- The similar-question cache embeds a question as its project would: a
project kept in the cluster has external fallbacks refused, and an
embedding model outside the cluster is not asked at all. The vectors are
compared outside the cache's lock. The question's bound is in characters.
- The restorer puts values back in streamed tool calls' arguments (escaped
for the JSON they are), completions' text and reasoning, each held across
events on its own, and releases a held tail with the finish event. A
whole answer is walked as JSON, so a value with a quote no longer breaks
tool-call arguments.
- An outside guardrail service reads the user's turn as redacted, and a
streamed answer once rather than at the finish chunk and again at the
end. guardrails.md says it can stop a stream only under buffer_all.
- A replica's smoothed time to first token is forgotten after five minutes
without an answer: one found slow and then given nothing was never tried
again.
