OK my sense is this is a nice starting point and I can revert the whole thing, commit file-by-file as I review. Ugh!

onecodex/models/base.py

    _client: ClassVar[Optional["HTTPClient"]] = None  # noqa: F821
    _resource_path: ClassVar[str]  # Default resource path, subclasses override
-    _allowed_methods: ClassVar[AllowedMethods] = {}
+    _allowed_methods: ClassVar[AllowedMethods] = {}  # type: ignore[invalid-assignment]


This can be fixed with NotRequired in Python 3.10+...

        raise_connectivity_error(file_name)

-    if resp.status_code != 200:
+    if resp.status_code != 200:  # type: ignore[possibly-unbound]


I dislike this about requests...

onecodex/lib/upload.py

        file_obj,
        file_name,
-        fields,
+        fields,  # type: ignore[possibly-unbound]


This feels wrong

boydgreenfield · Jul 18, 2025

onecodex/lib/upload.py

    if file_obj_size:
        allowed_chunk_sizes = [size * 1024**2 for size in range(10, 110, 10)]

+        chunk_size = allowed_chunk_sizes[-1]  # Default to largest chunk size


🤨 probably should use the first

onecodex/lib/auth.py


        # retrieve the CSRF token out of it
-        csrf = re.search('type="hidden" value="([^"]+)"', text).group(1)
+        csrf = re.search('type="hidden" value="([^"]+)"', text).group(1)  # type: ignore[possibly-unbound-attribute]


probably should handle missing match case

These are fine

-        rank: Rank = Rank.Auto,
+        metric: Union[BetaDiversityMetric, str] = BetaDiversityMetric.BrayCurtis,


I don't fully understand this issue but feels wrong

    import skbio

-    for rec in skbio.io.read(file_path, **io_kwargs):
+    for rec in skbio.io.read(file_path, **io_kwargs):  # type: ignore[attr-defined]


again feels wrong but maybe it's a library issue

            proj_date = None

-        if proj_date is None:

This is a ty bug since it should be in scope

boydgreenfield · Jul 18, 2025

onecodex/notebooks/report.py


                self.ref_list[ref_label] = (self.ref_num, text)
-                ipy.meta["references"] = self.ref_list
+                ipy.meta["references"] = self.ref_list  # type: ignore[possibly-unbound]


also seems like a ty bug, we should TODO(check-on-ty-upgrade) or similar for these
