Changes
Add write-ahead log (WAL) to record state changes during direct deployment, enabling recovery of partial state if deployment is interrupted.
Why
Today, if deployment is interrupted before
Finalize(), no state is saved, and created resources become orphaned. The WAL writes each state change immediately to disk and replays them on restart.Tests
Unit tests added for WAL save/replay, delete/replay, finalize cleanup, and edge cases.
