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

Date: 2026-05-15 Status: BLOCKER CLOSURE PROGRAM — Dashboard Scope: PLANNING DOCUMENTATION ONLY. No closure performed. Master: blocker-closure/dot-iu-cutter-v0.1-p0-blocker-closure-master-plan-2026-05-15.md

1. Purpose

Provide a single-table view of all 9 hard blockers (HB-01..HB-09) and 4 conditions-to-execute (CTE-01..CTE-04). For each:

  • status (open / ready_to_close / blocked / deferred)
  • owner
  • upstream dependency
  • closure artefact required
  • whether it blocks the first DDL
  • next action
  • whether it sits on the critical path

Status definitions:

  • open — work not yet started; ready to start when dependencies allow
  • ready_to_close — all dependencies satisfied; closure work can begin now
  • blocked — dependency on another blocker not yet closed
  • deferred — does not need to close for v0.1 P0 (e.g., G-1, G-3 seats; FUTURE items)

Today's snapshot has no closures performed, so all entries are either ready_to_close (independent items) or blocked (items waiting on upstream).

4. Conditions-to-Execute Dashboard

ID Title Status Owner Upstream dependency Closure artefact Blocks first DDL Next action Critical path
CTE-01 Failure-stop rule enforced at execution time planning_closed; execution_open G-4 + operational DBA none (planning-level documented per preflight plan §8) execution-time tool/runbook enforces failure-stop no for planning; yes at execution-time for production safety nothing in this phase; execution-phase runbook task not on critical path (execution-time)

closed_today_completely: 0

5. Post-Execution Follow-ups Dashboard (do NOT block first DDL)

ID Title Status Owner Blocks first DDL
PEF-01 canonical_address backfill deferred G-2 + DBA no
PEF-02 canonical_address NOT NULL enable post-backfill deferred DBA + G-2 no
PEF-03 PG-constraint dual-signature enforcement deferred G-4 + Đ32 no
PEF-04 Cryptographic signing scheme upgrade deferred G-3 + G-4 + Đ32 no
PEF-05 Per-source_kind canonicalization extensions deferred Đ24 + G-3 no
PEF-06 axis-2 elevation review deferred G-3 + Đ32 no
PEF-07 Markdown mirror generator deferred G-2 + Đ37 no
PEF-08 PG jsonb_check rollout deferred Đ44 + Đ24 + engineering no
PEF-09 DOT-pair separate execution context implementation deferred G-3 + G-4 + Đ32 no

All PEF items are deferred because they are FUTURE / post-execution and do NOT block first DDL. They are tracked here for completeness.

6. Critical Path Visualization

The critical path is the longest chain of dependencies that must be sequentially closed before the execution gate can become conditionally openable:

critical_path_summary:
  primary_chain: HB-06 G-4 → HB-03 → HB-07 → CTE-04 → HB-05
  parallel_required_chain_1: HB-04 → CTE-03 → HB-05
  parallel_required_chain_2: HB-06 G-2 → CTE-02 → HB-05
  parallel_required_chain_3: HB-09 → HB-05
  terminal_node: HB-05 (rollback test plan dry-run + sign-off)
  followed_by: re-run Final Readiness Review → explicit user prompt → execution phase

parallel_independent_to_critical_path:
  - HB-01 (schema placement sign-off) — independent of seat naming; needed for first DDL but NOT for HB-05 dry-run if dry-run uses isolated environment
  - HB-02 (Đ24 enum ratification + lookup population) — independent of seat naming; needed for first DDL
  - HB-08 (backup + restore test) — independent of HB-05 dry-run; needed for production execution

minimum_calendar_chain_to_close: HB-06 G-4 + HB-03 + HB-07 + CTE-04 + HB-05 (each requires its own session; some can overlap if parallel chains are scheduled correctly)

7. Next Action Per Blocker (Compact)

next_actions_today:
  HB-01: open Đ44 + Đ33/Đ43 session
  HB-02: open Đ24 session for enum-set ratification; schedule operational lookup population
  HB-04: open Đ24 + Đ44 session for canonicalization prose ratification
  HB-06: open Đ37 operational session to name G-2, G-4, G-5 (recommended first action)
  HB-03: wait for HB-06 G-4
  HB-05: wait for all upstream
  HB-07: wait for HB-06 G-4 + HB-03
  HB-08: wait for HB-06 G-4
  HB-09: wait for HB-06 G-2
  CTE-01: planning-level closed; execution-phase concern
  CTE-02: wait for HB-06 G-2/G-4 + HB-07
  CTE-03: wait for HB-04
  CTE-04: wait for HB-06 G-4 + HB-03
