This pull request modifies the member-call resolvers and import-edge handling in graphify/extract.py, adding per-language scoping so that resolvers consume only raw calls and receiver-type indices from source files they own rather than across all languages. It introduces new helpers (_hint_import_targets, _file_nids_by_path) and an _IMPORT_STEM_LANGUAGES table to stamp target_file hints on stem-named import edges before id-disambiguation runs, and defines per-resolver suffix constants. The changes also include corresponding CHANGELOG entries and new/updated tests in the mixed-corpus member-call and import-alias-disambiguation suites. Surface area spans import target resolution (Python, Rust, Zig, Elixir, PowerShell, Pascal, Bash), member-call resolution across multiple languages, and their associated tests.

• imports_from edges may name target differently than a bare stem id, mis-stamping target_file — graphify/extract.py · Escalate · medium
  • agreed by 2 of 2 members but NOT verified (no proof, no reproducing execution) — consensus is not a verdict; needs human review
