bench: calibrate the paired Nightly comparison from A/A and slowed-bench runs - #7928
Advances quest/m1/bench-ci.md: calibrates the paired Nightly comparison for the rust-shared, rust-extra, rust-uring and rust-relay groups, and rewrites the quest to what remains.
Problem
The paired gate's threshold (10%), confirmation budget (20) and round count (3) were starting guesses. The quest needed A/A runs on the hosted ARM runners and a deliberately slowed bench to show whether they hold.
Runs
A/A 41921320690 (cancelled by Nightly's concurrency group after its bench artifacts uploaded) and 41933525520: neither confirmed a regression. Screen crossings of 10% either way: shared 18 and 26 of 716, extra 10 and 15 of 460, uring 1 and 1 of 41. rust-bench and rust-relay hit the delivery-batch bug moq-dev/moq#7940 fixed.
Slowed bench 41979277343: main at c150456928 against a base whose pattern-algebra/collect-literal/256 collects 192 of its 256 literals. The shared job failed at its gate with that case alone: screen +35.7%, rounds +34.6, +35.1, +35.2%. Its rounds also agreed at +9.3 to +9.7% on three source-identical stats/tick/*_10pct cases.
Relay: 15 and 37 of 410 crossed, 2 and 14 slower, nothing confirmed. Artifact-root paired.json present in both. Calibrated.
Shared, extra, uring: 20/19 of 728, 7/8 of 514/532, 3/2 of 41 crossed, nothing confirmed in the second run. The first failed the shared gate on wire_decode/padded/packets_64: screen +10.3%, rounds +11.9, +12.9, +12.1%, with the same commit on both sides. That case read +2.1% in the second run and -0.8 to +6.2% in the three earlier ones, so the bias moves with the build or run, not the source.
rust-bench: cancelled at its 60-minute timeout in both runs, with no artifact. Building both sides took 16 to 18 minutes. Confirmation rounds then reran benches whose untimed setup dominates: a round side of interests/covered/1000w_1000s took 2 minutes and publisher_covered_before_start/wake/8192 took 8, against about 3 seconds of measurement. Both build their fixture in the bench_function closure, which Criterion calls once per sample.
Approach
bench/README.md: record the calibration in the paired section, list rust-relay among the paired groups, and say each paired revision needs its own Cargo target directory (planned 2026-10-28).
.github/workflows/nightly.yml: a report-only matrix flag skips the gate step; rust-shared sets it until the build bias is fixed, so its confirmed regressions show on the site without failing Nightly. The README says so.
bench/compare.py: replace the "loose until A/A" comment with why the threshold cannot go lower.
quest/m1/bench-ci.md: rewritten to what remains: make rust-bench's leg fit its hour (fixture setup once per benchmark, rounds bounded by time if still needed), then its A/A run (authorized), and find the source of the build bias. The spent wait on fix(net): keep benchmark delivery batches readable #7940 is replaced by that item.
Choices made without asking
No second slowed-bench run. The authorization allowed one, but 41979277343 already showed the gate fails on a real slowdown, and every paired group runs the same gate step.
bench/run.sh does not pin glibc's malloc thresholds for every target. The largest A/A screen outliers (moq-mux/containers' ts_si_*, +35 to +49%) were each rejected by rounds, and a harness-wide pin would shift every trend line and measure an allocator production does not run.
Took the PR out of the merge queue (see the comment) so this calibration lands with it rather than in a second PR.
Decisions
✅ Decided 2026-11-05 (maintainer, /quest-unblock): authorize two A/A Nightly runs and one slowed-bench run on main after fix(net): keep benchmark delivery batches readable #7940 merged, replacing the earlier one-run authorization. The two A/A runs were dispatched; the slowed run was not needed (above).
✅ Decided 2026-11-05 (maintainer): rust-shared's gate is report-only until the build bias is fixed, after the first post-fix(net): keep benchmark delivery batches readable #7940 A/A run confirmed a false +12.1% that rounds cannot filter, since they rerun the same two binaries. The threshold stays at 10%. Not chosen: keeping the gate failing at 10%; raising it to about 15%.
✅ Decided 2026-11-05 (maintainer): authorize one rust-bench A/A Nightly dispatch once its leg fits its hour, replacing the quest's Maintainer: wait.
20 confirmations, 3 rounds and no harness-wide malloc pin remain as decided.
Follow-ups
moq-json's table/deltas/1%/{10000,20000} is bimodal in the quick screen (up to +646% in run 42119312487, rejected by rounds); the trend history for those cases is unusable. Already planned in quest/m1/bench-json-deltas.md.
Impact
Public API: none. Wire: none.
Validation
quest gate nix develop --command just check: pass on 7382ea2ec1, and again on 0e87d9263c after the report-only change.
quest check and quest check --base origin/main: pass.
Findings: none in any of the three rounds. Round 3 covered the report-only change. Round 2 covered pullfrog's two suggestions, applied: a Maintainer wait for the rust-bench A/A dispatch with the dated 2026-11-05 authorization, and the epic line naming rust-bench.
The OpenAI review on 3e6511ba61 reported no findings.
Two A/A Nightlies and one deliberately slowed-bench Nightly hold the
10% threshold, 20 confirmations and 3 rounds for the shared, supplemental
and io_uring groups. Record them, and leave the quest to the moq-net and
relay groups and the bias that makes rounds agree on unchanged code.

