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.

AS-IS (HEAD = 201099e — unchanged since Round #2)

Git state:

201099e feat(IMP-09): PR 1 — col-axis solver + per-zone geometry mapper + retry gate

git diff HEAD -- src/space_allocator.py src/phase_z2_pipeline.py → empty (no in-flight edits since Round #2).

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) is still warn-and-fallthrough for non rows/cols presets (PR 1 lock — PR 2 promotes to strict ValueError).

Runtime probe — build_layout_css(preset, zones) with each zone carrying {content_weight: 1.0, min_height_px: 100} for every zone-id present in the 5 + single topologies:

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

Test evidence — PR 1 tests still explicitly assert the unfinished state (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"

This is a PR 1 lock-in assertion. Closing B-4 requires updating it when PR 2 lands.

TO-BE (issue scope target)

All 5 listed presets must be dynamic; currently 0/5 are. PR 1 (HEAD) is the foundation lock — it delivers the col-axis solver, unified per-zone geometry mapper, length-locked widths/widths_ratios/dynamic_cols on every return path, the 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 code comments at lines 1219–1220.

Guardrail check

build_containers_type_b / page_structure paths untouched by PR 1; static grep on src/ shows them in space_allocator.py / block_assembler*.py / kei_client.py / pipeline.py / validators.py / fit_verifier.py / content_verifier.py / step_visualizer.py / html_generator.py / pipeline_context.py / block_reference.py — git diff HEAD -- src/phase_z2_pipeline.py src/space_allocator.py is empty so no regression risk introduced since 201099e.

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	satisfied (untouched)	OK
Step 8 trace ratio fields	required	landed (zone_widths_px_planned, zone_col_ratios_planned, per-zone variants)	OK

5 of 5 scope-axes still NOT MET. Foundation + guardrail axes are MET, but B-4 closure needs PR 2 (T / inverted-T / side-T-{left,right} / 2x2 dispatch). Three independent rounds (Claude #1+#2+#3, Codex #1+#2) agree.

Verdict

NOT VERIFIED for close. Issue must remain open pending PR 2 (the 5 listed presets) and PR 3 (single).

=== EVIDENCE === Commands run:

• git log --oneline -5 → HEAD = 201099e (PR 1)
• git status --short → no in-flight edits to src/phase_z2_pipeline.py or src/space_allocator.py
• git diff HEAD -- src/space_allocator.py src/phase_z2_pipeline.py → empty
• python -m pytest -q tests → 89 passed in 6.85s
• Runtime probe: python -c "from src.phase_z2_pipeline import build_layout_css; ..." for top-1-bottom-2 / top-2-bottom-1 / left-1-right-2 / left-2-right-1 / grid-2x2 / single

Files checked:

• D:\ad-hoc\kei\design_agent\src\phase_z2_pipeline.py (lines 1180–1221: override path + dynamic dispatch)

• D:\ad-hoc\kei\design_agent\src\space_allocator.py (no diff)

Verified facts:

• 5 of 5 listed presets return computation=fr_default_from_preset with dynamic_rows=False, dynamic_cols=False
• Single preset also returns fr_default (PR 3 scope per inline comment)
• horizontal-2 / vertical-2 dynamic paths preserved by PR 1 (covered by tests/phase_z2/test_build_layout_css_pr1.py with full fixtures)
• build_containers_type_b / page_structure paths untouched by PR 1
• Step 8 trace fields landed on PR 1 (zone_widths_px_planned, zone_col_ratios_planned, zone_width_px_planned, zone_col_ratio_planned)
