# INTEGRATION-AUDIT-01 -- Phase Z closed-issue cumulative consistency review

## Section 1. Audit anchor

**Anchor (cited verbatim per Stage 1 exit report)** :
> This audit verifies pipeline contracts. It does not optimize any single MDX sample.

**Scope** : 22 closed Gitea issues `#2-#18 + #45-#49` on `Kyeongmin/C.E.L_Slide_test2` against the 22-step Phase Z pipeline (`docs/architecture/PHASE-Z-PIPELINE-OVERVIEW.md`, Steps 1-22 plus Step 0 precondition).

**Mode** : audit-only -- no source code changes. Report-only file changes under `docs/architecture/INTEGRATION-AUDIT-*.md` and one row in `docs/architecture/PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` (u7).

**Parent / child relationship** : Gitea `#15` = parent (IMP-15 Step 14 visual_check reinforcement). Execution children = `#45 / #46 / #47 / #48 / #49`. Locked child SHAs (Stage 1 exit report) :
- `#45` -> `e9b3d2e` (execution-1, image_aspect_mismatch detection)
- `#46` -> `2827622` (execution-2, table_self_overflow detection; commit message label says `IMP-16` but the closed Gitea issue is `#46`; flagged in Section 3)
- `#47` -> `535c484` (execution-3, classifier consumes image+table events)
- `#48` -> `614c533` (execution-4, debug.json event surfacing + spec taxonomy)
- `#49` -> no new SHA (verification-only per `#15` body; re-uses `614c533` evidence)

**Close timestamp anomaly** (Stage 1 lock, recorded; NOT reopened) :
- `#15` closed `2026-05-19T02:35:05+09:00`
- `#45 / #46 / #47 / #48` all closed BEFORE `#15` (correct ordering)
- `#49` closed `2026-05-19T02:49:56+09:00` -- about 15 minutes AFTER `#15` close (anomaly)
- Disposition : record-only in Section 3 / Section 6 finding column; no remediation row in backlog beyond the existing audit completion row (u7).

**Excluded (open / not in audit)** : `#1, #19, #20, #21, #22, #23, #24, #25, #26, #27, #28, #38, #39, #40, #41, #42, #43, #44`.

**Sample budget** : `samples/mdx_batch/03.mdx` (smoke) plus `samples/mdx_batch/04.mdx` (details + images). Pipeline runs captured in Section 7.

---

## Section 2. Baseline pytest

**Method** : `pytest -q tests` is the project regression suite. The audit captures it twice -- once before any u5 / u6 / u7 edits, once after Section 7 / 8 grep + render evidence is collected. Equality of both runs proves the audit-only work surface (`docs/architecture/INTEGRATION-AUDIT-*.md` + backlog row in u7) did not perturb production code.

**Command** : `pytest -q tests` (working dir = repo root `D:\ad-hoc\kei\design_agent\`).

**Pytest BEFORE audit u5 edits (audit date 2026-05-19)** :
- Result : `303 passed in 40.80s`
- Last 5 progress dots aggregated to `[100%]` then `Running teardown with pytest sessionfinish...` -- expected suite teardown banner.

**Pytest AFTER audit u5 edits (post §7 / §8 evidence collection, same audit date)** :
- Result : `303 passed in 40.54s`
- 303 == 303 ; 0 new failures, 0 skipped, 0 errored. Test count parity proves no test discovery side-effect from new audit docs.

**Verdict** : OK. Audit-only edits under `docs/architecture/INTEGRATION-AUDIT-*.md` introduce no regression. Baseline stable across u5 assembly.

---

## Section 3. Axis 1 -- Scope myopia (22 issues x adjacent-contract cross-reference)

**Method** : per closed issue, list (a) its own scope as declared in body / backlog row / closing commits, (b) adjacent pipeline contracts the change could have leaked into, (c) downstream consumers of its outputs, (d) finding label `OK` / `Warning` / `Blocker`. Each row cites `src/`, `tests/`, `docs/`, or `templates/` paths.

**De-dup convention** : `#15` is treated as the *integration parent*; the actual code/test changes are owned by execution children `#45-#49`. `#15` row records integration glue only (parent close evidence + cross-child reconciliation). No change is double-counted across parent + child.

**Pipeline step shorthand (per `PHASE-Z-PIPELINE-OVERVIEW.md`, full 22-step list)** :
- Step 0 precondition / 1 MDX upload / 2 normalize / 3 content_object / 4 internal composition planning / 5 V4 evidence / 6 composition planning / 7 layout vocabulary / 8 zone+region ratio / 9 region-level frame/display / 10 frame contract / 11 region-to-slot mapping / 12 slot payload / 13 render / 14 visual_check / 15 fit_classification / 16 router / 17 action / 18 failure_classify / 19 next_action / 20 slide_status / 21 debug.json / 22 user UI.

### Section 3 finding summary

- **OK** rows : `#2 #3 #4 #5 #7 #8 #9 #10 #11 #13 #14 #16 #17 #18 #45 #47 #48` (17)
- **Warning** rows : `#6` (wide override blast radius, contained by tests); `#12` (multi-donor + cascade, contained by 5 test modules); `#15` (close-timestamp anomaly via `#49`); `#46` (commit-message label drift only, SHA correct); `#49` (close-timestamp anomaly, verification-only) -- 5 rows
- **Blocker** rows : 0
- **Total** : 17 OK + 5 Warning + 0 Blocker = 22 rows (matches 22 closed issues under audit).
- **De-dup audit** : `#15` row carries no code attribution; all code/test work attributed to `#45-#48` (and `#49` = verification-only). No double-count.

