dot-iu-cutter v0.1 — HB-01 / HB-02 / HB-03 / HB-04 Batch Closure Report

Date: 2026-05-15 Status: BATCH CLOSURE REPORT — 4 sign-off blockers closed_with_notes Trigger: GPT review of HB-06 returned PASS (2026-05-15). User has explicitly authorized batch closure of the 4 ready-to-close sign-off blockers (HB-01, HB-02, HB-03, HB-04). HB-08 and HB-09 are explicitly NOT in this batch (operational backup / snapshot / dry-run evidence; separate sessions). Scope: BATCH REPORT ONLY. No code, no DDL, no SQL, no migration, no PG mutation, no Directus mutation, no Qdrant/vector mutation, no backup, no snapshot, no dry-run, no execution.

5. Critical Path After Batch

[1] HB-06 — closed_with_notes (earlier today)
[2] HB-03 — closed_with_notes (THIS BATCH)
        ├─▶ HB-07 ← ready_to_close
        │     └─▶ CTE-02 ← still blocked
        └─▶ CTE-04 ← ready_to_close OR preparable
[3] HB-04 — closed_with_notes (THIS BATCH)
        └─▶ CTE-03 ← ready_to_close
[4] HB-09 — ready_to_close (separate operational session)
[5] HB-08 — ready_to_close (separate operational session)
[6] HB-01 — closed_with_notes (THIS BATCH)
[7] HB-02 — closed_with_notes (THIS BATCH)

⇒ HB-05 (rollback test plan dry-run + Đ32 + G-4 sign-off) — still blocked
   pre-requisites still open: HB-07, HB-08, HB-09, CTE-02, CTE-03, CTE-04

Remaining longest chain to HB-05:

HB-07 → CTE-02 → HB-05 (signal channel verification scenarios)
CTE-03 → HB-05 (canonicalization library scenarios)
CTE-04 → HB-05 (signing scheme scenarios)
HB-09 → HB-05 (dry-run environment)

Of these, HB-07 → CTE-02 is now the longest critical sub-chain (two sequential closures required after this batch).

7. Recommended Next Steps (NOT executed by Agent)

GPT review of this batch (5 files including this report).
If PASS → next closure sessions can run in parallel where possible:
- HB-07 (G-4 registers DOT-pair) — single session; unlocks CTE-02
- CTE-03 (engineering scaffolds canonicalization library) — single session; G-3 oversight
- CTE-04 (engineering implements signing scheme) — single session; G-4 oversight
- HB-08 (G-4 + DBA performs backup + restore test) — single operational session
- HB-09 (DBA + G-2 produces snapshots + dry-run environment) — single operational session
After HB-07 closes → CTE-02 (G-2 + G-4 wire signal channel).
After HB-07, HB-08, HB-09, CTE-02, CTE-03, CTE-04 all close → HB-05 (Đ32 + G-4 — 26-scenario rollback test plan dry-run + sign-off).
Re-run Final Readiness Review with closure artefacts attached.
If verdict transitions to authorize or authorize_with_conditions → explicit user prompt authorizing execution.
Only then: execution phase (FIRST DDL).

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