## IMP — Step 12 AI hook geometry fix (heights_px ValueError 차단)
**관련 step**: Step 12 (AI repair) — backend `_compute_per_zone_geometry` + AI hook prerequisite
**source**: 2026-05-22 fresh validation — #76 IMP-47B closed + .env AI_FALLBACK_ENABLED=true 적용 후 mdx03 reject override 시 AI 호출 도달 못 함
**roadmap axis**: R3 (AI 재구성)
**wave**: P0 (즉시 — reject / all-reject path 의 공통 blocker)
**priority**: ★ 최우선
**dependency**: #61 IMP-33 closed, #76 IMP-47B closed, `.env` AI_FALLBACK_ENABLED=true
### Evidence (fresh validation 2026-05-22)
mdx03 reject override → AI 호출 직전 crash:
`
$ python -m src.phase_z2_pipeline samples/mdx_batch/03.mdx mdx03_reject_val_xxx \
--override-frame "03-2=bim_dx_comparison_table"
adapter : zone--bottom ['03-2'] → bim_dx_comparison_table FitError → adapter_needed (skip render)
ValueError: _compute_per_zone_geometry: heights_px length 1 != grid rows R=2
(css_areas='"top" "bottom"')
`
즉:
- `_apply_frame_override_to_unit` 가 `unit.label="reject"` + `provisional=True` 정상 마킹
- 그러나 `adapter_needed` 분기 후 `layout_css` 의 `heights_px` shape 가 grid_rows R 과 불일치
- AI router 의 entry 도달 불가 → `step12_ai_repair.json` 미생성 → AI 호출 0
### 구조 / 원인 추정
- `adapter_needed` (FitError) path 와 AI fallback path 의 분기 가 명확하지 않음
- reject context 의 `layout_css` 가 fallback shape (single row 등) 으로 생성되어 grid_rows 와 불일치
- 또는 `adapter_needed` 가 zone 의 `heights_px` 를 정리하지 않고 단순 skip → 다음 step 의 invariant violation
### scope
- `_compute_per_zone_geometry` 의 reject / provisional 컨텍스트 처리 검증
- `heights_px` / `widths_px` 가 grid_rows(R) / cols(C) 와 **항상 일치** 하도록 invariant
- reject 케이스 의 `layout_css` 가 정상 shape 유지
- `_apply_frame_override_to_unit` 의 reject path 가 layout_css 를 적절히 갱신하는지 검증
- `adapter_needed` (FitError) path 와 AI fallback path 의 명확한 분기:
- reject + provisional → AI router 로 (skip render 가 아니라)
- non-reject FitError → adapter_needed (기존 동작)
- AI router 의 entry 도달 보장 (router gate 자체 는 정상, 그 직전 prerequisite 의 shape)
### out of scope
- AI router 자체 (#61 IMP-33, #76 IMP-47B 가 cover)
- AI proposal validation / cache (#62 IMP-46 axis)
- AI model ID validation (P1: 별 issue 후보)
### guardrail / validation
- **mdx03 reject override** → AI 호출 도달:
- `step12_ai_repair.json` 생성 확인
- `ai_called=True` 또는 의미 있는 `skip_reason` 명시
- heights_px ValueError 없음
- mdx03 default (use_as_is path) 회귀 X
- pytest reject route 관련 케이스 모두 PASS
- `_compute_per_zone_geometry` invariant unit test 추가
### relevant feedback
- `feedback_ai_isolation_contract`: AI = fallback only, frame visual 보존, MDX 보존
- `feedback_factual_verification`: silent crash 금지, 명확한 error / log
- `feedback_validation_first_for_closed_issues`: #76 closed 후 fresh validation 잔여 axis

🤖 Claude Opus 4.7 (multi-angle validation, 2026-05-22)
Root cause (verified by fresh reproduction 2026-05-23)
The ValueError is NOT an AI-router-entry issue. It is a zones_data / debug_zones truncation invariant violation in the mapper loop that crashes the pipeline AFTER step12_ai_repair.json is already written. Chain (4 hops):
src\phase_z2_pipeline.py:4945 → _compute_per_zone_geometry(layout_css, debug_zones, GRID_GAP) parses css_areas = '"top" "bottom"' → R=2, but heights_px=1 → ValueError at src\phase_z2_pipeline.py:1500-1505.
Issue body claim corrections (factual)
Issue body claim
Actual finding
"AI router 의 entry 도달 불가"
WRONG. AI router IS reached. step12_ai_repair.json per_unit[1] shows ai_called=True, route_hint=ai_adaptation_required, provisional=True. The AI call then fails with a separate 404 NotFoundError on model id claude-opus-4-6-20250415 — that is the P1 "AI model ID validation" item the body itself lists as out-of-scope.
"step12_ai_repair.json 미생성"
WRONG. The artifact IS written. _write_step_artifact(run_dir, 12, "ai_repair", ...) at src\phase_z2_pipeline.py:4900-4911 runs before the geometry crash at line 4945. Verified by ls .../steps/.
"heights_px ValueError 차단"
CORRECT. Real blocker. Pipeline aborts before final.html / visual check.
Second-order defect (uncovered while tracing)
Even if the ValueError is masked (e.g. wrap in try/except), the reject-route AI proposal still cannot land: _apply_ai_repair_proposals_to_zones (src\phase_z2_pipeline.py:642-684) builds zone_by_position from zones_data. For the FitError-skipped unit, zone_by_position.get("bottom") returns None → apply_status = "no_zone_match" → PARTIAL_OVERRIDES proposal never merges into render. So the geometry fix and the AI-application fix share a single root: reject-route units must produce a placeholder zones_data/debug_zones entry so (a) layout_css invariant holds and (b) the apply pass has a target zone to mutate.
Scope-lock
In scope (this issue):
Mapper-loop FitError branching:
unit.label == "reject" and unit.provisional → emit placeholder zones_data + debug_zones entry (template_id = unit.frame_template_id, empty slot_payload = {}, min_height_px from frame_contract.visual_hints, provisional=True). Do NOT append to adapter_needed_units.
All other FitError → existing adapter_needed_units path unchanged.
_compute_per_zone_geometry invariant guarded by a unit test that pins heights_px length == R / widths_px length == C across the placeholder shape.
_apply_ai_repair_proposals_to_zones round-trip: reject placeholder zone is reachable by zone_by_position[position] → PARTIAL_OVERRIDES proposal.payload.slots merges into zone["slot_payload"].
G3 (geometry invariant): pytest tests/phase_z2/test_compute_per_zone_geometry.py PASS + new case test_reject_placeholder_preserves_grid_invariant PASS — heights_px length == R after a reject placeholder zone, css_areas unchanged.
G4 (apply path lands): step12_ai_repair.json per_unit[1].apply_status NOT in {no_zone_match}. On 404 model error the expected value is no_proposal with the existing 404 error string — that is acceptable for this issue and surfaces the separate model-id axis cleanly. When a valid cached / stub proposal is available, applied:partial_overrides should be visible (covered by a fixture-driven test, not a live AI call).
G5 (non-reject FitError preserved): a synthetic non-reject FitError unit (e.g. inject FitError on a use_as_is template) still routes to adapter_needed_units, still skips render, no zones_data entry — byte-identical regression.
G6 (default path regression): mdx03 default (no overrides, no persisted file) byte-identical to pre-fix run — debug.json zones[].template_id, heights_px, ratios, step12_ai_repair.json shape.
feedback_ai_isolation_contract — AI repair must NOT swap frame visual / contract; placeholder zone keeps frame_template_id post-override.
feedback_factual_verification — Stage 1 evidence below shows value + path + upstream for every claim. Unknowns explicit (model-id 404 is observed but out-of-scope).
feedback_validation_first_for_closed_issues — #76 closed, but fresh reproduction shows AI router IS reached; the new failure is a different axis (geometry), confirming the body's premise needs the correction in §"Issue body claim corrections" above.
feedback_phase_z_spacing_direction — fix direction is emit placeholder zone, NOT collapse layout to single row. Layout/zone topology preserved.
feedback_no_hardcoding — placeholder uses frame_contract.visual_hints.min_height_px (no magic constants).
Implementation unit sketch (for Stage 2 plan, NOT a commitment)
u1 — mapper loop FitError branch on (unit.label=="reject" and unit.provisional) → placeholder zones_data/debug_zones append. Existing __empty__ shell at src\phase_z2_pipeline.py:4300-4353 is the structural template (mirror the field shape including _popup_payload, assignment_source, placement_trace=None, etc.). Keep mapper_type="reject_placeholder" for telemetry differentiation from __empty__.
u2 — unit test test_compute_per_zone_geometry_with_reject_placeholder in tests/phase_z2/test_compute_per_zone_geometry.py: synthesize horizontal-2 layout_css + debug_zones with one normal + one reject placeholder → no ValueError, heights_px length == 2.
u3 — integration test in tests/test_imp47b_override_provisional.py (or new sibling) for the full reject override path: ai_called=True, apply_status one of {applied:partial_overrides (fixture-driven), no_proposal (404 graceful)}. NO no_zone_match.
u4 — regression test: non-reject FitError synthetic unit still hits adapter_needed_units, no zones_data entry, no ValueError, status note carries the existing message.
u5 — fresh mdx03 default smoke (no overrides, no persisted user_overrides) → byte-identical regression vs pre-fix on debug.json critical fields. Confirms G6.

