2026-03-18refactor: 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>
2026-03-18refactor: replace reflect.TypeOf dispatch in exit handlers with type switch ↵Paul Buetow
(task 432) The exitHandlers map keyed by reflect.Type was a reflection-based dispatch table that incurred allocation and reflection overhead on every event pair in the hot processing path. Replace it with a plain type switch in handleTracepointExit, which the compiler resolves statically. Removes: initExitHandlers, typeKey, mustBeType, newTypedExitHandler, exitHandlerRegistry, the exitHandlers struct field, and the tracepointExitHandler type alias — all dead after the switch. Fixes a pre-existing uint→uint64 mismatch in stats(). Updates tests to target the new default branch directly. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

2026-02-21fix: close_range path resolution - lookup fd before deleting from mapPaul Buetow
Move e.files[fd] lookup before the close_range fd cleanup loop in the FdEvent handler so the file path is resolved while the fd still exists in the map. Previously, close_range events always fell through to file.NewFdWithPid() which couldn't resolve the path since the fd was already closed. Also add unit test assertion verifying ep.File resolves to the correct filename for close_range events.
