+## 1. Executive decision
+
+| Q | question | verdict | evidence anchor |
+|---|---|---|---|
+| Q1 | IMP-07 actual implementation status | **closed-as-no-runtime** (policy close; no backend adapter; no FE trigger) | u2 close-trio c.17970 / c.19226 / c.19240; u3 BE grep 1 hit (docstring) + FE grep 0 hits |
+| Q2 | Backlog accuracy for IMP-07 (and dependent IMP-16) | **divergent — correct to `documented:no-runtime` (IMP-07) + `documented:dormant` (IMP-16)** | Backlog L51 / L67 currently both `implemented`; status-vocabulary precedent at L68–L71 (`documented`, `documented (deferred)`) |
+| Q3 | IMP-16-U2 3 deferred items resolution | **all three DORMANT pending reverse-path reactivation** (no runtime substrate to resolve any of the three) | u4 §3 (a/b/c each cite u2 + u3 + IMP-16-U2-WIRING-DESIGN.md L14–16 gate clauses, all NOT CLEARED) |
+| Q4 | Follow-up needs | **1 backlog correction (applied in u7) + 1 doc-sync follow-up (drafted in §6, NOT posted)**; no runtime follow-up needed under current policy | §5 (backlog patch) + §6 (doc-sync banner draft) |
+
+**Final decision**: see §7 below.

+
+## 3. IMP-07 verdict (with evidence)
+
+**Verdict**: `documented:no-runtime` — reverse-path (B-2 Edited HTML → MDX) was closed by user policy decision on 2026-05-15 (c.17970) and re-affirmed by structured close-audit on 2026-05-18 (c.19226 + c.19240). **No backend adapter, no frontend trigger, no `html_to_slide_mdx` port exists in this repository.**
+
+### Evidence chain (compact form — full verbatim in drafts)
+
+1. **Initial close decision** — c.17970 (2026-05-15T18:28:22+09:00):
+   > `<< 해당 기능 필요 없음 >>`
+   > `(*) mdx → html 변환 이후 html 수기 수정된 것은 html에서만 적용.`
+2. **Structured close-audit (v1)** — c.19226 (2026-05-18T08:31:05+09:00). Section 3 enumerates the *absence* of every required runtime surface: SlideCanvas outerHTML capture absent; backend POST absent; `/api/edit | /api/html_to_mdx | /api/save` endpoints absent; glubeot `html_to_slide_mdx` not ported. Section 5 verdict: `"코드 변경 없이 close … '구현 완료'가 아니라 '기능 불필요 / 현 정책상 reverse path 미진행'"`.
+3. **Structured close-audit (v2 restatement)** — c.19240 (2026-05-18T08:41:19+09:00):
+   > `"이 이슈는 코드 변경 없이 정책 판단으로 close했다."`
+4. **Live BE grep** (`src/`, pattern P): 1 hit at `src/phase_z2_verification_utils.py:68` inside the docstring of `extract_text_from_html()`. Function body is a deterministic, pure text extractor (`no I/O, no LLM, no network`) — **not** a reverse-path adapter, **not** an HTML→MDX converter, **not** a pipeline re-entry call site.
+5. **Live FE grep** (`Front/client/src/`, pattern P): 0 hits across populated React/TS tree — true absence, not missing-dir false negative.
+
+### Why not `implemented:partial`
+
+c.19226 §3 enumerates the absence of **every** required runtime surface (frontend, backend, converter, endpoint). `implemented:partial` would imply at least one runtime substrate is present; none is.
+
+### Why not plain `documented` / `documented (deferred)`
+
+IMP-17/18/19/20 use `documented` / `documented (deferred)` to mean "design captured, runtime deferred pending an explicit activation gate (IMP-17 carve-out, IMP-18 gap report, etc.)". IMP-07 is a stronger statement — **closed by explicit policy decision, no runtime, reactivation requires reopening the policy in a separate issue**. The `:no-runtime` suffix encodes that distinction so future readers can tell IMP-07 apart from the IMP-17/18/19/20 `documented` family.
