dot-iu-cutter v0.1 — P0 Blocker Closure Report

Date: 2026-05-15 Status: BLOCKER CLOSURE PROGRAM — REPORT (FINAL OF THIS PHASE) Scope: PLANNING DOCUMENTATION ONLY. No closure performed. No execution. Master: blocker-closure/dot-iu-cutter-v0.1-p0-blocker-closure-master-plan-2026-05-15.md

1. Purpose

Final report for the Blocker Closure Program phase. Lists files created, the recommended closure sequence, what can run in parallel, what must be sequential, which blocker to close first, whether the execution gate can open, and the explicit status flags required by the user's instructions.

3. Recommended Closure Sequence

Per the user's instruction and the critical-path analysis in the dashboard §6:

recommended_sequence:
  step_1:
    action: open Đ37 operational session to name G-2, G-4, G-5
    closes: HB-06 (subset)
    rationale: G-4 named unlocks HB-03 / HB-07 / HB-08 / CTE-04; G-2 named unlocks CTE-02 / HB-09 artefact recording; G-5 named unlocks PII policy
    sequential_constraint: required as first action (it is the root of the critical path)

  step_2_parallel_with_step_1:
    actions:
      - prepare HB-01 sign-off materials (Đ44 + Đ33/Đ43)
      - prepare HB-02 sign-off materials (Đ24 enum sets) and schedule operational lookup population
      - prepare HB-04 canonicalization prose materials (Đ24 + Đ44)
      - prepare HB-08 backup procedure (planning materials; execution waits for G-4)
      - prepare HB-09 snapshot procedures and dry-run environment provisioning plan (planning materials; execution waits for G-2)
    closes: nothing immediately; preparation reduces the time to close once authorities convene
    rationale: HB-01, HB-02, HB-04 are independent of HB-06; preparation in parallel reduces calendar time
    can_run_in_parallel: yes

  step_3_after_G_4_named:
    actions:
      - close HB-03 (G-4 + Đ44 sign-off X-6 polish)
    closes: HB-03
    rationale: HB-03 sign-off requires G-4 named; once signed, HB-07 and CTE-04 unblock
    sequential_constraint: must wait for HB-06 G-4 named

  step_4_after_HB_03_signed:
    actions:
      - close HB-07 (G-4 registers DOT-pair + drift rule binding)
    closes: HB-07
    rationale: registered DOTs reference the signed shape
    sequential_constraint: must wait for HB-03

  step_5_in_parallel_with_steps_3_4:
    actions:
      - close HB-01 once Đ44 + Đ33/Đ43 sign off
      - close HB-02 ratification half once Đ24 ratifies enum sets
      - close HB-04 once Đ24 + Đ44 ratify canonicalization prose
    closes: HB-01, HB-02 (ratification half), HB-04
    rationale: independent authorities; can proceed concurrently

  step_6_after_HB_04_and_HB_03:
    actions:
      - close CTE-03 once HB-04 prose available (engineering scaffolds canonicalization library)
      - close CTE-04 once HB-03 shape signed (engineering implements signing scheme; G-4 oversight)
    closes: CTE-03, CTE-04
    sequential_constraint:
      - CTE-03 must wait for HB-04
      - CTE-04 must wait for HB-03 (and G-4 named)

  step_7_after_G_2_named_and_HB_07:
    actions:
      - close CTE-02 (G-2 wires channel; G-4 binds emission)
    closes: CTE-02
    sequential_constraint: must wait for HB-06 G-2 + HB-07 (so emission references registered DOTs)

  step_8_parallel:
    actions:
      - close HB-08 once G-4 named + DBA performs backup + restore test
      - close HB-09 once G-2 named + DBA produces snapshots + dry-run environment
      - close HB-02 lookup-population operational half once Đ24 ratification done
    closes: HB-08, HB-09, HB-02 (operational half)
    rationale: infrastructure prep parallelizes the governance chain

  step_9_FINAL:
    actions:
      - execute the 26-scenario rollback test plan dry-run in the dry-run environment
      - Đ32 (HIGH-risk path) + G-4 sign off the dry-run outcomes
    closes: HB-05
    prerequisites: HB-06 (G-2/G-4 named), HB-03, HB-07, HB-09, HB-04, CTE-02, CTE-03, CTE-04 ALL closed
    sequential_constraint: LAST closure before re-running Final Readiness Review

  step_10_re_review:
    action: re-run Final Readiness Review with closure artefacts attached
    closes: none (review only); emits new readiness verdict
    expected_outcome: verdict may transition to authorize or authorize_with_conditions

  step_11_authorization:
    action: explicit user prompt authorizing execution
    closes: execution gate
    sequential_constraint: required regardless of all other closures

  step_12_execution_phase:
    action: execution phase begins (FIRST TIME DDL/SQL/migration is allowed)
    note: this phase is OUT OF SCOPE for the entire dot-iu-cutter v0.1 P0 planning lineage; it is a future phase

