Pattern H ("Stale plugin-cache versions") recommended deleting stale
version dirs under ~/.claude/plugins/cache with no warning that a
currently-running session may still hold one of those versions for its
whole lifetime. "Stale" is judged against installed_plugins.json (what
NEW sessions load), so the recommendation could reproduce the exact
footgun that broke a live session during C4: deleting the dir pulls the
files out from under the running session, which then breaks and must
/exit + restart.
Extend the recommendation text with the live-session caveat. No new
finding ID/scanner, no token counts changed (recommendation string only)
-> --json/--raw stay byte-stable, frozen v5.0.0 + SC-5 + default-output
snapshots untouched. +1 test (1297).
