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.

Claude Code v2.1.222

Bridge recovery has a rebuild budget and richer failure telemetry

You'll notice
Useful2 Signal0
Remote Bridge

A remote bridge that cannot recover now stops retrying after a budget and tells you why.

What

Recovery from 401, 4091 and 4093 transport closes is now table-driven, and repeated transport rebuilds are capped so a bridge that cannot heal stops retrying and says why.

Details
  • each close code maps to its own reconnect detail, cause, diagnostic, terminal-vs-retry fetch failure classification and recovered code
  • 4093 rebuilds within a one hour window are budgeted; exceeding the budget stops recovery with an explicit message
  • new presence telemetry codes: recovery_exhausted, heartbeat_budget_exhausted, recovery_no_oauth_token, recovery_reauth_required, recovery_credentials_fetch_failed, recovery_credentials_rejected, recovery_abandoned_at_teardown, bridge_connect_died_before_presence
Evidence

presence heartbeats to the server kept failing after repeated reconnects

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
