Taylor HoandGitHub 5677e4ca05 test(desktop): match attachment button label (#4993)
**Category:** fix
**User Impact:** Pull requests can once again pass the Desktop smoke
test suite.
**Problem:** The inbox attachment-edit smoke test still looked for the
composer's former “Attach image” label after the shared action was
renamed to “Attach file,” causing shard 3 and the aggregate Desktop CI
job to fail on every PR.
**Solution:** Update the stale accessible-name selector to match the
current composer control while preserving the test's media-tag coverage.

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

**desktop/tests/e2e/inbox-edit.spec.ts**
Updates the attachment button selector to use the current accessible
label so the existing attachment-edit regression test reaches the
behavior it is meant to verify.

</details>

## Reproduction steps

1. Build the Desktop E2E application with `pnpm -C desktop build:e2e`.
2. Run `cd desktop && pnpm exec playwright test --project=smoke
tests/e2e/inbox-edit.spec.ts -g "editing an immediate attachment reply
preserves its media tags"`.
3. Confirm the test locates the “Attach file” control and passes.

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,
desktop-check, desktop-test, rust-tests, desktop-tauri-checks)

Part of the rate-limiting fix stack; independent of
`eva/rate-limit-fixes` by design (separate minimal PR per Tyler's
ruling).

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

Originating Buzz thread:
`buzz://message?channel=3928fe05-df61-4b5d-b9c7-d623b9b10ea1&id=3c6c02312f763fbe0d2bfc33a6c1a362f91d0354f3d18b039cf7a0558c1439d1`

06b60e682d fix(mobile): merge relay recounts with locally seen thread replies (#4633)
## Summary

- Keep mobile thread reply badges current by merging relay recounts with
replies observed locally.
- Retain replies in the local channel store while continuing to filter
them from the main timeline.
- Match the thread summary behavior already used on desktop, including
the reply count, latest reply time, and participant avatars.

## Why

On mobile, the "N replies" badge under a channel message can stall at a
stale count or remain missing after a reply arrives. This makes the
badge unreliable and can cause people to miss replies.

The badge has two inputs: best-effort recounts from the relay and
replies the client sees arrive. Mobile previously let any positive relay
recount override the local view, while also discarding replies from its
local message store. A delayed or lost recount, or a reply received
after the recount, could therefore leave the badge behind.

This change combines both inputs by using the higher reply count, the
later last-reply time, and a merged participant list. Relay timestamps
have one-second precision, so equal timestamps do not prove that a
recount included a locally observed reply. Comparing counts preserves
that reply instead of trusting recency alone. Desktop already uses this
merge behavior.

## Validation

At commit `4e3356636f5ad62e8f07910af305c532186c6c08` with a clean
worktree:

- `flutter test` for mobile: 1105 passed, 1 skipped
- `flutter analyze` for mobile: no issues found
- Reverting the merge so a positive relay recount shadows local replies
fails 4 of the new tests, including the same-second and
reply-after-recount cases. Restoring the store-level reply drop fails
both new provider tests.

Added tests:

-
[`timeline_message_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/features/channels/timeline_message_test.dart),
covering relay-only recounts, a reply newer than the recount, a reply in
the same second as the recount, a lost recount, a zero recount, nested
replies at the root and at the reply they answer, a deleted reply, and
participant merging and capping.
-
[`channel_messages_provider_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/features/channels/channel_messages_provider_test.dart),
covering a live reply reaching the store while staying out of the main
timeline, and a reply newer than the relay recount raising the badge.

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
detail](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/2198/inbox-edit-before.png)
| ![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)
-

e14fff74d0 relay: fuzz WebSocket 1012 restart-close timing on graceful drain (BUZZ_DRAIN_JITTER_MS) (#4542)
## Problem

On SIGTERM the relay sends every live WebSocket a **1012 Service
Restart** close frame via `ConnectionManager::drain_all()` — all in the
same instant (`main.rs` shutdown task → `state.rs::drain_all`). On a pod
holding thousands of sessions, that makes every client reconnect
simultaneously: the thundering-herd reconnect behind the DB pool-timeout
bursts observed on each rolling deploy. Client-side jitter can't fix
this — the desktop client *resets* its backoff to base on a 1012 and
reconnects with only ±25% jitter (`relayClientSession.ts`), so the
spread has to come from the server.

