Verdict: pretable filter-text is real-over-budget (16.79 ± 0.31 ms at n=20); tanstack vs pretable filter-metadata is noise-tied (1.6 ms mean diff vs 23 ms 2σ noise floor — tanstack's σ at n=8 is 11.6 ms). Incidental finding: pretable filter-metadata is also over budget at the mean (17.51 ± 2.44 ms). PR #131's 16.0 ms n=3 reading was a low-end sample. Homepage prose claims filter-metadata is "clear of" the single-frame budget; that's no longer accurate. Three recommendations queued (editorial cleanup + perf-fix investigation); see memo for details. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Summary
Tightens PR #131's two borderline numbers via n=20 re-run. No auto-merge — real-over-budget verdict on pretable filter-text requires editorial review.
Incidental finding: pretable
filter-metadatais also over budget at the mean (17.51 ± 2.44 ms at n=20). PR #131's 16.0 ms n=3 reading was a low-end sample.Full data
Recommendations (in the memo)
/benchpage prose: move filter-text + filter-metadata out of the "clears the budget" set.All four are editorial / scoping decisions the user should weigh in on before any homepage change ships.
Matrix wall-clock note
Original matrix flaked at ~22% (PR #133 had the same pattern); ran a follow-up tanstack-only matrix that also flaked early. Final sample counts: pretable 20+20, tanstack 8+6. Tight enough for unambiguous verdicts.
