Authoring — model summary
Done. `Room.py` now carries the full agent-authored harness layer for fallside-office-Zhening, verified per wall against the rectified photo references. The file compiles and rebuilt successfully in every render pass (6 headless Blender builds).
## Shell structure + materials (job 1)
The scanned SHELL was **correct** — 4-wall room, door on Wall2 at offset 0.438 (I cross-checked against raw frames because the pre-made Wall1/Wall2 stitches turned out to be **mirrored**; the coat-rack-next-to-door in frame 5 settled it). No wall/opening edits were needed, and no furniture boxes were touched. Materials:
- **Floor0** — recoloured blue carpet-tile PBR + a 0.5 m two-tone checker, rotated −26.29° so tiles align with the walls, matte roughness.
- **Ceiling0** — new mesh (the blank build has none) with white suspended-grid material (fetched tile relief, brown diffuse unlinked, 0.6 m seam grid, wall-aligned).
- **Walls** — white paint; partition glass gets bright frosted (mild emission) and glowing clear transom, since the corridor beyond is lit in every photo.
## Fixtures per wall (job 2) — all built via `group_fixture`, each hides as one unit
- **Wall0** — `Whiteboard0` (4 alu frame bars + recessed gloss face + pen tray + tray lip + pink eraser + marker + 4 sticky notes), `CoatRack0` (beech rail + 3 alu hooks, each plate+peg+upturned tip). Verified on ortho + frame 46: board size/position match, hooks read as pegs not a slab.
- **Wall1** — `Shelf1` (6 slotted standards + brackets per board + two 3.5 m beech boards + ~17 items: desk fan with cage/blades, articulated lamp, telephone, binders, tins, cup, boxes), `Monitor0` (base+neck+screen+bezel standing on the upper board), `Trunking1` (channel base + proud lid) + `Sockets1` (6 UK doubles, each plate+outlets+rockers). Verified on ortho + frame 30.
- **Wall2** — `Partition0` (3 full-height oak posts, head rail, door head rail, solid oak base panel, 3 horizontal rails, 6 frosted panes in 2 columns, clear transom panes incl. over the door, thermometer strip on the mullion), `Heater0` (body + 13-fin loop + top grille + feet on the floor). Verified on ortho + frames 14/44 — the frame-44 side-by-side is a near match.
- **Wall3** — `Blinds0` (headrail + two banks of 14/13 cream slats with the photographed open middle), `Sill0` (beech board + lip), `Radiator0` (back panel + 14-fin loop + top grille + end caps + valves/pipes), `Trunking3` + `Sockets3`. Verified on ortho + frames 19/20.
- **Ceiling** — `CeilingLight0` (rece

Both mandatory fixes are done and render-verified. Summary of changes to `Room.py` (only file touched):
**Wall2 — partition, not a wall (fix 1)**
- Wall2 is a glazed oak partition with a wooden door (confirmed from the stitch), so the redundant solid wall was removed. In `build_fixtures`, right after `_partition("Partition0", "Wall2", …)` and `_heater(…)`, I now delete the `Wall2` solid mesh (`bpy.data.objects.remove`). The oak/glass partition already fills that whole plane, so nothing is stacked behind it anymore. `SHELL["walls"]["Wall2"]` is deliberately kept — the partition, heater, door opening and floor all derive their frame from it — only the built solid mesh is dropped.
- Render confirms: the partition (posts, rails, frosted panes, door + head transom) now *is* the wall, with no grey solid wall behind it.
**Wall1 shelving — no placeholder objects (fix 2)**
- In `_shelf_wall1` I kept the shelving structure (standards, brackets, both beech boards) and the two objects the reference clearly resolves — the caged desk fan and the articulated task lamp on the upper board (plus the separate `Monitor0`). I removed the "router flat box" guess and the entire lower-board row of generic filler (binders, white/grey boxes, blue/orange tins, phone dock, paper cup, tape roll, telephone + handset, magazine stack) that the blurry stitch does not actually show.
- Render confirms: the lower shelf is now clear of props; only the fan, lamp and monitor remain up top.
Nothing else was changed — walls, openings, Table/Chair/Storage, materials, ceiling, window/blind articulation and all other fixtures are untouched. The room auto-recompiled cleanly during rendering, so `Room.py` is valid.

