ac5a18697c feat(desktop): add persistent Bestie experience (#7223)
## Summary

- add a persistent, community-scoped Bestie designation for local
managed agents
- surface the designated agent in the sidebar, agent library, profile
actions, message toolbar, and draggable floating shortcut
- bloom the floating shortcut into a lightweight compact composer that
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

replacements. Extracted from

To check manually, open an old message from stopped A while same-persona

#### Evidence and limitations

**5,793 desktop tests**, **56 profile/archive browser cases**,

historical-message regression fails on unchanged main by opening B
instead of A. [Published-head CI

The [advisory security
check](https://github.com/block/buzz/actions/runs/33422240973) timed out
without a result; it is not a passing check. No availability,
cloud-marker, discovery or mention-routing change is included. These
screenshots do not establish remote delivery, agent execution or

#### Security authorization history (audit, not clearance)

The [security

cancelled after the previously reported timeout; it did not produce a
completed security review. Latest exact-head Run/Post Codex jobs are
skipped, not security approval. Historical comments remain available at
their original links; consolidating their audit here does not withdraw
authorization or clear the gate. An authorized security workflow owner
must arrange the missing exact-range result.

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.

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.

<details>
<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.

</details>

<details>
<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

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.

## 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.

00e61eafa9 fix(desktop): surface channel history load failures (#7013)
## Summary

A failed initial channel-history request no longer appears as an
authoritative empty channel. The timeline now shows an announced error
with a Retry action, while cached messages remain visible when a later
refresh fails; successful empty channels continue to use their normal
intro state.

### Related issue

None found.

### Testing

- Full desktop unit suite (`pnpm test`)
- Desktop TypeScript check (`pnpm exec tsc --noEmit`)
- Biome checks for changed files
- Repository file-size ratchet
- Full pre-push desktop checks and tests
- Desktop app launched successfully against local Postgres and Redis for
manual testing

No screenshot is included because the new UI is only shown after a
terminal relay-history failure; the regression test pins the
error/empty/list precedence directly.

8dbc65d9e2 fix(composer): polish automatic mentions (#6956)
**Category:** improvement
**User Impact:** Automatic mentions are easier to turn off and now
behave consistently across conversations, settings, drafts, and repeated
agent mentions.

**Problem:** People found the new automatic mention behavior hard to
control: turning it off in Settings did not reliably affect the
composer, removing a mention could require also disabling the feature,
and root/thread composers could inherit or restore surprising state.
Other reported rough edges included only one of several mentioned agents
becoming automatic, synthetic mentions leaking into drafts, restored
mentions corrupting adjacent text, controls remaining visible in
archived channels, and unclear picker feedback. See the [original
feedback
thread](buzz://message?channel=e62570dd-33ad-42c5-b92b-75f2689f9694&id=c949ec399274fbb0d6633da3f95712e843a67dcada214f63d72f6975b406604b).

**Solution:** Polish the existing feature around the problems people
encountered, keeping automatic mentions controllable and scoped to the
active conversation.

| Reported issue | UX fix |
| --- | --- |
| Turning automatic mentions off in Settings did not reliably update the
composer. | The global setting and composer control stay synchronized,
and disabling the feature does not clear typed text. |
| Removing an automatic mention could require both deleting the mention
and turning off the feature. | Removing or unchecking an agent excludes
that agent for the current conversation, while explicitly re-adding the
agent can restore automatic mention behavior. |
| Root and thread composers could share or restore surprising
selections. | Each root or thread composer keeps its own automatic
audience and restores it when the user returns. A request to enable
automatic mentions only in agent threads was considered; this PR keeps
them available at the channel root but prevents state from leaking
between the two. |
| Mentioning multiple agents could leave only one saved as automatic. |
Multi-agent selections remain represented in the automatic audience and
restored mention chips. |
| Automatic mention prefixes could be saved as if the user typed them. |
Synthetic prefixes stay out of persisted drafts while authored text is
preserved. |
| Restored mentions could lose their separator and corrupt continued
typing. | Restored multi-word mentions retain their trailing space and
place the caret after it. |
| Archived channels showed automatic-mention state beside a disabled
composer. | Disabled composers hide automatic-mention controls while
preserving the draft and restoring state when re-enabled. |
| Confirmation and picker behavior made the feature feel difficult to
inspect or adjust. | Confirmations dismiss with removed agents, remain
open while hovered, and expose the setting before it changes; pin icons,
contrast, scope copy, animation, and keyboard toggling are also
clarified. |
| Agent suggestions and membership state could shift during directory
refreshes. | Suggestions and membership labels stay stable during
refreshes, while send-time authorization still revalidates access. |

## Reproduction Steps

1. Open a channel with at least two available agents and enable
automatic mentions from the composer mention control.
2. Select multiple agents, remove or uncheck one, and confirm subsequent
composer updates keep that agent excluded while the others remain
automatic.
3. Open a thread, choose a different automatic audience there, and
switch between the thread and root composer; confirm each composer
retains only its own choices.
4. Disable automatic mentions and confirm the draft text remains
unchanged while automatic chips and controls show the disabled state;
re-enable the setting and confirm eligible automatic chips return.
5. Delete an automatic mention chip, then explicitly add the agent
again; confirm it immediately returns as an automatic mention without
disturbing spaces or the caret, including for a multi-word name.
6. Reload with a saved draft and confirm implicit automatic mentions
were not persisted as authored draft text.
7. Use the automatic-mention keyboard shortcut and picker repeatedly;
confirm the picker remains open for additional choices and the
highlighted agent toggles in place.