### Section 3 cross-issue scope-myopia adjacency check

Adjacent-contract pairs flagged for Section 5 Axis 3 re-verification (producer to consumer continuity) :
- `#2` Step 2 normalize output -> `#3` Step 3 content_object input
- `#3` content_object schema -> `#8` sub_sections schema extension
- `#4` catalog expansion -> `#5` V4 fallback candidate pool dedup
- `#4` catalog expansion -> `#10`-`#11` `min_height_px` exposure
- `#9` layout vocabulary -> `#12` retry zone-ratio donor selection
- `#9` layout vocabulary -> `#11` Step 9 min_height v4-all-judgments test
- `#45 + #46` Step 14 events -> `#47` Step 15 classifier -> Step 16 router
- `#48` debug.json event surfacing -> `#21` (Step 21 debug consumer; open, excluded)
- `#17` AI carve-out -> `#5 + #4` activation 3-cond AND gate (gated, not active)

Axis 3 (Section 5) will verify each pair has agreeing producer-line / consumer-line on the live code.

## Section 4. Axis 2 -- 22 issues x 22 steps pipeline matrix

**Split rationale** : at u1 completion the combined REPORT was 21,070 bytes / 136 lines -- over the 10 KB readability threshold defined in the Stage 2 plan. Per the split rule (`combined REPORT >= 10 KB grid moves to MATRIX.md + back-pointer`), the 22 x 22 grid lives in the companion file :

- `docs/architecture/INTEGRATION-AUDIT-01-MATRIX.md`

**What MATRIX.md contains** :
- Step 0 precondition NOTE (NOT a grid column) -- 5 issues (`#4 #11 #13 #14 #18`) recorded with scope summary + evidence path.
- 22 x 22 grid (Step 1 through Step 22 columns x 22 issue rows). Cell legend : `P` = primary touch, `A` = adjacent contract, `.` = no touch. ASCII-only.
- Row footer (touched-step count) and column footer (touching-issue count + `H` HOTSPOT marker for col total >= 4).
- HOTSPOT enumeration (9 steps : `S2 S9 S13 S14 S15 S16 S17 S21 S22`).
- Cross-check against the 9 adjacent-contract pairs flagged in Section 3.
- Empty / low-touch column notes (Step 4 and Step 11 are `missing` per PHASE-Z-PIPELINE-OVERVIEW -- 0 touches expected).
- Parent/child de-dup sum check : `#15` row carries 3 adjacencies and zero `P` cells ; only `#45 #46 #47 #48` carry the 4 primary cells for the `#15` family ; `#49` is verification-only with all-`A`.

**Section 4 summary (for readers staying in REPORT)** :
- 9 hotspot steps (col total >= 4) : Step 2 (4), Step 9 (6), Step 13 (5), Step 14 (9 highest), Step 15 (6), Step 16 (4), Step 17 (4), Step 21 (8), Step 22 (7).
- 2 empty columns : Step 4 + Step 11. Consistent with master pipeline `missing` status -- no audit gap.
- Total grid cells filled = 77 (row sum = col sum, cross-checked).
- Top row-total issues : `#6` (7), `#5` (6), `#8` (6), `#12` (6) -- the 2 `Warning` rows (`#6 #12`) sit at the top, consistent with Section 3 wide-blast-radius finding.

---

## Section 5. Axis 3 -- Cross-issue conflict per invariant category

**Method** : 6 invariant categories listed in the issue body. Per category, identify producer file:line, consumer file:line, the named state key / contract, the closed issues that touch it, agree-or-conflict verdict, plus grep evidence path. Categories are evaluated against the live tracked code at audit time, not against historical snapshots.

### 5.1 Invariant category roster (from issue body)

| # | category | issue-body wording |
|---|---|---|
| C1 | `debug.json` schema | phase_z2 debug payload paths; no conflicting key type / semantics |
| C2 | `visual_check_passed` | `src/phase_z2_pipeline.py` Step 14 / 17; set-site <-> read-site agree |
| C3 | `fit_classification` / router | `src/phase_z2_mapper.py` + consumers; labels consistent producer -> consumer (charter mis-cite; live producer = `src/phase_z2_classifier.py` -- see §10 F-1) |
| C4 | Step 14 / 17 / 21 interactions | expected state values stay aligned across the trio |
| C5 | Phase R vs Phase Z boundary | no R regression, Z additions don't leak into R |

### 5.4 Axis 3 summary

- 6 invariant categories evaluated. All AGREE for the closed-issue audit scope.
- 2 surface notes recorded as Section 10 follow-up candidates :
  - **F-1** : issue body cites `src/phase_z2_mapper.py` for invariant C3 (`fit_classification`), but the live producer is `src/phase_z2_classifier.py`. Record-keeping correction needed in any future audit charter, not a code conflict. RESOLVED via IMP-53 (2026-05-19)
  - **F-2** : 2 untracked family templates exist on disk without `frame_contracts.yaml` entries; IMP-18 doc cites "families/*.html (13)" forward-looking. Tracked baseline (11 / 11) is consistent. Contract drift is *not* present for any closed issue; the WIP delta belongs to open work. RESOLVED via #52 option (c) (2026-05-19) -- WIP allowlist captured in `templates/phase_z2/families/_WIP_FILES.md`; tracked + contracted baseline unchanged at 11/11; promote / remove gated on #42.
- 1 documented partial recorded :
  - Step 21 `_write_step_artifact` at `pipeline.py:4772` carries `step_status="partial"` with note `region marker partial 미주입 -- Step 21 ⚠ partial`. This is *self-honest acknowledged* per `feedback_artifact_status_naming`; no cross-issue conflict.
- Phase R' <-> Phase Z boundary clean both directions for the 22 closed issues.
- 0 Blocker findings in Axis 3.

### 5.5 Live-grep re-verification stamp (audit date 2026-05-19)

| C6 frame_contracts entries | `grep -cE "^[a-z_]+:$" templates/phase_z2/catalog/frame_contracts.yaml` | 11 | MATCH (Section 5.2 C6 row says "= 11") |

No discrepancy between Section 5.2 grep evidence and live code. Re-verification re-confirms u3 Axis 3 conclusion : 6 invariant categories all AGREE; 2 record-keeping follow-up candidates (F-1, F-2); 1 documented partial (Step 21); 0 Blocker findings.

