Forking a session from the resume picker now carries history suppression forward

Sessions

Forking a session from the resume picker now carries over suppression and parent records properly.

What

Forking a past session from the resume picker previously only replayed content replacements. It now runs the shared fork helper, which strips the source session's worktree session and relocated working directory, records the fork's parent, and copies history suppression onto the new session id when the source was suppressed or known to be tainted.

Details
  • The suppression record on the destination session is written with cause fork_inherit.
  • The fork helper is called with stripWorktreeSession and stripRelocatedCwd set, plus the destination session id.
  • Neither the suppression record type nor the fork options existed in v2.1.226, so forks made from this path previously started without inherited suppression.

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