## Validation

Validated at `34d208b47d64a9816f88e10a46bcfd479e917d75` after rebasing
onto `origin/main` (`69096c9a8`):

- Desktop unit tests: 5,731 passed, 0 failed.
- Desktop TypeScript typecheck: passed.
- Desktop E2E build: passed; emitted only existing chunk and
dynamic-import warnings.
- `pnpm check`: exited successfully; 4 warnings and 5 informational
findings are in unrelated files introduced by current main.

## Screenshots/Demos

The behavioral changes are covered by the focused desktop E2E scenarios
above. Screenshots can be attached from the screenshot-producing
automatic-mention E2E after the PR is created.

2c99ee7af5 fix(desktop): resolve bundled sidecar on cheap path and bound login-shell spawns (#6904)
## Why

PR #6330 split agent harness/runtime detection into a cheap (cache-only)
path and a forced (spawning) path. Two regressions followed, both
surfacing as every harness showing "(not installed)" / "CLI missing"
across the agent create/edit picker, Agents > Agent defaults, and
Settings > Agents — blocking agent create/edit until the user clicked
Install in Settings > Agents.

## Root cause

One underlying bug, two victims:

- **Boot false-negative.** The resolve cache is in-memory, so it starts
cold on every launch. `resolve_command_cached` (the cheap path)
consulted only the Buzz-managed shim dirs plus that cold cache, and
`buzz_managed_command_path`'s allowlist structurally excludes
`buzz-agent`. The bundled sidecar could therefore never resolve on the
cheap path until a forced pass warmed the cache, so cheap-path surfaces
rendered all-missing at boot. App setup never warms the cache.
- **"Check again" hang.** `run_in_login_shell` used an untimeouted
`Command::output()`; a wedged login shell froze the whole forced
pipeline, leaving "Check again" spinning forever.

## What

- `resolve_command_cached` now also calls `resolve_workspace_command`,
resolving the bundled sidecar via a filesystem stat (no spawn) — the
same class of work the managed-shim check already performs. `buzz-agent`
can no longer report missing, even inside the boot warm window.
- New `discovery/bounded_command.rs` runs any discovery child under a
hard wall-clock deadline, polling with `try_wait` rather than blocking
on `wait()`. Stdout and stderr are piped to two drain threads whose
buffers share an aggregate `CAPTURE_LIMIT`; a breach fails closed (kill
the tree, return `None`), so a noisy or hostile probe can force neither
unbounded memory nor disk fill. Tree teardown runs on every exit path —
timeout, error, cap breach, *and* success — because a login-shell rc
file or auth CLI can legitimately background a descendant that would
otherwise outlive discovery. Ownership is deliberately asymmetric:
- **Unix:** the child leads its own process group (`process_group(0)`);
teardown is `SIGTERM` → bounded grace → `SIGKILL` on the group. A
descendant that leaves the group (`setsid`/`setpgid`) while holding a
pipe is not owned and may survive one probe, but can never hang or
unbound the helper: the Unix drains read nonblocking and end on
`WouldBlock` once teardown sets the stop flag, so the join returns
promptly without waiting on an escaped writer's EOF.
- **Windows:** the child is spawned `CREATE_SUSPENDED`, assigned to a
kill-on-close Job Object while frozen, then resumed. The job owns the
root before any descendant can exist and is created without breakaway,
so no writer can escape — a hard whole-tree guarantee, and closing the
job reaps the tree even after the root has exited. Any failure to
create, assign, or resume is fail-closed: the child is terminated and
reaped and the spawn returns `None` (discovery treats it as
command-not-found) rather than running unowned.
- Each login-shell candidate is bounded by a 10s timeout via that
helper, falling through to the next candidate on timeout instead of
aborting the resolve. The login-shell path cache is generation-aware: a
probe that loses to a concurrent refresh or lands mid-refresh returns
the authoritative cached value (or re-probes under the new generation)
rather than its own rejected local result, so a losing thread can never
settle the UI with a PATH-missing catalog while the cache holds a fresh
success.
- Warm the ACP runtime catalog once at `AppShell` mount and gate the
cheap-path surfaces on that pass. A module-level boot-warm state (`idle`
→ `pending` → `settled`/`failed`, deduped per launch) lets
`useAcpRuntimesQuery` present a cold catalog as *loading* while the
first forced pass runs and as a *retryable error* (carrying the probe's
real reason) if it fails, instead of blessing "every harness not
installed" as authoritative. A non-empty catalog always wins, so a
revalidation or later failure never blanks a good list; the gate only
overlays once the warm has started, so onboarding (which renders before
the warm) is unaffected. Deduping per launch also fixes the previous
per-remount re-fire.

## Verification

Unix teardown and the drain contract are runtime-proven by
`#[ignore]`-free tests that record a backgrounded descendant's real PID
and assert the helper returns promptly on both the success and timeout
paths without blocking on that writer. The generation-aware login-shell
cache is covered by deterministic tests through a `cfg(test)` injectable
probe seam that assert the function's return value under both
concurrent-refresh interleavings — the losing caller returns the peer's
committed success, and a mid-probe refresh forces a re-probe to the
fresh value. The Windows ownership contract has no CI lane, so
`bounded_command.rs` carries two `#[ignore]`-gated tests (spawn/assign
race, looped; and the timeout path) for a sanctioned run on a Windows
host. The boot-warm gate is covered by unit tests for the pure overlay
and the `startBootWarm` failure → retry → settle lifecycle.

a3730784fc refactor(db): extract domain stores from database runtime (#6987)
## Summary

Finish the remaining database-store extraction tracked by
[TheSentinel454/buzz#2](https://github.com/TheSentinel454/buzz/issues/2)
in one reviewable PR.

