What
A batch of module-wide singletons now live in a per-host keyed holder, which matters when more than one Claude Code host runs inside a single process.
Details
Moved: terminal capability state, the tmux option probe, startup profiler state including its memory snapshots, MCP and session wiring, bypass-permissions rearm, team store presence, agent file entry cache, bridge subscription, pending model usage, and agent-observed notes.
IDE detection also moved and gained jetbrainsPluginInstalled, a cache of whether the claude-code-jetbrains-plugin is installed, cleared alongside the rest of the IDE state.
Evidence
hasTeamStore, jetbrainsPluginInstalled
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
