What
Pending language-server diagnostics, the ask-Claude fallback exchange history, shell hint delivery, worktree resume refusals and agent-observer pairings all moved from process globals onto the session. Nothing changes for a single session, but these are no longer shared across sessions in one process.
Details
Diagnostics are now looked up per session and the reset entry point was renamed to clear all state.
The old standalone history class was deleted; that history now hangs off the session.
Evidence
LSP Diagnostics: Resetting all state
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