## Change

Add `BUZZ_DRAIN_JITTER_MS` (default `0` = unchanged behavior). The two
paths are kept **deliberately separate** so the default is byte-for-byte
the previously shipped shutdown:

- **Jitter off (`0`/unset, the default):** the original synchronous,
all-at-once `drain_all()` runs unchanged — queue the 1012 on each
connection's control channel, cancel, return. No new machinery on the
default path.
- **Jitter on (`> 0`):** a separate async
`drain_all_jittered(jitter_ms)` spreads each connection's restart close
over an independent uniform delay in **`[1, jitter_ms]`**. Each delayed
close travels a dedicated `RestartClose` channel; the writer flushes the
1012 frame and **acknowledges the flush over a oneshot**, so drain waits
for confirmed delivery (up to `RESTART_CLOSE_ACK_TIMEOUT` = 5s) rather
than assuming it, falling back to cancellation if the channel is
full/closed or the ack times out. The drain future is **owned and
awaited** by the shutdown task, and the 30s hard-drain backstop is
aborted only after a clean drain — so a clean roll exits `0`.

The two methods can be unified and the old one dropped later once the
jittered path is proven for all cases.

- **`config.rs`** — `drain_jitter_ms`: non-negative parse, clamped to
`MAX_DRAIN_JITTER_MS` = **20s** (leaving 10s of the 30s budget for
flush). Junk fails loudly at startup; **empty/whitespace-only is treated
as unset (jitter off)** so a `BUZZ_DRAIN_JITTER_MS=""` kill switch does
not crashloop the relay (matches the sibling env vars in this file).
- **`state.rs`** — `drain_all()` (unchanged synchronous default) +
`drain_all_jittered()` (jittered + flush-ack). Both set the sticky
`draining` flag before the first await. A registration that lands
mid-shutdown always self-signals via the **immediate** control-frame +
cancel path — jitter smears already-established sockets, not late
arrivals.
- **`main.rs`** — shutdown task dispatches: `drain_jitter_ms == 0` →
`drain_all()`, else `drain_all_jittered(...).await`.

## Safety

- **Default off is the currently-committed path.** With jitter unset/0
the shutdown runs the original synchronous `drain_all()` — no restart
channel, no ack wait. Safe to deploy dark and dial up.
- **Shutdown-boundary race preserved.** Sticky flag set before any
await; a late registration self-signals its close with no jitter.
- **Owned + backstopped.** The jittered drain future is awaited; the 30s
hard-drain `process::exit(1)` remains the ceiling. `MAX_DRAIN_JITTER_MS`
(20s) + `RESTART_CLOSE_ACK_TIMEOUT` (5s) = 25s, inside the 30s budget;
5s pre-sleep + 25s = 30s against `terminationGracePeriodSeconds: 60`.

## Known behavior to note (not a blocker, flagged from review)

On a **successful** flush the jittered path deliberately does not cancel
the connection token — teardown then depends on the client echoing our
Close, or on process exit. Compliant clients echo; a silent client rides
to the 30s hard exit. The default (jitter-off) path cancels
deterministically as before.

## Tests

- `config::tests::drain_jitter_defaults_off_and_rejects_junk` — default
off, `20000`, clamp `60000`→`20000`, explicit `0`, junk `"soon"` fails,
**empty `""` and whitespace-only treated as off**.
- `state::tests::drain_all_is_immediate` — default path queues frame +
cancels synchronously.
- `state::tests::drain_all_sends_restart_close_and_cancels_every_conn`,
`drain_all_full_control_buffer_still_cancels`,
`register_after_drain_self_signals_restart_close_and_cancel`.
-
`state::tests::drain_all_jittered_defers_close_until_within_jitter_window`
(paused time).
-
`state::tests::drain_all_jittered_waits_for_writer_acknowledgement_without_cancelling`.
-
`state::tests::drain_all_jittered_cancels_when_restart_channel_is_full_or_closed`.
- `state::tests::drain_all_jittered_cancels_when_flush_ack_times_out`
(paused time — the 5s ack-timeout fallback).

Validation at `46c690940`: `cargo fmt -p buzz-relay --check`, `cargo
clippy -p buzz-relay --all-targets -- -D warnings`, and the drain/config
unit suite all clean. Local live SIGTERM test with a real relay process
+ 200 NIP-42-authenticated sockets — see the PR comment for the
before/after distribution and exit codes.

