## Summary
Reduce startup request amplification and let quota-refused background
work recover without changing relay quotas or bypassing the existing
Send gate.
- Coalesce nest regeneration into one worker plus the latest pending
generation. Keep the stale-write fence; bound the archive read so an old
workspace cannot strand newer work.
- Claim pending channel subscriptions before awaiting setup; cancel
removed/unmounted entries and preserve still-owned subscriptions across
reconnect handoff.
- Recheck extended cooldown deadlines before retry dispatch; distinguish
an explicit zero-second hint from a missing hint.
- Recover native finite/unread queries within their original caller
deadline and a three-retry budget, preserving verified unique events,
complete filters and terminal errors.
- Pace renderer initial/live-CLOSED REQs at one per 250ms: visible
channel and explicitly interactive TTS/read-state/observer owners first,
then live-only auxiliaries, then background history. Publication and
finite queries bypass this queue. Reconnect replay now promotes explicit
interactive owners alongside the visible channel with stable
registration-order ties; its existing capped batches and cooldown remain
intact.
**Scope at `867495426`:** 39 source/test files, including 15 production
files (+665/-235) and 24 test/fixture files. The diagnostic recorder,
HTTP instrumentation, trace launcher and raw captures are deliberately
excluded. No profile reset, grouping, quota increase or new global
scheduler.
## Before / after evidence
These are observations from instrumented, human-operated development
Tauri/Vite runs against a production relay, plus explicitly identified
controlled regressions—not a packaged-release startup benchmark.
| Measurement | Before | After | Evidence boundary |
| --- | --- | --- | --- |
| Archive snapshot requests (kind 13535) | 290 | 3 | Recorder-only
baseline → nest-only intermediate candidate; unequal 67.436s / 39.273s
captures and hydration differences |
| Archive responses: HTTP 200 / 429 | 277 / 13 | 3 / 0 | Same
baseline/nest-only captures; not a claim that all quota pressure
disappeared |
| Successful archive responses’ advertised content-length sum |
21,208,505 bytes | 229,695 bytes | Header values, not actual transferred
bytes |
| 154-channel StrictMode replay | 308 REQs | 154 REQs | Controlled real
React hook → real session → mocked Tauri transport regression |
| Add one channel while 154 setups are pending | 309 REQs | 155 REQs |
Same production-boundary regression; ordinary mount remains 154 → 154 |
| Broad renderer request burst / spacing | 110 broad REQs within
10.766ms in pre-drain capture | 250.061ms minimum / 252.131ms median
between broad REQ writes in final longer capture | Different attended
runs; pacing rather than a universal request-rate cap |
| Native unread query outcomes | Baseline: 8 EOSE / 146 quota CLOSED out
of 154 queries | Final longer run: all 156 observed queries reach EOSE;
eight refused queries each recover after two refusals | Different
runs/workloads; query completion, not badge rendering |
### Timing metrics
| Observation | Measured value |
| --- | ---: |
| Baseline’s two accepted chat EVENT socket writes → positive OK |
173.340ms / 85.556ms |
| Nest-only intermediate candidate’s two accepted writes → positive OK |
277.854ms / 78.775ms |
| Final candidate, short run, accepted chat writes → positive OK |
80.636ms / 77.506ms |
| Final candidate, longer run, accepted chat writes → positive OK |
120.712ms / 86.895ms |
| Last initial EOSE among 163 observed broad channel registrations,
longer run | 64.550s after trace start |
| Last EOSE among 156 observed native unread queries, longer run |
73.972s after trace start |
| Native retry waits after 3s then 0s hints, longer run |
3000.7–3002.8ms, then 2001.5–2002.6ms |
| Renderer finite-query retry after a 2s hint, longer run | 2061.365ms |
Both Sends in each final run were accepted, with no recorded negative
OK. Every quota-refused query in the longer run subsequently completed
the same query. Its two Sends happened early (17.878s and 21.655s), not
near the end. These small samples do not support a percentage latency
improvement.
**Tradeoffs and limits**
- 296 background subscriptions imply about 74s of paced registration
before extra cooldowns/high-priority work. The longer capture observed
163 registrations; it did not independently enumerate the expected
membership set or record a queue-empty marker.
- This is not a global 4-REQ/s cap: finite queries, native requests and
reconnect replay are outside the drain and still share relay quota.
Quota refusals recover rather than disappear.
- Socket-write → OK starts after composer submission and any publisher
gate wait. No click-to-visible, launch-to-usable or badge-paint latency
is claimed.
- Native EOSE is not proof of command return, classification, React
state application or visible unread badges. Existing per-channel kinds,
since floors, limits, h-less routing, unread lease/scope guard and
eight-query concurrency remain intact.
- The attended measurements belong to the instrumented candidate, not a
fresh release run of this fixes-only commit. At the initial packaging
checkpoint (`1bf3d060`), eighteen of twenty files were byte-identical;
the other two removed diagnostic gate calls and isolated the nest test’s
temporary paths. The subsequent interactive priority/reconnect and
readiness fixes have controlled hook/session/browser evidence, not
another attended voice/performance run.

