Comparison Target

• Source visual truth: /var/folders/sn/2jgcj5r95qq3t4l_7tzjh2gh0000gn/T/codex-clipboard-18484c1f-bc43-43a1-a329-791cb5605ff4.png and /var/folders/sn/2jgcj5r95qq3t4l_7tzjh2gh0000gn/T/codex-clipboard-1ff72f24-c84b-4b6a-94eb-4ced9a04bd4d.png.
• Implementation screenshot: /private/tmp/internal-dimension-lines-preview.png.
• Viewport: 1280 × 720.
• State: local scene route after clicking 2D and waiting 2.5 seconds; 3D remained selected and the scene remained on its loading indicator.
• Intended state: internal dimension baselines, witness lines, ticks, and values render clear of the wall, and enclosed perimeter doors receive room-side width dimensions.

Full-view Comparison Evidence

• The source screenshots show internal values while their linework is collapsed onto the host walls, making the strings read as detached text.
• The larger left perimeter door has no room-side width dimension in the source state.
• The implementation screenshot could not be compared at the same scene state because the local scene did not finish loading.

Focused-region Comparison Evidence

• Source: the horizontal internal strings contain values such as 0.5m, 0.9m, 4.9m, and 3.5m, but the intended parallel baseline and extension linework is not visibly separated from the wall.
• Generated implementation geometry now places automatic internal baselines at 0.55 m from their witness origins rather than explicitly pinning them at 0 m.
• Generated plans now include room-side opening chains for enclosed perimeter walls in all four orientations, including a left-side door.
• A same-state rendered focused comparison is blocked by the local loading state.

Findings

• [P0] Browser-rendered implementation evidence unavailable. Location: local editor preview. Evidence: the captured implementation contains only the loading indicator; clicking 2D leaves 3D selected. Impact: final screen-space line visibility, collisions, and door-width placement cannot be visually accepted. Fix: restore a working local scene preview and recapture the reported room in 2D.

Required Fidelity Surfaces

• Fonts and typography: source labels remain unchanged by this fix; post-fix rendered typography is blocked from inspection.
• Spacing and layout rhythm: geometry tests verify the internal baseline clearance is restored to 0.55 m; pixel-level rhythm is blocked from inspection.
• Colors and visual tokens: no color or token changes were made; rendered contrast is blocked from inspection.
• Image quality and asset fidelity: no image assets are involved.
• Copy and content: dimension values remain generated from the same measurements; the missing perimeter-door width is now included.

Comparison History

• Earlier P0: internal baseline coordinates were explicitly equal to witness coordinates, overriding offsetDistance and collapsing lines onto walls.
• Fix: preserve omitted automatic baselines so the renderer applies the configured offset; add enclosed room-side opening chains for perimeter walls.
• Post-fix evidence: SVG renderer regression asserts a 0.55 m automatic baseline, and planner regressions cover top, right, bottom, and left perimeter doors. Browser-rendered evidence remains blocked.

Implementation Evidence

• Focused dimension, wall, floor-plan, and registry tests: 61 passed, 0 failed.
• Nodes package build: passed.
• Editor package type-check: blocked by the unrelated missing resolveFloorplanExportViewport export referenced by floorplan-export.test.ts.
• Biome check: passed.
• Git diff whitespace check: passed.
• Browser console warnings/errors: none reported.

Implementation Checklist

• Restore the local editor preview.
• Reopen the reported room in 2D.
• Confirm each internal string has a visible parallel baseline, witness lines, and ticks.
• Confirm the large left-side door displays its room-side width dimension.

Follow-up Polish

• Reassess internal line contrast only after the corrected geometry can be seen in the target scene.

final result: blocked
