	Changing the global filter used to call stopTrace + beginTraceCmd, which detached and re-attached every tracepoint and re-loaded the BPF object. On heavily loaded I/O systems that took several seconds and showed an 'Attaching tracepoints...' overlay each time. The probe set never depends on the global filter (ShouldIAttachTracepoint only reads CLI regex flags), so the restart was gratuitous. Now the eventloop holds its filter behind atomic.Pointer with SetFilter / Filter accessors, and the trace starter registers el.SetFilter via the runtime bindings as a SetLiveFilterSetter callback. applyGlobalFilter and undoGlobalFilter call runtime.applyLiveFilter first; only if no trace is running do they fall back to the full restart path.
2026-03-18	refactor: extract pairTracker and extend fdTracker to reduce eventLoop ↵	Paul Buetow
	responsibilities (task 428) The eventLoop struct held 20+ fields across 5+ responsibilities (SRP violation). Extract two cohesive sub-structs: - pairTracker: enter/exit pair matching, age-based LRU pruning, and DurationToPrev tracking. Replaces enterEvs/enterEvAges/prevPairTimes/ maxPendingEnterEvs/cacheAge fields with a single embedded value. - fdTracker (extended): absorbs procFdCache/procFdAges/maxProcFdCacheSize, moving all procfs-resolution cache logic (resolve, cache, prune, delete) off eventLoop and onto the tracker that already owns the fd table. eventLoop drops from 20 fields to 12. All methods that previously reached into eventLoop fields now live on the struct that owns the data. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
