  "message": "refactor(bigtable): address igor nits on Session debug surface\n\nSix nits from the igor-reviewer-agent review of PR #20211:\n\n- Introduce typed const SessionEventKind (close/hb-missed/hb-alive/\n  ctx-done/retry) so writers landing in the follow-up vRPC and lifecycle\n  PRs can\u0027t drift on the string literal.\n- Replace the O(N) copy-shift in recordEvent with a wrap-index scheme\n  matching latencySamples\u0027 existing pattern (eventsNext cursor).\n- peerInfoSummary: %x → %d for AfeID and gfe — the rest of the pkg\n  renders these as decimal.\n- setChannelIndex: unexport (writer is package-internal) and take\n  int32 directly instead of silently narrowing from int.\n- sessionDebug.init: take *sessionTracer instead of SessionType so the\n  redundancy with Session.sessionType goes away. NewSession threads\n  newSessionTracer(sessionType) through at the call site.\n- Add a doc comment on the sessionDebug struct pointing at the follow-up\n  PRs where the counter / close-reason / remote-addr writers land.\n",