Calibrate the paired nightly benchmarks
bench: calibrate the paired Nightly comparison from A/A and slowed-bench runs
Nov 5, 2026
No actionable comments were generated in the recent review.
Walkthrough
The changes update paired benchmark documentation with A/A measurements, threshold and confirmation results, and remaining calibration work. They add rust-relay to the documented previous-commit build groups and specify separate Cargo target directories for base and current revisions. Quest requirements specify an hour limit for rust-bench and require A/A runs. The updated calibration record reports that rust-bench timed out before artifact upload.
Merge Risk: Minimal · up to 7382e
The update records benchmark results and remaining work without changing gate behavior. No merge-blocking risk was identified.

bench/README.md — records the paired comparison's calibration: two A/A runs on the shared/supplemental/io_uring groups, one deliberately slowed run, and the stable bias on unchanged code that makes 10% a floor. Also documents the per-revision Cargo target directories.
bench/compare.py — comment only; THRESHOLD_PCT, CONFIRMATIONS and the round count are unchanged.
quest/m1/bench-ci.md — rewritten to the remaining work: an authorized A/A dispatch for rust-bench/rust-relay after bench-test-mode lands, and locating/fixing the bias on unchanged code before lowering the threshold.
quest/m1/README.md — epic line now describes the remaining scope.
I checked the stated numbers against the bench-rust* artifacts of runs 41921320690, 41933525520 and 41979277343: screen crossings 18/26 of 716, 10/15 of 460 and 1/1 of 41, at most 17 slower, largest agreed round median +5.6% (the io_uring web_headers case); the slowed run's single confirmed regression at +35.7% screen with rounds +34.6/+35.1/+35.2, and the three stats/tick/*_10pct cases at +9.3..+9.7% with every round positive, while those same cases sat within ±4.6% in both A/A runs. 66bdf0dbbe is one commit ahead of c150456928 and touches only rs/moq-pattern/benches/matching.rs (256→192 literals), so the source-identical claim holds too. The job durations (18m58s to 44m16s) round to the stated 19 to 44 minutes.

bench/README.md — now names run.sh's BENCH_BASE for ad-hoc A/B comparisons, and the uncalibrated groups by recipe (rust-bench, rust-relay).
bench/compare.py — threshold rationale now says calibrated groups reached +9.7% on unchanged code, rust-bench/rust-relay still need A/A, and lowering waits on the bias fix.
quest/m1/bench-ci.md — records the 2026-11-05 maintainer authorization for one agent A/A dispatch after #7940 merges, with head_sha verification against bench-base and a warning to dispatch clear of the 07:00 UTC cron; the wait now requires an artifact-root paired.json; retains the earlier bias cases (#7139, #7253, moq-quic streams) when reading the remaining groups; records the agent decision not to pin glibc malloc thresholds harness-wide.
quest/m1/README.md — epic line now covers only the remaining scope.
I re-checked the operational details against the tree: nightly.yml declares a bench-base string input, cron: "0 7 * * *", and concurrency.group: nightly-${{ github.ref }} with cancel-in-progress: true, so the dispatch/cancellation wording and the A/A recipe names are accurate; sh/gh/nightly.sh resolves a bench-base revision through git rev-parse, so passing main's head works. All three prior threads are fixed and resolved.