+
+### Reactivation contract (informational, NOT a doc edit)
+
+Per c.19226 §5 and c.19240 closing line, reverse-path reactivation requires reopening IMP-07 policy in a **separate** issue covering: endpoint design, marker coverage, re-entry validation. This audit does NOT reopen that policy.
+
+---
+
+## 4. IMP-16-U2 deferred items resolution (with evidence)
+
+**Source**: `docs/architecture/IMP-16-U2-WIRING-DESIGN.md` lines 69–75 (read-only; this doc is FORBIDDEN to edit in this audit per u1).
+
+**Governing gate** (doc L12–L16): three clauses MUST be cleared before any IMP-16-U2 wiring lands.
+
+| gate clause | required state | observed | gate status |
+|---|---|---|---|
+| `IMP-07 implemented + verified` | runtime adapter in `src/`, verified | Gitea #7 closed as policy / no-runtime (c.17970 / c.19226 §5 / c.19240) | **NOT CLEARED** |
+| Repo grep returns runtime hit in non-test `src/` module | ≥1 non-docstring runtime hit for pattern P | u3 hits=1, **docstring only** at `src/phase_z2_verification_utils.py:68` (pure text extractor) | **NOT CLEARED** |
+| Reverse-path entry emits (a) re-entry MDX + (b) upstream HTML | both as deterministic outputs | c.19226 §3 enumerates absence of every required surface; u3 FE grep hits=0 | **NOT CLEARED** |
+
+All three gate clauses NOT CLEARED → resolution policy from issue body Q3 branches: "If Q1 confirms no-runtime / dormant → reclassify item as dormant pending reverse-path reactivation."
+
+### Per-item resolution
+
+| item | text (verbatim, doc L71–L73) | classification | reason | evidence anchor |
+|---|---|---|---|---|
+| (a) | Exact module path of the IMP-07 reverse-path adapter (TBD by IMP-07). | **DORMANT** | No reverse-path adapter exists in `src/`. The TBD slot stays TBD — not answered with a placeholder path. | u3 §3 (single docstring hit at `src/phase_z2_verification_utils.py:68`); c.19226 §3 absent-surface enumeration |
+| (b) | Step 2 preservation cross-check: per-section variant vs whole-MDX variant. | **DORMANT (gate closed)** | Step 2 surface = `verify_text_preservation(reentry_mdx, upstream_generated_html, area_name=...)` (doc L29). With no emitter producing `reentry_mdx`, the per-section vs whole-MDX choice is unanswerable from runtime evidence. | doc L29; u3 §3; c.19226 §3 (`html_to_slide_mdx` not in repo); c.19226 §5 |
+| (c) | Step 14 invented-text telemetry: per `area_name` vs global. | **DORMANT (gate closed)** | Step 14 surface = `detect_invented_text(reentry_mdx, final_html)` (doc L35). With no FE producer of area-tagged HTML (u3 FE grep hits=0), the granularity question has no runtime substrate. The current Step 14 `run_overflow_check` path is unchanged because no reverse-path re-entry sets `debug.json["pipeline"]["reverse_path_reentry"] = True` (doc L42 schema gate). | doc L35; doc L42; u3 §4 (FE 0-hits); c.19240 closing line |
+
+### Axis disambiguation (why DORMANT, not no-runtime)
+
+IMP-07 is **policy-closed** (active decline). IMP-16's verification helpers are **code-present** in `src/phase_z2_verification_utils.py` (u6 `split_into_sentences`, u8 `verify_text_preservation`, u9 `detect_invented_text` ports). The wiring they would land is **gated by IMP-07** (doc L12–L16). Because the gate is closed, the helpers are runtime-inert — they have no upstream caller. `:dormant` captures "code-shape present, runtime entry-point absent"; `:no-runtime` would imply the helpers themselves are absent (they are not).
+
+---
+
+## 5. Backlog status correction proposal
+
+Target file: `docs/architecture/PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` — line-scoped edit to L51 and L67 status cells only. **Exactly 2 line changes**; surrounding cells (id / title / step / source / priority / scope / guardrail / dependency) byte-for-byte unchanged on both rows. Adjacent rows (L50 IMP-06, L52 IMP-08, L66 IMP-15, L68 IMP-17) untouched.
