Function apply_common_actions

atomic-agent/src/turn/phase.rs:632–659

Apply the common (non-strategy-specific) actions from a transition result to the given session state. This updates `phase`, `last_interaction`, and `ended_at` as indicated by the transition actions. Returns the subset of actions that require strategy-specific handling (e.g., `RecordTurn`, `RecordIfChanged`, `WarnStaleSession`). The caller is responsible for dispatching those. # Example ```rust

(
    state: &mut S,
    result: &TransitionResult,
)

/// // session.last_interaction was updated
/// ```
pub fn apply_common_actions<S: SessionState>(
    state: &mut S,
    result: &TransitionResult,
) -> Vec<Action> {
    state.set_phase(result.new_phase);

    let mut remaining = Vec::new();

    for action in &result.actions {
        match action {
            Action::UpdateInteraction => {
                state.touch_interaction();
            }
            Action::ClearEndedAt => {
                state.clear_ended_at();
            }
            // Strategy-specific actions are passed through
            Action::RecordTurn
            | Action::RecordIfChanged
            | Action::DiscardIfNoFiles
            | Action::WarnStaleSession => {
                remaining.push(*action);
            }
        }
    }

    remaining
}