## Validation
Current head: `86749542657a60abdfe82eed5cc576d3e162fe5d`, based on
`77729abfb692b25a0f4ec4a69add86af2e32c0dd`.
Review follow-ups:
- `8842dbd8`: explicit interactive TTS admission using the existing
main-window owner, independent of companion/timeline selection.
Real-hook/session/IPC coverage with 296 cold owners proves initial and
CLOSED priority, unchanged filters/cooldown/pacing, background progress
and deduplicated speech.
- `8cb088106`: reconnect preserves interactive priority even with no
visible channel. Stable ordering among foreground ties; real
hook/session reconnect regressions cover cooldown, capped batching, all
297 owners, deduplication and unmount cancellation. Independent reviewer
mutation restored the prior replay implementation, failed both reconnect
rows, then passed the restored candidate.
- `68e76d7c`: read-state and observer reuse interactive priority. Stop
and ModelPicker wait on the existing observer owner inside send
callbacks, after installing result listeners/deadlines. No new owner,
timer or scheduler; inherited CLOSED/fallback/error semantics remain,
rather than a new strict EOSE guarantee. The real Stop panel browser
probe holds observer IPC across the click and checks
observer-before-control order and correlated outcome. ModelPicker
component ordering is source-reviewed only.
- Mock live admission now replays matching stored history with
per-filter time/limit constraints, deduplication, untagged auxiliary
channel fallback and authoritative explicit h-tags. Kind-specific
fixture admission waits and retry-resolving hover actions fix
startup-dependent test setup without weakening event/badge assertions.
- `48e9c0dad` and `867495426`: steady-state scroll-prepend setup
observes live admission, subsequent head dispatch, successful/idle query
completion and initial bottom geometry. Phase-2 genuine-growth and ≤32px
anchor assertions are unchanged. This isolates steady-state prepending:
it **does not fix or certify production early-scroll/head-reset
behavior**.
Current validation:
- Normal push hooks at `867495426`: **6,582/6,582 renderer tests**, zero
failed/skipped/cancelled; lint/static checks, typecheck and differential
file-size gate passed. Native source is unchanged from the earlier
checkpoint; no new native run is claimed for these renderer/test
follow-ups.
- E2E build passed at `48e9c0dad` plus the exact subsequently committed
test-only delta (spec blob `469be2eed868c677ba80b859cc871208000fee60`).
The completed affected-smoke run passed **153/153** across
agent-control, badge, entity links, messaging, profile status and scroll
history; the full scroll file additionally passed twice (**36/36**). No
full CI-smoke pass is claimed from this six-file local run.
- Pinky independently reviewed production and test follow-ups, including
the final scroll spec blob `469be2eed868c677ba80b859cc871208000fee60`,
with no blocking finding. Review is source evidence, not an independent
test run.
- **Not merge-ready:** new-head required CI must complete, exact-range
security review requires authorization, and GitHub currently reports
REVIEW_REQUIRED; fresh exact-head reviewer approval is still needed. No
approval, dismissal or merge performed. No new packaged/native audio,
launch-to-usable or badge-paint observation is claimed.
Initial fixes-only checkpoint validation
(`1bf3d06024d284a63326fdd353baced0842aeb81`):
- Pre-commit formatting hooks passed; worktree clean.
- Renderer package hooks: 6,570 tests passed, zero
failed/skipped/cancelled; lint/static checks, TypeScript and
differential file-size gate passed.
- Native package hook passed: default and mesh-enabled all-target
Clippy, then the complete native workspace test suite. App library:
3,222 passed / 0 failed / 19 ignored; terminal/integration suites
passed. The real nest trigger/stalled-body test passed on macOS.
- Independent whole-change source review: no blocking findings at this
commit; all 20 file hashes matched the committed blobs and
review/validation manifests.
- Regression coverage includes real hook/session cancellation,
StrictMode/membership re-entry, reconnect ownership, extended/zero
cooldowns, burst pacing, auxiliary readiness (including EOSE before IPC
settles), native socket refusal/retry/deadline/cancellation, unread
fetch/classification and real nest trigger/HTTP/file persistence.
- Earlier isolated renderer mutations that started readiness before
enqueue or removed auxiliary priority each failed the real presence
regression; restored controls passed. No native mutation claim.
- Nest fixture uses explicit app-data/nest paths instead of assuming
Windows known-folder APIs obey HOME/APPDATA. Windows runtime execution
is not claimed; CI/build results remain separate.

