`pkga.FuncX(...)` cross-package calls in Go monorepos were dropping
through the import resolver — `isExternalImport(go)` flagged any
non-`/internal/` import as third-party because the resolver had no idea
what the project's own module path was. Resolution fell back to name
matching with path-proximity scoring, which on a layered codebase picks
one accidental candidate per call site (~<1% recall per #388's
5,303-vs-1 figure).
- `src/resolution/go-module.ts` (new) parses the `module ...` directive
from project-root `go.mod`, exposed via `getGoModule()` on
`ResolutionContext`.
- `isExternalImport(go)` treats `<module-path>/...` imports as in-module;
the existing `/internal/` escape hatch is preserved for repos without
a parsed go.mod.
- `resolveViaImport` gets a Go cross-package branch that strips the
module prefix to a project-relative directory, then resolves the
qualified member via `getNodesByName(member)` filtered to that exact
directory and `isExported=true`. Sub-packages don't collide with their
parents; same-name funcs in different packages don't false-merge.
- Go extractor sets `isExported` from the identifier's first character
(Go's universal uppercase=exported convention). The resolver depends
on this to filter candidates.
Validation on gRPC-Go (1,031 .go files, layered package tree):
total `calls` edges: 23,803 -> 34,105 (+43%)
cross-pkg `calls`: 10,880 -> 19,929 (+83%)
fmt/strconv/etc. stdlib calls: stay external (no false positives)
Tests cover in-module disambiguation with same-name funcs in two
packages, aliased imports, and stdlib calls not being false-resolved to
in-project nodes.
Closes#388.
Addresses Go's tree-sitter parsing where structs and interfaces are wrapped in type_spec nodes rather than appearing as direct node types. Moves struct_type and interface_type detection from direct node type matching to a new resolveTypeAliasKind resolver that examines the inner type field, ensuring proper extraction with field visiting and inheritance detection.
Improves search accuracy by boosting results when multiple query symbols appear in the same file, addressing cases where common names like "run" return too many results. Adds Go method receiver type extraction to qualified names for better searchability (e.g., "scrapeLoop.run"). Optimizes database queries with two-pass approach to handle distinctive vs common symbol names efficiently.
Splits the monolithic tree-sitter.ts (3,358 lines) into modular files:
- 14 language config files under src/extraction/languages/
- 3 standalone extractors (Liquid, Svelte, DFM)
- Shared helpers and types modules to avoid circular imports
Also fixes a bug where Java's extractImport hook incorrectly set
handledRefs: true, preventing unresolved reference creation and
degrading codegraph_explore results for Java codebases.
