-# action_scheduler.py testsdd
-# Smart Action Scheduler for Bjorn - queue-only implementation
-# Handles trigger evaluation, requirements checking, and queue management.
-#
-# Invariants we enforce:
-#   - At most ONE "active" row per (action_name, mac_address, COALESCE(port,0))
-#     where active ∈ {'scheduled','pending','running'}.
-#   - Retries for failed entries are coordinated by cleanup_queue() (with backoff)
-#     and never compete with trigger-based enqueues.
-#
-# Runtime knobs (from shared.py):
-#   shared_data.retry_success_actions : bool (default False)
-#   shared_data.retry_failed_actions  : bool (default True)
-#
-# These take precedence over cooldown / rate-limit for NON-interval triggers.