## Overview
**Category:** fix
**User Impact:** Agent avatars and empty agent-team placeholders now
keep the same intentional squircle silhouette at every size on desktop,
while human avatars remain circular.
**Problem:** Desktop agent avatars used percentage-rounded rectangles,
which made the silhouette vary by surface and required each avatar
implementation to recreate the shape. Empty team placeholders also drew
a regular CSS border inside the clip, leaving straight inset edges that
looked like a cropped square. **Solution:** Reuse one normalized SVG
clip path across desktop artwork. Empty team placeholders use a
separately clipped squircle outline behind the clipped surface, so both
the fill and outline follow the canonical silhouette.
> **Scope correction:** Mobile is deferred from this PR because a real
Flutter capture could not be obtained reliably in the current build
environment. Previously attached mobile images were hand-composed
synthetic layouts, not captures from the running app; they have been
removed and must not be treated as validation. The mobile implementation
is being reverted in one follow-up commit so it can be reapplied and
verified separately.

</details>
## Reproduction steps
1. Run the desktop app and open a channel containing both agent and
human messages.
2. Compare agent avatars in the message list, inbox, huddle
participants, projects, and profile panel. Agent images and fallbacks
should share one smooth squircle silhouette at each size; human avatars
should remain circular.
3. Open **Agents** and inspect an empty agent-team card. Its placeholder
fill and outline should both be smooth squircles, with no straight inset
cropped-square edges.
4. Open an agent profile from a message and confirm the larger profile
avatar keeps the same proportions as the smaller message avatar.
## Testing
- Desktop Biome check passed for the changed empty-team component and
Agents E2E spec.
- Desktop typecheck and differential file-size check passed.
- Full desktop unit suite passed: 6,453 tests.
- Full Agents integration spec passed: 37/37, including the empty-team
outline regression.
- Post-rebase pre-push gates passed at `304b159a2`: desktop checks,
TypeScript typecheck, differential file-size gate, and all 6,453 desktop
unit tests.
- The shadcn-aligned `rounded-squircle` registration passed changed-file
Biome, desktop TypeScript/build, and pre-push desktop checks at
`27e0c12d3`; the full desktop unit suite passed 6,459/6,459.
## Screenshots
Screenshots are temporarily omitted. The previous captures used the
desktop E2E mock bridge and were not evidence from a live running app,
so they were removed.

