Overview

This lockfile update raises Soup Sieve from 2.8.4 to 2.9 while preserving the repository's Python 3.10 floor, supported platforms, package set, and hash-pinned artifacts. CI installs the complete development dependency path across supported Python versions and platforms, and the apparent package-feed change restores the repository's longstanding PyPI source rather than bypassing a documented feed boundary. No publishable Critical, High, or Medium defect remains after reconciliation.

Reviewed the supplied pull-request change set across correctness, security/reliability, architecture, and failure behavior.
No publishable findings remained after source verification for this scope.
