2026-05-17docs: add comprehensive syscall tracing expansion planPaul Buetow
Plan-only document covering the ~230 Linux syscalls ior does not yet trace. For each not-yet-covered syscall the plan records whether it takes/returns a file descriptor, whether it has a meaningful bytes or size dimension that could feed the existing read/write/transfer accumulators, the suggested TracepointKind (existing or new), extra per-event metrics, and a priority tier. Also enumerates the taxonomy extensions required (new TracepointKind values, retClassification additions, family/dimension tags), risk areas (high-cardinality syscalls like futex/clock_gettime), and a phased rollout from "free wins" (network bytes already mapped but blocked by shouldIgnore) through process lifecycle to the long tail. No code changes.
2026-05-14use configurable fastRefreshEvery for InitCmd on flame and stream tabsPaul Buetow
Change tabDescriptor.InitCmd from func() tea.Cmd to func(*Model) tea.Cmd so the initial tick for the flame and stream tabs uses the model's fastRefreshEvery interval rather than hardcoded 200 ms constants. Both call sites in Init() and postKeyTransitionCmd() now pass the model pointer. The now-unused streamTickCmdFn/flameTickCmdFn package-level adapters are removed; the TabFlame and TabStream registry entries use inline closures that delegate to m.flameTickCmd()/m.streamTickCmd().

2026-05-14docs: document -tui-fast-refresh flag in AGENTS.md TUI Behavior sectionPaul Buetow
Add a bullet explaining the default (250ms), what it controls (flamegraph and stream tab refresh cadence), and that setting it to 0 disables high-frequency refresh. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-14wire TUIFastRefreshInterval into dashboard model and update testsPaul Buetow
Add fastRefreshMs parameter to NewModelWithConfig so callers can supply the high-frequency tick cadence for stream and flame tabs. Convert the streamTickCmd/flameTickCmd package-level functions to model methods that honour fastRefreshEvery (falling back to the 200 ms constants when zero for backward-compatibility). Add SetFastRefreshInterval setter so RunWithTraceStarterConfig can apply cfg.TUIFastRefreshInterval after construction. Update all 68 test call sites to pass fastRefreshMs=200 and add three new tests covering zero-fallback, stored value, and setter behaviour. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13add TUIFastRefreshInterval flag to flags.ConfigPaul Buetow
Add TUIFastRefreshInterval time.Duration to flags.Config struct with a default of 250ms and register it as the -tui-fast-refresh CLI flag so callers can tune or disable the high-frequency TUI refresh cadence for the flamegraph and stream tabs.

2026-05-13refactor: break down functions exceeding 50 lines into smaller helpersPaul Buetow
Split 22 production files across the codebase — event loop, TUI models, probe manager, dashboard, export, flag parsing, code generation, and ioworkload scenarios — so that no function body exceeds 50 lines. Each extracted helper carries its own comment explaining its role. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13keep View() pure by moving state transitions into Update() handlersPaul Buetow
The dashboard model's View() was mutating sub-model state on every render: it called streamModel.SetFooterVisible() and flameModel.SetViewport() on local copies instead of keeping those fields in sync through Update(). Moved the sync points to the Update() handlers that trigger each change: - handleWindowSize: syncs stream footer visibility alongside SetViewport - handleHelpToggleKey: already updated flame viewport; now also updates stream footer visibility when the help bar is toggled - handleKey: syncs flame viewport when switching to the flame tab, covering the case that window-resize and help-toggle do not Aligned the stream model's initial showFooter value with the dashboard's default showHelp=false in NewModelWithConfig so there is no mismatch on the first render. Also extracted numeric tab shortcuts into the tab registry via ShortcutKey fields so handleShortcutKey no longer needs updating when tabs are added. Updated two tests that bypassed Update() to set dimensions directly; they now use WindowSizeMsg so sub-model viewports are initialised correctly under the new pure-View contract.

2026-05-13refactor: extract outputFormatter collaborator from eventLoopPaul Buetow
The printCb and warningCb function fields on eventLoop bundled two distinct concerns (pair emission and warning delivery) directly on the event-processing struct. This commit extracts them into a dedicated outputFormatter type that owns these callbacks plus emit() and notifyWarning() helper methods. outputFormatter is embedded (not pointed-to) in eventLoop so that existing call sites — including tests that write el.printCb = ... and el.warningCb = ... directly — require no changes beyond the three struct-literal sites in eventloop_filter_test.go that used field initialiser syntax. fdTracker and commResolver were already proper collaborator types; only the output concern needed extraction.