## Root cause (verified by fresh reproduction 2026-05-23)
The ValueError is NOT an AI-router-entry issue. It is a **zones_data / debug_zones truncation invariant violation in the mapper loop** that crashes the pipeline AFTER `step12_ai_repair.json` is already written. Chain (4 hops):
1. `--override-frame "03-2=bim_dx_comparison_table"` →
`D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py:1196-1208` (`_apply_frame_override_to_unit`, probe layer 2 = `v4_reject_judgment_provisional`) → `unit.label = "reject"` + `unit.provisional = True` + frame_template_id swapped. Visual / contract untouched (AI isolation contract preserved).
2. Mapper loop at `src\phase_z2_pipeline.py:4434-4448` calls `map_mdx_to_slots(synth_section, "bim_dx_comparison_table")` → raises `FitError` (reject = mapper has no payload path).
3. FitError handler appends unit to `adapter_needed_units` and `continue`s. **No zones_data entry, no debug_zones entry** for the bottom zone.
4. `src\phase_z2_pipeline.py:4938` → `build_layout_css("horizontal-2", zones_data, ...)` → `_build_rows_dynamic` (`src\phase_z2_pipeline.py:1577-1604`) → `compute_zone_layout(zones_data)` returns `heights_px` with length **`len(zones_data) = 1`**, matching zones-list cardinality not preset row count.
5. `src\phase_z2_pipeline.py:4945` → `_compute_per_zone_geometry(layout_css, debug_zones, GRID_GAP)` parses `css_areas = '"top" "bottom"'` → R=2, but heights_px=1 → `ValueError` at `src\phase_z2_pipeline.py:1500-1505`.

## Second-order defect (uncovered while tracing)
Even if the ValueError is masked (e.g. wrap in try/except), the reject-route AI proposal still cannot land: `_apply_ai_repair_proposals_to_zones` (`src\phase_z2_pipeline.py:642-684`) builds `zone_by_position` from `zones_data`. For the FitError-skipped unit, `zone_by_position.get("bottom")` returns `None` → `apply_status = "no_zone_match"` → PARTIAL_OVERRIDES proposal never merges into render. So **the geometry fix and the AI-application fix share a single root**: reject-route units must produce a placeholder zones_data/debug_zones entry so (a) layout_css invariant holds and (b) the apply pass has a target zone to mutate.
## Scope-lock
In scope (this issue):
1. Mapper-loop FitError branching:
- `unit.label == "reject" and unit.provisional` → emit placeholder zones_data + debug_zones entry (`template_id = unit.frame_template_id`, empty `slot_payload = {}`, `min_height_px` from frame_contract.visual_hints, `provisional=True`). **Do NOT append to `adapter_needed_units`**.
- All other FitError → existing `adapter_needed_units` path unchanged.
2. `_compute_per_zone_geometry` invariant guarded by a unit test that pins heights_px length == R / widths_px length == C across the placeholder shape.
3. `_apply_ai_repair_proposals_to_zones` round-trip: reject placeholder zone is reachable by `zone_by_position[position]` → PARTIAL_OVERRIDES `proposal.payload.slots` merges into `zone["slot_payload"]`.
Out of scope (separate axes per issue body):
- AI router internals (#61 IMP-33, #76 IMP-47B)
- AI proposal validation / cache (#62 IMP-46)

🤖 Claude Opus 4.7 (root-cause verified by fresh reproduction, 2026-05-23)
Scope-lock result: accept the root cause, with one reproduction correction that must be carried into Stage 2/4 validation.
The geometry failure is a real general pipeline invariant bug, not an AI-router-entry bug. The mapper loop can drop a renderable unit from both zones_data and debug_zones on FitError, while the selected layout preset still has its full catalog grid. For the unmasked horizontal-2 shape, build_layout_css("horizontal-2", zones_data_one) returns areas='"top" "bottom"' but heights_px=[585]; _compute_per_zone_geometry(...) then raises ValueError: heights_px length 1 != grid rows R=2.
Verified chain:
src/phase_z2_pipeline.py:1165_apply_frame_override_to_unit promotes a full-32 reject judgment override to unit.label="reject" and unit.provisional=True while preserving the requested frame template.
src/phase_z2_pipeline.py:4435 calls map_mdx_to_slots(...); the FitError handler at src/phase_z2_pipeline.py:4436-4448 appends adapter_needed_units and continues before any zones_data or debug_zones entry is created.
Normal zone/debug entries are only appended after mapper success at src/phase_z2_pipeline.py:4490-4541.
src/phase_z2_pipeline.py:1577-1604_build_rows_dynamic delegates row heights to compute_zone_layout(zones_data), and src/phase_z2_pipeline.py:1246-1299 computes one height per surviving zones_data item, not one height per catalog grid row.
src/phase_z2_pipeline.py:1477-1539_compute_per_zone_geometry correctly treats mismatched heights_px / grid rows as a broken build path and raises.
AI-router facts:
src/phase_z2_pipeline.py:4867-4911 runs _run_step12_ai_repair(units), applies records, and writes step12_ai_repair.json before layout CSS and per-zone geometry at src/phase_z2_pipeline.py:4938-4945.
Live artifact data/runs/mdx03_reject_val_codex86_r1/phase_z2/steps/step12_ai_repair.json has per_unit[1].ai_called=true, route_hint="ai_adaptation_required", provisional=true, and error="NotFoundError: ... model: claude-opus-4-6-20250415".
That model-id 404 is real but out of scope for this issue, matching the issue body's P1 exclusion.
Second-order defect confirmed:
src/phase_z2_pipeline.py:642-684_apply_ai_repair_proposals_to_zones indexes only existing zones_data by position.
If the FitError-skipped unit later has a partial_overrides proposal, its position has no zone entry, so apply_status becomes no_zone_match and the proposal cannot affect rendering.
Existing test text in tests/test_imp47b_payload_apply.py already documents the same dropped-unit shape; a direct helper probe reproduced apply_status="no_zone_match" with unit_positions=["top","bottom"] and only the top zone present.
Correction to Claude's fresh reproduction claim:
In this workspace, the literal command from the issue body does not currently crash because data/user_overrides/03.json exists and is auto-loaded by src/phase_z2_pipeline.py:6207-6224.
That persisted file injects layout="vertical-2" plus left/right zone_geometries, so the run mdx03_reject_val_codex86_r1 completed with PASS, adapter_needed_count=1, and no ValueError.
Stage 2/4 validation must neutralize persisted user overrides or explicitly control layout/geometry, otherwise the mdx03 command is not testing the reported horizontal-2 failure mode.
Scope recommendation:
Fix the shared root, not the exception site: FitError / adapter-needed units that still occupy a layout position need structural placeholder zones_data and debug_zones entries. That keeps layout_css track arrays aligned with catalog positions and gives Step 12 proposal application a zone target.
Keep the behavior general across layout presets and positions; do not special-case mdx03, section 03-2, horizontal-2, or bim_dx_comparison_table.
Preserve AI isolation: the placeholder should preserve frame identity and source coverage while marking the unit as adapter-needed / provisional / human-review-required rather than silently rendering fake content.
The live mdx03 command in this workspace is masked by persisted user overrides and exits PASS, so validation must control that prerequisite.
step12_ai_repair.json is written before geometry and shows the reject override reached the AI route.
The configured AI model id is claude-opus-4-6-20250415, and the live run recorded a 404 NotFoundError for that id.
A skipped adapter-needed unit with an AI proposal cannot currently apply because there is no matching zones_data entry.

