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.

Sync objects addressed by full path, transport simplified to one client

Under the hood
Useful2 Signal3
Directory Sync

Synced objects now use full paths and always publish through one client.

What

Synced objects are now identified by a full directory-plus-suffix path rather than a bare name, and outbound publishing always goes through the direct client with a worker-side marker and optional stall and restart-pause timings. The older fallbacks (size-threshold direct upload, an over-cap row write, and an etag memo on rejected requests) are gone from this path.

Evidence

a sync object is named by a lowercase-hex sha256

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