2026-05-13introduce Accumulator interface in statsengine to separate ingestion from ↵Paul Buetow
snapshot-building Define statsengine.Accumulator (Ingest + Reset) to represent the event-accumulation responsibility separately from runtime.SnapshotSource (Snapshot), which handles the read side. This reduces the SRP violation in Engine: callers that only push events now hold an Accumulator; callers that only read statistics hold a SnapshotSource. - Add Accumulator interface and compile-time assertion in statsengine/engine.go - Add EventIngester type alias (= statsengine.Accumulator) in runtime/runtime.go with a compile-time assertion, so callers in the runtime layer can reference the ingestion contract without importing statsengine directly - Split tuiRuntime.engine field into accumulator + snapSource so the event-loop callback holds Accumulator and wireRuntimeBindings passes SnapshotSource to SetDashboardSnapshotSource — making each consumer's dependency explicit - Simplify resetDashboardSnapshotSource in tui.go to cast for interface{ Reset() } independently of Snapshot(), removing the combined ad-hoc interface check Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13fix: stop BPF ring-buffer polling goroutine on trace end to prevent leakPaul Buetow
setupEventChannel now returns the *bpf.RingBuffer handle alongside the event channel. Both callers (runTraceWithContext, runHeadlessParquet) defer rb.Stop() so the libbpfgo polling goroutine and C ring_buffer struct are released promptly when the trace context is cancelled, rather than waiting for bpfModule.Close() to eventually call rb.Close(). rb.Stop() and rb.Close() are both idempotent, so the double-call from the defer and from bpfModule.Close() is safe.

2026-05-13refactor: move TraceFilter and tracepoint selector logic out of flags.ConfigPaul Buetow
- Add tracepoints.Selector type with ShouldAttach method and ParseSelector constructor, replacing the raw TracepointsToAttach/TracepointsToExclude regex slices on flags.Config. - Add flags.BuildTraceFilter as a standalone function replacing the Config.TraceFilter() method, keeping filter-building logic out of the config struct. - Remove stale ShouldIAttachTracepoint noise-filter entry from Magefile. - Add selector_test.go with full coverage of ParseSelector and ShouldAttach.

2026-05-13docs(agents): document testRace mage target in AGENTS.mdPaul Buetow
The testRace and goBuildRace targets already existed in Magefile.go (added in commit 70acff7) but were missing from the build/test command reference in AGENTS.md. Add the testRace entry so contributors know how to run the full test suite under Go's race detector. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13extract generic sortedWithState helper to deduplicate tab sort logicPaul Buetow
Four near-identical sorted-rows functions (sortedFileSnapshots, sortedDirSnapshots, sortedSyscallSnapshots, sortedProcessTableRows) each repeated the same guard-clone-sort-tiebreak-apply pattern. Replace them with a single generic sortedWithState[T,K] in sort.go that accepts per-tab byKey and tiebreak comparators as parameters. Remove now-unused slices imports from syscalls.go and processes.go. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13refactor: 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>
2026-05-13use errgroup instead of WaitGroup for concurrent snapshot buildersPaul 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.

2026-05-13perf: replace string += concatenation with strings.Builder in TUI render hot ↵Paul Buetow
paths Swap out ad-hoc += string concatenation in the flamegraph toolbar/status lines, dashboard filter summary, bubble/treemap status lines, eventstream view, processes tab, and probes list for strings.Builder, eliminating redundant allocations on every render tick. Also update dashboard/model_test.go fake SnapshotSource implementations to match the updated interface signature. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13refactor(generate): replace classifySyscall switches with kindRegistry (OCP)Paul Buetow
Introduce kindregistry.go with a kindMeta struct (structName, enterAccepted) and a kindRegistry map keyed by TracepointKind. Replace the switch in isEnterRejected (codegen.go) and the switch in eventStructName (bpfhandler.go) with lookupKind registry lookups. Adding a new TracepointKind now only requires a single registry entry — no switch statements need to be touched. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