quest/m1/bench-ci.md — the CodSpeed decision now says runs are limited to main pushes that touch Rust, Cargo, or Nix files, replacing the "every main commit" claim CodeRabbit flagged.
Merge of origin/main — brings in main's rs/moq-net, js/watch, flake.nix and quest changes; the PR's own four files are unchanged by it, per the range-diff.
I checked the new wording against .github/workflows/codspeed.yml: the trigger is push on main filtered to rs/**, the root Cargo.toml/Cargo.lock, flake.nix/flake.lock and the workflow file, with workflow_dispatch still gated on github.ref == 'refs/heads/main' and no gate on the run. The sentence is an accurate shorthand for those paths, so the calibration claim that CodSpeed is a supplementary signal beside the paired gate still holds. All three prior threads remain resolved.
Took this out of the merge queue. The maintainer authorized (2026-11-05, /quest-unblock) two A/A Nightly runs on main now that moq-dev/moq#7940 has merged, with the calibration recorded in this PR. Pushing that would drop the PR from the queue anyway. A/A run 1 is 42102235726, on 62ae716265. The PR goes back to ready with a fresh review once both runs are recorded.
Relay is calibrated; shared confirmed one false alarm at +12% on an

No actionable findings. Compared with the prior review at 94474a0 and the current base. The new documentation distinguishes relay calibration from the still-incomplete rust-bench group and explicitly records the shared group's same-commit +12.1% false alarm. The direction is sound: retain the current gate parameters while fixing expensive untimed setup and isolating build/run-placement bias. This PR changes documentation and comments, not gate behavior.
Verification: GitHub-only static review of the diff, relevant benchmarks/workflow/harness, prior findings, and sampled logs from both new A/A runs. The logged BENCH_BASE values match the run heads; both relay gates pass, the first shared gate reports the stated false alarm, and rust-bench times out with the documented long confirmation samples. I did not run tests or benchmarks or independently recompute every artifact statistic. Quest passed; Check was still running at final inspection.

Post-#7940 A/A evidence — records the two dispatched A/A runs (62ae716265, 83d0bc46ba) with head_sha equal to bench-base, their per-group crossing counts, and the one false confirmation (wire_decode/padded/packets_64 at +12% in the rounds, +2% in the next run).
bench/README.md — replaces "2 to 4%" with the six-run range, lists rust-relay among the paired groups, and states that separate builds of the same source can measure up to 12% apart, so 10% cannot go lower until that bias is fixed.
bench/compare.py — comment now explains the 12% bias instead of the old "loose until A/A" wording; threshold and confirmation budget unchanged.
quest/m1/bench-ci.md — adds rust-relay to the calibrated groups, records the 10%-stays decision, describes the bias as moving between runs rather than following the source, and rewrites the remainder around rust-bench's 60-minute timeout with the fixture-in-closure cause and the "pay setup once, bound rounds by time" fix.
quest/m1/README.md — epic line narrowed to the remaining rust-bench leg and the bias.
I re-derived the new numbers from the bench-rust* artifacts of runs 42102235726 and 42119312487: crossings are shared 20/19 of 728, extra 7/8 of 514/532, uring 3/2 of 41 and relay 15/37 of 410, the slowest group has 17 slower crossings, and every artifact-root paired.json has commit equal to base. wire_decode/padded/packets_64 screens +10.3%, its round means are +11.85/+12.85/+12.13 and it reads +2.06% in the second run against +5.38/-0.84/+6.23% in the three earlier runs. bench-rust is absent from both new artifacts and its job is cancelled at 60m, so the timeout claim holds; interests/covered, publisher_covered_before_start and track_evict_fanout match their described setup placement.
No actionable findings in the delta from 3e6511b. Both new review suggestions are addressed: the pending rust-bench A/A dispatch is again an explicit Maintainer wait, the prior authorization is recorded as spent for A/A runs, and the epic names the full rust-bench recipe. This keeps the next dispatch dependent on fresh authorization without changing the calibration conclusions or gate behavior.