## Summary
Selecting two people or agents named Scout could replace the first
recipient with the second even though the message still looked right.
This binds each selection to its exact identity: the first keeps
`@Scout`, and a conflicting selection gets `@Scout (<full public key>)`.
Removing one no longer removes or redirects the other.
- Reuse the existing **@ suggestion list**; team selection and automatic
agent addressing reserve and reuse distinct labels too. Typing an
ambiguous name manually shows an instruction to use the picker and
preserves the draft without publishing—in chat, edits and standalone
forums.
- Share literal mention matching across recipient extraction, removal,
display and editing so a shorter name cannot claim another recipient's
longer or qualified label.
- Rebuild authored references when a message is edited, and use the
latest authorized snapshot when reopening or forwarding.
Rendering/editing can recover qualified identities only from the
message's recorded references, not from a key typed into its body.
Unresolvable historical names remain literal rather than guessed
recipients.
- Wrap full-key labels within narrow/zoomed layouts while keeping their
complete accessible label and ordinary mention icons. Edit activation
waits for the action menu's focus cleanup before focusing the editor.
### Related issue
Targets `main`; mention spacing (#7128) is already merged. Split from
#7114. This is independent of the #7124 → #7125 remote-invitation stack
and does not expand agent eligibility or invitation permissions. The
separate Enter-selection suffix issue remains tracked in #7253.
### Testing
The desktop unit suite and focused mock-Chromium checks passed on the
published integration candidate, including pending-paste selection,
edit/forwarding, copy and narrow-layout cases; formatting, types and
frontend builds passed. On `0b3b18c0`, 64 focused trust/paste/selection
unit tests and six mock-Chromium tests passed with zero browser retries,
including actual timeline chip copy → fresh channel paste → send and
mismatched-key rejection; TypeScript, changed-file Biome and an isolated
E2E build passed. The broader browser run had copy failures before the
focused repairs and is not claimed as wholly green. See [live
CI](https://github.com/block/buzz/pull/7133/checks) for current-head
results. No full local `just ci` pass, native/live-relay or
cross-browser validation is claimed.
To try it: select two same-name recipients, remove one, send, then
edit/reopen and forward; only the intended identities should remain.
Type an ambiguous name without choosing a suggestion and check that
sending retains the draft with an error. Inspect full-key labels in a
narrow window at 150% text size, and open Edit and type immediately.


*Earlier mock-browser captures, not current-head runtime proof. No new
before-state capture; screenshots alone do not prove recipient
delivery.*
**Clipboard trust:** generated full-key-qualified mentions now retain
their exact recipient after copy/paste when the full key matches the
clipboard record and community directory/profile state independently
vouches for the base alias, including numeric collision suffixes. A
qualifier alone does not establish trust. Arbitrary historical labels
still cannot always be reconstructed.

## Summary
- Let Markdown tables use the available message width instead of their
maximum-content width, inheriting the renderer's existing
`wrap-anywhere` handling for long tokens and links.
- Top-align header cells as well as body cells. Give cells a `min-w-24`
readability floor so short labels do not collapse into one-letter
columns; retain the existing table-local scrollbar when many columns
genuinely cannot fit.
- Preserve semantic table markup, links, inline code, and surrounding
message layout. Add three browser regressions through the real message
renderer (channel, narrow thread, and many-column overflow).

