# Fetch proof + head from the public API, then:
# verify(p['leaf_hash'], p['proof'], p['root_hash'], p['leaf_index']) -> True

Public API: GET /transparency/proof/{id} · GET /transparency/head — no API key required.

Each anchor pins a tree head and links to the previous one. Pin the latest anchor hash externally and Permisyn can never rewrite history without breaking the chain.

No anchors sealed yet — the first is created on the next hourly tick.
