  registry_schema_fields:
    - id, code, name, name_en, description, status, tier, domain, classification, category, token_type, owner
    - paired_dot, _dot_origin, extra_metadata (JSON)
    - operation, trigger_type, cron_schedule, file_path, last_executed, coverage_status, usage_count, sort, script_path
  paired_pattern_reference:
    DOT-HC-EXECUTOR (id 965, tier B, paired_dot=DOT-HC-EXECUTOR-VERIFY)
    DOT-HC-EXECUTOR-VERIFY (id 966, tier A, paired_dot=DOT-HC-EXECUTOR)
  pre_existing_iu_cutter_entries: none
  domain_value_chosen: governance.audit (closest match in valid enum; cutter is governance-criterion-28 binding)

  - registry mechanism confirmed established (dot_tools collection + S178 A+3 paired-DOT pattern)
  - no collision risk (codes DOT-IU-CUTTER / DOT-IU-CUTTER-VERIFY did not previously exist)
mutation_rows_created:
  - dot_tools id=991 (DOT-IU-CUTTER)
  - dot_tools id=992 (DOT-IU-CUTTER-VERIFY)
mutation_NOT_performed:
  - no schema created
  - no P0 DDL written
  - no P0 migration executed
  - no PG mutation outside Directus dot_tools
  - no Qdrant / vector mutation
  - no business data mutation
  - no tac_logical_unit row touched
  - no other dot_tools row touched
  - no signing scheme implemented
  - no signal channel wired
  - no rollback dry-run
  - no backup taken
  - no snapshot taken

3. Registry Location

registry_location:
  system: Directus
  url: https://directus.incomexsaigoncorp.vn
  collection: dot_tools
  pattern: S178 A+3 paired-DOT (executor / verifier reciprocal paired_dot)
  rows_created:
    executor:
      id: 991

      status: active
      token_type: ai
      _dot_origin: SUSPECT:dieu44_hb07_dot_pair_registration_2026-05-15 (Directus prepends SUSPECT: for non-standard origins; not a failure flag — matches HC pair convention)
      date_created: 2026-05-15T10:05:06
    verifier:
      id: 992

  reciprocal_integrity: verified (991.paired_dot=DOT-IU-CUTTER-VERIFY AND 992.paired_dot=DOT-IU-CUTTER)

4. DOT-Pair Details

4.1 Executor (DOT-IU-CUTTER, id 991)

code: DOT-IU-CUTTER
identity: Claude Code CLI / Agent
role: executor
performs:
  - MARK
  - CUT
  - internal pre-VERIFY
  - emits executor_cut + executor_verify signatures per HB-03 X-6 shape
governance_seat: G-4 DOT-Pair Signing Authority (HB-06 seat-named 2026-05-15; executor side = Claude Code CLI / Agent)
secondary_reviewer: Opus
human_escalation: User / anh Huyên
tier: B (per S178 A+3 convention; "B" = batch executor side)

4.2 Verifier (DOT-IU-CUTTER-VERIFY, id 992)

code: DOT-IU-CUTTER-VERIFY
identity: GPT
role: verifier
performs:
  - independent VERIFY in separate execution context (per D1 §4.7 + §4.14)
  - axis-1 round-trip drift measurement under axis_1_drift_unit=canonical_token (X-A)
  - axis-2 advisory coverage assessment (v0.1 advisory)
  - emits verifier_cut + verifier_verify signatures per HB-03 X-6 shape
governance_seat: G-4 DOT-Pair Signing Authority (verifier side = GPT)
secondary_reviewer: Opus
human_escalation: User / anh Huyên
tier: A (per S178 A+3 convention; "A" = audit/verifier side)

5. Executor / Verifier Boundary

executor_role:
  performs: MARK, CUT, internal pre-VERIFY
  signature_kinds: executor_cut, executor_verify (per HB-03 X-6 shape)
  identity: DOT-IU-CUTTER (Claude Code CLI / Agent)
verifier_role:
  performs: independent VERIFY in separate execution context
  signature_kinds: verifier_cut, verifier_verify (per HB-03 X-6 shape)
  identity: DOT-IU-CUTTER-VERIFY (GPT)
joint_pass_requirement:
  - executor signature on CUT result (signature_kind=executor_cut, validation_state=valid)
  - verifier signature on independent VERIFY result (signature_kind=verifier_verify, validation_state=valid)
  - both signatures present + tool_revision_match=true → REPORT may emit PASS / cut_change_set → committed
  - any divergence → verdict=NEEDS_HUMAN
boundary_policy_status: bound here at planning level (v0.1 application-layer); full separate-execution-context implementation FUTURE per PEF-09 + G-3 D4 capability intake

