2. Status per CTE

CTE_02_status: closed_with_notes
  rationale: routing convention + signal coverage + emission binding documented; G-2 channel ownership attributed; v0.1 interim sink path convention bound; FUTURE sink (decision_backlog_entry post P0-5) bound; capability proof deferred to HB-05 dry-run
  not_blocked_requires_design: TRUE — no architecture is missing; the deferred items are runtime wiring (after signal emitters exist) and capability proof (via HB-05 dry-run)
  channel_owner: G-2 = GPT (primary); Opus (backup); User / anh Huyên (escalation)
  signals_covered:
    - dot_pair_drift (executor_tool_revision ≠ verifier_tool_revision)
    - signature_failure (missing/invalid signature + tool_revision_mismatch)
    - signature_revoked (lifecycle revoked transition; out-of-CTE-02-but-uses-same-channel)
    - rollback_failed (separate kind; uses same channel; out of CTE-02 scope)
  no_signal_emitted: TRUE
  no_PG_trigger_or_Directus_flow_installed: TRUE
  no_row_written_to_any_sink: TRUE

CTE_03_status: closed_with_notes
  rationale: reference implementation (pseudo-code + tokenization rule + determinism properties) scaffolded inside the closure record; aligned with HB-04 ratified canon-md-v0.1.0 prose; ready to be transcribed to engineering tree at execution-phase deployment
  not_blocked_requires_design: TRUE — HB-04 prose is complete and the v0.1 scope (markdown only) is bound; only deployment is deferred
  scaffold_form: pseudo-code in closure record (no repository file committed)
  behavior_specified:
    - NFC unicode normalization
    - CR / CRLF → LF
    - trailing whitespace trim per line (space U+0020 + tab U+0009 only)
    - exactly one trailing LF
    - canonical_token stream (per-line, whitespace-split; (line_index, intra_line_token_index) position form)
    - byte_span → canonical_token_position mapping
    - axis_1_drift_count under canonical_token unit
    - canonicalization_rule_used = "canon-md-v0.1.0" returned per output
  determinism_idempotency_properties: specified for HB-05 dry-run scenarios S19 + S20 to verify
  no_code_committed_to_repository: TRUE
  no_canonicalization_run_in_production: TRUE

CTE_04_status: closed_with_notes
  rationale: reference implementation (pseudo-code) scaffolded inside the closure record; aligned with HB-03 X-6 polished shape + HB-07 DOT-pair registration; ready to be transcribed to engineering tree at execution-phase deployment with G-4 oversight
  not_blocked_requires_design: TRUE — HB-03 shape and HB-07 DOTs are bound; only deployment is deferred
  scheme_form: hash-based pseudo-signature (SHA-256 over canonical-JSON-serialized payload_envelope); SIGNING_SCHEME_VERSION = "v0.1.0-hash-based-pseudo"
  required_fields_covered:
    - payload_hash (SHA-256 of canonical JSON)
    - tool_revision (signer_tool_revision; drift rule binding inherited from HB-07 §6)
    - signer_dot (DOT-IU-CUTTER or DOT-IU-CUTTER-VERIFY; dot_tools id 991 or 992)
    - signature_kind (executor_cut, verifier_cut, executor_verify, verifier_verify; Đ24 ratification pending per HB-02)
    - signature_status (validation_state ∈ pending, valid, invalid, revoked; Đ24 ratification pending per HB-02)
    - timestamp (signed_at; ISO-8601 UTC)
  contract_functions:
    - build_payload_envelope() — enforces exactly-one cross-reference rule
    - compute_payload_hash() — deterministic; SHA-256
    - build_signature_payload() — deterministic concatenation
    - sign() — orchestrates above; returns dot_pair_signature row payload matching HB-03 polished shape
    - verify_signature() — returns {valid | invalid_payload_hash | invalid_payload_envelope | invalid_signature_payload}; emits signature_failure on invalid
  no_code_committed_to_repository: TRUE
  no_signature_generated: TRUE
  cryptographic_upgrade_FUTURE: PEF-04 via G-3 D4 capability intake

