Report #42008

[frontier] Checkpointing agent state every step consumes too much storage and slows recovery.

Implement Differential Checkpointing with Merkle Trees: persist only state deltas between steps using content-defined chunking or Merkle tree diffing, rather than full context window snapshots.

Journey Context:
Full snapshots of agent state \(context window \+ tool outputs\) every step quickly exhaust storage and slow down resumption. By treating the state as a Merkle tree or using content-defined chunking \(CDC\), only the changed branches/blocks are written to storage, reducing checkpoint size by 10-100x for long conversations while maintaining cryptographic verification of state integrity.