6. tool_revision Drift Rule (inherited from HB-03)

tool_revision_drift_rule:
  rule: executor_tool_revision MUST equal verifier_tool_revision for valid co-sign
  enforcement_at_runtime:
    detection: at CUT pre-check + at VERIFY verdict computation
    response:
      cut_side: state=invalid_drift on cut_change_set; CUT cannot transition to committed; dot_pair_drift signal emit
      verify_side: verdict=NEEDS_HUMAN on verify_result; escalation_ref populated
  channel_emission_point: bound to DOT-IU-CUTTER + DOT-IU-CUTTER-VERIFY via this registration (HB-07); channel wiring proper is CTE-02 (pending HB-07 → CTE-02 next step)
rotation_policy:
  trigger: planned tool_revision upgrade per G-3 D4 capability intake
  authority: G-4 Custodian + Council
  Đ32_review_required_if_mid_cycle: YES
revocation_policy:
  trigger: suspected compromise, signature failure cluster, security incident
  authority: G-4 Custodian + Đ32 full escalation + Council
  immediate_action: pause CUT operations; existing manifests remain; rollback if mid-cycle
note: rotation / revocation policies are bound at G-4 governance level; HB-07 registers the pair only — actual rotation / revocation events are separate sessions

8. Downstream Effects

downstream_effects_of_hb_07_closure:
  CTE_02_signal_routing:
    status_before: blocked (waited on HB-07 — channel emission references registered DOTs)
    status_after: ready_to_close (DOT-pair registered)
    next_action: open separate session for G-2 (channel owner=GPT, backup=Opus) + G-4 (executor=Claude Code CLI / Agent, verifier=GPT) to wire dot_pair_drift / signature_failure channels to the G-2 backlog (G-2 channel wiring + emission binding test)
    note: CTE-02 is NOT closed by this closure

  CTE_04_signing_scheme_v0_1:
    status_before: ready_to_close (independent post HB-03; not gated by HB-07 directly)
    status_after: still ready_to_close
    note: CTE-04 is NOT closed by this closure; HB-07 does NOT implement the signing scheme

  HB_05_rollback_test_plan_dry_run:
    status_before: blocked (terminal node)
    status_after: still blocked (HB-08, HB-09, CTE-02, CTE-03, CTE-04 all remain open)
    note: HB-05 is NOT closed by this closure; many upstream remain

  HB_08_directus_backup_restore_test:
    status_change: none (independent of HB-07)
  HB_09_snapshots_dry_run_environment:
    status_change: none (independent of HB-07)
  CTE_03_canonicalization_library_scaffolding:
    status_change: none (independent of HB-07)

what_HB_07_does_NOT_do:
  - implement the signing scheme (CTE-04 remains OPEN; separate engineering session)
  - wire any signal channel (CTE-02 remains OPEN; now ready_to_close)
  - implement canonicalization library (CTE-03 remains OPEN; separate session)
  - take any backup (HB-08 remains OPEN)
  - take any snapshot (HB-09 remains OPEN)
  - execute rollback dry-run (HB-05 remains OPEN)
  - emit any production signature
  - rotate / revoke any registered DOT (policy bound; events deferred to separate sessions)
  - create any P0 schema or table
  - write any P0 DDL or migration

  hb_07: ready_to_close → closed_with_notes (THIS CLOSURE)

cte_status_delta:
  cte_02: blocked → ready_to_close (unlocked by HB-07)

hard_blockers_closed_total_now: 6 of 9 (HB-01, HB-02, HB-03, HB-04, HB-06, HB-07)
hard_blockers_still_open: 3 (HB-05, HB-08, HB-09)

9. Status

HB_07_status: closed_with_notes
HB_07_closure_authority: G-4 DOT-Pair Signing Authority (executor=Claude Code CLI / Agent; verifier=GPT; secondary=Opus; human escalation=User / anh Huyên)
HB_07_closure_signers:
  - G-4 DOT-Pair Signing Authority (executor side + verifier side)
  - GPT (policy reviewer; PASS upstream on batch closure)
  - User / anh Huyên (sovereign authority via explicit prompt)
  - Opus / Agent (record-keeping)

registry_writes_performed:
  - dot_tools.id=991 (DOT-IU-CUTTER, executor, tier B, paired_dot=DOT-IU-CUTTER-VERIFY)
  - dot_tools.id=992 (DOT-IU-CUTTER-VERIFY, verifier, tier A, paired_dot=DOT-IU-CUTTER)

execution_authorized: false
p0_migration_allowed: false
ddl_allowed: false
production_cut_authorized: false
production_verify_authorized: false

notes_carried_forward:
  - DOT-pair is registered_for_p0_planning_or_ready; NOT yet authorized for production CUT / VERIFY
  - signing scheme v0.1 (hash-based pseudo-signature) implementation is CTE-04 (engineering session; G-4 oversight)
  - signal channel wiring (dot_pair_drift / signature_failure → G-2) is CTE-02 (now ready_to_close)
  - canonicalization rule library scaffolding is CTE-03 (ready_to_close post HB-04)
  - cryptographic signing scheme upgrade is FUTURE per PEF-04 via D4 capability intake
  - separate execution context for verifier is FUTURE per PEF-09 via G-3 D4 capability intake
  - PG-constraint enforcement of dual-signature rule is FUTURE per PEF-03
  - Directus prepends "SUSPECT:" to _dot_origin for non-standard origins; matches HC pair convention; not a failure flag
  - owner field left null (governance role-seat per HB-06 captured in description + extra_metadata; operational owner naming is Đ37-territory and does not block HB-07)
  - rotation / revocation events are separate sessions; policies bound at G-4 governance level via HB-06 + this closure
