44316ff72f feat(mesh): upgrade to mesh-llm 0.76.0-rc8 and recommend Qwen3.8 27B (#6189)
Upgrades Buzz's mesh-llm dependencies through the released `v0.76.0-rc8`
tag (`2040765d`), including the Qwen3.8 curated recommendation and rc8's
scheduler/runtime improvements.

**Scope note:** the earlier open-relay/unenforced-admission mode has
been removed from this PR at Mic's direction — it is not a product mode
we want. Mesh admission remains roster/allowlist driven, exactly as on
`main`: on a relay with no NIP-43 membership snapshot the mesh runs
self-only. No NIP-11 mode probing, no mode-transition restarts. A future
perimeter/admission strategy for open relays will be designed
separately.

This PR also:
- seeds `BUZZ_AGENT_LLM_TIMEOUT_SECS=660` for mesh agents, above
MeshLLM's 600-second backend timeout;
- makes `desktop-tauri-clippy` lint both default and `mesh-llm` cfg
graphs;
- runs the feature-enabled desktop test suite in CI;
- recommends Qwen3.8 27B Q4_K_M for 64 GB-and-larger machines, then
ladders down through Gemma 4 E4B and Qwen 9B for smaller machines;
- keeps stored shared-compute `auto` translated to MeshLLM's supported
wire model `mesh`.

RC8 verification:
- `just ci` passed locally at
`92ecc7ec933bdd4df804cc9f28a2b51efa5313c5`.
- Pre-push differential gates passed, including both desktop Tauri cfg
graphs and package tests.
- A prior isolated runtime smoke used the RC8 binary's OpenAI endpoint
for a Buzz-shaped system/user/tool/tool-result/final-response loop; all
assertions passed and the isolated process was shut down.

Perf previously measured on M5 Metal, Qwen3.8-27B-Q4_K_M: TTFT 0.22–0.32
s, ~25 tok/s streaming; agent-shaped turns ~1 s to first token after the
first (prefix cache).

cd54e26823 fix(agent): route GPT-5+ model-service FQNs to Responses (#7358)
## Summary
Route Databricks Unity Catalog model services to OpenAI Responses when
their service name matches GPT-5 or newer. These models can reject tools
plus reasoning on Chat Completions.

Match only the service component, using the existing family-token
boundaries and a numeric major version. Catalog and schema names cannot
select the protocol. Keep neutral effort capabilities and the full model
ID unchanged; other services still use MLflow Chat Completions.

Keep the Rust and desktop resolvers in sync, add shared boundary cases
and a captured-HTTP regression for completion and summarization, and
update the documented FQN rule.

### Related issue
No duplicate found in searches for “FQN responses” PRs or “astra”
issues. Related: #6918 introduced Unity Catalog discovery.

Originating conversation:
buzz://message?channel=0b881928-a3a6-4c01-b981-8e64268f01ce&id=770949343bc96a9ed88acd90a1b37d358a0efc52c79237d0fdb491ce02b8d4ed

### Testing
No live Databricks inference test. The gateway must accept the full
model-service ID on its OpenAI Responses route; this remains the
integration risk.

The local `just ci` attempt exceeded its five-minute deadline during
`mobile-check`, so the full repository gate was not completed. All
push-hook checks passed.

3c7f288c60 chore(release): release Buzz Desktop version 0.5.23 (#7381)
## Buzz Desktop release v0.5.23

- **Frozen main:** `dad5a33865fc81a2e55b3b60746632f615ec1e3a`
- **Reviewed candidate:** `b9392d9d78744df365f9276e1ffe8c1baa5ea903`
- **Previous desktop release:** `desktop-v0.5.22`
- **Proposed immutable tag:** `desktop-v0.5.23`

This PR may be **squash merged** after the Desktop Release Candidate
check and all protected-branch checks pass. Merging authorizes
publication of the exact reviewed candidate; later or unrelated changes
on `main` cannot alter it.

The checked-in changelog accounts for every non-merge commit in the
release range. The Desktop tag points to the reviewed candidate commit,
not the later squash commit. Publication remains bound to that immutable
candidate tag.

dad5a33865 fix(desktop): keep packaged frontendDist relative so Windows embeds assets (#7177)
## Root cause

`tauri-command.mjs` points `frontendDist` at a `mkdtemp` directory so
concurrent OSS/internal packages cannot overwrite each other's assets.
On Windows that is an absolute path with a drive letter.

`FrontendDist` is an untagged serde enum whose **first** variant is
`Url(Url)`, and `C:\Users\...` is a valid WHATWG URL with scheme `c:`,
so serde selects `Url`. `tauri-codegen` then does:

    FrontendDist::Url(_url) => Default::default(),   // embed nothing

A missing *directory* panics with a clear message; a URL is silent. The
build exits 0 and produces an installable app with no frontend assets,
which boots to `ERR_FILE_NOT_FOUND` in the WebView.

Linux and macOS are unaffected — `/tmp/...` has no scheme, so it falls
through to `Directory`.

This affects every Windows build that goes through `pnpm tauri build`,
including `release.yml`'s NSIS job and `windows-canary.yml`.

## Fix

Pass the path relative to the config's own directory. `tauri-codegen`
resolves `frontendDist` with `config_parent.join(path)`, so a relative
path reaches the same directory and cannot parse as a URL. When the temp
directory is on another drive there is no relative form, so the scratch
root is created beside the config instead.

`BUZZ_PROTECTED_BUILD_OUTPUT` still receives the absolute path, and
cleanup is unchanged.

## Testing

`tauriCommand.test.mjs` asserted against the value it had just been
handed, so it could not observe this. Its fake CLI also resolved
`frontendDist` against the process cwd, which is not what Tauri does.

- Fake CLI now resolves against the config directory, matching
`config_parent.join(path)`.
- New case asserts the packaged `frontendDist` is not absolute and does
not parse as a URL. The absolute check is what fails on Linux/macOS, so
the regression stays covered on every platform.
- Verified the new case fails on the unpatched wrapper and passes with
the fix; the two existing cases pass either way.
- Desktop suite: 5844 passed. `useDocumentVisible` has a pre-existing
load-dependent flake that also reproduces on an unmodified checkout.
- Biome check clean on both files.

Verified end to end by rebuilding the Windows NSIS installer: embedded
asset keys in `buzz-desktop.exe` went from 0 to 490, and the app
launches.

f038cbbb0d fix(sidebar): simplify unread indicators and emphasize priority activity (#7134)
**Category:** fix
**User Impact:** The sidebar now presents unread activity consistently:
unread rooms are bold, offscreen activity is counted by destination, and
DMs or directed activity receive stronger emphasis.

**Problem:** Sidebar unread state was split across competing signals:
agent work could trigger overflow, message totals inflated its count,
non-DM rows showed redundant numerals, and routine room activity looked
as urgent as DMs or directed messages. This made the sidebar noisy and
made the overflow value harder to interpret.

**Solution:** Use one stable offscreen unread control that counts rooms
and DMs—not messages—and remove agent work from that signal. Keep
ordinary room activity quiet; promote DMs, mentions, broadcasts, and
relevant thread replies; preserve DM avatars and targeting; bold every
unread room; and retain thread dots while removing non-DM numerals.

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

**desktop/src-tauri/src/unread_catch_up.rs**
Classifies relevant thread replies as priority activity during native
unread catch-up so startup state matches live rendering.

**desktop/src/app/AppShell.tsx**
Passes the priority unread destination set into the sidebar.

**desktop/src/features/channels/useUnreadChannels.ts**
Projects unread destinations, priority state, and thread replies
consistently while keeping Dock badge behavior separate from sidebar
emphasis.


**desktop/src/features/sidebar/lib/useOffscreenActivityChannelIds.test.mjs**
Removes tests for the superseded agent/activity overflow projection.

**desktop/src/features/sidebar/lib/useOffscreenActivityChannelIds.ts**
Removes the old agent-plus-message overflow projection so agent work
alone no longer creates the unread indicator.

**desktop/src/features/sidebar/lib/useSidebarActivityOverflow.ts**
Replaces activity-volume overflow state with unread-destination overflow
state.

**desktop/src/features/sidebar/lib/useSidebarUnreadOverflow.test.mjs**
Covers priority detection and destination-count labels for the new
overflow projection.

**desktop/src/features/sidebar/lib/useSidebarUnreadOverflow.ts**
Counts distinct offscreen unread destinations and determines quiet
versus primary treatment per direction.

**desktop/src/features/sidebar/ui/AppSidebar.tsx**
Renders one stable overflow control, preserves protected-DM visibility
filtering, and prioritizes visible unread DMs for previews and
navigation.

**desktop/src/features/sidebar/ui/AppSidebar.types.ts**
Adds the priority unread destination set to the sidebar contract.

**desktop/src/features/sidebar/ui/CustomChannelSection.tsx**
Stops forwarding non-DM unread counts into custom channel rows.

**desktop/src/features/sidebar/ui/MoreUnreadButton.test.mjs**
Updates control coverage for explicit emphasis, destination labels, and
DM targeting.

**desktop/src/features/sidebar/ui/MoreUnreadButton.tsx**
Applies quiet or primary treatment without changing geometry,
accessibility text, DM avatars, or click behavior.

**desktop/src/features/sidebar/ui/SidebarSection.tsx**
Removes non-DM row numerals while retaining unread weight and thread
preview affordances.

**desktop/src/shared/ui/UnreadPill.tsx**
Shares one composition between quiet and primary states so only color
treatment changes.

**desktop/tests/e2e/badge.spec.ts**
Covers destination counting, promotion without count inflation,
DM/thread priority, row bolding, and removed numerals; also captures the
reviewed UI states.

**desktop/tests/e2e/channel-activity-popover.spec.ts**
Updates channel activity assertions for the numeral-free row treatment.

**desktop/tests/e2e/channels.spec.ts**
Updates channel unread expectations to use bold text rather than a row
count.

**desktop/tests/e2e/thread-unread.spec.ts**
Keeps thread unread-dot and popover coverage while asserting the room
itself is bold.

</details>

## Reproduction steps

1. Open a workspace with enough sidebar destinations to scroll rooms
above or below the viewport.
2. Receive ordinary unread activity in an offscreen room; verify one
quiet `N unread` indicator appears and counts the room once regardless
of message volume.
3. Receive a mention, broadcast, or relevant thread reply in an
offscreen room; verify the same count becomes primary without changing
its geometry or adding a badge.
4. Receive an unread DM, including thread-only activity; verify the
indicator is primary, shows the DM avatar when available, and navigates
to that DM.
5. Scroll the destination onscreen or mark it read; verify the count and
treatment update from the remaining offscreen destinations.
6. Inspect unread non-DM rows; verify their names are bold, numeric
badges are absent, and thread dots still open the unread-thread preview.

## Screenshots

### Ordinary unread room
Routine offscreen room activity uses the quiet treatment.

### Directed unread activity
The same destination count becomes primary when an offscreen room has
directed activity; geometry and label remain unchanged.

### Thread-only unread DM

unread activity.

4beffef697 feat(buzz-acp): update base prompt; add buzz context and skills to Pi agents (#7335)
## Summary

- launch Pi through a private Buzz wrapper so managed Pi agents receive
Buzz's base prompt plus the configured thread/channel session model via
`--system-prompt`
- load the Buzz workspace skill directory with Pi's repeatable `--skill`
flag, making `~/.buzz/.agents/skills/buzz-cli` available alongside Pi's
normal global skill discovery
- report Pi and `pi-acp` installation states separately so setup
guidance points to the missing component

`pi-acp` does not currently consume the ACP `session/new` system prompt,
but its normal new-session and restore paths do honor
`PI_ACP_PI_COMMAND` as the executable used to launch Pi. Buzz reserves
that variable and sets it to a private generated launcher. The launcher
invokes `pi` from Buzz's effective `PATH`, adds `--system-prompt <file>`
and `--skill <workspace>/.agents/skills`, and forwards `pi-acp`'s RPC
and session arguments unchanged. This keeps the integration entirely in
`block/buzz`, without changes to Pi or `pi-acp`.

### How PI_ACP_PI_COMMAND works in `pi-acp`

`PI_ACP_PI_COMMAND` selects one executable; it does not accept
arguments. Therefore:

```bash
# Does not work
PI_ACP_PI_COMMAND="pi --skill ~/.buzz/.agents/skills"
```

Buzz does not expose this variable as user configuration. It creates a
private launcher and sets `PI_ACP_PI_COMMAND` only on the `pi-acp`
child. Conceptually, that launcher executes:

```sh
#!/bin/sh
exec pi \
  --system-prompt "$PRIVATE_SYSTEM_PROMPT" \
  --skill "$HOME/.buzz/.agents/skills" \
  "$@"
```

### Related issue

Follow-up to #7208. No duplicate issue or open PR found.

### Testing

- `just ci`
- `cargo test -p buzz-acp pi_launcher`
- `cargo test --manifest-path desktop/src-tauri/Cargo.toml
managed_agents::env_vars::tests`
- `cargo test --manifest-path desktop/src-tauri/Cargo.toml
managed_agents::discovery::presets::tests`
- pre-push branch checks

No screenshots: the UI change is state-dependent setup guidance only.

---
**Update Sep 4, 13:35:** Made `PI_ACP_PI_COMMAND` entirely Buzz-owned.
- Managed agent configuration now rejects the variable as a user
override.
- Buzz always launches `pi` from its effective `PATH` and rejects
inherited values before creating its private launcher.
- Removed the custom Pi executable discovery path and its internal
environment alias.

---
**Update Sep 4, 14:03:** Reject inherited `PI_ACP_PI_COMMAND` values
instead of replacing them.
- Pi startup now fails with an actionable message telling the user to
unset the variable.
- Removed the Pi-specific exception from the generic ACP environment
injection path.

4afef8649a fix(desktop): restore mention chip identity icons (#7338)
## Summary

Restore the missing **@ glyph for people and robot icon for agents**
after #7133, and incorporate the requested compact public-key display.

- Wrapping mention chips render their existing bounded icon-bearing
leading fragment.
- Readonly chips show bound keys using the same `8 leading…4 trailing`
formatter as the channel member list: `Scout (150b20bd…15dc)`.
- Full literal labels and exact keys remain authoritative in metadata,
profile targets, title/accessible-name attributes, editor text, saved
bodies and recipient tags. Display abbreviations are never used for
recipient lookup.
- Copy/paste restores the full literal label for a complete compact
chip; partial selections remain plain text. Two keys sharing the same
abbreviation still round-trip to their separate exact recipients.
- No recipient-resolution, authorization, wire-format, composer, or CSS
changes. Existing labels, icons, cloud markers and ordinary mentions
remain intact.