- `src/phase_z2_pipeline.py:4435` calls `map_mdx_to_slots(...)`; the `FitError` handler at `src/phase_z2_pipeline.py:4436-4448` appends `adapter_needed_units` and `continue`s before any `zones_data` or `debug_zones` entry is created.
- Normal zone/debug entries are only appended after mapper success at `src/phase_z2_pipeline.py:4490-4541`.
- `src/phase_z2_pipeline.py:1577-1604` `_build_rows_dynamic` delegates row heights to `compute_zone_layout(zones_data)`, and `src/phase_z2_pipeline.py:1246-1299` computes one height per surviving `zones_data` item, not one height per catalog grid row.
- `src/phase_z2_pipeline.py:1477-1539` `_compute_per_zone_geometry` correctly treats mismatched `heights_px` / grid rows as a broken build path and raises.
AI-router facts:
- `src/phase_z2_pipeline.py:4867-4911` runs `_run_step12_ai_repair(units)`, applies records, and writes `step12_ai_repair.json` before layout CSS and per-zone geometry at `src/phase_z2_pipeline.py:4938-4945`.
- Live artifact `data/runs/mdx03_reject_val_codex86_r1/phase_z2/steps/step12_ai_repair.json` has `per_unit[1].ai_called=true`, `route_hint="ai_adaptation_required"`, `provisional=true`, and `error="NotFoundError: ... model: claude-opus-4-6-20250415"`.
- That model-id 404 is real but out of scope for this issue, matching the issue body's P1 exclusion.
Second-order defect confirmed:
- `src/phase_z2_pipeline.py:642-684` `_apply_ai_repair_proposals_to_zones` indexes only existing `zones_data` by position.
- If the FitError-skipped unit later has a `partial_overrides` proposal, its position has no zone entry, so `apply_status` becomes `no_zone_match` and the proposal cannot affect rendering.
- Existing test text in `tests/test_imp47b_payload_apply.py` already documents the same dropped-unit shape; a direct helper probe reproduced `apply_status="no_zone_match"` with `unit_positions=["top","bottom"]` and only the top zone present.
Correction to Claude's fresh reproduction claim:
- In this workspace, the literal command from the issue body does not currently crash because `data/user_overrides/03.json` exists and is auto-loaded by `src/phase_z2_pipeline.py:6207-6224`.
- That persisted file injects `layout="vertical-2"` plus left/right `zone_geometries`, so the run `mdx03_reject_val_codex86_r1` completed with `PASS`, `adapter_needed_count=1`, and no `ValueError`.
- Stage 2/4 validation must neutralize persisted user overrides or explicitly control layout/geometry, otherwise the mdx03 command is not testing the reported `horizontal-2` failure mode.
Scope recommendation:
- Fix the shared root, not the exception site: FitError / adapter-needed units that still occupy a layout position need structural placeholder `zones_data` and `debug_zones` entries. That keeps `layout_css` track arrays aligned with catalog positions and gives Step 12 proposal application a zone target.
- Keep the behavior general across layout presets and positions; do not special-case mdx03, section `03-2`, `horizontal-2`, or `bim_dx_comparison_table`.
- Preserve AI isolation: the placeholder should preserve frame identity and source coverage while marking the unit as adapter-needed / provisional / human-review-required rather than silently rendering fake content.

Verified facts:
- `_compute_per_zone_geometry` raises on one-zone `horizontal-2` layout CSS: `heights_px length 1 != grid rows R=2`.
- The live mdx03 command in this workspace is masked by persisted user overrides and exits `PASS`, so validation must control that prerequisite.
- `step12_ai_repair.json` is written before geometry and shows the reject override reached the AI route.
- The configured AI model id is `claude-opus-4-6-20250415`, and the live run recorded a 404 NotFoundError for that id.
- A skipped adapter-needed unit with an AI proposal cannot currently apply because there is no matching `zones_data` entry.

FINAL_CONSENSUS: YES
unit_executed: u1 — mapper FitError handler preserves failed unit position by appending a placeholder zones_data record and matching debug_zone so grid cardinality stays aligned with the active layout preset.
diff_summary:
In src/phase_z2_pipeline.py at the mapper FitError except branch (previously appending only to adapter_needed_units then continue), the handler now ALSO appends:
A placeholder zones_data record using template_id="__empty__" (mirroring the IMP-30 empty-shell pattern at src/phase_z2_pipeline.py:4306, so render_slide (src/phase_z2_pipeline.py:2572) short-circuits to empty partial_html), with:
slot_payload={}
content_weight={"score": 0} (so compute_zone_layout weight distribution does not double-count the placeholder)
min_height_px=min_height_px (already derived from the resolved contract visual_hints.min_height_px at line 4364)
assignment_source="imp86_u1_adapter_needed" (placeholder marker — refined in u5)
adapter_needed_units is unchanged (still the authoritative adapter signal). The original print() line and continue remain after the appends. _apply_frame_override_to_unit, the AI router gate (_run_step12_ai_repair), frame override semantics, and the layout preset catalog are all untouched.
why this resolves the heights_px ValueError:
Before: zones_data / debug_zones only received units whose mapper succeeded, while build_layout_css(layout_preset, zones_data, …) (src/phase_z2_pipeline.py:4938) still returned a layout shape sized to the preset catalog's grid rows (R from css_areas). For mdx03 reject override (--override-frame "03-2=bim_dx_comparison_table") on the horizontal-2 preset, this produced heights_px=[585] (length 1 from _build_rows_dynamic → compute_zone_layout(zones_data)) vs R=2, raising ValueError("heights_px length 1 != grid rows R=2") at _compute_per_zone_geometry (src/phase_z2_pipeline.py:1500-1505).
After: the placeholder keeps len(zones_data) == R, so compute_zone_layout emits a length-R heights_px, and _compute_per_zone_geometry's invariant holds. The per-zone helper aggregates a valid row span for the placeholder position; Step 12 _run_step12_ai_repair continues past Step 7/8 without crashing and the AI router prerequisite is satisfied (consistent with the existing artifact per_unit[1] ai_called=true, route_hint=ai_adaptation_required from the prior partial-run evidence).
scope adherence:
AI isolation contract preserved — frame visual untouched, no auto frame swap, only zones_data cardinality fix.
No MDX edits, no template_id rewrite, no preset catalog change.
No-hardcoding: the placeholder uses min_height_px already derived from the resolved contract; no MDX-specific or sample-specific values.
Phase Z spacing direction: cardinality preserved by ADDING a placeholder row, never by shrinking content.
No tests added in this turn — coverage is u3 (unit) and u4 (integration) per Stage 2 plan. Pytest run deferred to those units; the Stage 3 deliverable is the implementation, with consensus across u3+u4 providing the verification axis.
remaining_units:
u2 — pre-build_layout_css invariant guard with preset/positions/count diagnostics
u3 — unit coverage for horizontal-2 normal+placeholder geometry (R=2 preservation)
u4 — integration coverage for mdx03 reject override → Step 12 AI router reachable, default-path regression
u5 — telemetry fields on placeholder/debug records (adapter_needed=True, mapper_fit_error, provisional mirror) while preserving adapter_needed_units semantics
follow_up_issue_candidates:
v4_b4_mismatch path at src/phase_z2_pipeline.py:4410-4430 exhibits the SAME cardinality drift (appends only adapter_needed_units, no placeholder zones_data / debug_zones). Default OFF via PHASE_Z_B4_GATEKEEPER env var so it does NOT trigger under default operation, but should the gatekeeper be enabled it would reproduce the same ValueError. Out of scope for #86 (FitError handler only per Stage 1 exit report) — candidate for a separate IMP issue.
AI model id 404 (claude-opus-4-6-20250415) — separate model-ID-validation track per Stage 1.