## Rollout

Ship with default `0`, then set `BUZZ_DRAIN_JITTER_MS` (e.g.
10000–20000) on bb-block first, watch the roll-window pool-timeout
metric, then bb-public. `""` is a safe kill switch. Complements the
preStop `sleep` (stops routing before close).

Taylor HoandGitHub 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.

**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.

Taylor HoandGitHub 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`

Taylor HoandGitHub 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**

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

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"`

ed4b3e7afa fix(buzz-agent): recover from context-window 400s instead of sticking (#4946)
Provider `context_length_exceeded` 400s permanently wedged agent
sessions: the turn errored, the oversized history persisted in the
in-memory session, and the usage baseline stayed frozen at the last
successful sub-threshold reading (failed requests report no usage), so
the preflight handoff gate never fired again — every later prompt failed
identically until an agent restart. The byte-truncation fallback never
intervened because it is a request-body limiter (`estimated_bytes`), not
a context-window defence; at context-window scale it is a measured
no-op.

This adds the reactive recovery path:

- **Typed classification.** `AgentError::LlmContextExceeded` is
classified at both non-success provider terminals — the shared `post()`
(Anthropic, OpenAI, Databricks) and `openrouter_post()` — on `status ==
400` plus a context-window body match, so ordinary 400s stay terminal.
- **Forced handoff.** A context-400 forces a summarize-handoff that
bypasses `should_handoff()` and `BUZZ_AGENT_MAX_HANDOFFS`, bounded by
its own per-turn budget (`MAX_CONTEXT_RECOVERIES_PER_RUN = 3`).
- **Shrink ladder.** The summarize prompt budget halves from the
observed rejected history size — not from `max_context_tokens`, the
number the provider just contradicted — rung to rung, with a 4096-byte
floor. A summarize call rejected for the same reason takes the next rung
instead of re-sticking. At the floor (overflow dominated by unshrinkable
frame: system prompt, tool schemas, live prompt) recovery is refused and
the provider error surfaces clearly instead of self-healing.
- **Baseline reset.** The stale usage baseline is cleared when a request
fails, so the preflight gate cannot stay frozen sub-threshold on
retries.

Named behavior changes:

1. **Anthropic and OpenRouter errors now carry the `(model)` stamp.**
Provider arms return their `Result` into the central error mapper
instead of early-returning past it, making the code match its documented
single-convergence contract at that mapper.
2. **`max_rounds` now counts completions the loop acts on.** A request
rejected with a context-400 that is then successfully recovered refunds
its round before the retry, paired 1:1 with a consumed recovery rung, so
the round cap is neither weakened nor able to drop a recovered turn
unanswered.

Related: #4805 — the complementary proactive fix (per-session
handoff-cap kill switch that let sessions grow to the provider wall).
#4805 prevents reaching the wall; this PR recovers at it.

ccdaa16161 docs(persona-pack): fix stale desktop import instructions (#4500)
## Summary

The desktop app no longer imports persona packs the way the docs
described. `PERSONA_PACK_SPEC.md` and the `meadow-core` example still
pointed users at a `.zip` import through "My Teams / My Agents → Import"
and a future "Install Pack" button — none of that exists anymore. The
app only imports agent/team **snapshots** (`.agent.json`/`.agent.png`,
`.team.json`/`.team.png`), and a persona-pack `.zip` is explicitly
rejected.

## Fix

Updated both docs to describe the current import paths (Agents / Agent
teams sections, snapshot files only) and added a note that persona packs
and desktop snapshots are separate, non-interchangeable formats today.

Fixes #4468

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 \

05150c1188 feat(mobile): sync themes per community (#3767)
**Category:** new-feature
**User Impact:** Mobile now keeps each community’s appearance in sync
with desktop, including theme, accent, and system-mode preference.

**Problem:** Appearance choices were device-local, so the same account
could look different between desktop and mobile. Live sync could also
stop after the relay closed a subscription.

**Solution:** Store each community’s encrypted appearance preference on
its relay using the shared desktop wire contract, restore it from a
local identity-scoped cache, and apply replacement events live. Closed
subscriptions now recover with guarded backoff and fetch the latest
preference so no update is lost during the gap.

