# u3 — imp07_code_reality_grep (evidence-only, RULE-6, not staged for commit)

**Stage**: Stage 3 / Round #3 — Issue #56 (INTEGRATION-AUDIT-02)
**Unit**: u3 `imp07_code_reality_grep`
**Mode**: audit-only (P4/P4a). No production / template / test edits.
**Date**: 2026-05-20

---

## 1. Binding grep pattern P (Stage 2 verbatim)

```
html_to_slide_mdx|edited_html_to_mdx|reverse_path|reverse-path|reversePath|html-to-mdx
```

Pattern P is the exact union from Stage 2 exit report. No expansion, no shrinkage.

---

## 2. Scope axes (two)

| axis | scope | role in Q1 verdict |
|------|-------|---------------------|
| BE   | `src/`             | backend adapter / pipeline re-entry implementation surface |
| FE   | `Front/client/src/`| edited-HTML payload-path trigger surface |

Both axes are mandated by the issue body's Q1 (read-only inputs: `src/` live code grep + `Front/client/src/` live code grep for HTML→MDX payload path).

---

## 3. Grep results — axis BE (`src/`)

Command (tool-form):
```
Grep(pattern=P, path="src", output_mode="content", -n=true)
```

Raw output:
```
src\phase_z2_verification_utils.py:68:    verification to compare reverse-path HTML against MDX text without
```

- **hits**: 1
- **location**: `src/phase_z2_verification_utils.py:68`
- **classification**: **docstring only**

### Context (lines 64–73)

```python
def extract_text_from_html(html: str) -> list[str]:
    """Return ordered list of visible text fragments from an HTML string.

    Deterministic, pure: no I/O, no LLM, no network. Used by Phase Z
    verification to compare reverse-path HTML against MDX text without
    importing the Phase Q reference-only module.
    """
    parser = _TextExtractor()
    parser.feed(html)
    return parser.texts
```

### Reading
- The hit is line 68 inside the docstring of `extract_text_from_html()` (lines 64–70).
- Function is a **deterministic, pure text extractor** (`no I/O, no LLM, no network`) — a helper for **comparing** an already-existing HTML payload to MDX text.
- The phrase `reverse-path HTML` is a passing reference describing the *kind of HTML* this helper would compare against — **NOT an implementation of a reverse-path adapter** (no HTML→MDX conversion, no pipeline re-entry, no `requests`/HTTP, no Anthropic/AI call).
- This is precisely the "docstring-only" classification recorded in Stage 1 root_cause and Stage 2 evidence block.

---

## 4. Grep results — axis FE (`Front/client/src/`)

Command (tool-form):
```
Grep(pattern=P, path="Front/client/src", output_mode="content", -n=true)
```

Raw output:
```
No matches found
```

- **hits**: 0
- **classification**: **payload-path absent**

### Sanity check — `Front/client/src/` is a real, populated tree
`ls Front/client/src` returns: `App.tsx`, `components/`, `const.ts`, `contexts/`, `data/`, `hooks/`, `index.css`, `lib/`, `main.tsx`, `pages/`, `services/`, `types/`, `utils/`.
→ The 0-hits result is not a "directory missing" false negative; it is a true absence of any reverse-path payload trigger.

### Reading
- No SlideCanvas `outerHTML` capture / POST.
- No `fetch`/`axios` to any reverse-path endpoint.
- No `reverse_path` / `reversePath` / `html-to-mdx` / `html_to_slide_mdx` / `edited_html_to_mdx` symbol referenced anywhere in the frontend bundle.
- Consistent with c.19226 §3 (frontend SlideCanvas outerHTML→backend POST absent) and c.19240 (policy close, no code change).

## 5. Cross-reference to Stage 1 / Stage 2

| claim source | claim | this grep |
|--------------|-------|-----------|
| Stage 1 exit `evidence.reverse_path_grep` | hits=1 at `src/phase_z2_verification_utils.py:68` (docstring) | ✅ exact match (axis BE) |
| Stage 2 u3 test 1 | `src/ grep P: hits=1 at src/phase_z2_verification_utils.py:68 (docstring)` | ✅ PASS |
| Stage 2 u3 test 2 | `Front/client/src/ grep P: hits=0 (payload-path absent)` | ✅ PASS |
| Stage 2 u3 test 3 | `verdict: IMP-07 = closed-as-no-runtime (no backend adapter, no FE trigger)` | ✅ verdict held — see §6 |
| c.19226 §3 (u2 draft) | enumerates absence of SlideCanvas outerHTML capture / backend POST / `/api/edit` / `/api/html_to_mdx` / `/api/save` / `html_to_slide_mdx` | ✅ grep agrees (no FE trigger, no BE endpoint pattern, no glubeot import) |
| c.17970 (u2 draft) | `해당 기능 필요 없음` / `mdx -> html 변환 이후 html 수기 수정된 것은 html에서만 적용` | ✅ consistent with 0 reverse-path runtime in repo |
| c.19240 (u2 draft) | `코드 변경 없이 close` | ✅ consistent (no implementation present) |

Zero contradicting evidence across the trio + u2 close-trio readings + u3 live grep.

## 6. Verdict (u3 contribution to Q1)

**IMP-07 = closed-as-no-runtime.**

- **No backend adapter**: only one grep hit on pattern P in `src/`, and that hit is a docstring describing a *verification helper* — not a reverse-path implementation. No function definition, no HTTP handler, no LLM/AI rewrite, no pipeline re-entry call site.
- **No FE trigger**: 0 hits across the entire React/TS frontend bundle at `Front/client/src/`. No payload-path component, hook, service, or const references the reverse-path namespace.
- The single docstring reference is forward-looking *language* (it describes the kind of HTML that *would* be compared) and does NOT constitute a runtime implementation of the reverse path.

This verdict matches Stage 1 root_cause (`No reverse-path runtime exists in src/ (only one docstring reference at src/phase_z2_verification_utils.py:68)`) and Stage 2 evidence block exactly.

---

## 7. Scope-lock compliance (per u1 draft)

- ✅ No edits to `src/**`, `templates/**`, `tests/**`, or `docs/architecture/IMP-16-U2-WIRING-DESIGN.md` in this round.
- ✅ Only file written: `.orchestrator/drafts/56_code_grep.md` (evidence-only, RULE 6, untracked, not staged for commit).
- ✅ No live Gitea API call; this unit relies on local code state only.
- ✅ Pattern P matches Stage 2 verbatim — no expansion, no shrinkage.
- ✅ Scope-qualified verification (per RULE 4): every claim names its axis (BE = `src/`, FE = `Front/client/src/`), file path, and grep result count.

---

## 8. Downstream contracts

u3 evidence feeds:
- **u4** `imp16_u2_deferred_items_resolution` — three deferred items (a/b/c) all DORMANT, citing this u3 grep + c.19226 enumeration of absent surfaces.
- **u5** `backlog_status_correction_proposal` — L51 IMP-07 cell `implemented → documented:no-runtime` rests on this grep + close-trio.
- **u6** REPORT.md §2 evidence table (cell: code grep) and §3 IMP-07 verdict.

No new follow-up candidates surfaced from u3. Q1 axis remains closed-as-no-runtime; reverse-path reactivation would require IMP-07 policy reopen (out-of-scope per Stage 1).
