The Diary renders nothing on reMarkable OS 3.28 (fixed in quill) #25

Device: reMarkable Paper Pro (reMarkable Ferrari, aarch64)
OS: 3.28
riddle: 0.3.0 (libquill.so dated 2026年07月13日)

Symptom

riddle 0.3.0 installs and launches; oracle connects and replies, but the e-ink
never updates:

quill: EPFramebuffer::swapBuffers unavailable
riddle: the diary is open

Cause

OS 3.28 removed the EPContentType argument from
EPFramebuffer::swapBuffers, so quill's hard-coded symbol no longer resolves.
Details + fix in the quill PR: MaximeRivest/quill#1 .

Fix

Merge the quill dual-signature change and cut a riddle release built against
it, so 3.28 Paper Pros render. Verified on hardware for mono live ink (the
diary's path).

Happy to test release candidates on a 3.28 device.
