Improve OpenChamber responsiveness under large session workloads while fixing cache, synchronization, and persistence correctness across runtimes, projects, directories, and worktrees. - prioritize selected and visible sessions during bootstrap and defer non-critical enrichment work - reduce redundant message loading, event processing, store publication, and hidden sidebar work - prevent stale session and message requests from overwriting newer authoritative state - preserve existing data when authoritative fetches fail instead of treating failures as successful empty responses - scope session materialization, messages, drafts, queues, todos, pins, permissions, folders, tabs, Git state, and pull request data by runtime and directory identity - harden runtime switching, reconnect, cleanup, mutation reconciliation, and persisted-state ordering - preserve live subagent Task linkage when metadata arrives after an older message request or while streaming parts are suspended - coalesce overlapping tail refreshes without losing newer refresh demand - improve cold-session loading by moving deferrable work out of the critical bootstrap path - isolate URL authentication, mobile credentials, native secrets, and other runtime-owned state across endpoint changes - bound long-lived caches and remove avoidable allocations from event and rendering hot paths - limit virtualization to archive collections where it improves rendering without disrupting active sidebar layout - stabilize session folders, pin ordering, expanded state, and persisted sidebar behavior - open skill files through the same secure editor and outside-workspace grant flow used by file navigation, including worktree sessions - expand regression coverage for stale completions, runtime collisions, reconnect behavior, persistence races, authoritative empty results, and subagent refresh ordering - document the updated synchronization, cache ownership, performance, and runtime-isolation invariants
