Source Intelligence

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.

Container-side file sync engine gone

File Sync

The old container file-sync engine and all its sync warning messages are gone from your transcripts.

What

The older sync engine that ran inside cloud containers and mirrored a directory to the checkout on your machine has been removed, along with every notice it inserted before your messages: the explanation that the directory is synced, the auth-failing, auth-restored and halted warnings, and the "files not copied into this session" notices. You will not see those messages again on this build.

Details
  • Its per-turn pull and push loop and its trash and conflict bookkeeping under .ccr-dir-sync are gone.
  • Its telemetry events for pull, push, base, rehome and the first-turn hold no longer occur anywhere in the build.
  • Only a leftover record-path helper still mentions the directory name.
Evidence

File sync with the user's machine has stopped for the rest of this session

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