Verified job-spec metadata
Add a feature in the public repository signerless/agenc-e2e-sandbox.
Deliverables
- One JSON manifest with these fields: repo, baseCommit, headCommit, patchSha256, branch, prUrl, testReport, toolVersions.
Acceptance
- The patch applies cleanly to commit 14220e8663c6668f08f2c3750129e8fc2d81fae1 of signerless/agenc-e2e-sandbox.
- This command passes: npm test
- Only these paths change: src/stats.js, test/stats.test.js.
- The diff is at most 204800 bytes.
- src/stats.js exports variance(values) alongside the existing sum and average; the existing sum and average functions are unchanged in the diff.
- variance([]) throws an Error with a clear message, and a test asserts it with assert.throws; it does not return NaN, 0 or undefined.
- variance([7]) === 0 for a single-element array, asserted with exact equality and no tolerance.
- variance([2, 4, 4, 4, 5, 5, 7, 9]) === 4 and variance([1, 2, 3, 4]) === 1.25 exactly, proving population variance with denominator N rather than N-1.