This consolidates the previously stacked domain slices after #6782
merged. It preserves the runtime/store boundary established by #6660,
#6668, #6700, and #6782 while separating database runtime infrastructure
from domain-owned persistence:

- `runtime/` owns pool construction and sizing, writer/reader routing,
read sessions and route proofs, transaction infrastructure,
observability primitives, replica fencing, health support, migrations,
and cross-cutting runtime tests.
- `store/` owns domain records, SQL, row parsing, locks and invariants,
`Db` domain methods, focused tests, and logical-operation datastore
spans.
- `lib.rs` remains a 57-line compatibility facade that preserves
existing crate-root paths and `Db` method signatures through re-exports.

Domain coverage includes API tokens, authentication allowlists,
reminders, event queries, threads, reactions, feeds, users and DMs,
push, workflows/runs/approvals, relay membership and invites, product
feedback, moderation/admin moderation, relay admin actions/operators,
git repositories, archived identities, usage, partition maintenance,
deletion, channel membership inherited from merged #6782, and the final
runtime/store layout.

The branch has been rebased onto current `main`. Database changes that
landed there were incorporated rather than overwritten:
`relay_admin_actions.rs` and `relay_operators.rs` now live under
`store/`, their 27 public `Db` wrappers and existing behavior remain
intact, and every wrapper has exactly one fixed-name datastore span.
Concurrent changes to migration, moderation, admin moderation, and error
handling are also retained.

available for review history.

### #17 / #19 acceptance

- Preserves the metric names, fixed labels, transaction/lock timing
boundaries, and privacy/cardinality constraints introduced by #6700.
- Keeps exactly one datastore span per public logical operation,
including the 27 relay-admin wrappers added on `main`.
- Removes `store_ownership.rs`; physical ownership and focused source
guards now enforce the boundary directly.
- Leaves no `impl Db`, domain SQL, focused domain test group, or
datastore span in `lib.rs`.
- Preserves existing public paths such as `buzz_db::channel`,
`buzz_db::event`, and `buzz_db::workflow` through crate-root re-exports
while keeping internal `runtime` and `store` namespaces private.

### Non-goals

- No SQL, schema, locking, transaction, retry, timeout, or
client-visible behavior changes.
- No generic store traits, domain handles, broad `PgExecutor` migration,
new store crate, raw pool accessor, or broader directory reorganization.
- No tracker issues are closed by this PR.

### Risk

The cumulative diff is large but structural. Risk is primarily
module-path, ownership, or conflict-resolution drift. It is mitigated by
preserving public re-exports, comparing the newly moved `main`
implementations to their upstream source, source guards, touched-crate
compilation, PostgreSQL-backed test coverage, and an independent
exact-head review on a separate clean Blox workstation.

### Testing

Author workstation `buzz-tornquist-pr-6987-rebase`, rebased branch
ending at exact head `be24430472d1a87ac5c0d6026c620cd6caea3537`:

- `cargo fmt --all --check`
- `cargo clippy -p buzz-db -p buzz-relay --all-targets -- -D warnings`
- `cargo test -p buzz-db --lib` — 113 passed, 240 PostgreSQL tests
intentionally ignored
- `cargo test -p buzz-db --test observability_source` — 2 passed
- PostgreSQL-backed `buzz-db` coverage under native PostgreSQL — 235
passed in the shared serial run; the five shared-state/config-sensitive
cases passed as isolated reruns against fresh schemas, including the two
owner-limit tests with their fixture's
`BUZZ_MAX_COMMUNITIES_PER_OWNER=3`
- `cargo test -p buzz-relay --lib -- --test-threads=1` under native
PostgreSQL/Redis — 991 passed; the three current-month
partition-sensitive identity-archive cases passed after provisioning the
August 2026 test partition; 87 infrastructure-marked tests remained
ignored
- Source/diff guards — relay-admin implementation bodies match current
`main`; all 27 public wrapper signatures are retained; exactly one
datastore span wraps each wrapper; `lib.rs` has zero `impl Db` blocks
and zero datastore spans; no duplicate top-level relay-admin modules or
`store_ownership.rs`; `error.rs` matches current `main`

Independent clean review workstation `buzz-tornquist-pr-6987-review`,
detached at exact head `be24430472d1a87ac5c0d6026c620cd6caea3537`:

- `cargo fmt --all --check`
- `cargo clippy -p buzz-db -p buzz-relay --all-targets -- -D warnings`
- `cargo test -p buzz-db --lib` — 113 passed, 240 ignored
- `cargo test -p buzz-db --test observability_source` — 2 passed
- Exact-head ownership/re-export/instrumentation audit — no remaining
actionable findings

2f66ee24a0 feat(desktop): add team sharing to community catalog (#3995)
Stack: [#5112](https://github.com/block/buzz/pull/5112) → this PR

Stacks on the team catalog backend PR (#5112). Contains the `desktop/**`
changes that turn the add-agent surface into a single Community Catalog
browsing both shared agents and shared teams.

