[Claude #5] Stage 6 — Verification Round #5
Re-read issue
Scope = build_layout_css 분기 확장 to top-1-bottom-2 / top-2-bottom-1 / left-1-right-2 / left-2-right-1 / grid-2x2 beyond the existing horizontal-2 / vertical-2 dynamic paths.
Guardrail = Kei build_containers_type_b (page_structure) 회귀 X + zone-level ratio 변경 시 Step 8 trace 설명 가능.
Before (Round #4) vs After (Round #5)
git rev-parse --short HEAD=201099e(unchanged from Rounds #1–#4).git diff HEAD -- src/phase_z2_pipeline.py src/space_allocator.py tests/phase_z2/→ empty (no implementation movement since Round #4 closed NOT VERIFIED).- Dirty/untracked worktree files are all outside the verifier scope (Z2 frame templates, samples, unrelated scripts).

AS-IS (HEAD = 201099e — PR 1 foundation lock)
Static evidence — dispatch is still rows / cols only (src/phase_z2_pipeline.py:1214–1221):
# ── Dynamic branch — topology dispatch (PR 1: rows / cols only) ──
if topology == "rows":
return _build_rows_dynamic(preset, zones_data, gap)
if topology == "cols":
return _build_cols_dynamic(preset, zones_data, gap)
# PR 2 will dispatch T / inverted-T / side-T-{left,right} / 2x2 here.
# PR 3 will dispatch single here.
return _build_fr_default(preset)
Override path (src/phase_z2_pipeline.py:1205–1212) still warn-and-fallthrough for non rows/cols presets (PR 1 lock — PR 2 promotes to strict ValueError).
Runtime probe — build_layout_css(preset, {zN: {content_weight:1.0, min_height_px:100}}):
| Preset | dynamic_rows | dynamic_cols | computation |
|---|---|---|---|
top-1-bottom-2 |
False | False | fr_default_from_preset |
top-2-bottom-1 |
False | False | fr_default_from_preset |
left-1-right-2 |
False | False | fr_default_from_preset |
left-2-right-1 |
False | False | fr_default_from_preset |
grid-2x2 |
False | False | fr_default_from_preset |
single |
False | False | fr_default_from_preset |
Return keys on the fallthrough path are length-locked (['areas', 'cols', 'computation', 'dynamic_cols', 'dynamic_rows', 'heights_px', 'ratios', 'raw_zone_layout', 'rows', 'width_ratios', 'widths_px']) — PR 1 foundation contract holds, but computation is the unmistakable signal that the dynamic solver did not run for any of the 5 target presets.
Test evidence — PR 1 lock-in still in place (tests/phase_z2/test_build_layout_css_pr1.py:145–154):
"""T-shape (top-1-bottom-2) falls through to fr_default in PR 1 …"""
result = build_layout_css("top-1-bottom-2", zones)
assert result["computation"] == "fr_default_from_preset"
Closing B-4 requires updating this assertion when PR 2 lands.
TO-BE (issue scope target)
All 5 listed presets must be dynamic. Currently 0/5 dynamic. PR 1 (HEAD) is the foundation lock — col-axis solver, unified per-zone geometry mapper, length-locked widths_px / width_ratios / dynamic_cols on every return path, retry gate (with retry_skipped_reason), and zone_widths_px_planned / zone_col_ratios_planned Step 8 trace fields. PR 2 (T / inverted-T / side-T-{left,right} / 2x2) + PR 3 (single) remain outstanding per the in-code TODO at src/phase_z2_pipeline.py:1219–1220.
Guardrail check
build_containers_type_b / page_structure paths untouched by PR 1; static grep confirms no edits to those call sites since 201099e. The trace surface added by PR 1 (zone_widths_px_planned, zone_col_ratios_planned, retry_skipped_reason) is present in src/phase_z2_pipeline.py:3550–3578 and 1621–1631, so the "zone-level ratio 변경 시 step08 trace 설명 가능" guardrail is satisfied for the foundation. It will need to be re-exercised once PR 2 turns on T / side-T / 2x2 dynamic paths.
Gaps vs Close
| Axis | Issue requirement | Current state | Gap |
|---|---|---|---|
| top-1-bottom-2 dynamic | required | fr_default fallthrough | NOT MET |
| top-2-bottom-1 dynamic | required | fr_default fallthrough | NOT MET |
| left-1-right-2 dynamic | required | fr_default fallthrough | NOT MET |
| left-2-right-1 dynamic | required | fr_default fallthrough | NOT MET |
| grid-2x2 dynamic | required | fr_default fallthrough | NOT MET |
| Kei build_containers_type_b 회귀 X | required | untouched | MET |
| Step 8 trace explainability | required | foundation fields present | MET (foundation only) |
Verdict
NOT VERIFIED for close. 5/5 target presets remain on the fr_default_from_preset fallthrough; PR 2 (T / inverted-T / side-T-{left,right} / 2x2) has not landed. PR 1 foundation (HEAD = 201099e) holds — col-axis solver, per-zone geometry mapper, retry gate, Step 8 trace fields all intact — but B-4 issue scope explicitly demands the dispatch promotion that PR 2 owns. Closing this issue requires shipping PR 2 (and PR 3 for single, if it is in scope), then updating tests/phase_z2/test_build_layout_css_pr1.py:145–154 from "falls through to fr_default" to the new dynamic assertions.