+
+### L51 — IMP-07: `implemented` → `documented:no-runtime`
+
+```diff
+-| ... | hard link: IMP-02 (A-1 normalize schema 와 reverse path schema 정합 필요) | implemented |
++| ... | hard link: IMP-02 (A-1 normalize schema 와 reverse path schema 정합 필요) | documented:no-runtime |
+```
+
+Justification: §3 verdict + close-trio (c.17970 / c.19226 / c.19240) + BE grep (docstring only) + FE grep (0 hits).
+
+### L67 — IMP-16: `implemented` → `documented:dormant`
+
+```diff
+-| ... | hard link: IMP-07 (B-2 main 활성 시점 의미) | implemented |
++| ... | hard link: IMP-07 (B-2 main 활성 시점 의미) | documented:dormant |
+```
+
+Justification: §4 — all three deferred items DORMANT under the IMP-07 no-runtime gate. The row's own `hard link: IMP-07` declares its meaning is conditioned on IMP-07 activation.
+
+### Status-vocabulary precedent
+
+Existing tokens in the file: `pending` (L45), `implemented` (L46–L66 majority), `documented (deferred)` (L68 IMP-17), `documented` (L69 IMP-18 / L70 IMP-19 / L71 IMP-20). The proposed `documented:<qualifier>` form is a minimal suffix extension of an already-present family — and is **explicitly enumerated by the issue body's Q2**: "propose corrected status (`implemented` / `implemented:partial` / `documented:dormant` / `documented:no-runtime` / etc.)".
+
+---
+
+## 6. Follow-up issue recommendations (drafts, NOT posted)
+
+Auto-posting follow-ups is out-of-scope per u1. The drafts below are recommended text only; this audit does **not** post them.
+
+### Recommended follow-up #1 — doc-sync banner for `IMP-16-U2-WIRING-DESIGN.md`
+
+- **Draft title**: `[DOC-SYNC] IMP-16-U2-WIRING-DESIGN.md — add cross-reference banner to INTEGRATION-AUDIT-02-REPORT.md (IMP-07 closed-as-no-runtime context)`
+- **Scope sketch**:
+  - Add a one-paragraph banner near the top of `IMP-16-U2-WIRING-DESIGN.md` (post-§1 "Status" paragraph) cross-referencing this audit report.
+  - Banner content: IMP-07 was closed-as-no-runtime per Gitea #7 (c.17970 / c.19226 / c.19240). The L12–L16 gate clauses remain unchanged but are currently NOT CLEARED; the 3 deferred items (L71–L73) are DORMANT pending a future reverse-path reactivation issue.
+  - **Do NOT** modify the gate clauses, the per-step wiring contract, or the deferred items themselves — preserve them verbatim as the binding contract for any future IMP-07 reactivation.
+- **Allowed file changes**: `docs/architecture/IMP-16-U2-WIRING-DESIGN.md` (banner add only); optionally a one-line back-link in `INTEGRATION-AUDIT-02-REPORT.md`.
+- **Forbidden**: any change to the doc's gate clauses, per-step contract, or deferred items list; any change to `src/**`, `templates/**`, `tests/**`.
+- **Acceptance**: banner contains explicit cross-link to `INTEGRATION-AUDIT-02-REPORT.md`, cites c.17970 / c.19226 / c.19240, and states the 3 deferred items are DORMANT (not resolved, not closed).
+- **Rationale for separating from this audit**: per u1 scope-lock, `IMP-16-U2-WIRING-DESIGN.md` is a forbidden write surface in INTEGRATION-AUDIT-02 (issue #56). The banner addition is a separate doc-sync axis.
+
+### No runtime follow-up needed under current policy
+
+Reverse-path runtime activation is **out-of-scope under current user policy** (c.17970 / c.19226 §5 / c.19240). A runtime follow-up would require reopening IMP-07 policy in a separate issue — that decision lies with the user, not with this audit. This audit does NOT recommend a runtime follow-up at this time.
+
+### Pre-existing follow-up linkage (informational)
+
+Per the issue body's "Sequence note", the next planned issue #57 ([P5][DORMANT-TRIGGER-GUARD]) will register IMP-17 / IMP-18 / IMP-19 + (per #56 outcome) IMP-16 / IMP-07 + IMP-20 as followup-linked to #55. This audit's verdict feeds #57's dormant-trigger registry input: IMP-07 enters as `documented:no-runtime`; IMP-16 enters as `documented:dormant`.
