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.

Per-session state replaces process-wide globals

Under the hood
Useful3 Signal3
Session State

Per-session state is now inherited by forked sessions, so a child no longer overwrites its parent's.

What

State that used to live once per process now lives on the session and is inherited by forked sessions, so a child session no longer shares or overwrites its parent's. This covers observer pairings, the autonomous-loop preamble latch, compaction precompute, the worktree resume refusal, memory sync notices, command history, known Slack channels, and path and directory scan caches.

Details
  • Forks read the parent's values through their root session rather than starting empty.
  • Post-compaction cleanup and the observer arm and retire helpers now take the session as an argument.

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