[Low] Entry permission bits are no longer preserved

extractAllToAsync(targetPath, overwrite, keepOriginalPermission, callback) — keepOriginalPermission is omitted here and defaults to false. decompress applied each entry's archived mode to the extracted file; adm-zip will now write everything with the default 0o666 & ~umask.

Almost certainly irrelevant for videos, logs, screenshots and HTML reports, but it is a real behaviour change that falls out of the swap incidentally rather than deliberately.

Suggestion: Either confirm nothing in these archives needs its mode bits preserved, or pass it explicitly:

Suggested change
await zip.extractAllToAsync(filePath, /* overwrite */ true);
await zip.extractAllToAsync(filePath, /* overwrite */ true, /* keepOriginalPermission */ true);

Apply the Constants rule only to the new build fallback message.

The buildArtifacts.js message is a new winstonLogger.debug string. Define it in the appropriate Constants bucket and reference the constant.

The reporterHTML.js string is pre-existing. The change only moves the same text into the promise result, so no Constants change is required for that site.

[Low] Inline string vs the constants.js convention — confirming CodeRabbit, with one correction

CodeRabbit flagged this line against the repo rule that strings live in bin/helpers/constants.js. The rule reading is fair, but its premise is off: this is not "a new winstonLogger.debug string". The PR edits a pre-existing inline debug string of identical shape (Error unzipping with decompress, trying with unzipper. Stacktrace: ...) — only the library name changed. It is also a debug log rather than a user-visible message, which is what the convention targets.

So: valid under a strict reading, mischaracterized as new, and Trivial either way. Not a regression introduced by this PR.

Suggestion: Optional. Moving it into Constants is fine; leaving it is equally defensible and keeps the diff surgical.

Reviewer: CodeRabbit (confirmed)

[Medium] No unzipper fallback here, and adm-zip extraction is stricter than decompress

buildArtifacts.js keeps a unzipper.Extract fallback around its adm-zip call; this call site has none, so any extraction failure is a hard failure that sets ERROR_EXIT_CODE.

That matters a little more after this change, because adm-zip@0.6.1 is deliberately stricter than the decompress it replaces: it rejects duplicate entry names, enforces decompression size caps, and throws FILE_IN_THE_WAY if a symlink already occupies a target path. Anything tripping those degrades gracefully in buildArtifacts.js but fails outright here.

The asymmetry pre-dates this PR (decompress had no fallback here either), so this is a verify-and-dismiss item rather than a defect — report.zip is BrowserStack-generated and should be plain json+html.

Suggestion: Confirm during smoke-testing that a real report.zip extracts cleanly. If it is cheap, mirroring the unzipper fallback here would remove the asymmetry.