## Owner catalog sync pipeline

`usePersonaSync.ts` gains a hydration pipeline in `startPersonaSync` so
a fresh device that comes online after another already published the
owner's 30178 catalog head reconstructs the complete state without
falsely retracting it. The owner's
persona/team/managed-agent/30178/deletion history is backfilled up front
(a live-only subscription gets no history — reconnect-replay's
since-cursor is undefined until the first live event), then a live
subscription takes over.

Four properties keep a fresh sync from purging the owner's valid shared
head:

- **Paged backfill with a safe termination guarantee.** The relay serves
each REQ newest-first and clamps `limit` to its advertised `max_limit`,
so a large owner's history overflows one page — a newer 30178/30176
could return in-page while an older required 30175 constituent falls
beyond it. `fetchOwnerHistoryToExhaustion` pages the full window with
the `until` time cursor (the only cursor the WS REQ filter exposes; the
DB `before_id` keyset is REST-only), deduping the inclusive-boundary
rows. A short page terminates normally. A full page whose oldest event
cannot advance the time-only cursor is a **dense boundary** — more than
one page of events share one `created_at` second, which the WS filter
has no `(created_at, id)` cursor to escape — and raises
`PersonaHistoryDenseBoundaryError` rather than silently completing as if
the history were exhausted and dropping the older constituents behind
it.
- **Constituents-before-catalog ordering.** Over the complete batch,
`orderCatalogHeadsLast` stably defers every 30178 head past its
30175/30176 constituents. Reconciling a 30178 head before its personas
hydrate makes the inbound team refresh fail member resolution and queue
a dominating false tombstone; deferring the heads guarantees the
constituents are all applied first, while newest-wins order within every
other coordinate is untouched.
- **Hydration boundary for concurrent live events.** The backfill fetch
and the live subscription start concurrently into one reconcile chain. A
live or replayed 30178 that arrives before the backfill reconciles its
constituents would reproduce the same false-tombstone purge, so live
events are buffered until the ordered backfill is dispatched and then
drained in arrival order. Steady-state live events (after hydration
completes) reconcile immediately.
- **Explicit backfill failure policy.** A transient history-fetch
rejection is retried with bounded backoff. When backfill cannot complete
— retries exhausted, or a deterministic dense boundary — the pipeline
enters a **degraded-live** state rather than leaving the subscription
permanently inert with live events accumulating in the buffer: the
hydration boundary still opens so buffered and future live events keep
reconciling, but the whole catalog dependency set is dropped — the 30178
head, its 30175/30176 constituents, and any kind-5 deletion carrying a
dependency-targeting `a` tag (classified by scanning *all* `a` tags,
matching the backend's deletion router, which `find_map`s across every
tag and routes the first signer-owned coordinate — so a malformed or
foreign first `a` tag ahead of an owned 30176 cannot slip a destructive
deletion through) — because backfill never fully hydrated the owner's
constituents. Dropping only the 30178 head is not enough: the backend
refreshes the catalog head after every team/persona save, and live
delivery is newest-first, so a 30176 edit that adds a *new* member would
reach the backend before that member's 30175 and falsely tombstone a
witness-holding device's valid team. Holding the prior hydrated run's
constituents on disk only proves the *old* revision is resolvable — it
says nothing about a new member — which is why the entire dependency set
is held rather than just the head. 30177 managed-agent runtime policy
stays live (it drives no catalog refresh). A degraded device stays stale
on team/persona edits until it self-heals on the next effect re-run
(restart, or an identity/community switch) — the correct trade against
destroying valid shared state.

## Data layer

Relay paging, signature verification, NIP-33 head selection, and
untrusted-content parsing for the kind `30178` team catalog live
natively in the `fetch_team_catalog` Tauri command (`team_catalog.rs`),
structurally mirroring `fetch_persona_catalog` (`persona_catalog.rs`). A
catalog refresh crosses IPC once and never verifies a signature on the
webview thread. `teamCatalogRelay.ts` is now a thin presentation and
local-linkage layer over the verified projection — it shapes entries for
display and links each to a local team, and never parses or verifies.

Parsing is all-or-nothing, identical to the add-time re-fetch in
`add_team_from_catalog`: a team with any invalid member fails to parse
and the publication is dropped from the catalog, matching persona
behavior. **Behavior delta:** the previously reviewed partial-render of
invalid-member teams — a warning banner on an entry that could never be
added — is removed. Invalid publications are dropped entirely rather
than surfaced as un-addable.

## Hooks

`useTeamCatalogRelay.ts` mirrors the persona catalog hook: a
community-keyed query over `fetch_team_catalog`, live invalidation on
kind `30178`, share/unshare, and add-from-catalog (which invalidates
both the teams and personas stores, since adopting a team copies its
members as local personas).

## CommunityCatalogDialog

Single unified surface replacing the former separate dialogs. Agents and
Teams appear as labeled sections with type-tagged selection and a
teams-preferred launch. `TeamsSection`'s discover entry and the
new-agent card both open this one dialog. `PersonaCatalogDialog.tsx` is
removed; persona browsing now lives inside the unified dialog.

## TeamShareDialog

Publishes and unshares team catalog entries via `set_team_shared`.

## e2e + screenshots

`team-catalog.spec.ts` covers the browse + adopt flow;
`team-catalog-screenshots.spec.ts` produces the pixel-regression set.
`e2eBridge.ts` gains `mockTeamCatalogPublications`, which mirrors the
native command's head selection and shared gate and performs only a
shallow `v`/`name`/`members`-array shape check; per-member validation
stays in the Rust command.

