The root `/` entry **ignores** the conflicting dependencies entirely (jersey, vertx) +2. Each module gets its own entry with `allow` (only the conflicting dependency) and `ignore` (block major version bumps) +3. Other dependencies that use **different property names** per major (e.g., `jaxb-impl-2.version` vs `jaxb-impl-4.version`) only need `update-types: ["version-update:semver-major"]` on the root entry + +**When adding a new module that reuses a version property at a different major:** +1. Add the dependency to the root entry's `ignore` list (fully ignored, not just major) +2. Add a per-directory entry for the new module with `allow` for the specific dependency and `ignore` for `version-update:semver-major` +3.
