Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to A later import can cause an earlier call to a local function with the same name to remain unresolved, producing an incorrect call graph.

- Around line 405-407: Update the binding tracking used by the call-target
resolution around imported_targets so module-level non-import assignments mark
an imported local name as rebound; have the resolver return None for rebound
names instead of the original import target, while preserving direct
explicit-import resolution. Add a regression test covering an aliased import
followed by reassignment and invocation.

In `@diffgraph/structural.py`:
- Around line 292-297: Update the module-scope binding logic around
identifiers(left) so top-level function and class declarations are added to
module_rebindings, alongside assignments and loop targets, removing their names
from imported-target resolution. Preserve nested-scope behavior, and add
regression coverage for both a module-level def and class shadowing an imported
alias.
- Around line 456-459: The module rebinding logic currently overwrites imported
bindings globally, removing edges for calls that occur before the rebind. Update
the handling around module_rebindings and call resolution to retain binding
history by source line and select the binding visible at each call’s line, while
preserving later reassignment behavior. Add a regression test covering an
imported alias called before it is reassigned.

Preserve a local call before a later import.
bindings[None] includes imports from the entire module. It does not indicate that an import is visible at call.line.
For this source, run() returns None instead of resolving to the local run symbol:
def run():
pass
run()
from remote import execute as runKeep binding origin and source order in the history. Resolve a visible local declaration before a later import through the normal local-symbol path. Add this regression case.