## Follow-ups

None. The shared agent-definition text-safety policy
(Unicode-control/bidi/zero-width rejection) already covers the team
surface: #5112's `validate_team_catalog_content` chokepoint gates every
field delivered verbatim to the harness on both the publish and adopt
paths, and this PR's parse layer consumes that verified projection
rather than re-validating on the webview thread.

a89f5df4c5 fix(desktop): complete project empty and context states (#6980)
## Summary

First-time project users can now create a project directly from the
empty state instead of reaching a dead end. The right-side project
context also uses the intended Activity label and aligns its first row
with the channel header.

The populated and empty project views share one creation flow, so
navigation, success feedback, and compatibility warnings remain
consistent.

Related: #6939

### Testing

- Desktop check, TypeScript typecheck, and repository file-size gate
- 10 focused project overview context unit tests
- E2E-mode build and 3 focused Playwright scenarios covering empty-state
creation, right-sidebar alignment, and Activity context

b49675894b fix(desktop): resolve exact typed mentions on space (#6862)
## Summary

- Convert an exact, authorized manually typed `@Name` into the existing
visual mention chip when plain Space is pressed.
- Reuse autocomplete selection so outbound mention pubkeys, agent
styling, and address behavior remain identical.
- Preserve partial names, longer multi-word names, duplicate-name
ranking, modifier keys, and IME composition.

9733863516 perf(desktop): restore project context during startup (#6939)
## Summary
Project channels previously appeared as ordinary channels until the
community-wide project enumeration completed, delaying the contextual
right rail most noticeably on larger relays.

- Restore the last fully validated, relay-and-identity-scoped project
collection immediately while keeping live relay data authoritative.
- Resolve the active channel's project home through scoped
`#buzz-channel` queries instead of waiting for the complete project
scan.
- Keep snapshots aligned with community removal and relay reconnect
invalidation.

### Related issue
None found.

### Testing
- Pre-push `file-size-check`, `desktop-check`, `desktop-typecheck`, and
`desktop-test`
- Project enumeration, snapshot persistence, and relay invalidation unit
coverage
- Targeted Playwright scenario: project sidebar rows open the home
channel and nest extra channels

No numeric startup benchmark was captured; this draft validates the
cache and scoped-query behavior while leaving timing measurement for
review.

350caf1de3 fix(desktop): lift right auxiliary pane above shared header backdrop (#6966)
## Summary

The sidebar close (`X`) and `Edit` controls disappeared for in-channel
side panels on `main`. They stayed clickable but were visually washed
out.

[#6901](https://github.com/block/buzz/pull/6901) added `isolate` to
`RightAuxiliaryPane` so project workspace sheets slide over an open
thread cleanly. The pane carries no `z-index`, so isolating it makes the
whole pane subtree paint at stacking level 0 — below the channel's
sibling `z-30` shared-header backdrop in split layout. That translucent
blur strip then washes out the pane's own `z-40` header chrome, where
`X`/`Edit` live. The backdrop is `pointer-events-none`, so the controls
remained clickable but invisible (matching the reported videos).
Threads, channel settings, and in-channel agent panels all route through
this wrapper, so all three were affected; the standalone Agents-nav
panel does not render inside `ChannelPane`, so it had no backdrop and
worked.

## Fix

Add `z-31` to the pane's `aside` — above the `z-30` backdrop, still
below the `z-41` thread drawer/sheet overlays. `isolate` stays, so
#6901's sheet-over-thread layering is preserved and both behaviors
coexist.

## Regression coverage

`tests/e2e/auxiliary-pane-close-visibility.spec.ts` opens a split-layout
thread from inside a channel and asserts the pane establishes its
`isolate` stacking context and that its `z-index` outranks the
shared-header backdrop. It fails on the pre-fix tree (pane `z-index` is
`auto`) and passes with `z-31`. #6901's `project workspace sheet stays
independent from an open thread` spec still passes.

a7c7414a7f feat(desktop): implement 30178 team catalog backend (#5112)
Implements the Rust/backend half of 30178 team catalog sharing on the
community catalog. No TS callers yet — this is PR 1 of 2;
[#3995](https://github.com/block/buzz/pull/3995) (stacked here) adds the
parse layer, hooks, `CommunityCatalogDialog`, and e2e tests.

## What this adds

**Projection builder** (`team_catalog.rs`):
`build_team_catalog_event/content` produces a 30178 event from a team +
member definitions. Size contracts: 192 KiB total ceiling, per-field
bounds (name 256 B, text 4 KiB, system-prompt 16 KiB, avatar URL 32 KiB
for projection fields; https URLs additionally validated at 2,048
bytes). Avatar handling: oversized raster data URLs downscaled to fit;
oversized built-in avatars silently omitted; oversized https URLs
rejected with a named error.

**Share/unshare/tombstone** (`commands/teams/pending.rs`):
`prepare_team_publication_at` retains a signed 30178 head for the flush
loop; share state is relay-scoped (one community can share while another
does not). `refresh_or_retract_shared_head_at` rebuilds or tombstones
the head immediately on team/member edit — no stale publication until
the next boot. Both the 30178 catalog and 30176 team tombstones are
signed with a `created_at` that strictly dominates the retained head's
(read inside the delete transaction), so a future-dated head cannot
survive its own deletion under the relay's `created_at <=` soft-delete
gate.

