 ### Fixes
 
+- Go method calls through a struct field (`target.conn.Exec(...)`) no longer bind to unrelated same-named local methods when the field's type is external — `conn *sql.DB` calls were being attributed to a local interface that happened to declare `Exec`, fabricating internal dependencies. Chained field calls now resolve by inferring the field's declared type from the struct definition: in-project types (including unexported ones like chi's `tree *node`) gain correct, validated call edges that never existed before, and external types (standard library, third-party modules) are left unlinked instead of guessed. (#1276)
 - TypeScript/JavaScript method calls through an imported singleton (`import { store } from './store'; store.notify()`) now resolve to the class method instead of the exported constant, so `codegraph callers` sees cross-file callers of the method — previously only same-file calls were attributed and a method used everywhere could look unused. The same declaration-based type inference applies across the languages that share it (Python, Java, Kotlin, Go, and more), and a failed inference keeps the old edge rather than guessing. (#1292)
 - `codegraph node <symbol> -f <file>` now prints the symbol's source body. Pinning an ambiguous name to a specific file (the whole point of `-f` when many files define the same function) returned only the location and caller trail with no code. (#1284)
 - Deleting a whole directory is now picked up by watch mode: the files inside it are removed from the index on the next auto-sync instead of lingering as stale records until an unrelated edit happened to trigger one. Operating systems often report a directory deletion as a single event on the directory itself (with no per-file events for its contents), which the watcher previously discarded. (#1285)
