## What's the problem this PR addresses? #7103 The fix in #7070 added a version gate for the EBADF fstat error: ```js export const HAS_BROKEN_FSTAT_FOR_ZIP_FDS = major > 25 || (major === 25 && minor >= 7); ``` However, the breaking change from [nodejs/node#61769](nodejs/node#61769) (`lib: reduce cycles in esm loader and load it in snapshot`) was backported to **Node v24.15.0**, causing the identical `EBADF: bad file descriptor, fstat` error on that version. Works on v24.14.1, fails on v24.15.0. ## How did you fix it? Widened the version gate to also cover Node 24.15+: ```js export const HAS_BROKEN_FSTAT_FOR_ZIP_FDS = major > 25 || (major === 25 && minor >= 7) || (major === 24 && minor >= 15); ``` ## Checklist - [x] I have read the [Contributing Guide](https://yarnpkg.com/advanced/contributing). - [x] I have set the packages that need to be released for my changes to be effective. - [x] I will check that all automated PR checks pass before the PR gets reviewed.

Attempts to fix the EBADF encountered due to patching fs by doing the whole read instead.
I did this to get my own changes past a client (i.e. convincing them it isn't me that is the issue); I'm not sure this is the right long term choice.

#7065
Can't load zipped CJS modules in Node 25.7+
How did you fix it?
Return the source of zipped files instead of letting Node read it. I basically just went off this comment: nodejs/node#62012 (comment)
I'm not certain this is the most desirable way to do this, and if it is I'm not sure if there are other places that will need additional fixes. My knowledge of the codebase makes this an uneasy 'this works for me' solution. I suspect that if it is a reasonable solution, there may be some deletion that can be done.
