Description

Stacked on #16126. Move library-support resolution behind the install-layout resolver without changing behavior, allowing metadata-specific edges to remain in rule-generation modules.

Record that a package root reached under a competing virtual implementation does not receive its own link closure.

Exercise library dependencies, private libraries, stubs, redirects, namespaces, virtual implementations, PPX runtime libraries, nested Dune consumers, installed packages, and only-packages masking. Record the current missing-library failures before materializing the closure.

Record that a scoped package layout retains melange_requires metadata without materializing its referenced workspace library.

Signed-off-by: Ali Caglayan <alizter@gmail.com>
Make workspace packages declared with (deps (package ...)) expose the ordinary OCaml library closure required by their installed libraries. Materialize only selected library artifacts and generated metadata, including direct redirects, PPX runtime dependencies, and virtual default implementations.

Do not follow package metadata: external packages have no reliable package dependency graph, while OCaml library metadata provides the closure consumers resolve.

Record that a scoped package dependency omits the intermediate metadata in a deprecated-library redirect chain.

Signed-off-by: Ali Caglayan <alizter@gmail.com>
Compute each workspace root library closure in Melange mode as well as OCaml mode so scoped package layouts satisfy serialized melange_requires edges.

Signed-off-by: Ali Caglayan <alizter@gmail.com>
Record that a support redirect owned by another package omits metadata generated for its deprecated package name.

Signed-off-by: Ali Caglayan <alizter@gmail.com>
Materialize each intermediate deprecated-library redirect needed to reach a selected workspace library without exposing unrelated libraries from the redirects' owning packages.

Signed-off-by: Ali Caglayan <alizter@gmail.com>
Generate the META and dune-package files owned by deprecated package names when their redirects are selected by a scoped workspace library closure.

Signed-off-by: Ali Caglayan <alizter@gmail.com>
Move scoped library-closure resolution behind the install-layout resolver so metadata-specific closure edges can be added without introducing dependencies from dependency evaluation back to rule-generation modules.
