Summary

Dumbest-user audit of MAUverse with fix schemes and implementations for 1.12.3 (32).

Schemes

• docs/UX_AUDIT_1.12.3.md — convenient / bugs / inconvenient / signing
• docs/ANDROID_SIGNING.md + Directory.Build.signing.props.example

Android fixes

• CanStateChange default true (Loading/Empty states work)
• News respects selected filter; error ≠ “empty category”
• HTML decode in news details; teacher suggestion auto-searches
• Subgroup sheet has “later in profile”; tab renamed Расписание
• Friendlier login labels; certificate DOB not fake 2000-01-01
• Profile/schedule null guards; international guide in Russian

iOS fixes

• Don’t treat Moodle group_id as schedule UID (clears mistaken saved UIDs)
• Native «Справка об обучении» wired; API base URL from Info.plist
• Home quick actions switch tabs (no nested duplicate screens) + Retry
• Teachers hint vs wifi error; ru_RU date chips; softer jargon
• Show unparseable phones; mailto + copy on contacts

Android signing

• Engineering keystore flow documented; optional local Directory.Build.signing.props (gitignored)
• Production Play keystore remains out of repo per CI policy

Test plan

• Android: login → subgroup cancel snackbar; news chip stays after tab switch; news offline message; teacher tap loads card
• iOS: schedule loads after login with group name; Forms → native certificate; Home quick actions switch tabs
• Unit tests green; CI Android/iOS Release green
• Local signed build with example props when SDK available
