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 (issue text: "현재 horizontal-2 / vertical-2 만 dynamic — 다른 preset 도 dynamic").
Guardrail = Kei build_containers_type_b (page_structure) 회귀 X + zone-level ratio 변경 시 Step 8 trace 설명 가능.

Before (Round #3) vs After (Round #4)
git rev-parse --short HEAD=201099e(unchanged from Rounds #1–#3).git diff HEAD -- src/phase_z2_pipeline.py src/space_allocator.py tests/phase_z2/→ empty (no implementation movement since Round #3 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)
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, {z1..z4: {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 |
Test evidence — PR 1 lock-in tests 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 (top-1-bottom-2 / top-2-bottom-1 / left-1-right-2 / left-2-right-1 / grid-2x2) must be dynamic. Currently 0/5 dynamic. PR 1 (HEAD) ships the foundation only — col-axis solver, unified per-zone geometry mapper, length-locked widths/widths_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 code comments at lines 1219–1220.
Guardrail check
build_containers_type_b / page_structure paths untouched — git diff HEAD -- src/space_allocator.py is empty since PR 1 merge. No regression detected.
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 |
| build_containers_type_b guardrail | preserved | preserved (no diff) | OK |
| Step 8 trace explainability | required | partial — zone_widths_px_planned ships but only populated on rows/cols dynamic returns |
partial |
| Override path strict ValueError | PR 2 contract | still warn-and-fallthrough | NOT MET |
Conclusion
B-4 issue scope is NOT closed by HEAD 201099e. PR 1 is a deliberately-scoped foundation lock; the topology dispatch + override strict-mode promotion for the 5 listed presets is the binding deliverable of PR 2 (with single deferred to PR 3). Four consecutive verification rounds (Claude #1–#3 + Codex #1–#3 + this round) agree on this AS-IS reading; no implementation movement has occurred between rounds.
