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.

Two new telemetry events

Under the hood
Useful1 Signal2
Telemetry

Two new counters cover swept placeholder bridge sessions and iTerm2 crash-restore probes.

What

Two events were added that did not exist before: one recorded when a placeholder bridge session turns out to have been used and is swept away, and one from the iTerm2 crash-restore probe, carrying whether a backup path was found.

Details
  • tengu_bridge_placeholder_used_session is emitted with v2: !0 immediately before removal.
  • tengu_dead_probe_iterm2_crash_restore reports the backup-path result.
Evidence

tengu_dead_probe_iterm2_crash_restore

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