### Testing
Original production candidate:
`4427f2e6f9ef85a01a267fe9eabd1cf13cacfb78`; base:
`7a9a5233d9d755e715be0c585cf7850e935d28cf`.
- `pnpm -C desktop check` — passed.
- `pnpm -C desktop test` — 6,110 passed, none skipped.
- `pnpm -C desktop typecheck` — passed.
- `BUZZ_PROTECTED_BUILD_OUTPUT=<isolated-production-directory> pnpm -C
desktop build` — passed.
- `pnpm -C desktop build:e2e --outDir <isolated-candidate-directory>` —
passed.
- `just file-size-check` and `git diff --check` — passed.
- Chromium / mock Tauri bridge: all 3 new Playwright tests passed
against the fixed candidate build. Both wrapping tests fail on the
unchanged base build, while the overflow-fallback test passes. Each
browser run used a unique output directory and a non-reused local server
pinned to its build directory.
- At 883px channel message width: table scroll width **1,395 → 883px**.
At 292px thread message width: **1,395 → 292px**. All cells top-aligned;
long tokens/URLs wrap, link destinations and code text remain intact,
short labels stay on one line, and document width remains 1,280px.
- Focused fresh-frame review checked actual before/after screenshots and
the complete diff. It caught one-letter label wrapping in an early
width-only candidate; the final cell-width floor and regression
assertion address that finding.
Limitations: native Tauri/WebKit and relay-backed integration were not
exercised for this CSS-only delta. Repository-wide `just ci` was
attempted but exceeded the local command budget during unrelated Rust
compilation; it is **not** reported green. The full affected TypeScript
package gates above passed on the exact candidate. Production/E2E builds
retain existing chunk-size and mixed static/dynamic import warnings.
Before/after screenshots are posted below using the repository's
screenshot publication script. No merge, production installation, or
runtime restart is requested.
### CI-driven test-only follow-up
Current head: `925d964b6cf31ba704d74baf73769110774b2789`.
Smoke shard 3 exposed an older test in `messaging.spec.ts:457` that
still required three columns of ordinary prose to overflow horizontally
([failure
log](https://github.com/block/buzz/actions/runs/33771325404/job/100702242706)).
This expectation contradicts the intended wrapping change. Updated its
name and assertion to require containment; the separate many-column
local-scroll test is unchanged. No production code or harness settings
changed in this follow-up.
- Affected browser validation: **4/4 passed** (updated existing
prose/narrow table case plus the three new channel/thread/overflow
cases).
- Reused the immutable `4427f2e6` E2E build on a fresh non-reused
server; production source is unchanged at the current head. The
package/build checks above remain evidence for that unchanged production
tree, not a claim of rerunning the full suite at the new SHA.
- Targeted Biome check, file-size gate, and `git diff --check` passed.
- Current-head CI:
https://github.com/block/buzz/actions/runs/33773490446
- Prior unrelated Bestie baseline failure and reproduction:
https://github.com/block/buzz/pull/7279#issuecomment-5528077181
- Security authorization and review must target the **current** head,
not the old screenshot/build SHA. A Block organization member must
comment exactly `@buzz-security-review
925d964b6cf31ba704d74baf73769110774b2789`.

## Summary
- Supersedes #1913 with a KLIPY-hosted URL implementation.
- Adds KLIPY GIF search and trending results to desktop message and
forum composers.
- Keeps selected GIFs hosted by KLIPY; Buzz stores only the external URL
and media metadata (no imeta tag, since relays only accept hash-backed
local `/media/` entries).
- Aligns the Emoji/GIF picker with Buzz's standard segmented control,
theme surfaces, and motion behavior.
## Relay-to-provider boundary
- The relay proxies KLIPY search/share so the `BUZZ_KLIPY_API_KEY` never
reaches the desktop; the key stays server-side behind a redacted `Debug`
impl.
- The dedicated GIF `reqwest` client sets `redirect::Policy::none()`.
Because the API key rides in the request path, following a provider
`3xx` could replay a key-bearing URL to an attacker-chosen host (an
SSRF/key-disclosure primitive). With redirects disabled, a `3xx` returns
as a non-success status that the handlers map to a generic `502`; the
`Location` target is never read or forwarded.
- Admission reuses the established NIP-98, membership, replay, and
per-pubkey rate-limit gates, with an upstream response-size cap and
allowlisting so KLIPY error bodies never cross the relay boundary.
## Accessibility
- Under `prefers-reduced-motion: reduce`, the picker grid renders a
static provider poster (a normalized `jpg` asset) instead of the
animated preview, or a named static placeholder when no poster is
available. It reacts to preference changes while mounted.
`no-preference` keeps the animated preview.
- Selected GIFs carry their title through `ImetaMedia`'s `displayLabel`,
so the composer thumbnail, preview dialog, editor, lightbox, and remove
control all derive one non-empty accessible name instead of an empty
`Attachment ` label. Ordinary hashed uploads keep their existing
hash-derived names.

**Category:** fix
**User Impact:** Editing a channel message now opens in the main
composer, while editing a thread reply stays in the thread composer,
with focus ready for typing.
**Problem:** When a thread was open, Buzz treated its root message as
thread-owned and opened edits in the thread composer. Menu-driven edits
also lacked regression coverage for immediate focus.
**Solution:** Carry the message's semantic root/reply classification
into the edit target, route only actual replies to the thread composer,
and use the menu primitive's selection event for a reliable handoff.
End-to-end tests cover placement and focus for both paths.