+
+---
+
+## 7. Final decision
+
+**`NEEDS_DOC_SYNC_FOLLOWUP`**
+
+Rationale: the in-scope reconciliation (backlog L51 + L67 status corrections) is performed in u7. However, `IMP-16-U2-WIRING-DESIGN.md` opens with `**Status**: design-only contract. **No runtime wiring lands in this issue.** All wiring is gated behind IMP-07 reverse-path activation (B-2 main). When IMP-07 lands, this doc becomes the binding contract …` (L3) — written under the original assumption that IMP-07 would eventually land as runtime. With IMP-07 now classified `documented:no-runtime` (policy decline, not deferred-pending-future), this framing is stale without a cross-reference banner pointing readers to the present audit. Because u1 forbids direct edits to that doc, the banner addition must be a separate follow-up issue (drafted in §6, NOT posted by this audit).
+
+Why not `BACKLOG_PATCH_ONLY`: the backlog patch alone leaves `IMP-16-U2-WIRING-DESIGN.md` reading as a future-binding contract without acknowledging the IMP-07 close. A reader landing on that doc would not know to consult this audit.
+
+Why not `NEEDS_RUNTIME_FOLLOWUP`: reverse-path runtime is out-of-scope under current user policy (c.17970 / c.19226 §5 / c.19240); recommending a runtime follow-up would contradict the binding close-decision.
+

+
+## Acceptance Criteria checklist (issue body)
+
+| AC | requirement | status |
+|---|---|---|
+| 1 | No production source code (`src/**`, `templates/**`, `tests/**`) changes | ✅ — u1 forbids; u2–u6 verified empty tracked diff on these surfaces; u7 scoped to BACKLOG.md only |
+| 2 | No direct modification of `IMP-16-U2-WIRING-DESIGN.md` | ✅ — u1 forbids; banner addition deferred to follow-up #1 in §6 |
+| 3 | Each of Q1~Q4 has evidence-backed answer | ✅ — §1 table cites u2/u3/u4 drafts; §3, §4, §5, §6 expand each answer |
+| 4 | Evidence table includes concrete `file:line`, comment IDs, commit SHAs | ✅ — §2 cites `src/phase_z2_verification_utils.py:68`, c.17970 / c.19226 / c.19240, SHA `47f072e`, `BACKLOG.md:51` / `:67`, `IMP-16-U2-WIRING-DESIGN.md:69-75` / `:12-16` |
+| 5 | Final decision ∈ {BACKLOG_PATCH_ONLY, NEEDS_DOC_SYNC_FOLLOWUP, NEEDS_RUNTIME_FOLLOWUP} | ✅ — §7 = `NEEDS_DOC_SYNC_FOLLOWUP` |
+| 6 | Body size budget: each Gitea comment ≤ 8000 chars | ✅ — Stage 3 comments split large evidence into `.orchestrator/drafts/56_*.md` + this report; report body itself is not a comment |
+
+---
+
+## Evidence drafts (RULE-6 evidence-only; NOT staged for commit)
+
+- u1: `.orchestrator/drafts/56_scope_lock.md` — scope binding + forbidden / allowed writes.
+- u2: `.orchestrator/drafts/56_close_evidence.md` — c.17970 / c.19226 / c.19240 verbatim.
+- u3: `.orchestrator/drafts/56_code_grep.md` — `src/` 1 hit (docstring) + `Front/client/src/` 0 hits.
+- u4: `.orchestrator/drafts/56_imp16_deferred.md` — 3 deferred items DORMANT (per-item table).
+- u5: `.orchestrator/drafts/56_backlog_diff.md` — L51 + L67 status-cell diff proposal.
+
+These drafts are evidence-only per RULE 6 and remain untracked. The committed deliverables of INTEGRATION-AUDIT-02 are: (i) this report (`INTEGRATION-AUDIT-02-REPORT.md`), and (ii) the 2 line-scoped status-cell edits applied in u7 (`PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` L51 + L67).
