Retain detached Markdown DOM for eight recent sessions so medium-frequency session switching can restore more first-screen content without reparsing it.
Limit each session to four cached parts, reducing the worst-case retained fragment count from 36 to 32 while preventing long sessions from dominating the cache.
Keep sidebar rows independent from the active sync directory by moving export history loading behind an explicit-directory command.
Make active-project selection preserve project topology and remove activeProjectId from mounted group render props. Reuse a per-session-array ID index so subscription snapshots do not repeatedly scan session lists.
Batch global session, status, ordering, and activity timing mutations at the existing directory event boundary so large subagent bursts publish each owner once.
Maintain active session roots, children, and directory buckets in the global store, reuse them in Sidebar projections, and avoid rebuilding live aggregates and structural data for unrelated renders while preserving authoritative ordering reconciliation.
Skip mutation history when no settings operation is in flight and merge updates that share the same operation visibility window. This keeps stale-response reconciliation unchanged while preventing history from growing with repeated debounced updates.
Add a repeated-update regression covering an older pending load and latest-value reconciliation.

Keep settings mutation revisions and in-flight operations behind a private tracker so stale GET and PUT responses cannot overwrite newer local settings.
Remove redundant runtime identity and numeric operation IDs. Use operation object identity while preserving runtime reset and mutation retention behavior.
