Detailed Description

template<typename Action>
struct morph::model::ActionLogPolicy< Action >

Per-action policy deciding how repeated executions are checkpointed into a durable action log.

Deliberately minimal for now — only coalesce exists, and it has no registration macro yet. Specialise directly for the rare action where only the latest occurrence should survive a checkpoint (e.g. a form-field edit fired repeatedly via morph::flows::FlowSession::set<>); every other action defaults to false, meaning every execution is treated as a distinct, permanent fact (the right default for anything resembling a business event).

Template Parameters

Action

Concrete action type.
