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.

Perfetto Tracing Removed

The Perfetto performance tracing feature has been removed from this release.

Evidence

Removed PERFETTO_TRACING flag check, removed trace writing functions writePerfettoTrace, writePerfettoTraceSync, removed all [Perfetto] logging statements

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