19b41e9c8e fix(desktop): stop rate-limited reconnect backfill from tearing down the authenticated socket (#4990)
## Problem

Users on v0.5.5 report "Can't reach the relay" toggling with brief
"connected" flashes (field reports; also the macOS confirmation in
#4908). #4737 closed the stuck-reconnect gaps; this is the opposite
failure: the client redials fine, but then kills its own healthy socket.

Mechanism (all on `main`):

1. AUTH succeeds → session emits `connected`
(`relayClientSession.ts:583`), then awaits `replayLiveSubscriptions()`.
2. Paged channel backfill issues history REQs
(`relayReconnectReplay.ts`, page limit 500).
3. A `CLOSED rate-limited:` on a **history** REQ arms the rate-limit
gate but still rejects the history promise
(`relayClosedRecovery.ts:38-51`).
4. The rejection escapes `replayLiveSubscriptions()` →
`resetConnection()` tears down the authenticated socket.
5. Reconnect → AUTH OK → replay rate-limited again → loop. Each
iteration re-spends the rate-limit budget, so the loop is
self-sustaining.

## Fix

Contain backfill failures inside the replay. Each subscription's paged
backfill now retries behind the rate-limit gate up to
`PAGE_REPLAY_MAX_ATTEMPTS` (3), then degrades to live-only **for this
connection**. Socket health no longer depends on backfill success.
Nothing is lost: the replay cursor (`lastSeenCreatedAt`) only advances
on delivered events, so the next reconnect replays the same missed
window.

## Red/green proof

- Commit 1 (Pinky): e2e injecting `CLOSED rate-limited:` into the
mid-replay history REQ — **red on main** (expected 1 reconnect dial,
observed 2; connected-flash then teardown).
- Commit 2 (this fix): same test **green unchanged** — one dial, state
stays `connected` through the rate-limit hint plus the next backoff
window.

Why existing coverage missed it: the prior rate-limit e2e pre-armed the
gate *before* replay (replay politely waits), and the CLOSED-injection
test targeted a *live* subscription (which has its own retry path).
Nobody injected back-pressure from the history REQ itself.

## Verification

- `pnpm test`: 4374/4374 pass.
- `playwright test tests/e2e/relay-reconnect.spec.ts`: 14/14 pass,
including the new spec.
- `tsc --noEmit` clean; Biome clean on touched files (pre-existing
warnings on main in `personaCatalogRelay.test.mjs` / `terminal.css`
untouched).

## Not addressed here (follow-ups from the same field reports)

- AUTH terminal latch is too aggressive for relay-internal `error:`
rejections (3 strikes during a relay bad window → stuck until
click/relaunch; #4908).
- Server-side: `relay.drainJitterMs` (#4542) defaults to 0 — enabling it
on the hosted relay removes the deploy thundering herd that triggers
these rate-limit storms.

5ed5925a51 fix(desktop): picking Auto on shared compute no longer blocks Create
Selecting "Auto" for a Buzz shared compute agent left Create/Save greyed
out. The submit gate requires a non-empty model on the raw provider/model
pair (`agentAiConfigurationModeSatisfied`), and the model dropdown wrote
blank for Auto.

Blank was also wrong on its own terms. Blank means *inherit the global
model*, so an agent whose model came out blank ran shared compute against
whatever unrelated model global config named - a Claude id sent to a local
mesh node. And `"auto"` is a trigger token rather than a final choice:
Buzz sets BUZZ_AGENT_PREFER_MESH_FOR_AUTO for this provider, and
buzz-agent rewrites exactly `"auto"` to mesh-llm's virtual `mesh` model
once the catalog advertises it (which mesh-llm does automatically at two
or more models). Any concrete model id defeats that translation, so the
old blank encoding could never reach Mixture-of-Agents.

The rest of the feature already encoded shared-compute Auto as `"auto"`
(provider selection, the global model control); the model dropdown handler
was the one inconsistent path. Ordinary providers keep blank, which is the
generic inheritance encoding everywhere else - existing blanks are not
migrated.

`isRelayMesh` is an optional parameter, defaulting to the selection's own
provider. The dialogs derive the value already and would ideally pass it
for the inherited-provider case, but both files sit at the size ceiling
and may not grow; the parameter is there for whoever splits them.

The existing test enshrined unconditional Auto -> blank. It is now split by
provider, with coverage for the inference fallback and the explicit flag.

ea389a4fb4 fix(mesh): the shared-compute dot moves only when something is happening
The sidebar dot pulsed constantly on a healthy row. Motion was wired to
standing states as well as to events, and "capacity you have not joined"
and "sharing with no agent using it" are both permanently true, so the dot
moved forever and stopped meaning anything.

Motion is now reserved for two facts:

  - activity - work in flight on this node (usage.inflight)
  - progress - a start or stop in flight

Standing states say what they are through tone, tooltip, and the popover's
own prompt, none of which animate. Amber now pulses while a model loads,
where a still dot read as stuck through minutes of work.

Brightness only, on the dot itself. An earlier revision animated a
transparent halo ring scaled to 2x while fading to zero, which is
imperceptible at 8px; the correction scaled the dot, which shifted the
row's optical baseline and read as jitter. Opacity is what Tailwind's
`pulse` animates and what Buzz already uses to mean "working"
(ChannelWorkingBadge, AgentStatusBadge).

Short work is no longer dropped: `inflight` is sampled every few seconds,
so a request that starts and finishes between two polls was never seen at
all. The last sighting is latched briefly - it never invents activity, it
only stops forgetting it immediately.

Both share/stop switches read one derived value, so the row and the popover
cannot disagree about an action while a model loads.

e2796d4a89 fix(desktop): virtualize channel member lists (#4991)
## Summary

- virtualize the unfiltered channel member roster instead of eagerly
mounting every member card
- retain the existing member search/add flow and archived-member
behavior
- cover a 500-member roster, bounded mounted rows, and scrolling to the
final member in E2E

## Cause

The members sidebar rendered every active member card at once. On large
channels this mounted hundreds or thousands of avatars, profile/presence
consumers, menus, and DOM rows, blocking the renderer even though
fetching the roster itself is fast.

## Testing

- `pnpm typecheck`
- `pnpm exec biome check src/features/channels/ui/MembersSidebar.tsx
tests/e2e/channels.spec.ts`
- `pnpm build:e2e`
- `pnpm exec playwright test tests/e2e/channels.spec.ts --grep 'members
sidebar (virtualizes large channel rosters|can invite relay-authorized
agents|can invite and remove managed agents|collapses same-persona
managed agents)'` (4 passed)
- pre-push: `desktop-check`, full `desktop-test` (4,371 passed),
branch-skew

16cc3de6d6 fix(desktop): enforce owner-only access in internal builds (#4053)
## Problem

Managed agents in internal Buzz builds should answer only their owner.
Previously, an agent could keep a broader access setting and respond to
other people, which did not match the access policy for internal builds.

This PR makes owner-only access effective for every managed agent in
internal builds and makes that restriction clear in the Desktop UI. Open
source builds remain configurable.

## Changes

- Enforce owner-only access when any managed agent starts or is deployed
from an internal build.
- Show the agent access control as locked to **Only me** in Desktop,
with an explanation of why it cannot be changed.
- Keep Welcome teammates working under the same rule without triggering
unnecessary restarts.
- Leave open source build behavior unchanged. This changes effective
runtime access without rewriting stored or relay-advertised settings.

The companion [#4064](https://github.com/block/buzz/pull/4064) explains
the restriction in-thread when someone without access mentions an agent.

The enforcement will remain inactive in shipped builds until
[squareup/buzz-releases#74](https://github.com/squareup/buzz-releases/pull/74)
marks internal releases during the build.

4da7264d90 fix(acp): pace observer telemetry at 1/s with per-channel batch envelopes (#4917)
## Problem

Observer telemetry is the noisiest client of the relay: the old pacer
(167ms spacing + 90/min rolling cap) let a busy session bill up to 6
events/second against the owner's message quota, and the rolling cap
silently *dropped* frames once exceeded.

Ruling from the rate-limiting investigation thread (channel
`826fc99b-1472-40e7-a529-6b9db8943b8c`): pace at 1/s, always emit,
minimal PR.

**Review round 1 (Max, Sami)** found the first cut wrong in three ways —
tick burst (all pending frames per tick), startup burst (`interval`
fires at t=0), and per-channel quota arithmetic. All fixed and
mutation-verified in round 1.

**Review round 2 (Sami, Max)** found two more against the round-1 head:
1. **Drain-rate collapse (Sami, blocker):** front-run-only packing meant
a frame held ONE event whenever channels interleaved — measured 275 B/s
vs 63.5 KB/s, so an ordinary 2-channel session fell minutes behind with
zero drops and no warning. Silent unbounded latency.
2. **Coalescer byte-cap bypass (Max):** chunks pending in
`ObserverChunkCoalescer` were unbounded and outside the 4 MiB cap — 500
distinct-`messageId` 50KB chunks retained ~48MB with `pending_bytes ==
0` and zero drops.

