Summary
session prepare-clientserve()into startup diagnostics, while keepingafs doctor's independent registry buildafs.context_packfrom the mypy grandfather baseline after cleaning its remaining type errorsWhy
Each wrapper startup could perform two broad bootstraps, two skill discovery/ranking passes, and (on a stale cache entry) two recursive mount fingerprint walks. Every stdio MCP process also rebuilt its full tool registry in background diagnostics. Expired five-minute cache entries were never pruned, so the rebuildable cache could grow indefinitely.
The changes keep output contracts intact and only reuse state after validating the context and scope. Cache pruning is best-effort, only considers 64-character lowercase-hex JSON names owned by this cache, skips symlinks, retains the just-written entry, and never touches unrelated JSON files.