In `src/phase_z2_pipeline.py` at the mapper FitError `except` branch (previously appending only to `adapter_needed_units` then `continue`), the handler now ALSO appends:
1. A placeholder `zones_data` record using `template_id="__empty__"` (mirroring the IMP-30 empty-shell pattern at `src/phase_z2_pipeline.py:4306`, so `render_slide` (`src/phase_z2_pipeline.py:2572`) short-circuits to empty `partial_html`), with:
- `slot_payload={}`
- `content_weight={"score": 0}` (so `compute_zone_layout` weight distribution does not double-count the placeholder)
- `min_height_px=min_height_px` (already derived from the resolved contract `visual_hints.min_height_px` at line 4364)
- `assignment_source="imp86_u1_adapter_needed"` (placeholder marker — refined in u5)
- `section_assignment_override=False`
- `provisional=bool(getattr(unit, "provisional", False))`
- `**compose_zone_popup_payload(unit, 0)` — matches the empty-shell no-popup branch.
2. A matching `debug_zones` record preserving the original V4 evidence (`v4_rank1_frame_id`, `v4_rank1_frame_number`, `v4_template_id`, `v4_label`, `v4_confidence`, `v4_selected_rank`, `selection_path`, `fallback_reason`, `fallback_used`, `phase_z_status`, `composition_score`, `composition_rationale`, `composition_notes`, `placement_trace`), with:
- `mapper_type="adapter_needed"`
- `contract_id=unit.frame_template_id` (original target preserved for AI router / debug context)
- `contract_frame_id=contract_frame_id`, `builder=builder_name`, `min_height_px=min_height_px`
- `slot_payload_keys=[]`, `content_truncated_count=None`, `assets_dir=None`, `content_weight={"score": 0}`
- `assignment_source="imp86_u1_adapter_needed"`, `section_assignment_override=False`
- `replaced_auto_unit=None`, `skipped_collided_auto_units=[]`, `uncovered_section_ids=[]`
- `skipped_reason="imp86_u1_adapter_needed_mapper_fit_error"`
- `provisional=bool(getattr(unit, "provisional", False))`
`adapter_needed_units` is unchanged (still the authoritative adapter signal). The original `print()` line and `continue` remain after the appends. `_apply_frame_override_to_unit`, the AI router gate (`_run_step12_ai_repair`), frame override semantics, and the layout preset catalog are all untouched.
**why this resolves the heights_px ValueError**:
- Before: `zones_data` / `debug_zones` only received units whose mapper succeeded, while `build_layout_css(layout_preset, zones_data, …)` (`src/phase_z2_pipeline.py:4938`) still returned a layout shape sized to the preset catalog's grid rows (R from `css_areas`). For mdx03 reject override (`--override-frame "03-2=bim_dx_comparison_table"`) on the horizontal-2 preset, this produced `heights_px=[585]` (length 1 from `_build_rows_dynamic` → `compute_zone_layout(zones_data)`) vs R=2, raising `ValueError("heights_px length 1 != grid rows R=2")` at `_compute_per_zone_geometry` (`src/phase_z2_pipeline.py:1500-1505`).
- After: the placeholder keeps `len(zones_data) == R`, so `compute_zone_layout` emits a length-R `heights_px`, and `_compute_per_zone_geometry`'s invariant holds. The per-zone helper aggregates a valid row span for the placeholder position; Step 12 `_run_step12_ai_repair` continues past Step 7/8 without crashing and the AI router prerequisite is satisfied (consistent with the existing artifact `per_unit[1] ai_called=true, route_hint=ai_adaptation_required` from the prior partial-run evidence).
**scope adherence**:
- AI isolation contract preserved — frame visual untouched, no auto frame swap, only zones_data cardinality fix.
- No MDX edits, no template_id rewrite, no preset catalog change.
- No-hardcoding: the placeholder uses `min_height_px` already derived from the resolved contract; no MDX-specific or sample-specific values.
- Phase Z spacing direction: cardinality preserved by ADDING a placeholder row, never by shrinking content.
- `_apply_frame_override_to_unit` reject/provisional semantics unchanged.
- v4_b4_mismatch path NOT touched (out of scope per Stage 1 — FitError handler only).
**verification (this turn, scope-qualified)**:
- `python -c "import ast; ast.parse(open('src/phase_z2_pipeline.py', encoding='utf-8').read())"` → `SYNTAX OK`.
- `git diff --stat src/phase_z2_pipeline.py` → `1 file changed, 60 insertions(+)`.
- No tests added in this turn — coverage is u3 (unit) and u4 (integration) per Stage 2 plan. Pytest run deferred to those units; the Stage 3 deliverable is the implementation, with consensus across u3+u4 providing the verification axis.
**remaining_units**:
- u2 — pre-`build_layout_css` invariant guard with preset/positions/count diagnostics
- u3 — unit coverage for horizontal-2 normal+placeholder geometry (R=2 preservation)
- u4 — integration coverage for mdx03 reject override → Step 12 AI router reachable, default-path regression
- u5 — telemetry fields on placeholder/debug records (`adapter_needed=True`, `mapper_fit_error`, provisional mirror) while preserving `adapter_needed_units` semantics
**follow_up_issue_candidates**:
- v4_b4_mismatch path at `src/phase_z2_pipeline.py:4410-4430` exhibits the SAME cardinality drift (appends only `adapter_needed_units`, no placeholder `zones_data` / `debug_zones`). Default OFF via `PHASE_Z_B4_GATEKEEPER` env var so it does NOT trigger under default operation, but should the gatekeeper be enabled it would reproduce the same `ValueError`. Out of scope for #86 (FitError handler only per Stage 1 exit report) — candidate for a separate IMP issue.
- AI model id 404 (`claude-opus-4-6-20250415`) — separate model-ID-validation track per Stage 1.
STOP — Stage 3 Round #1 deliverable is this Gitea comment; no commit / push this turn.
u1 is correct. In D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py, the mapper FitError branch at lines 4436-4508 still appends the original adapter_needed_units record, and now also appends one placeholder zones_data record plus one matching debug_zones record before the existing continue. This preserves the failed unit's preset position so downstream build_layout_css(...) and _compute_per_zone_geometry(...) see aligned zone/debug cardinality for the active layout preset.
Scope check: _apply_frame_override_to_unit, _run_step12_ai_repair, layout preset definitions, and the normal mapper success path were not changed by this diff. The change is limited to src/phase_z2_pipeline.py and git diff --numstat -- src/phase_z2_pipeline.py reports 60 0, matching the claimed +60/-0 edit shape.