**Review round 3 (Max)** found the drop accounting undercounted merged
chunks: a coalescer entry that merged N same-`messageId` chunks counted
as **1** in `dropped_events` when evicted (50 merged 1KB chunks evicted
→ counter read 1, 49 generated events unaccounted). Fixed: accounting is
now denominated in **source (generated) observer events** end to end —
each pending entry tracks how many chunks it absorbed, eviction charges
that count, and the count survives flush into the publish FIFO.

**Review round 4 (Sami, Max)** found three more against the round-3
head:
1. **Coalescer byte undercount (both, independently):** a pending merged
entry retains its first chunk's text **twice** until flush — once inside
the serialized event skeleton and once in the extracted text accumulator
— but was charged only `serialized_len`, so true retention overshot the
4 MiB cap ~2× (measured 8.3 MB). Fixed: `push_pending` charges
`serialized_len(&event) + text.len()`.
2. **Cap regressions asserted the accumulator against itself,** which is
how the undercount hid. All three cap tests now assert on independently
**walked** retained bytes (`serialized_len` per FIFO entry +
`serialized_len + text.len()` per coalescer entry), with a secondary
`accumulator >= walked` sanity check. Reverting the fix makes them fail
at exactly 8,328,386 / 8,328,272 bytes.
3. **FIFO-arm source accounting was implemented but untested (Sami M13;
Max reproduced at `cc9333b7c` with 102/151):** the round-3 regression
only evicted a merged entry while still in the coalescer. New test
forces a merged entry (50×1KB, `source_events=50`) through flush into
the publish FIFO, then evicts it from there — mutating the FIFO eviction
to `dropped += 1` fails with the reviewers' exact numbers (102 vs 151).

**Review round 5 (Sami 9/9/9, Max 9/9/9)** — production judged
merge-safe by both; remaining items are tests only, all landed at
`63d821620`:
1. **The walker instrument was itself unverified (Sami M17–M20; Max
independently confirmed the `return 0` mutant survives):** every cap
test asks `walked_retained_bytes()` only for `<= CAP`, so a blinded
walker passes everything — and paired with a reverted `push_pending` fix
the two mutations cancel, hiding exactly the 8.3 MB overshoot it exists
to detect. New two-sided pin: the walker must SEE the first chunk's text
twice, and must agree with the accumulator EXACTLY while both stores are
non-empty. Kills M17, M18, M19, M20.
2. **Two pre-existing snapshot-clone siblings (Sami D5b/D5c;
byte-identical at merge-base `7334ad1e1` — not this PR's regression, but
the PR made the class visible):** aliasing the inner turns map leaks a
post-save turn into the snapshot; aliasing the inner tombstones map
leaks a post-save terminal that blocks a legitimate post-restore
resurrection. Two isolation tests with in-test controls — all three
inner-map clones in `saveActiveAgentTurnsForCommunity` are now pinned.

## Change

**Harness (`crates/buzz-acp`)**
- **Global pacer: AT MOST ONE relay frame per second**, regardless of
channel count or backlog size. `interval_at(now + 1s)` restores the
no-startup-burst property; `MissedTickBehavior::Skip` is now pinned by a
paused-time test (a stalled tick arm fires one catch-up frame, not one
per missed deadline). At 1 frame/s telemetry spends ≤60/min of the
shared 120/min quota; `OBSERVER_PUBLISH_TICK` documents the tradeoff as
the knob.
- **`ObserverPublishQueue` with gather-packing:** events wait as
byte-accounted events (FIFO). `next_frame()` packs the front event's
channel **gathered queue-wide in FIFO order** — frames never mix
channels, and each channel's events keep their FIFO order, but
cross-channel frame order MAY differ from arrival order. That is what
keeps the drain rate in **bytes per slot** (one ~64KB frame/s) instead
of front-run-length events per slot. **Null-channel events
(`agent_panic`-class) are packing barriers** nothing gathers across, so
causally-global events keep exact order against every channel.
- **One byte cap over BOTH stores:** the event FIFO and the coalescer's
pending chunk buffer count against the 4 MiB budget together; eviction
is oldest-first across both (queue front, then coalescer front —
structural age order) with accounting (warn + counter). A
high-cardinality chunk flood is bounded exactly like a plain event
flood. Coalescer entries are charged their **true** retention
(`serialized_len + text.len()` — the first chunk's text lives in both
the serialized skeleton and the extracted accumulator until flush).
- **Shutdown is not a burst bypass:** paced one-frame-per-tick drain
until empty.

**Desktop**
- `unwrapObserverBatch` expands envelopes on the live relay path and
archive-ingest seam (round 1, unchanged).
- **`activeAgentTurnsStore` watermark re-keyed per (agent, channel)**
with a dedicated null-channel bucket: the per-agent `(timestamp, seq)`
gate would silently skip a delayed channel's frames as stale under
gather-packing's intentional cross-channel reorder. Safe because every
turn-mutating path is channel-scoped by the event's own `channelId`
(endTurn's null-turnId fallback matches `turn.channelId`; resurrectTurn
keys on `event.channelId`), so per-channel serialization preserves each
guard the per-agent gate provided. The tombstone-cap justification is
rewritten for the new keying (worst case for an evicted tombstone is a
ghost badge the prune reaps — bounded cosmetic staleness, not
corruption). Community-switch save/restore deep-clones the nested map.
Other per-agent maps stay agent-keyed: the clock offset is a running
minimum (order-insensitive); turns/tombstones mutate only through
channel-scoped paths.

## Version skew — old desktop + new harness

Gather-packing *intentionally* emits cross-channel-reordered frames. An
**old desktop** (per-agent watermark) against a **new harness** will
silently skip a delayed channel's turn-state events as stale — working
badges on that channel can go stale/missing until its next fresh event.
Transcript and archive are unaffected (the transcript store sorts +
rebuilds on out-of-order arrival; the archive is per-channel by
construction). Ship desktop and harness together; skew degrades badges
only, not data at rest.

## Throughput ceiling — "lossless" is qualified

Sustained lossless rate is what fits in one ~64KB frame per second, now
genuinely in bytes under interleaving:

| event payload | events per frame | sustained ceiling |
|---|---|---|
| 100 B | 250 | 250 ev/s |
| 500 B | 99 | 99 ev/s |
| 2 KB | 30 | 30 ev/s |
| 10 KB | 6 | 6 ev/s |

With C channels producing concurrently, publish slots round-robin
between them: per-channel drain is ~64KB/C per second and the 4 MiB
burst budget (~64s single-channel) shortens accordingly. Beyond budget,
oldest-first drops **with accounting** — visible, designed loss.

**Accounting semantics:** `dropped_events` counts SOURCE (generated)
observer events, not retained entries — evicting a coalesced entry that
merged N chunks charges N. On the published side, a merged entry ships
all N sources' text in ONE event, so the reconciliation invariant is
`ingested == dropped_events + Σ source_events over published events`
(for unmerged events, source_events = 1).

## Verification

At `63d821620d3513505e8766ac691a8002f9d4a96f` (this head; `git rev-parse
HEAD` matched in the same shell as every run), rustc 1.95.0:
- `cargo test -p buzz-acp`: **689 lib + 9 integration, 0 failed** —
regressions: interleaved 2-channel drain packs into ≤4 frames not 200
slots; null-channel barrier; queue-wide gather with within-channel FIFO;
distinct-key 50KB chunk flood bounded by the cap with event-level
accounting (published + dropped == ingested, survivors newest);
paused-time `MissedTickBehavior::Skip` pin (verified to fail under
`Burst`: 3 frames vs 1); merged-key eviction accounts every absorbed
source chunk in BOTH arms — coalescer-side (Max's round-3 probe) and
post-flush FIFO-side (Sami M13 / Max's round-4 probe: fails 102 vs 151
under `+= 1`). All three cap tests assert on independently walked
retained bytes, not the accumulator (verified to fail without the
`+text.len()` fix: 8,328,386 / 8,328,272 vs 4 MiB); the walker itself is
pinned two-sided against the accumulator (all four blinding mutants
M17–M20 verified to fail it, including the walker+fix cancellation
pair).
- `cargo clippy -p buzz-acp --all-targets -- -D warnings` clean, `cargo
fmt --check` clean
- Desktop: `tsc --noEmit` clean; node tests **4366 passed, 0 failed** —
snapshot-clone family fully pinned: watermark aliasing (round 4), turns
aliasing and tombstone aliasing (round 5, pre-existing gaps; each mutant
verified to fail exactly its target test with an in-test control). Prior
rounds: cross-channel reorder processed, cross-channel-delayed
null-turnId `turn_error` evicts only its own channel's turn, null-bucket
replay idempotency, same-channel stale/duplicate still skipped,
watermark survives community-switch save/restore
- All pre-push hooks green at the pushed commit (branch-skew,

a7ea86cdcf fix(desktop): enable the content security policy (#4614)
This change enables a Tauri content security policy that limits
executable content to the packaged application and does not allow inline
scripts.

Relay, media, asset, and Tauri IPC schemes remain available for desktop
compatibility. The policy contains the impact of a future renderer
injection; it does not itself remove an injection bug.

## Testing

- `git diff --check origin/main...codex/security-desktop-csp`
- Rebased onto `origin/main` at `5c98932`
- Full CI pending

eb6a37569d fix(desktop): enable message editing in Inbox (#2198)
### What changed?

