Optional reasons now follow fact versions through review and API readback, with private chat threads omitted.
A reason is not verified truth
NOAN’s November 3 update lets agents attach an optional source‑backed reason when creating or updating a fact. A request to change the record is not that reason: reviewers need evidence supporting the claim. NOAN says a person still verifies it. November 3 entry
Readback has explicit gaps
The reason appears on approval cards, version history and decision details; absent reasons stay hidden. MCP fact listings and REST version reads return the rationale or null. The assistant’s chat thread is recorded as a private source and excluded from API returns, rather than disclosed alongside the rationale. NOAN changelog
A broader design question
For the broader architecture decision, the trusted‑memory and authority reference frames memory trust and audit boundaries as design questions. It is a learning resource rather than product‑control validation.