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

**mobile/lib/app.dart**
Connects community appearance state to the authenticated app lifecycle.

**mobile/lib/features/settings/accent_picker_page.dart**

</details>

## Reproduction steps

1. Sign into desktop and mobile with the same account and join the same
community relay.
2. On desktop, choose a distinctive non-Buzz theme and accent; mobile
should update without a local toggle.
3. Restart mobile and confirm it restores the same appearance.
4. Change the mobile theme and accent and confirm desktop follows.
5. Leave mobile idle or backgrounded through a relay reconnect, then
change desktop again; mobile should resubscribe and catch up
automatically.
6. Switch communities and confirm each community restores only its own
appearance.

43cced308d feat(desktop): sync themes per community (#3653)
**Category:** new-feature
**User Impact:** Users can keep a distinct Appearance scheme for each

### 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`

6df7eba24d fix(buzz-agent): scope handoff cap per turn, not per session lifetime (#4805)
`BUZZ_AGENT_MAX_HANDOFFS` compared against the session-cumulative
`handoff_count` (persisted across prompts). After N handoffs a
long-lived session hit the cap permanently: `maybe_handoff()` returned
`Skipped` on every subsequent prompt, the 16 MiB byte-truncation
fallback never bound before a 1M-token provider wall, and the session
wedged on the first 400 with no recovery path. Thufir's session log
shows 8 days of cap-forced truncation before the first
`context_length_exceeded` 400.

The fix replaces the session-level cap comparison with a local
`handoff_attempts` counter constructed at the start of `run()` and
passed into `maybe_handoff()`. The counter resets on every
`session/prompt` turn so `BUZZ_AGENT_MAX_HANDOFFS` caps compaction loops
within a single turn while allowing unbounded compactions across a
session's lifetime. The session-cumulative `handoff_count` is retained
for log context only and is not reset. Steer-driven rounds share the
per-turn budget automatically since steers inject into the running
`run()` loop, not a new call.

- Move `handoff_attempts` increment to before `summarize()` so failed,
empty, and cancelled summarize calls each consume one budget slot — the
cap cannot be bypassed by a repeatedly-failing summarizer
- Upgrade cap-forced `Skipped` from `INFO` to `WARN`; add structured
fields for `session_id`, attempt count, projected tokens, and threshold
so the cap→wall pairing is attributable per session
- Document `max_handoffs` in `config.rs` as a per-`session/prompt`-turn
bound
- Three new behavioral regression tests: per-turn reset proven across
two separate turns; within-turn cap proven via multi-round tool-call
turn; failed summarize proven to burn the attempt budget

Note: this is the proactive half of the context-window fix. The reactive
`context_length_exceeded` 400 recovery path is owned by Sami's branch
(`buzz-ctxfix-sami`, Tyler's crew); this PR is intended to land after
that one.

4674750b7e fix(release): tag immutable desktop candidates (#4811)
## Summary

Redesign the permanent Desktop release flow so unrelated merges to
`main` cannot invalidate an already reviewed, green release candidate.

- Tag the immutable, API-confirmed release PR head instead of its later
squash commit.
- Treat the merged PR—including an authorized owner/admin bypass—as
publication authorization, while requiring trusted check evidence that
was complete at merge time.
- Make tag creation idempotent and collision-safe: an existing tag
succeeds only at the exact candidate SHA, and create races refetch
before accepting equality.
- Replace ancestry-based previous-release discovery with a validated
metadata ledger for side-history candidate tags.
- Compute the next release from the prior frozen base to the new frozen
base, excluding only the prior release squash SHA so unrelated commits
remain in the changelog.
- Preserve schema-1 production-tag migration and reject malformed
metadata or equal/decreasing versions.
- Update operator documentation for the normal squash-merge workflow.

This is the reusable release process for `0.5.6` onward, not the retired
one-shot `0.5.5` recovery path.

### Invariants covered

- Candidate creation → unrelated `main` merge → authorized squash merge
→ immutable candidate tag.
- Trusted producer IDs and merge-time completion timestamps; DCO's
bounded post-merge exception remains isolated.
- Missing/spoofed checks, tampered candidates, ambiguous PR
associations, conflicting tags, and equal/decreasing versions fail
closed.
- Same-SHA retries succeed; different-SHA collisions fail.
- Legacy schema-1 tag-on-main migration and schema-2 side-history
accounting both preserve the correct next-release changelog.

