R1: accept best-effort FCM background delivery as a documented limitation.
R7: server FCM sender uses google-auth-library (not hand-rolled RS256).
All three open questions (incl. R2 license) now decided; nothing blocks AW3/AW5.
Phased build spec for an Android client at functional parity with the iOS
client. Produced by a multi-agent workflow: 10 iOS-subsystem explorers + 2
Android-tech researchers -> architect synthesis -> 4-lens adversarial review
-> finalize. Mirrors the iOS SPM package set as Gradle modules; 36 tasks
across waves AW0-AW6 with Owns/Depends/Verify, two de-risking spikes.
R2 (Termux license) independently re-verified and downgraded Critical->Low:
terminal-view/terminal-emulator are Apache-2.0 and on JitPack, not GPL-vendor.
Open questions for the user: R1 (FCM background-delivery acceptance),
R7 (FCM OAuth2 dependency).
