`IMPERSONATION_READ_ONLY`

HTTP 403

Something about the request must change

A mutation was attempted on a served request under a read-only impersonation grant; the request is refused before any handler runs so it has zero effect. The session's write mode is fixed at begin time and never inferred from the request.

How to fix it (contract guidance)

Re-open the impersonation session with allowWrites:true to make the documented mutation, or perform only reads under the current session.

Observed recovery

Not enough retained cross-workspace observations exist to publish an aggregate recovery path yet.

Publication requires at least 3 distinct workspaces. This is withheld data, not evidence that no recovery happened.