### Related issue

N/A — follows the Desktop release failures in #4788 and #4800 and the
recovery revert in #4808.

### Testing

At clean commit `6a91fbed8147a48cf174997de0c3e4cb2fb26474`:

- `scripts/test-desktop-release-candidate.sh`
- `scripts/test-release-ref-contract.sh`

Both focused suites passed with HEAD unchanged. Princess Donut cleared
the security/provenance surface, including the hostile merge-time
timestamp cases. Mongo cleared the side-history ledger, migration,
version-order, documentation, and contract-test surface.

ad538bfb1e fix(acp): reject unattended permission requests (#4609)
This change removes the ACP permission-bypass mode, defaults managed
sessions to `dontAsk`, and answers permission requests with
`reject_once` or cancellation in both ACP read loops.

Unattended operations that require interactive approval now fail closed
instead of being silently authorized. Explicit non-interactive modes
that do not bypass a permission request remain available.

Both layers have to change together: `apply_permission_mode` treats an
unsupported mode and a failed `set_config_option` as non-fatal by
design, so a request can still reach the harness even in a
non-interactive mode. Removing `bypassPermissions` from the enum rather
than only changing the default means the mode cannot be restored by
configuration alone.

The scope of the guarantee is that `buzz-acp` never grants approval. An
agent that pre-authorizes tools in its own configuration (for example
Claude Code's `settings.json`) still runs them without asking, which is
outside this harness.

## Testing

- `env -u BUZZ_ACP_LAZY_POOL bin/cargo test -p buzz-acp` at `16fff4d`:
671 library tests and 9 integration tests passed
- `cargo clippy -p buzz-acp --all-targets -- -D warnings` and `cargo fmt
-p buzz-acp -- --check`: clean
- `git diff --check
origin/main...codex/security-acp-shell-auto-approval`

The permission tests previously re-implemented the `reject_once` lookup
in the test body instead of calling the code under test, so they would
have passed unchanged if the harness went back to selecting
`allow_once`. They could not call it directly, because
`handle_permission_request` is a method on `AcpClient`, which owns a
live `Child` and its stdio pipes. The choice is now a free function,
`permission_denial_response`, and the tests exercise it: `reject_once`
preferred over offered allow options, the cancelled fallback when no
`reject_once` exists, an empty option list, and a `reject_once` missing
its `optionId`. The cancelled fallback had no coverage before despite
being the fail-closed backstop.

## Operator notes

- `BUZZ_ACP_PERMISSION_MODE=bypassPermissions` no longer parses, so a
process configured with it fails to start rather than silently

- Desktop managed agents do not set a permission mode, so they inherit
`dontAsk`. The desktop has no permission prompt, so operations needing
approval now fail with no in-app way to approve them.

Jordan MecomandGitHub 885bed35ee fix(workflow): bind trigger author to the signed event (#4607)
This change derives `trigger_author` exclusively from the signed event
pubkey. Actor tags remain available as event data but cannot override
the identity used by author-sensitive workflow conditions.

This removes the impersonation path without changing workflow
definitions or requiring stored-data migration.

## Testing

- `bin/cargo test -p buzz-workflow` at `78819df`: 154 passed, 2
Postgres-dependent tests ignored
- `git diff --check
origin/main...codex/security-workflow-trigger-author`

997b8caaa4 fix(git): revoke access for banned relay members (#4608)
This change rechecks the durable community ban in the shared Git HTTP
authentication path for advertise, fetch, and push requests. A banned
member is denied even if repository-channel membership still exists, and
restriction lookup errors fail closed.

The additional database lookup happens on every Git HTTP request so
access revocation does not depend on stale session state.

The check also cascades to the NIP-OA owner. Git accepts NIP-OA
attestations on the NIP-98 token, so an agent key can act for its owner
— without the cascade, a banned human would keep clone and push access
through any agent key. This mirrors the NIP-42 gate in `handlers::auth`:
either principal's ban denies the request.

The check runs inside the `GitAuth` extractor, so all three Git routes
inherit it.

## Testing

- `git diff --check origin/main...codex/security-ban-revokes-git`
- Rebased onto `origin/main` at `5c98932`
- `cargo test -p buzz-relay --lib sec005_read_gate_tests`: 8 passed, 7
ignored (Postgres)
- `cargo clippy -p buzz-relay --all-targets -- -D warnings` and `cargo
fmt --check`: clean

Pure tests cover the decision table (agent ban, inherited owner ban, no
attestation). Postgres-gated tests cover the wiring: the real ban row, a
live `compute_auth_tag` attestation, and the 503 fail-closed path.

