**Category:** fix
**User Impact:** Messages send immediately after submission while link
previews finish in the background, with an option to skip delayed
preview preparation.
**Problem:** Waiting for link-preview metadata or snapshot uploads kept
the composer occupied after users pressed Send, while races between
completion, timeout, and cancellation risked inconsistent payloads.
**Solution:** Freeze and promote speculative preview work into a bounded
background send task, clear the composer immediately, and
publish exactly once with prepared previews or gracefully without them
when skipped, failed, or timed out.

<summary>File changes</summary>
**desktop/src/features/communities/useCommunityInit.ts**
Resets pending link-preview preparation when community context changes
so work cannot cross community boundaries.
**desktop/src/features/messages/lib/linkPreviewPreparationStore.ts**
Adds the coordinator-owned preparation state machine, bounded fallback,
Skip behavior, and exactly-once terminal publication handling.
**desktop/src/features/messages/ui/ComposerUploadProgressOverlay.tsx**
Extends floating background progress UI to include link-preview
preparation.
**desktop/src/features/messages/ui/ComposerUploadProgressPill.tsx**
Adds the preparing-link-preview label and Skip action to the progress
pill.
**desktop/src/features/messages/ui/MessageComposer.tsx**
Hands submitted preview work to the background coordinator and clears
the composer immediately.
**desktop/src/features/messages/ui/messageComposerAutoSubmit.test.mjs**
Updates auto-submit unit coverage for coordinator-owned preview
preparation.
**desktop/src/features/messages/ui/messageComposerAutoSubmit.ts**
Allows submit to promote unfinished preview work instead of blocking
composer submission.
**desktop/src/features/messages/ui/useComposerLinkPreviews.tsx**
Starts preview work speculatively and exposes frozen preparation jobs
for adoption by the send flow.
**desktop/src/features/messages/ui/useMentionSendFlow.helpers.ts**
Carries prepared preview tags through the mention and media payload
helpers.
**desktop/src/features/messages/ui/useMentionSendFlow.ts**
Integrates prepared preview tags into final message publication.
**desktop/src/shared/lib/useResolvedLinkPreviews.ts**
Exposes the in-flight metadata promise so promoted work can be adopted
rather than restarted.
**desktop/tests/e2e/messaging.spec.ts**
Covers immediate submit, upload handoff, Skip/completion races, failure
fallback, auto-send, and exactly-once publication.

## Reproduction steps
1. Enter a supported link and press Send while preview metadata or
snapshot upload is still pending.
2. Confirm the composer clears immediately and the floating progress UI
shows **Preparing link preview · Skip**.
3. Let preparation finish and confirm one message is published with its
preview.
4. Repeat and choose **Skip**; confirm one message is published without
waiting for the preview.
5. Simulate preview failure or timeout and confirm the message still
publishes once without preview tags.

## Summary
- send desktop messages immediately while media uploads continue in
background state across channel navigation
- show immediate progress above the composer and keep Jump to latest
above it
- report the real media stages as Preparing, Processing, Converting,
Uploading, and Finishing
- use Buzz's shared spinner during local media work, then switch to the
real percentage when byte transfer begins
- animate phase-label and status-suffix changes without overlap or
layout jumps
- keep cancel, progress fill, message publication, and community-reset
behavior coordinated with the background task
- use raw Tauri IPC for large browser files so renderer-side byte
serialization does not block initial feedback
## Why
Desktop previously blocked sending while attachments uploaded in the
composer. Large videos could also pause the renderer before progress
appeared, and the progress pill said Uploading while native media
processing was still underway. This makes the initial response immediate
and describes the work actually happening.
## Validation
- `cd desktop && pnpm check`
- `cd desktop && pnpm typecheck`
- `cd desktop && pnpm test` (3,931 passed)
- `cd desktop && pnpm exec vite build --mode e2e`
- `cd desktop && pnpm exec playwright test
tests/e2e/file-attachment.spec.ts --project=smoke` (11 passed)
- focused native media tests (80 passed)
- native Clippy with all targets and features
- pre-push native suite (2,107 passed, 14 ignored; 3 diagnostics passed)
Updated phase snapshots are included in the PR comments.
Split from #4512 so the desktop and mobile changes can be reviewed
independently.
