Fully Canonical Mission Batch 12

Batch 12 promotes Tree on the road, the exact mission unlocked by mapping the official three-way appliance group.

Verified dispatch model

ID	Mission	Fire Stations	Guaranteed	Additional alternative	Expansion	Average credits
12	Tree on the road	1	1 Fire Engine	1 Fire Engine, Rescue Support Vehicle or Aerial Appliance Truck	Road accident	310

The retained source represents the guaranteed Fire Engine and the three-way choice as additive requirements. The alternative therefore does not replace the guaranteed appliance.

Evidence safeguards

• Exact official ID, UK name, prerequisite, reward and resource quantities are retained.
• The three-resource choice is represented through requirements.alternatives.
• The published expansion into Road accident is retained and resolves to official mission ID 25.
• No patients, personnel, probabilities, variants, overlays or unsupported additional fields are present.
• Strict key equivalence enforces both the guaranteed and alternative requirements.