Inbox detail now gives the current user's messages the same
ownership-gated Edit action as channel view. Editing reuses the existing
composer and mutation flow, preserves attachment metadata, and refreshes
structural overlays so the edited content appears immediately.

Foreign authors' messages remain non-editable, including grouped Inbox
conversations whose selected event is not the representative item.

| Own Inbox message exposes **Edit message**. | Saving the edit updates
the Inbox detail immediately. |
| --- | --- |
| ![Before: Edit message action in Inbox

| ![After: edited Inbox message
content](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/2198/inbox-edit-after.png)
|

### Why?

Inbox rows did not pass an edit handler into the shared message action
bar, so a user's own messages could be edited from channel view but not
from Inbox detail.

### How is it tested?

Desktop checks, unit tests, and the full local CI gate passed. The
focused Inbox Playwright regression passed 3 consecutive runs and covers
current-user edit/save, foreign and archived-channel denial, and
attachment preservation when a just-sent reply is edited before its
relay echo arrives.

Added tests:

-
[`inbox-edit.spec.ts`](https://github.com/block/buzz/blob/inbox-message-edit-action/desktop/tests/e2e/inbox-edit.spec.ts)
-

005fe54d02 fix(desktop): outline the selected community (#4969)
**Category:** improvement
**User Impact:** Selected communities now use a clear offset outline
without tinting or covering their icon.

**Problem:** The selected community state replaced the icon surface with
an accent fill, obscuring image icons and changing the tile's content
treatment. Hover also changed the fill, text color, shape, and opacity,
making navigation states visually jumpy.

**Solution:** Preserve each community tile's neutral surface and content
while using a primary CSS outline for selection and a lighter outline
for hover. The transparent outline offset leaves the space around image
edges unpainted, and adjusted spacing prevents neighboring outlines from
colliding.

/>


<details>
<summary>File changes</summary>

**desktop/src/features/sidebar/ui/CommunityRail.tsx**
Replaces selected and hover fills with offset outlines, keeps icon
presentation stable across states, and adjusts rail and tooltip spacing
for the new outline geometry.

**desktop/tests/e2e/community-rail.spec.ts**
Covers the shared active/inactive surface, radius, text color, opacity,
and outline behavior, including hover invariants.

</details>

## Reproduction steps

1. Run the desktop app with two or more communities.
2. Give the active community an image icon.
3. Confirm the active icon keeps its original image and receives a 2px
primary outline with a transparent 2px gap.
4. Hover another community and confirm only a lighter outline appears;
its fill, text color, opacity, and corner radius remain unchanged.
5. Switch communities and confirm the outline follows the active
community.

24c7995740 fix(desktop): clamp thread panel to channel surface (#4965)
**Category:** fix
**User Impact:** Expanded thread panels now stay fully visible within
the desktop channel area instead of being cut off.

**Problem:** The resize handler clamped the thread panel against the
full window width, even though the panel renders inside a narrower
channel surface. On a 1720px window, this allowed a 1160px requested
width where only 1111px could render, leaving persisted and visible
geometry out of sync.

**Solution:** Clamp resizing against the measured channel-surface width
so the stored width matches what the layout can render while preserving
the minimum 300px main pane.

<details>
<summary>File changes</summary>

**desktop/src/features/channels/ui/ChannelScreen.tsx**
Passes the measured channel-surface width into the thread-panel sizing
hook.

**desktop/src/shared/hooks/useThreadPanelWidth.ts**
Clamps drag-resize updates against the available channel width instead
of the full viewport.

**desktop/tests/e2e/threadpane-ultrawide.spec.ts**
Adds a 1720px regression proving the requested and rendered panel widths
match, while retaining the ultrawide expansion case.

</details>

### Reproduction steps

1. Open a channel thread in the desktop app at a 1720×900 window size.
2. Drag the thread panel's left resize handle toward the left edge to
expand it as far as possible.
3. Confirm the panel remains fully bounded inside the channel surface
and the main channel pane remains at least 300px wide.
4. Reload the channel and confirm the persisted expanded width renders
without clipping.

### Testing

- `pnpm --dir desktop build:e2e`
- `pnpm --dir desktop exec playwright test
tests/e2e/threadpane-ultrawide.spec.ts` — 2 passed
- Push hooks: `desktop-check` and `desktop-test` passed
- `git diff --check origin/main..HEAD`

cda33978b1 style(messages): increase username contrast (#4948)
**Category:** improvement
**User Impact:** Message usernames are now bolder, making it easier to
distinguish who said what at a glance.

**Problem:** Usernames and surrounding message metadata had too little
visual separation, which made message headers slower to scan.
**Solution:** Increase the shared message-author label from semibold to
bold while preserving its existing size, spacing, and interaction
behavior.

<details>
<summary>File changes</summary>

**desktop/src/features/messages/ui/MessageHeader.tsx**
Raises the shared message-author font weight so standard and system
message usernames gain consistent visual contrast.

</details>

## Reproduction steps

1. Open a channel containing messages from multiple people or agents.
2. Compare each message username with its timestamp and message body.
3. Confirm the username renders in bold while the surrounding typography
and layout remain unchanged.

d42d60d64e fix(desktop): rename generic attachment action from 'Attach image' to 'Attach file' (#2381) (#4304)
Fixes #2381.

## What was broken

The message composer's paperclip accepts generic attachments — images,
videos, PDFs, archives, and any other supported file — but its tooltip
and accessible name still read **"Attach image"**. Sighted users might
reasonably believe the control is image-only, and screen-reader users
get an incomplete description of what the button does.

## The fix

Rename the accessible name and tooltip text on the generic composer
paperclip in `MessageComposerToolbar.tsx`:

- `aria-label` — `"Attach image"` → `"Attach file"`
- `<TooltipContent>` — `"Attach image"` → `"Attach file"`

Plus update the 12 affected Desktop e2e selectors across five spec files
to reference the new accessible name:

- `desktop/tests/e2e/file-attachment.spec.ts` (2 selectors)
- `desktop/tests/e2e/spoiler.spec.ts` (2)
- `desktop/tests/e2e/composer-image-draw.spec.ts` (2)
- `desktop/tests/e2e/image-attachment-gallery.spec.ts` (4)
- `desktop/tests/e2e/video-attachment.spec.ts` (2)

## Scope (per the issue)

The feedback screenshot dialog
(`desktop/src/features/settings/ui/SendFeedbackDialog.tsx`) is
**unchanged** — that dialog itself is image-only, so its "Attach image"
wording is accurate. This PR only touches the generic composer control.

## Test plan

- All **105** unit tests in
`desktop/src/features/messages/ui/*.test.mjs` pass locally.
- Verified no remaining `"Attach image"` string outside the
intentionally preserved feedback dialog:
  ```sh
  grep -rn '"Attach image"' desktop/
  # → only hits in SendFeedbackDialog.tsx
  ```
- The six e2e specs are only exercised in CI; the selector updates are
mechanical and verified by grep to reference the new a11y name.

## Blast radius

- **Files touched**: `MessageComposerToolbar.tsx` (two strings); five
e2e spec files (12 selector updates).
- **User-facing behaviour**: one tooltip + one screen-reader name
change; no functional or visual changes otherwise.
- **No API or state change.**

## Out of scope

- The feedback dialog's "Attach image" wording — kept per the issue's
own "Scope" guidance.
- Any i18n plumbing — Buzz Desktop doesn't currently localize these
strings.

2ea9385015 fix(reactions): support max-length custom emoji (#3833)
**Category:** fix
**User Impact:** Custom emoji with valid 64-character names can now be
used as reactions without errors.

**Problem:** Buzz accepted 64-character custom emoji names during
registration, but rejected them as reactions after the required
surrounding colons made the payload 66 characters. Validation also
differed between desktop, SDK, relay, and storage boundaries.

<img width="554" height="47" alt="image"
src="https://github.com/user-attachments/assets/4013452f-210e-4dd3-9003-f45ff3b28dc8"
/>

**Solution:** Keep the product limit at 64 ASCII characters for custom
emoji names, enforce it consistently when emoji sets are registered, and
allow only valid matching custom reaction payloads up to 66 characters.
Widen the reaction projection to preserve the wrapped payload while
retaining the existing 64-character limit for ordinary reactions.

<details>
<summary>File changes</summary>

**crates/buzz-sdk/src/builders.rs**
Defines the shared custom emoji boundaries and covers accepted
64-character and rejected 65-character shortcodes.

**crates/buzz-relay/src/handlers/ingest.rs**
Validates emoji-set shortcodes and permits 66-character reactions only
when they are valid colon-wrapped custom emoji with a matching tag.

**crates/buzz-db/src/event.rs**
Adds storage regression coverage for maximum-length custom emoji
reactions.

**crates/buzz-db/src/migration.rs**
Verifies the reaction column migration is applied correctly.

**desktop/src/shared/api/customEmoji.ts**
Enforces the existing 64-character shortcode maximum during desktop
normalization and registration/import.

**desktop/src/shared/api/customEmoji.test.mjs**
Covers the desktop shortcode boundary.

**migrations/0027_long_reaction_payloads.sql**
Widens stored reaction payloads to 66 characters for the two required
surrounding colons.

