dot-iu-cutter v0.1 — P0 Blocker Closure Master Plan
Date: 2026-05-15 Status: BLOCKER CLOSURE PROGRAM — ACTIVE (CLOSURE PLANNING ONLY) Trigger: GPT review of Final Execution Readiness Package returned
PASS; readiness verdictdo_not_authorizestands; execution remains blocked. User has explicitly authorized opening the Blocker Closure Program phase. Scope: CLOSURE PLANNING ONLY. No code, no DDL, no SQL, no migration, no PG mutation, no Qdrant/vector mutation, no Directus mutation, no data write, no backup, no snapshot, no dry-run, no deploy. No blocker is closed in this phase except where the user explicitly prompts a specific closure.
1. Phase Scope
The Blocker Closure Program converts the 9 hard blockers (HB-01..HB-09) + 4 conditions-to-execute (CTE-01..CTE-04) recorded in the Final Readiness Blocker Register into a structured closure program with three workstreams, a dependency graph, an order of execution, and per-blocker acceptance criteria.
This phase plans closure work. It does not perform it.

5.1 Critical Path
The longest single chain is:
HB-06 (G-4 named)
→ HB-03 (X-6 sign-off)
→ HB-07 (DOT-pair registration)
→ CTE-04 (signing scheme v0.1 impl)
→ HB-05 (rollback test plan dry-run + Đ32 + G-4 sign-off)
→ Re-run Final Readiness Review
→ (gate may open conditionally; still requires user prompt)
Any closure work that parallelizes this chain reduces calendar time. HB-04 + CTE-03 form a parallel chain that ALSO feeds HB-05.
6. Three Workstreams
workstream_a_governance_seats_signoffs:
file: dot-iu-cutter-v0.1-p0-workstream-a-governance-seats-signoffs-2026-05-15.md
closures_addressed: [HB-06, HB-03, HB-07]
cross_cutting_owners: G-3 D4 intake (if needed), G-4 responsibilities, G-5 responsibilities, Đ37 dependency
primary_authority: Đ37 (seat naming) + G-4 (DOT-pair) + Đ44 (X-6 confirmation)
workstream_b_vocabulary_schema_canonicalization:
file: dot-iu-cutter-v0.1-p0-workstream-b-vocabulary-schema-canonicalization-2026-05-15.md
closures_addressed: [HB-01, HB-02, HB-04]
cross_cutting_decisions: [X-1, X-4, X-7]
primary_authority: Đ44 + Đ33/Đ43 (X-1) + Đ24 (X-2/X-4/X-7) — note X-2 already selected, X-3 already selected
workstream_c_infrastructure_preflight_dryrun:
file: dot-iu-cutter-v0.1-p0-workstream-c-infrastructure-preflight-dryrun-2026-05-15.md
closures_addressed: [HB-08, HB-09, HB-05, CTE-01, CTE-02, CTE-03, CTE-04]
primary_authority: G-4 + operational DBA + G-2 (signal channel) + Đ32 (HIGH-risk dry-run sign-off)
7. Order of Execution for Closure Work
sequence_overview:
step_1_start: HB-06 (operational seat naming under Đ37) — gates downstream A items + CTE-02
step_2_parallel:
- HB-01 (X-1 schema placement sign-off) — independent of HB-06
- HB-02 (X-4 Đ24 enum ratification + lookup population) — independent of HB-06
- HB-04 (X-7 canonicalization rule prose ratification) — independent of HB-06
- HB-08 (Directus backup + restore test) — independent of HB-06
- HB-09 (snapshots + dry-run environment) — independent of HB-06
step_3_after_G_4_named:
- HB-03 (X-6 dot_pair_signature shape sign-off) — requires G-4 named
- HB-07 (DOT-pair registration) — requires G-4 named
step_4_after_HB_04_ratified:
- CTE-03 (canonicalization rule library scaffolding) — uses prose from HB-04
step_5_after_HB_03_signed:
- CTE-04 (signing scheme v0.1 implementation) — uses shape from HB-03
step_6_after_G_2_named:
- CTE-02 (signal routing wired) — uses G-2 channel
step_7_after_all_preconditions:
- HB-05 (rollback test plan dry-run + Đ32 + G-4 sign-off) — depends on HB-06, HB-03, HB-07, HB-09, CTE-02, CTE-03, CTE-04
step_8:
- Re-run Final Readiness Review (separate session)
step_9:
- if re-run verdict transitions to authorize / authorize_with_conditions → explicit user prompt to authorize execution
step_10:
- execution phase (FIRST time DDL/SQL/migration is allowed)
8. What Can Run in Parallel
parallel_workstreams_possible:
- workstream A item HB-06 + workstream B items HB-01, HB-02, HB-04 + workstream C items HB-08, HB-09
- HB-04 + CTE-03 form a parallel chain to HB-06 → HB-03 → HB-07 → CTE-04
sequential_constraints_within_critical_path:
- HB-06 must close G-4 named before HB-03 / HB-07 can close
- HB-03 must close before CTE-04 can close
- HB-07 must close before HB-05 dry-run scenarios involving DOT-pair signatures
- HB-04 must close before CTE-03 can close
- HB-09 must close before HB-05 dry-run executes (needs dry-run environment)
- CTE-02 wiring must close before HB-05 scenarios that observe signal channels
- HB-05 must close LAST before Final Readiness Review re-run
must_be_sequential:
- HB-06 G-4 → HB-03 → HB-07 → CTE-04 → HB-05
- HB-04 → CTE-03 → HB-05
- HB-09 → HB-05
- HB-06 G-2 → CTE-02 → HB-05
parallel_to_critical_path:
- HB-01 schema placement (independent of seat naming; needed for first DDL but not for HB-05 dry-run if dry-run uses an isolated environment)
- HB-02 Đ24 enums + lookup population (independent of seat naming; needed for first DDL)
- HB-08 backup + restore test (independent; needed for production execution)
9. What Remains Forbidden in This Phase
forbidden_in_this_phase:
- actually naming any seat
- actually creating any role
- actually registering any DOT
- actually signing off any cross-cutting decision
- actually ratifying any Đ24 / Đ44 / Đ33/Đ43 artefact
- actually taking any backup
- actually taking any snapshot
- actually provisioning any environment
- actually scaffolding any library
- actually implementing any signing scheme
- actually wiring any signal channel
- actually executing any dry-run
- actually writing any DDL / SQL / migration script
- actually mutating PG / Qdrant / Directus
- actually authorizing execution
- self-advancing to execution