## Section 6. Axis 4 -- Backlog vs code reality status matrix

**Method** : per closed issue, compare (a) `docs/architecture/PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` status column at audit time (live read 2026-05-19), (b) live src/ + templates/ + tests/ + docs/ evidence (grep hits + file existence), (c) the audit-allowed status enum `implemented | documented (deferred) | pending`, (d) mismatch flag.

**Per issue-body rule set** :
- `implemented` -> live grep on `src/**` MUST show wired call site(s); not just a single declaration with no consumer.
- `documented (deferred)` -> live grep on `src/**` MUST NOT show a production code path that assumes the feature is active (carve-out only).
- `pending` -> live grep on `src/**` MUST NOT show wired implementation (or evidence shows incomplete).
- `pending -> documented` flip -> reason cited in backlog row must match what `src/**` actually contains.

### 6.1 Backlog status legend (live read on audit date)

| backlog status | IMP rows under audit | meaning |
|---|---|---|
| `documented` | `IMP-18` (1 row) | doc-only carve-out, no production path |
| `pending` | `IMP-02` through `IMP-17` (16 rows) | backlog status column has NOT been flipped, despite Gitea issue being closed |
| (no backlog row) | `#45 / #46 / #47 / #48 / #49` (5 rows) | execution children of `#15`; backlog tracks the parent `IMP-15` only -- and `IMP-15` is itself still marked `pending` in §2 row |

**Headline Axis 4 finding** : `PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` status column is **stale across the entire closed-issue audit scope** -- 16 of 22 audited issues are flagged `BACKLOG_STALE` (backlog `pending` vs Gitea closed + live code wired); additionally 5 of 22 carry `NO_BACKLOG_ROW` for the `#15` execution children (`#45-#49`), and only 1 of 22 (`#18`) is `AGREE`. Reconciliation: 16 `BACKLOG_STALE` + 5 `NO_BACKLOG_ROW` + 1 `AGREE` = 22 (matches Section 6.3 summary and the 15+1=16 flip plan in §6.3 follow-up reference). This is documentation drift, not a code-side contract conflict; recorded as Section 10 follow-up candidate `F-3`.

### 6.2 Axis 4 -- 22 row backlog vs code reality matrix

Status meaning (audit verdict column) :
- `implemented_live` = backlog should be flipped to `implemented`; live src/ wiring proves it (grep evidence below).
- `documented_live` = backlog `documented` matches code reality (doc-only carve-out; no prod path).
- `child_of_parent` = no backlog row by design (execution child of parent IMP-15); status tracked via parent row.

Mismatch flag :
- `BACKLOG_STALE` = backlog says `pending` but code is wired live. Documentation drift only; no code conflict.
- `AGREE` = backlog status matches live code reality.
- `NO_BACKLOG_ROW` = execution child, child not represented in backlog; not an error, but parent `IMP-15` row is itself stale.

### 6.3 Axis 4 summary

- **BACKLOG_STALE** rows : `#2 #3 #4 #5 #6 #7 #8 #9 #10 #11 #12 #13 #14 #15 #16 #17` = 16 rows (status column reads `pending` but live code is wired; for `#17` the right target status is `documented (deferred)` while for the other 15 it is `implemented`).
- **AGREE** rows : `#18` = 1 row (the only issue whose backlog status truthfully reflects code reality).
- **NO_BACKLOG_ROW** rows : `#45 #46 #47 #48 #49` = 5 rows (execution children, by-design no backlog row; parent `IMP-15` row exists but is itself BACKLOG_STALE).
- **Total** : 16 + 1 + 5 = 22 rows (matches 22 closed issues under audit).
- **Implementation-vs-documented split** (audit verdict, ignoring backlog wording) :
  - `implemented_live` (runtime path wired) : `#2 #3 #4 #5 #6 #7 #8 #9 #10 #11 #12 #13 #14 #15(via children) #16` = 15 rows
  - `documented_live` (doc-only / design-only carve-out, no runtime path) : `#17 #18` = 2 rows
  - `child_of_parent` (no backlog row, attribution via parent) : `#45-#49` = 5 rows
- **0 Blocker findings in Axis 4.** No closed issue is `pending` *and* unimplemented; the only mismatches are documentation drift in the backlog status column.
- **Cross-axis consistency** :
  - Axis 3 C6 frame count `11 tracked / 11 contract entries / 13 on disk (2 WIP)` matches the IMP-04 evidence in Axis 4 row 3 (BACKLOG_STALE but live code present).
  - Axis 3 C5 boundary (Phase R' <-> Phase Z) clean both ways re-confirms `#17 #18` as documented_live (no R' leak).
  - Axis 1 (Section 3) `Warning` rows `#6 #12 #15 #46 #49` are all still `implemented_live` in Axis 4 -- the warnings are about *blast radius* and *administrative drift*, not implementation absence.
- **Follow-up candidate F-3** (Section 10) : `PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md` status column needs a sweep to flip 15 rows `pending` -> `implemented`, 1 row `pending` -> `documented (deferred)` for `IMP-17`, and either add child-row stubs for `#45-#49` or add a footnote on the `IMP-15` row pointing at the 5 execution children. This is a single-file documentation-only edit; orthogonal to source-code Stage 3 work; safe under audit-only scope (deferred to a separate follow-up issue, NOT this audit's u7 backlog row).

## Section 7. Representative pipeline runs

**Method** : run the Phase Z runtime entry (`python -m src.phase_z2_pipeline <mdx_path> <run_id>`) on the two locked samples (`samples/mdx_batch/03.mdx` smoke + `samples/mdx_batch/04.mdx` details+images). Per run capture (from `data/runs/<run_id>/phase_z2/debug.json`) : top-level keys, `slide_status.visual_check_passed`, `slide_status.overall`, zone count, per-zone frame template + slot keys + slot key count, `slide_status.visual_fail_reasons`, `slide_status.filtered_section_reasons`, `selection_paths`, `image_events` / `table_events` count. Compare invariants across both runs.

**Audit date** : 2026-05-19. Both runs are fresh on this audit pass (run_ids `audit50_run_03_smoke` + `audit50_run_04_details`).