4. What Can Run in Parallel

parallelizable_workstreams:
  workstream_b_items_HB_01_HB_02_HB_04:
    - all three are mutually independent
    - all three can run in parallel with HB-06 (Workstream A)
    - all three can run in parallel with HB-08 / HB-09 prep (Workstream C)
  preparation_before_seat_naming:
    - HB-01 materials drafted by Đ44 + Đ33/Đ43 work groups
    - HB-02 enum sets drafted by Đ24 vocab owner
    - HB-04 prose drafted (canonicalization rule planning note already authored as input)
  after_G_4_named:
    - HB-03 + HB-08 can begin simultaneously
    - HB-07 sequential after HB-03 sign-off
    - CTE-04 sequential after HB-03 + G-4 named
  after_HB_04:
    - CTE-03 begins
  after_G_2_named:
    - HB-09 begins
    - CTE-02 channel wiring prep

5. What Must Be Sequential

sequential_constraints:
  - HB-06 G-4 named MUST precede HB-03 (G-4 sign-off authority)
  - HB-06 G-4 named MUST precede HB-07 (G-4 registers DOTs)
  - HB-06 G-4 named MUST precede HB-08 sign-off (G-4 + DBA)
  - HB-06 G-2 named MUST precede CTE-02 (G-2 channel ownership)
  - HB-06 G-2 named MUST precede HB-09 artefact recording (G-2 records snapshot)
  - HB-03 MUST precede HB-07 (registry references signed shape)
  - HB-03 MUST precede CTE-04 (signing scheme references signed shape)
  - HB-07 MUST precede CTE-02 (channel emission references registered DOTs)
  - HB-04 MUST precede CTE-03 (scaffolding implements ratified prose)
  - HB-09 MUST precede HB-05 (dry-run environment exists)
  - CTE-02, CTE-03, CTE-04 MUST precede HB-05 (scenarios depend on channel + canon + signatures)
  - HB-05 MUST precede re-run Final Readiness Review
  - re-run Final Readiness Review MUST precede execution authorization
  - explicit user prompt MUST precede execution-phase opening

6. Which Blocker to Close First

first_blocker_to_close: HB-06 (operational seats G-2, G-4, G-5 named under Đ37)
rationale:
  - HB-06 is the root of the critical path
  - HB-06 G-4 named unlocks 4 downstream closures (HB-03, HB-07, HB-08, CTE-04)
  - HB-06 G-2 named unlocks 2 downstream closures (CTE-02, HB-09 artefact recording)
  - HB-06 G-5 named unlocks PII boundary policy for all P0 steps writing identifiers
  - independent of any other blocker; Đ37 authority is sovereign
  - has no upstream dependency
  - starting HB-06 immediately maximizes parallel work downstream

7. Execution Gate Status

execution_gate_status: closed (unchanged)
execution_authorized: false
gate_can_become_conditionally_openable_only_when:
  - all 9 hard blockers HB-01..HB-09 demonstrably closed
  - CTE-02, CTE-03, CTE-04 physically present (CTE-01 is planning-level closed; execution-time enforcement is execution-phase)
  - HB-05 26-scenario dry-run executed with 100% pass rate
  - GPT review PASS on the closure artefacts (separate review session)
  - re-run Final Readiness Review verdict transitions to authorize or authorize_with_conditions
  - explicit user prompt authorizing execution (separate prompt)
gate_does_not_open_implicitly: true
self_advance_to_execution: prohibited

9. Recommended Next Steps (NOT executed by Agent)

GPT review of this Blocker Closure Program (6 files).
If PASS → open the first explicit-prompt closure session: HB-06 (Đ37 operational session naming G-2, G-4, G-5). This is a separate phase with its own explicit prompt.
In parallel with #2: open Đ44 + Đ33/Đ43 session for HB-01, Đ24 session for HB-02, and Đ24 + Đ44 session for HB-04. Each is a separate explicit-prompt session.
After HB-06 G-4 named → open closure session for HB-03, then HB-07.
After HB-04 ratified → open engineering session for CTE-03. (engineering work; separate phase boundary may apply)
After HB-03 signed + G-4 named → open engineering session for CTE-04.
After HB-06 G-2 named + HB-07 registered → wire CTE-02 channel.
After HB-06 G-4 named → DBA performs HB-08 backup + restore test; DBA + G-2 produce HB-09 snapshots + dry-run environment.
After all upstream closed → execute HB-05 26-scenario dry-run; Đ32 + G-4 sign off.
Re-run Final Readiness Review with closure artefacts attached.
If verdict transitions to authorize / authorize_with_conditions → explicit user prompt to authorize execution.
Only then: execution phase (FIRST DDL).

Each numbered step above is a separate phase or session, not part of this Blocker Closure Program planning.