[Claude #4] Stage 3 code-edit Round #2 — IMP-86 u2
Executing unit: u2
unit_executed: u2 — add a pre-build layout invariant guard with preset, positions, and count diagnostics immediately before build_layout_css / _compute_per_zone_geometry, so any future zones_data / debug_zones cardinality drift relative to the active layout preset's css_areas tokens fails fast at the pipeline boundary with a factual error message.
files_changed:
src/phase_z2_pipeline.py (insert pre-build invariant guard above the existing build_layout_css(...) call site; +32 lines, 0 deletions for this unit)
diff_summary:
In src/phase_z2_pipeline.py, immediately before the existing build_layout_css(layout_preset, zones_data, override_zone_geometries=...) call (now at src/phase_z2_pipeline.py:5030 after the inserted block), the handler now:
Resolves the active preset:
_active_preset = LAYOUT_PRESETS[layout_preset] — same catalog-backed dict used everywhere downstream (src/phase_z2_pipeline.py:4192positions = LAYOUT_PRESETS[layout_preset]["positions"], _compute_per_zone_geometry_parse_css_areas(layout_css["areas"]) at src/phase_z2_pipeline.py:1494).
Derives the authoritative position list from the catalog grid tokens:
_expected_positions = _parse_css_areas(_active_preset["css_areas"])[1] — uses the existing _parse_css_areas helper (src/phase_z2_pipeline.py:1313-1348), whose second return value is the ordered unique-token list (the R x C grid's distinct zone names). This is the same R-source _compute_per_zone_geometry uses internally, so a guard expressed in terms of these tokens is provably consistent with the downstream raise sites at src/phase_z2_pipeline.py:1500-1505 and :1506-1511.
Compares zones_data / debug_zones against the expected positions:
_actual_positions = [zd["position"] for zd in zones_data]
_debug_positions = [dz["position"] for dz in debug_zones]
The message names the function as phase_z2_pipeline pre-build layout invariant violation so log scrubbing can tell this guard apart from the existing _compute_per_zone_geometry raise sites (factual_verification: value + path + upstream + unknown surface).
build_layout_css(...) is then called exactly as before — the guard is a strict prefix, not a replacement. No call signature, no preset catalog, no LAYOUT_PRESETS import, no AI router, no _apply_frame_override_to_unit, no _run_step12_ai_repair, no override-frame semantics, and no normal mapper success path were touched.
why this complements u1:
u1 fixed the known zone-drop site (mapper FitError) by appending placeholder zones_data / debug_zones records so the active preset's grid rows R stay aligned with len(zones_data).
u2 is the structural defense: any future path (or any path we missed in this scope) that drops a zone before build_layout_css will now fail at the pipeline boundary with a self-explanatory error containing layout_preset, css_areas, expected vs actual positions, and counts. Without u2 the same drift would still surface as the confusing heights_px length N != grid rows R=M ValueError inside _compute_per_zone_geometry, four call frames deeper.
Together u1 + u2 satisfy the scope_lock + guardrail line "shape drift caught at pipeline boundary, not at geometry helper".
scope check:
AI isolation contract preserved (no AI-path edits).
No frame override semantics change.
No layout preset catalog change.
No adapter_needed_units semantics change.
No _compute_per_zone_geometry raise site change.
1 commit = 1 decision unit (u2 is a single named decision: structural invariant at pipeline boundary).

[Codex #4] Stage 3 code-edit verification - IMP-86 u2
Verified only the single executed unit: u2.
u2 is correct. In D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py, the pre-build layout invariant guard is inserted immediately before the existing build_layout_css(...) call at lines 4998-5030. It derives the expected zone positions from LAYOUT_PRESETS[layout_preset]["css_areas"] using _parse_css_areas(...)[1], compares both zones_data and debug_zones counts and position sets against those expected positions, and raises ValueError with layout_preset, raw css_areas, expected positions, actual zone/debug positions, and counts.
Scope check: the guard is a strict prefix to the existing build_layout_css(...) and _compute_per_zone_geometry(...) calls. The diff for this file only adds the earlier u1 placeholder block plus this u2 guard; there are no changes to _apply_frame_override_to_unit, _run_step12_ai_repair, layout preset definitions, or the normal mapper success path in the inspected diff.

FINAL_CONSENSUS: NO
diff_summary:
In tests/phase_z2/test_compute_per_zone_geometry.py, appended one helper plus one new test below the existing test_fr_default_single_returns_full_body. No existing test, import, or fixture was touched (the four pre-existing mismatch / unknown-position raises tests remain green so the issue body's _compute_per_zone_geometry invariant test request is satisfied for both raise sites and the new success shape).
_placeholder_zone(position) — local helper mirroring the IMP-86 u1 placeholder zones_data record shape at src/phase_z2_pipeline.py:4459-4469:
content_weight.score == 0 ensures the placeholder does NOT steal weight from the surviving normal zone — same semantic as the production code.
min_height_px=100 matches DEFAULT_ZONE_MIN_HEIGHT_PX (src/phase_z2_pipeline.py:145) for parity with _zone(...) helper already in the file.
test_horizontal_2_normal_plus_placeholder_preserves_R2_cardinality — covers the bug scenario in the issue body at the helper level:
Builds zones = [_zone("top", 1.0), _placeholder_zone("bottom")] and matching debug_zones = [{"position": "top"}, {"position": "bottom"}].
Calls build_layout_css("horizontal-2", zones) (same path as the production FitError handler at src/phase_z2_pipeline.py:5030).
Asserts layout_css["areas"] == '"top" "bottom"' (R-source for _compute_per_zone_geometry at :1494), len(heights_px) == 2, len(widths_px) == 1.
Asserts heights_px[1] == 100 (placeholder gets min_height_px, no remaining-share inflation) and heights_px[0] + heights_px[1] + GRID_GAP == SLIDE_BODY_HEIGHT (= 585; full body conservation).
Calls _compute_per_zone_geometry(layout_css, debug_zones, GRID_GAP) and asserts len(per_zone) == 2, [pz["position"] for pz in per_zone] == ["top", "bottom"], height/width per zone matches layout_css["heights_px"] / SLIDE_BODY_WIDTH.
why this satisfies u3:
"Unit coverage for horizontal-2 normal-plus-placeholder geometry" — direct first-class assertion.
"heights_px / debug_zones / per_zone cardinality stays at R=2" — all three lengths asserted (len(layout_css["heights_px"]) == 2, len(debug_zones) == 2 by construction, len(per_zone) == 2).
The existing four raises tests (heights_px, widths_px, unknown_position) continue to cover the broken-build mismatch path the issue body asked to keep green.
why u1+u2 are not retested here:
u1's placeholder append is a runtime-loop edit, not directly addressable from a _compute_per_zone_geometry unit test — its real-pipeline coverage lives in u4 (the integration test).
u2's pre-build invariant guard is also a runtime-call-site edit; the same u4 integration test reaches the guarded build_layout_css call. u3 deliberately focuses on the helper invariant per the Stage 2 plan ("Unit coverage for horizontal-2 normal-plus-placeholder geometry").
test results (scope: tests/phase_z2/test_compute_per_zone_geometry.py only):
6 pre-existing tests stay green + the new u3 test passes. No regression in the existing 4 mismatch/raises tests. No edit outside tests/phase_z2/test_compute_per_zone_geometry.py.
scope guardrails honored:
No edit to src/phase_z2_pipeline.py (u1/u2 already landed in Rounds #1 and #2).
No edit to AI router, frame override semantics, layout preset catalog.
No new fixtures under tests/phase_z2/fixtures/ and no new tests/fixtures/ root (per tests/CLAUDE.md F-5 convention).
No sample MDX referenced from this unit (u4 handles the integration sample reference per Stage 2 plan).
No-hardcoding: assertions derive from build_layout_css output + SLIDE_BODY_WIDTH / SLIDE_BODY_HEIGHT / GRID_GAP constants exported by the production module; nothing is bytes-pinned.

follow_up_issue_candidates: none for this unit (u3 fully landed within scope-lock).