### 7.3 Cross-run invariants

| invariant | run #1 (03.mdx) | run #2 (04.mdx) | verdict |
|---|---|---|---|
| debug.json top-level key set | 17 keys (above) | identical 17 keys | AGREE -- Step 21 schema stable across both runs (Axis 3 C1) |
| `slide_status` schema keys | 19 keys (`visual_check_passed`, `full_mdx_coverage`, `rendered`, `overall`, `visual_fail_reasons`, `filtered_section_ids`, `filtered_section_reasons`, `aligned_section_ids`, `covered_section_ids`, `adapter_needed_count`, `adapter_needed_units`, `content_truncated_count`, `content_truncated_units`, `fallback_selection_count`, `fallback_selections`, `fallback_used`, `selection_path`, `selection_paths`, `note`) | identical 19 keys | AGREE -- slide_status surface stable (Axis 3 C2 + C4) |
| `fit_classification` shape | `{visual_check_passed, classifications, summary, categories_seen, ...}` -- matches Axis 3 C3 row | identical shape | AGREE -- classifier output schema invariant |
| `visual_check_passed` semantic | `True` AND `classifications=[]` -> overall `PASS` | `True` AND `classifications=[]` AND `full_mdx_coverage=False` -> overall `PARTIAL_COVERAGE` | AGREE -- visual side passing under both runs; `PARTIAL_COVERAGE` is composition-planner side (upstream of Step 14), so visual_check_passed does NOT contradict overall status (Axis 3 C2 verdict re-confirmed) |
| zone count vs layout preset | `horizontal-2` -> 2 zones (top + bottom) | `single` -> 1 zone (primary) | AGREE -- preset-to-zone arity matches IMP-09 B-4 vocabulary (Axis 1 row 8) |
| frame contract resolution | both zones resolved to a contract id (rank_1 path) | only 1 of 4 selection paths resolved (3 `chain_exhausted` / `no_v4_candidate`) | DIFF EXPECTED -- 04.mdx exhibits v4 candidate gap; this is the composition-planner maturity gap (not in any closed-issue scope). Not a contract conflict. |
| `image_events` / `table_events` arity | both = 0 | both = 0 | AGREE -- neither sample triggers Step 14 image/table self-overflow; `#45` `image_aspect_mismatch` and `#46` `table_self_overflow` event-arrays exist in the schema and are *correctly empty* when no overflow is detected |
| router action triggered | `None` | `None` | AGREE -- Step 16 router is dormant when classifications=[] (Axis 3 C3 verdict re-confirmed; `#12` retry cascade not exercised by these samples) |
| pipeline final banner | `PASS` (full MDX coverage + visual OK) | `PARTIAL_COVERAGE` (visual OK + composition-planner filter) | self-honest status naming per [[feedback_artifact_status_naming]] |

### 7.4 Run-level findings

- Both runs pass the visual_check axis (Axis 3 C2 contract). `visual_check_passed=True` agrees between `fit_classification` and `slide_status` mirror in both runs.
- 04.mdx `PARTIAL_COVERAGE` is a composition-planner side filter (3 sections drop to `chain_exhausted` / `no_v4_candidate` before reaching Step 14). This is NOT an audit Blocker because (a) no closed issue under audit targets composition-planner coverage, (b) the status field is self-honestly named `PARTIAL_COVERAGE` rather than misnamed `PASS` (matches [[feedback_artifact_status_naming]]).
- Step 21 `debug.json` writer surfaces a stable 17-key top-level surface across both runs; Axis 3 C1 invariant re-confirmed at runtime.
- Zero Blocker findings in Section 7.

## Section 8. Anti-hardcoding grep checklist

**Method** : run the 6 anti-hardcoding patterns enumerated in the Issue #50 body. For each, capture the live hit set, classify hits (Phase Z scope vs. legacy Phase R'/Q out-of-scope vs. docstring/comment vs. test fixture), then return a verdict. Raw output preserved at `D:\ad-hoc\kei\design_agent\.orchestrator\tmp\50_grep_checklist_raw.txt` (evidence-only, not staged for commit per Stage 3 directive).

