Visual-review checklist (W18G)

Interior reads as the structural unit region targeted by the W18F base markers for L05B04 (target unit marker numbers carried verbatim from the payload).
Door anchor and window anchor markers reported by W18F are visible in their referenced positions.
Transient cues from the W18F payload appear as on-surface floor / window / edge cues only — never drawn back onto the base FP image overlay.
No person, no body, no corpse rendered. Only the room interior, fixtures, and the transient cues.
The base FP structural layout is respected; the generated background does not contradict the FP topology.

final smoke prompt

Create an interior background image matching the referenced base floor plan region; use the FP as layout guidance, not as a visible overlay. Render the room from a natural standing eye-level perspective. Do not render any person, body, or corpse — depict only the room interior, fixtures, and the transient floor/window/surface cues described below.

A low-angle cinematic shot looking through the gap of bedroom A door (8) onto a dark wooden floor inside bedroom A (3). A wet, dark red floor stain zone (23) spreads across the boards, with a distinct footprint trail (19) leading past the bed toward long closed window curtains (12) that drape down to the floor (18). Cool night-blue darkness leaks from the window.

Layout follows fp_l05_01. Low-angle view looking through bedroom A door (8) into private bedroom A (3) showing a red floor stain zone (23) and a footprint trail (19) leading toward the curtain-side floor evidence zone (18).

[background_prompt_region_appendix] Preview only — assembled deterministically from W18D payload.
Base FP image reference (layout / rooms / fixed anchors only): scripts_output/floor_plan_base_layout_image_smoke_slice_experiment/20260526_1500_0ab6ac/png/fp_l05_01.png
Do not redraw, relocate, or add transient overlay markers onto the base FP image; transient markers belong only in the background prose.
Target spatial units for this background:
  - #3 (private_bedroom_a) private bedroom A @ 10x10 rect [6,3,9,8]
Base markers visible on the base FP image:
  - #3 private bedroom A [base_structural_unit] @ 10x10 cell (7,5)
  - #8 bedroom A door [base_opening] @ 10x10 cell (6,5)
  - #12 bedroom A sliding window with curtains [base_opening] @ 10x10 cell (7,8)
Transient overlay markers to describe in the prose:
  - #18 curtain-side floor evidence zone [state_overlay_plot_cue] in unit 'private_bedroom_a' — overlay_hint: Depict a temporary floor evidence zone near the curtain side only when the selected background calls for it.
  - #19 footprint trail [state_overlay_plot_cue] in unit 'private_bedroom_a' — overlay_hint: Depict a temporary footprint trail across the bedroom floor only when the selected background calls for it.
  - #23 red floor stain zone [state_overlay_plot_cue] in unit 'private_bedroom_a' — overlay_hint: Depict a temporary red floor stain beside the bed area only when the selected background calls for it.
