📝 WalkthroughWalkthroughChangesThe PR adds an experimental performance benchmark for DevKit quality gates. It defines benchmark contracts, isolated fixture execution, platform timing, diagnostic normalization, CLI wiring, baseline parsing, tests, catalog registration, and reproduction documentation. Quality-gate performance benchmark
Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to The new quality-gate benchmark harness can currently accept incomplete or stale baselines and may fail or produce non-reproducible results on some platforms and repository sizes. Merge readiness is therefore moderate: the changes should receive explicit owner follow-up and the concrete correctness and portability issues should be resolved before relying on the recorded benchmarks.

Track the resolved quality-gate toolchain in the suite hashes.
The benchmark executes Biome, ESLint, and TypeScript from node_modules/.bin, but these hash inputs omit package.json and the resolved dependency lockfile. A tool upgrade can change the measured command while an existing checkpoint remains current.
Add the package manifest and resolved lockfile to the suite hash inputs. Include any repository runtime-version declaration that controls the benchmark runtime.

Vitest toHaveLength Set size support
💡 Result:
Vitest's toHaveLength matcher is designed to check for a.length property on an object and verify if its value matches the expected number [1][2]. Because the JavaScript Set object does not have a.length property (it uses the.size property instead), toHaveLength does not natively support Set objects [1]. To verify the size of a Set in Vitest, you should use the.toBe or.toStrictEqual matchers by accessing the.size property directly: expect(mySet).toHaveProperty('size', expectedSize); // OR expect(mySet.size).toBe(expectedSize);

Set explicit timeouts on the two experiment tests.
Each test creates git fixtures and spawns many supervised child processes: 3 calibration probes plus 26 samples in the first test, and 13 samples in the second. The default Vitest per-test timeout is 5000 ms, so these tests can fail on slower machines. Pass a timeout to it.

Sort diagnostics with a byte-stable comparison, not localeCompare.
localeCompare depends on the host ICU collation of the runner process. diagnosticDigest is published as cross-host evidence, so two hosts can record different digests for identical diagnostics. Use a plain lexicographic comparison and avoid mutating the input array.

Handle result.error and raise maxBuffer in command.
spawnSync returns stdout and stderr as null when the spawn fails, for example when the executable is missing. Line 30 then dereferences null and throws a TypeError, which hides the real cause.

Escape ? in globPattern.
? is a single-character glob wildcard. The current translation leaves it as a regex quantifier, so a?.mts matches paths it must not match, and a pattern that starts with ? produces an invalid RegExp. Translate it to [^/]. Consider also compiling each glob once instead of once per candidate path.

Use the digest key for full-clean fixture directories too.
Line 199 interpolates raw lane.id and contender.id into a filesystem path, while the local-staged branch uses persistentFixtureKey. Ids are validated as non-empty only, so a separator or .. in an id redirects the fixture directory. Reuse the digest key and keep plan.orderIndex as the suffix.
🛡️ Proposed fix
- const root = join(experimentRoot, 'full', `${lane.id}-${plan.orderIndex}-${contender.id}`);
+ const root = join(
+ experimentRoot,
+ 'full',
+ `${persistentFixtureKey(lane, contender)}-${plan.orderIndex}`,

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Handle 'bytes' in formatMetric. gate-engine/eval/render.mts falls through to raw numeric formatting, so byte metrics render as 2048 or 1.500 without a byte unit or scale. Add explicit byte formatting and a renderer test.
