Description
Reproduction link or steps
reproduction: https://stackblitz.com/edit/github-czi3qh?file=README.md
In the reproduction, there are three chunks entry -> dep1 -> dep2 and augmentChunkHash is used to change dep2 chunk's hash for each build.
What is expected?
On rollup, it affect parent chunk's hash.
$ npm run build-rollup
[debug] [ 'entry-JLv7mwm2.js', 'dep1-BjiIigbx.js', 'dep2-FFxFXinQ.js' ]
$ npm run build-rollup
[debug] [ 'entry-DfZTTeuI.js', 'dep1-dlGUTxta.js', 'dep2-nUWkYB-M.js' ]What is actually happening?
On rolldown, it affects only dep2 chunk.
$ npm run build
[debug] [ 'entry-CBcHEEV8.js', 'dep1-CN1ADQTv.js', 'dep2-CeH93yrm.js' ]
$ npm run build
[debug] [ 'entry-CBcHEEV8.js', 'dep1-CN1ADQTv.js', 'dep2-Bo3o0C0E.js' ]System Info

I'm investigating test failures on rolldown vite https://github.com/vitejs/vite/blob/8773916797f8c0f53f3d7eef0542f1c8ffbb9121/packages/vite/src/node/__tests__/build.spec.ts#L63. I'm not sure if this test was working as intended with rolldown, but since v0.15, it became a clear (but flaky) failure.
Comparing with the tests on original Vite, I found the difference of hash and the behavior of augmentChunkHash in general.