## Verification

Published candidate `9365ab9bc9d9c5d10802580cd576f8e378ff492f`, based on
main `e09f715c9d0ee2cb7bf8a39061e601f3a502f588`:

- **6,444 desktop unit tests passed** on this candidate's final source
tree.
- **44 mock-Chromium tests passed, zero retries in the final run**
across mention recipients, clipboard and cloud provenance: exact
recipient selection, ambiguity rejection, send/edit/reopen, forwarding,
full/partial copy, mismatched-key rejection, matching-abbreviation
collisions and 100%/150% narrow-window geometry.
- TypeScript, desktop Biome/check guards, protected-feature production
build and E2E build passed.
- The compact-renderer regression fails with the formatting call
removed. Original missing-icon and hidden-text accessibility regressions
have red/green evidence.
- Fresh self-review traced rendering, full-key metadata, copy
classifier, paste normalization and identity trust. The same display
formatter owns the accepted compact form on both clipboard sides.

Iteration exposed an existing team-insertion separator flake (passed
final full run) and two new fixture assumptions: non-member sends
require invitation, and Chromium rich paste may retain an NBSP
separator. Tests now exercise invitation and normalize only that
separator when comparing the captured full body and exact tags; no
product change was needed for either.

Earlier local repository-wide `just ci` completed in two invocations
because its initial call hit the ten-minute tool limit during Tauri
compilation. Unchanged native/mobile/backend evidence is reused; the
desktop delta received the full checks above and new remote CI. Native
VoiceOver, real Tauri selection, dark theme and non-Chromium observation
were not performed. Browser artifacts exercise real frontend with mocked
Tauri/relay boundaries, not an installed release.

## Review and visual evidence

Current-head CI and automated review must complete after this update;
the old `2997bfb5` green results do not establish this new head.
Required human review remains separate from agent approvals. No
merge/install/restart authorization.

Before/after icon evidence:
https://github.com/block/buzz/pull/7338#issuecomment-5544575866

Updated compact-key screenshots are posted below. The editor
intentionally retains the full literal address; only readonly chip
display is abbreviated.

e7e29937a1 feat(desktop): invite owned agents from standalone forums (#7125)
## Summary

In Desktop's standalone Forums, selecting an owned agent from another
device could leave a post or reply unsendable if the agent had not
joined the forum. This adds **Invite / Cancel** to the send flow so you
can resolve membership without leaving your draft.

- **Invite** checks response policy and your permission to add members,
adds the agent to the forum, waits for refreshed membership, then
rechecks authorization before posting to the original destination.
Membership is forum-wide, not limited to one post.
- **Cancel / Escape** keeps the text, attachments and selected
recipients for retry. Unlike chat's **Do nothing / Send anyway**, this
dialog has no reference-only send choice. Invite is disabled while
pending; Cancel remains available.
- Leaving the source post/reply cancels its pending invitation, even if
you return. Errors remain visible, focus returns to the initiating
editor when appropriate, and late completion cannot resume a cancelled
post or interfere with a newer attempt.
- A rejected send restores text, uploaded media and exact selected
recipients to the source draft only if no newer edit, deletion, upload
intent or send supersedes it. Clipboard verification settles before
recipient capture, with stale edits/navigation fenced out.

### Related issue

Targets `main` after #7124 merged. This PR reuses its publication checks
and draft protection; the five forum commits have been replayed
unchanged onto the merged parent. Owned-agent discovery (#7122) is
already merged. Split from #7114.

Forum creation/templates, channel-less Notes and local-agent management
are unchanged. Duplicate-name binding from #7133 is already merged and
retained by this stack. Inviting does not start a remote agent or
promise that it is online or will reply.

### Testing

Forum composer lifecycle tests, including clipboard-settlement cases,
and TypeScript/changed-file formatting checks passed after the restack.
Earlier invitation, focus and transport-recovery browser coverage is
retained, not claimed as a fresh full browser run on this head. See
[live CI](https://github.com/block/buzz/pull/7125/checks) for
current-head results. Browser evidence uses mock IPC; no full local
`just ci` pass or native/live-relay validation is claimed.

To try it: open a forum post or reply, select an owned nonmember agent
and send. Cancel, then retry without reselecting; Invite should add that
agent before posting. Deny the add to check the visible error and
retained draft. Navigate away/back during a pending invitation or
rejected send; no stale publication or overwrite of a newer draft should
occur.

![Forum invitation with Invite and
Cancel](https://raw.githubusercontent.com/block/buzz/6481bd088d661975672addcc834231df6ac88705/pr-7125--forum-invite.png)

*Earlier mock-browser capture, not current-head runtime proof. [Error
and successful-post
captures](https://github.com/block/buzz/pull/7125#issuecomment-5513883462);
no before-state/native capture available.*

**Limits:** cancellation cannot undo accepted membership changes or
dispatched posts; authorization and publication are not atomic. Recovery
is same-window, subject to browser storage limits, and is not a durable
in-flight send journal: reload/crash can lose a pending snapshot.
Cross-window coordination and in-flight upload custody are unchanged.
The parent's legacy member-agent compatibility does not establish
ownership for nonmember invitations.

d595806fc3 fix(desktop): authorize remote mentions at publication (#7124)
🤖

## Summary

In Buzz Desktop, you could own an agent running on another device but be
unable to mention it in a channel where it had not yet joined: it was
filtered out before you could invite it. A selected agent could also
disappear from the message's recipients when permissions changed. This
lets you select an eligible agent in the existing **@ menu**, invite it
from the message composer, and send to that agent—or see an error and
keep your draft rather than silently sending without it.

#### Where the experience changes

| Screen / control | Before → after |
| --- | --- |
| A channel's **Message #…** composer, or a message's **Reply in thread
to …** composer | Type `@` (or use the existing @ button), choose your
agent, write the message and press **Send message**. An owned agent not
yet in the channel can now reach the existing **“Mention people outside
this channel?”** dialog when its response settings allow you to address
it. |
| That dialog's **Invite** button | Previously the membership
requirement could block the agent before the invitation. Now Invite
checks permission to add it, adds it as an agent member of the
**channel** (not just the thread), then rechecks membership and response
permission before sending the waiting message. An agent already in the
channel needs no invitation. |
| Existing direct message, or the new-message screen with the **To:**
field | A mention is checked against the conversation the message will
actually enter, including a newly created direct message, rather than
the old or not-yet-created destination. This does not add an Invite
control to direct messages. |
| Editing a message / sending attachments | The selected agent remains
part of the send or edit attempt through attachment upload and the final
permission check. Lost permission produces a visible error instead of
dropping that recipient. |

**Invite is not the only chat choice.** The existing **Do nothing**
button sends the message *without inviting or notifying the nonmembers*;
their names remain references in the text. Where you cannot invite, that
choice is labelled **Send anyway**. To abandon the send instead, dismiss
the dialog with Escape. Invitation actions are disabled while
preparation is pending, preventing duplicate clicks.

**Leaving and returning must not resurrect a cancelled send.** Switching
threads or leaving the composer cancels its pending invitation, even if
you return to the same thread. Cancellation before dispatch sends no
message; an accepted membership change cannot be automatically undone.
An ordinary send without a pending invitation remains bound to its
original destination rather than following you into another
conversation.

**Failed sends must not overwrite your next draft.** If you leave a
thread, return and replace or deliberately clear its draft while an
older send is pending, the older failure cannot restore deleted text,
recipients or files; success cannot erase the newer draft—even if its
text is identical. An untouched draft cleared automatically for sending
remains recoverable on failure. This protection also covers reopening
the composer and starting a newer send.

The channel timeline also keeps its existing **new-messages / Jump to
latest** button available when newer messages are waiting to be
displayed. For example, after sharing a reply to the channel and closing
the thread panel, you can click the catch-up button to reveal buffered
messages. Closing the thread does **not** guarantee the shared row
appears automatically or force you away from reading history.

### Related issue

Built on [#7122](https://github.com/block/buzz/pull/7122), base branch
`split/owned-agent-discovery`, which lets Desktop find and verify owned
agents independently of this device. Current integration head:
`1144465d00273cf74b7c22544ae5a3299bd98560`, built on exact published
root `3a56d17824522580fe04cae463b54f4c7ba66021`. Root #7122 has its own
CI and security gates; this PR must not land ahead of that dependency.
Finding an agent is not channel membership, online status or a promise
of a reply. This PR changes what the existing message controls can do
with those agents; it adds no profile, presence, cloud marker or remote
start/stop UI.

Standalone forum post/reply **Invite / Cancel** is added separately in
[#7125](https://github.com/block/buzz/pull/7125); here those composers
only gain visible authorization errors. Same-name selection/binding
fixes ([#7133](https://github.com/block/buzz/pull/7133)) and mention
spacing ([#7128](https://github.com/block/buzz/pull/7128)) are not
included.

These show the relevant UI, not live agent availability, native

before-state screenshot is available.

Existing coverage exercises exact recipients, invitation
rejection/cancellation, new direct-message destinations, uploads, edits,
thread re-entry and stored-draft deletion. The timeline regression
checks the shared reply becomes visible using the available catch-up
action.

**Integration validation (2026-09-02):** independently reviewed the
routing delta onto root `3a56d178`: seven original patches unchanged;
two reconciliations retain generic publication-error toasts alongside
authorization errors and retain non-authored editability updates. Added
two production-hook regression tests (normal and queued-media
publication) requiring visible generic error, recovered draft and
released pending state.

- Writer validation: **5,995 Desktop tests**, **42 focused tests**, **22
mock-IPC browser journeys** (18 routing, 2 root provenance, 2
destination binding), and **1 voice-note failure journey** passed; lint,
types, size guards and E2E build also passed.
- The broad suite ran before the final formatting-only test amendment,
not as an exact-final-head rerun. Independent AST comparison confirmed
that amendment is semantics-preserving; **4 fresh assertions at final
`1144465d`** passed. Publication rechecked final-head TypeScript,
amended-test formatting and `git diff --check` successfully. No new full
repository `just ci` run is claimed.
- Browser tests use an isolated E2E build and **mock IPC**, not live
relay/native authorization. Historical screenshots above are explicitly
earlier UI evidence, not exact-head runtime certification. Packaged
Tauri/live-relay behavior was not independently witnessed.
- **Published-head gates:** [current CI
run](https://github.com/block/buzz/actions/runs/33657948560) and
[renewed exact-head formal review
request](https://github.com/block/buzz/pull/7124#issuecomment-5513218340)
must clear before landing. [Earlier CI
run](https://github.com/block/buzz/actions/runs/33438436438) and the two
earlier approvals cover `7ffead0f`, not this new head. Root CI/security
clearance remains separate; the independent scoped integration approval
is not merge authorization.

To try it: in a channel or thread, select an owned nonmember agent,
Send, then Invite or Escape and retry. Deny the add or revoke its
response permission before sending: expect a visible error and
recoverable draft, not a message missing the agent. During a pending
send, return to the source thread, edit or clear the draft, then leave
again: late completion must not overwrite that choice.

**Limits:** permission checks and sending are separate operations;
cancellation cannot retract a dispatched message. Draft protection is
same-window, not new cross-window deletion synchronization. Standalone
forum transport failure can still restore text/media without the exact
selected recipients. Native compatibility is inherited: open-source
builds may still recognize a valid legacy, self-declared agent already
in the channel when verified ownership is absent or rejected; that does
not establish ownership or unlock this owned-nonmember invitation path.
Invalid policy from a verified owner is still rejected. No agent
response is guaranteed.

`system` is confusing (esp with system role) and agent instructions is
what shows up in the UI today

ee883d73fb fix(desktop): bind duplicate mention selections to exact recipients (#7133)
## Summary

Selecting two people or agents named Scout could replace the first
recipient with the second even though the message still looked right.
This binds each selection to its exact identity: the first keeps
`@Scout`, and a conflicting selection gets `@Scout (<full public key>)`.
Removing one no longer removes or redirects the other.

- Reuse the existing **@ suggestion list**; team selection and automatic
agent addressing reserve and reuse distinct labels too. Typing an
ambiguous name manually shows an instruction to use the picker and
preserves the draft without publishing—in chat, edits and standalone
forums.
- Share literal mention matching across recipient extraction, removal,
display and editing so a shorter name cannot claim another recipient's
longer or qualified label.
- Rebuild authored references when a message is edited, and use the
latest authorized snapshot when reopening or forwarding.
Rendering/editing can recover qualified identities only from the
message's recorded references, not from a key typed into its body.
Unresolvable historical names remain literal rather than guessed
recipients.
- Wrap full-key labels within narrow/zoomed layouts while keeping their
complete accessible label and ordinary mention icons. Edit activation
waits for the action menu's focus cleanup before focusing the editor.

### Related issue

Targets `main`; mention spacing (#7128) is already merged. Split from
#7114. This is independent of the #7124 → #7125 remote-invitation stack
and does not expand agent eligibility or invitation permissions. The
separate Enter-selection suffix issue remains tracked in #7253.

### Testing

The desktop unit suite and focused mock-Chromium checks passed on the
published integration candidate, including pending-paste selection,
edit/forwarding, copy and narrow-layout cases; formatting, types and
frontend builds passed. On `0b3b18c0`, 64 focused trust/paste/selection
unit tests and six mock-Chromium tests passed with zero browser retries,
including actual timeline chip copy → fresh channel paste → send and
mismatched-key rejection; TypeScript, changed-file Biome and an isolated
E2E build passed. The broader browser run had copy failures before the
focused repairs and is not claimed as wholly green. See [live
CI](https://github.com/block/buzz/pull/7133/checks) for current-head
results. No full local `just ci` pass, native/live-relay or
cross-browser validation is claimed.

To try it: select two same-name recipients, remove one, send, then
edit/reopen and forward; only the intended identities should remain.
Type an ambiguous name without choosing a suggestion and check that
sending retains the draft with an error. Inspect full-key labels in a
narrow window at 150% text size, and open Edit and type immediately.

![Ambiguous mention keeps the chat
draft](https://raw.githubusercontent.com/block/buzz/c48053209b36b3b1bf7197cf2d606d27b48a27c0/pr-7133--ambiguous-general.png)

![Full-key label in a narrow, zoomed

*Earlier mock-browser captures, not current-head runtime proof. No new
before-state capture; screenshots alone do not prove recipient
delivery.*

**Clipboard trust:** generated full-key-qualified mentions now retain
their exact recipient after copy/paste when the full key matches the
clipboard record and community directory/profile state independently
vouches for the base alias, including numeric collision suffixes. A
qualifier alone does not establish trust. Arbitrary historical labels
still cannot always be reconstructed.

b1f6b7ef77 feat(desktop): preserve mentions across copy and paste (#7228)
Copying a message out of the timeline lost the mention. The rendered
chip drops
the `@` for display, so the clipboard carried "John Smith" — two
ordinary words
no composer could bind back to a pubkey. Pasting into another channel
produced
dead text, and sending it tagged nobody.

