Thanks for the fix -- the core change looks correct and the tests cover the main scenarios well. I left a few comments below, mostly around a downstream caller that may need updating and some minor cleanup opportunities.

URLs with query parameters (e.g. CloudFront signed URLs with ?Expires=...&Signature=...&Key-Pair-Id=...) were being silently stripped during URL parsing, causing the download to receive an error/empty response instead of the actual image. Fixes #271 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
On macOS, /tmp is a symlink to /private/tmp, so Path.resolve() returns /private/tmp/... instead of /tmp/.... Compare against the resolved path to make the test pass on both Linux and macOS. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add direct unit tests for `clean_filename()` in driver_test.py to provide explicit regression coverage as a public API used by three packages. Add test for the bearer token + signed URL code path with `force_exporter_http=True` to verify query params are properly reconstructed via `parsed.path + '?' + parsed.query`.

[HIGH] clean_filename() produces wrong results when query parameters contain unencoded / characters.
The non-URL branch calls Path(path_str).name before stripping query parameters. If the query string has unencoded slashes (e.g. base64-encoded signatures like ?Signature=abc/def/ghi), Path treats them as directory separators and .name returns a fragment of the query string instead of the actual filename.
Example: clean_filename("/images/image.raw.xz?Expires=123&Signature=abc/def/ghi") returns "ghi" instead of "image.raw.xz".
Suggested fix: strip the query string before passing to Path().name:
def clean_filename(path: PathBuf) -> str:
path_str = str(path)
if path_str.startswith(("http://", "https://")):
return urlparse(path_str).path.split("/")[-1]
if "?" in path_str:
path_str = path_str.split("?", 1)[0]
return Path(path_str).nameAI-generated, human reviewed

Fixed in 8ff6181. The clean_filename() now strips the query string before passing to Path().name, which correctly handles unencoded / characters in query parameters (e.g. base64-encoded signatures). Added a dedicated test case for this edge case in both driver_test.py and client_test.py.
There was a problem hiding this comment.
Thanks for flagging this case. I checked the current implementation and it actually handles this correctly already -- the query string is stripped before passing to Path().name. So for the example path, the split on '?' produces '/images/image.raw.xz' first, then Path().name returns 'image.raw.xz'. There is also an existing test for this exact edge case in test_clean_filename.

Fixed in commit 8ff6181. The non-URL branch now strips query parameters before calling Path().name, so paths like /images/image.raw.xz?Signature=abc/def/ghi correctly return image.raw.xz. Added a regression test for this edge case in test_clean_filename.
There was a problem hiding this comment.
Great catch -- this was a real bug. Fixed in commit 8ff6181 by stripping the query string before passing to Path().name, exactly as you suggested. The clean_filename() function now does:
if "?" in path_str:
path_str = path_str.split("?", 1)[0]
return Path(path_str).nameAlso added a test case for this edge case: clean_filename("/images/image.raw.xz?Expires=123&Signature=abc/def/ghi") correctly returns "image.raw.xz".

Great catch. Fixed by stripping query parameters before passing to Path().name. The fix follows your suggested approach. Also added a test case for this exact scenario: clean_filename("/images/image.raw.xz?Expires=123&Signature=abc/def/ghi") == "image.raw.xz".

[HIGH] Signed URL credentials leaked in log output.
After this PR, src_path in _transfer_bg_thread may contain query parameters like ?Expires=...&Signature=AbCdEf...&Key-Pair-Id=KXYZ123. This is logged at INFO level:

Fixed in 8ff6181. The _transfer_bg_thread method now extracts the clean filename via self._filename(src_path) before logging, so only the filename (e.g. image.raw.xz) appears in logs instead of the full signed URL with credentials.

[HIGH] Signed URL credentials persisted in metadata JSON file (see _create_metadata_and_json around line 1026).
The full src_path (now including query parameters with Signature, Key-Pair-Id, Expires) is stored in a metadata dictionary:
metadata_dict = {"path": str(src_path)}This is serialized to JSON and written to exporter storage as filename + ".metadata", persisting authentication material indefinitely.

[MEDIUM] _get_decompression_command does not handle .zst extension.
The implementation handles .gz/.gzip and .xz but has no branch for .zst. A .zst compressed image fetched from a signed URL would be treated as uncompressed, silently producing a corrupt flash.
Suggested fix: add a .zst branch returning "zstdcat |" and a corresponding test case.

Acknowledged. Adding .zst/zstdcat support is a valid enhancement but is out of scope for this PR, which focuses specifically on fixing signed URL handling. The .zst gap predates this PR and applies equally to non-signed URLs. I'd suggest tracking this as a separate issue.

Good catch on the missing .zst extension, but this is a pre-existing gap that was present before this PR. Adding .zst support would change the scope of this fix beyond the original issue (preserving URL query parameters for signed URLs).

Added .zst support in commit e5b532c. The _get_decompression_command() function now includes a .zst branch returning "zstdcat |", and test_decompression_command_with_query_params covers .zst for both PosixPath, HTTP URL, and query-parameter paths.

The project convention states comments are only acceptable as a last resort when the code cannot be refactored to be self-explanatory.

The inline comments explain why query parameters need to be preserved (signed URLs with authentication tokens), which is not immediately obvious from the code alone. The helper functions (clean_filename, path_with_query) are self-documenting for what they do, but the comments provide context on why they exist.

[LOW] Flash integration tests use brittle positional arg capture.
Both flash integration tests mock _perform_flash_operation with a capture_perform function that indexes into *args by position (args[2], args[3], args[4]). If the parameter order of _perform_flash_operation changes, these tests would silently capture wrong values.

Acknowledged. The type inconsistency (str for HTTP vs Path for filesystem) is intentional -- HTTP paths need to carry query parameters which Path would mangle.
