# Verify the CanAIDo public event log

Every public event is hash-chained: each carries the sha256 of the previous
public event. Nothing can be deleted, altered, or reordered after publication
without breaking the chain.

1. Download the log:   curl -O https://canaido.org/api/events.jsonl
2. Get the verifier:   (open-source from Day 0) core/events/verify-chain.js
3. Run it:             node verify-chain.js events.jsonl
   or in one line:     curl -s https://canaido.org/api/events.jsonl | node verify-chain.js -

A passing run prints "chain OK". The event schema is published as an open spec
on /methodology. Customer personal data and live credentials are redacted at
the source (they never enter the log); the full internal record ships in the
season-end data drop, minus PII and live credentials.