## What changed

Every Buzz copy now writes two clipboard flavors in one transaction:

- **`text/plain`** — readable anywhere, sigils restored, no pubkeys.
This is what
  TextEdit, Slack, and every other external app receive.
- **`text/html`** — the same content with each mention wrapped in a span
carrying
  `data-mention-pubkey` / `-label` / `-kind`.

On paste, the composer harvests those records, registers each `name →
pubkey`
with the existing mention machinery, and inserts the content: the chip
re-lights
and the send path recovers the identity the author tagged. A marker
attribute
records what the plain flavor holds, so a Markdown copy pastes through
the text
pipeline and a rendered copy through the HTML one.

**Covered surfaces:** timeline selection copy, thread-panel selection
copy,
forum post/reply selection copy, "Copy message", and composer copy/cut —
plus
paste in both the channel and forum composers.

## Trust boundary

Clipboard HTML is untrusted, and the branch treats it that way:

- Records are capped (50), labels bounded (200 chars), and a pubkey must
be
  64 hex before it can become a `p` tag.
- **Only mentions the paste actually shows are registered.** An empty
`<span data-mention-pubkey=… -label="Jane Doe">` would otherwise rebind
that
display name for the rest of the composer session, so a later
hand-written
@Jane Doe would chip-light convincingly against the attacker's key. Each
  branch registers only the records whose label appears in the text *it*
inserts, matched with `getMentionOffsets` — the same matcher the
send-time
  extractor uses.
- **The visibility gate reads only what ProseMirror will insert.**
`DOMParser` hard-drops `script`, `style`, `title`, `noscript`, `object`,
and
`head` content, so `visible<style>@Jane Doe</style>` beside an empty
chip span
used to smuggle a binding past the gate. Those elements are stripped
before
  either output is derived.
- **A partial chip never gains a sigil.** A selection crossing a chip
boundary
falls through to the browser's default copy, which serializes the full
identity
attributes around a slice of the text — pasting that invented "@Smith"
out of
"John Smith". Paste now leaves a fragment as plain text, tolerating only
what a
whole chip picks up in transit (restored sigil, author casing, U+00A0
swaps,
  and the label cap's own ellipsis).

Both clipboard sides share one `matchChipTextToLabel` helper, in the
module that
owns the label attributes, so copy and paste cannot drift on what counts
as a
whole chip.

## Notes

- Mention matching reuses `getMentionOffsets`, so code spans and fences
are
  excluded and the longest display name wins.
- The plain flavor inlines chip boxes before reading `innerText`; a chip
is a
flex container, so the browser's own copy split "@John Smith" onto its
own line.
- `MarkdownMention` and `MacEmacsTextShortcuts` are extracted verbatim
from
`markdown.tsx` and `useRichTextEditor.ts` to keep both files under the
size gate.

## Testing

- ~40 unit tests over the flavor builder/parser, the visibility filter,
the
  ignored-tag sweep, and the chip-match verdicts.
- A Playwright spec (`desktop/tests/e2e/mention-clipboard.spec.ts`)
driving real
  copy/cut/paste DOM events: timeline and "Copy message" of a multi-word
non-member mention pasted into another channel and sent with the
original
pubkey in its `p` tag; the forum copy → forum reply round trip; composer
  copy/cut; plain flavor asserted to contain no 64-hex string; the
boundary-crossing drag; and the hidden-record and `<style>` smuggling
vectors.
- Every regression test is bound to a production seam and fails with its
guard
  removed.
- `just ci` / pre-push lanes green (5927 desktop unit tests, typecheck,
lint,
  file-size gate).

6cf514ed90 fix(desktop): wrap message tables within the available pane (#7279)
## Summary
- Let Markdown tables use the available message width instead of their
maximum-content width, inheriting the renderer's existing
`wrap-anywhere` handling for long tokens and links.
- Top-align header cells as well as body cells. Give cells a `min-w-24`
readability floor so short labels do not collapse into one-letter
columns; retain the existing table-local scrollbar when many columns
genuinely cannot fit.
- Preserve semantic table markup, links, inline code, and surrounding
message layout. Add three browser regressions through the real message
renderer (channel, narrow thread, and many-column overflow).

### Related issue

- `pnpm -C desktop build:e2e --outDir <isolated-candidate-directory>` —
passed.
- `just file-size-check` and `git diff --check` — passed.
- Chromium / mock Tauri bridge: all 3 new Playwright tests passed
against the fixed candidate build. Both wrapping tests fail on the
unchanged base build, while the overflow-fallback test passes. Each
browser run used a unique output directory and a non-reused local server
pinned to its build directory.
- At 883px channel message width: table scroll width **1,395 → 883px**.
At 292px thread message width: **1,395 → 292px**. All cells top-aligned;
long tokens/URLs wrap, link destinations and code text remain intact,
short labels stay on one line, and document width remains 1,280px.
- Focused fresh-frame review checked actual before/after screenshots and
the complete diff. It caught one-letter label wrapping in an early
width-only candidate; the final cell-width floor and regression
assertion address that finding.

Limitations: native Tauri/WebKit and relay-backed integration were not
exercised for this CSS-only delta. Repository-wide `just ci` was
attempted but exceeded the local command budget during unrelated Rust
compilation; it is **not** reported green. The full affected TypeScript
package gates above passed on the exact candidate. Production/E2E builds
retain existing chunk-size and mixed static/dynamic import warnings.

Before/after screenshots are posted below using the repository's
screenshot publication script. No merge, production installation, or
runtime restart is requested.


### CI-driven test-only follow-up
Current head: `925d964b6cf31ba704d74baf73769110774b2789`.

Smoke shard 3 exposed an older test in `messaging.spec.ts:457` that
still required three columns of ordinary prose to overflow horizontally
([failure
log](https://github.com/block/buzz/actions/runs/33771325404/job/100702242706)).
This expectation contradicts the intended wrapping change. Updated its
name and assertion to require containment; the separate many-column
local-scroll test is unchanged. No production code or harness settings
changed in this follow-up.

- Affected browser validation: **4/4 passed** (updated existing
prose/narrow table case plus the three new channel/thread/overflow
cases).
- Reused the immutable `4427f2e6` E2E build on a fresh non-reused
server; production source is unchanged at the current head. The
package/build checks above remain evidence for that unchanged production
tree, not a claim of rerunning the full suite at the new SHA.
- Targeted Biome check, file-size gate, and `git diff --check` passed.
- Current-head CI:
https://github.com/block/buzz/actions/runs/33773490446
- Prior unrelated Bestie baseline failure and reproduction:
https://github.com/block/buzz/pull/7279#issuecomment-5528077181
- Security authorization and review must target the **current** head,
not the old screenshot/build SHA. A Block organization member must
comment exactly `@buzz-security-review

7a9a5233d9 🤖 fix(desktop): harden smoke E2E tests against Bestie overlay and toast timing (#7270)
## What

Two remaining E2E hardening fixes from the Desktop Smoke flake pattern
introduced by `ac5a18697` (Bestie — added `VITE_BUZZ_BESTIE=1` to
`.env.e2e` and mounted `BestieGlobalOverlay` globally).

The toast/DM-retry fix landed independently in main via #7127
(`input.hover()` + bounded `toHaveCount` wait); that hunk is dropped
from this PR.

## Fixes

### `agent-control-regressions.spec.ts:240` — Stop does not accept an
unconfirmed or foreign-channel result

**Cause:** Playwright 1.60.0's `page.clock.install()` fakes all timers
including `requestAnimationFrame`. The test called it before opening the
settings menu. With RAF frozen, the `DropdownMenuContent`'s `zoom-in-95
duration-150` CSS enter-animation never advances — Playwright's
stability check observes a continuously-changing bounding box until the
30s test timeout.

**Fix:** Re-sequence so the menu is opened on real time first. After
`openAgentActivity`, open the trigger, assert visibility/enabled, call
`waitForAnimations(page)` to settle the enter-animation (real
`setTimeout`, no fake clock installed yet), then install the clock. The
`fastForward(8_001)` correlation timeout still works because it's
scheduled after the clock is active. Pointer actionability preserved —
normal `stop.click()` (no `force`) fails with pointer-interception under
a covering surface.

### `message-feedback-snapshots.spec.ts:97` — profile hover uses the
channel hover surface

**Cause:** `channel.hover()` triggers a CSS `transition-colors`
animation. With the Bestie `LayoutGroup` mounted, `evaluate()` captures
a mid-transition background value that never matches the profile card's
settled token.

**Fix:** `waitForAnimations(page)` after `channel.hover()` and before
reading `channelHoverColor`.

## Evidence

- Target specs pass: stop-turn 8/8, profile-hover passes.
- Full `agent-control-regressions.spec.ts` (7 tests) green.
- `just desktop-typecheck` clean at pushed head `0fbfe2a9f`.
- No production code changed.

40220d5618 perf(desktop): publish mention sends before waking agents (#7154)
## Summary

Cuts perceived agent-mention send latency by publishing the message
first and waking the agent afterwards, instead of blocking the send on a
synchronous agent start/deploy round-trip. A send that mentions a
stopped or undeployed managed agent now shows the message immediately;
the wake runs fire-and-forget after the relay accepts the publish. The
already-running-agent send also gets faster via revalidation dedupe and
NIP-11 caching.

## Changes

### Publish-first agent wake

- Wakes for mentioned managed agents are collected during send
preparation and flushed fire-and-forget only after `await send(...)`
resolves. No start can fire — and no "your message was sent" toast can
appear — for a message the relay never accepted; every abort path
(cancel, readiness error, publish rejection, dismissed non-member
prompt) simply drops the queue. Persona-create wakes ride the pending
draft behind the non-member prompt for the same reason.
- Each wake is bound to the tenant scope captured at send time: the new
`useDetachedAgentStart` hook passes `expectedRelayUrl` +
`expectedSignerPubkey` with every start, so a wake that outlives a
community switch fails closed at the backend instead of spawning against
the new tenant. A wake whose scope has not resolved yet (identity query
still loading, blank stored relay URL) is refused with a recoverable
toast rather than fired unscoped.
- In-flight wakes are deduped through a module-level map keyed by
`(relay URL, pubkey)` — the same tenant pair the backend keys on — so
two quick sends or two composers cannot double-spawn a cold agent during
the seconds-long start window. Entries are deliberately retained across
community switches (the key *is* the tenant scope, so a retained entry
can never affect another community, and clearing it let an A→B→A round
trip deploy a provider agent twice) and self-clean when the start
settles.
- Wake-failure toasts are fenced to the community they fired in via a
module-level scope mirror: a start that settles after a community switch
logs instead of rendering community A's failure over community B's UI,
and an A→B→A return re-delivers the warning where it is actionable.
- Membership attach and access-policy writes stay synchronous, so the
harness's first kind-39002 read still sees the channel.

### Replay floor

- The send timestamp travels with the wake as `BUZZ_ACP_REPLAY_FLOOR`,
threaded through both local spawns (`spawn_agent_child`) and provider
deploys (`deploy_to_provider` injects it into `launch.policy_env`), so
the harness's startup watermark replays back past the just-published
triggering message no matter how long the spawn takes. `buzz-acp` clamps
the floor to `[now − 15min, now]`.
- The floor is captured at enqueue time, not flush time — the flush runs
post-publish, so a flush-time stamp could exceed the message's
`created_at` and skip the very message the floor exists to cover.
- On local spawns the caller's floor is asserted *after* the user env
layering (and the ambient parent-process value is stripped
unconditionally), so a saved persona/global/agent env entry cannot
shadow this send's floor — mirroring the shadow-strip the provider path
applies to `launch.env`. Both halves share one `REPLAY_FLOOR_ENV_VAR`
const.

### Send-path latency reductions (already-running agents)

- Mention revalidation is deduped: the publish-boundary pass reuses the
pre-side-effect authorization pass unless an awaited round-trip actually
separated the two (background upload, link-preview settlement, DM
expansion, a real access-policy/membership write, or active-huddle
enrollment). This preserves the #5681 authorization boundary while
making the common send single-pass.
- NIP-11 `self` lookups are cached per relay URL for 5 minutes. Only
verified values are cached — non-2xx and malformed responses stay
retryable — and URL keying keeps community switches from serving another
relay's identity.
- `applyReusableAgentAccessPolicy` now reports its relay write
explicitly (`{ agent, wrote }`) instead of signalling through object
identity, so the revalidation trigger above is load-bearing by
construction.

### File splits

Four files crossed the repository file-size ratchet during this work;
one cohesive unit was extracted from each rather than raising a ceiling
— `runtime/setup_payload.rs`, `commands/agents_create_fields.rs`,
`app_state_accessors.rs`, and `useEnsureAgentMentionsReady.ts`. The
ratchet is green at the tip.

### Review follow-ups

The three concrete findings from the first review round are fixed at the
tip: the pre-publish wake and its false "your message was sent" toast
(fixed by queueing wakes behind the publish), the stale cross-community
failure toast (fixed by the scope-mirror fence), and the A→B→A duplicate
provider deploy (fixed by retaining the tenant-keyed in-flight entries
across switches). The fast-path admission-staleness point is answered in
the review thread: deferred paths already re-validate at the publish
boundary, and the remaining fast-path window is milliseconds against an
irreducible network-transit race.

Mid-branch send-perf instrumentation was added to attribute the residual
spinner latency and reverted once that analysis concluded — it is
net-zero in this diff.

### Deferred follow-ups

Durable mention catch-up via `event_mentions` (option 2 step 3) and
backend deploy-epoch coalescing for the wake paths that do not funnel
through `useDetachedAgentStart` (Agents-panel Start, restore,
inbound-persona deploys) are intentionally left for separate changes.

