Checkpoint — Gap-only Scope Spec + FIX7 Read/Report Pilot Design

Session: PROGRAM_MACRO_CLOSE_TOOL_KIEM_THU_V0_1_PLANNING_LAYER_END_TO_END Date: 2026-06-09 Final status: PROGRAM_MACRO_READY — v0.1 planning/design layer closed end-to-end; routed to one Codex checkpoint; read/report-only MVP greenlight gated only on that seal. Production mutation: NO. No install, no PG/Directus/registry/filesystem mutation, no system_issues write, no tool/schema/runner created, no FIX7 resumed, no filesystem DOT invoked, no IU command invoked, no detector executed, no command run, no denominator collapsed, no Codex-sealed decision reopened, no fresh live read taken. All design synthesized from the sealed 2026-06-09 evidence base.

1. What this session did

Closed the entire v0.1 planning/design layer for Implementation Package DOT (Tool-Kiem-Thu) v0.1 as a single program macro, on top of AUTHORITY_CONTRACT_V0_1_READY_FOR_GPT_REVIEW + BCDGH_SEALED + REUSE_EXTRACTION_MAP_READY_FOR_GPT_REVIEW (PARTIAL_READY). Produced a read/report-only Gap-only Scope Spec (+JSON), a FIX7 read/report pilot design, a no-code MVP plan, a 20-row acceptance matrix, a 7-item future-contracts queue, a compact Codex checkpoint packet, and an action-ready blocker packet; updated the index.

3. Track completion

Track	Subject	Result
1	Input audit / consistency	Done — inputs mutually consistent; one sequencing note (consolidated review); 8 unverified items held out.
2	Gap-only Scope Spec	Done — READY read/report surface; DEFERRED execution surface.
3	Prohibited-overlap wall	Done — 20-item wall (spec §16).
4	FIX7 read/report pilot	Done — 7 Recheck-8 reasons → read-only verdicts; runs nothing.
5	MVP plan (no code)	Done — modules/inputs/outputs/phases/gates/negatives/exit semantics; build blocked until seal.
6	Acceptance test matrix	Done — 20 in-scope + 7 deferred; fail-closed criteria.
7	Future contracts queue	Done — Call Contract keystone + 6 more.
8	Codex checkpoint packet	Done — compact; 5 questions.
9	Action-ready blockers	Done — no engineering omissions; B0 + B1/B2/B3 owner/authority only.
10	Self-verification	Done — §4 below.

4. Track 10 — self-verification (all PASS)

• No mutation — only KB design docs under knowledge/dev/laws/tool-kiem-thu/ were written; no PG/Directus/registry/filesystem/system_issues mutation. ✅
• No tool/schema/runner created — all deliverables are design/plan markdown + one design-summary JSON (explicitly not a runtime schema/manifest). ✅
• No commands invoked — no FS DOT, no IU command, no detector, no canonicalizer, no fresh live read. ✅
• No authority decision reopened — A–J carried verbatim; no sealed wording altered. ✅
• No denominators collapsed — 7 denominators kept separate with provenance throughout; "single DOT number = disguised hardcode" enforced. ✅
• No prohibited overlap introduced — the 5 parallel-authority risks remain NO; the 20-item wall holds. ✅
• Spec is read/report-only — strongest positive verdict = EVIDENCE_PRESENT (is_proof_of_run:false). ✅
• FIX7 pilot runs nothing — checks evidence-presence only; run-half deferred to Call Contract. ✅
• Codex checkpoint packet is compact — 5 questions, no re-investigation required. ✅
• MVP prompt writable later without reopening architecture — MVP plan §2–§12 fixes module/IO/phase/gate design now; only build (post-seal) remains. ✅

5. Verdicts

• Gap-only Scope Spec: READY (read/report surface) / DEFERRED (execution surface).
• FIX7 pilot: sufficient to catch the Article-14 class at read/report level (claim-without-evidence = a read-only test); run-half correctly deferred.
• MVP readiness: build-ready pending B0 (one Codex seal); no engineering blockers.
• Acceptance matrix: 20 in-scope tests fail-closed + 7 deferred.

6. Minimal safe next step (exactly one)

Route reviews/codex-checkpoint-packet-gap-only-spec-and-fix7-pilot-2026-06-09.md to Codex (optionally a GPT pass first). On GAP_ONLY_SPEC_SEALED, the read/report-only MVP build may start (no execution capability). Do not implement, invoke, install, mutate, or create a tool/schema/runner before the seal. The execution surface stays carved out behind B1/B2/B3.
