THE BEAST — LEFT SIDE (photo sketch)

Four docked carts read from 44 photographs: LS air deck (compressor · heater · FRL) → CL meter deck (Coriolis · magmeter · AODD) → CR pump deck (2 pumps · reservoir · HMI) → RS head-tank wing (elevated tank · power tower) — scene read and authored by Fable 5, no external vision API

PHOTO SKETCH — read from photographs alone; no drawing, no measurement. Positions and sizes are photo estimates.

Photo sketch — how it was made

Every body below was authored from the photographs alone (blind experiment: no P&ID, no prior model, no measurements). Parametric recipes come from matsparts.py; positions are photo-read estimates (±0.1–0.2 m); sizes carry a stated reference. Tags are quoted only where a printed tag or brand was legible in a photo.

Looking methodcontact sheet, then zoom crops	All 44 photos on contact sheets first; then per-area zoom crops (PIL) to read nameplates, deck corner labels (LS / CL / CR / RS), printed pipe stencils and hang tags. 44/44 photos viewed; 26 studied full-res
Routed pipepipe_run	Polyline swept as cylinders with sphere elbows. Bore is a photo estimate (~1 in) — the photos print pipe SPEC stencils (e.g. 'SEG 5835 NACE') but no bores. traced runs drawn solid; occluded segments marked INFERRED in nodes.json
Valvesvalve_body / handwheel / check_valve	Bowtie body + flanges; red ring for red handwheels; NRV with flow cone. Placed only where a valve is actually visible. ~40 valve stations
Actuated & solenoidactuator / coil boxes	Hayward-type electric ball valve on CL top; ASCO brass, green-coil and large power solenoids where seen. 6 powered valves
Equipmentcustom assemblies over matsparts primitives	Compressor (tank + finned block), electric finned heater (LS-HE tag read), Coriolis + magmeter (E+H-type), AODD pump, 3 close-coupled pumps, gear-pump station in acrylic guard, FRL, reservoir + elevated head tank, 3 HMI/control panels, GPStrategies power tower. the five scoreable anchors: pump, compressor, exchanger, receiver(?), panel
Hosespipe_run, thin	The LS-CL aisle is bridged by flexible red air hoses + cables on a green bridge arm — drawn as sagging polylines; the black hose connection is INFERRED (ends not visible). 3 hoses

Scale basis: operator's "~2 m" (told, not measured) · California Air Tools compressor family length 0.66 m · 41 mm unistrut pixel scales. Runs the camera could not follow are drawn but marked INFERRED in beast_photosketch_nodes.json.
