What
Dozens of scattered module-level variables, maps and sets were moved into lazily created state objects reached through accessors, covering plugin state, agent and task state, git scrub paths, config caching, teammate mailboxes and terminal capability probes. Several holders gained a reset() method, and a process-wide promise-chain lock became a factory producing per-instance locks, so in-process state can now be torn down and rebuilt.
Details
MCP errors are now dispatched into a store as { type: "mcpError", serverName, error } rather than accumulated in a module array.
New named fields include agentTranscriptSubdirs, bareGitRepoScrubPaths, installedPluginsFile, terminalRejects, childProcessTmpDirMemo and scriptCapsLatched.
No user-visible behaviour change.