quest/m1/bench-ci.md — ## Waiting is back with one Maintainer: item authorizing a single A/A Nightly dispatch for rust-bench, carrying the agents-dispatch-only-under-recorded-authorization rule and an evaluable Check: a dated authorization in this Plan.
quest/m1/bench-ci.md — the 2026-11-05 maintainer authorization is recorded as a dated Plan decision: two A/A runs plus one slowed-bench run after #7940, the A/A runs spent it, and the slowed run was not needed because every paired group runs the same gate step (the rationale moved here from the slowed-run bullet).
quest/m1/bench-ci.md — the goal now names rust-bench and the remaining bias rather than the already-spent calibration, and the plan's closing sentence no longer points at a dispatch that ## Waiting now owns.
quest/m1/README.md — epic line names the rust-bench recipe instead of "moq-net's paired group".
Both prior threads are addressed and resolved: the pending dispatch is visible to /quest-unblock again, the authorization behind the recorded runs is recoverable from the dated Plan decision, and the epic matches what the recipe actually runs (moq-net, net-cpu, kio, moq-gst). The new wait's Check is a state a later run can inspect, and the wording stays consistent with the recorded run evidence and bench/README.md.

[P2] Keep unavailable comparisons failing in report-only mode
This skips the only failure check for an unavailable comparison as well as the regression check. In bench/run.sh, a failed base build/run or confirmation is recorded in paired-unavailable.tsv while the measurement can still return success; sh/gh/bench-report.py:gate() is what fails on comparison["unavailable"]. Consequently, if rust-shared's current targets succeed but its base fails to build or run, this change makes the job green without a valid paired comparison, contrary to the retained README/quest rule that such targets fail Nightly. Keep invoking validation and suppress only the confirmed-regression failure in report-only mode, with coverage for an unavailable base.

ℹ️ No critical issues — the report-only switch works as designed, but it also silences the gate's "comparison could not run" failure, and the docs still promise that one.

bench/README.md — the paired section says rust-shared is report-only until the build bias is fixed.
quest/m1/bench-ci.md — the maintainer's rust-bench A/A dispatch authorization becomes a dated Plan decision (removing ## Waiting, since no human action is pending), the 10%-stays note becomes the report-only decision with its restore condition, and the goal closes on restoring rust-shared's gate.
I checked the mechanism end to end: bench/compare.py --criterion-paired never exits nonzero on a regression verdict, so the gate step is the only failure path after the upload, and benchmark-site's prepare/publish reads the uploaded paired.json regardless of the gate, so confirmed regressions still reach the site. matrix.report-only follows the same absent-key pattern as the existing !matrix.uncached at line 212.
The reason will be displayed to describe this comment to others. Learn more.
report-only skips the whole gate step, so it also silences the non-regression half of gate: sh/gh/bench-report.py:131 exits nonzero for comparison["unavailable"] too, which is how a base build failure, a base run failure, or a failed confirmation surfaces (and a missing paired.json raises as well). rust-shared is the largest paired group, so its whole comparison could stop being produced with Nightly still green, and both bench/README.md:902 and the 2026-10-23 decision at quest/m1/bench-ci.md:127 still say a target the base cannot build or run fails the job — the new sentence at bench/README.md:904 only exempts confirmed regressions.
Technical details
# Keep the unavailability failure under report-only## Affected sites-`.github/workflows/nightly.yml:241` — `!matrix.report-only` skips the entire `benchmark-report gate` invocation
-`sh/gh/bench-report.py:131` — `gate()` returns 1 for `regressions or comparison["unavailable"]`; `unavailable` covers base build/run and confirmation failures, and a missing `paired.json` raises
-`bench/README.md:902` — "A target the base cannot build or run fails the job too"
-`quest/m1/bench-ci.md:127` — the retained 2026-10-23 decision says the same
## Required outcome-`rust-shared` still fails Nightly when its comparison cannot run (unavailable targets, no `paired.json`), or the README and quest say explicitly that report-only covers those too.
## Suggested approach- Add a `--report-only` flag to `bench-report.py gate` that ignores `verdict == "regression"` but still counts `unavailable` and a missing `paired.json` toward the exit code, and pass `${{ matrix.report-only && '--report-only' || '' }}` from the workflow.