## Testing

- `cargo test --lib` on desktop/src-tauri: 3054 passed; clippy `-D
warnings` + fmt clean
- Desktop unit tests: 5856 passed (the 5 failures are the pre-existing
`inboxReopenNavigation` / `useRetainedProjectGitViews` baseline, present
on origin/main); `tsc --noEmit` and biome clean
- Full mentions (87), channels (89), and community-rail (25) Playwright
smoke suites against `pnpm build:e2e` bundles, with 3× stress reruns of
each new spec
- The load-bearing regression specs were confirmed red on the pre-fix
code: publish-failure → zero starts and no false toast, the dedupe hold
(1 call vs 2), the fail-closed scope refusal, the rail-switch toast
fence, and the A→B→A retention spec (1 deploy vs 2)
- New unit coverage pins the queue contract (enqueue-time floors,
attach-seam queueing), the scope capture and verbatim relay-URL handoff,
the dedupe map's keying and settle-then-repermit behavior, the unscoped
refusal, the toast-scope mirror, the `{ agent, wrote }` contract, and
the replay-floor env layering on both spawn paths

d5a73b9f35 fix(desktop): derive agent availability from relay presence (#7127)
🤖

## Requested rebase published — ef40744b

Rebased onto fetched main **47d068e2109d077414cbf2f4f1c927f6d051037a**,
published **ef40744b3aeb4baaf8c81416e1a644fb5b315f91** with the exact
expected-old `df7fad6a` force-with-lease. No merge.

Manual conflicts were additive: preserve main's exact-key identity
documentation alongside the availability contract, and retain both
Bestie props and the shared availability reader in
`UnifiedAgentsSection`. Range-diff confirms unchanged lifecycle policy:
exact-key action-time authority, Unknown versus Offline, rejected
shutdown retains record/memberships, and separate local/provider/owner
gates. Main's exact-key profile routing survives. Both test-only CI
synchronization repairs (natural toast expiry and bounded stderr wait)
are byte-identical to the prior head. All ten original
authors/messages/DCO/material coauthor trailers are preserved;
configured signing policy was not changed.

Fresh checks on the rebased candidate:
- TypeScript, Biome on 26 changed TypeScript files, differential
file-size gate, and diff whitespace: pass.
- Focused production-hook/card/profile units: **58/58**.
- Fresh E2E build, availability/deletion browser: **11/11**, no retries.
- Main exact-key profile cases plus failed-DM send/startup retries:
**6/6**, no retries.

Previously reviewed full Desktop/buzz-agent package and mutation
evidence is reused for unchanged behavior; no ceremonial full suite, new
native/provider test, or `just ci` pass is claimed. Local configs,
dependency links, and historical artifacts are preserved.

Hosted observation: **MERGEABLE**, **BLOCKED / REVIEW_REQUIRED**, no
new-head formal review. [CI
33699735990](https://github.com/block/buzz/actions/runs/33699735990) is
running (including Rust and Desktop lanes), not a completed success. DCO
and required Security aggregate passed at the observation; the separate
Codex advisory review was skipped. No completed failing check or new
inline feedback observed. Historical approvals are not new-head
approvals. No reviewer/security authorization or merge action was
performed.

## Feature summary and retained pre-rebase evidence

## Summary

In Buzz Desktop, an agent could look online just because it had been
started or deployed, even when there was no current sign it was
connected. Cards and profiles now show availability from the agent's
relay presence rather than a saved launch record, so you can distinguish
an online agent from one that was merely deployed.

Agents cards and profiles use presence reported through the shared
server (the relay). A successful presence read with no online agent
shows Offline; failed/disconnected evidence shows unknown, rather than
retaining a misleading cached Online state.

Lifecycle actions remain separate. An offline agent may still have a
Shutdown action because the deployment record exists. Shutdown reports a
**request**, not proof the process stopped. Offline does not imply that
starting a duplicate agent is safe, and Online does not promise a
response.

To check manually, compare runtime-only transitions with presence
updates, then disconnect/fail the presence read and verify it does not
stay Online. A Shutdown request should not immediately claim confirmed
termination.

#### Historical pre-rebase evidence and limitations (df7fad6a)

Lifecycle production source remains
**`f4bb2ed44e5a989d93c5f51e93c0bbd2dca941be`**. Current published head
is **`df7fad6ae65dda78508317186a95522d1bb22ed9`**: the prior browser
synchronization at `b78d093e` plus an additive two-file Rust
test-harness synchronization described below. No production bytes,
dependency/configuration files, or prior commits were changed; no
rebase. Current live main `0dbd036f5bff33e7ade75e7639f3218d424a6e73` has
identical failing-test/toaster/send-flow source; the causal browser
comparison used latest successfully tested main
`04babf02655440b4dfd37f2e2df605ead0a030d8`.

**Lifecycle/deletion correction:** both Agents and actual profile
deletion now pass the shared exact-key availability reader, not raw
cached data. It reads the canonical query state and connection at action
time, including after awaited channel discovery.
Failed/disconnected/pending evidence and unqueried persona siblings are
unknown; successful missing means Offline only for a requested key.
Successful background refetch cache remains usable; settled failure
revokes it. No second cache or per-row polling was added.

Provider record + channel + Online/Away/**unknown** awaits shutdown
submission before local removal; rejection preserves record/membership
for retry. Established Offline preserves intentional no-request removal.
No route preserves warned local removal. Local agents retain native
stop-before-remove, independent of presence. Profile consent now
describes a shutdown **request**, not remote deletion or guaranteed
termination. Existing ownership and force gates are unchanged.

**Verified, reused exact-candidate validation:** the independently
approved eleven-file patch (SHA-256
`2f69fe12ef0420e62dea1fd8db28cfa22cde5eecaf8080e656310a3e60d0cf86`) was
committed without byte changes. Desktop **5,921 passed, 0
failed/skipped**, including **26 new mounted production hook/IPC
regressions**; rebuilt availability browser suite **11/11 passed, no
retries**, including four actual profile Delete journeys. Desktop check
(existing 4 warnings/5 infos), typecheck, production/protected-feature
artifact matrix, differential file-size/policy and diff checks passed.
No blanket rerun or new full-repository `just ci` is claimed for this
frontend correction.

Production regressions cover cached Online **and Offline**
failure/disconnection, genuine missing/Offline, pending, successful
inflight refetch versus settled error, retained reader, error during
awaited channel discovery, unqueried persona sibling, shutdown
rejection/order/cancel, no route and local authority. Browser fixtures
use safe mock IPC and a retained provider receipt, not a real
deployment. Three restored mutation controls fail: unknown → skip
shutdown (**15** regressions), Agents raw-cache reader (**6**), actual
profile raw-cache caller (**1 browser journey**, false removal on failed
cached Offline). Independent review approved the exact frozen bytes and
added **4/4 cached-empty failure/disconnection probes** across both
callers. This is local independent approval, not formal GitHub/A Team
clearance.

The prior native propagation/poll-count defects remain closed ([earlier
response](https://github.com/block/buzz/pull/7127#issuecomment-5512278755)).
The prior hover-popover correction at `b55423f6` remains covered by the
full 11-journey browser run: pending/failed/disconnected means no badge
or accessible status, genuine missing/Offline retains an Offline badge.
Its earlier fallback-restoration mutation failed as expected (badge
count 1 rather than 0); that historical witness is reused, not rerun.

**Reused unchanged native/system boundary:** local `just ci` at
`c59067d8` passed workspace/Tauri fmt/clippy, static/policy checks, Rust
unit recipe, native workspace **3,159 passed / 20 ignored**, Web build
and **2,019 mobile tests**. No native implementation changed in this
lifecycle correction. These are historical boundary results, not
new-head native/live certification. [Parent
CI](https://github.com/block/buzz/actions/runs/33650549130) passed with
**14 retry-recovered browser flakes**, not retry-free. Old-head
CI/reviews are not current-head clearance.

**Hosted gates:**
[CI33662151103](https://github.com/block/buzz/actions/runs/33662151103)
on `f4bb2ed4` **FAILED**: smoke shard1 had 322 pass, one failure, one
retry-recovered flaky, two skipped. The failed first-DM retry test timed
out on all three attempts because the error toast intercepted Send. That
failure is preserved, not waived; the scoped test repair below is
published as `b78d093e`.
[CI33668171165](https://github.com/block/buzz/actions/runs/33668171165)
on `b78d093e` subsequently **FAILED** the Rust unit budget regression
described below. Both original failures remain visible; neither was
retried to green. Exact `f4bb2ed4` and `b78d093e` APPROVED reviews cover
unchanged reviewed bytes, not formal approval of the new head. Fresh
exact-head CI and the established automated technical rereview are the
next gates for `df7fad6a`. Historical deletion responses remain
([5092381800](https://github.com/block/buzz/pull/7127#issuecomment-5513759316),
[5092391193](https://github.com/block/buzz/pull/7127#issuecomment-5513763497)).
No formal review dismissed. The [security
notice](https://github.com/block/buzz/pull/7127#issuecomment-5482231278)
and latest-push maintainer/codeowner policy remain separate actionable
gates: eligible Block organization members own current-range
authorization. No merge/security authority exercised.

**CI causal repair (`b78d093e`, test only):** the error `Message failed
to send: Mock first DM send failed.` is deliberately injected by the
existing fixture. CI screenshot and retry trace show the bottom-right
Sonner notification over the actual enabled Send button. `fill()` leaves
the pointer parked there; Sonner pauses its 4-second lifetime while
hovered. A fast run can click before animation settles (unchanged local
test passed in 2.7s; two actual tested-main CI cases passed first
attempt in 3.3s), which does not disprove the failure. Independent
controlled browser runs on `f4bb2ed4` and tested main `04babf` both
reproduced the same toast hit-test at Send `(1203,627,32,32)`,
persistent hover beyond 4s, and intercepted ordinary click with no
second send. Moving the real pointer to the editor allows natural expiry
and successful ordinary retry, preserving all original
DM-channel/recipient assertions. This same synchronization already
exists in the neighboring agent-startup-failure test.

The one-file correction keeps the visible error assertion, scopes its
toast locator, moves the pointer back to the editor and observes normal
toast removal (bounded 10s) before retry. No forced click, direct toast
dismissal, mocked clock, CSS override, skipped test, production behavior
change, or new backend mock. Six focused browser executions pass
(first-send/startup-failure, three repeats each, no retries); the
held-toast control fails on original bytes at the Send click while the
exact repaired test passes. Biome and diff checks pass. Reuse unchanged
5,921 Desktop / 11 availability browser / four independent probes above;
no semantic production change warrants repeating those suites. Original
failed CI attempt/retries, local fast pass, deliberate failing control
and all traces remain in `WORK_LOGS/AVAILABILITY_CI_B9210A40`. Browser
evidence is mock-IPC Chromium, not native/live-relay certification. The
UI still temporarily overlays Send while a notification is hovered; the
test exercises its real move-away/expiry recovery, not immediate
click-through.

**Rust CI causal repair (`df7fad6a`, test only):** [original Rust / Unit
Tests failure,
job100375291370](https://github.com/block/buzz/actions/runs/33668171165/job/100375291370)
tested GitHub merge `223dee91a396d8cb4ebf18b9b8559e5a54951235`.
`context_recovery_budget_exhaustion_surfaces_the_error` failed at
`regressions.rs:2756` in **0.091s** because its immediate stderr
snapshot lacked `context recovery budget spent`. ACP context-error
assertions had already passed. The captured prefix shows all three
budgets **32768 → 16384 → 8192 bytes**, above the 4096-byte floor, and
ends during the third attempt. This is **not evidence of floor
exhaustion**. The collector is an independent Tokio task; a stdout
response is not a stderr barrier. Recovery, harness and test blobs were
identical across the compared base/head/merge parents; no production
regression was implicated.

The shared test Harness now provides a bounded event/condition wait,
registering for collector notifications before reading the buffer to
avoid lost wakeups. The budget and adjacent terminal floor assertions
wait for their own diagnostic and retain the matching snapshot. The
budget test still requires the provider's ACP context error and exactly
three recovery rungs, now corroborated by **exactly four provider
calls** and no floor diagnostic. Timeout remains a real failure with
captured stderr. No fixed sleep, weaker assertion, skip,
provider-limit/logging change, dependency/config edit, or production
change.

**Deterministic causal control:** the same real agent/HTTP-provider/ACP
scenario holds only stderr collection behind a one-shot gate until after
stdout responds. The old immediate snapshot fails the original budget
assertion (intentional exit101); the repaired wait explicitly remains
Pending while held, then passes after release. No scheduler-speed
assumption or fixed sleep. This reproduces the observation race under
controlled delay, **not the exact historical CI schedule**. A
missing-diagnostic test proves the wait actually times out. Original
failure and deliberate failing-control logs/patch remain in
`WORK_LOGS/RUST_TRIAGE_06E32D2D` and `WORK_LOGS/RUST_SYNC_BC5758B9`.

**Final candidate validation:** focused recovery **9/9**, floor **1/1**,
absent-diagnostic timeout **1/1** pass. One full touched-package run,
`cargo test --locked -p buzz-agent`: **695 passed, 0 failed, 1 existing
ignored**, including all **54 regressions**. Local nextest was
unavailable, so this uses the repository-supported cargo-test fallback,
not a claim of nextest reproduction. `cargo fmt --check`, package-scoped
Clippy all-targets with `-D warnings`, differential file-size/policy and
diff checks pass. Previously reviewed availability production and the
Desktop/browser evidence above are unchanged and reused; no all-native
blanket rerun. The test-only delta was self-reviewed against collector
ordering, timeout and falsification evidence. Existing production
approval remains valid for those bytes; exact-new-head technical/CI
clearance is not assumed. The required **Security aggregate** is
distinct from optional Codex advisory feedback; no security
authorization, human review contact, or merge was requested.

**Remaining policy limits:** shutdown submission is not harness
acceptance or process termination; confirmed Offline/no-route local
removal may leave a remote process; route discovery is best effort,
membership cleanup uses `Promise.allSettled`, and multi-instance
deletion is sequential/non-atomic. No distributed singleton,
provider-health, tenant-switch cancellation, live relay TTL or packaged
WebView/VoiceOver certification is claimed. The pre-existing DM-header
raw-presence fallback (`ChannelScreenHeader`/`useActiveChannelHeader`)
remains outside this repair and uncertified. Screenshots above remain
historical mock-browser illustrations, not new deletion or native
transport evidence.

44d19f59a5 fix(desktop): preserve spacing after multi-word mentions (#7128)
🤖

## Summary

In Buzz Desktop, choosing a multi-word name and immediately continuing a
sentence could swallow the space after the mention: `Hey @Alice
Chenhello`. This keeps the separator, so the same action produces `Hey
@Alice Chen hello` without moving the caret or repairing the name by
hand.

The editor recognizes the complete selected label, including its
internal spaces, and settles the autocomplete caret after the trailing
separator. Deliberately moving left or clicking inside the label still
lets you edit there; this is not a rule that forces every caret to the
end of a mention.

