In real local/workstation mode, the same benchmark name must regress on the script's second benchmark attempt before the gate exits red; a first-run-only regression, or disjoint first/second-attempt regression sets, is reported as local measurement noise and exits green. The retry is not a threshold change: both attempts compare against the same checked-in `bench/baseline.txt` with the same `-count=6`, `-cpu=1`, and parser, while compare-file mode remains single-pass so the self-test still proves a real >20% regression exits non-zero. The script runs the serial hot-path suite with `go test -run=^$ -bench=. -benchmem -count=6 -cpu=1`; do not remove `-cpu=1` unless a later explicit SOW proves the suite should measure multi-P scheduler behavior. Real benchmark runs emit compact diagnostics (Go version, effective `GOMAXPROCS`, benchmark CPU setting, package list, baseline/current paths, and load averages when available) so red local runs are auditable without exposing process command lines.

That branch passed the already-canceled lifecycle context + into `flushBatch`, allowing `BeginTx` to fail with context cancellation and + the in-memory batch to be cleared. Decision: real in-scope correctness issue; + fix in SOW-0050 with spec update, failing test, implementation patch, and + review rerun. +- Reviewer A and Reviewer B found stale SOW status text saying no production + code had been written. Decision: fixed in this SOW update. +- Reviewer A found stale exact `worker.go` line references in test comments. + Decision: remove exact line references in the delegated test cleanup. +- The Playwright E2E seed path then reproduced the same class of bug through + the channel-close branch: workers logged `flush (channel closed): begin tx: + context canceled` / `apply event ... context canceled`, leaving only 1 of the + expected 4 sessions seeded. Decision: extend the shutdown-drain fix so + producer-close final flushes always use the bounded drain context. + +### Round 2 - 2026-06-07 + +Findings: + +- Reviewer A found a remaining in-flight cancellation race: an active size or + interval flush can choose the lifecycle context while it is still live, then + receive shutdown cancellation before `BeginTx` or event application. The SQL + write can fail with context cancellation while `flushBatch` still clears the + in-memory batch. Decision: real in-scope data-loss risk; tighten the spec, + add a deterministic failing worker-runtime test, and fix context selection + before any completion claim. +- Reviewer A also found stale SOW text and an incomplete execution-log test list. + Decision: update the SOW as part of the same fix. +- Reviewers B and C did not find additional blocking issues. Decision: do not + treat clean secondary reviews as overriding Reviewer A's concrete race + evidence. + +### Round 3 - 2026-06-07 + +Findings: + +- Reviewer A found that the `context.WithoutCancel` fix prevents data loss but + leaves an active flush unbounded if shutdown arrives after context selection: + `WithoutCancel` drops `Done`, `Err`, and deadline, and `Ingester.Stop()` waits + for workers without its own timeout. Decision: real in-scope correctness issue; + keep the data-loss fix but replace plain `WithoutCancel` with a + lifecycle-detached write context that preserves values and starts the bounded + shutdown-drain timeout after parent cancellation. +- Reviewer B found no blocking issues. +- Reviewer C found only clarity findings around the intentionally ignored + `handleClose` context and the non-obvious cancellation-race test helper. + Decision: address clarity while fixing Reviewer A's blocking issue. +- Reviewer A found nearby ingester spec drift: the concurrency model still said + only in-memory tests pin `MaxOpenConns=1`, while `OpenWriter` pins writer + stores unconditionally. Decision: fix the spec text in this SOW because + `ingester.md` is already part of the touched contract surface. + +### Round 4 - 2026-06-07 + +Findings: + +- Reviewer A found spec drift: `ingester.md` claimed active worker write errors + also write `SourceErrorEvent` rows for `/api/health`, while normal ingester + workers only log/report batch failures. Decision: correct the spec to match + the existing contract. Do not add `SourceErrorEvent` persistence for worker + transaction failures in this slice because the same write path or database + failure may prevent reliable diagnostic persistence. +- Reviewer A found missing test coverage for the canceled-parent + shutdown-idle-refresh path. Decision: add a worker/runtime regression test + before any related implementation cleanup. +- Reviewer A found the short context-grace timing tests could be flaky under + heavy scheduler delay. Decision: lengthen the test grace values while keeping + watchdog timeouts bounded. +- Reviewers B and C found only low maintainability issues: make the + channel-close shutdown-drain decision visible in code, simplify timer + rearming, and make the custom test context safer for future concurrent use. + Decision: apply these cleanups before the next review rerun. + +### Round 5 - 2026-06-07 + +Findings: + +- Reviewer A found the corrected worker write-error spec still used stale + `opts.OnError` wording even though production workers report through + `worker.report`, using the private `onErr` seam only in tests and otherwise + `logger.Error`. Decision: real spec drift; corrected `ingester.md`. +- Reviewer A found the detached-context timing tests could still false-fail + under extreme scheduler delay because they made an immediate non-blocking + `Done` assertion after parent cancellation/deadline. Decision: make the tests + elapsed-time tolerant while preserving the invariant that the write context + must not cancel before the bounded grace has elapsed. +- Reviewers A and C found the cancellation-race test helper had non-standard + context semantics and made the race harder to reason about. Decision: replace + it with normal `context.WithCancel` semantics by selecting the write context + first, canceling the parent, then flushing with the already-selected write + context. +- Reviewer A found `internal/ingest/worker.go` still exceeded the project + file-size smell threshold after the function-complexity cleanup. Decision: + split worker runtime/lifecycle/timer/context orchestration into + `internal/ingest/worker_runtime.go`; `worker.go` now stays focused on worker + write/transaction helpers and is under 400 lines. +- Reviewer C noted `rearmTimer()` still runs after terminal shutdown flushes. + Decision: no code change in this slice; the rearm is immediately neutralized + by `workerRuntime.close()` and has no observable runtime effect. Avoiding it + would add shutdown-only branching for no behavior or gate benefit. + +### Round 6 - 2026-06-07 + +Findings: + +- Reviewer A found the SOW validation command still recorded Codacy only for + `worker.go` and `notify_producer.go`, omitting new production file + `worker_runtime.go`. Decision: real validation-record defect; reran Codacy on + all three touched production files and updated the validation evidence. +- Reviewer A found `BenchmarkBatchInsert` measures `worker.flush` directly and + therefore bypasses `workerRuntime.flushBatch` context selection. Decision: + document this intentionally. `BenchmarkBatchInsert` is the accepted benchmark + gate for this slice because it measures the throughput-critical SQL batch + transaction path already baselined in `bench/baseline.txt`; adding a new + benchmark without a historical baseline would not protect the existing + regression gate. The detached-context path is covered by focused unit/race + tests rather than benchmarked as a separate baseline in this slice. +- Reviewer A found stale validation text saying "after the Round 4 fixes". + Decision: corrected the pending-validation wording. +- Reviewer A found a stale `worker.go:221` reference in the batch-insert + benchmark comment. Decision: replaced the line-specific reference with + `worker.flush`. +- Reviewer B raised a possible detached-write goroutine linger. Decision: false + positive for the current implementation. If parent cancellation and write + cancellation race, the second `select` in `detachedWriteContext` still + observes `writeCtx.Done()` and exits; otherwise the goroutine is correctly + bounded by the shutdown grace while the write is still active. +- Reviewer C found the scheduler-tolerant test helper name imprecise. + Decision: renamed it to `probeContextNotCanceledBeforeGrace`. + +### Round 7 - 2026-06-07 + +Findings: + +- Reviewer A found the SOW validation plan still omitted `TestEmitNotify` in the + focused test regex and `internal/ingest/worker_runtime.go` in the strict + Lizard command, while the executed validation evidence already included both. + Decision: real SOW-only drift; corrected the validation plan and reran review + on the full staged diff. +- Final convergence review after that correction found no blocking