Follows [#8657](https://github.com/block/buzz/pull/8657) with the three
optional notes from Carl's
[review](https://github.com/block/buzz/pull/8657#pullrequestreview-5703482477).
- **Lowercase hex only.** `verifySchnorrHex` now rejects uppercase
pubkey, message and sig hex, and `verifiedNostrEventFromJson` rejects an
uppercase sig, as the pure-Dart `bip340` decoder does and NIP-01
requires. (The `nostr` package already lowercases an event's pubkey when
it parses one.) Before this, a key holder could publish a second,
uppercase encoding of the same signature and it would verify.
`_decodeSecretKey` still accepts either case.
- **Bestie record.** `decodeDefaultAgent` now verifies with
`verifiedNostrEventFromJson`, like the other Solo `me_*` records.
- **Rejection tests.** The "other pubkey" row now recomputes the event
id, so it reaches the native Schnorr check instead of failing on the id.
Every row now asserts its `EventValidationReason`, a new row covers an
uppercase sig, and `verifySchnorrHex` is checked with uppercase pubkey,
message and sig.
## Testing
- Making either lowercase pattern accept uppercase again fails the
tests.
- `just mobile-check mobile-test` passed on this change before it moved
onto main. On main, the crypto and Solo/me tests pass.

## Summary
Unify mobile conversations in Messages with All / Solo / Team filters, a
collapsing header, and separate Search, New, and default-agent
shortcuts. Move workspace actions into the community menu and keep
collapsed sections intact across filters.
Align Inbox and list typography, spacing, and muted controls. Preserve
native glass layering through navigation and give every filtered list
enough clearance above the footer. The default-agent shortcut reads the
shared encrypted preference and opens an existing chat immediately. When
unset, it opens Agents; a star action selects the default through a
production signed, self-encrypted preference writer. Save failures
remain visible and retryable.
Android now uses rounded navigation controls and filters, optically
balanced search icons, and expanding New/community menus with leading
Tabler icons matching iOS. Preset avatars retain transparent WebM
animation through an Android WebView renderer, with lifecycle pausing
and poster fallback.
### Related issue
None found in searches for mobile navigation issues and open PRs.
### Testing
- Android follow-up: ARM64 debug build, Dart analysis, and emulator
checks passed for menu placement, selection, icon alignment, search, and
avatar playback/pause/resume. The avatar implementation passed 3,840
Flutter tests and native Android tests before subsequent styling
iterations. Automated tests for the later menu/icon iterations were
skipped at the author’s request; those earlier results do not cover the
final styling changes.
- Mobile formatting/analysis and full test suite (3,838 passed, 23
skipped, plus 4 push-configuration tests); regression journey covers
filtering, collapse retention, and scrolling the last Solo row above the
footer.
- iPhone 18 Pro simulator (Honeycomb): filters, menus, Inbox,
Invite/Back, Switch Community, and default-agent chat/Back exercised.
iOS release build and Pairing Preview install/launch passed during
iteration, preserving the saved profile.
- P1 follow-up: production writer-to-reader widget journey covers
selection, publish failure/retry, and the unset footer opening Agents.
Simulator Agents open/close passes; its saved community has no
selectable agents, so live selection was not verified there.
- Independent agent review completed; its Solo footer-clearance finding
is fixed. The final clearance adjustment is covered by widget tests;
physical-device acceptance of that adjustment and hosted CI remain
pending.
Final Messages layout:
Switcher layering during iteration (before → after):
| Before: filter edge showing through | After: Home hidden behind
switcher |
