certifi 2026.6.17 -> 2026.10.23 and python:3.11-slim re-pinned to the 2026-10-22 index, so neither certifi's bundle nor the Debian store in the runtime image trusts emSign ECC Root CA - G3.

What changed
The runtime image stops trusting
emSign ECC Root CA - G3, the root behind the eMudhra intermediate CAs whose private keys were recoverable (Cloudflare advisory, 2026-10-20). Python in the image reaches the web over httpx with certifi's bundle, andca-certificatesserves everything else, so both trust stores move.uv.lock: certifi 2026.6.17 → 2026.10.23. Only certifi moves. The 2026.10.23 bundle no longer carries the root.Dockerfile: the runtime stage re-pinspython:3.11-slimfrome88e9763…tob7a9e5f6…, the index pushed on 2026-10-22. Its Debian 13ca-certificatesis 20250419+deb13u1 (DSA-6572-1), which no longer ships the root. Thenode:22-alpinestage is build-time only and stays as it is.After merge, cloud instances receive this with their next image rollout.
