"""
test_220_closure_registry_sweep.py — Load and execute every registered closure.

The closure registry (closures/registry.yaml) lists ~80 closure modules
across 15 domains. Previously, no test verified that every registered
closure can be imported and executed with valid inputs. This module
performs a comprehensive sweep.

Derivation chain:  Axiom-0 → Tier-0 protocol → closure validation
    A registered closure that fails to load or produce well-formed
    output is a broken seam — it cannot participate in the collapse-
    return cycle.

Sections
--------
§1  Registry structure:   YAML loads, all paths exist
§2  Astronomy closures:   7 closures, output validation
§3  Everyday physics:     4 closures + batch, Tier-1 on outputs
§4  Finance embedding:    1 closure, embedding validation
§5  Security closures:    Kernel/diagnostic closures
§6  Quantum mechanics:    6 closures, regime + output validation
§7  Nuclear physics:      7 closures, NamedTuple outputs
§8  Cross-domain sweep:   Every domain produces valid output
