# LANE 10 — SITE 7: MONSTER ROBOT PARTY

*The level the whole game started as. Spec'd and executed by Fable, 2026-08-04.*

## The idea

Every other site is authored. This one is **imported from the real shop**. The live
storefront at `robotmonster.party/store/` is procedurally assembled from Postgres rows
(`virtual_rack`, `virtual_crate`, `virtual_rack_type*`, `virtual_crate_type` — the
wowplatter schema, now served by recordgod/storegod), and the game's sites are already
data. So Site 7 is not hand-placed: a converter reads the shop and emits a level.

`GET https://robotmonster.party/virtual/scene` returns the shop floor:

| | |
|---|---|
| room | 6.66 m × 9.51 m, 2.89 m ceiling |
| racks | 35 placed, across 21 archetypes |
| crates | 302, every one on a rack |
| labels | real: `HARD TRANCE`, `$12-$15 EURO/ITALO HOUSE`, `SOUND TRACKS, SPOKEN WORD & COMEDY` |
| stock | **22,049 records** across the bins (`n_items`) |

The rack archetype names (`wooden-rack-type-long`, `white-tub-3x3`, `chiu-long`) are the
same names as the GLBs in `3D-STORE/`, because both were generated from the same table.

## Why this is the best-fitting level in the game

The shop's schema **is** the cascade. `virtual_crate.rack_id` already says which rack
holds which bin, so `rack.supports = [its crates]` falls out of the data — knock a rack
and the real bins that really sit on it really go over. Nothing to author.

## Deliverables

### 1. Generic data-driven cascade *(`Main.gd`, small)*
Extend the `smashables` spec entry with two optional keys so a level can express support
without code: `"id"` (a name other entries can refer to) and `"supported_by"` (the id of
the piece holding this one up). Main builds in order, keeps `id -> Smashable`, and wires
`holder.supports.append(piece)`. Every existing level is unaffected.

### 2. `tools/import_store.py` — the converter
Fetches the live scene (`--url`, or `--offline <file>`), filters to the shop-floor space,
and emits `game/assets/store/shop_floor.json`:
- world-space rack positions, **re-centred** (the shop's origin is a corner; the game
  centres its bounds on 0)
- each crate placed by `rack_pos + rotate_y(crate_local, rack.rotation_y)`, carrying its
  real `label` and `n_items`
- archetype → game GLB + material mapping (tubs are `plastic`, timber racks `wood`,
  columns and aircon `steel`)
- crates spawn **frozen** and supported by their rack: they don't jitter at spawn (the
  stillness gate stays green) and they go live exactly when the rack does
- a **measured spawn point** — a grid scan for open floor, because a 6.66 × 9.51 room
  holding 35 racks has very little of it, and spawning inside a rack is not a level

Re-runnable: when the real shop is rearranged, re-run it and the level changes.

### 3. `Levels.record_store()` — the site
Loads the JSON and returns a normal Floorplan spec. Timber floor, white walls, the
brand's pink as accent. Added to `Levels.ORDER` as the seventh site.

## Gates
Headless smoke clean · `probe_levels` **7/7** at 0.00 m/s · `probe_overlap` CLEAN ·
the LANE9 probes still green. Plus `dev/probe_store.gd`: the site builds, the rack→crate
cascade is wired, and smashing one rack releases exactly its own bins.