**Audit date** : 2026-05-19. Searched against tracked source on this date.

### 8.1 Checklist

| # | pattern (issue body) | expected | live hit count (src/) | hit classification | verdict |
|---|---|---|---|---|---|
| G1 | `grep -E 'if .* == ["'\\''].*\.mdx' src/` | 0 hits | 0 | none | PASS |
| G2 | `grep -E 'OVERRIDES\s*=\s*\{' src/` | each match sample-agnostic | 0 | none | PASS (vacuously sample-agnostic) |
| G3 | `grep -E '재구성\|건설산업 DX\|BIM' src/` -- sample text leak | 0 hits | 31 source hits across 14 `.py` files (binary `.pyc` matches ignored) | (a) 20 hits in legacy Phase R'/Q files (`block_assembler_b2.py` 1, `block_matcher_tfidf.py` 1, `block_reference.py` 3, `content_editor.py` 3, `design_director.py` 2, `design_tokens.py` 1, `fit_verifier.py` 1, `frame_extractor.py` 1, `kei_client.py` 4, `pipeline.py` 3) -- pre-Phase-Z; not in audit window; (b) 11 hits in Phase Z files (`phase_z2_content_extractor.py` 7 -- all inside `if __name__ == "__main__"` self-test data blocks at lines 466/493/511/556/565/573/591; `phase_z2_failure_router.py:123` 1 -- internal taxonomy string `"topology 부터 재구성. frame_reselect 는 그 다음 단계"`; `phase_z2_mapper.py:519/529` 2 -- docstring examples; `phase_z2_retry.py:59` 1 -- docstring). Per-file count sum = 20 + 11 = 31, matching the live total. | PASS for the audit scope -- **0 closed-issue (#2-#18 + #45-#49)** introduces new sample-specific hardcoded BIM/재구성/건설산업 string literals into runtime code paths. All 11 Phase Z hits are docstring/taxonomy/self-test fixtures, none injected into runtime contracts. Legacy 20 hits are out of audit window. Recorded as Section 10 follow-up candidate `F-4` for future cleanup (doc-only, optional). |
| G4 | `grep -E 'height\s*=\s*720\|aspect\s*=\s*0\.5' src/` -- magic literal pinning | 0 hits | 0 | none | PASS |
| G5 | sample paths come from CLI args / config, not hardcoded | sample-agnostic | 4 occurrences across 2 files (`src/block_assembler.py:1390/1393` + `src/image_utils.py:62/65`) | all 4 hits use `samples/mdx_batch` as one of several **generic asset search directories** alongside `samples/images` (image asset discovery fallback). The directory is treated as a discovery namespace, not as a path to a specific MDX file. CLI entry (`src/phase_z2_pipeline.py:4861`) takes `mdx_path` as positional arg -- no hardcoded MDX path on the runtime entry. | PASS -- sample-agnostic asset discovery default; not a per-sample pin. |
| G6 | `tests/` : sample-specific fixtures only under `tests/fixtures/`, not in production pipeline | fixtures isolated | `tests/fixtures/` directory does not exist; closest hits = `tests/phase_z2/test_pz2_vu_integration.py:6, 82` referencing `samples/mdx_batch/02.mdx` as smoke-coverage MDX | the references in `test_pz2_vu_integration.py` are inside a verification-utility integration test (`#16` IMP-16 scope). The test file is named with the test prefix and lives in `tests/phase_z2/`, so pytest discovery treats it as a test, not as a production module. No production pipeline file imports a sample MDX path literal. | PASS WITH NOTE -- no `tests/fixtures/` directory exists today; the existing integration tests already keep sample references inside `tests/phase_z2/test_*.py`, which discharges the spirit of the rule. Optional follow-up: formalize a `tests/fixtures/` directory if sample inventory grows. Recorded as Section 10 follow-up candidate `F-5` (low priority, doc-only). |

### 8.2 Anti-hardcoding verdict

- 4 patterns PASS cleanly with 0 hits (G1, G2, G4) and 1 PASS with sample-agnostic hits (G5).
- 1 pattern PASS-for-audit-scope with classification (G3) : 11 Phase Z hits are all docstrings/taxonomy/self-test fixtures; 20 legacy hits are out of the 22-closed-issue audit window. Per-file counts sum to 31, matching the live grep total. No closed issue introduces new hardcoded sample text into a runtime code path.
- 1 pattern PASS WITH NOTE (G6) : `tests/fixtures/` directory not yet established; existing integration test references stay inside `tests/phase_z2/`. Already aligned with the spirit of the rule.
- **0 Blocker findings in Section 8.**
- Cross-axis : the F-4 / F-5 follow-up candidates are doc-only optional cleanup; they do not alter any closed-issue contract.

---

## Section 9. Final decision

**Decision** : **CONDITIONAL GO for #19**.

### 9.1 Summary across all 4 audit axes + supporting sections

| section | axis | Blocker | Warning | OK | follow-up candidates |
|---|---|---|---|---|---|
| §3 | Axis 1 -- scope myopia | 0 | 5 (`#6 #12 #15 #46 #49`) | 17 | none Blocker; warnings are blast-radius + administrative drift |
| §4 + MATRIX.md | Axis 2 -- 22 x 22 pipeline matrix | 0 | (9 hotspot steps, 2 expected-empty cols) | 22 issues mapped | none Blocker; hotspots match expected Step 14 / 21 attention |
| §5 | Axis 3 -- cross-issue conflict (6 invariants) | 0 | 0 | 6 categories AGREE | F-1 (body cites mapper.py; live producer is classifier.py for `fit_classification`); F-2 (13 family templates on disk vs. 11 tracked / contracted -- 2 WIP outside any closed issue) |
| §6 | Axis 4 -- backlog vs code reality | 0 | -- | 1 AGREE, 16 BACKLOG_STALE (doc drift), 5 NO_BACKLOG_ROW (by design for `#45-#49`) | F-3 (backlog status sweep : flip 15 rows `pending` -> `implemented`, 1 row `pending` -> `documented (deferred)` for IMP-17, footnote `IMP-15` row with 5 children) |
| §7 | representative runs (03.mdx + 04.mdx) | 0 | -- | both runs visual_check_passed = True; debug.json schema stable; 04.mdx PARTIAL_COVERAGE is composition-planner side (no audit-window contract conflict) | none new |
| §8 | grep checklist (6 patterns from issue body) | 0 | -- | G1/G2/G4/G5 PASS; G3/G6 PASS WITH NOTE | F-4 (legacy Phase R'/Q BIM literals -- optional cleanup); F-5 (formalize `tests/fixtures/` -- optional) |
| §2 | baseline pytest | -- | -- | 303 passed BEFORE + 303 passed AFTER audit | none |

### 9.2 Blocker tally

- **0 Blocker** findings across all four axes and all supporting sections.
- 5 Warning rows in §3 are about blast radius (`#6 #12`), administrative commit-label drift (`#46`), and parent/child close-timestamp anomaly (`#15 #49`). None of them indicate broken code contracts.
- All BACKLOG_STALE rows in §6 are documentation drift, not implementation absence. Live grep on `src/**` confirms each closed issue is wired (or carved-out as designed for `#17 #18`).
- 5 follow-up candidates (F-1 .. F-5) are all doc-only. None require source code changes.

