`lib/graph/` already held the two graphs a compilation carries; it now holds what they are graphs of. The edges join it — `Dependency`, the `DependenciesBlock` holding them and the `AsyncDependenciesBlock` for a block loaded on demand — and so does the chunk side, `Chunk`, `ChunkGroup`, `Entrypoint` and `HotUpdateChunk`. `lib/dependencies/` keeps the concrete subclasses and `lib/template/` the `DependencyTemplate` they print through; these are the base classes every build has. Root goes from 49 files to 45. Three re-exports are owed and kept. `ignore-webpack-plugin` requires `lib/Dependency` at the top level and peers webpack >=5; `external-svg-sprite-loader` and its pixolith fork require `lib/Chunk` the same way; `@vue/preload-webpack-plugin` requires `lib/Entrypoint` at module scope and peers webpack 5. `lib/Chunk`'s and `lib/Entrypoint`'s `tsType` in the schema point at the real path, since a type cannot be read through the re-export. `lib/AsyncDependenciesBlock` is recorded as unreachable instead: its only importer is hard-source-webpack-plugin, which also imports `lib/DependenciesBlockVariable` and `lib/JavascriptGenerator`, both removed in webpack 5. The two serializable classes keep their old request restorable through `registerLegacyRequest`, so a cache pack written before this loads. `AsyncDependenciesBlock`'s removed-property tombstone gains the JSDoc its `Dependency` counterpart already carried — without it the getter infers an implicit `any` that `tsc` reports once the file moves.
`DefinePlugin` replaces a free identifier with a constant at parse time, and `EnvironmentPlugin` and `DotenvPlugin` are each that same plugin fed from somewhere else — one from `process.env`, one from a `.env` file, both constructing a `DefinePlugin` and handing it definitions. The three move together. `ProvidePlugin` substitutes an import rather than a value, so it stays out. Root goes from 45 files to 42. No re-export is owed: the ecosystem scan records no package importing any of the three paths, and none of them is serializable or named by a `tsType`. `DotenvPlugin` reads `schemas/WebpackOptions.json` relative to itself to validate its own options, so that request moves down a level with it.
…n them `ModuleInfoHeaderPlugin` prints the per-module comment header into the generated bundle through `Template`, so it joins `lib/template/`. `LazyBarrel` finds the barrel files worth deferring and is required only by `Compilation`, and `ConcatenationScope` is the protocol scope hoisting runs on — `lib/optimize/ConcatenatedModule.js` is the only thing that constructs one, while generators across `lib/` render through it — so both join `lib/optimize/`. Root goes from 42 files to 39. `lib/errors/` needed nothing: `WebpackError` and `ModuleNotFoundError` were moved there already and the root files are re-exports, as are `InitFragment` and `DependencyTemplate` for `lib/template/`. No re-export is owed for these three — the ecosystem scan records no package importing them — and none is serializable or named by a `tsType`.
…r for The three-way classification the guide describes leaves a path nobody imports in neither map, which reads as an omission rather than as a decision. Record those nine under `removed` with the reason, so the record answers for every path that left `lib/` root in this change rather than only for the ones an importer was found for. The consequence is worth stating: `--write` skips a path `removed` names, so a package that starts importing one of these later is no longer recorded, and `--check` no longer learns a re-export is owed.

`mergeDistantRules` landed with two expectations written before #22201 made an at-keyword read as the name its escapes spell. They assert that `@\6d edia` is left as it stands and that an escaped `@keyframes` keeps `from` — both of which were only true while the tables were keyed by the raw spelling, so they have failed on `main` since #22174 merged. The behaviour is the one #22201 established and is what the plain spelling already gets: the two escaped conditions join, the sheet echoes the spelling back as written, and the keyframe selector shortens. Added alongside is the refusal under an escaped name, since reading the name is what reaches it.

Summary
Continues the
lib/grouping from #22118, #22191 and #22202, in three commits. 13 files move out oflib/root (49 → 39):lib/graph/gains what the graphs are graphs of —Dependency,DependenciesBlock,AsyncDependenciesBlock,Chunk,ChunkGroup,EntrypointandHotUpdateChunk; a newlib/define/takesDefinePluginand the two plugins that are aDefinePluginfed from elsewhere (EnvironmentPlugin,DotenvPlugin); andModuleInfoHeaderPlugin,LazyBarrelandConcatenationScopejointemplate/andoptimize/. Behaviour is unchanged: every file moves as a git rename andtypes.d.tsregenerates byte-identical.Three re-exports are owed and kept, each to a package that peers webpack 5 and requires the path at the top level:
lib/Dependency(ignore-webpack-plugin),lib/Chunk(external-svg-sprite-loader and its pixolith fork) andlib/Entrypoint(@vue/preload-webpack-plugin).lib/AsyncDependenciesBlockis recorded as unreachable instead — its only importer is webpack 4 only.lib/Chunk's andlib/Entrypoint'stsTypein the schema point at the real path, since a type cannot be read through a re-export, and the two serializable classes keep their old request restorable throughregisterLegacyRequest.What kind of change does this PR introduce?
refactor
Did you add tests for your changes?
No new cases —
test/unitCases/deepPathShims.unittest.jsalready asserts every deep path the recorded scan names still resolves, and covers the new re-exports off the same record.Does this PR introduce a breaking change?
No.
compiler.webpack.*and the documented API are unchanged, every deep path the scan found either still resolves or is re-exported, and a pre-move persistent cache pack still restores.If relevant, what needs to be documented once your changes are merged or what have you already documented?
