model op• Data kinds: कोई नहीं → simmodel (केवल arguments से तय होने वाला op — यह कोई image या data input नहीं लेता)
• Call: import fullseye as fs; fs.ledger.simcal_model(chain=None, knobs=None, scene=None, nuisance=None, noise=None, conditions=None, stochastic=None, label='model') -> 'dict' (implementation को सीधे call करना हो तो import simcal; simcal.simcal_model(chain=None, knobs=None, scene=None, nuisance=None, noise=None, conditions=None, stochastic=None, label='model') -> 'dict', registry से लेना हो तो opssimcal.get("simcal_model"))
simmodel बनाता है: ops की forward chain जिसके arguments इकाई व सीमा वाले knobs हैं, साथ में noise model।

chain — list of steps {"op": name, "args": {...}}; op is any registered fullseye op (e.g. "thin_film_reflectance") or a built-in stage ("stage:gain_offset", "stage:scale", "stage:radial_cos4", "stage:radial_poly", "stage:gaussian_blur", "stage:as_image", "stage:mc_sample"). Step 0 receives scene as its first argument (or nothing when scene is None), each later step the previous output.
knobs — list of dicts {"name", "step" (index or op name), "arg", "lo", "hi", "unit", "scale" ("linear" | "log"), "init", "prior" ((mean, sd) or None), "role" ("gain" | "offset" | None), "fixed" (value or None)}. A knob is bound to one argument of one step; init defaults to the middle of the range (geometric middle on a log scale).
conditions — optional list of {step: {arg: value}} (one output image per
condition: exposures, wavelengths, illumination angles). nuisance — names of knobs that are fitted but not of interest; label names the model in reports. noise / stochastic — see the module docstring.
The model is run once at the initial knobs and refused (ValueError) when a step is unknown, a knob names an argument its op does not take, two knobs bind the same argument, a range is empty or a log range is not positive, or the output is not a finite 2-D array. With no arguments: a demo model (chart -> cos^4 vignetting -> gain/offset, EMVA noise) with synthetic observations attached, ready for simcal_fit.