### 9.3 Why CONDITIONAL GO, not unconditional GO

Audit found zero Blocker, but the conditions for upgrading to unconditional GO are not met because:

1. **F-3 (backlog sweep)** is the largest doc-drift surface (16 of 22 audited rows mislabeled). Issue #19 will read the backlog when scoping next-step coverage; running #19 against a stale backlog risks a planner who treats already-implemented features as still pending. The F-3 follow-up should be filed and merged before -- or at minimum in parallel with -- #19 Stage 2 planning.
2. **F-2 (family template count drift)** matters if #19 touches the catalog / `frame_contracts.yaml` (likely). The audit confirms 11 tracked entries are consistent today, but #19 should reconcile the 2 WIP files (`app_sw_package_vs_solution.html`, `pre_construction_model_info_stacked.html`) before adding any new family templates.
3. **F-1 (record-keeping for invariant C3 producer file path)** -- a small but real mismatch between the issue body wording (`src/phase_z2_mapper.py`) and the live producer (`src/phase_z2_classifier.py`). Should be fixed in the audit charter / spec doc before the next integration audit so future audits do not repeat the same drift check.

F-4 / F-5 are optional and do not gate #19.

### 9.4 Conditions to satisfy for #19 progression

- File F-1 / F-2 / F-3 as Section 10 follow-up issues (text-only drafts produced in u6).
- F-3 backlog sweep should land before #19 Stage 2 (so #19 plans against accurate status).
- F-2 family template reconciliation should land before #19 introduces new family templates (whichever comes first).
- F-1 is a one-line spec-doc edit, can land any time before the next INTEGRATION-AUDIT issue is opened.

### 9.5 Decision sentence

> **Issue #19 is approved for entry under CONDITIONAL GO**, with the explicit dependency that follow-up F-3 (backlog status sweep) must land before #19 Stage 2 planning consumes the backlog, and F-2 (family template reconciliation) must land before any #19 work that extends the catalog. No production source code change is required from this audit. Pytest baseline stable (303 passed BEFORE + AFTER).

---

## Section 10. Follow-up issue drafts (text-only, not auto-posted)

**Scope rule (Stage 2 u6 contract)** : per-draft fields = `title` + `source_axis` (1-4) + `scope` (what files / what change) + `evidence_link` (REPORT section that produced the finding). **No Gitea post.** Final disposition of each candidate is the orchestrator / human triage decision after #50 closes; this REPORT only records the audit-side text.

Five candidates were produced by Axes 1-4. F-3 + F-2 + F-1 are blocking conditions for upgrading §9 CONDITIONAL GO -> unconditional GO for #19; F-4 + F-5 are optional housekeeping. None require source-code changes inside this audit.

### 10.1 F-1 -- audit charter record-keeping : invariant C3 producer file path -- RESOLVED via IMP-53 (2026-05-19)

- **title** : `[AUDIT-CHARTER-FIX] invariant C3 (fit_classification) producer cited as src/phase_z2_mapper.py; live producer is src/phase_z2_classifier.py`
- **source_axis** : Axis 3 (cross-issue conflict, invariant category C3) -- recorded in §5.2 C3 row + §5.4 follow-up bullet F-1.
- **scope** :
  - one-line fix in any future INTEGRATION-AUDIT-* issue body or in `docs/architecture/PHASE-Z-PIPELINE-OVERVIEW.md` if it cites the wrong file for `fit_classification` producer.
  - replace text `src/phase_z2_mapper.py` -> `src/phase_z2_classifier.py` *only in the context of `fit_classification` invariant* (mapper.py legitimately owns slot payload and registries, so do not blanket-rename).
  - update audit charter template (if one exists) so the next integration audit does not repeat the drift check.
- **scope-lock** : **doc-only**, zero `src/**` / `templates/**` / `tests/**` edits.
- **evidence_link** :
  - REPORT §5.2 row C3 (issue body wording vs. live producer).
  - REPORT §5.4 follow-up bullet F-1.
  - Live producer site : `src/phase_z2_classifier.py:495-497` (return dict with `visual_check_passed`, `classifications`, `summary`, `categories_seen`, `unclassified_signals`, `placement_diagnostics`).
- **priority / gating** : low priority on its own; required for charter cleanliness; **not** a blocker for #19 Stage 2.

### 10.2 F-2 -- family template count reconciliation : 11 tracked / 11 contracted / 13 on disk -- RESOLVED via #52 (option c, 2026-05-19)

- **title** : `[FAMILY-TEMPLATE-RECONCILE] templates/phase_z2/families/ has 13 .html files on disk but 11 tracked + 11 frame_contracts entries; 2 WIP files (app_sw_package_vs_solution.html, pre_construction_model_info_stacked.html) untracked`
- **source_axis** : Axis 3 (invariant category C6 template / catalog / frame count) -- recorded in §5.2 C6 row + §5.4 follow-up bullet F-2 + §6.3 Axis 4 cross-axis consistency bullet.
- **scope** :
  - decide whether the 2 untracked WIP family templates (`app_sw_package_vs_solution.html`, `pre_construction_model_info_stacked.html`) should be (a) tracked + contracted (add to `frame_contracts.yaml`, add to `git ls-files`), (b) removed if abandoned, or (c) explicitly noted as in-progress with a parent issue.
  - reconcile the IMP-18 SVG-gap report doc citation `families/*.html (13)` against whichever decision is chosen (so the doc count matches code reality).
- **scope-lock** : touches `templates/phase_z2/families/*.html`, `templates/phase_z2/catalog/frame_contracts.yaml`, `docs/architecture/IMP-18-SVG-GAP-REPORT.md`. **Must NOT be folded into #19 silently**: any catalog growth needs a dedicated issue per [[feedback_workflow_atomicity_rules]] (one commit = one decision).
- **evidence_link** :
  - REPORT §5.2 row C6 ("AGREE FOR TRACKED BASELINE -- 11 tracked family templates <-> 11 frame_contracts entries").
  - REPORT §5.5 row "C6 family templates -- on disk" (`ls templates/phase_z2/families/*.html` = 13).
  - REPORT §6.3 Axis 4 cross-axis consistency bullet (matches IMP-04 evidence).
- **priority / gating** : **must land before #19 introduces any new family template** (per §9.3 condition 2). Until #19's catalog touch surface is known, this can be filed independently.
- **resolution** : option (c) -- 2 WIP family templates explicitly noted as in-progress and tracked outside `frame_contracts.yaml` (RESOLVED via Gitea #52, 2026-05-19) :
  - WIP allowlist : `templates/phase_z2/families/_WIP_FILES.md` (added by #52 u1) -- names both files with Figma frame IDs (`app_sw_package_vs_solution.html` -> frame 23 / `1171281203`; `pre_construction_model_info_stacked.html` -> frame 9 / `1171281180`) and explicit "not in `frame_contracts.yaml`, not in runtime matcher set" status; promote / remove gated on Gitea #42.
  - IMP-18 doc reconciled : `docs/architecture/IMP-18-SVG-GAP-REPORT.md` L28 + L30 + L51 corrected from disk-only "13 files" / "15 partials" wording to "11 contracted + 2 WIP untracked = 13 on disk" (#52 u2) -- runtime matcher consumes the contracted set only; doc / tracked / contracted surfaces agree at 11 active.
  - baseline guard (planned by #52 u4) : `tests/test_family_contract_baseline.py` will enforce tracked families <-> `frame_contracts.yaml` 1:1 set-equality modulo WIP allowlist parsed from `_WIP_FILES.md`; future drift (#42 or otherwise) fails CI.
  - tracked baseline (11 contracted families <-> 11 `frame_contracts.yaml` entries) unchanged; no contract entries added or removed; no runtime matcher mutation; **C6 invariant remains AGREE** for the closed-issue audit scope.
  - **F-2 closed-by-#52** under [[feedback_workflow_atomicity_rules]] (one commit = one decision unit), without re-opening any §5 C-invariant or §6.3 Axis 4 conclusion. #19 catalog-touch gate (per §9.3 condition 2) is now satisfied for the current 11/11 baseline; any #19 / #42 catalog growth must reconcile the WIP allowlist before merge.