**schema/schema.sql**
Keeps the desired schema aligned with the migration.

</details>

## Reproduction Steps

1. Register or import a custom emoji whose ASCII shortcode is exactly 64
characters.
2. Select that emoji as a reaction to a message.
3. Confirm the reaction publishes, persists, and renders without an
error.
4. Attempt to register a 65-character shortcode and confirm it is
rejected.
5. Publish an ordinary or malformed reaction over 64 characters and
confirm the relay rejects it.

## Verification

- `cargo test -p buzz-sdk`: 243 passed
- `cargo test -p buzz-db`: 94 passed, 152 Postgres-required tests
ignored
- `pnpm test` in `desktop`: 3,859 passed
- `cargo test -p buzz-relay`: 795 passed, 9 existing
Postgres-unavailable failures, 35 ignored; new reaction boundary tests
pass directly
- `cargo fmt --all -- --check`
- `git diff --check`

719f9730d4 feat(desktop): allow leaving your final community (#3621)
**Category:** improvement
**User Impact:** People can leave their final Buzz community and return
to **Join or create a community** without losing their signed-in
identity.

**Problem:** Buzz Desktop blocked people from leaving when only one
community remained. Its existing remove action also changed local
configuration without ending relay membership.

**Solution:** Allow the final community to be left. Buzz now asks the
relay to end membership, removes the community locally only after
acceptance, and returns the person to the community selector while
keeping their identity signed in. If other communities remain, Buzz
switches to one of them. Relay rejection or timeout keeps the community
in place and shows an actionable retry error.

<details>
<summary>File changes</summary>

**desktop/src/features/communities/leaveCommunity.ts**
Adds signed kind 28936 publishing for active and inactive community
relays with actionable timeout handling.

**desktop/src/features/communities/leaveCommunity.test.mjs**
Covers event shape, relay selection, acceptance gating, rejection,
timeout messaging, and cleanup.

**desktop/src/features/communities/useCommunities.tsx**
Allows final-community removal and clears community-specific storage
without touching identity.

**desktop/src/features/communities/resolveCommunityRemoval.test.mjs**
Covers final, active, and inactive community removal state transitions.

**desktop/src/app/useCommunityNavigationTransitions.ts**
Gates local removal on relay acceptance and routes to a fallback

**desktop/src/app/AppShell.tsx**

**desktop/src/features/communities/ui/EditCommunityDialog.tsx**
Replaces the local-only remove action with a pending-aware Leave
Community action that retains actionable errors.

**desktop/src/features/communities/ui/CommunitySwitcher.tsx**
Enables leaving the final community and carries the asynchronous
callback.

**desktop/src/features/sidebar/ui/AppSidebar.tsx**
Carries the asynchronous leave callback through sidebar props.

**desktop/src/features/sidebar/ui/CommunityRail.tsx**
Enables leaving the final community from rail settings.

**desktop/src/features/sidebar/ui/SidebarProfileCard.tsx**
Carries the asynchronous leave callback through profile community

**desktop/src/testing/e2eBridge.ts**
Teaches the mock relay to accept NIP-43 leave events.

**desktop/tests/e2e/community-rail.spec.ts**
Updates leave interactions and verifies final-community setup
navigation, storage cleanup, and identity preservation.

</details>

### Reproduction steps

1. Run Buzz Desktop with a signed-in identity and one joined community.
2. Open Community settings and choose **Leave Community**.
3. Confirm the app shows **Join or create a community** and the existing
identity remains signed in.
4. Repeat with two communities and confirm leaving the active one
switches cleanly to the remaining community.
5. Reject or withhold the relay `OK` response and confirm the community
remains configured with an actionable error in the dialog.

### Test plan

- `pnpm check`
- `pnpm build`
- `pnpm test` (3,913 passing)
- `pnpm build:e2e && pnpm exec playwright test
tests/e2e/community-rail.spec.ts --grep "final community"`

7334ad1e16 fix(desktop): route macos notification clicks (#4799)
## Summary
- deliver macOS notifications through `UNUserNotificationCenter`
- route notification clicks to the referenced channel or thread through
the existing frontend activation path
- preserve click targets across cold startup and frontend remounts with
a small process-wide activation queue
- keep Linux notification activation behavior unchanged

## Architecture
A single `UNUserNotificationCenterDelegate` is installed during Tauri
setup. Each notification stores its navigation target in `userInfo`. On
click, Rust queues the target before emitting a wake-up event; the
frontend atomically drains the queue and dispatches the existing
notification action. The queue is the source of truth, which prevents
cold-start loss and duplicate delivery.

## Validation
Verified at `a81241611d617becf7640bee6fe56b5cdb4d0fab`:
- Biome format/check and lint
- TypeScript typecheck
- repository and desktop-Tauri `cargo fmt --check`
- repository and desktop-Tauri Clippy with `-D warnings`
- full pre-push desktop tests and Tauri workspace checks/tests
- desktop production build

Manual macOS validation passed: after explicitly ad-hoc signing the
local bundle with `xyz.block.buzz.app`, the operator confirmed real
Notification Center delivery and click navigation.

<details>
<summary>Local macOS test procedure</summary>

Tauri's generated ad-hoc signing identifier is not accepted by
`UNUserNotificationCenter`. Re-sign the local bundle with its bundle
identifier and keep other Buzz copies closed:

```bash
just desktop-release-build
APP="$HOME/.cache/cargo-target/aarch64-apple-darwin/release/bundle/macos/Buzz.app"
codesign --force --deep --sign - \
  --identifier xyz.block.buzz.app \
  --entitlements desktop/src-tauri/Entitlements.plist \
  "$APP"
codesign --verify --deep --strict --verbose=2 "$APP"
pkill -x buzz-desktop || true
open -n "$APP"
```

43cced308d feat(desktop): sync themes per community (#3653)
**Category:** new-feature
**User Impact:** Users can keep a distinct Appearance scheme for each
community and restore it on another desktop signed in with the same
identity.

**Problem:** A single global theme makes it harder to distinguish among
communities, and local-only preferences do not follow a user to another
device. **Solution:** Save each community's stable theme, accent, and
system-following selection as private encrypted relay state, backed by a
responsive local cache and guarded against switch races, invalid future
records, and relay failures.

### Reproduction steps

1. Join at least two communities and open **Settings → Appearance**.
2. Choose a different theme, accent, or system-following mode in each
community.
3. Switch between the communities and verify each one restores its own
scheme without overwriting the other.
4. Sign in on another desktop with the same Nostr identity, join the
same community, and verify its saved scheme is restored from that
community's relay.
5. Disconnect the relay, change Appearance, and verify the UI remains
responsive and the local fallback is retained.

6c40ce394f feat(desktop): cap OpenClaw agent parallelism at 5 (#4019)
OpenClaw connects to a single shared Gateway daemon. Spawning the
default 10 ACP workers per agent is both resource-expensive and
architecturally wrong — each worker opens a separate gateway connection.
Tyler's ruling: cap at 5, lower if needed.

## Contract

Store the requested value (1–32) verbatim at every persistence and wire
boundary. Apply `effective = min(requested, harness_cap)` only at the
four enforcement points:

| Boundary | Implementation |
|---|---|
| Local spawn | `BUZZ_ACP_AGENTS` env var in child `Command` |
| Remote deploy | `launch.policy_env["BUZZ_ACP_AGENTS"]` + legacy
`parallelism` field |
| Restart badge | `SpawnConfigSnapshot.parallelism` stores effective
value; the diff surface displays what actually runs |
| UI copy | Amber hint when requested > cap; no `max` attribute, no
save-path clamp |

`BUZZ_ACP_AGENTS` is added to `RESERVED_ENV_KEYS` — the Desktop resolves
the effective value into `policy_env`; a user-supplied override in `env`
would bypass the cap and is silently stripped.

## Changes

**`managed_agents/parallelism.rs`** (new) — policy core:
- `OPENCLAW_MAX_PARALLELISM = 5`
- `harness_max_parallelism(command)` — keyed on
`normalize_command_identity` so path prefixes, `.exe` suffixes, and
other cosmetic differences are ignored
- `effective_parallelism(command, value)` — identity for uncapped
harnesses
- `acp_agents_value(command, parallelism)` — `env("BUZZ_ACP_AGENTS", …)`
helper

**`runtime.rs`** — spawn clamp: `BUZZ_ACP_AGENTS =
acp_agents_value(effective_command, record.parallelism)`

**`agents_deploy.rs`** — deploy egress clamp: `build_deploy_payload`
resolves `effective_parallelism` once from `descriptor.command`; both
`launch.policy_env["BUZZ_ACP_AGENTS"]` and the legacy top-level
`parallelism` field use that value — the two are always consistent
regardless of stale `record.agent_command` pins

**`spawn_snapshot.rs`** — `from_inputs` stores
`effective_parallelism(&descriptor.command, record.parallelism)` in the
`parallelism` field. Over-cap edits that don't change the pool (e.g. 10
→ 8, both clamp to 5 on OpenClaw) produce equal snapshots; cap crossings
(8 → 3) produce different snapshots.

**`AcpRuntimeCatalogEntry.max_parallelism: Option<u32>`** — derived from
the static definition command, not the probed `entry.command` (which may
be `null` for unavailable entries), so unavailable OpenClaw entries
still carry the cap. Propagated through all four catalog constructors
(builtin discovery, preset catalog construction, custom discovery,
custom-save response), IPC types
(`RawAcpRuntimeCatalogEntry.max_parallelism`), and the frontend catalog
type.