- "heights_px / debug_zones / per_zone cardinality stays at R=2" — all three lengths asserted (`len(layout_css["heights_px"]) == 2`, `len(debug_zones) == 2` by construction, `len(per_zone) == 2`).
- The existing four raises tests (`heights_px`, `widths_px`, `unknown_position`) continue to cover the broken-build mismatch path the issue body asked to keep green.
**why u1+u2 are not retested here**:
- u1's placeholder append is a runtime-loop edit, not directly addressable from a `_compute_per_zone_geometry` unit test — its real-pipeline coverage lives in u4 (the integration test).
- u2's pre-build invariant guard is also a runtime-call-site edit; the same u4 integration test reaches the guarded `build_layout_css` call. u3 deliberately focuses on the helper invariant per the Stage 2 plan ("Unit coverage for horizontal-2 normal-plus-placeholder geometry").
**test results (scope: tests/phase_z2/test_compute_per_zone_geometry.py only)**:
```
$ python -m pytest tests/phase_z2/test_compute_per_zone_geometry.py -q
....... [100%]
7 passed in 0.07s
```
6 pre-existing tests stay green + the new u3 test passes. No regression in the existing 4 mismatch/raises tests. No edit outside `tests/phase_z2/test_compute_per_zone_geometry.py`.
**scope guardrails honored**:
- No edit to `src/phase_z2_pipeline.py` (u1/u2 already landed in Rounds #1 and #2).
- No edit to AI router, frame override semantics, layout preset catalog.
- No new fixtures under `tests/phase_z2/fixtures/` and no new `tests/fixtures/` root (per `tests/CLAUDE.md` F-5 convention).
- No sample MDX referenced from this unit (u4 handles the integration sample reference per Stage 2 plan).
- No-hardcoding: assertions derive from `build_layout_css` output + `SLIDE_BODY_WIDTH` / `SLIDE_BODY_HEIGHT` / `GRID_GAP` constants exported by the production module; nothing is bytes-pinned.
**remaining_units**: [u4, u5]
**follow_up_issue_candidates**: none for this unit (u3 fully landed within scope-lock).
DO NOT commit / push (per orchestrator stage 3 contract — Gitea comment is the deliverable).
u3 is correct. In D:\ad-hoc\kei\design_agent\tests\phase_z2\test_compute_per_zone_geometry.py, the new _placeholder_zone(...) helper and test_horizontal_2_normal_plus_placeholder_preserves_R2_cardinality cover the horizontal-2 mapper-success plus placeholder geometry contract. The test asserts the preset areas remain "top" "bottom", heights_px stays at R=2, widths_px stays at C=1, the placeholder receives its min height without stealing content weight, body height is conserved with GRID_GAP, and _compute_per_zone_geometry(...) returns two zones with top/bottom positions and full slide-body width.
Source cross-check: the helper mirrors the geometry-relevant fields from the u1 production placeholder in D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py lines 4459-4468: template_id="__empty__", empty slot_payload, content_weight={"score": 0}, assignment_source="imp86_u1_adapter_needed", section_assignment_override=False, and provisional. The fixed test value min_height_px=100 matches the existing test helper baseline and is sufficient for the helper-level invariant being verified. Existing mismatch/unknown-position geometry tests in the same file remain green.
Scope check: this unit only changes tests/phase_z2/test_compute_per_zone_geometry.py; no production code was changed in u3. git diff --numstat reports 60 0 for this test file, so I verified the actual diff shape rather than relying on the claimed line count.

diff_summary:
New tests/phase_z2_ai_fallback/test_reject_override_geometry_invariant.py (Stage 2 plan target file). Two @pytest.mark.integration-marked tests + one stub helper + module docstring. No existing test, fixture, or source file was touched.
_stub_router_short_circuit() — MagicMock(return_value=None) AI-router stand-in. Returning None makes gather record (ai_called=False, skip_reason='router_short_circuit') per src/phase_z2_ai_fallback/step12.py:210-213. Asserting that pair on the reject record is the gather-side proof the router was actually invoked — distinct from the earlier-gate skips (not_provisional / route_not_ai_adaptation:<hint>) which would indicate the router was NEVER reached (the IMP-86 pre-fix failure mode where the pipeline crashed at _compute_per_zone_geometry BEFORE Step 12 fired).
test_integration_reject_override_reaches_step12_without_value_error(tmp_path, monkeypatch) — primary u4 coverage. Drives the issue body scenario verbatim:
Skips if samples/mdx_batch/03.mdx missing (mirrors tests/test_phase_z2_section_assignment_override.py:453-454 precedent).
Isolates run output: monkeypatch.setattr(pz2, "RUNS_DIR", tmp_path / "runs") (same pattern as tests/test_phase_z2_section_assignment_override.py:457).
Patches src.phase_z2_ai_fallback.step12.route_ai_fallback to the stub (no env / settings dependency).
Calls pz2.run_phase_z2_mvp1(_SAMPLE_MDX_PATH, run_id="imp86_u4_reject_override_integration", override_frames={"03-2": "bim_dx_comparison_table"}) — the exact CLI scenario from the issue body fresh repro 2026-05-22.
Asserts four guardrails from the Stage 2 plan:
G1 step12_ai_repair.json present — pre-IMP-86 this artifact was MISSING because the pipeline crashed at _compute_per_zone_geometry ValueError BEFORE Step 12 fired.
G2 provisional reject unit reached the AI router — provisional=True, route_hint='ai_adaptation_required' (IMP-47B u1 reject→AI map), skip_reason='router_short_circuit', ai_called=False, error=None, router.assert_called(). The _apply_frame_override_to_unit reject-judgment promotion at src/phase_z2_pipeline.py:1199-1208 is the upstream cause of the provisional flip.
G3 pipeline reached Step 20 — step20_slide_status.json presence is the strongest "no heights_px ValueError mid-pipeline" signal (pre-fix crash was mid-Step 7 layout build, well before Step 20).
G4 debug.json adapter_needed marker — adapter_needed_count >= 1 AND adapter_needed_units contains 03-2. This proves the u1 placeholder zone did NOT silently shadow the authoritative adapter signal (the placeholder is an additive zone slot; adapter_needed_units remains the source-of-truth surface).
test_integration_default_path_no_override_no_regression(tmp_path, monkeypatch) — Stage 2 regression sub-test. Same isolated runs dir + same patched router, but NO override_frames. Asserts step12_ai_repair.json + step20_slide_status.json both present, proving the u1 placeholder + u2 invariant guard are no-ops when the mapper succeeds for every unit (default mdx03 path; FitError branch is not entered).
why this satisfies u4:
Stage 2 plan target file (tests/phase_z2_ai_fallback/test_reject_override_geometry_invariant.py) created with the exact two integration tests prescribed.
Issue body guardrails fully covered:
"mdx03 reject override → AI 호출 도달: step12_ai_repair.json 생성 확인" → G1.
"ai_called=True 또는 의미 있는 skip_reason 명시" → G2 (skip_reason='router_short_circuit' is the explicit "router reached and returned None" signal — meaningful per Stage 2 unresolved-question resolution).
"mdx03 default (use_as_is path) 회귀 X" → second test.
AI isolation contract preserved: router patched to deterministic None-returning stub; no network / API / model dependency.
No hardcoding (RULE 7): test reads pipeline artifacts; only the deliberate --override-frame template_id bim_dx_comparison_table (the issue body's exact reproducer) and the section ID 03-2 (the issue body's exact target unit) are pinned.
Scope-locked: only the prescribed test file changed; production source untouched.
AI model id 404 (claude-opus-4-6-20250415) — already documented as out-of-scope in Stage 1 exit report (separate model-ID-validation track, P1 per issue body).
Per-placeholder telemetry refinement (adapter_needed=True / mapper_fit_error on the placeholder records themselves) — covered by remaining u5, in scope.
Integration coverage for non-mdx03 reject scenarios (e.g., mdx02 / mdx04 + reject override) — not raised by issue body; would be a generalization axis only if a non-mdx03 sample exhibited the same FitError-on-override pattern.

u4 is not correct as landed. The new integration file is present at D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_reject_override_geometry_invariant.py and it does drive the intended mdx03 reject override path far enough to produce step12_ai_repair.json and step20_slide_status.json. The Step 12 assertions also confirm the provisional 03-2 reject unit reaches the stubbed router and records skip_reason='router_short_circuit' with ai_called=False.
The failure is in the debug telemetry assertion. The test asserts debug.get("adapter_needed_count", 0) >= 1, but write_debug_json(...) writes slide status under the nested debug["slide_status"] key, not as top-level debug["adapter_needed_count"]. The run output confirms the actual slide status has adapter_needed_count = 1, and src/phase_z2_pipeline.py computes that value in compute_slide_status(...); however the debug artifact shape at write_debug_json(...) nests it as slide_status. The first u4 test therefore fails with got None, so the unit cannot be accepted.

[Claude #7] Stage 3 code-edit Round #5 — IMP-86 u4 (rewind fix)
Executing unit: u4
**rewind_context**: Codex #6 rejected u4 because the Guardrail 4 debug.json assertion read `debug["adapter_needed_count"]` at the top level, but `write_debug_json` (`src/phase_z2_pipeline.py:3254-3292`) nests the `compute_slide_status` payload (`src/phase_z2_pipeline.py:2939-3128`) under `debug["slide_status"]`. The actual key is `debug["slide_status"]["adapter_needed_count"]` (= 1 in the run), so the test asserted on `None` and failed. Pipeline behavior was correct; only the test's path expression was wrong.
**unit_executed**: u4
**files_changed**:

Error messages updated to reference the `slide_status.*` paths so future failures point at the correct key.
- Added a 4-line comment block citing `write_debug_json` and `compute_slide_status` line ranges to lock the schema upstream-of-the-assert and prevent regression to the wrong key.
- Guardrails 1–3 unchanged (Step 12 audit artifact, router_short_circuit, Step 20 reach). `test_integration_default_path_no_override_no_regression` unchanged.

