HAWK exits and McEliece parameters buckle under fresh attacks
An AI-assisted lattice reduction forces HAWK out of the NIST signature round while quasipolynomial results leave Classic McEliece's proposed sizes without defenders.

From blanket bans to AGENTS.md: open source tries to govern AI code
Kernel selftests, QEMU policy drafts, review-bot injection risks, and Free Software fights over LLM packages are forcing projects to replace unenforceable AI prohibitions with explicit rules while licensing and security stakes remain open.
