Two adjustments after the Android boot investigation
(cf. AGENTS.md section 'PostIt.Android boot crash sur AVD
x86_64 : investigation par couches'):
- Avalonia 12.0.4 -> 12.1.1 in PostIt/Directory.Packages.props.
12.1.x is the current Avalonia 12 stable line; 12.0.4 had a
known WindowingPlatformStub regression on Pixel x86_64 AVDs
(issue AvaloniaUI/Avalonia#18459 family). 12.1.1 does not
actually fix the layer-3 NotSupportedException on this
specific Pixel + Android 16 + x86_64 combination (verified
by rebuild + logcat capture on 2026-08-22), but staying on
12.0.4 forever is wrong, and 12.1.1 is the baseline most
users are on. The Makefile qemu-build already passes
-p:EmbedAssembliesIntoApk=true and -p:RuntimeIdentifier=
android-x64 to work around the Fast Deployment / AOT issues.
- qemu-logcat-boot LOGCAT_BOOT_WAIT 15s -> 30s. The crash
reproduces well under 5s, so the wait value is moot for
diagnosis, but 30s gives a wider margin when the runtime
happens to be slow to JIT (boot tries to draw a frame in
texture-pass scenarios). Override on the command line is
unchanged: 'make qemu-logcat-boot LOGCAT_BOOT_WAIT=N'.
No MAUI change: Microsoft.Maui.Essentials was deliberately
unhooked during a hypothesis check and put back to keep the
contact-flow code path stable. The MAUI removal made no
difference to the crash (verified).
