Scanned the three foundational Python documentation tools (Sphinx,
docutils, Pelican) and documented the triage outcome.
Pelican joins the clean-scan honor roll (now 25 projects). Both flagged
findings tested as false positives — utils.py:485 is String.index for
'\n', not list iteration; pelican_import.py:663 ReDoS pattern scales
linearly at N=40 (0.11ms).
Sphinx + docutils have multiple M1 hits in node-tree walks
(Node.findall via parent.index per ancestor). Investigated and
benchmarked: both old and new algorithms are O(D*S) — constant-factor
only, not CWE-407-grade complexity-class change. A real fix would
require maintaining a parent_index cache on Element nodes, a refactor
with cache-invalidation surface area beyond a single-defect patch.
No patches shipped this pass; the work is documented for the next
reviewer.