**UI** — `EditAgentAdvancedFields` and `PersonaAdvancedFields` show an
amber hint when `selectedRuntime.maxParallelism` is set and the current
value exceeds it. Cap and label come from the catalog entry — no
hardcoded 5 in TS. No `max` attribute on inputs; the input stays
`type="text"` with 1–32 copy.

**Docs** — `docs/remote-agents.md`: `BUZZ_ACP_AGENTS` moved from the
deliberately-non-reserved section to reserved; new contract documented.
`desktop/src/features/agents/AGENTS.md`: command-keyed execution policy
documented as the sanctioned second metadata source feeding the catalog
projection.

## Tests

**Rust** (`parallelism.rs`):
- `policy_table` — `harness_max_parallelism` and `effective_parallelism`
across all openclaw variants and uncapped harnesses
- `acp_agents_value_openclaw_above_cap_is_capped` — spawn-env seam
- `override_direction_*` — both override directions (openclaw runtime +
goose override; goose runtime + openclaw override)
- `summary_persona_inherited_*` — live persona wins over stale
`agent_command`
- `snapshot_export_carries_requested_definition_parallelism` — requested
value travels wire/sync unchanged

**Rust** (`spawn_snapshot/tests.rs`):
- `openclaw_above_cap_parallelism_snapshots_equal` — stored 10 vs 8,
both clamp to 5 → snapshots equal
- `openclaw_cap_crossing_parallelism_snapshots_differ` — 8 (clamps to 5)
vs 3 → snapshots differ

**Rust** (`discovery/presets.rs`):
- `openclaw_preset_unavailable_carries_max_parallelism` /
`openclaw_preset_available_carries_max_parallelism` — catalog metadata
present with `command: null` and with a resolved path

**Rust** (`agents_deploy.rs`):
- `launch_block_openclaw_over_cap_policy_env_is_capped` — direct
`launch.policy_env` seam
-
`deploy_payload_json_stale_goose_record_live_openclaw_descriptor_both_capped`
— stale `record.agent_command=goose`, live descriptor=openclaw: both
fields cap to 5
-
`deploy_payload_json_stale_openclaw_record_live_goose_descriptor_both_uncapped`
— stale `record.agent_command=openclaw`, live descriptor=goose: both
fields pass through requested
- `deploy_payload_json_explicit_openclaw_override_both_capped` —
explicit `agent_command_override=openclaw`: both fields cap to 5

**Rust** (`persona_events/stale_pin_tests.rs`):
- `apply_persona_snapshot_goose_to_custom_harness_drops_stale_goose_pin`
— custom-direction stale-pin drop (builtin pin → loaded custom harness
via `update_loaded_harness_registry`)

**TypeScript** (`agentParallelism.test.mjs`):
- `parallelismCapHint` — at/below cap (null), above cap (hint includes
label and cap value), singular form for cap=1, uncapped harness (null)

**TypeScript** (`tauri.test.mjs`):
- `fromRawAcpRuntimeCatalogEntry` round-trips `max_parallelism` →
`maxParallelism`; absent when `undefined`

stale agent suggestions cannot leak back in
- preserve managed-agent behavior and explicitly reject stale
agent-marked channel members absent from both live directories

## Validation

- `pnpm --dir desktop test` — 4,288 passed
- `pnpm --dir desktop typecheck`
- `pnpm --dir desktop check`
- `pnpm --dir desktop build:e2e`
- focused Playwright mention matrix — 12 passed
- focused Playwright member-invitation matrix — 2 passed
- pre-push hooks after rebase to current `origin/main` — desktop check
and 4,288 tests passed

Idempotent self-target behavior remains available, while ordinary
members can no longer extend private-channel access to another identity.

ddce5e6694 feat(mesh): experimental tier for models served across machines
Advanced settings gains a nested Experimental section listing split-capable
models that exceed this machine, with the consequence stated before any choice:
sharing will not start until enough well-connected computers are sharing the
same model. It waits instead of loading, and that waiting is indistinguishable
from a slow download to anyone who was not told.

## Why "beyond this machine" is the partition, not "multi-machine"

The catalog's runtime field marks a model multi-machine whenever a layer package
exists, which is not the same as needing several computers -- Qwen3-8B-Q4_K_M is
5 GB and split-capable. mesh-llm agrees about precedence:
evaluate_model_target_capacity returns SingleNodeFit first and only falls back
to SplitCandidate when no single node can hold the model. So the tier is the
intersection: split-capable AND beyond local memory. Anything that fits belongs
in the ordinary picker, where it starts immediately.

## Catalog comes from mesh-llm's loader

remote_catalog is public in mesh-llm-host-runtime, so Buzz calls it rather than
fetching and parsing the dataset itself -- one implementation of the format.
Hand-parsing is a trap: the package discriminator is `type` on the wire and
`package_type` in Rust via serde rename, and reading the Rust name off the wire
produced a confident "zero models are split-capable" earlier in this work. A
test pins the wire spelling, and it turned out stronger than intended -- serde
rejects a wrong discriminator outright, so format drift surfaces as a parse
error rather than a silently empty tier.

Reads the on-disk cache first and downloads only when nothing is cached, in
spawn_blocking. No running node required: you choose what to share before you
start sharing it.

## Empty is four distinct sentences

Still loading, could not read the catalog, the catalog holds no packages, and
this machine is large enough that nothing needs splitting. The last is good news
and must not read as a failure. A test asserts all four differ.

Two upstream entries publish "30 layers" where bytes belong, which parses to
nothing -- and is why mesh-llm reports unknown_model_size for the model this
machine serves. Unknown size is never claimed to fit: offering the split path is
recoverable, promising a local start that then fails is not.

Also updates the Share compute description to say why it is worth doing rather
than restating the mechanism.

57197bb906 fix(mesh): restore the status dot, and settle on one name
Two regressions from the previous commit.

The dot is the row's reason to exist -- hollow when nothing is known, slate when
there is capacity to join, green sharing, blue consuming -- and the last change
swapped it for a Share2 glyph in the cold state. That threw the signal away in
the one state that still had something to say, and made the row read as a
network widget rather than a status line. The dot is now unconditional in every
state, and Share2 sits beside the invitation it labels.

The same change also invented two names, "MeshLLM" cold and "Buzz MeshLLM"
otherwise, then failed to apply the second to the popover -- so the card kept
saying "Buzz MeshLLM" after the row had dropped it. There is now one constant,
"MeshLLM" (the "Buzz" qualifier adds nothing inside Buzz), and a test asserts
the label is identical across every state so it cannot drift again.

390f0aa6ce feat(mesh): make the cold state name its action
With nothing shared anywhere, the row and popover were both status surfaces
with no status: a hollow dot beside "Buzz MeshLLM", and a "Mesh capacity"
heading over "0 sharing in this community". Nothing said what the switch does,
which is the one thing a first-time reader needs and the one thing a zero
cannot tell them.

The row now drops the "Buzz" qualifier -- "Buzz MeshLLM" plus an invitation
does not fit 256px, and the name is the part that can afford a word -- carries a
Share2 glyph where the status dot would go, and offers "Share your compute" in
the trailing slot. The dot returns the moment there is a real state to report,
which is the more honest signal there.

The popover's cold subtitle explains rather than reports: "Share your spare
compute with the Buzz community to run models." Its heading names the thing
instead of heading an absent number.

Only the cold state invites. A permanent nudge beside a real figure becomes
furniture, and a prompt derived from an unfetched snapshot would appear for one
poll and retract, reading as a glitch.

Also renames the popover's footer link from "Compute settings" to "Advanced
settings": it named the destination, where the useful thing to name is what is
there. The picker, custom model refs, and the memory cap are all advanced
concerns; the popover already covers the everyday ones.

cb1323a2d3 feat(mesh): name the row Buzz MeshLLM, and offer the action when the mesh is empty
An empty mesh was the one state with nothing to show and nothing happening, so
the row sat inert with nothing explaining why. The action is real -- you can be
the first to share -- so the badge slot now carries the word "Share" where a
figure would otherwise go.

Static rather than throbbing. A community that never uses the mesh would
animate forever, and permanent motion earns nothing but annoyance; the invite
throb stays reserved for capacity that actually exists.

An unfetched snapshot still offers nothing at all. A prompt derived from no data
would appear for one poll and retract, which reads as a glitch rather than a
suggestion -- so "not asked yet" and "asked, nothing there" are now separate
branches instead of one condition.

Row label is "Buzz MeshLLM" rather than "Community mesh".

d6dd453ae2 feat(mesh): capacity in the row, and throb when sharing has no consumer
Three changes to the sidebar row, all aimed at making it argue for itself.

The share Switch is gone from the row. It was scaled to 70%, unlabelled, and
sat where SidebarMenuBadge normally puts a number -- hard to see and ambiguous
about what it would do. The popover already had the same control with room to
label it, so the row now carries state and capacity only, and every control
lives in one place.

That frees the trailing slot for capacity in every state that has a number,
not just while sharing. When this machine is outside the mesh the figure *is*
the invitation: "92 GB" argues for joining better than any exhortation, and
unlike a nudge there is nothing to dismiss. Unknown capacity degrades to a
device count rather than printing 0 GB -- a count still says there is something
here.

