description: "Evaluates a caller-declared operator-exit and data-portability posture: per data category, whether an export path exists and whether its format is open or proprietary, producing a stranded-category list rather than a coverage ratio. Checks declared operator- versus supplier-control of named components and flags a contractual-operator claim unsupported by that declared control, single-supplier dependencies with no declared substitute, escrow arrangements, and notice period / transition-assistance terms. Undeclared is a distinct, non-failing state from an explicit negative declaration throughout. Evaluates declarations only -- never a supplier audit, vendor rating, or enforceability opinion, and no output names or characterises a supplier. Region-portable: every fact is a caller-declared input, with no country, currency, scheme or supplier hardcoded. Deterministic arithmetic only. Zero network, zero PII."
