Distinguish call-form require from TypeScript import-equals before resolving
inventory paths. Probe CommonJS files before indexes and honor package main
without requiring an index. Retain selected manifest directory identities and
reuse the path lookup owner for canonical ambiguity.
Validated with source/reader tests and a public CLI fixture controlled by the
pinned Node loader. Windows no-follow reader behavior remains unverified.

Normalize path facts once at the owning filesystem boundary, preserve caller spelling and unavailable inventory members, and retain typed read failures. Record exclusion entry kinds so only proven directories can establish descendant symlink targets; omitted legacy kinds stay unknown.
Reviewed fixes include #1969, #2642, #2759, and #2994.
Validation: 26 reference graph source tests passed; prior artifact checks passed 275 tests with one Windows-only skip. Updated compiled import workflows are included in final validation after regeneration.