**Serialized-publisher share command** (`commands/teams/sharing.rs`,
`managed_agents/persona_events.rs`): `set_team_shared` publishes the
retained head through `flush_pending_events_at` rather than submitting
the prepared event directly. A direct submit ran outside
`managed_agents_store_lock` and raced `delete_team`: the delete
atomically purges the head's retained row and enqueues a newer 30178
tombstone in one transaction, and a delayed direct submit could land the
old shared head *after* that tombstone. Because 30178 replacement has no
deletion watermark, the deleted team would go publicly live again.
Routing through the flush is necessary but not sufficient, because the
flush is not itself a single publisher: several call sites (the 30s
sweep, this share toggle, managed-policy updates) invoke it
concurrently, and each invocation has an await gap between its per-row
re-read and its relay POST. A second flush could publish the tombstone
in that gap while an earlier flush's delayed POST lands the just-purged
head after it. The flush now acquires a per-scope publisher mutex —
keyed by the canonical retention `db_path`, which already *is* the
durable scope identity (hashed normalized relay URL + owner pubkey) —
and holds it across its entire invocation: snapshot, per-row re-read,
POST, and `mark_synced`. Serialized-per-scope flush ⟹ within one scope
the only interleavings are head-before-tombstone (the head lands first,
then is dominated by the later tombstone) or purged-row-skip (the delete
committed first, so the re-read skips the head) — a purged head can
never publish after its tombstone. The lock is a
`LazyLock<Mutex<HashMap<PathBuf, Arc<tokio::sync::Mutex<()>>>>>` static
rather than an `AppState` field: it keeps the invariant at its
acquisition site and out of the size-ratcheted `app_state.rs`
(precedent: `agent_models_databricks.rs`'s `AUTH_GATE`), and the
std-mutex map guard is released before the async guard is awaited so it
never spans an await point. Keying per scope — rather than one
process-global lock — means a stalled or hostile relay in one community
can no longer block publication in every other community, and each
per-row submit is additionally wrapped in a
`tokio::time::timeout(PUBLISH_TIMEOUT = 60s)`:
`submit_signed_event_at_with_keys` first waits on the process-wide
admission gate (up to 300s on a 429) and then POSTs on the app-wide
`http_client`, which leaves reqwest's connect/read/total timeouts unset,
so a relay that accepts the connection and never finishes the response
would otherwise pin the lock forever. A timeout takes the same
`Err`/`continue` path as a relay rejection — the row stays pending for
the next 30s sweep and a timed-out tombstone keeps its replacement
deferred this pass — so a live admission gate now surfaces as
timeout-pending rather than a held lock, the correct durable behavior
since the sweep retries. `publicationStatus` (Published/Queued) is
derived by re-reading the retained row's pending flag after the flush.
The previously-unused `relayMessage` field is dropped from
`SetTeamSharedResult`: the flush loop swallows every per-event relay
rejection to its own log and only surfaces local DB faults (which the
status re-read already propagates), so the field was permanently `null`
on this path. #3995's `tauriTeams.ts` mapping and `useTeamActions.ts`
log branch drop with it.

**Domination-aware flush** (`managed_agents/persona_events.rs`): a
strictly-dominating tombstone can be signed past the relay's ingest
acceptance window (`MAX_TIMESTAMP_DRIFT_SECS`, ±900s from server time).
Republishing such a byte-frozen event verbatim from the pending queue
lets it age out of the window and be rejected forever, stranding the
head live. The flush loop is now domination-aware for every retained
kind:5 (covering both 30176 and 30178). For a pending tombstone with
floor `f` (= the retained row's own `created_at`):

- `f <= now` → re-date and re-sign at `now` (mirrors the existing
archive-request re-sign branch; `mark_synced` stays keyed to the
untouched retained row, so a re-date can't mask a concurrent edit),
- `now < f <= now + 900` → publish verbatim at `f`, inside the window,
- `f > now + 900` → skip the sweep; the event stays pending and its
replacement keeps deferring (via `failed_tombstones`) so out-of-order
retraction remains impossible, converging as the wall clock advances.

No path emits an event the gate rejects, and a boundary reject
self-heals through the submit-error requeue. Durable across offline gaps
of any length.

**Atomic adopt** (`commands/teams/adopt/`): `add_team_from_catalog`
re-fetches and signature-verifies the head from the relay, then plans
and commits a multi-entity add across two store writes with byte-exact
rollback on any failure (crash window between writes explicitly
retained). `plan_add` resolves full member provenance (owner, d-tag,
member-key, projection-hash), reuses a recipient's own local built-in
only when the published slug matches and the reuse hint's
`projection_hash` — recomputed from the member's own embedded fields at
the parse boundary and rejected on mismatch — equals
(case-insensitively, matching the boundary's hex tolerance) the
recipient's local built-in hash, and reactivates deactivated copies on
re-add. Because the boundary already proves the hint hash describes the
reviewed projection, a publisher cannot pair a real built-in's slug +
hash with arbitrary reviewed fields to make adoption install the
recipient's built-in in place of what was shown. `commit_stores`
snapshots both stores before writing and restores them on failure. The
commit and the retention enqueue are sequenced inside
`commit_and_enqueue`, the sole route to a durable adoption commit: once
the store write succeeds it enqueues a pending 30175 for every member
copy the add wrote or reactivated and a pending 30176 for the team, so a
crash before the next boot reconcile cannot lose the only adopted copy.
A provenance match on an already-active copy is retained too (not just a
reactivation): a recovery retry after a crash between the persona write
and post-commit retention finds the copy active with no 30175 row, and
`plan_add` short-circuits once the team row exists, so this reuse branch
is the only place that retry can re-enqueue the orphaned member head.
Retaining unconditionally is conservative, not exact — an active copy
still referenced by a standalone managed agent can already hold a live
head, and re-retaining only bumps it monotonically; reused built-ins are
handled separately and never reach this branch. A byte-identical reused
built-in and an idempotent replay write nothing and enqueue nothing; a
failed commit propagates and enqueues nothing. Enqueue is best-effort
per row (the boot reconcile is the backstop). The frontend refreshes via
the `useAddTeamFromCatalogMutation` query invalidation in #3995, so no
`agents-data-changed` emit is needed here.

