"""Merge-friendly ACK task records.
``tasks.yaml`` remains the small project manifest. When it contains a
``taskStore`` mapping, task state is materialized from immutable record files
under the configured directory. Legacy boards without that mapping keep
their original single-file behavior.
Records are complete task snapshots rather than patches. A later record
names its parent record(s), so a concurrent edit produces multiple heads and
is reported as a semantic merge conflict instead of being silently resolved
by file order or timestamps.