Sharing with no agent set up to use the mesh now throbs. It deliberately does
not get a colour of its own: blue already means *consuming*, i.e. taking from
the mesh, and sharing-with-no-consumer is the opposite, so reusing blue would
make blue meaningless. The dot keeps stating what is true -- green, we really
are sharing -- while the existing invite throb says there is a step left, and
the tooltip names which. A loading agent list is treated as "assume set up",
so a slow query never flashes a nudge and retracts it.

d23e3cf237 fix(mesh): state what is shared plainly, and scope the memory meter
Drops two captions that hedged or mislabeled facts we have.

"Join to see live detail" was wrong twice over: in that state the only thing to
join is sharing, and the field already shows what the community has published.
"Last reported by the community" annotated a real fact with doubt -- the notes
are current within 120s, and what we know is shared should be shown as shared.
The live-vs-relay difference is already carried by the geometry: relay nodes get
no synthetic RTT, and the centre is hollow with no spokes because adjacency is
what we cannot assert. A caption repeating that was noise.

The only surviving caption states something the drawing cannot: alone on the
mesh.

The memory meter is per-node and now says so -- "This computer · model uses 10
GB of 40 GB". It sits directly beneath a radar field showing the whole
community, so an unqualified figure read as mesh-wide utilization: a number
nobody has, since members publish their own capacity but nothing about each
other's live allocation. A test pins the scoping rather than the wording.

2a2977795a feat(mesh): throb the row when there is compute to tap into
Shared compute in the community is worth noticing even when this machine is
neither using nor adding to it -- that is the moment to either tap in or
contribute, and a static slate dot said nothing.

Pulse is now a named signal rather than a boolean, because two different facts
want motion and a single flag would make a throb ambiguous:

  - activity -- real work is in flight on this node right now
  - invite   -- there is compute here, and we are outside it

They are deliberately unalike. Activity uses Tailwind's stock ping: quick and
insistent, because something is happening. Invite breathes on a new 2.8s
keyframe in slate and never reaches full opacity: noticeable on a second
glance, never competing with unread badges.

An empty or unfetched community still never throbs -- an invitation to join a
mesh that does not exist would be a lie told with animation.

3376dbc665 fix(mesh): show the community mesh before joining it
The popover said "Turn on sharing to see who's on the mesh." That was not just
awkward copy, it was false: mesh_snapshot reads other members' relay status
notes and needs no local runtime, so who is sharing -- and how much -- is
knowable while our own node is off. The graph was gated on a local runtime for
no reason.

The radar field now renders from whichever source this machine has, and keeps
the two honestly distinct:

  - live gossip: reachable now, RTT known, adjacency to us is real
  - relay notes: last known within 120s, no RTT, adjacency unknown

So relay nodes get no synthetic RTT (they land mid-band rather than faking
proximity), spokes are omitted when we have not joined because a spoke asserts
a connection we do not have, the centre is drawn hollow for the same reason,
and a caption names which view is on screen. The replacement copy only appears
when the community genuinely has nothing, and names the actual next step.

Row label is now "Community mesh" rather than "Compute".

36548e0bc3 feat(mesh): one-line Compute row with radar-field detail popover
Sidebar front-page space is premium, so shared compute is now a single menu
line under Agents instead of a ~120px footer card. The row carries one signal
-- a coloured dot -- and everything else moved into the popover it opens.

The dot distinguishes six states, and the pair that matters most is "nothing
here" vs "there is capacity you have not joined": mesh_snapshot reads other
members' relay status notes with no local runtime, so idle capacity is knowable
without starting a node or running a probe. Grey would have conflated the two,
and the second is the reason to look at the row at all.

The switch shows only while not sharing; once sharing, the state is legible
from the dot and Stop lives in the popover, which frees the trailing slot for
live pool capacity. It is never disabled while consuming -- a client runtime
can be replaced by a serve runtime at any time, so offering the switch is
honest.

The popover consolidates what were two overlapping surfaces (card + detail
popover) into one, and replaces the small radial SVG with a canvas-2D radar
field: self at centre, radius from RTT, node size from shared capacity,
per-node breathing seeded by id hash, real adjacency as spokes, and
non-participant members as a dashed outer band with no size and no capacity.
Visual language follows mesh-llm's own console, drawn in 2D rather than porting
its ~2,200 lines of WebGL -- a 288px popover does not justify shader plumbing.

Nothing animates along a spoke: mesh-llm's counters are node-local with no
per-edge attribution, so a travelling packet would be invented. Motion is
confined to node breathing and a centre pulse driven by real inflight work.

Row and popover share one useMeshComputeState hook rather than each calling the
polling hooks, which would double every poll and let the two disagree
mid-flight.

25a9cf1be6 feat: paste composer text without formatting (#4801)
## Summary

- handle Cmd+Shift+V on macOS and Ctrl+Shift+V on Windows/Linux in the
message composer
- read plain text through the native Tauri/arboard clipboard path in
packaged builds, with a browser-only Clipboard API fallback
- re-enter ProseMirror's paste pipeline with populated `text/plain`
clipboard data so selection, undo, multiline behavior, and paste
observers remain intact
- cover both platform mappings with rendered composer E2E tests that
assert the native command path

## Testing

- `pnpm test` — 4,286 passed
- `pnpm check`
- `pnpm typecheck`
- `pnpm exec playwright test composer-selection-formatting.spec.ts
--project=smoke` — 26 passed
- `cargo check --manifest-path desktop/src-tauri/Cargo.toml --workspace
--all-targets --target aarch64-apple-darwin`
- `just desktop-tauri-test` — 2,206 core tests plus integration and
doc-test groups passed
- full pre-push hooks passed

## Manual verification

Physical packaged-app clipboard verification remains recommended on
macOS, Windows, and Linux. The automated E2E uses mocked Tauri IPC but
asserts the native `read_clipboard_text` command is invoked.

a1d78f2959 feat: Buzz entity links — rich preview cards + in-app navigation for repos, PRs, and issues (#4695)
## Summary

Gives Buzz-hosted git entities the same "GitHub-style" chat experience
GitHub links already get: rich preview cards, real titles, and
click-through — except clicks navigate **in-app** to the Projects view
instead of a browser.

- **Spec**: `docs/buzz-entity-links.md` — link scheme, slices, and
deferred work (`buzz://project`, OS deep links, web routes).
- **Canonical `buzz://` deep links**: new
`desktop/src/shared/lib/entityLink.ts` with builders + strict parser for
`buzz://pr?id=…&owner=…&d=…`, `buzz://issue?…`, and
`buzz://repo?owner=…&d=…`, mirrored by a Rust module
(`crates/buzz-cli/src/links.rs`) with a shared golden-format test so the
two implementations can't drift.
- **Preview cards**: `linkPreview.ts` recognizes `buzz://` entity links
*and* HTTPS relay clone URLs (`{origin}/git/<pubkey>/<repo>`, the shape
agents paste today). Both normalize onto the canonical `buzz://` href,
so the two spellings of a repo dedupe to one `Buzz`-provider card
(`BuzzMark` logo) rendered by `link-preview-attachment.tsx`.
- **Title enrichment**: PR/issue cards fetch the real subject from the
relay event (`subject` tag or first content line) via
`useResolvedLinkPreviews.ts`; the cache is community-scoped and reset in
`resetCommunityState()`.
- **In-app navigation**: clicking a card or inline anchor (including
HTTPS relay clone URLs whose origin matches the active relay) routes to
the canonical `30617:<owner>:<d>` coordinate via `goProject()`
(`markdown/entityLinks.tsx`). **Merge dependency: #4671 must merge
first** — route resolution for `30617:` coordinates is implemented on
that branch (`feat/multi-repository-projects`). Entity-link and
external-anchor logic were extracted out of `markdown.tsx` to stay under
the file-size ratchet.
- **Agent side**: `buzz pr open`, `buzz issues create`, and `buzz repos
create` now return a ready-made `link` field (omitted when the relay
returns `accepted: false`), and `base_prompt.md` instructs agents to
paste it verbatim when announcing work.

## Test plan

- [x] Desktop unit tests: pass, including new `entityLink.test.mjs` and
`linkPreview.test.mjs` coverage (golden formats, malformed-link
rejection, clone-URL/`buzz://` dedupe, origin-gated anchor behavior,
label-must-win invariant, cache epoch)
- [x] Rust: `cargo test -p buzz-cli` golden-format test +
accepted/rejected link guard assertions, clippy + fmt clean
- [x] Biome + `tsc --noEmit` clean; pre-push hooks
(desktop-tauri-checks, rust-tests, desktop-test) pass
- [ ] Manual: paste a relay clone URL and a `buzz://pr` link in a
channel — verify one card each, real PR title, and in-app navigation to
the Projects view

65f7a10035 fix(desktop): wait for terminal frame before splash (#4781)
## Summary

- keep the first-open Buzz Term splash pending until the active PTY
delivers its first frame
- retrigger the splash effect when that readiness gate changes
- cover the real bootstrap path so startup latency cannot consume the
animation invisibly

## Verification

- Wes manually verified the first-open animation in the worktree
- `pnpm --dir desktop typecheck`
- `pnpm --dir desktop test` — 4,195 passed
- `pnpm exec biome check src/features/terminal/TerminalBootstrap.tsx
src/features/terminal/TerminalSubstrate.tsx
src/features/terminal/TerminalBootstrap.test.mjs`
- pre-push hooks — branch skew, desktop check, and 4,195 desktop tests
passed

The repository-wide `pnpm --dir desktop check` still reports
pre-existing diagnostics in `personaCatalogRelay.test.mjs` and
`terminal.css`; the three changed files pass Biome directly.