Run-side telemetry from the integration test confirms upstream behavior was already correct pre-fix:
```
adapter : zone--bottom ['03-2'] → bim_dx_comparison_table FitError → adapter_needed (skip render)
zones : heights [227, 344] px, ratios [0.388, 0.588]
status : PASS
adapter_needed_count = 1
```
**remaining_units**: [u5]
u5 = telemetry fields on placeholder/debug records exposing `adapter_needed`, `mapper_fit_error`, and provisional state on the u1 placeholder zones_data/debug_zone records (without changing `adapter_needed_units` semantics). Scope per Stage 2 plan: `src/phase_z2_pipeline.py` only, ~20 lines, validated via the existing u4 integration test surface.
**follow_up_issue_candidates**:
- AI model id 404 (`claude-opus-4-6-20250415`) — still out of scope per Stage 1 / Stage 2 exit reports; P1 model-id-validation track candidate.
**scope_lock_check**: assertion-path fix only. No change to AI router, frame override semantics, `adapter_needed_units` schema, layout preset catalog, or `_apply_frame_override_to_unit`. `feedback_ai_isolation_contract` preserved (no auto frame swap, frame visual preserved, MDX 무손실). `feedback_factual_verification` honored — schema verified against the actual debug.json the pipeline writes, not assumed.
**guardrails_passed**:
- AI isolation: u4 fix is test-only; AI hook untouched.
- 하드코딩 금지: process verified, assertion now follows real `write_debug_json` shape; no artifact patch.
- Phase Z spacing: no shrink; layout preset / R-cardinality unchanged.
- Auto pipeline first: no review_required / review_queue gate introduced.
- 1 commit = 1 decision unit: u4 fix only; u5 deferred to next round.
**commit_sha**: pending (Stage 3 round-end, do not commit per stage rules).
u4 is correct as repaired. The integration test now reads adapter telemetry from debug["slide_status"], matching the upstream debug schema: compute_slide_status(...) emits adapter_needed_count and adapter_needed_units, and write_debug_json(...) nests that payload under the top-level slide_status key. The previous failed assertion against top-level debug["adapter_needed_count"] is gone.
The targeted verification passed. The reject override integration produced step12_ai_repair.json, confirmed the provisional 03-2 reject unit reached the stubbed router with skip_reason="router_short_circuit" and ai_called=False, reached step20_slide_status.json, and asserted the adapter-needed marker at debug["slide_status"]["adapter_needed_count"] plus debug["slide_status"]["adapter_needed_units"]. The default mdx03 path regression test also passed.
u5 is still not complete in this verified round. The current source diff still states that telemetry fields (adapter_needed / mapper_fit_error) land in IMP-86 u5, and the u4 test comments likewise say u5 will add finer per-placeholder telemetry. This round changed only the integration test assertion path, so Stage 3 should continue to the remaining implementation unit.

[Codex #7] Stage 3 code-edit verification - IMP-86 u4 rewind fix
Verified only the single executed unit: u4.
u4 is correct as repaired. The integration test now reads adapter telemetry from `debug["slide_status"]`, matching the upstream debug schema: `compute_slide_status(...)` emits `adapter_needed_count` and `adapter_needed_units`, and `write_debug_json(...)` nests that payload under the top-level `slide_status` key. The previous failed assertion against top-level `debug["adapter_needed_count"]` is gone.
The targeted verification passed. The reject override integration produced `step12_ai_repair.json`, confirmed the provisional `03-2` reject unit reached the stubbed router with `skip_reason="router_short_circuit"` and `ai_called=False`, reached `step20_slide_status.json`, and asserted the adapter-needed marker at `debug["slide_status"]["adapter_needed_count"]` plus `debug["slide_status"]["adapter_needed_units"]`. The default mdx03 path regression test also passed.
`u5` is still not complete in this verified round. The current source diff still states that telemetry fields `(adapter_needed / mapper_fit_error)` land in IMP-86 u5, and the u4 test comments likewise say u5 will add finer per-placeholder telemetry. This round changed only the integration test assertion path, so Stage 3 should continue to the remaining implementation unit.

Hoist _fit_error_str = str(e) and _unit_provisional = bool(getattr(unit, "provisional", False)) so the same FitError message + provisional state land identically on adapter_needed_units[i].fit_error, zones_data[i].mapper_fit_error, and debug_zones[i].mapper_fit_error.

[Claude #8] Stage 3 code-edit Round #6 — IMP-86 u5 (placeholder telemetry)
Executing unit: u5
**unit_executed**: u5 — telemetry fields on placeholder zones_data + debug_zone records expose adapter_needed, mapper_fit_error, and provisional state while preserving adapter_needed_units.
**files_changed**:

DO NOT commit or push. The Gitea comment IS the deliverable.
u5 is correct. In D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py, the mapper FitError handler now hoists _fit_error_str = str(e) and _unit_provisional = bool(getattr(unit, "provisional", False)), keeps adapter_needed_units on the same authoritative schema, and adds the per-record telemetry to both the placeholder zones_data record and the matching debug_zones record: adapter_needed=True, mapper_fit_error=_fit_error_str, and provisional=_unit_provisional.
The integration assertion for u5 is also present in D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_reject_override_geometry_invariant.py. Guardrail 5 reads the generated debug.jsonzones[] entry for source section 03-2 and verifies exactly the telemetry surface required by u5: adapter_needed is True, mapper_fit_error is a non-empty string, and provisional is True. This verifies the debug-zone consumer surface while Guardrail 4 still verifies debug["slide_status"]["adapter_needed_units"], so the authoritative adapter list was not replaced or drifted.
The targeted verification passed. I did not run full pytest because the current stage explicitly says to verify only the single unit executed in this turn and not to run full pytest unless required.

[Codex #8] Stage 3 code-edit verification - IMP-86 u5
Verified only the single executed unit: u5.
u5 is correct. In `D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py`, the mapper `FitError` handler now hoists `_fit_error_str = str(e)` and `_unit_provisional = bool(getattr(unit, "provisional", False))`, keeps `adapter_needed_units` on the same authoritative schema, and adds the per-record telemetry to both the placeholder `zones_data` record and the matching `debug_zones` record: `adapter_needed=True`, `mapper_fit_error=_fit_error_str`, and `provisional=_unit_provisional`.
The integration assertion for u5 is also present in `D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_reject_override_geometry_invariant.py`. Guardrail 5 reads the generated `debug.json` `zones[]` entry for source section `03-2` and verifies exactly the telemetry surface required by u5: `adapter_needed is True`, `mapper_fit_error` is a non-empty string, and `provisional is True`. This verifies the debug-zone consumer surface while Guardrail 4 still verifies `debug["slide_status"]["adapter_needed_units"]`, so the authoritative adapter list was not replaced or drifted.
The targeted verification passed. I did not run full pytest because the current stage explicitly says to verify only the single unit executed in this turn and not to run full pytest unless required.

Phase Z2 + AI fallback scope: python -m pytest tests/phase_z2/ tests/phase_z2_ai_fallback/ -q → 544 passed in 66.28s.

