What

Sync between machines now reports a barrier event plus events for frame disagreement, mid-turn sync, and publishing or taking in files between tool calls. The barrier event records whether both sides agree on file state ("up", "down" or "both"), why they do not (peer too old, peer stale, no frame of our own, peer does not take files), plus timing and event counts. Reason strings pass through an allow-list that maps anything unrecognised to "other".

Details
  • No gate; emitted inside a try/catch on the sync path.

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