Advances
quest/m1/bench-ci.md: calibrates the paired Nightly comparison for therust-shared,rust-extra,rust-uringandrust-relaygroups, and rewrites the quest to what remains.Problem
The paired gate's threshold (10%), confirmation budget (20) and round count (3) were starting guesses. The quest needed A/A runs on the hosted ARM runners and a deliberately slowed bench to show whether they hold.
Runs
rust-benchandrust-relayhit the delivery-batch bug moq-dev/moq#7940 fixed.mainatc150456928against a base whosepattern-algebra/collect-literal/256collects 192 of its 256 literals. The shared job failed at its gate with that case alone: screen +35.7%, rounds +34.6, +35.1, +35.2%. Its rounds also agreed at +9.3 to +9.7% on three source-identicalstats/tick/*_10pctcases.62ae716265) and 42119312487 (83d0bc46ba), dispatched after fix(net): keep benchmark delivery batches readable #7940 merged under the maintainer's 2026-11-05 authorization. Each run'shead_shamatched itsbench-base.paired.jsonpresent in both. Calibrated.wire_decode/padded/packets_64: screen +10.3%, rounds +11.9, +12.9, +12.1%, with the same commit on both sides. That case read +2.1% in the second run and -0.8 to +6.2% in the three earlier ones, so the bias moves with the build or run, not the source.rust-bench: cancelled at its 60-minute timeout in both runs, with no artifact. Building both sides took 16 to 18 minutes. Confirmation rounds then reran benches whose untimed setup dominates: a round side ofinterests/covered/1000w_1000stook 2 minutes andpublisher_covered_before_start/wake/8192took 8, against about 3 seconds of measurement. Both build their fixture in thebench_functionclosure, which Criterion calls once per sample.Approach
bench/README.md: record the calibration in the paired section, listrust-relayamong the paired groups, and say each paired revision needs its own Cargo target directory (planned 2026-10-28)..github/workflows/nightly.yml: areport-onlymatrix flag skips the gate step;rust-sharedsets it until the build bias is fixed, so its confirmed regressions show on the site without failing Nightly. The README says so.bench/compare.py: replace the "loose until A/A" comment with why the threshold cannot go lower.quest/m1/bench-ci.md: rewritten to what remains: makerust-bench's leg fit its hour (fixture setup once per benchmark, rounds bounded by time if still needed), then its A/A run (authorized), and find the source of the build bias. The spent wait on fix(net): keep benchmark delivery batches readable #7940 is replaced by that item.Choices made without asking
bench/run.shdoes not pin glibc's malloc thresholds for every target. The largest A/A screen outliers (moq-mux/containers'ts_si_*, +35 to +49%) were each rejected by rounds, and a harness-wide pin would shift every trend line and measure an allocator production does not run.Decisions
mainafter fix(net): keep benchmark delivery batches readable #7940 merged, replacing the earlier one-run authorization. The two A/A runs were dispatched; the slowed run was not needed (above).rust-shared's gate is report-only until the build bias is fixed, after the first post-fix(net): keep benchmark delivery batches readable #7940 A/A run confirmed a false +12.1% that rounds cannot filter, since they rerun the same two binaries. The threshold stays at 10%. Not chosen: keeping the gate failing at 10%; raising it to about 15%.rust-benchA/A Nightly dispatch once its leg fits its hour, replacing the quest'sMaintainer:wait.Follow-ups