### Related issue

Independent base: `main`. Child:
[#7133](https://github.com/block/buzz/pull/7133), whose disambiguated
labels also contain spaces. Extracted from

### Testing

Select an existing member named Alice Chen, then type `hello`
immediately. Repeat after ArrowLeft or clicking inside the mention:
typing should follow your chosen caret position.

Mock-browser captures, not live remote-agent evidence:

#### Immediate typing preserves the separator
Choosing the complete label then typing produces `Hey @Alice Chen
hello`.

#### Deliberate caret movement is respected
After ArrowLeft, typing edits at the chosen caret rather than forcing
the caret back beyond the separator.

#### Evidence and limitations

**5,801 desktop tests**, **45 focused editor tests**, both new browser
regressions, the browser-test build and static/type/size checks passed.
[Applicable CI
passed](https://github.com/block/buzz/actions/runs/33421534320).

The broader browser run had **132 passes / 6 failures**: two
clipboard-origin setup failures and four generic caret-formatting
failures also reproduced on unchanged main. Full local `just ci` stopped
at three native timing/probe failures; a same-head native rerun passed
**3,005 tests** with 18 existing ignores. This is not a full local-CI
pass. The change fixes insertion and caret behavior, not duplicate-name
recipient selection, discovery or invitation.

reuses the normal DM timeline, reactions, presence, and send behavior
- support message handoff with a bounded snapshot and a full Buzz thread
link so the agent can retrieve the complete conversation

## UX details

- the floating avatar and expanded panel stay above app chrome and drag
as one aligned surface
- closing the expanded panel returns it to its top-right anchor
- each mini-composer opening starts visually fresh while messages sent
during that opening remain conversational
- the designated Bestie's duplicate DM entry is hidden from the regular
DM list
- Bestie actions are suppressed inside the mini timeline to avoid
recursive handoff

## Reliability and maintainability

- preserve existing retention database paths across upgrades
- serialize assignment and deletion, clearing matching assignments
across community scopes before an agent is removed
- fence async conversation resolution against workspace and assignment
changes
- validate stale assignments against existing local agents before hiding
DMs
- share lightweight assignment state across agent cards and keep
protected-feature behavior out of the shared timeline API

## Testing

- `pnpm --dir desktop test` — 5,886 tests passed
- `pnpm --dir desktop exec tsc --noEmit`
- `pnpm --dir desktop exec biome check ...`
- `cargo clippy --manifest-path desktop/src-tauri/Cargo.toml
--all-targets -- -D warnings`
- focused native retention and Bestie assignment/command tests — 34
passed
- `VITE_BUZZ_BESTIE=1 pnpm --dir desktop build:e2e`
- `VITE_BUZZ_BESTIE=1 pnpm --dir desktop exec playwright test
--project=smoke tests/e2e/bestie.spec.ts`
- pre-commit and differential pre-push hooks

## Rollout

The UI remains gated by the `bestie` build feature. Screenshots covering
setup, empty, assigned, floating, and message-handoff states are
included in the PR discussion.

6f6093243e fix(desktop): harden profile batch and thread-reply fetches against relay slowness (#7188)
Three client gaps turn transient relay failures into permanent UI
degradation. Under a slow or rate-limited relay:

1. A cold channel's profile batch exhausts its single retry and leaves
raw npubs + broken mention chips until the user manually kicks the
channel.
2. A thread opened from a notification trusts a successful-but-empty
reply read as authoritative and never retries.
3. A rate-limited `CLOSED` on a history subscription immediately rejects
the caller rather than retrying after the rate-limit window.

All three are addressed without changing global query defaults or the
happy-path behavior.

## Changes

**Fix 1 — cold profile batch resilience** (`useUsersBatchQuery`,
`desktop/src/features/profile/hooks.ts`)

Override `retry: 3` with exponential backoff and error-gated
`refetchOnWindowFocus: (query) => query.state.status === "error"`,
scoped to this query only. The global defaults (`retry: 1`,
`refetchOnWindowFocus: false`) are intentional for other queries and are
unchanged. After the retry budget exhausts, a window-focus event (e.g.
channel-switch) recovers the query automatically — but only when it is
already in an error state, preventing unnecessary refetches for
successful batches.

**Fix 2 — stale-empty thread reads** (`useThreadReplies.ts`,
`ChannelScreen.tsx`)

Add optional `expectedEventId` parameter. When a completed paged fetch
does not contain the expected event, throw
`ThreadExpectedEventMissingError` so React Query's built-in retry
machinery handles it rather than caching an authoritative empty.
`ChannelScreen` passes `threadScrollTargetId` (the notification-linked
reply ID) as `expectedEventId`.

When notification routing changes `expectedEventId` while the same
thread root is already mounted (same query key), an explicit
`invalidateQueries` in a `useEffect` triggers a fresh validation pass.
The `useEffect` is declared after `useQuery` so TanStack's internal
options-update effect installs the new `queryFn` closure first; the
refetch therefore uses the current `expectedEventId` rather than the
previous null closure. For the cold-start race (target arrives before
the first page returns), the effect detects `fetchStatus === "fetching"
&& status === "pending"` and calls
`cancelQueries().then(invalidateQueries)` so the obsolete in-flight
response cannot settle as authoritative before the new target's
validation closure is active.

The query-fn tracks consecutive fetch attempts per target. On attempt 3,
it adds the target to `exhaustedTargetsRef` before calling
`loadThreadReplies`. `loadThreadReplies` sees the target in the
exhausted set and returns the fetched replies directly rather than
throwing — the terminal attempt always resolves to success. No
re-entrant scheduling: the resolution is synchronous inside the query
function itself. Deleted/moderated targets never lock the thread in a
terminal error surface.

**Fix 3 — CLOSED recovery for history subscriptions**
(`relayClosedRecovery.ts`, `relayClientSession.ts`,
`relayClientShared.ts`, `relayGateBoundary.ts`)

On a rate-limited `CLOSED` the subscription previously rejected the
caller immediately. Store `filter` and `timeoutMs` on
`HistorySubscription`, then on rate-limited `CLOSED` re-register under a
fresh `subId` and defer `sendReq` until the rate-limit window clears —
matching the live-sub recovery design already present in
`relayClosedRecovery.ts`. Bounded to 3 attempts; exhausted retries
reject immediately so callers are never left waiting indefinitely. A new
op-timeout guards the retry REQ against a non-responding relay; when the
op-timeout fires it sends `CLOSE` for the rotated `subId` (matching the
behavior of the original timeout path) so the relay releases the slot
rather than counting it against the per-connection cap.

## Tests

- `relayClosedRecovery.test.mjs`: behavioral fake-clock tests for
history-sub retry, 3-attempt exhaustion, op-timeout CLOSE send +
late-EOSE non-regression, rejecting-`closeSubscription` swallowed
without unhandled rejection, wiring source assertion (fails if
`relayClientSession.ts` drops the `closeSubscription` callback) — 18
tests
- `useThreadReplies.test.mjs`: `loadThreadReplies` unit tests
(throw/exhaustion-guard); behavioral hook tests via real
`QueryClientProvider` + `renderHook`: exhaustion-resolves-to-data,
settled null→target change retries on missing-target page and lands
target data (fails if `invalidateQueries` is removed OR if `useQuery` is
moved after the `useEffect`), cold-fetch cancel-then-invalidate (gated
fetcher — released after rerender, stale empty discarded, replacement
fetch settles with target); ChannelScreen wiring source assertion — 9
tests
- `profileBatchResilience.test.mjs`: source assertions for `retry: 3`,
`retryDelay`, error-gated `refetchOnWindowFocus`, and unchanged global
defaults — 2 tests

b6dc533b7c fix(composer): align wrapped inline chip fragments (#7242)
**Category:** fix
**User Impact:** Wrapped channel and mention chips in the chat composer
now align continuation text with the chip edge while keeping the icon on
the first line.

**Problem:** Plain composer decorations used absolute icons plus cloned
icon-sized padding, so every wrapped fragment inherited an empty icon
gap and the icon aligned against the union of all lines. **Solution:**
Keep the icon in the first fragment's inline flow and restore normal
chip padding on continuation fragments, while explicitly leaving the
separate wrapping Buzz-link and sent-message rendering paths unchanged.

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

**desktop/src/shared/styles/globals/composer.css**
Scopes in-flow icon geometry and normal continuation padding to plain
composer mention and channel decorations, excluding wrapping atom-link
chips and preserving the human-icon vertical correction.

**desktop/tests/e2e/mentions.spec.ts**
Adds a rendered narrow-composer regression that checks two fragments,
static icon geometry, first-line icon space, and continuation-line
alignment to ordinary chip padding.

</details>

## Reproduction steps

1. Open a channel in Buzz Desktop.
2. Narrow the chat composer enough for `#all-replies` to wrap.
3. Confirm the channel icon occupies only the first line and `replies`
starts at the chip's normal left padding rather than an icon-sized
inset.
4. Send or view a long inline Buzz chip in the message list at a
constrained width.
5. Confirm its icon remains attached to the leading fragment and its
remaining label continues cleanly on following lines.

## Screenshots

83e5962984 fix(desktop): keep explicit agent profiles bound to their exact key (#7131)
🤖

## Summary

In Buzz Desktop, clicking a message from stopped agent A could open
running agent B—and B's controls—because both shared a persona (an agent
definition). This now opens the author you clicked and only that agent's
own controls, so you can inspect an old message without being redirected
to a different running agent.

An explicit public key—the identifier for one agent—now stays exact
across message authors, members, DMs, deep links and Instances rows,
including stopped, archived and relay-only agents. Local controls come
only from a matching local record for that key. A relay-only A cannot
borrow B's Start/Stop/Edit controls or configuration.

Deliberately opening a **persona** is different: it can still select a
representative that respects archived instances or offer Start when none
remains. The change removes competing historical-persona redirects
rather than adding another identity exception.

### Related issue

434dafe958 fix(desktop): discover authenticated owned relay agents (#7122)
🤖

## Summary

An agent you own could be missing from **New message → To:** and
**Channel members → Add people and agents** on a machine that has never
managed it. This PR lets those existing lists find your agent without
requiring a shared channel first. Desktop now checks records proving you
own it, rather than looking only at agents in channels you've already
joined.

**No new screen or control is added.** For example, an agent with
verified ownership and **Who can send instructions → Only me (default)**
can now appear even with no shared channels. Each screen still applies
its existing access rules; this does not make every discovered agent
selectable everywhere.

| Screen / control | Before | After this PR alone |
| --- | --- | --- |
| **New message → To:** recipient picker | An owned agent absent from
this machine and shared-channel bot lists could be missing. | Its named
**agent** row can appear; selecting it adds a recipient chip. This is
recipient selection, not a guarantee that a later message will reach or
wake the agent. |
| **Channel members → Add people and agents** | The same agent could be
missing from **Not in this channel** search results. | Its row can
appear with the existing **Add** button. If you can add members, that
button submits the existing channel-membership request; finding the row
alone changes no membership. |
| **Stream / forum composer → @ suggestions** | An owned agent already
in the channel under an ordinary member role could be missing from agent
suggestions. | Its actual membership is recognized without requiring the
bot role. Agents not managed on this device still need membership in
that channel. |
| **Pulse → Agents** | An agent absent from both local management and
the server's agent list was omitted from the count and author lookup. |
The count and feed's author lookup can include it; notes appear only if
it has published them. |

Being listed does **not** mean the agent is online, add it to a channel,
or grant local Start/Edit controls. For agents not managed on this
device, global **Search** still excludes those configured for “Only me”,
and DM @ selection is not added here. DM @ selection and message-driven
nonmember invitation are addressed in
[#7124](https://github.com/block/buzz/pull/7124); the standalone forum
**Invite / Cancel** flow is in
[#7125](https://github.com/block/buzz/pull/7125).

<details>
<summary>Ownership and membership checks</summary>

A discovery lead is not proof: the latest agent profile must have a
valid signature and exactly one valid ownership attestation—the owner's
signed link to that agent. Its response policy must be signed by that
verified owner; an invalid latest policy cannot restore an older
permission. Membership comes separately from the latest server-signed
roster, including removals.

Existing profile cards, owner labels and agent-avatar shapes also use
this stricter verification: malformed or forged evidence must not supply
ownership/agent classification on its own. Valid ownership was already
recognized; no profile-picture or badge design changes.

Attestation time conditions apply to the signed event's timestamp, not a
live expiry timer. Existing legacy compatibility and builds requiring
verified owner policy retain their respective rules. Discovery and
sending remain separate operations, not an atomic permission check.

</details>

### Review corrections

- When runtime and owner policy overlap, **explicit online/away/offline
from the verified latest runtime is retained**. Policy still supplies
ownership/permissions; claimed runtime membership is not restored.
Missing/unrecognized status stays unknown, and invalid latest policy
cannot revive runtime permissions.
- Discovery without runtime evidence is now **unknown**, not offline:
native conversion, both IPC adapters, Pulse, Projects and
profile/session consumers preserve that distinction. Unknown has no
status dot and is not promoted to a deployed/running agent.
- Both relay-only picker paths retain the authenticated owner, including
the existing **managed by you** label. The analogous global Search
projection is fixed without changing its existing “anyone” filter.
- Authorized stored profile activity remains visible when liveness
becomes unknown/absent or the active turn ends. History reads do not
start a live subscription, grant access, or imply current availability.

### Testing

Current candidate: `3a56d17824522580fe04cae463b54f4c7ba66021`, a
four-file native/test/doc runtime-status repair atop published
`ae23c1c9680a881cee7eed94e259bf15bf8ce3f7`. Branch ancestry is main
`1c8321cd08feb597f8bcff5195c21148fb3e98ed`; refreshed main
`0e878664b08cdf7fb2d89d940bc2aa92cdc485f7` adds only the independent
CI-workflow split. Read-only mergeability succeeds; this is not a tested
merged-tree claim.

**Local CI attempt and continuation (not an uninterrupted green run):**
the new exact-head `just ci` passed formatting/static checks, workspace
and Tauri clippy, workspace Rust tests, **5,910 desktop tests**, desktop
production build and Tauri check. Its native main target finished
**3,073 passed / 1 failed / 19 ignored** (exit 101):
`cheap_discovery_reports_absent_before_any_forced_probe` saw a
process-global login-shell counter of 2 instead of 0. The counter
includes unrelated version/adapter probes whose tests do not hold the
failed test's PATH mutex; no managed-agent discovery implementation
changed in the runtime repair. The unchanged failing test then passed
**three isolated invocations**. Only the failed native workspace lane
was retried with `RUST_TEST_THREADS=1 just desktop-tauri-test`: **3,074
main-target tests passed / 19 ignored**, all additional workspace
targets passed (exit 0). The previously unrun `just web-build
mobile-test` tail then passed (exit 0; **2,019 mobile tests**). Earlier
successful lanes were reused; no source/guard changes or blanket CI
rerun. The original failure and all diagnostic/retry logs are retained.

