+[Parmana](https://github.com/pavancharak/parmana-core) decides whether an agent's action may run under a versioned policy,
 requires a signed human approval where the policy says so, and signs a record of every decision, refusals included.
 
 This integration treats those records as TRACE external evidence. Parmana issues no TRACE Trust Record. An agent
-runtime that does points at the Parmana record for its step through `references` (trace-spec §3.1.2):

+Parmana's canonical form is JSON with recursively sorted keys. For plain JSON values it matches RFC 8785, and `parmana-core` pins this with conformance tests. Two non-JSON inputs differ: `undefined` values are dropped and `Date` values become ISO strings. TRACE does not re-sign its records: `parmana_evidence.py` checks those signatures offline, with Parmana's public key and nothing else.