**Startup reconcile** (`event_sync.rs`):
`reconcile_team_catalog_heads_at` walks all retained 30178 heads at
boot: republishes heads whose content changed, tombstones heads whose
team or member was deleted, skips unshared heads and unchanged content.
Multi-team continuation — all shared teams processed in one pass.

**Cross-device catalog retention** (`commands/personas/inbound.rs`):
both recovery paths above — the boot reconcile worklist and the
interactive `refresh_or_retract_shared_head_at` — key off a retained
30178 row and guard-return without one. A second device therefore never
retained the owner's own catalog head published from another device, so
its later edit or delete could never supersede or retract that
discoverable head. The inbound reconcile now retains an inbound 30178
head as this device's publication witness through
`retain_inbound_catalog_witness`, a self-gating dispatcher invoked
unconditionally on the production non-deletion path: newest-wins via
`retain_inbound_event`, arrival-scoped, no local JSON store, and
deliberately **no** refresh or republish on arrival — a 30178 arrival is
either this device's own echo or the other device's publication, and
rebuilding on either would make two devices ping-pong identical heads.
Retention advances the witness and stops. The tombstone router accepts a
kind:5 covering a 30178 coordinate, so an inbound deletion purges the
retained head on the receiving device (the covered-head purge already
happens inside `commit_inbound_tombstone_with_store`; a 30178 head has
no local record to remove). After a successful inbound persona/team
upsert, this device refreshes the affected shared heads so the community
catalog tracks the inbound edit (persona edit → every team whose
resolved members include it, resolving the local persona `id` by d-tag;
team edit → that team's head); after an inbound tombstone, a team
deletion retracts its 30178 coordinate and a persona deletion refreshes
the teams that listed it. The refresh is idempotent across devices:
`refresh_or_retract_shared_head_at` skips the publish when the rebuilt
projection is byte-identical to the retained head and still shared, so
the editing device's own published head triggers no churn republish on
the receiving device.

**Executable-text concealment gate** (`team_catalog.rs`,
`definition_validation.rs`): `validate_team_catalog_content` — the
single chokepoint both the publish builder
(`build_team_catalog_content`) and the adopt parser
(`team_catalog_content_from_event`) funnel through — now rejects
invisible, default-ignorable, and bidirectional-override characters
(e.g. U+200B, U+2066, U+202E) in every field delivered verbatim to the
ACP harness or rendered as reviewed identity in the catalog UI. This is
the same invariant the persona catalog already enforces at its own parse
boundary (`persona_catalog::parse_agent`); the 30178 boundary was the
outlier. Member `display_name` + `system_prompt` go through
`validate_agent_definition_text` per member (exact parity with
`parse_agent`: display-name rule with no layout controls, prompt rule
allowing `\n`/`\t`); `name_pool` entries take the display-name rule
since they are minted verbatim as instance display names; team
`instructions` take the visible-text rule with layout controls allowed,
since they reach `BUZZ_ACP_TEAM_INSTRUCTIONS` multiline. The team `name`
takes the display-name rule (no layout controls) and the `description`
takes the visible-text rule with layout controls allowed, since both are
rendered verbatim in the catalog UI as reviewed identity.
`validate_visible_text` is exposed `pub(crate)` from
`definition_validation.rs` and re-exported via `managed_agents`. A
signed, shared, current head can no longer smuggle concealed control
characters into executable configuration or reviewed catalog text
through either the publish or the adopt path; emoji (VS16/ZWJ) names and
multiline instructions still pass.

**Types**: `TeamRecord` and `AgentDefinition` extended with `shared`,
`catalog_source`, `team_catalog_source` fields. All commands registered
in `lib.rs`.

