dot-iu-cutter v0.1 — X-A Ratification Closure GPT Review

Reviewer: GPT
File reviewed: knowledge/dev/laws/dieu44-trien-khai/ratification/dot-iu-cutter-v0.1-x-a-source-span-drift-unit-ratification-2026-05-15.md
Scope: Review only. No implementation, no migration, no PG mutation.

1. Verdict

x_a_ratification_closure_status: PASS
agent_revision_needed: false
X_A_status: closed_with_notes
implementation_planning_gate_status: OPEN_PENDING_EXPLICIT_PROMPT_APPROVAL
implementation_allowed: false
implementation_execution_allowed: false
next_phase: implementation_planning_phase

The X-A ratification closure correctly records the selected option and closes the sole design-level blocker identified in the Đ32 P0 Risk Review package.

2. Confirmed Binding Decision

source_span_unit: byte_offsets
axis_1_drift_unit: canonical_token
conversion_required: true
conversion_basis: canonicalization_rule_v0_1
canonicalization_rule_v0_1_placeholder: NFC unicode normalization + LF line endings + trailing whitespace trim for markdown v0.1

The decision preserves precise source spans while using canonical-token drift to avoid false drift from whitespace and line-ending changes.

3. Gate Effect

design_level_blockers_remaining: 0
implementation_planning_gate: open_pending_explicit_prompt
implementation_execution_gate: blocked

Implementation planning may now be explicitly prompted. Implementation execution remains blocked.

---

4. Planning Carryovers

The implementation planning phase must carry forward:

• X-1 schema placement;
• X-2 primary ID form;
• X-3 JSONB validation policy;
• X-4 enum implementation strategy;
• X-6 dot_pair_signature shape final polish;
• X-7 canonicalization rule prose ratification;
• X-8 rollback test plan authoring.

5. Next Action

Create an Implementation Planning Package. Still no code, no SQL, no DDL, no migration, no PG mutation.
