DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Once-per-process telemetry latches share one registry; event names are unchanged.
What's wrong with this entry?
Anonymous. No account, no email.
What
Module-level booleans that kept certain events to once per process were replaced by a shared registry. Event names, including the first-scan and MCP role fallback events, are unchanged.
Evidence
coordinator_mcp_no_comms_role_fallback
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