correctness, + race, goroutine-leak, security, spec-drift, unwanted-side-effect, + performance, or maintainability issues. +- Reviewers noted only non-blocking observations already accepted in this SOW: + `handleClose` intentionally ignores the lifecycle context, terminal shutdown + flushes may rearm a timer that `workerRuntime.close()` immediately stops, and + `Ingester.Stop()` has no overall timeout outside the per-worker bounded drain. + +### Round 8 - 2026-06-07 + +Findings: + +- Reviewer A found stale ingester shutdown spec text promising a process-level + 15 s hard timeout and a 5 s worker drain timeout. The implementation has a + 5 s adapter-goroutine wait in the CLI and a 10 s per-worker write/drain + context, but no separate process-level hard timeout. +- Reviewer A found stale outcome text saying the final full aggregate gate was + green, while later SOW-0058 review fixes still required a fresh full gate. + +Resolution: + +- Corrected `.agents/sow/specs/ingester.md` to describe the actual shutdown + contract: adapter wait, per-worker bounded write/drain context, and no + process-level hard timeout in the current implementation. +- Corrected the outcome wording so SOW-0050 does not overstate the final gate + state before SOW-0058 review convergence and a fresh aggregate gate. + +### Round 9 - 2026-06-07 + +Findings: + +- Final broad review over the combined SOW-0050 and SOW-0058 diff returned no + blocking correctness, race, goroutine-leak, security, CI, spec-drift, + benchmark-gate, performance, or unwanted-side-effect findings. +- Reviewers noted only non-blocking observations already accepted in this SOW: + a future test could leak a shutdown-drain timer for up to 10 s if it constructs + a `workerRuntime` without `close()`, `pullPendingEvent` is defensive after + buffered-event draining, terminal shutdown may rearm a timer that `close()` + stops immediately, and one notify error wrapper is cosmetically different. + +Resolution: + +- Accepted the observations as non-blocking because current production and tests + close the runtime, the defensive select has no behavior impact, the terminal + rearm is neutralized by `close()`, and the error text remains contextual. + Proceeded to the fresh full aggregate gate. + +Artifact impact plan: + +- Specs: `ingester.md` gets flush-order hygiene for the first slice. Presenter, + pricing, store, data-model, security, and deployment specs are unaffected + unless later SOW-0050 slices touch their contracts. +- Runtime project skills: update only if a new permanent backend pattern + emerges. +- End-user docs: likely unaffected. +- SOW lifecycle: move to `current/` when activated. + +Open-source reference evidence: + +- This is internal backend maintainability work. External open-source evidence + is required only if a selected slice changes a protocol or dependency + behavior claim. + +Open decisions: + +- None for the operator. + +## Outcome + +Completed. The first implementation slice is hardened for bounded-context +lifecycle-cancellation findings, focused tests pass, package tests pass, +external review converged, and the final full aggregate gate passed on the +completed state. + +## Execution Log + +### 2026-06-07 + +- Activated the SOW and selected the first slice: + `internal/ingest/worker.go` plus `internal/ingest/notify_producer.go`. +- Updated `.agents/sow/specs/ingester.md` to document the current worker flush + order before tests or production code changed. +- Added characterization tests before refactoring: + - `TestWorker_CancelDrainsPendingBatch` + - `TestWorker_CancelDrainsBufferedChannel` + - `TestEmitNotify_MaterializedRollupInvalidatesStatsOnce` + - `TestRefreshRollups_RefreshOnlyNotifyErrorRollsBack` +- Refactored worker lifecycle/timer/shutdown orchestration, flush phases, + idle-refresh notify handling, and notify row emission helpers without + changing transaction order or notify semantics. +- Added review-driven shutdown tests: + - `TestWorkerRuntime_FlushBatchUsesShutdownDrainAfterLifecycleCancel` + - `TestWorkerRuntime_HandleCloseUsesShutdownDrainForFinalFlush` + - `TestWorkerRuntime_FlushBatchSurvivesLifecycleCancellationRace` +- Hardened worker write-context selection so active size/interval flush SQL is + detached from lifecycle cancellation, while already-observed shutdown and + channel-close final drains still use the bounded shutdown-drain context. +- Review round 3 hardened that design further: active writes must not be + unbounded after lifecycle cancellation.