**Not yet verified:** the three Postgres-gated tests compile and skip
but have not been run — no local Postgres, and CI does not run
`--ignored`. They need `cargo test -p buzz-relay --lib
sec005_read_gate_tests -- --ignored` against a migrated dev database.

8a7eb8d3d7 fix(agent): recover from unsupported image input instead of poisoning the turn (#4896)
## Problem

`buzz-dev-mcp` advertises `view_image` to every agent regardless of
whether the session's model accepts images. When a text-only model (e.g.
DeepSeek V4 Flash) takes the bait, the image lands in session history
and every subsequent LLM request 404s with `No endpoints found that
support image input`. The error was classified as `LlmModelNotFound` and
propagated fatally out of the turn loop — history stays poisoned,
buzz-acp retries the batch with exponential backoff, and the session
burns its entire clock doing no work. In a recent trial run, **all 57
trials that called `view_image` on a text-only model died this way; none
recovered.**

## Fix

Capability-gating the advertised tool isn't reliable — there is no
image-capability metadata at the agent layer across providers. Instead,
recover at the turn loop:

- **Typed error**: new `AgentError::UnsupportedImageInput`, classified
narrowly on the exact provider phrase `No endpoints found that support
image input` on both the generic 404 path and OpenRouter's 404 path.
Unknown-model 404s and OpenRouter parameter-routing 404s keep their
existing classifications. No deterministic retry.
- **In-turn recovery**: on this error, `RunCtx::run` strips every image
block from history — keeping the tool result (and therefore
tool-call/result pairing) intact — marks the result `is_error`, appends
actionable model-facing guidance ("The current model does not support
image input. The image was removed from conversation history so this
turn can continue. Use a text-based inspection tool…"), and continues
the same turn. Base64 never replays again.
- **Loop guard**: recovery only fires when at least one image was
removed; if the provider says "image" and history has none, the error
propagates as before.

## Tests

- Unit: phrase classification (typed, not retried; unknown-model 404
unaffected), idempotent image-to-error history mutation preserving call
IDs and text.
- End-to-end (`fake_llm.rs` + `fake_mcp.rs`): tool call → MCP image
result → 404 unsupported-image → same-turn recovery. Captured requests
prove round 2 carried the image, round 3 replays no image, carries the
guidance text, preserves pairing, and ends `end_turn`.
- Loop guard: typed unsupported-image error with **no** image in history
fails after exactly one provider request instead of spinning —
mutation-testing showed deleting the `removed == 0` guard survived the
suite, and `max_rounds` defaults to unlimited in production, so this
branch needed direct coverage.

Verified at `a210305019b33d5f56677b4c82bab79e4ac52d24`: `cargo test -p
buzz-agent` (full package, 381 unit + all integration suites) green;
`clippy --all-targets -D warnings` green; `fmt --check` green; pre-push
hooks (rust-tests, desktop-tauri-checks, branch-skew) green.

**Scope of the classification guarantee**: the classifier runs in the
shared `post()` (which Anthropic and OpenAI paths route through) and in
`openrouter_post()` — i.e., every 404 path in `llm.rs`. It only runs on
404 responses; providers that reject images with a different status
(e.g. a 400) are out of scope for this PR — see the review-comment
discussion for why broadening the phrase list alone would not cover
them.

067c085f37 Define private managed agent wire protocol (#4593)
## Summary

- reserve kind `30179` for owner-private managed-agent aggregates
- define the fail-closed owner-self NIP-44 v2 envelope and versioned
payload codec
- bind runnable identity/configuration to complete signed
`30175`/`30177` recovery projections
- validate NIP-OA owner→agent attestations and reject self-attestation
- document NIP-PMA authority, migration prerequisites, privacy, and
deployment order
- keep generic relay ingest closed until private storage and atomic
aggregate CAS exist

## Safety boundary

This is the inert protocol/codec slice only. It does not publish
secrets, change agent authority, migrate local records, or enable kind
`30179` ingestion. The relay regression test proves generic EVENT ingest
still rejects the kind.

