State Tracking

This page covers state tracking implementation details.

Storage

State stored in tasks.last_known_state JSON column:

CREATE TABLE tasks (
  ...
  last_known_state JSONB,
  ...
);

Comparison Algorithm

def compare_states(current, previous):
    if not previous:
        return True  # First execution

    # Check condition status change
    if current["condition_met"] != previous["condition_met"]:
        return True

    # Calculate text similarity
    similarity = calculate_similarity(
        current["answer"],
        previous["answer"]
    )

    return similarity < 0.85  # 85% threshold
