The generation stands in for $DSH_HOME/profiles/node_modules/<name> only for names it carries; other names see that directory as an ordinary ancestor. The interception layer is the first ancestor node_modules above the importer's profile directory, so application-owned profiles follow the same rule. Stale .dsh-module-fallback projections are ordinary symlinks: their shape recognition leaves the resolver, the local package names, and the bundle dependency traversal.
The resolver spec gains a table-driven matrix over importer, package kind, ancestor layers, and directory or symlink form, with readable fixture names.