### 10.3 F-3 -- backlog status sweep : 15 rows pending->implemented + 1 row pending->documented(deferred) + IMP-15 children footnote

- **title** : `[BACKLOG-STATUS-SWEEP] PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md has 16 of 22 audited rows mislabeled as pending; flip 15 to implemented, 1 (IMP-17) to documented (deferred), footnote IMP-15 with 5 execution children`
- **source_axis** : Axis 4 (backlog vs code reality) -- recorded in §6.1 headline finding + §6.2 22-row matrix + §6.3 follow-up candidate F-3 + §9.1 §6 row + §9.3 condition 1.
- **scope** :
  - **15 rows** to flip `pending` -> `implemented` : IMP-02, IMP-03, IMP-04, IMP-05, IMP-06, IMP-07, IMP-08, IMP-09, IMP-10, IMP-11, IMP-12, IMP-13, IMP-14, IMP-15 (parent), IMP-16.
  - **1 row** to flip `pending` -> `documented (deferred)` : IMP-17 (status-class shift; runtime AI = 0, 3-cond AND gate closed; matches §6.2 row 16).
  - **IMP-15 row** : add inline footnote citing the 5 execution children commits `#45 (e9b3d2e)`, `#46 (2827622)`, `#47 (535c484)`, `#48 (614c533)`, `#49 (verification-only, re-uses 614c533)`. Either as a footnote on the IMP-15 row or as 5 child stub rows -- pick one and apply consistently.
  - **IMP-18 row** : leave as `documented` (already AGREE per §6.2 row 17).
- **scope-lock** : single-file edit to `docs/architecture/PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md`. **Doc-only**, zero `src/**` / `templates/**` / `tests/**` edits. Must be filed as a separate Gitea issue with its own Stage 5 commit (not merged into #19 or any other improvement issue).
- **evidence_link** :
  - REPORT §6.1 headline finding (16 BACKLOG_STALE + 5 NO_BACKLOG_ROW + 1 AGREE = 22).
  - REPORT §6.2 22-row matrix (per-row grep evidence + commit SHAs).
  - REPORT §6.3 follow-up reference.
  - REPORT §9.1 / §9.3 condition 1 ("F-3 backlog sweep should land before #19 Stage 2 planning consumes the backlog").
- **priority / gating** : **highest of the 5 candidates**. **Must land before #19 Stage 2 planning** (per §9.3 condition 1) so that #19's planner reads accurate `implemented` / `documented (deferred)` status and does not treat already-wired features as still pending.

### 10.4 F-4 -- legacy Phase R' / Q sample-literal cleanup (OPTIONAL)

- **title** : `[LEGACY-LITERAL-CLEANUP] 20 hits of 재구성 / 건설산업 DX / BIM across 10 legacy Phase R'/Q files (block_assembler_b2.py, block_matcher_tfidf.py, block_reference.py, content_editor.py, design_director.py, design_tokens.py, fit_verifier.py, frame_extractor.py, kei_client.py, pipeline.py)`
- **source_axis** : Axis-supporting Section 8 (anti-hardcoding grep checklist) -- recorded in §8.1 row G3 + §8.2 third bullet + §9.1 §8 row.
- **scope** :
  - per-file review of the 20 legacy hits to determine which are docstrings / comments (keep), legacy taxonomy (keep with annotation), or true sample-literal pins (remove or generalize).
  - per-file counts to triage : `block_assembler_b2.py` 1, `block_matcher_tfidf.py` 1, `block_reference.py` 3, `content_editor.py` 3, `design_director.py` 2, `design_tokens.py` 1, `fit_verifier.py` 1, `frame_extractor.py` 1, `kei_client.py` 4, `pipeline.py` 3.
  - **NOT** touching the 11 Phase Z hits (`phase_z2_content_extractor.py` 7 self-test data, `phase_z2_failure_router.py:123` taxonomy, `phase_z2_mapper.py:519/529` docstring examples, `phase_z2_retry.py:59` docstring) -- those passed audit verdict G3.
- **scope-lock** : potentially touches legacy `src/**` files NOT in the Phase Z 22-step pipeline. Must be filed as a deliberate cleanup issue with its own scope-lock. If any file flagged here turns out to be on a live Phase Z code path on review, demote the candidate or split it.
- **evidence_link** :
  - REPORT §8.1 row G3 (per-file count breakdown, audit date 2026-05-19).
  - REPORT §8.2 third bullet (20 legacy + 11 Phase Z = 31, reconciliation).
  - Raw grep output : `D:\ad-hoc\kei\design_agent\.orchestrator\tmp\50_grep_checklist_raw.txt`.
- **priority / gating** : **optional, low priority, doc-only follow-up note**. Does NOT gate #19; §8 verdict already PASS for audit scope. Recorded for completeness so future audits do not re-discover the same 20-hit baseline.

