charset=UTF-8 Content-Transfer-Encoding: 8bit Finding 1: Added `isFileLocalDef` hook to ScopeResolver contract + implementation in free-call-fallback.ts to filter C static functions from global free-call fallback. Threads caller filePath through pickUniqueGlobalCallable so static defs in other files are excluded. Finding 2: Documented single-invocation assumption on staticNames Map. Added clearStaticNames() call in loadResolutionConfig to prevent cross-repo contamination in server-mode scenarios. Finding 3: Added tree-sitter query pattern for function pointer typedef aliases (typedef void (*callback)(int, int)) in query.ts. Added unit test. Finding 4: Added c-static-isolation integration fixture (a.c with static helper, b.c with non-static helper, caller.c) and test asserting no CALLS edge from caller to a.c's static helper.