The finalized migration plan adds later prerequisites for relay-private
storage/CAS, runtime lease/fencing, Desktop cutover, and harness
authentication. Those belong in staged follow-up PRs rather than
expanding this inert foundation.

## Validation

At commit `67f0ea4ebb8d3ccba3a3eb9374e89a7178913f74`:

- `cargo test -p buzz-core` — 246 unit + 2 doc tests passed
- `cargo test -p buzz-relay
private_managed_agent_kind_remains_rejected_until_atomic_ingest_exists`
— passed
- push hooks: Rust tests and desktop checks passed (`2145` desktop tests
passed, `14` ignored)
- `cargo fmt --all -- --check`
- `git diff --check`

## Review

Princess Donut cleared security/data integrity with no remaining
high/medium findings. Mongo cleared migration compatibility and wire
grammar. The later runtime lease/fencing protocol was also adversarially
cleared as a plan; implementation slices still require independent
evidence before activation.

Deterministic plaintext/signed-projection/auth-tag interoperability
vectors remain a valuable follow-up, not an S0 merge gate; random NIP-44
ciphertext is intentionally not snapshotted.

dc17965c79 fix(mobile): serialize channel sections sync (#3165)
### What changed?

Serializes channel-section relay synchronization so a late relay
`CLOSED` cannot overlap an in-flight retry and install duplicate
subscriptions. Pending subscription results are invalidated and
immediately closed when the manager is disposed or superseded.

### Why?

The startup retry added in #3004 could race with a late `CLOSED` or
manager disposal, leaking an untracked live subscription. This keeps
retry recovery single-flight and makes the lifecycle boundary explicit.

### How is it tested?

Build and run.

Added tests:

-
[`ChannelSectionsManager`](https://github.com/block/buzz/tree/main/mobile/test/features/channels/channel_sections/channel_sections_manager_test.dart)
interleaving coverage for in-flight retry serialization and disposal
during subscription setup

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.

4a2305170e fix: reauthenticate databricks model discovery (#4008)
## Summary
- preserve Databricks catalog 401 responses as authentication failures
and retry discovery exactly once after silently refreshing the rejected
bearer
- preserve runtime OAuth recovery: when discovery has no usable OAuth
credential, `session/new` succeeds with only the trimmed configured
model so the first `session/prompt` can run the existing browser PKCE
flow
- reject a rejected configured `DATABRICKS_TOKEN` with actionable,
non-interactive guidance; static credentials cannot recover through PKCE
- use the configured-model fallback for non-auth discovery failures
without caching failed or fallback catalogs, so later sessions retry
discovery
- keep known Databricks v2 models only for authenticated empty-catalog
responses and mark their provenance
- resolve discovery before MCP spawn or session registration, preventing
failed discovery from leaking resources or consuming session capacity
- permit serialized interactive PKCE only from the explicit saved-agent
model picker; passive draft discovery never opens a browser

## Runtime flow
1. OAuth discovery attempts cached credentials and silent refresh
without opening a browser.
2. If no usable OAuth bearer exists, `session/new` advertises only the
configured model and succeeds.
3. The first `session/prompt` uses `TokenSource::bearer()`, which may
launch browser PKCE.
4. A later session retries discovery and caches only the authenticated
catalog.

## Regression coverage
- rejected-but-locally-fresh OAuth bearer performs one refresh and one
catalog retry
- OAuth mode with no cached token allows `session/new` and returns
exactly the trimmed configured model
- the OAuth fallback is not cached; a later authenticated session
retries discovery and caches the returned catalog
- rejected static tokens still reject `session/new`
- failed discovery does not consume the sole session slot or spawn the
supplied MCP process
- Desktop interactive/passive auth intent, static-token redaction, and
authenticated empty-catalog provenance

## Verification
- `cargo test -p buzz-agent`
- `cargo test --manifest-path desktop/src-tauri/Cargo.toml --lib
commands::agent_models`
- `cargo clippy --manifest-path desktop/src-tauri/Cargo.toml
--all-targets -- -D warnings`
- `cargo fmt --all -- --check`
- `git diff --check`
- full pre-push hooks

## Review
Adversarial review found and drove fixes for session/MCP resource
leakage, duplicate concurrent PKCE flows, sensitive error propagation,
incorrect 403 reauthentication, missing discovery-level coverage,
passive browser launch, and the Desktop file-size ratchet. The final
follow-up preserves the existing prompt-time OAuth flow while retaining
static-token rejection and pre-allocation discovery ordering.