Update `scripts/test/check-bench-test.sh` so it proves the new diagnostics + and `-cpu=1` policy are present without running the expensive benchmark + suite. +3. Stabilize `internal/notify/bench_test.go` by measuring a deterministic batch + of serial `Hub.Deliver` calls per benchmark operation instead of one + sub-microsecond/small-microsecond delivery per operation; continue reporting + deliveries/sec and subscriptions. +4. Regenerate `bench/baseline.txt` from the updated benchmark command and + replace the header with SOW-0058 provenance. +5. Run focused checks, then the full aggregate gate. +6. If the first full aggregate run still finds a benchmark-only false red, + update the benchmark gate to require reproduction in real workstation mode: + run the same benchmark suite a second time against the same baseline and + fail only if a >20% `sec/op` regression reproduces.

Investigate current benchmark gate and fixture instability. +2. Implement the smallest policy/tooling change that preserves strictness. +3. Re-run benchmark and full aggregate gates. +4. Run external review and record convergence. + +## Execution Log + +### 2026-06-07 + +- Filed from SOW-0050 validation after three aggregate gate failures on + unchanged adapter benchmarks and neutral changed ingest benchmark results. +- Activated as the SOW-0050 blocker. Technical decision: the benchmark suite is + a serial hot-path suite, so the local gate will pin `go test -cpu=1` and + refresh the workstation baseline under this explicit SOW rather than widening + the regression threshold or ignoring red aggregate gates. +- Implementation pass 1 changed `scripts/check-bench.sh`, + `scripts/test/check-bench-test.sh`, and `bench/baseline.txt`. Focused + self-test passed, but the implementer observed a freshly refreshed + `HubFanout` false red (`+23.19% sec/op`) followed by a pass without code + changes, and the refreshed baseline samples still ranged from 1062ns to + 1383ns. Decision: do not accept the first pass; stabilize the `HubFanout` + fixture and refresh the baseline again. +- Implementation pass 2 stabilized `HubFanout` with deterministic fixed-batch + serial `Deliver` operations and refreshed the baseline. Focused checks and one + standalone benchmark-gate run passed, but the full aggregate gate still + false-failed `HubFanout` once (`+28.32% sec/op`, current sample spread + `±24%`) while all previous gate sections passed. Decision: add a real-mode + reproducibility retry to the benchmark gate instead of accepting a noisy + single-run failure or refreshing the baseline again. +- Implementation pass 3 added the real-mode reproducibility retry while keeping + compare-file mode single-pass. Focused validation passed, the standalone + benchmark gate passed on attempt 1, and the full aggregate gate passed on + attempt 1. The retry path is covered by static self-test assertions and the + compare-file parser remains covered by synthetic benchmark fixtures. +- External review round 1 found two real fail-open defects in the shell gate: + Bash `errexit` can be disabled inside a function called through an OR-list, so + the real benchmark command must explicitly check and return on `go test` + failure; and compare-file mode accepted an empty baseline as a pass, so the + baseline must be required to be non-empty. The same review also found the + real-mode retry path was only statically asserted, not dynamically exercised. + Decision: fix all three before claiming SOW-0058 complete. +- External review round 1 also raised a possible benchmark-name suffix mismatch + because the refreshed baseline uses unsuffixed benchmark names. Verification: + `go test -run='^$' -bench=BenchmarkHubFanout -benchmem -count=1 -cpu=1 + ./internal/notify/` emits `BenchmarkHubFanout` without a `-1` suffix in the + current Go toolchain.

