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.

Folder sync reports per-pass statistics

Under the hood
Useful1 Signal2
Cloud Sync

Folder sync sends per-pass stats so stalled syncs can be diagnosed server-side.

What

The folder sync engine now emits telemetry for each pass it makes, so slow or stalled syncs can be diagnosed from the server side rather than only from the local log.

Details
  • tengu_dir_sync_folder_repo carries a pass dimension of tree, push or receive, plus counts and timings such as listed_paths, hashed_files, hash_ms, plan_ms, held_back, blobs_stored, bytes_planned, pack_bytes, objects_read and decode_ms.
  • tengu_dir_sync_folder_seed covers the initial pass, and tengu_dir_sync_folder_store_lost fires when the local sync store cannot be read or written at session start.
  • Emitted only on the folder sync path; none of these names existed in 2.1.245.
Evidence

tengu_dir_sync_folder_repo

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