The repository now includes stronger regression tests around checkpoint/DAG behavior, RPC handling, state changes, gas models, object management, and validator backup.

Covered locally

Transaction-driven checkpoint behavior.
DAG vertex deduplication and retained-store lookup.
Snapshot state-root validation paths.
Encrypted validator backup round trips.
RPC method parsing and transaction builder validation.
Native transfer object/gas separation.
Move runtime object/state/gas/supply behaviors.
Access-set and scheduler conflict primitives.

Long-running tests to run before production

4-node root-consistency soak with restarts.
High-throughput transfer load with many independent sender/object sets.
Conflict-heavy transfer load with same-object retries.
Byzantine peer simulation: malformed DAG vertices, duplicate payloads, stale checkpoints, and inconsistent roots.
RPC DoS simulation: heavy views/builders, large bodies, bursty per-client traffic.
Fuzzing around transaction parsing, object IDs, dynamic fields, snapshot import, and P2P chunk handling.

Suggested soak command

Use the repository soak script as the starting point:

.\scripts\run-adversarial-soak.ps1

Run it in a clean devnet first, then gradually increase duration, node count, and transaction pressure.
