2026-02-21	Verify harness handles workload crash/nonzero exit (task 343)	Paul Buetow
	Add crash scenario to ioworkload that exits non-zero, and a test verifying the harness returns a clear error mentioning 'workload', reports a valid PID, and returns no records. Amp-Thread-ID: https://ampcode.com/threads/T-019c815e-6fb6-714a-a4db-37522416ea9a Co-authored-by: Amp <amp@ampcode.com>
2026-02-21	Add io_uring integration tests and workload scenarios	Paul Buetow
	Implement iouring_test.go with tests for io_uring_setup, io_uring_enter, and io_uring_register tracepoints. Add corresponding workload scenarios using raw syscalls (425, 426, 427) since Go stdlib doesn't wrap io_uring on amd64. - iouring-setup: creates io_uring instance via io_uring_setup(2) - iouring-enter: creates ring, calls io_uring_enter(2) with zero ops - iouring-register: creates ring, calls io_uring_register(2) with PROBE Task #343 Amp-Thread-ID: https://ampcode.com/threads/T-019c8149-2aa6-75fb-88f3-dd6bd3a2b654 Co-authored-by: Amp <amp@ampcode.com>
2026-02-21	Implement truncate_test.go + workload scenarios for truncate, ftruncate	Paul Buetow
	- truncate-basic: tests SYS_TRUNCATE (path-based) via syscall.Truncate - truncate-ftruncate: tests SYS_FTRUNCATE (fd-based) via syscall.Ftruncate - Both syscall wrappers use direct SYS_* calls on amd64 (no *at wrapping) Task #343 Amp-Thread-ID: https://ampcode.com/threads/T-019c8145-7437-7218-95ff-4cb451e18655 Co-authored-by: Amp <amp@ampcode.com>
2026-02-21	Implement sync_test.go + workload scenarios for fsync, fdatasync, sync, ↵	Paul Buetow
	sync_file_range - Add syncFdatasync, syncSync, syncSyncFileRange scenario functions - Register sync-fdatasync, sync-sync, sync-sync-file-range in scenarios map - Add sync_test.go with tests for all 4 sync-related syscalls - sync is a null_event (no path); others are fd_events - All use direct SYS_* syscalls on amd64 (no wrapper delegation) Task: #343 Amp-Thread-ID: https://ampcode.com/threads/T-019c813f-e020-7558-86ce-be6fdbd96f98 Co-authored-by: Amp <amp@ampcode.com>
2026-02-21	more on integration tests	Paul Buetow

2026-02-21	Add integration test framework: plan, workload binary, harness scaffolding	Paul Buetow
	- INTEGRATIONTESTS-PLAN.md: full design for e2e integration tests - integrationtests/cmd/ioworkload: standalone binary with 13 I/O scenarios - integrationtests/expectations.go: ExpectedEvent type and assertion helpers - integrationtests/parse.go: .ior.zst parser producing TestResult - Export IterRecord and LoadFromFile in flamegraph package - Fix TraceId -> TraceID, StringByName returns error instead of panic Amp-Thread-ID: https://ampcode.com/threads/T-019c8031-c106-757a-95a0-7a5457163ce7 Co-authored-by: Amp <amp@ampcode.com>
