ADR A-10: Behaviour activation policy

Status

Accepted

Context

A selected transition still needs a declared rule for when it becomes effective. Immediate, deferred, and manually released transitions are semantically different and must not be inferred from operational timing.

Decision

Every transition definition declares one bhv:activationPolicy. Baseline policies are:

• bhv:ImmediateActivation
• bhv:DeferredActivation
• bhv:ManualActivation

A deferred transition may additionally declare one scheduling or reset recurrence through Quantification, but the policy itself remains a Behaviour concern.

Consequences

• Execution timing is part of the semantic model.
• Deferred and manual flows are representable without inventing engine-specific state.
• Quantified schedules integrate through projection rather than by duplicating time logic in Behaviour.
