IU-0 Pilot Round 1 — G-Pilot-3 Single-Slice Writable Report

Phiên: S191 (2026-05-04) Gate: G-Pilot-3 — single-slice writable pilot Slice: IU-0.§2 trong 07-iu0-index-and-core.md Result: PASS


1. What was done

Patched đúng 1 paragraph trong §2.2 của 07-iu0-index-and-core.md. File rev 1 → rev 2.

Before (old text):

Mở rộng qua APR cấp medium. Dogfooding candidates (OPEN IU-0-γ): `design_doc_section` mới; `proof_note` merge `knowledge_atom` + tag; `review_comment` merge `claim` + category.

After (new text):

Mở rộng qua APR cấp medium. Dogfooding candidates (OPEN IU-0-γ): `design_doc_section` (`proposed_pilot` — G-Pilot-2 tracking active); `proof_note` → merge vào `knowledge_atom` + profile tag; `review_comment` → merge vào `claim` + profile category. Quy tắc mở rộng: mỗi candidate phải justify tại sao không dùng existing seed value + profile extension trước khi đề xuất value mới.

Changes: +pilot status cho design_doc_section, +arrows cho merge notation, +explicit extension policy rule. Không đổi seed table, không đổi §2.1/§2.3.


2. Isolation verification

Section Changed?
Header/status ❌ Identical
§0 Tóm tắt ❌ Identical
Phụ thuộc ❌ Identical
Module map ❌ Identical
Guardrails GR-1..10 ❌ Identical
5 Quyết định ❌ Identical
§1 Mục đích ❌ Identical
§2.1 Nguyên tắc ❌ Identical
§2.2 unit_kind seed table ❌ Identical
§2.2 dogfooding paragraph Changed (as intended)
§2.3 Anti-patterns ❌ Identical
§3 UMC ❌ Identical
§4 Profile/Capability ❌ Identical
Footer ❌ Identical

Isolation: PASS — chỉ 1 paragraph trong §2.2 thay đổi.


3. Metrics

Metric Value
Chars read (§2 only) ~1900
Chars read (full file alternative) ~8100
Token savings ~77% (475 vs 2025 tokens)
Chars edited (old → new) ~180 → ~330 (+150 chars)
Tool calls 3 (read + patch + verify)
Turn count ~2 turns
Target: savings ≥50% ✅ 77%
Target: cycle ≤5 turns ✅ 2 turns

4. MUP impact

Không thay đổi MUP 15 elements. Patch chỉ refine wording + thêm policy rule trong §2.2 — không đụng UMC elements, profile fields, hoặc birth gate threshold.

design_doc_section status updated từ "mới" → "proposed_pilot — G-Pilot-2 tracking active". Consistent với G-Pilot-2 tracking report.


5. Rollback note

File: 07-iu0-index-and-core.md rev 1 → rev 2. Rollback = patch back old text (exact old string available in §1 of this report).


6. Compliance

Check Status
Chỉ sửa §2
Không đổi UMC/Profile inheritance
Không tạo schema family mới
Không mở P44-6
Không sửa 07b/07c/P38-XC
Không DDL/code/migration
Không IU table/Qdrant/outbox
Không mutate legacy vector
Vocab registration thật? Không — proposed_pilot status only

7. Gate verdict

G-Pilot-3: PASS. Single-slice writable pilot thành công:

  • Workflow đọc → extract → patch → verify hoạt động.
  • Token savings 77% (>50% target).
  • Edit cycle 2 turns (<5 target).
  • Isolation verified — chỉ §2.2 thay đổi.
  • Không side-effect.

Đề xuất next step: Thử slice P38-XC an toàn (P38-XC.§4) theo chỉ đạo GPT.
