- Tools: cancel a session’s subagents when it closes
- Pager: keep the whole plan in scrollback and separate reasoning from output in minimal mode
- Pager: probe terminal version over DA2 and include it with feedback
- SuperGrok Plus: identity, CLI, and analytics tier surfaces
- Shell: inherit the session process scope into subagents

- Tools: reap a session’s LSP servers when it closes
- Tools: fix contradictions and defects in tool descriptions, schemas, and harness pools
- MCP: reap stdio MCP children on session close
- Shell: reuse spawn-time skill discovery for session telemetry

- Shell: self-heal corrupt session-search SQLite cache
- Workspace: cap workspace-server tokio workers on many-core hosts
- Shell: reap a session’s child processes when it closes
- Crash handler: capture SIGABRT so panic-aborts leave crash reports
