2026-05-13	refactor: make receiver types consistent per type (pointer receivers)	Paul Buetow
	fileRankHeap Len/Less/Swap converted to pointer receivers to match Push/Pop; bubbleChart HasNodes and AnimationState Settled converted to pointer receivers to match all other methods on their types. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13	use errgroup instead of WaitGroup for concurrent snapshot builders	Paul Buetow
	Replace sync.WaitGroup with errgroup.Group in buildSubSnapshots so errors from sub-builders (buildSyscallSnapshots, buildFileSnapshots, buildProcessSnapshots, buildHistogramSnapshot) are captured and propagated rather than silently dropped. Change Engine.Snapshot() to return (*Snapshot, error), update runtime.SnapshotSource and dashboard.SnapshotSource interfaces accordingly, and adjust all callers in tui.go, dashboard/model.go, and the test helpers. Each sub-builder now returns (result, error); the error return is currently always nil but establishes the contract for future validation. The per-type Snapshot() convenience methods (histogram, syscall, file, process) panic on error since they are internal helpers where failure would be a programming bug.

2026-05-08	add duration metric, tolerate missing tracepoints, ship el8 build	Paul Buetow
	- Bubbles, treemap, icicle, and the live flamegraph 'b' cycle now include syscall duration (sum) as a third metric alongside events and bytes. Statsengine snapshots expose TotalLatencyNs to support this. - AttachAll takes an optional warn callback. Production passes one so older kernels that lack newer tracepoints log a warning and keep going instead of aborting startup. - Dockerfile.el8 + scripts/build-with-docker-el8.sh + mage buildDockerEl8 produce ior.el8, a static binary built against Rocky Linux 8 glibc for RHEL/Rocky/Alma 8 hosts. - README.md documents installing mage and the new el8 target.
