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.

Claude Code v2.1.227

Session history is withheld when the signed-in account changed

Sessions

Resuming a session under a different account starts fresh instead of replaying the old history.

What

When Claude reattaches to a session that was started earlier or handed over from another process, it now compares the account and organization recorded on that session against whoever is signed in now. On a mismatch it starts a fresh session instead and withholds the earlier history rather than replaying it under the new account.

Details
  • The handoff carries the previous owner identity in new environment variables including CLAUDE_BRIDGE_REATTACH_OWNER_ACCT.
  • A suppression record is written into the transcript and rc_cross_account_suppression is emitted, with torn_entry_pair and scan_budget_exhausted variants for partially written or too-large transcripts.
Evidence

CLAUDE_BRIDGE_REATTACH_OWNER_ACCT

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