Decision: blocking; explicitly check the + benchmark command status inside the function and add a hermetic self-test. +- Reviewer A found a real fail-open defect: compare-file mode accepts an empty + baseline file as a pass because only current output is checked with `-s`. + Decision: blocking; require a non-empty baseline and add a self-test. +- Reviewers A and B found the real-mode retry path was only statically asserted, + not dynamically executed by the self-test. Decision: blocking because this is + a shared quality-gate contract; add a fake-`go`/fake-`benchstat` real-mode + self-test covering pass-after-retry, reproduced failure, and benchmark-command + failure. +- Reviewer C raised a possible `-cpu=1` benchmark-name suffix mismatch in the + baseline. Decision: false positive after direct verification; the current Go + toolchain emits unsuffixed benchmark names under `-cpu=1`, matching the + refreshed baseline. +- Reviewer B found only non-blocking maintainability observations around shell + globals, `go run` overhead in diagnostics, and the absolute/relative baseline + path split. Decision: accept for this SOW unless the blocking fix naturally + simplifies any of them. + +### Round 2 - 2026-06-07 + +Findings: + +- Reviewer A found a real false-red defect: the real-mode retry treated any + first-attempt regression plus any second-attempt regression as reproduced, + even when different benchmark names regressed on each attempt. Decision: + blocking; `scripts/check-bench.sh` now intersects first/second regression + benchmark names and exits red only for matching names. +- Reviewer A found a real fail-open baseline edge case: a non-empty + metadata-only baseline with no `Benchmark` rows was not explicitly rejected. + Decision: blocking; baseline validation now requires at least one parsed + benchmark row. +- Reviewer B found a low-portability shell cleanup issue under older Bash + `set -u` behavior when the temp-file array is empty. Decision: fix now because + the change is simple and improves fail-closed diagnostics. +- Reviewer C found `bench/README.md` still documented the raw baseline command + without `-cpu=1`. Decision: fix now so internal docs match the gate contract. +- Reviewer B raised a fake-`go` baseline-path concern. Decision: false positive; + real mode runs fake `go test` from the repository root, matching + `bench/baseline.txt`. +- Reviewer D timed out with no usable output and is not counted toward review + convergence. + +Resolution: + +- Fixed all accepted findings and reran focused validation plus the full + aggregate gate. Follow-up review uses the same broad scope plus these fix + notes. + +### Round 3 - 2026-06-07 + +Findings: + +- Reviewer A found two low documentation/status drift issues after the round 2 + fixes: `bench/README.md` did not yet mention the real-mode same-benchmark + retry contract, and SOW-0050 still implied more benchmark fail-closed fixes + were pending rather than review convergence. Decision: fix both because they + describe the shared gate contract and active SOW state. +- Reviewers B and C found no actionable findings. Reviewer D was not launched + in that round; the three usable reviewers satisfied the minimum review set. + +Resolution: + +- Updated `bench/README.md` and SOW-0050 status wording. Follow-up review kept + the same broad scope plus these fix notes. + +### Round 4 - 2026-06-07 + +Findings: + +- Reviewer A found a real CI blocker: `.github/workflows/ci.yml` `Require + benchmarks` still extracted required baseline rows only with a `BenchmarkName-N` + suffix, while the refreshed `-cpu=1` baseline emits unsuffixed + `BenchmarkName` rows. Impact: local gates could pass while CI failed before + the benchmark compile-smoke. Decision: blocking; update the workflow parser to + accept both suffixed and unsuffixed rows and self-test the live CI block. +- Reviewer A also found stale SOW validation text using `BatchInsert-16` and + `HubFanout-16` for post-`-cpu=1` benchmark runs. Decision: fix documentation + drift for the post-SOW-0058 runs while keeping older pre-SOW-0058 historical + evidence unchanged. +- Reviewers B, C, and D found no blocking issues and only non-blocking design or + documentation observations. + +Resolution: + +- Updated the CI `Require benchmarks` parser, added four hermetic self-tests for + unsuffixed, mixed, count-fail, and