# Frontend release check applied to a Node pagination fixture

Evidence mode: source inspection of the supplied JavaScript plus the recorded Node unit-test run. Inspection at 2026-09-24T07:26:38Z is in `skill-inspection.txt`; the original unmodified skill was read from `public/resources/skills/frontend-release-check/SKILL.md`. No HTML, CSS, rendered page, URL, or browser session was supplied.

The original skill's frontend release workflow is **partially applicable**. Its source-located finding and evidence-mode requirements fit the helper review. Its visible-control, accessibility, document, and responsive checks require a page or browser and cannot be completed on this fixture.

## Source-located findings

1. High — `original.js:3-4` uses `page` before validating it. With `page: 0`, the observed return is an empty page with `page: 0`, violating the supplied positive-integer contract. `corrected.js:2-4` rejects it with `RangeError`.
2. High — `original.js:4-7` slices before filtering. The observed first page for five alternating `open`/`closed` records contains only ID 1 even though ID 3 should fill the second slot. `corrected.js:9-16` filters first.
3. Medium — `original.js:13-14` counts the unfiltered array and permits `pageSize: 0`; that input produces raw `totalPages: Infinity`. `corrected.js:5-7,12,20` validates size and counts matches.

The local Node tests support those findings: original exit 1 with 1/6 pass; correction exit 0 with 6/6 pass. The exact logs are `original-test-output.txt` and `corrected-test-output.txt`. This is helper behavior, not a frontend release result.

## Applicable checks and remaining review

Within this evidence mode, the changed function, its input contract, source lines, direct reproduction values, and unit-test outcomes were checked. There are no visible controls or document metadata in the fixture to trace. Accessible names, labels, fragment targets, form relationships, keyboard operation, focus visibility, responsive overflow, contrast, and screen-reader behavior were not tested.

To perform the skill's full frontend review, supply the consuming page or component and a local running URL. Then trace the pagination controls to this helper, exercise page changes and filters in a browser, and record viewport, browser, action, and observed result. The Node pass cannot substitute for those checks.