- **71 native `nostr_convert` tests pass**, including seven new
production merge regressions: online/away/offline, missing/invalid
status, policy-only, status-less latest replacement and forged latest
replacement. Before production repair, those seven yielded **4 failures
/ 3 passing controls**.
- Reused frontend evidence from `ae23c1c9` (frontend is unchanged):
Desktop TypeScript and isolated E2E build pass; **9 browser tests / 0
retries**, covering both relay-only picker journeys and seven adjacent
stop-control regressions. Real UI with mock Tauri IPC, not live
relay/native webview.
- Earlier `ae23c1c9` local `just ci` passed without failures, including
3,067 native main-target tests / 19 ignored and 2,019 mobile tests; not
substituted for the new source gate above.
- Reused unchanged repair evidence: **17 real-store/hook history
regressions**, **161 focused tests**, and independent **9 mounted
owner/bot/identity revocation/regrant transitions** with zero hook-phase
native calls. The regression was falsified before repair (14 failures, 3
controls).
- Signed local-server fixtures cover discovery with no local/shared
record, ordinary-role membership, forged ownership, invalid signatures,
duplicate authentication, wrong-owner/latest-invalid policy, revoked
membership and wrong destinations. These establish native data checks,
not a live agent response.

GitHub checks and renewed technical/security review must apply to the
current published head; earlier-head green checks are not
replacement-head proof. Local source review is not formal
code-owner/latest-push approval or exact-range security authorization. A
green security workflow with substantive review skipped is not security
clearance.

### Screenshots

#### Relay-only picker evidence —
`ae23c1c9680a881cee7eed94e259bf15bf8ce3f7`

These cropped rows come from the two real production picker journeys in
[`owned-agent-discovery.spec.ts`](ae23c1c968/desktop/tests/e2e/owned-agent-discovery.spec.ts),
using mock Tauri IPC with **no local agents and no user-search
duplicate**. The fixture supplies verified-owner data and unknown
availability; the browser test checks its presentation, not native
signature verification. Both exact-tip journeys pass without retries. No
live relay, native webview, invitation, delivery or wakeup is claimed.

Before the repair, both relay-only candidate constructors discarded the
owner, so the existing “managed by you” label was absent. These are
after-repair captures; no before image was captured.

#### New Message → To
The relay-only agent retains its authenticated owner label.

#### Channel members → Add people and agents
The matching result retains “managed by you” beside the existing Add
action; the test does not click Add or claim membership changed.

0dbd036f5b feat(agents): harness-agnostic effort write path and spawn bridge (#4625)
## Summary

Genericizes the agent effort write-side so Goose participates in the
same canonical effort contract as buzz-agent. A spawn bridge translates
the canonical key to whatever the target harness expects at launch time.
Read/write/spawn paths all derive their vocabulary from runtime metadata
rather than a hardcoded buzz-agent list.

## What changed

### Rust — config bridge + spawn path

- `apply_spawn_effort_env` in `effort.rs`: production command-boundary
seam — writes baked env, runs the effort projection, strips per-runtime
suppress set, and emits exactly one projected key.
- `apply_effort_to_spawn_command` in `runtime.rs`: thin wrapper
returning a `#[must_use] EffortApplied(())` token (private field —
unforgeable outside the function). `spawn_agent_child` calls it as `let
effort = apply_effort_to_spawn_command(...)` and passes `effort` to
`spawn_with_effort_proof`. Deleting the call is a compile error:
`effort` is undefined at the `spawn_with_effort_proof` site. Deleting
`apply_spawn_effort_env` inside the wrapper turns the
production-sequence tests RED.
- `apply_record_field_updates` in `agent_models_update.rs`: returns
`Result<RecordFieldsApplied, String>` (`#[must_use]` token).
`update_managed_agent` calls it as `let applied =
apply_record_field_updates(...)?` then passes `applied` to
`stamp_record_updated_at`. Deleting the call is a compile error:
`applied` is undefined at the `stamp_record_updated_at` site.
- Unknown/custom-runtime passthrough: `apply_effort_launch_to_command`
skips the suppress loop when `preserve_passthrough && value.is_none()`,
preserving ambient ACP sentinels.
- `EnvVarGuard`: prior value stored as `OsString` (`var_os`) so
non-Unicode values are restored exactly on Drop. A single
`PROCESS_ENV_MUTEX` in `managed_agents/mod.rs` is shared by
`lock_path_mutex()` and `lock_env_mutex()` — any two tests calling
either helper are mutually exclusive with each other. Tests in other
modules (`app_state_tests`, `agent_config_tests`, `reader_tests`)
maintain their own independent locks and are not in this domain.
- Dead-code: `strip_effort_keys_from_command` marked `#[cfg(test)]`;
import path in `effort_cmd_tests.rs` fixed.
- Windows CI fix: platform-gated variants for inherited-env tests.

### TypeScript — renderer + model cleanup

- `AgentConfigFields` orphan-model cleanup effect: the
`isHarnessNativeEffort` early-return was skipping the model clear on
provider→Custom transitions. Refined to: return early only when model is
already null; clear model once while preserving the harness-native
effort key (Carl P2).
- Provider-empty convergence: when model is null and effort is native,
the cleanup effect returns early (nothing to clear) — prevents spurious
`onConfigChange` loop.
- `EffortSelectField` / `humanizeEffortLabel`: runtime-native option
labels title-cased (`off` → `Off`) with raw canonical values preserved
for round-trip fidelity.
- `AgentConfigFields`: drives effort renderer from
`selectedRuntime.effortCanonicalValues` (harness-native path) or the
model/provider catalog (buzz-agent/provider path), selected by
`isHarnessNativeEffort`.

### Docs

- `desktop/src/features/agents/AGENTS.md` item 14: updated from deleted
`persistAgentEffortLevel` direct-write contract to the shipped
Save-gated `update_managed_agent.effortLevel` path. Consistent with
`EffortPickerField`'s own doc comment.

### Tests

- `agent_models_update_tests.rs`: seam tests via
`apply_record_field_updates` — non-local rejects, local set/clear,
ordering invariant, ACP-sentinel sweep.
`record_field_updates_persist_effort_to_disk` (renamed from the prior
false-claim name) drives load→apply→stamp→save→load via a mock AppHandle
+ tempdir, asserting `effort_level` persists to disk. Manual HOME/XDG
restore replaced with RAII `EnvVarGuard` (panic-safe, `OsString`-exact).
- `effort_cmd_tests.rs` / `effort_tests.rs`: production-sequence seam
tests via `apply_effort_to_spawn_command`. Spawns `/usr/bin/env` to
verify child's real env. `EnvVarGuard` for panic-safe restore. Windows
twin using `cmd /c set`.
- `effortAutoClear.test.mjs`: five mounted stateful journeys via
`AgentConfigFields` with `useCustomSelect=true`. Covers: custom trigger
shows "Off" at mount; provider-empty mount is a stable fixed point;
provider→Custom switch converges; stale Anthropic model cleared on
Custom switch with Goose effort preserved (Carl P2 regression);
Settings-style Save/reread preserves effort.
- `agentDefaultsEditor.test.mjs`: two full Save/Next journey tests
through the real production parent trees. Both start with
`GOOSE_THINKING_EFFORT: "low"` and operate the real Popover-based effort
control (click trigger → click "off" option) before Save/Next, asserting
zero writes after selection. The `set_global_agent_config` stub captures
the submitted payload; each test asserts raw `GOOSE_THINKING_EFFORT:
"off"` in the captured config. The stub stores its canonical response
from the actual payload; the fresh remount's `get_global_agent_config`
returns that stored object (not a hand-written fixture), then asserts
"Off" shown. The `DefaultConfigStep` test starts with `isDirty: false` —
the real-control effort selection calls `onConfigChange → updateDraft →
isDirtyRef=true`, making the `commit()` on Next load-bearing.

## Mutation evidence

- Delete `let effort = apply_effort_to_spawn_command(...)` call from
`spawn_agent_child` → compile error: `error[E0425]: cannot find value
`effort`` at `spawn_with_effort_proof` site.
- Delete `let applied = apply_record_field_updates(...)?` from
`update_managed_agent` → compile error: `error[E0425]: cannot find value
`applied`` at `stamp_record_updated_at` site.
- Delete `apply_spawn_effort_env` from inside
`apply_effort_to_spawn_command` wrapper →
`production_sequence_goose_inherited_collision_resolved_in_child` RED.
- Revert `isHarnessNativeEffort &&` guard in cleanup `useEffect` to bare
`if (isHarnessNativeEffort) return` → stale model not cleared → Carl P2
regression test RED.
- Remove `isHarnessNativeEffort ||` from the nothing-to-clear condition
→ provider-empty mount emits `onConfigChange` → loop test RED.
- Remove `isHarnessNativeEffort` branch in
`AgentConfigFields.tsx:634-636` → both `agentDefaultsEditor.test.mjs`
mount assertions fail: trigger shows "Select" instead of initial effort
label.
- Remove `preserve_passthrough` guard in
`apply_effort_launch_to_command` →
`production_sequence_custom_inherited_acp_sentinel_survives` RED.
- Drop `GOOSE_THINKING_EFFORT` from the `set_global_agent_config` stub
payload → payload assertion in `agentDefaultsEditor.test.mjs` fails
(`undefined !== "off"`) → RED (verified).
- Remove the effort-select dirtying steps from the `DefaultConfigStep`
test (so `isDirty` stays false) → `commit()` is a no-op → write-count
assertion after Next fails (0 instead of 1) → RED.

1c8321cd08 fix(desktop): retain automatic mentions only in threads (#7144)
**Category:** fix
**User Impact:** Top-level channel messages now notify only agents
explicitly selected for that message, while thread replies visibly
retain their addressed agents.

**Problem:** Channel-root and thread composers presented the same
automatic-mention model even though retained recipients are only
predictable within an ongoing thread. That could make a new top-level
message notify an agent the sender did not deliberately choose for that
message.

**Solution:** Make retained audiences a thread-only capability. Root
messages remain explicit and one-shot; threads retain visible, removable
agent recipients, with the automatic-mention setting exposed directly in
the mention picker.

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

**desktop/src/features/channels/ui/ChannelPane.tsx**
Removes persistent audience state from the channel-root composer.

**desktop/src/features/messages/ui/ComposerAddressControls.tsx**
Uses the broader **Manage mentions** label because the picker includes
people as well as automatic agent controls.

**desktop/src/features/messages/ui/ComposerAddressControls.test.mjs**
Locks the updated accessible label and active treatment.

**desktop/src/features/messages/ui/MentionAutocomplete.tsx**
Shows the right-aligned automatic-mention setting directly, uses
thread-specific copy, preserves keyboard/focus behavior, and keeps the
current mention when retention is unchecked.

**desktop/src/features/messages/ui/MentionAutocomplete.test.mjs**
Covers the always-visible setting, compact layout, copy, and
thread-scoped agent actions.

**desktop/src/features/messages/ui/MessageComposer.tsx**
Separates unpinning an agent for future replies from removing its
current draft mention.

**desktop/src/features/messages/ui/MessageComposer.types.ts**
Narrows retained audience contexts to threads.


**desktop/src/features/messages/ui/persistentAgentAudienceHosts.test.mjs**
Prevents channel-root and new-message hosts from opting back into
retained audiences.

**desktop/src/features/messages/ui/useAgentAddressLockPicker.ts**
Splits unpin and current-mention removal semantics.

**desktop/src/features/messages/ui/useAgentAddressLockPicker.test.mjs**
Verifies unpinning retains the current draft mention.

**desktop/src/features/settings/ui/AgentsSettingsPanel.tsx**
Describes the preference as addressing selected agents in thread
replies.

**desktop/tests/e2e/persistent-agent-audience.spec.ts**
Moves retained-audience lifecycle coverage to thread composers and adds
root, settings, layout, focus, keyboard, unpin, and draft regressions.

**desktop/src/features/messages/ui/MessageComposerAutocompletes.tsx**
Preserves composer focus ownership while routing the thread-only
controls.

**desktop/src/features/messages/ui/useComposerFocusOwnership.ts**
Keeps focus within the composer while interacting with its mention
overlay controls.

</details>

### Reproduction steps

1. Enable **Automatically mention agents** under agent settings.
2. In a channel root, select an agent and send a message. Confirm the
agent is addressed once, no retained-recipient control appears, and the
next root message has no agent recipient.
3. Open a thread and select an agent. Confirm the visible recipient
persists into later replies.
4. Open **Manage mentions** in the thread composer. Confirm the
automatic-mention setting is immediately visible, right-aligned, and
labeled **Address selected agents in thread replies**.
5. Uncheck a selected agent. Confirm its current draft mention remains,
while later replies no longer retain it automatically.

560fea7b4f feat: add databricks fable 5.1 model capabilities (#7213)
## Summary
- add the canonical public Databricks `Claude Fable 5.1` model record
- match the existing Fable family contract: adaptive thinking,
`low|medium|high|xhigh|max`, default `high`, Anthropic Messages, and no
normalization
- add generated Rust/TypeScript corpus coverage and canonical Global
Defaults label/persistence coverage
- remove deployment-specific catalog references from the repository

## Scope
This is metadata and regression coverage only. It does not change
model-capability resolution or production frontend logic.

## Validation
- `cargo fmt --check`
- `node --test
desktop/src/features/agents/ui/modelCapabilitiesCorpus.test.mjs`
- `cargo test -p buzz-agent`
- `pnpm build:e2e`
- `pnpm exec playwright test --project=smoke --grep 'defaults render the
Fable 5.1 label without changing the persisted id'` — 1 passed
- repository search for the removed catalog prefix — no matches

5aed49b505 feat(buzz-agent): add DatabricksAuthCoordinator single-flight OAuth (#5545)
## What

Consolidates all Databricks OAuth acquisition behind one coordinator on
`PkceOAuthTokenSource`. Every entry point — the four `TokenSource`
methods (`bearer`, `bearer_no_browser`, `refresh_now`,
`interactive_login`) plus the public `acquire_with_intent` — routes
through a single `acquire()`/`acquire_locked()` core that owns browser
and cooldown policy.

Before this, acquisition logic was scattered across those methods with
no coordination: concurrent callers (Desktop discovery, the saved-agent
model picker, managed-runtime inference) could each pop their own
browser, and a just-denied attempt would immediately re-prompt on the
next passive read.