missing-function cases, updated the + quality-gate spec/skill contract, fixed the stale post-`-cpu=1` SOW benchmark + suffix text, and reran focused validation. Follow-up review must use the same + broad scope plus these fix notes. + +### Round 5 - 2026-06-07 + +Findings: + +- Reviewer A found a real test-strength gap: the detached write-context tests + proved the context was not canceled immediately after parent cancellation or + deadline, but did not assert elapsed time when `writeCtx.Done()` actually + fired. Impact: a regression canceling shortly after the immediate probe could + pass while violating the bounded-grace contract. Decision: fix the test gap. +- Reviewers B, C, and D found no blocking issues; their observations were + non-blocking design or maintainability notes. + +Resolution: + +- Strengthened `TestDetachedWriteContext` and + `TestDetachedWriteContextParentDeadlineStartsShutdownGrace` so they assert + `time.Since(graceStarted) >= grace` when `writeCtx.Done()` is observed, while + retaining the upper-bound watchdog. Focused non-race and race tests passed. + Follow-up review must use the same broad scope plus these fix notes. + +### Round 6 - 2026-06-07 + +Findings: + +- Reviewer A found stale shutdown contract text in `.agents/sow/specs/ingester.md` + and stale final-gate wording in SOW-0050. Impact: no implementation bug, but + the durable spec still promised a process-level 15 s hard timeout and 5 s + worker drain timeout while the current code provides a 5 s adapter wait, + 10 s per-worker write/drain contexts, and no separate process-level hard + timeout. Decision: fix the spec/SOW drift. +- Reviewers B, C, and D found no blocking code, CI, race, security, or + benchmark-gate findings. + +Resolution: + +- Corrected `.agents/sow/specs/ingester.md`, SOW-0050 outcome/status wording, + and the stale `shutdownDrainTimeout` code comment. Follow-up review kept the + same broad scope plus these fix notes. + +### Round 7 - 2026-06-07 + +Findings: + +- Reviewer A found SOW-only scope drift in this SOW: the pre-implementation + affected surfaces, artifact impact plan, and validation plan omitted the + later `.github/workflows/ci.yml` parser and `bench/README.md` changes. + Impact: no runtime or CI defect, but the durable SOW gate no longer fully + matched the final implementation scope. Decision: fix the SOW evidence before + completion. +- Reviewers B, C, and D found no blocking correctness, race, shutdown, + benchmark-gate, CI parser, security, test-strength, or spec-drift findings. + +Resolution: + +- Updated affected surfaces, spec deltas, implementation plan, validation plan, + artifact impact plan, and top-level SOW status wording so this SOW and + SOW-0050 no longer overstate completion before final review convergence and a + fresh full gate. Follow-up review must use the same broad scope plus these fix + notes. + +### Round 8 - 2026-06-07 + +Findings: + +- Final broad review over the combined SOW-0050 and SOW-0058 diff returned no + blocking correctness, race, goroutine-leak, security, CI, spec-drift, + benchmark-gate, performance, or unwanted-side-effect findings. +- Reviewers noted only non-blocking observations already accepted in this SOW: + a future test could leak a shutdown-drain timer for up to 10 s if it constructs + a `workerRuntime` without `close()`, `pullPendingEvent` is defensive after + buffered-event draining, terminal shutdown may rearm a timer that `close()` + stops immediately, and one notify error wrapper is cosmetically different. + +Resolution: + +- Accepted the observations as non-blocking because current production and tests + close the runtime, the defensive select has no behavior impact, the terminal + rearm is neutralized by `close()`, and the error text remains contextual. + Proceeded to the fresh full aggregate gate. + +## Outcome + +Completed. Review converged after the round 7 SOW scope-evidence fix, and the +fresh full aggregate gate passed on the final state. + +## Lessons Extracted + +SOW-0058 exposed that local benchmark-gate validation is not enough when CI has +secondary consumers of benchmark metadata. Any baseline-row shape change must +include a self-test for every parser that reads `bench/baseline.txt`, not only +the local regression gate. + +## Followup + +None. + +## Regression Log + +None yet. + +## PR Check Remediation - 2026-06-07 + +Remote Codacy