From 6cf21a019963468cb853e5c763ef0097115efa46 Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Thu, 10 Sep 2026 17:30:22 +0200 Subject: refactor(common): delete the sender-key implementation nothing uses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `senderkeys.py` and its 13 tests implemented Signal-style sender keys, and production has never called them: chat is a key per group, per epoch, per device, derived by name. The reasoning that ruled the ratchet out stays where it belongs — in `chatbox.py`, at the top of the module that replaced it — because the argument is the useful part, and it now stands on its own instead of pointing at a file to compare against. Kept code that nothing calls is worse than absent code: it reads as an alternative somebody may reach for, and it has to be maintained past every refactor to stay compiling, which is maintenance spent on a decision already made. The three comments naming `GroupSenderKeyStore` are rewritten to say the thing they were illustrating.