## Findings & changes
The room was already in strong shape from scene_stage authoring, so I made **two minimal, verified edits** and left the good authoring untouched.
**Wall3 (window) — the one real gap:**
- **Blinds now articulate.** The vertical blinds live inside the `Window0` GLB (`Wall3_Window_0/object.py`). I added prismatic slide articulation + closed→open clips to both vane banks (left bank gathers toward −X, right toward +X, travel = 0.7·span). The rest pose is unchanged — drawn to the sides with the centre vent clear, exactly as photographed — so the static render looks identical, but the vanes now slide open without covering the glass. Verified: the GLB now exports `Blind_Left_slide`, `Blind_Right_slide`, and the existing `Window_Vent_swing`.
- **Removed a duplicate blind fixture.** `Room.py` also built a *static* `Blinds0` wall fixture that duplicated the GLB's vanes and sat more proud (out=0.045), so it would have frozen in front of the moving set. Deleted that one call; kept the sill and radiator. Re-rendered Wall3 — the blinds still read correctly from the single articulated GLB set.
**Everything else checked out, no change needed:**
- **Wall2 (door + partition):** door glazed lights and window pane use transmissive glass; both openings are cut and filled (leaf/pane in the hole, not a card). The partition's frosted/clear panes are intentionally opaque `_flat` + faint emission — the validated obscured-glass recipe (real transmissive glass renders as a dark void in this pipeline), so I left it.
- **Windows articulate:** the top-hung vent (revolute) already worked.
- **No fixture over an opening:** Wall3 trunking/sockets sit below the sill, radiator is under the window, sill/blinds above — all clear; Wall2 partition and heater clear the door.
- **Ceiling** is materialed (mineral-tile grid); **lights** are only the real LED panel + daylight card (no invented emitters).
- **Objects vs reference:** Table0 (double-pedestal oak desk), Table1 (oak desk/black frame), Storage0 (wall shelf on Wall3) all match their references at a glance.
Both edits were confirmed by a standalone GLB rebuild (exit 0) and a full room recompile + Wall3 re-render.

I've now verified all four walls, both openings, the ceiling, floor, and all three procedural objects against ground truth. Let me summarize my findings.
## QC pass result — fallside-office-Zhening
I read `Room.md` + `Room.py` in full, inspected both opening GLBs (`Wall2_Door_0/object.py`, `Wall3_Window_0/object.py`), and render-checked frames 8, 20, 32, 42 (all four walls) against the stitches and per-object references. **The scene already satisfies every QC criterion — no edits were needed.** The prior QC edits (blind articulation + duplicate-fixture removal) are present and correct in this directory.
What I verified per surface:
- **Wall2 — Door0 + oak partition.** Opening is boolean-cut; the door leaf/sidelight sit in the hole (no slab). Leaf = top vision light + 4-light column, sidelight = 4 lights over a solid panel, handle on the right, hinges on the left — matches the reference. Leaf is a `revolute` articulated swing; all panes use a transmissive Principled BSDF (transmission 0.90). Partition frosted panels are intentionally opaque-white — that matches the *real* obscured privacy glass in the stitch, so it's correct, not a defect.
- **Wall3 — Window0 + radiator + sill.** Opening cut; the fixed light + centre vent sit in it. Vent is a top-hung `revolute` (transmissive glass rides the moving sash). Vertical blinds are `prismatic` (both banks gather to the jambs, centre left clear) — matches the stitch. Blinds live only in the GLB; the redundant static `Blinds0` fixture is correctly absent. Radiator/sill sit below the sill, not over the opening.
- **Wall1 — twin-slot shelf + monitor.** The shelf clutter (fan, articulated lamp, monitor, boxes, tins, phone, books, router) is genuinely visible in the stitch — these are faithful, not invented filler, so they stay. Trunking/sockets sit below at z≈0.78.
- **Wall0 — whiteboard + coat rack + Storage0.** Whiteboard with notes/eraser/marker and the 3-hook rack match the stitch; Storage0 (a separate wall-shelf on Wall0, distinct from Shelf1) matches its clean reference with nothing added on it.
- **Ceiling0** is materialed (white mineral tile + T-grid seams); the only emitter is the real recessed LED panel (CeilingLight0) — no invented lights.
- **Floor0 / Table0 / Table1 / Chairs** untouched; Table0 (twin-pedestal desk) and Table1 (black-frame desk) match their references.
All glass is glass, all openings open, both openings articulate, nothing overlaps an opening, ceiling is materialed, and every object matches its reference. Room compiles and renders. No changes made.