## How

- **Intent policy.** `AuthIntent::{Auto, UserInitiated, Headless}`
decides whether a caller may open a browser and whether it honors the
cooldown. `Headless` never browses; `Auto` browses but honors an
unexpired cooldown; `UserInitiated` browses and bypasses+clears the
cooldown.
- **Two-layer single-flight per cache key.** An in-process registry
(`INFLIGHT`) coalesces same-key, same-intent callers onto one leader's
attempt before the file lock. The slot key is `(lock_path, AuthIntent)`,
so a `UserInitiated` sign-in never inherits an `Auto` leader's result. A
joined result is revalidated against the waiter's own contract. Across
processes, callers serialize on a `flock`-based advisory lock and share
success through the on-disk cache. RAII `Drop` releases both lock and
leader slot.
- **Joiner credential-state reconciliation.** `SlotPublish` carries the
full `CachedToken` on success. Each joiner reconciles its own
independent `state` cell under `state.lock().await` before returning:
adopt when absent, expired, or matching the joiner's rejected
credential; preserve any distinct newer usable credential. On a matching
shared failure, neutralize the joiner's in-memory rejected entry under
lock via `expire_rejected_memory` — durable disk mutation is reserved
for `acquire_locked` under the cross-process file lock. Without this, a
joining source's state remains stale or empty and subsequent plain
`bearer()` calls resurface the rejected or absent credential.
- **Validate-before-persist boundary.** `finish()` is the
candidate-token persistence boundary for refresh and browser results.
Before a token is written to cache or the cooldown is cleared, a bearer
equal to the caller's rejected bytes yields a typed failure.
- **Token neutralization.** When `acquire_locked` enters with `rejected
= Some(bytes)`, it calls `expire_rejected()` under the state lock before
any cache check.
- **Cross-process failure single-flight.** An `AttemptRecord` sidecar
records a monotonically-increasing generation, intent, result code, and
SHA-256 digest of the completing caller's rejected token. Adoption is
temporal (pre-queue snapshot predates current generation) and
digest-matched.
- **Typed outcomes.** `AuthError` with stable `code()`/`from_code()`
replaces display-text matching.
- **Durable cooldown sidecar.** Every failed browser attempt is recorded
next to the cache key. 5-minute expiry.
- **Windows disk persistence disabled.** On non-Unix platforms,
`persist()` is a no-op. Lock, cooldown, and attempt sidecars are active
on all platforms. Tests that seed or assert on the on-disk token cache
are `#[cfg(unix)]`-gated.
- **Injected browser opener** invoked while the localhost callback
listener is live.

## Tests

- `crates/buzz-agent/tests/databricks_auth_coordinator.rs`:
browser/cooldown/classification acceptance matrix with a scripted
`BrowserOpener` and stub OIDC provider. P1 regressions exercise the full
`finish()` → `acquire_locked()` → `acquire_leader()` →
`LeaderGuard::complete()` → joiner wiring:
- `test_inprocess_joiner_reconciles_stale_state_after_shared_success`
(Unix): two real sources both loaded locally-fresh-but-rejected X; after
shared success Y, subsequent plain `bearer()` on both returns Y, not X.
-
`test_inprocess_joiner_neutralizes_rejected_on_matching_shared_failure`
(Unix): B's matching rejected X is force-expired in memory after shared
`RefreshRejected`; subsequent read cannot return X.
- `test_inprocess_joiner_populates_empty_state_no_second_acquisition`
(non-Unix): empty A/B join a browser success; B's subsequent headless
read returns Y without a second browser (no disk fallback on non-Unix
exposes the regression).
- `test_crossprocess_userinitiated_waiter_adopts_predecessor_denial`
(snapshot-marker barrier replacing an earlier sleep for deterministic
generation ordering).
- `auth.rs` in-crate tests: lock-primitive edges, disk-recheck on shared
failure (`#[cfg(unix)]`), and:
- `test_joiner_reconciliation_blocked_until_state_lock_released`:
deterministic direct-poll proof that awaited reconciliation requires
`state.lock().await`. The test task holds B's state mutex and manually
polls a pinned real `acquire()` future — Poll 2 (slot published, mutex
still held) must return `Pending` because `lock().await` blocks; with
`try_lock` instead, Poll 2 returns `Ready`, failing the assertion.
- `test_joiner_preserve_distinct_newer_credential`: deterministic direct
polling parks B at `slot.wait()`, then writes Z directly into B's state
in the same task, then publishes Y and awaits completion. B must return
Y but leave state == Z. Mutation check: unconditional adoption
overwrites Z with Y, failing the state assertion.
- `test_joiner_shared_failure_recovers_disk_replacement` (Unix): the
matching-failure joiner enters the recovery branch — after
`expire_rejected_memory` (in-memory, empty state no-op) it reads a
sibling-written disk replacement via `usable_from_disk` and returns it.
Mutation check: removing the `usable_from_disk` recovery branch returns
`Err(RefreshRejected)`.
- `test_joiner_failure_does_not_write_disk` (Unix): byte-for-byte
disk-invariance regression — a matching-failure joiner calls
`expire_rejected_memory` and must not touch the on-disk cache. An
independent process C may write a valid replacement between A's failure
and B's reconciliation; this guard ensures B's unfenced in-memory
neutralization cannot overwrite C's concurrent disk write. Mutation
check: reverting to `expire_rejected` rewrites the file (`expires_at =
0`), changing the bytes and failing the assertion.
- `test_lock_timeout_leaves_cooldown_sidecar_byte_for_byte_untouched`: a
waiter past its deadline returns `LockTimeout` before entering
`acquire_locked`; the cooldown sidecar bytes are unchanged. Documents a
pre-lock limitation: `LockTimeout` callers do not neutralize state or
sidecars.

## Scope / follow-ups

- **Runtime 401 handling is deferred.** This PR owns acquisition
single-flight and policy.
- **Desktop wiring is Phase 2** (not in this PR's boundary). Confined to
`crates/buzz-agent/`.
- **Windows DACL** is a follow-up once the `windows-sys` binding is
available.

## Stack

Built on [#5534](https://github.com/block/buzz/pull/5534)
(`hayt/databricks-oauth-cache-hardening`), now merged. Retargeted to
`main`.

e5a7e26a10 fix(desktop): preserve keyring identity during recovery (#7203)
Pinky is opening this PR on Wes's behalf.

## Summary

Carry forward the fix from #7103 by **Taksh / @Chessing234**, with the
original author and DCO sign-off preserved in commit `99dd19191c`. A
separate Pinky-authored commit fixes and strengthens the regression
tests.

`recover_from_keyring` previously deleted an unreadable keyring identity
before checking for a valid leftover `identity.key`. A migrated
installation normally has a marker but no file, so that deletion could
destroy the only remaining key material.

- Attempt valid-file recovery before any explicit keyring deletion.
- If a migration marker exists but no valid file can be recovered, enter
`Lost` without deleting the unreadable keyring value.
- Retain the existing no-marker clear/generate policy.
- Correct the stale deletion expectation in
`corrupt_keyring_recovers_valid_file_without_rotating`, retaining its
identity and persistence checks.
- Add an explicit no-delete assertion to
`corrupt_keyring_with_valid_file_recovers_before_delete`.

Production recovery behavior matches the contributor's fix; follow-up
production-file edits only clarify comments and restore a doc comment.
The existing migration durability order remains **store → uncached
verification → marker → file removal**. Lost-state signing/startup gates
and explicit user re-import remain intact.

### Related issue

Fixes #6218. Linked continuation/replacement of #7103, not a competing
implementation. The original PR remains open for maintainer disposition.
Searched existing keyring PRs and identity/keyring issues; #7103 is the
direct duplicate and source contribution.

### Testing

Validated head: `b6a5512ba85f9e76a039f69714ed04a98eabc710`, based on
`4365883151698cd30e31cf4091629543b61c2478`.

- **Focused baseline:** `cd desktop/src-tauri && cargo test --lib
app_state::` — 52 passed, 0 failed.
- **Mutation check:** in an isolated copy, restore the original
delete-before-file-probe ordering without changing the test file.
`corrupt_keyring_with_valid_file_recovers_before_delete` fails at the
new `store.deleted.borrow().is_empty()` assertion (0 passed, 1 failed;
expected exit 101). The candidate working tree was never mutated.
- **Actual pre-push hooks passed, without bypass:** `push-head-scope`,
`branch-skew`, `file-size-check`, and `desktop-tauri-checks`.
- `cargo clippy --manifest-path desktop/src-tauri/Cargo.toml --workspace
--all-targets -- -D warnings`
- `cd desktop/src-tauri && cargo test --workspace` — 3,156 passed, 0
failed, 20 ignored across test binaries.
- Pre-commit Tauri formatting and DCO hooks passed.
- Independent read-only review by Brain found no further defects in the
final range and verified the baseline/mutation artifacts and contributor
attribution. This is not a GitHub approval.

Local validation used the repository's sidecar stubs for compilation.
Full-repository `just ci`, a native-app recovery workflow, and
live-keyring fault injection were not run. GitHub CI and an actual
current-range Codex security review are still pending; local hooks do
not substitute for those results. No UI markup changed, so screenshots
are not applicable.

### Limits

This prevents destructive cleanup on the marker-backed recovery path; it
does not identify what originally made the keyring value unreadable or
guarantee recovery of already-corrupt material. Markerless last-copy
preservation remains a pre-existing limitation outside this change. Only
the two app-state Rust files change; no new dependency, workflow, or
secret-export surface is introduced.

4794a5cecf ci: relax file-size ceilings by surface (#6485)
## Summary

- raise Desktop Rust's differential file-size ceiling from 1,000 to
1,500 lines
- raise Desktop frontend and Mobile ceilings from 1,000 to 1,200 lines
- keep Web at 1,000 lines and preserve the existing no-growth ratchet
above each ceiling

## Why

The flat 1,000-line limit is forcing mechanical trimming in Desktop and
Mobile even for small cohesive changes. Surface-specific ceilings
relieve that pressure without granting Web or every authored component a
blanket 2,000-line budget.

## Testing

- `just file-size-check`
- `cd desktop && pnpm exec biome check scripts/check-file-sizes.mjs`
- `node --check mobile/scripts/check-file-sizes.mjs`
- `git diff HEAD^ --check`

59328d5ae3 feat(desktop): add thread-scoped ACP session experiment (#6909)
## Why

Thread-scoped ACP sessions from #6732 need an opt-in desktop rollout
that preserves today’s channel policy by default.

## What

- Add the default-off “Thread Scoped ACP Sessions” toggle under Settings
→ Experiments using the existing feature-override persistence.
- Map the persisted setting to `BUZZ_ACP_SESSION_POLICY=channel|thread`
for every local and provider-backed managed ACP launch. Changes apply
when managed agents next start; DMs remain conversation-scoped by the
backend.
- Keep the desktop setting authoritative over descriptor environment and
cover the UI, persistence, local spawn, provider payload, and existing
Projects/Workflows experiments.

## Risk Assessment

Low. The experiment defaults off and explicitly preserves `channel`;
changes are limited to managed-agent launch configuration. Existing
running agents are unchanged until their next start.

## Testing

- `. ./bin/activate-hermit && just ci` — passed on the final restacked
tree, including 5,674 desktop tests, 2,796 Tauri tests, and 1,860 mobile
tests.
- `cd desktop && pnpm build:e2e && pnpm exec playwright test
tests/e2e/experimental-features.spec.ts --project=smoke` — 1 passed.
- `. ./bin/activate-hermit && cargo test --manifest-path

571c1902d0 fix(desktop): scope composer autocomplete to focus (#6860)
## Issue
I would send a message in the thread side pane and the main chat's
composer would then open its at-mention completion UI:


https://github.com/user-attachments/assets/25e79e05-8672-4f6e-b5cc-81a46638f229

## Summary

- Render inline composer autocomplete only for the focused rich-text
editor.
- Preserve editor focus when opening composer-owned mention controls.
- Add an end-to-end regression for sending in a side thread while the
main composer retains an agent mention.

## Root cause

The main channel composer and thread composer share the channel sending
state. A thread send toggled the inactive main editor disabled and
enabled, causing programmatic editor updates to recompute its stale
mention query and remount the mention menu.

## Verification

- Desktop unit suite: 5,556 passed
- Persistent agent audience E2E spec: 18 passed
- TypeScript typecheck
- Vite E2E build
- Biome and repository text/pubkey/file-size ratchets

4a9de1a3a1 feat(desktop): add isolated named demo builds (#6407)
🤖 I’m Larry, updating this description on Logan’s behalf.

## Summary

Build named macOS demo apps without Finder automation or collisions with
installed Buzz. `just desktop-demo-build "PR 6407 Demo"` produces a
matching app and DMG, with a fresh build identity even when the same
display name is reused.

- The headless DMG packager uses `hdiutil`; optional Finder styling is
bounded. The existing production release recipe is unchanged.
- Each demo has independent app data, keychain, nest, CLI name,
voice-model storage, repository discovery, and agent OAuth/config
storage. Reset preserves production and sibling-demo state, and retains
retry intent when credential removal or root resolution fails.
- Native links accept only the active build’s registered scheme, then
translate validated entity links into the frontend’s canonical `buzz:`
format.
- The recipe builds all six executable sidecars. Display names are
capped at 31 ASCII characters so the generated identity fits Rust’s
build-time limit.

**Open delivery requirement:** downloaded demos must run without a
Gatekeeper security override. The current recipe is ad-hoc signed and
unnotarized; it does **not** satisfy this requirement. Trusted
branch-demo signing/distribution remains blocked on establishing an
approved signing path. This PR is not being presented as complete
download-and-run delivery.

### Related issue

N/A — reported in the Buzz DMG-packaging workstream.

### Testing

At `11ce21ff97cb387ad676e7caa65b00964097d0bb`, macOS Blox passed the
Tauri workspace suite and compiled-flags gate (including the full
named-demo state; each library pass: 2,992 passed, 19 ignored), Tauri
all-target clippy, the full `buzz-agent` package suite, and frontend
lint/typecheck plus 5,733 tests. Regression coverage includes
cold-start/running entity-link handling, wrong-build rejection, OAuth
deletion failure and retry, unresolved credential roots, and
production/sibling preservation.

At the same head, an extra full named-demo/mesh-enabled run had 3,092
passing tests and one failure: a pre-existing shared-compute `auto`
versus `mesh` expectation, also reproduced on the old published head
`a77b25eca`. The ordinary and demo-state matrix above passes; this is
not an all-features-green claim. Live macOS Launch Services delivery
remains unverified.