4. Edit the reply; confirm its content loads in the thread composer and

## Summary
- Replace the Link previews and Thread layout dropdowns with the shared
segmented control from #5644.
- Pair each setting with a real, inert preview: production Compact/Rich
link cards and a simplified Focus/Split thread diagram.
- Keep scrub previews local to Settings so only a completed selection
updates the saved preference and real app behavior.
- Keep each setting and preview responsive as one grouped unit, with
focused light/dark and narrow/wide coverage.
## Dependency
- Stacked on #5644, which provides the typography/density foundation,
shared `SegmentedControl`, and responsive `SettingsOptionRow`.
- After #5644 merges, this PR should be retargeted/rebased onto `main`.
## Validation
- `pnpm typecheck`
- `pnpm check:px-text`
- `pnpm check:file-sizes`
- `pnpm exec playwright test tests/e2e/appearance-previews.spec.ts
--project=smoke` (3 passed)
- Focused existing Appearance coverage (2 passed)
- Pre-push desktop checks, typecheck, tests, and Tauri checks

## Summary
- Makes Projects repository-aware across browsing, branch and tag
selection, local and remote source management, work items, commits, and
contextual repository actions.
- Refines project details into consistent single-column reading surfaces
with a resizable, section-aware context pod, while keeping project
conversations available in the attached chat panel.
- Adds persistent sidebar project navigation, direct entity links,
repository discussion channels, contributor identity matching, and
consistent loading and activity presentation.
- Keeps branch-specific controls on code-oriented sections while Tasks,
Reviews, and Channels remain repository-scoped, reducing misleading
context and actions.
Replacement for #5981 with an identical final tree flattened into one
signed-off commit because the required DCO check suite remained stalled.

**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.

ordinary link rather than becoming a chip.
4. Select channel and message links and confirm they navigate correctly
in warm and cold-start states.

## Problem
In compact link preview cards with an image, the thumbnail's corners
looked inconsistent — the flush left side and the interior right side
read as different shapes.
## Cause
The `Attachment` shell rounds its corners with a **smooth-corner
(squircle) clip path** via `useSmoothCorners`, not a plain
`border-radius`. In compact image mode the shell has `p-0`, so the
thumbnail sits flush against its left, top, and bottom edges.
That means:
- **Left corners** are carved by the shell's smoothed clip path.
- **Right corners** are drawn by the thumbnail's own plain
`border-radius`.
A circular arc and a smoothed corner of the *same* radius are different
shapes (at 16px the smoothed curve starts 25.6px along the edge instead
of 16px). So the two sides could never match by picking a radius value —
the thumbnail's class has no effect on its left corners at all.
## Fix
Give the thumbnail the same `useSmoothCorners` treatment as the shell,
so both sides share one curve.
- Radius token unchanged: `rounded-2xl` (16px).
- The shell and the shared `Attachment` component are untouched, so no
other `Attachment` consumer changes.
Verified on a rendered card — thumbnail vs shell now agree on all three:
arc radius (16), smoothing (0.6), and curve start (25.6px).
## Hardening
The underlying issue is an invariant that lived nowhere: **a child flush
against a smooth-cornered parent must share its corner treatment.** This
is why the bug was easy to introduce and hard to diagnose.
- Documented the invariant in `smoothCorners.ts`, where anyone reaching
for the hook will see it.
- Added an `expectSmoothCorners()` guard to the existing compact-preview
e2e test. Confirmed it **fails** when the fix is reverted, so it
genuinely bites.
Note: this cannot be a lint rule — "flush" is a runtime layout fact, not
visible in the source.
## Known follow-up (not in this PR)
The composer link preview (`useComposerLinkPreviews.tsx`) has the same
latent issue: a flush thumbnail with a hand-copied `rounded-l-2xl` that
happens to match the shell's current 16px. It is correct today only by
coincidence of two literals agreeing. Left for a separate PR rather than
expanding scope here.
## Screenshots
The same compact card and content before and after the change.
| Before | After |
| --- | --- |
| Original `rounded-xl` (12px) thumbnail: left corners are clipped by
the card’s 16px smooth silhouette while the right corners keep the
thumbnail’s smaller plain radius | `rounded-2xl` (16px) thumbnail with
the same smooth-corner treatment as the card |

