调研方向
Start in graphify/extract.py at the syntax-error warning's display-path conversion, then compare it with the adjacent clean-file warning that handles cross-drive paths. Reproduce with the supplied Lua fixture and different Windows drives, using the stated ntpath.relpath check if needed. Done means extraction returns the graph and emits the partial-extraction warning with a usable source path; an open linked pull request already addresses this issue.

描述
Pre-flight checks
- I have checked the Troubleshooting section in the README
What happened?
A source file with recoverable syntax errors can abort extraction when its path and the scan root are on different Windows drives. The syntax-error warning calls os.path.relpath for its display path, and the resulting ValueError escapes instead of returning the extracted graph and warning.
The expected behavior is to return the graph and report the partial-extraction warning with a usable source path. The adjacent warning for a clean file without symbols already handles this drive condition.
Steps to reproduce
Use this Lua input as broken.lua:
local t = {
function f() end
Call graphify.extract.extract([source], root=scan_root) with the included source and scan root on different Windows drives. This report's execution used a controlled macOS probe: the real extraction entry point ran on this fixture, while the source/root relpath conversion used ntpath.relpath with different drives. A same-drive extraction is the control.
The path operation can be checked independently on any platform:
import ntpath
ntpath.relpath("D:/included/broken.lua", "C:/scan-root")
Error output or graph output
Path-sanitized controlled-probe result:
ValueError: path is on mount 'D:', start on mount 'C:'
The exception escapes the syntax-warning display conversion in graphify/extract.py; the extraction call returns no graph and does not emit the intended warning.
Graphify version

Operating System
macOS
Python Version

Installation Method
built from source (git clone)
Additional Environment Details
The source snapshot was tested with local Python dependencies. The cross-drive operation was simulated with Windows path semantics; this is not a native Windows run. No model request is needed. The earlier cache portability path contained the same exception before the warning failed. No written AST cache file was inventoried, and this report makes no cache-file creation claim.
Additional context
This is the syntax-error warning path. #4059 and #4106 address the separate clean-parse, symbol-less warning; their fix is present in the inspected source. This report does not request changes to graph identities, persisted source paths or cache keys.
