Global Memory is inherited by EVERY agent in this workspace at launch, so this changes what every agent — not just you — is instructed with at their next launch (use MemoryRevert to restore your own native memory instead). This does NOT delete history — it records a new version (source: \"revert\") whose content matches the target, same as `git revert`. Use it to undo a bad or fabricated Global Memory write once you've confirmed via GlobalMemoryHistory/GlobalMemoryDiff which version to restore. Cannot revert AgentMux's own system-tier entries.",