8b8d86c5d2 fix(desktop): integer-align custom reaction emoji (#4779)
## Summary

- remove the fractional half-pixel translation from custom reaction
emoji
- preserve the existing 28px reaction pill, 14×14 glyph box, and
`object-fit: contain`
- add real-app Playwright coverage for integer centering and non-square
intrinsic dimensions

### Related issue

None found. Follow-up to the Buzz emoji-warp investigation.

### Testing

- `cd desktop && pnpm exec playwright test
tests/e2e/custom-emoji.spec.ts --project=smoke` (15 passed)
- `cd desktop && pnpm test` (4,171 passed)
- `cd desktop && pnpm lint` (passed; two pre-existing informational
`useTemplate` diagnostics)
- `cd desktop && pnpm typecheck` (passed)
- `cd desktop && pnpm exec biome check
src/features/messages/ui/MessageReactions.tsx
tests/e2e/custom-emoji.spec.ts` (passed)

Independent review also mutation-tested the regression coverage by
restoring the half-pixel transform and confirming the new test fails. No
after screenshot is included because the patch preserves dimensions and
fixes subpixel raster alignment; the real-app test asserts the mechanism
directly.

Validated at `bc95969b21b58d83b7f94de4ad25e499e52b35fb`.

ce3cf3cd25 Polish Huddle voice controls (#4694)
## Summary

- add a visible Stop control for interrupting agent speech
- make push-to-talk available by default while preserving manual mute
controls
- refine agent management, muted audio states, drawer layering, and
return navigation
- suppress duplicate notification sounds for Huddle messages

## Why

Huddles could trap users behind long agent speech, hide useful agent
controls, and leave temporary Huddle state visible after the call. The
drawer also regressed when the terminal substrate began painting behind
the rounded app surface.

## Validation

- `just desktop-ci`
- focused Huddle Playwright coverage for the drawer, speech
interruption, agent picker, and leave navigation

5179726737 fix(local-archive): default both archive settings to enabled (#4750)
## Overview

Both local archive settings — "Archive my agents' observer frames" (kind
24200) and "Archive my agents' turn metrics" (kind 44200) — previously
defaulted to OFF in OSS builds, controlled by build-time env vars. This
had an irreversible cost: observer frames are ephemeral (not stored by
the relay), so any missed events are permanently unrecoverable. This PR
makes both settings default to enabled for all builds and removes the
build-time flag machinery entirely.

## What changed

### Rust

- `observer_archive_default_enabled()` — returns `true` unconditionally;
removed `option_env!("BUZZ_DESKTOP_BUILD_OBSERVER_ARCHIVE_DEFAULT")`
check and `nest_is_dev()` runtime fallback.
- `agent_metric_archive_default_enabled()` — returns `true`
unconditionally; removed
`option_env!("BUZZ_DESKTOP_BUILD_AGENT_METRIC_ARCHIVE_DEFAULT")` check
and its OSS-build test.
- `build.rs` — removed both `rerun-if-env-changed` declarations
(`BUZZ_BUILD_OBSERVER_ARCHIVE_DEFAULT`,
`BUZZ_BUILD_AGENT_METRIC_ARCHIVE_DEFAULT`) and the two baked-env
emitting blocks.

### Build / CI

- `Justfile` — removed `desktop-tauri-test-compiled-flags` recipe (the
dual-compile test machinery).
- `.github/workflows/ci.yml` — removed the "Desktop Tauri compiled-flag
verification" CI step.

### TypeScript

- `useObserverArchiveSeed.ts` — removed `observerArchiveDefaultEnabled`
dep from `ObserverArchiveSeedDeps` and the `policyOn` gate in
`reconcileObserverArchive`; the function now unconditionally calls
`mergeSaveSubscriptionKinds`.
- `useAgentMetricArchiveSeed.ts` — removed
`agentMetricArchiveDefaultEnabled` dep from `AgentMetricArchiveSeedDeps`
and the `defaultOn` flag-check path in `maybeSeed`; the
`hasExplicitChoice` guard is preserved as the sole gate against
re-seeding.
- `LocalArchiveSettingsCard.tsx` — removed `policy` prop,
`observerPolicy` state, and `observerArchiveDefaultEnabled` fetch from
`ObserverArchiveSection`; toggle is now always enabled (just `toggling`
disables it); removed the stale "Always on for internal builds" copy
branch; removed the `observerPolicy !== false` guard from
`handleObserverToggle`.
- `tauriArchive.ts` — updated JSDoc on both default-enabled functions to
reflect always-true.
- `e2eBridge.ts` — changed both mock defaults from `?? false` to `??
true` so E2E tests without an explicit mock override exercise the real
default behavior.

### Tests

- `useObserverArchiveSeed.test.mjs` — replaced `policyOn` dep with
direct merge dep; updated `test_oss_policy_off_no_merge` →
`test_reconcile_always_seeds_24200`; all cancellation, identity-switch,
and ordering tests adapted.
- `useAgentMetricArchiveSeed.test.mjs` — removed `defaultOn` dep and
`test_oss_build_does_not_seed`; updated
`test_internal_build_unset_seeds_*` → `test_default_enabled_*`;
`hasExplicitChoice` guard tests unchanged.

## Preservation of explicit opt-outs

Users who have previously toggled the setting off are unaffected:

- `useAgentMetricArchiveSeed` skips seeding when
`hasExplicitChoice(pubkey)` returns true (localStorage-persisted per
identity).
- Observer archive reconciliation now unconditionally calls
`mergeSaveSubscriptionKinds`, but a user who already deleted the
subscription can turn it off via the Settings toggle, which calls
`removeSaveSubscriptionKind` — this is the existing explicit opt-out
path, and the toggle is now always enabled (not locked by a policy
flag).

## Result

- No `BUZZ_BUILD_*_ARCHIVE_DEFAULT` /
`BUZZ_DESKTOP_BUILD_*_ARCHIVE_DEFAULT` references remain outside
CHANGELOG/history.
- Desktop node tests: 4168 pass, 0 fail.
- `just desktop-tauri-check`: clean.
- `just desktop-tauri-test`: all pass.

e5efd04705 fix(desktop): close reconnect gaps that previously required CMD+R (#4737)
> Opened by Brain (agent) on behalf of @wesbillman.

## Problem

Users report the desktop app doesn't reliably reconnect and can wedge in
states where only CMD+R (or a full restart) restores connectivity
(thread `c2205e2b` in #desktop-reconnecting).

Pinky's empirical light-switch matrix (real `buzz-relay`, SIGTERM/1012 +
SIGKILL × 1s/45s/3min, at `f18a9cb10`) passed 4/4 — the backoff state
machine recovers cleanly from ordinary relay loss. That isolates the
user-stuck states to four special cases a reload resets but the auto
flow never did.

## Fixes

| Gap | Change |
|---|---|
| **G1** — recovery rode solely on the backoff timer (max 30s),
throttled by WKWebView in occluded/background windows; nothing fired on
network return or wake | New `useRelayResumeTriggers`: `online`, window
focus, and visibility→visible call `preconnect()` when the session is
`reconnecting`/`stalled`, rate-limited to one attempt per 5s
(`relayResumeTriggerPolicy.ts`). Deliberately inert for the terminal
`disconnected` state. |
| **G2** — any AUTH `OK false` latched the session terminal forever,
though the relay also rejects for transient causes (duplicate-AUTH
"already authenticated" race, ±60s clock skew, fail-closed allowlist DB
errors) | New `AuthOkTracker` (`relayAuthPolicy.ts`): "already
authenticated" resolves as success; transient rejections retry with
normal backoff; latch only on `restricted:` or after 3 consecutive
rejections. |
| **G3** — an `auth-required:` CLOSED (REQ racing AUTH after reconnect)
permanently deleted the live subscription with no UI signal — frozen
channel while state reads "connected" | Reclassified `auth-required:` as
retryable in `relayClosedPolicy.ts`. Genuinely terminal classes
(`restricted:`, `invalid:`, …) still delete. Can't loop: a truly
unauthenticated session latches terminal at the connection level. |
| **G4** — `useRelayAutoHeal` observed the 2s-debounced connection hook,
so sub-2s flaps never triggered the heal even though `resetConnection`
had already rejected every in-flight query | Auto-heal now observes the
raw connection-state emitter. The existing 15s heal rate-limit still
guards against flap storms. |

Each fix is a colocated pure-policy module + unit tests, matching the
existing `relayReconnectPolicy`/`relayClosedPolicy` pattern.