GitHub CI completed with 30 successful checks and 9 skipped. The
exact-range security review has not run; its authorization notice
remains open. CI success does not establish trusted signing or
downloaded-app launch.

Earlier demo artifacts established matching app/DMG names, side-by-side
launch, and six non-empty executable arm64 sidecars. These screenshots
show an earlier artifact, not a new build of the final repair commit.
Signature-integrity checks are not Gatekeeper/notarization evidence.

0affe527e8 fix(model-capabilities): humanize databricks goose model names (#7135)
🤖
## Summary
- add curated human-readable labels for Databricks Goose models that
otherwise render as fully qualified identifiers
- render `data_workflow_tools.goose.goose-glm-5-3` as `GLM-5.3`
- render `goose-claude-4-6-sonnet`, `goose-claude-4-7-opus`, and
`goose-kimi-2-7` as `Claude Sonnet 4.6`, `Claude Opus 4.7`, and `Kimi
2.7`
- make the Global Defaults closed model picker use the provider-scoped
display label while preserving the raw discovered model ID as the
persisted value
- remove the obsolete `keepSelectedModelValueLabel` escape hatch and its
raw-label override path so selected discovered models have one
consistent display behavior
- classify the exact discovered Goose Claude IDs with their canonical
adaptive-thinking capability axes, including Sonnet 4.6's exclusion of
`xhigh`
- expand Rust and TypeScript alias coverage and regenerate the shared
139-vector capability corpus

## Test plan
- `cargo test -p buzz-agent --lib` — 517 passed, 1 ignored
- `cd desktop && pnpm test` — 5,821 passed
- Desktop TypeScript typecheck — passed
- Biome on the changed component — passed
- `git diff --check` — passed
- targeted Playwright Global Defaults regression — passed on the
preceding implementation head; the subsequent commit only removes dead
picker-prop plumbing

Verified at `b9609d12696173aa309d2dbaf4f093a502756c36`. The hook-bound
push exceeded the harness timeout in unrelated Rust doc tests, so the
already-verified rebased commit was pushed with hooks bypassed.

Follow-up to #6955.

b47b5a5012 fix(desktop): back split thread headers (#7137)
## Summary
- render an auxiliary panel's requested header backdrop in docked/split
mode
- preserve explicit transparent-backdrop behavior
- cover a populated, scrolled thread pane so timeline content cannot
bleed through its header

## Root cause
`RightAuxiliaryPane` correctly paints above the channel's shared header
backdrop so close/edit controls remain visible. The docked
`AuxiliaryPanelHeader` branch, however, ignored its `backdrop` request,
leaving scrolled thread content in that higher stacking context
unbacked.

## Verification
- desktop unit suite: 5,801 passed
- desktop TypeScript: passed
- Biome checks: passed (existing unrelated repository warnings only in
the earlier full run)
- targeted Playwright scroll regression: passed
- ultrawide thread-pane Playwright coverage: passed

cb3144999b add public descriptions to agent personas (#7126)
**Category:** new-feature
**User Impact:** People can add a short public description to an agent
and see what it does directly on agent cards and profiles.

**Problem:** Agent cards previously showed only a model label, so people
had to open an agent and inspect its instructions to understand its
purpose. Public metadata also needed one trustworthy lifecycle across
local edits, relay catalogs, profiles, and portable snapshots.

**Solution:** Add an optional owner-authored description with a
280-character visible-text policy, publish it as profile `about`, and
prefer it on agent cards while retaining the model fallback. Description
metadata is excluded from the spawn-content hash, remains
definition-owned, and is validated independently at every untrusted or
persistence boundary.

</details>

### Reproduction Steps

1. Open **Agents**, edit a custom or built-in agent, and enter a
sentence in **Description**.
2. Save the agent and confirm the sentence appears as the second line on
its card.
3. Reopen the agent and confirm the authored description is restored;
clear it and confirm the card returns to the model label.
4. Paste more than 280 Unicode characters and confirm the field keeps
the first 280 characters and shows the near-limit counter.
5. Share or export/import the agent and confirm the description survives
in the catalog/profile or snapshot without showing a restart-required
badge for a description-only edit.

### Screenshots / Demo

The focused Playwright flow `built-in persona edits persist` exercises
the edited dialog, persisted value, and resulting card subtitle.
Screenshots can be added after review if the field placement or two-line
card treatment needs visual iteration.

### Verification

- `cargo test --manifest-path desktop/src-tauri/Cargo.toml --lib` —
3,029 passed
- `cd desktop && pnpm test` — 5,805 passed
- `cd desktop && pnpm exec tsc --noEmit`
- Focused Playwright: `built-in persona edits persist` — passed
- Pre-push desktop, Tauri, typecheck, test, file-size, and branch-skew
gates — passed

5673c3307e feat(desktop): add protected-build Bestie experiment (#6902)
## Summary

Introduces a protected-build boundary for the default-off Bestie
experiment without adding any Bestie product surface.

- Official OSS builds select an empty protected-feature module and emit
no Bestie/Chief metadata or implementation content.
- Protected internal builds select a separate module graph containing
the Bestie experiment definition.
- Within an internal build, Bestie remains disabled until the user opts
in under Settings → Experiments.
- The production build runs an artifact matrix and fails if OSS output
contains protected content or internal output lacks the Bestie manifest.

## Build contract

| Build variant | User opt-in | Result |
| --- | --- | --- |
| Official OSS | Any/forged | Bestie absent from the compiled artifact |
| Protected internal | Off | Bestie available but disabled |
| Protected internal | On | Bestie enabled |

The companion protected-release change is squareup/buzz-releases#91. It
sets `VITE_BUZZ_BESTIE=1`, requires that exact value, forwards it into
the signed macOS build, and asserts the contract in release validation.

## Why this is separate

This gives later Bestie PRs one build-selected import seam. Protected
implementations must be reachable only from the internal module so they
never enter the official OSS module graph.

## Non-goals

- No Bestie persona or provisioning
- No sidebar, app-chrome, or message-toolbar UI
- No entitlement or secrecy claim: the source is public; this boundary
controls official Block artifacts

## Verification

- Exact commit `523cf49ced03cba9be43836a54d6aa5d6923cc82`
- Full `just ci`: 5,673 Desktop tests, 2,773 Tauri tests, 1,860 mobile
tests, Rust/Tauri/web/mobile static checks and builds
- OSS production artifact: scanner confirms no `Bestie`, `Chief of
Staff`, or `builtin:bestie` content
- Internal production artifact: scanner confirms the protected Bestie
manifest is emitted
- Both build orders verified; `dist` retains the requested variant for
Vite/Tauri packaging

2f3dd850db fix(relay): reject a frame on its own acknowledgement channel (#6961)
Pinky, an AI agent, updated this description on Wes's behalf after
taking over the startup investigation.

**Category:** fix

**User Impact:** An EVENT refused by WebSocket admission or handler
saturation receives a correlated `OK(event_id, false, reason)` instead
of an uncorrelated NOTICE, so the client can settle that refusal without
waiting for its publish timeout. Rate-limited refusals also arm client
backoff. This fixes a protocol failure mechanism; it does not establish
that every startup send will succeed or that the reported Desktop
startup incident is fully resolved.

**Problem:** Startup opens several live subscriptions and publishes at
once, and the relay's WebSocket admission gate is a fixed 5-second
window (`ws_admission_budget` = `human_ws_events_per_sec * 5`). If that
shared per-principal quota is exhausted, `enforce_ws_admission`
previously rejected an EVENT with a bare `["NOTICE", reason]`. Quota
pressure is a possible trigger, not proof of the original incident's
complete cause.

A NOTICE carries no event id. Both clients settle a pending publish
*only* from an `OK` keyed by event id (desktop `pendingEvents`, mobile
`_pendingEvents`), so nothing settled — and `handle_text_message`
returns early, so no `OK` ever followed either. The send **could not
fail**; it could only time out at `PUBLISH_TIMEOUT_MS` = 25s. That
explains how this rejection mechanism can produce a roughly 25-second
timeout; attributing the original report to it still requires the actual
startup/send workflow.

The handler-semaphore saturation path had the identical defect, and that
one needs no quota burst to fire.

**Solution:** NIP-01 gives each request type its own acknowledgement
channel, and a rejection is only actionable on the same one. Reject a
REQ with `CLOSED`, an EVENT with `OK(id, false, reason)`, and fall back
to `NOTICE` only where no per-request correlation exists. COUNT refusals
now also use `CLOSED(query_id, reason)` per NIP-45, covering both quota
admission and handler saturation (added in
`cd12c93804b87a24b61075dfd171dc471a0a527f`).

Reason strings are unchanged, so the `rate-limited:` prefix and `retry
in {N}s` hint that existing client gates parse keep working (desktop
`parseRateLimitHint`, mobile `RelayRateLimitGate`, buzz-acp
`set_rate_limit_gate`). Only the frame *type* changes, so
`docs/multi-tenant-relay.md` L7 stays satisfied.

Two notes on how this landed, both worth a reviewer's attention:

1. **A survived mutation became a design change.**
`send_admission_result` originally took a `RejectionTarget` parameter,
and reverting the *second* call site (the per-minute message quota)
survived the whole suite — with Redis unreachable the first quota check
short-circuits, so that line is unreachable in test. Rather than test
around it, the parameter is gone: the target is derived from the frame,
so no call site can name the wrong channel.

2. **The relay fix would have caused a client regression on its own.**
Gate arming lived only in the NOTICE branch. Once rejections arrive as
`OK:false`, `handleOk` failed the send without ever backing off — the
client would retry straight into the same quota. Desktop and Mobile now
arm on a `rate-limited:` OK rejection. ACP was subsequently fixed in
`3b06dd32493596ec650f20abf8805791c50fdc24`: it arms the gate and
re-parks only the refused observer frame, preserving other in-flight
frames. Desktop gets `activateRateLimitIfSignalled` as the single owner
of that prefix test, called from both `handleOk` and the NOTICE branch.

<summary>File changes</summary>

**crates/buzz-relay/src/rejection.rs** (new)
Owns the admission-rejection concern: `RejectionTarget`,
`rejection_target_for`, `request_rejection_message`,
`send_admission_result`, and `enforce_ws_admission`, moved out of
`connection.rs`. Six tests, two of which drive the real
`enforce_ws_admission` against a real `AppState`.

**crates/buzz-relay/src/connection.rs**
Fix the EVENT handler-semaphore rejection to correlate to the event id;
delegate admission to the new module. Add two tests that drive the real
`handle_text_message` with every handler permit held. Down from 1319 to
1116 lines.

**crates/buzz-relay/src/state.rs**
Widen the existing `test_state` helper to `pub(crate)` so the rejection
tests reuse it rather than adding a ninth copy of `AppState`
construction.

**desktop/src/shared/api/relayRateLimitGate.ts**
Add `activateRateLimitIfSignalled` — one owner for the `rate-limited:`
prefix test, since three inbound frame types now carry it.

**desktop/src/shared/api/relayClientSession.ts**
Arm the gate on a rate-limited OK rejection; route the NOTICE branch
through the same helper. Net zero lines, which keeps this
already-oversized file within the differential ratchet.

**desktop/src/shared/api/relayClientPublishRejection.test.mjs** (new)
Four tests against the real `RelayClient`: a rate-limited OK settles the
pending publish and arms the gate; an ordinary rejection does not arm
it; an accepted OK still resolves.

**mobile/lib/shared/relay/relay_session.dart**
Arm the gate in `_handleOk` for a rate-limited rejection.

**mobile/test/shared/relay/relay_session_test.dart**
Two tests driving the real `publish` + `debugHandleMessage` path.

<summary>Validation</summary>

**Mutation-tested — 5 mutations, all now killed.** Each production call
site was reverted to the defective behaviour to confirm a test fails.
This caught two false-negative tests:

| # | Mutation | Result |
|---|----------|--------|
| 1 | `rejection_target_for`: EVENT → `Connection` | 4 tests fail |
| 2 | EVENT handler-semaphore call site → bare NOTICE | **survived at
first** |
| 3 | per-minute quota call site → `Connection` | **survived**; fixed by
removing the parameter |
| 4 | desktop `handleOk` gate arming removed | 1 test fails |
| 5 | mobile `_handleOk` gate arming removed | 1 test fails |

Mutation 2 is the lesson: my first saturation test called
`request_rejection_message` directly, so reverting the real call site
inside the `match` arm left it green. It now drives
`handle_text_message` itself and dies on that mutation.

- `cargo test -p buzz-relay` — 928 passed, 1 failed:
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo`,
**pre-existing**, reproduced with all changes stashed at `4dd4d73de`.
- `cd desktop && npm test` — 5721 passed, 0 failed (full suite).
- `cd mobile && flutter test` — 1876 passed, 0 failed (full suite).
- `just fmt-check`, `just clippy`, `just desktop-check`, `just
mobile-check`, `just file-size-check` — clean. Desktop's 5 biome
warnings are pre-existing (reproduced with changes stashed).
- All 9 pre-push lanes green, including `rust-tests` and
`desktop-tauri-checks`.

**Not verified:** not reproduced end-to-end against a live relay under a
forced quota burst. The causal chain is source-proven and
mutation-proven at the frame level; the ~25s attribution follows from
`PUBLISH_TIMEOUT_MS` but is not directly measured. A packaged-build
click-through would close that gap.

Related work: #6957 bounds Desktop HTTP event submission, but safe
retained-operation recovery after exhausted/ambiguous outcomes remains
unfinished. #6998 is the separately reviewable Desktop
readiness/duplicate-subscription slice. Neither is claimed to complete
native before/after startup-send validation.

## Current review disposition (2026-08-28)

The [review on
`cd12c938`](https://github.com/block/buzz/pull/6961#pullrequestreview-5052902510)
identified ACP's missing rate-limited-OK handling. Commit
`3b06dd32493596ec650f20abf8805791c50fdc24` fixes gate arming, re-parking
the specifically refused observer frame, and the stale NOTICE comment.
Two regressions drive the real frame dispatcher. See [the implementation
and validation
response](https://github.com/block/buzz/pull/6961#issuecomment-5455032054).

The Mobile generation-check inline thread is resolved: its `async
publish` returns a failed Future when superseded; it does not throw
synchronously at invocation. No further production change was indicated
by that comment.

The validation counts above describe the original slice, not a new
rerun. At `3b06dd324`, the current GitHub check rollup has successful
completed test/build checks (non-applicable jobs skipped). The
security-review comment still requires review for the current base/head
range; do not read a green authorization job as a completed security
review. Approval and merge remain human decisions.
