"""Tangibool evaluator (decision model).

Generated deterministically from the validated Boolean model; it evaluates exactly that
model. It does not establish that the model is a complete, legal, or safe statement of a
real-world rule, and evaluating examples does not verify the rule.

Logic digest: 91a23ad742858028ac5d50195304c533a2ef7b50d25f63acb5fb8f991c557419
Assumptions digest: d58ee1ad38e23e5093e4baa1047b5ae70d6972e08f555e34ac3fa16df63c4a78

Inputs (dict keys, declared order) and generated parameter names:
    'member' -> input_member
    'invited' -> input_invited
    'banned' -> input_banned

Outputs (declared order) and their functions:
    'intended' -> output_intended(inputs)
    'slip' -> output_slip(inputs)

Assumptions (the declared scope, checked by in_scope(inputs)):
    none; every complete assignment is in scope.

Input contract:
    Every required input must be exactly True or False (type(value) is bool). Missing
    inputs, None, strings, integers (including 0 and 1), and keys that are not declared
    inputs raise InputError before anything is evaluated, including inputs that a
    short-circuiting operator would never read. Results are always bool.

Scope:
    Decision functions raise OutOfScopeError when the inputs violate an assumption; an
    out-of-scope assignment is never turned into a False result. Pass check_scope=False
    to evaluate without the scope check, and use in_scope(inputs) to test it separately.

Usage:

    import tangibool_model as model

    model.evaluate({'member': False, 'invited': False, 'banned': False})
    # -> {'intended': False, 'slip': False}
    model.output_intended({'member': False, 'invited': False, 'banned': False})
    # -> False
    model.evaluate({'member': 1, 'invited': False, 'banned': False})
    # raises InputError: 1 is an int, not a bool