**Category:** fix (CI)
**User Impact:** None — test-only change that unblocks `main` and every
open PR.
**Problem:** `main` has been red since #5629 landed on `45f4b91a3`:
`Desktop Smoke E2E (3)` fails `compact link preview image geometry
truncates long titles to one line` on every build (main run 31727837133,
and e.g. #5792, #5790). Two independently-green PRs raced: #5629 added
the test stubbing its preview image at the raw relay origin
(`http://localhost:3000/media/*.png`), while #5627 rewrites sent
snapshot media through the authenticated local media proxy
(`http://127.0.0.1:54321` in the E2E mock bridge). Merged together, the
image request goes to the proxy origin, the stub never matches, and
`naturalWidth` stays `0`.
**Solution:** Point the route stub at the mock proxy origin, matching
the existing `sent link preview media uses the authenticated proxy in
compact and rich cards` test in the same spec.
**Testing:** Reproduced the failure locally on `45f4b91a3`, then with

**User Impact:** Sent link previews now reliably display their thumbnail

**Problem:** Sent preview cards loaded relay-hosted snapshot media

proxy becomes ready.

## Overview
**Category:** fix
**User impact:** Link previews no longer disappear when a message is
sent while preview metadata or media is still settling. Fast Enter,
rapid Enter, and confirmed-draft auto-send now preserve the preview
without duplicate sends or stale tags.
**Problem:** The composer could look ready before its sender-authored
snapshot tag existed. Send paths could then race preview
resolution/upload, while debounced preview state could attach a tag for
a URL that had already been removed. The same timing also caused
confirmed-draft auto-send to be consumed without sending.
**Solution:**
- Debounce preview resolution to avoid card flicker while typing, then
disable every submit path while a supported external preview settles. A
2-second escape cap still permits a bare-link send if resolution stalls.
- Keep submit synchronous: acquire a composer-local lock before
asynchronous send work, read ready tags from the live URL set, and
reject Enter/form submits while a snapshot is pending.
- Retry confirmed-draft auto-submit until preview settling clears, then
submit exactly once.
- Upload thumbnail and favicon independently. A failed upload shows a
toast and degrades to the surviving media (or text-only) rather than
leaving the card spinning.
- Exclude message-edit mode from preview resolution, upload, and Save
gating. Edit-time preview snapshots remain follow-up #5273.
- Canonicalize fragment-bearing URLs for preview lookup/snapshot
identity while preserving the original fragment links in message text.
## Link preview state walkthrough
Captured using PR #5245's actual public Open Graph metadata and artwork.
The deterministic E2E bridge controls only upload timing so the
transient disabled state can be captured reliably.
| State | Expected behavior | Screenshot |
| --- | --- | --- |
| **1. Snapshot upload pending** | The real PR preview is visible, but
Submit remains disabled until its sendable snapshot tag is ready. Click
and Enter cannot send a bare link during the settling window. | 
|
| **2. Snapshot ready** | Once snapshot upload settles and the tag is
ready, the same preview remains and Submit becomes active. | 
|
| **3. Message sent** | The sent event carries the snapshot tag and
renders the PR title, description, and artwork inline instead of
degrading to a bare URL. | 
|
## Regression coverage
- Enter during metadata resolution or snapshot upload cannot send early.
- Paste-and-immediate-Enter sends after settling; rapid Enter submits
exactly once.
- Confirmed-draft auto-send waits for settling and fires exactly once.
- Removed/replaced URLs cannot leak stale snapshot tags or media refs.
- Thumbnail upload failure toasts and sends with the surviving favicon.
- Edit mode does not resolve/upload previews or gate Save.
- Fragment variants share a canonical preview while original fragment
links remain clickable.
- Existing ready-preview, suppression, bare-link fallback, and
multi-preview behavior remains covered.
## Reproduction steps
1. Open a channel and paste a supported external URL into the composer.
2. Press Enter immediately, before preview metadata/media finishes
settling.
3. Before this fix, the event could be sent without its preview snapshot
(or confirmed-draft auto-send could be lost). With this fix, submit
waits behind the disabled state and fires once with the matching
snapshot tag.
4. Remove or replace the URL and press Enter inside the debounce window.
The sent event contains tags only for URLs still present in the
submitted content.
## Validation
All required PR checks are green, including Desktop Core, Desktop Smoke
E2E shards, Desktop E2E Integration shards, macOS build, security