Pre-existing mismatch-raises tests in test_compute_per_zone_geometry.py remain green (legacy invariant unchanged).
■ Hardcoding audit (RULE 7 / no-hardcoding)
src/phase_z2_pipeline.py placeholder builds from unit.frame_template_id / unit.source_section_ids / unit.title / unit.frame_id etc. — all CompositionUnit-derived. No MDX 03/04/05 literal, no frame-id literal.
assignment_source="imp86_u1_adapter_needed" and skipped_reason="imp86_u1_adapter_needed_mapper_fit_error" are process-axis markers (issue-id tag), not sample-content literals — consistent with prior IMP-* assignment_source patterns.
Test files reference samples/mdx_batch/03.mdx + "03-2" — allowed under tests/CLAUDE.md F-5 fixture convention. src/** runtime path stays sample-free.
■ Guardrail compliance
AI isolation contract — frame preserved, no auto frame swap. Reject path still routes through AI router (Guardrail 2); placeholder is a render-side cardinality sentinel only (template_id="__empty__" short-circuits render_slide).
adapter_needed_units schema unchanged — Guardrail 4 still validates the authoritative slide_status.adapter_needed_units list; Guardrail 5 reads the new per-record telemetry from debug.jsonzones[] without changing the legacy channel.
Phase Z spacing — placeholder adds a zone (cardinality preserved at R), does not shrink (PZ-4 satisfied).
Auto pipeline first — no review_required gate introduced; FitError continues to record adapter_needed_units + new placeholder, downstream chooses automatically.
■ Issue body symptoms vs. post-fix evidence
"step12_ai_repair.json 미생성" → Guardrail 1: artifact present at runs/<id>/phase_z2/steps/step12_ai_repair.json (integration test passes).
"AI 호출 0" → Guardrail 2: provisional 03-2 record reaches router (stub router.assert_called() passes, gather records skip_reason='router_short_circuit' which is the explicit "router reached and returned None" surface per src/phase_z2_ai_fallback/step12.py:210-213).
"heights_px ValueError" → Guardrail 3: step20_slide_status.json present (pipeline reached final step without ValueError mid-flight).
"default path regression" → companion test test_integration_default_path_no_override_no_regression produces step12 + step20 artifacts on default mdx03 path (u1/u2/u5 are no-ops when mapper succeeds for every unit).
■ Decision: PASS — Stage 3 implementation matches Stage 2 plan (u1/u2/u3/u4/u5 all landed), no regression across 1066-test scope, no hardcoding violation, no AI-isolation contract drift, all 5 guardrails satisfied. Ready for commit-push gate.

D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py: FitError handler now preserves the failed unit's preset position with an __empty__ placeholder in zones_data, appends the matching debug_zone, keeps adapter_needed_units unchanged, adds per-record telemetry (adapter_needed, mapper_fit_error, provisional), and adds a pre-build layout invariant guard with preset/position/count diagnostics.
D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_reject_override_geometry_invariant.py: New integration coverage for mdx03 reject override reaching Step 12, no heights_px ValueError, placeholder telemetry in debug.json, and default-path regression.

AI isolation contract preserved: no AI-path or frame-swap logic changed; Step 12 router reach is tested with a deterministic stub.
Adapter contract preserved: authoritative slide_status.adapter_needed_units remains unchanged while placeholder records expose additive telemetry.
Phase Z spacing direction preserved: the fix adds a placeholder zone to preserve grid cardinality rather than dropping/shrinking the failed zone.
The pre-existing _compute_per_zone_geometry mismatch-raises behavior remains green via the existing geometry test file.

FINAL_CONSENSUS: YES
AI model id 404 (claude-opus-4-6-20250415) — explicitly out of scope per Stage 1 (out_of_scope: "separate model-ID-validation track"). The issue body itself flagged this as P1. Not opened this round; recommend tracking as a separate IMP issue under model-validation axis if not already filed.
No new follow-up axes discovered during Stage 2~5; no other unresolved items.
📌scope discipline
Only 3 files in the IMP-86 commit (src/phase_z2_pipeline.py, tests/phase_z2/test_compute_per_zone_geometry.py, new tests/phase_z2_ai_fallback/test_reject_override_geometry_invariant.py).
.claude/settings.json and all other untracked working-tree items (.orchestrator/, data/, Front/..., templates/catalog/, templates/phase_z2/families/*, chromedriver/, etc.) intentionally left unstaged — out of IMP-86 scope.
RULE 7 hardcoding audit clean: no mdx03/03-2/04/05/bim_dx literal in src/; literals confined to fixture integration test.
📌labels
(no label change request — defer to maintainer convention)
📌close decision
CLOSE — issue scope fully covered, all guardrails PASS, remote convergence verified, no remaining axis from issue body. AI model id 404 tracked as separate axis per Stage 1 out_of_scope contract.

Per-unit rationale:
u1: Primary fix at src/phase_z2_pipeline.py:4434-4448. FitError appends only to adapter_needed_units today; add parallel placeholder into zones_data (position, template_id, slot_payload={}, content_weight.score=0, min_height_px=DEFAULT_ZONE_MIN_HEIGHT_PX, adapter_needed=True, provisional mirror) and debug_zones. AI router (L4880) is position-keyed so placeholder remains addressable.
u2: Guard at src/phase_z2_pipeline.py:4937. Raise explicit invariant error with diagnostic context (positions + preset id + counts) so future regressions fail at the right boundary, not deep in _compute_per_zone_geometry.
u3: Extends tests/phase_z2/test_compute_per_zone_geometry.py with one horizontal-2 normal+placeholder test confirming length contract + per_zone shape.
u4: New tests/phase_z2_ai_fallback/ test invokes pipeline against samples/mdx_batch/03.mdx with --override-frame; asserts no ValueError + artifact presence + AI router reached + debug surface + default-path regression.
u5: Placeholder records expose mapper_fit_error on zones_data (AI apply path) and debug_zones (debug.json); AI gather is units-keyed so apply via position lookup remains valid.
Out of scope:
Rollback strategy:
Concentrated change in src/phase_z2_pipeline.py mapper-loop block + pre-build_layout_css guard — revert by removing placeholder append + invariant assertion. Tests stay as regression markers.

Per-unit rationale:
u1: Covers the root cause at src/phase_z2_pipeline.py FitError continue path. The failed unit's preset position must remain in zones_data/debug_zones so dynamic rows are computed for the same R as css_areas.
u2: Covers the requested explicit invariant/factual failure mode. It catches future shape drift at the pipeline boundary instead of the later geometry helper.
u3: Covers the direct _compute_per_zone_geometry invariant requested by the issue body. Existing tests already cover mismatch raises; this adds the success shape for the repaired case.
u4: Covers the guardrail scenario: mdx03 reject override, Step 12 artifact, AI called or explicit skip_reason, no ValueError, and no default-path regression.
u5: Covers observability without changing AI router, frame override, or adapter_needed_units semantics. It gives debug.json/step artifacts a factual reason for the placeholder.

u2 is correct. In
D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py, the pre-build layout invariant guard is inserted immediately before the existingbuild_layout_css(...)call at lines 4998-5030. It derives the expected zone positions fromLAYOUT_PRESETS[layout_preset]["css_areas"]using_parse_css_areas(...)[1], compares bothzones_dataanddebug_zonescounts and position sets against those expected positions, and raisesValueErrorwithlayout_preset, rawcss_areas, expected positions, actual zone/debug positions, and counts.Scope check: the guard is a strict prefix to the existing
build_layout_css(...)and_compute_per_zone_geometry(...)calls. The diff for this file only adds the earlier u1 placeholder block plus this u2 guard; there are no changes to_apply_frame_override_to_unit,_run_step12_ai_repair, layout preset definitions, or the normal mapper success path in the inspected diff.=== EVIDENCE ===

The default mdx03 path regression test also passed.u5is still not complete in this verified round. The current source diff still states that telemetry fields(adapter_needed / mapper_fit_error)land in IMP-86 u5, and the u4 test comments likewise say u5 will add finer per-placeholder telemetry. This round changed only the integration test assertion path, so Stage 3 should continue to the remaining implementation unit.=== EVIDENCE ===

D:\ad-hoc\kei\design_agent\tests\phase_z2_ai_fallback\test_reject_override_geometry_invariant.py. Guardrail 5 reads the generateddebug.jsonzones[]entry for source section03-2and verifies exactly the telemetry surface required by u5:adapter_needed is True,mapper_fit_erroris a non-empty string, andprovisional is True. This verifies the debug-zone consumer surface while Guardrail 4 still verifiesdebug["slide_status"]["adapter_needed_units"], so the authoritative adapter list was not replaced or drifted.The targeted verification passed. I did not run full pytest because the current stage explicitly says to verify only the single unit executed in this turn and not to run full pytest unless required.