## Validation

- Full desktop unit suite: **4151 pass, 0 fail** (at branch tip, `pnpm
-C desktop test`)
- `pnpm -C desktop typecheck` and `pnpm -C desktop check` clean
(file-size ratchet respected — `relayClientSession.ts` net −2 lines
despite the tracker wiring)
- Evidence trail: `RESEARCH/DESKTOP_RECONNECT_CMDR_GAP_AUDIT.md`
(audit), `RESEARCH/DESKTOP_RECONNECT_LIGHT_SWITCH_RESULTS.md` (Pinky's
matrix)

## Not covered / follow-ups

- Native macOS sleep-wake was not automated (would kill the harness
session); G1's focus trigger is the mechanism that covers wake in
practice, but a manual sleep-wake verification on a real build is
worthwhile.
- G3 terminal-CLOSED classes (`restricted:` etc.) still silently delete
subs with no UI signal — surfacing that is a separate UX decision.
- Stall-watchdog latency (60s idle + 10s check) left unchanged; G1
triggers largely mask it.

cb4a73e17d Dock Buzz Term within channel workspace (#4724)
## Summary

- replace Buzz Term's full-app takeover with a resizable bottom dock
inside the channel content surface
- add a discoverable channel-header button plus hide and
maximize/restore controls
- create PTYs lazily and keep separate, persistent terminal workspaces
per channel
- capture immutable channel/thread context on every terminal session

## Multiple-channel behavior

The dock is a single surface, but its tabs are partitioned by channel.
Switching channels swaps to that channel's sessions without terminating
background PTYs; returning restores them. New tabs capture the currently
visible channel/thread context.

## Verification

At commit `7ca087f8e08c80528387684364a65bf4ccd6315f`:

- `pnpm --dir desktop typecheck`
- `pnpm --dir desktop test` — 4,129 passed
- pre-push repository hooks — desktop check/test, Tauri checks, terminal
Rust suites all passed

0afeac8a7c feat(desktop): persist sidebar observed-unread across webview reload (#3976)
## Problem

`Command+R` (webview reload) wipes the two in-memory refs driving
sidebar channel unread badges: `observedUnreadEventsByChannelRef` and
`latestByChannelRef`. The boot catch-up REQ can only fetch events newer
than each channel's NIP-RS frontier, so thread replies that arrived
before the frontier was passively advanced (the common case) are never
re-discovered.

Inbox is unaffected because it rebuilds candidates from a relay feed
query and checks fine-grained `thread:`/`msg:` markers. The sidebar
badge path lacks an equivalent recovery mechanism.

## Solution

Persist the sidebar's per-event candidate set to localStorage as a
disposable, versioned projection cache
(`buzz-observed-unread.v1:<relay>:<pubkey>`) and hydrate it on boot
before the catch-up REQ runs.

### New files

**`observedUnreadStorage.ts`** — storage module for the cache:
- Keyed
`buzz-observed-unread.v1:<normalizedRelayUrl>:<normalizedPubkey>`
(relay-scoped to prevent cross-community leakage, matching
`threadActivityStorage`)
- Stores validated per-event `ObservedUnreadEvent` rows;
`latestByChannel` is derived at hydration — no divergent dual aggregate
- Age pruning (7d = `READ_STATE_HORIZON_SECONDS`), per-channel cap
(1000), global cap (5000) across all channels in a scope bucket
- Payload `updatedAt` for LRU ordering; registered in
`PURE_CACHE_KEY_PREFIXES` for 2 MiB eviction budget
- Field-level validation on decode; write failure is non-fatal
(session-only degradation)
- Snapshot-owning timers: `scheduleObservedUnreadWrite` deep-clones the
events map at schedule time — a late A-scope timer can never read B's
mutable refs or write under B's key

**`useObservedUnreadPersistence.ts`** — hook that owns all persistence
lifecycle:
- Scope fence: `normalized pubkey + normalized relay` identity;
`isScopeLoaded()` callback guards both projection (`rawUnread`) and
every **observed-cache mutation** (`recordUnreadEvent`, `removeChannel`,
`clearAll`) before touching refs or storage. Note: stale-scope calls to
`markChannelRead`/`markAllChannelsRead` can still affect
`forcedUnreadRef` and NIP-RS markers, which are pre-existing on `main`
and deferred to the NIP-RS arc (see Deferred below).
- Synchronous `pagehide` flush closes the Cmd+R timing gap
(`useReloadShortcut.ts` reloads within 500ms of teardown, before the
1-second debounce fires)
- Identity-reset effect: flushes old scope, resets refs, hydrates from
storage, stamps loaded scope — all atomic; cleanup flushes on unmount
- `clearAll` cancels the pending timer, resets both in-memory refs, and
clears storage in a single transactional operation; `removeChannel`
deletes the channel from both refs and replaces any pending snapshot
with the current full map — never cancel-without-replacement, preserving
sibling-channel events on reload
- Marker-prune effect on `readStateVersion`: evaluates each retained
event with `observedUnreadEventReadAt()` (the same evaluator used by the
projection memo) and removes covered events, rederiving per-channel
latest — never clears a whole channel for a single thread/msg marker
- Returns a stable `useMemo`-wrapped API object keyed on actual deps so
unrelated re-renders do not restart the catch-up REQ
- `isScopeLoaded` is a `useCallback` (not a memoized boolean) — always
reads the ref at call time, never stale

### Modified files

**`useUnreadChannels.ts`** — hook integration:
- Calls `useObservedUnreadPersistence` with all persistence wired
through the returned API
- `rawUnread`: `isScopeLoaded()` guard suppresses A-scope refs from
projecting under B
- `recordUnreadEvent`: `isScopeLoaded()` fence before touching refs;
schedules a debounced write on each successful record
- `markChannelRead` clearObserved path: calls `removeChannel` so the
cleared state survives reload
- `markAllChannelsRead`: delegates to the owner's fenced `clearAll` —
the parent does not reset the observed refs directly; `clearAll` owns
the transactional clear of both refs and storage, preventing a stale
scope-A callback from corrupting scope B

**`localStorageQuota.ts`** — registers `buzz-observed-unread.v1:` in
`PURE_CACHE_KEY_PREFIXES`

## Design constraints

The cache is a **disposable projection**: versioned key, read-through
only, safe to delete wholesale. It does not touch `ReadStateManager`,
marker semantics, or `forcedUnreadStore`. Zero overlap with the NIP-RS
manual mark-read/unread protocol work in progress in another channel;
migration path when that lands is "stop reading the key."

## Test coverage

**`observedUnreadStorage.test.mjs`** covers storage primitives:
- Key normalization, relay-scoped isolation, round-trip correctness
- Age-prune and per-channel cap on read and write; global cap across
channels
- `deriveLatestByChannel` correctness
- Thread-marker prune leaves sibling thread events persisted and lit
- Scope-isolation state machine: A rows visible in A, absent in B,
restored on A again; late A-scope write does not overwrite B's bucket
- Malformed structures/fields, relay/pubkey isolation, quota failure
degradation

**`useObservedUnreadPersistence.test.mjs`** exercises the real hook via
`createRoot` + `act`:
- pagehide flush: event recorded within debounce window survives reload
(headline regression)
- Unmount with pending write flushes before teardown
- `clearAll` cancels pending debounce so no resurrection after reload
- `removeChannel` replaces pending snapshot so sibling channel B
survives reload (two-channel repro)
- Marker prune: thread and channel markers prune covered events; sibling
channels survive
- `isScopeLoaded` returns false before identity-reset effect commits,
true after
- A→B scope switch: pending A-timer is cancelled by flush, A data
persisted synchronously (hydration round-trip)
- Stale `clearAll` from scope A rejects after scope B loads
(observed-cache scope fence)
- Stale `removeChannel` from scope A rejects after scope B loads
(observed-cache scope fence)
- API object identity stable across unrelated re-renders (catch-up
stability)

**`useUnreadChannels.test.mjs`** exercises the full parent-to-owner seam
with real hook mounts:
- Stale `markChannelRead` from scope A does not corrupt B's observed
bucket after flush
- Stale `markAllChannelsRead` from scope A does not overwrite B's bucket
after flush

## Deferred

Issues deferred to the NIP-RS arc (`#unread-messages-ux`) or future
hardening — not regressions introduced by this PR:

- **Stale-scope `forcedUnreadRef` / `markContextRead` exposure**: a
stale scope-A `markChannelRead` or `markAllChannelsRead` still deletes
B's `forcedUnreadRef` entries and advances B's NIP-RS markers via
`markContextRead` before the observed-cache fence rejects. This is
pre-existing on `origin/main` (identical shape at lines 316/330). Fix
requires touching `forcedUnreadStore` and marker paths — out of scope
for Fix A. Deferred to the NIP-RS work.
- **`isScopeLoaded` empty-scope hardening**: `isScopeLoaded()` returns
`true` when `pubkey` and `relay` are empty strings (no active session).
A guard could assert non-empty identity before stamping scope-loaded.
Low risk in practice since the hook is only mounted after auth, but
could be tightened.
- **Catch-up batch scheduling**: `handleChannelMessage` and the catch-up
loop each clone the full events map per event via
`scheduleObservedUnreadWrite`. For channels with large backlogs this
produces O(n) snapshot clones per catch-up batch. A batch-schedule API
(single snapshot at end of batch) would reduce allocations. Not
observable in normal use; deferred as a performance optimization.