linked site merely by opening a conversation.
**Problem:** Cold-cache link paste could freeze the composer before the
URL painted; recipient-side unfurling leaked visits; invalid or
unresolved preview work could interfere with sending or leave dead cards
behind.
**Solution:** Paint pasted links before starting cold resolver work,
resolve only in the sender's composer, attach only complete validated
snapshots at Send, and render authored snapshots without recipient
fallback fetching.
## Behavior
- **Cold paste stays responsive:** bare and angle-bracket URL paste
paths commit the visible link before resolver work begins.
- **Sender-only fetching:** metadata is resolved while composing;
recipients render only the sender-authored snapshot.
- **Send never waits:** pending, failed, invalid, and unsendable
previews are omitted. They do not block or cancel the message.
- **Terminal misses disappear:** failed, timed-out, or 404 resolver
results remove the composer card while preserving visible link text.
- **Display-text links work:** Markdown links such as `[review the pull
request](…)` produce and send the same snapshots as bare URLs.
- **Compact and Rich presentation:** Compact remains the default; Rich
preserves source description line breaks and paragraphs.
- **Immediate draft-wide dismissal:** clicking × immediately hides all
previews for the draft, suppresses links pasted later, and emits only
`["link-preview", "none"]`. No confirmation detour. Suppression resets
after send or clearing the draft.
- **Zero recipient fallback:** missing, stale, malformed, off-relay,
unsupported, or suppressed snapshots remain ordinary visible links;
recipients never regenerate them.
## Implementation
- Resolve previews from deferred composer URL state so paste can paint
first.
- Upload finished preview media to the active community relay and
snapshot only valid, sendable media references.
- Atomically capture ready snapshots at submit time; never append a late
preview after send.
- Validate snapshot and suppression tags in desktop/native and relay
ingestion, rejecting duplicate or mixed forms.
- Render composer previews as stable 55px attachment cards at desktop
and narrow widths.
- Add deterministic E2E coverage for cold paste,
ready/pending/failed/invalid previews, display-text links, multiline
Rich descriptions, immediate dismissal, later-pasted links, and
suppression reset.
## Validation
Validated head: `9807ba8952f190e76153834abf8ab61dd40be5e2`
- Push hooks passed: `check-push-org`, branch skew, desktop check,
mobile tests, desktop tests, Rust tests, and desktop Tauri checks.
- Focused screenshot E2E at the validated head: 5/5 passed across
Compact/Rich composer and recipient states, 800px/420px geometry,
display-text links, multiline descriptions, and immediate dismissal.
- PR CI was triggered for this exact head and is currently running;
completed checks are green at the time of this update.
- Worktree is clean and both PR head and validated branch resolve to
`9807ba895…`.

## Summary
- target the visible thread branch collapse guide in the messaging smoke
test
- avoid clicking the underlying collapse rail when the guide overlaps it
- retain the existing post-click assertions that verify the two-reply
branch collapses
## Context
`main` CI failed because Playwright repeatedly attempted to click the
lower `thread-collapse-rail` while the matching `thread-collapse-guide`
intercepted pointer events. Both controls dispatch collapse for the same
branch; the guide is the actual topmost user target and is already used
by `thread-unread.spec.ts`.
Failing run: https://github.com/block/buzz/actions/runs/30575425126
## Validation
- focused Playwright smoke test: 1 passed
- pre-push hooks: desktop check passed; 3,835 desktop tests passed
- `git diff --check`
## Review
Princess Donut reviewed the test-only approach and locator determinism
with no blockers. Mongo review is pending.
