Module link 

Link strategies for composing environment views (docs/09-store.md).

Order of preference: hardlink → symlink → copy. (Reflink/CoW is a platform-specific syscall added later; docs/17-cross-platform.md.) On Windows, symlinks may require privilege, so copy is the reliable fallback.

Functions

link_best

Link src to dst using the cheapest mechanism that succeeds. Returns the name of the strategy used.
