plog verify walks an agent’s hash chain and checks that every event’s hash is correct and all links are contiguous.

plog verify --agent-id my-agent
plog verify --agent-id my-agent --server http://localhost:7600

​
Flags

​
What it checks

  1. Hash correctness — recomputes each event’s hash and compares
  2. Chain continuity — verifies each event’s prev_hash matches the previous event’s hash
  3. Sequence integrity — checks for gaps in the sequence
