## Summary
- make mobile unread state visible with bold channel names, an animated
Inbox badge, and swipe-to-toggle Inbox rows
- add directional transitions for top-level mobile navigation
- let mobile send while media uploads, with cancellable progress UI
- normalize iOS and Android video uploads, attach poster frames, and
improve native video playback
## Validation
- `just mobile-check`
- `just mobile-test`
- `cargo test -p buzz-media`
- Pixel smoke test
- iPhone smoke test
Desktop background uploads moved to #4522 so the two platforms can be
reviewed independently.

**Category:** improvement
**User Impact:** Mobile users can scan Activity as a focused
conversation inbox and open the exact unread message or thread
represented by each item.
## Context
Mobile's Activity tab had not kept pace with Desktop: it presented
isolated event headlines, advertised categories that were often empty,
and opened a channel without clearly landing on the selected item.
This PR brings the Mobile surface toward the conversation-oriented
direction explored in Clay Delk's Desktop [Inbox refactor PR
#2045](https://github.com/block/buzz/pull/2045), while adapting it to
Mobile rather than copying the Desktop split-pane implementation. The
related product/UX discussion is captured in the originating [Buzz
thread](buzz://message?channel=a9bbc0e5-d25d-4740-849c-93c34bb578a4&id=a7d9a4d33dcd8c6bf0dc67d81c328892b9e38dedaa8548920224ef388301b6ab).
## UX decisions in this PR
- **Conversation-oriented, not event-oriented:** related updates
collapse into one row per thread/DM conversation, represented by the
latest update and ordered by latest activity. Separate top-level
conversations in the same channel remain separate rows.
- **Resume at the oldest unread:** tapping a grouped row opens the
represented canonical message/thread/DM at its oldest unread item,
rather than merely opening the channel at an arbitrary position.
- **Desktop-aligned row hierarchy:** rows lead with a full avatar and
sender, followed by contextual location/type metadata, unread dot +
time, and a two-line preview. A **New** boundary separates unread and
read content.
- **Mobile-native navigation:** Mobile keeps a single-column `Activity →
canonical conversation → Back` flow. It does not introduce Desktop's
persistent detail pane.
- **Compact filtering:** the old horizontal chip rail becomes a compact
filter menu so the source set fits a phone viewport without horizontal
scanning. Filters are All, Mentions, Threads, Needs Action, Activity,
Agents, Reminders, and Drafts.
- **Focused source semantics:** All covers personally relevant work—DMs,
mentions, thread replies, needs-action events, owned-agent activity, due
reminders, and active drafts—rather than becoming a generic stream of
every channel message. Mobile's standalone Activity source is currently
limited to DM traffic because it does not have Desktop's aggregated
channel-activity feed.
- **Shared read behavior:** rows project canonical
channel/thread/message markers, support unread-only and mark-all-read,
and use local overrides only where canonical markers cannot represent an
item.
- **Reminders and drafts are real data:** reminders use the same
encrypted NIP-ER events as Desktop. Drafts persist device-local composer
state, restore on return, survive failed sends, and clear after
successful sends.
- **Explain navigation failures:** an unavailable destination produces
an explanatory message rather than silently doing nothing or falling
back to an unrelated channel position.
## Implementation summary
- Adds a Mobile inbox model for conversation grouping, category
priority, contextual labels, sorting, filtering, and oldest-unread
targets.
- Expands relay-backed sources for mentions, approvals, owned-agent
lifecycle events, and DM traffic.
- Adds fail-closed NIP-ER reminder decryption and device-local
compose-draft persistence.
- Redesigns Activity rows, boundaries, filters, unread controls, and
empty/loading states.
- Routes rows through Mobile's existing canonical channel/thread screens
with precise target IDs.
- Adds model, provider, widget, reminder, read-state, draft-lifecycle,
and deep-link coverage.
## Reproduction steps
1. Run Mobile and open **Activity**.
2. Confirm full avatars, sender-first rows, context labels, unread
indicators, timestamps, two-line previews, and the compact filter
control.
3. Open the filter menu and verify All, Mentions, Threads, Needs Action,
Activity, Agents, Reminders, and Drafts.
4. Tap a grouped thread row and confirm the canonical conversation opens
at its oldest unread message.
5. Mark rows read/unread, enable unread-only mode, and use
mark-all-read; confirm state agrees with the channel/thread destination.
6. Type without sending in a channel or thread, leave, and confirm the
draft appears in Activity and restores in the composer.

Recaptured on the same authenticated iPhone 17 simulator, account,
theme, and Activity view, at this PR's current merge-base (`dd222a509`)
and head (`52ad40aee`). Both frames were taken within a few minutes on
the same live feed, so the visible conversation set overlaps closely
(the recent Ned/Bart/Tommy items appear in both). The compared change is
the row *structure*: Before leads with an `@ Mention` headline over a
small inline avatar and a horizontal chip rail; After leads with a full
avatar, a compact `labelMedium` sender label, contextual "Mentioned in"
metadata, and a filter menu. The sender username now renders at the same
compact scale the old `@ Mention` label used.
## Verification
- Current rebased head: `5bd87f4f4` on `origin/main` at `dd222a509`;
GitHub reports the PR mergeable.
- `flutter analyze` — clean at `5bd87f4f4`.
- Full Mobile suite — 698 passed, 1 skipped, 4 failed; all four failures
reproduce identically on clean `origin/main` (`channels_page_test`
create-channel sheet and three `compose_bar_test` agent-mention cases).
- The prior PR-specific `home_page_test` failures were fixed by
providing the Activity local-state dependency in that harness.
- Independent code and simulator UI review — approved.
- Post-rebase GitHub checks are running.