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

4c665aeac3 fix(desktop): serialize tray channel actions for frontend (#4762)
## Summary
- serialize native `openChannel` tray actions with the camelCase field
names consumed by the TypeScript frontend
- prevent a valid tray channel ID from becoming `/channels/undefined`
- add a Rust serialization contract test covering the complete frontend
payload shape


### Root cause
`TrayAction` renamed the enum variant to `openChannel`, but its struct
fields still serialized as `channel_id` and `community_generation`. The
frontend reads `action.channelId`, so tray navigation called
`goChannel(undefined)`.


### Testing
- manually verified the corrected runtime payload and tray navigation
before removing temporary logging
- `just desktop-ci`
- pre-push hooks (desktop checks/tests, Tauri checks, and Rust tests)

- **Reviewed candidate:** `ac589061ef1009f55384536e483cfe9b1260697b`
- **Previous desktop release:** `desktop-v0.5.4`
- **Proposed immutable tag:** `desktop-v0.5.5`

This PR must be **squash merged** only after the Desktop Release
Candidate check passes. The branch must remain based directly on current
`main`; stale base, payload drift, incomplete notes, or an unauthorized
merge produce no tag.

The checked-in changelog accounts for every non-merge commit in the
release range. Publication remains bound to the immutable candidate tag.

e30db7028f feat(projects): support multiple repositories (#4671)
## Summary
- adopt the finalized NIP-MP project model so one project can enumerate
and switch between multiple NIP-34 repositories
- add project and repository navigation, activity summaries,
existing-repository attachment, and repository access-channel management
- preserve privacy-safe activation provenance for agent-authored
patches, pull requests, issues, and associated commits

## Test plan
- [x] Run desktop typecheck and unit tests
- [x] Run focused NIP-MP, repository access, and provenance tests
- [x] Run Rust formatting and desktop lint checks
- [x] Run the complete pre-push suite after merging current `main`
- [ ] Manually verify project creation, repository attachment,
switching, and access repair on staging
- [ ] Manually verify public-channel and private-agent origin labels on
newly created Git activity

383d9e1eaf fix(ci): make desktop cache test version agnostic (#4791)
## Summary

- derive the current desktop package version in the release cache-key
contract test
- mutate that version in both `Cargo.toml` and `Cargo.lock` instead of
assuming `0.5.4`
- prevent desktop release version bumps from failing generic CI

## Context

PR #4788 bumped Desktop to `0.5.5`, exposing the hard-coded fixture. The
dedicated release candidate check passed, while generic CI failed with
`desktop version changed cache key`.

## Verification

- pre-commit hooks passed
- pre-push hooks passed
- CI will validate the full contract

7bcfe7e0a1 fix(desktop): widen post-Enter timeouts in empty-edit-delete spec (#4792)
## Summary

Increases three Playwright assertion timeouts in
`tests/e2e/empty-edit-delete.spec.ts` from 5s to 10s to fix a
shard-composition flake introduced by PR #4694.

## Root Cause

PR #4694 added `huddle-transcription.spec.ts` (477 lines, 22+ tests) to
the Desktop Smoke E2E suite, shifting shard 2 composition so that
`empty-edit-delete` now runs with significantly more accumulated browser
state. The three affected assertions all wait for a React state update
triggered by pressing Enter in edit mode:

- `alertdialog` becoming visible after an empty edit (tests 1 and 2)
- `edit-target` hiding after a successful non-empty edit (test 3)

These transitions go through the React scheduler. In isolation they
complete in milliseconds. In a loaded headless shard with accumulated GC
pressure, the 5s window became insufficient — test 3 failed 3/3 times in
CI run
[30946444168](https://github.com/block/buzz/actions/runs/30946444168)
with `edit-target` still visible after Enter.

No product code is changed. The empty-edit-delete flow is correct and
untouched by #4694. This is a test-environment timing adjustment only.

## What Changed

- `tests/e2e/empty-edit-delete.spec.ts` — three `{ timeout: 5_000 }` →
`{ timeout: 10_000 }` for the post-Enter React-update waits

## Validation

- `just desktop-check` — passed
- `just desktop-test` — 4194 passed, 0 failed

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.