analysis on PR #61 reported three ShellCheck SC2016 warnings in +`scripts/test/check-bench-test.sh`. The findings were valid style findings in +literal regex assertions. The remediation moved those regexes into +double-quoted variables with escaped literal dollar signs, preserving the same +assertions while satisfying ShellCheck. + +Follow-up review also found that default local ShellCheck reported SC2329 on the +benchmark gate's trap callback in `scripts/check-bench.sh`. The final cleanup +uses an array-aware trap command directly, avoiding an indirect cleanup function +and keeping the temporary-file cleanup behavior unchanged. + +PR review then found that benchmark command-failure diagnostics captured `$?` +after the `if` statement instead of inside the failing branch, so a failed real +`go test` benchmark could be reported with the wrong exit code. The fix captures +the status in the `else` branch and tightens the fake real-mode self-test to +require the expected `go test exit 42` diagnostic. + +Validation: + +- `bash -n scripts/test/check-bench-test.sh`: passed. +- `shellcheck scripts/test/check-bench-test.sh`: passed. +- `bash scripts/test/check-bench-test.sh`: passed, 41/41 assertions. +- `bash -n scripts/check-bench.sh scripts/test/check-bench-test.sh`: passed + after the trap cleanup. +- `shellcheck scripts/check-bench.sh scripts/test/check-bench-test.sh`: passed + after the trap cleanup. +- `bash scripts/test/check-bench-test.sh`: passed after the diagnostic-status + fix; the fake `go test` failure assertion now requires `go test exit 42`. +- Local Codacy analysis confirmed ShellCheck, Semgrep, and Trivy reported zero + issues for the touched shell scripts. +- Final local Codacy analysis after the diagnostic-status fix again reported + zero Trivy, Semgrep, and ShellCheck issues. The remaining 23 Lizard findings + are per-rule counts for pre-existing ingest test complexity and file-size debt + tracked by `SOW-0059`, not benchmark shell-script issues. +- Final reviewer rerun found no benchmark-script correctness, ShellCheck, + cleanup, security, retry-contract, or validation blocker.

If the production path is serial (for example SSE `Hub.Deliver` fanout), the benchmark fixture uses deterministic buffering/pre-seeding instead of background helper goroutines to keep the fast path open; otherwise the local workstation gate can fail on unchanged code under ordinary desktop/VM load. -- **`check-bench.sh` is a local/workstation gate**, not a CI gate: `bench/baseline.txt` is workstation-measured and is not comparable to GitHub-runner hardware. CI keeps the bench compile-smoke (`-benchtime=1x`, artifact-uploaded for trend) and runs the hardware-independent gate self-test; a runner-baselined CI regression gate is a deferred follow-up. `bench/baseline.txt` carries benchmark-code provenance (an implementing commit SHA when the benchmark code predates the baseline, or a same-commit `git blame` note when benchmark code and baseline land together) and the `goos/goarch/pkg/cpu` config lines (benchstat groups by config — baseline and current must share it). Baseline refresh requires an explicit SOW (no auto-update). +- `scripts/check-bench.sh` runs `go test -run=^$ -bench=. -benchmem -count=6 -cpu=1` over the 7 benchmark packages (11 benchmarks; adapter `Scan` + `Tail` share `aiagent_v2`, claude-code adapter `Scan` + `Tail` share `claude_code`, Codex adapter `Scan` + `Tail` share `codex`, and Opencode adapter `Scan` + `Tail` share `opencode`) and compares to `bench/baseline.txt` via `benchstat` (`-count=6` is benchstat's minimum for a 0.95 confidence interval). The baselined benchmarks are serial hot-path checks, so the gate pins Go's benchmark CPU list to `1` instead of inheriting workstation-wide `GOMAXPROCS` scheduler noise. +- Threshold: a **statistically-significant > 20% sec/op regression for any individual benchmark** fails the gate. In real local/workstation mode, the **same benchmark name** must regress on a second benchmark run before the gate exits red; a first-run-only regression, or disjoint first/second-attempt regression sets, is reported as a local-noise warning and the gate exits green. The retry does not widen the threshold, skip the benchmark suite, or refresh the baseline: both attempts use the same `bench/baseline.txt`, `-count=6`, `-cpu=1`, and `benchstat` parser. Compare-file mode (`scripts/check-bench.sh BASE CURRENT`) remains single-pass and fails immediately, so the hardware-independent self-test can prove a real >20% `sec/op` regression still exits non-zero. Only **sec/op** is gated — the custom `ReportMetric` values (B/s, events/sec, peak_heap_mb, …) are informational (peak_heap_mb is benchtime-sensitive), and the per-block `geomean` aggregate is excluded (a noisy benchmark moves it without any single benchmark significantly regressing). Self-tested by `scripts/test/check-bench-test.sh`. +- Fail-closed cases: missing, empty, or benchmarkless baseline, missing or empty current output, failed benchmark command, failed `benchstat`, a dropped/renamed baseline benchmark, or disjoint benchmark config groups all exit non-zero. `scripts/test/check-bench-test.sh` must dynamically exercise compare-file parser behavior and real-mode retry/error behavior with hermetic fakes, including disjoint first/second-attempt regression sets, without running the expensive benchmark suite. +- Gated benchmarks must measure the intended hot path without helper-goroutine scheduler noise in the timed region. If the production path is serial (for example SSE `Hub.Deliver` fanout), the benchmark fixture uses deterministic buffering/pre-seeding instead of background helper goroutines to keep the fast path open; otherwise the local workstation gate can fail on unchanged code under ordinary desktop/VM load. Very small serial hot-path benchmarks may amortize a deterministic fixed batch inside each benchmark operation when a single call is too small to be a stable local `sec/op` signal; they still report the per-hot-path-unit metric (for example deliveries/sec) so the underlying operation remains visible. +- Real benchmark runs print compact diagnostic context before measuring: Go version, effective `GOMAXPROCS`, benchmark `-cpu` setting, package list, baseline path, temporary current path, and `/proc/loadavg` values when available. These diagnostics do not change pass/fail status; they make a red local benchmark gate auditable without exposing process command lines or sensitive data. +- **`check-bench.sh` is a local/workstation gate**, not a CI gate: `bench/baseline.txt` is workstation-measured and is not comparable to GitHub-runner hardware. CI keeps the bench compile-smoke (`-benchtime=1x`, artifact-uploaded for trend) and runs the hardware-independent gate self-test; a runner-baselined CI regression gate is a deferred follow-up. `bench/baseline.txt` carries benchmark-code provenance (an implementing commit SHA when the benchmark code predates the baseline, or a same-commit `git blame` note when benchmark code and baseline land together), the exact benchmark command, and the `goos/goarch/pkg/cpu` config lines (benchstat groups by config — baseline and current must share them). Baseline refresh requires an explicit SOW (no auto-update); SOW-0058 refreshes the workstation baseline for the `-cpu=1` serial-hot-path contract. +- CI's `Require benchmarks` compile-smoke presence check extracts required + benchmark names from `bench/baseline.txt` and implemented benchmark names from + `*_test.go`. That extractor must accept both Go benchmark row forms: + suffixed rows emitted by multi-CPU benchmark runs (`BenchmarkName-N`) and + unsuffixed rows emitted by `-cpu=1` (`BenchmarkName`). It must normalize both + to the same logical benchmark name before comparing the expected 11 names. + `scripts/test/check-bench-test.sh` self-tests this CI parser contract so a + baseline refresh cannot make local gates green while CI fails on benchmark-row + shape. ### Go — Rollup Correctness Diff (SOW-0007) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 7892f36..8d0b293 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -367,9 +367,11 @@ jobs: run: | set +e required="$( - grep -E '^Benchmark[A-Za-z0-9_]+-[0-9]+' bench/baseline.txt \ - | awk '{print $1}' \ - | sed -E 's/-[0-9]+$//' \ + awk '$1 ~ /^Benchmark[A-Za-z0-9_]+(-[0-9]+)?$/ { + name = $1 + sub(/-[0-9]+$/, "", name) + print name + }' bench/baseline.txt \ | sort -u )" required_ec=$? diff --git a/bench/README.md b/bench/README.md index 53f64ab..73c4fce 100644 --- a/bench/README.md +++ b/bench/README.md @@ -85,12 +85,14 @@ evidence in the SOW Chunk 9 entry but is not the SOW gate metric. ## `bench/baseline.txt` Frozen baseline consumed by `benchstat` via `scripts/check-bench.sh`.
