Pull request overview
This PR extends the advanced_chunks/tags_initial integration fixture to ensure modules reached from a user entry via require() are still treated as part of the $initial execution chain and therefore placed into the $initial-tagged chunk.
Changes:
- Add a new
required.jsmodule andrequire('./required.js')it from the ESM entry to exercise the require-edge behavior. - Update the test assertions to verify
required.jsis present ininitial-deps.jsand absent from the lazy chunk, and ignore the newly emittedrolldown-runtime.jsasset in the file list. - Update the snapshot to reflect
required.jsbeing bundled intoinitial-deps.js(and the runtime helper chunk emission).

| crates/rolldown/tests/rolldown/function/advanced_chunks/tags_initial/_test.mjs | Asserts $initial chunk includes require() targets and excludes them from the lazy chunk; filters out rolldown-runtime.js. |
| crates/rolldown/tests/rolldown/function/advanced_chunks/tags_initial/artifacts.snap | Updates expected bundled outputs to include required.js in initial-deps.js and the emitted runtime chunk. |

## Summary - Extends the `tags_initial` fixture so a module reached from a user entry only via `require()` (`required.js`) is asserted to land in the `$initial`-tagged chunk, alongside the statically imported `shared.js`. - The dynamic-only `lazy-dep.js` is still asserted to stay out. - Pins down the current behavior: `link_stage/mod.rs` filters `Require` out of `meta.dependencies`, but `patch_module_dependencies` re-adds those edges via referenced symbols, so the `$initial` BFS still visits `require()` targets. Without this test, a future cleanup of either side could silently drop `require()` targets from `$initial` chunks. ## Test plan - [x] `cargo test -p rolldown --test integration -- --ignored tags_initial` passes - [x] Snapshot (`artifacts.snap`) reflects `required.js` placed inside `initial-deps.js` 🤖 Generated with [Claude Code](https://claude.com/claude-code)