### 10.5 F-5 -- formalize tests/fixtures/ directory (OPTIONAL)

- **title** : `[TESTS-FIXTURES-FORMALIZE] tests/fixtures/ directory does not exist; sample MDX references currently live in tests/phase_z2/test_pz2_vu_integration.py`
- **source_axis** : Axis-supporting Section 8 (anti-hardcoding grep checklist G6) -- recorded in §8.1 row G6 + §8.2 fourth bullet.
- **scope** :
  - if-and-only-if sample inventory grows beyond what fits inside `tests/phase_z2/test_*.py` files, formalize a `tests/fixtures/` directory holding sample-specific fixtures.
  - migrate existing `samples/mdx_batch/02.mdx` references in `tests/phase_z2/test_pz2_vu_integration.py:6, 82` only if migration is part of a broader test-fixture refactor (otherwise leave them as integration smoke).
  - update the issue-body rule wording to acknowledge that `tests/phase_z2/test_*.py` already discharges the spirit of "no sample-specific fixtures in production pipeline".
- **scope-lock** : touches `tests/fixtures/` (new directory if filed) + the cited test files. Must NOT be folded into any unrelated test refactor.
- **evidence_link** :
  - REPORT §8.1 row G6 verdict "PASS WITH NOTE".
  - REPORT §8.2 fourth bullet (`tests/fixtures/` not yet established).
- **priority / gating** : **optional, very low priority**. Filing is only justified when sample inventory grows; the current state is already aligned with the spirit of the rule.

#### 10.5.1 F-5 docs-only resolution addendum (#54 Stage 3 u5, 2026-05-19)

Per issue #54 Stage 2 plan, F-5 is closed as **docs-only**; no root `tests/fixtures/` directory is created in this work. The current fixture inventory does not justify migration, and the existing convention is sufficient. The convention is recorded here so future anti-hardcoding audits can distinguish fixture / test-only paths from production paths without re-discovering the §8 G6 PASS-WITH-NOTE baseline.

- **Existing convention (DO NOT CHANGE)** : `tests/phase_z2/fixtures/` exists as a YAML regression fixture root (loaded by `tests/phase_z2/test_fixtures_loader.py`). Subdirectories present at audit time : `tests/phase_z2/fixtures/build_layout_css/`, `tests/phase_z2/fixtures/retry_gate/`. This is the canonical home for Phase Z regression fixtures.
- **Root `tests/fixtures/` (ABSENT)** : not created in #54. If a future change requires a non-Phase-Z, non-YAML fixture corpus (for example, multi-file MDX golden inputs that grow beyond what `tests/phase_z2/test_*.py` can hold inline), the migration must be filed as its own Gitea issue with its own scope-lock per §10.5.
- **Allowed sample references** : `samples/mdx_batch/**` and `samples/mdx/**` may be referenced from `tests/**` (test-only paths) for integration smoke -- e.g. the existing `samples/mdx_batch/02.mdx` references in `tests/phase_z2/test_pz2_vu_integration.py`. These do not violate the §8 anti-hardcoding rule because the spirit of the rule targets production pipeline code, not test runners.
- **Forbidden sample references** : production pipeline code (`src/**` runtime path) must NOT hardcode sample-specific MDX filenames or content (e.g. `02.mdx`, `03.mdx`, frame-specific labels keyed to a sample). The 20 legacy Phase R'/Q hits annotated under F-4 (#54 Stage 3 u1-u4) are intentional documented examples in docstrings / comments / glossary regex / sample-data dicts, not runtime input pins; they are out of scope for this rule by §10.4 verdict.
- **AI-isolation contract** : this addendum is text-only. No production behavior change, no runtime sample-path mutation, no new fixture file. Compatible with PZ-1 (AI = 0 on normal path) and [[feedback_ai_isolation_contract]].
- **Cross-reference** : `tests/CLAUDE.md` fixture convention note (#54 Stage 3 u5) mirrors the test-only / production rule split documented here.

### 10.6 Follow-up summary

| candidate | source axis | doc-only? | gates #19? | priority |
|---|---|---|---|---|
| F-1 audit-charter producer file path | Axis 3 (§5) | YES | NO | low (charter cleanup) |
| F-2 family template count reconcile | Axis 3 (§5) | NO -- touches templates / catalog / docs | gate IF #19 extends catalog | medium |
| F-3 backlog status sweep | Axis 4 (§6) | YES | YES -- must land before #19 Stage 2 plan | **highest** |
| F-4 legacy R'/Q literal cleanup | §8 (anti-hardcoding) | NO -- legacy src/ touch surface | NO | low (optional) |
| F-5 tests/fixtures/ formalize | §8 (anti-hardcoding) | NO -- tests/ migration | NO | very low (optional) |

- **Counts** : 5 candidates total. 3 are blocking conditions for upgrading §9 CONDITIONAL GO to unconditional GO for #19 (F-3 hard-gates, F-2 conditional-gates on catalog touch, F-1 nice-to-have before next audit). 2 are optional housekeeping (F-4, F-5).
- **Compliance with Stage 2 u6 contract** : per-draft fields (title / source_axis / scope / evidence_link) populated for each of F-1 .. F-5. **Zero auto-posts** -- this section is text-only. Filing decisions = orchestrator / human after #50 closes.
- **AI-isolation contract** : none of the 5 follow-up candidates require AI on a normal path. F-2 / F-4 / F-5 are scope decisions to be made by a human reviewer. Compatible with [[feedback_ai_isolation_contract]] and PZ-1 (AI = 0 on normal path).
