Because they need to be fingerprinted to allow immutable caching. Even if a single character in a file is changed, the hash of all files that depend on that file will change.

but i didn`t change any file。but when repeat build this project , the resource has changed.

[brc-dd]

Sorry. Did you rename or move any file? Can you share your repo or create some dummy one to show the example? Can you share those two metadata files?

[Perrywzp]

i think you can try init a clean project , create sidebar like under picture.

and add metadata props in themconfig or not. then try repeat build , compare the resource , you will find a lot of changed files。like html or like metadata.[hash].js