4. Downstream Effects

hard_blockers_status_delta:
  hb_05: still blocked (terminal)
    waits_on_remaining: HB-08, HB-09
    note: CTE-02 + CTE-03 + CTE-04 were three prerequisites; all now closed_with_notes; HB-05 still cannot close until HB-08 + HB-09 also close
  hb_06_hb_07_hb_01_hb_02_hb_03_hb_04: unchanged (closed_with_notes from earlier sessions)
  hb_08_hb_09: unchanged (operational; ready_to_close; separate sessions per user prompt)

  cte_01: planning_closed (unchanged from implementation planning phase)
  cte_02: blocked → closed_with_notes (THIS BATCH)
  cte_03: blocked → closed_with_notes (THIS BATCH)
  cte_04: blocked → closed_with_notes (THIS BATCH)

post_batch_aggregate:

4.1 HB-05 Dependency Status (Post Batch)

HB_05_dependencies_per_workstream_C_§5:
  HB_06_G_4_named: closed_with_notes (HB-06)
  HB_06_G_2_named: closed_with_notes (HB-06)
  HB_03_X_6_polish_signed: closed_with_notes (HB-03)
  HB_07_DOT_pair_registered: closed_with_notes (HB-07)
  HB_09_dry_run_environment: ready_to_close (operational; separate session)
  HB_04_canonicalization_prose: closed_with_notes (HB-04)
  CTE_02_signal_routing_wired: closed_with_notes (THIS BATCH; capability proof at dry-run)
  CTE_03_canonicalization_library_scaffolded: closed_with_notes (THIS BATCH; spec ready for transcription to dry-run env)
  CTE_04_signing_scheme_implementation: closed_with_notes (THIS BATCH; spec ready for transcription to dry-run env)
HB_05_remaining_blockers: HB-08 (backup + restore test) + HB-09 (snapshots + dry-run environment)

4.2 Critical Path Update

[1] HB-06 — closed_with_notes
[2] HB-07 — closed_with_notes
[3] HB-01 / HB-02 / HB-03 / HB-04 — closed_with_notes
[4] CTE-02 / CTE-03 / CTE-04 — closed_with_notes (THIS BATCH)
[5] HB-08 — ready_to_close (operational; separate session)
[6] HB-09 — ready_to_close (operational; separate session)
[7] HB-05 — still blocked (terminal); waits on HB-08 + HB-09
  └▶ Re-run Final Readiness Review
       └▶ Explicit user prompt
            └▶ Execution phase (first DDL)

Critical sub-chain into HB-05 has narrowed to just HB-08 → HB-05 and HB-09 → HB-05. Both are operational sessions (backup + restore test; snapshots + dry-run environment). Once both close, HB-05 can execute the 26-scenario rollback test plan dry-run using the spec-prose artefacts from CTE-03 and CTE-04, observing signals via CTE-02's routing convention.

6. Recommended Next Steps (NOT executed by Agent)

1. GPT review of this CTE batch (4 files including this report).
2. If PASS → open the two remaining operational sessions:
   • HB-08 (G-4 + operational DBA: Directus PG full backup + restore test). Separate explicit-prompt session.
   • HB-09 (operational DBA + G-2: pg_dump --schema-only + per-table row-count snapshot + dry-run environment provisioning). Separate explicit-prompt session.
3. After HB-08 + HB-09 close → engineering transcription session for CTE-03 + CTE-04 reference implementations into the dry-run environment (separate explicit prompt; G-4 oversight for CTE-04).
4. HB-05 (Đ32 + G-4: 26-scenario rollback test plan dry-run + sign-off). The terminal closure; uses CTE-02 routing convention, CTE-03 scaffold, CTE-04 scheme.
5. Re-run Final Readiness Review with all closure artefacts attached.
6. If verdict transitions to authorize or authorize_with_conditions → explicit user prompt authorizing execution.
7. Only then: execution phase (FIRST DDL on cutter_governance schema).

Each numbered step above is a separate phase or session, not part of this CTE batch.
