Referential integrity

Mapped mission fields are validated against these canonical IDs. A mission fails validation when it claims a countable specialist precondition without a matching infrastructure record.

Infrastructure is not a dispatched resource

A generation precondition does not automatically prove:

• that a vehicle from the building must attend;
• the building’s vehicle capacity;
• staffing or classroom capacity;
• purchase price or construction duration; or
• whether an extension is active by default.

Examples:

• Mass Casualty Extension is separate from Mass Casualty Equipment.
• Recovery Centre is separate from the number of assets to tow.
• Airfield Operations Extension is separate from Airfield Operations Vehicles.
• Active Drone counts are generation state, not automatically a Drone dispatch row.

Complete evidence disposition

Release v1.4.2 resolves all 80 tracked fields—cost, build time, capacity and compatible parent building for every record—without inventing values:

• 9 verified fields carry a directly published value;
• 65 not-published fields record that the checked official source set does not publish a value; and
• 6 not-applicable parent fields belong to standalone buildings.

Published detail currently includes the HART Base and Police Helicopter Station costs and maximum expansion levels, plus the Police & Public Safety Extension cost and dedicated Detention Van space. Three extension records also have verified parent-building relationships. A not-published field never means zero, free, instant, unlimited or unavailable.

The schema and semantic validator require all four evidence decisions on every record. A missing decision, a verified field without a value or an unpublished field carrying a value fails validation.
