TanStack edges pretable by 0.3 ms on `filter-metadata` (within noise) but loses 2.1–2.3× on the other two. This is the strongest comparative wedge surfaced since the post-stub-era, and meaningfully sharper than the scroll wedge (~1.7× vs AG Grid + TanStack; MUI parity). @@ -77,33 +77,81 @@ docs/research/ { "adapterId": "pretable", "rows": [ - { "scriptName": "sort", "interactionLatencyMs": 16.5, "settleDurationMs": 16.8 }, - { "scriptName": "filter-metadata", "interactionLatencyMs": 16.0, "settleDurationMs": 16.7 }, - { "scriptName": "filter-text", "interactionLatencyMs": 17.7, "settleDurationMs": 16.6 } + { + "scriptName": "sort", + "interactionLatencyMs": 16.5, + "settleDurationMs": 16.8 + }, + { + "scriptName": "filter-metadata", + "interactionLatencyMs": 16.0, + "settleDurationMs": 16.7 + }, + { + "scriptName": "filter-text", + "interactionLatencyMs": 17.7, + "settleDurationMs": 16.6 + } ] }, { "adapterId": "ag-grid", "rows": [ - { "scriptName": "sort", "interactionLatencyMs": 58.3, "settleDurationMs": 9.2 }, - { "scriptName": "filter-metadata", "interactionLatencyMs": 49.9, "settleDurationMs": 15.5 }, - { "scriptName": "filter-text", "interactionLatencyMs": 50.0, "settleDurationMs": 16.7 } + { + "scriptName": "sort", + "interactionLatencyMs": 58.3, + "settleDurationMs": 9.2 + }, + { + "scriptName": "filter-metadata", + "interactionLatencyMs": 49.9, + "settleDurationMs": 15.5 + }, + { + "scriptName": "filter-text", + "interactionLatencyMs": 50.0, + "settleDurationMs": 16.7 + } ] }, { "adapterId": "tanstack", "rows": [ - { "scriptName": "sort", "interactionLatencyMs": 34.4, "settleDurationMs": 31.6 }, - { "scriptName": "filter-metadata", "interactionLatencyMs": 15.7, "settleDurationMs": 26.5 }, - { "scriptName": "filter-text", "interactionLatencyMs": 40.2, "settleDurationMs": 24.7 } + { + "scriptName": "sort", + "interactionLatencyMs": 34.4, + "settleDurationMs": 31.6 + }, + { + "scriptName": "filter-metadata", + "interactionLatencyMs": 15.7, + "settleDurationMs": 26.5 + }, + { + "scriptName": "filter-text", + "interactionLatencyMs": 40.2, + "settleDurationMs": 24.7 + } ] }, { "adapterId": "mui", "rows": [ - { "scriptName": "sort", "interactionLatencyMs": 35.0, "settleDurationMs": 25.0 }, - { "scriptName": "filter-metadata", "interactionLatencyMs": 33.4, "settleDurationMs": 25.0 }, - { "scriptName": "filter-text", "interactionLatencyMs": 33.3, "settleDurationMs": 25.0 } + { + "scriptName": "sort", + "interactionLatencyMs": 35.0, + "settleDurationMs": 25.0 + }, + { + "scriptName": "filter-metadata", + "interactionLatencyMs": 33.4, + "settleDurationMs": 25.0 + }, + { + "scriptName": "filter-text", + "interactionLatencyMs": 33.3, + "settleDurationMs": 25.0 + } ] } ] diff --git a/scripts/extract-interaction-summary.mjs b/scripts/extract-interaction-summary.mjs index ce2e579..f540daa 100644 --- a/scripts/extract-interaction-summary.mjs +++ b/scripts/extract-interaction-summary.mjs @@ -3,8 +3,7 @@ import { readdir, readFile, writeFile } from "node:fs/promises"; import { join } from "node:path"; const STATUS_DIR = "status"; -const OUT_PATH = - "status/milestones/2026-05-10-b2-sort-filter-summary.json"; +const OUT_PATH = "status/milestones/2026-05-10-b2-sort-filter-summary.json"; const ADAPTERS = ["pretable", "ag-grid", "tanstack", "mui"]; const SCRIPTS = ["sort", "filter-metadata", "filter-text"]; @@ -14,9 +13,7 @@ function median(xs) { const sorted = [...xs].sort((a, b) => a - b); const n = sorted.length; if (n === 0) return null; - return n % 2 - ? sorted[(n - 1) / 2] - : (sorted[n / 2 - 1] + sorted[n / 2]) / 2; + return n % 2 ? sorted[(n - 1) / 2] : (sorted[n / 2 - 1] + sorted[n / 2]) / 2; } const files = await readdir(STATUS_DIR); @@ -42,9 +39,7 @@ for (const adapterId of ADAPTERS) { .slice(-3); const samples = []; for (const f of matchingFiles) { - const data = JSON.parse( - await readFile(join(STATUS_DIR, f), "utf8"), - ); + const data = JSON.parse(await readFile(join(STATUS_DIR, f), "utf8")); const lat = data.metrics?.interaction_latency_ms; const settle = data.metrics?.settle_duration_ms; if (typeof lat === "number" && typeof settle === "number") { diff --git a/status/milestones/2026-05-10-b2-sort-filter-summary.json b/status/milestones/2026-05-10-b2-sort-filter-summary.json index c62ea72..89fd7b6 100644 --- a/status/milestones/2026-05-10-b2-sort-filter-summary.json +++ b/status/milestones/2026-05-10-b2-sort-filter-summary.json @@ -4,11 +4,7 @@ "scenarioId": "S2", "scale": "hypothesis", "browserName": "chromium", - "scripts": [ - "sort", - "filter-metadata", - "filter-text" - ], + "scripts": ["sort", "filter-metadata", "filter-text"], "adapters": [ { "adapterId": "pretable",
