Function: hashSessionKey()

hashSessionKey(key): string

Defined in: src/core/toolSessions.ts:217

A short, stable digest of an isolation key.

The key carries tenant, principal and the hosting sessionId. Publishing it on the event wire would put a user identifier into every exporter's payload — so the wire carries this instead, which is enough to JOIN two rows and not enough to name whose they are. meta.sessionId already carries the session legitimately (9.4.0); the payload does not repeat it.

SHA-256, first 12 hex chars, wherever node:crypto resolves. In a browser bundle, where it does not, this falls back to the package's non-cryptographic FNV-1a digest — stated here rather than implied, because a fallback nobody documented is how "hashed" comes to mean less than a reader assumed.
