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.

Sessions

A background session left by another account is dropped rather than reattached under yours.

What

If a background session was left by one account and Claude Code starts under different credentials, the old session is dropped and a fresh one started with history upload suppressed, rather than being reattached to the wrong account.

Details
  • Applies when the stored owner account does not match the current one, and when the stored identity cannot be read at all.
  • In the mode that must reattach or fail, this raises a terminal error instead of minting a new session.
  • Outcomes are counted under rc_cross_account_suppression with reasons including torn_entry_pair and identity_unreadable.
Evidence

rc_cross_account_suppression

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