## Tests

- `team_catalog/tests.rs`: projection, size contracts, member-key
stability, tombstone rollback, fixture matrix
- `adopt/tests.rs`: head verification, store planning, provenance,
rollback
- `team_catalog/tests/concealment.rs`: the chokepoint rejects
default-ignorable (U+200B) and bidi controls (U+2066, U+202E) in member
`display_name`, `system_prompt`, `name_pool`, team `instructions`, and
the team `name`/`description`, on both the publish and adopt paths; an
emoji-bearing display name and multiline instructions still pass, so no
legitimate team becomes unshareable
- `team_catalog/tests/reuse_hint.rs`: a member pairing a real built-in's
slug with that built-in's genuine `projection_hash` but carrying
unrelated reviewed fields is rejected at the parse boundary, so adoption
can never substitute the recipient's built-in for the reviewed
projection; an honestly-stamped built-in reuse hint (including an
uppercase form of its true hash) still passes the boundary. Removing the
boundary recompute lets the tampered member validate, proving the test
discriminates the substitution class
- `adopt/tests/reuse.rs`: `reusable_builtin` reuses a local built-in for
an exact-match hint (one record, no copy), reuses it just the same when
the genuine hash is uppercased (case-insensitive, matching the boundary
— one record, not two), and falls through to an authoritative embedded
copy when the hash does not match. Comparing the hash case-sensitively
turns the uppercase case red (two records instead of one reused)
- `adopt/tests/concealment.rs`: a signed, shared, current head carrying
a bidi override drives the `add_verified_team` sequence (verify+parse →
`plan_add` → `commit_and_enqueue`) through real temp stores and a real
retention scope, asserting the head is rejected AND the personas store,
teams store, and retention rows are all left byte-unchanged. Stripping
the concealment call at the chokepoint turns it red — the parse then
succeeds and both stores are written, proving the test discriminates a
validate-after-write regression, not just an error return
- `adopt/tests/retention.rs`: adoption drives `commit_and_enqueue`
through a spy commit + a real temp-dir retention scope and asserts
persisted pending rows — commits-then-enqueues (30175 per minted member
+ 30176 team), a failed commit enqueues nothing, an idempotent replay
skips both the commit and the enqueue, a reused built-in retains only
the team, a reactivated copy is re-retained, and a partial-commit crash
recovery (active member copy with no retention row, team row absent)
re-enqueues the orphaned member's 30175. Deleting the enqueue inside the
seam turns these red — the wiring, not just the helper, is protected
- `sharing/tests.rs`: publish/queue lifecycle plus three concurrency
gate tests. (a)
`concurrent_flushes_never_land_the_head_after_its_tombstone` prepares a
share, runs a concurrent delete's purge+tombstone, flushes the tombstone
to a recording relay, then releases the delayed share and asserts the
purged 30178 head is never published after its tombstone and no pending
row survives (removing the lock turns it red — the relay sees the
resurrected head after the tombstone). (b)
`a_stalled_scope_does_not_block_publication_in_another_scope` pins one
scope's flush mid-POST on a stalled relay and runs a second scope's
flush to completion, asserting it publishes without waiting
(re-globalizing the key turns it red). (c)
`a_stalled_relay_releases_the_publisher_lock_within_the_bound` proves a
never-completing POST returns within `PUBLISH_TIMEOUT`, leaves the row
pending, and releases the lock so a subsequent same-scope flush proceeds
(removing the timeout turns it red).
`test_relay_rejection_stays_durably_queued` asserts queued +
still-pending rather than a relay-message string, matching the
flush-routed contract where the rejection text is no longer surfaced
- `pending/tests.rs`: share/unshare/tombstone lifecycle, edit
refresh/retract, tombstone timestamp domination, typed outcomes,
cross-device catalog convergence — device B retains device A's inbound
head then supersedes it on a member edit and tombstones the coordinate
on a delete, a byte-identical rebuild is a no-op (`Noop`, `created_at`
untouched), and an inbound retention alone queues no outbound publish
(the no-ping-pong guard). Neutralizing the inbound retention leg turns
the supersede/tombstone regressions red — B stays blind (`Noop`, no
dominating tombstone) — proving they discriminate the load-bearing leg
- `catalog_reconcile_tests.rs`: a signed kind:30178 head is driven
through the real production entrypoint
`reconcile_inbound_persona_event_blocking` over a `MockRuntime`
`AppHandle` (retention scope resolved from the handle's `app_data_dir`
under an overridden `$HOME`/`$XDG_DATA_HOME`), asserting the arrival
witness is retained at the owner coordinate with `pending_sync=false`,
stored verbatim, and no outbound publish is queued. An early return for
`KIND_TEAM_CATALOG` immediately before the production
`retain_inbound_catalog_witness` invocation turns it red, proving the
seam under test is the production dispatch path and not a test-only shim
- `pending/tests/gate.rs`: flush driven through a stub relay that logs
every `POST /events` with its accept/reject status and enforces the real
±900s ingest gate, for both 30176 and 30178 — within-window
publish+dominate; beyond-window stays-pending with **zero POSTs** (the
gate never receives a rejectable event); and the delayed/offline-retry
case where a tombstone signed strictly past a then-future head has aged
more than 900s into the past, so flush must re-date to `now` to publish.
The reversal check — restore the byte-frozen replay in
`persona_events.rs` and the delayed-retry and zero-POST assertions go
red — is what proves the suite discriminates the fix from the rejected
implementation
- `teams/tests.rs`: 30176 tombstone timestamp domination and no-head
fallback
- `event_sync_team_catalog_tests.rs`: reconcile scenarios including
multi-head continuation
- 26 shared JSON parity fixtures
(`tests/fixtures/team_catalog_content/`) consumed by both this PR's Rust
tests and #3995's TS tests

## Durable ordering, deletion reconcile, and relay-contract alignment

The catalog paths above sit on the shared inbound/deletion retention
seam. This PR makes that seam's ordering structural rather than
conventional, adds a negative-side (deletion) counterpart to the
existing positive-side boot backstop, and aligns inbound resolution with
the relay's actual soft-delete and NIP-33 winner rules.

**Preflight-then-commit (`commit_inbound_with_store`,
`commands/personas/inbound.rs` + `retention.rs`).** A named primitive
runs the fallible store mutation first and advances the durable
retention head only on success; an event that loses preflight returns
`Skipped` without touching the store. The persona/team upsert arms and
the inbound kind:5 removal path all route through it, so no inbound arm
can advance the head ahead of the store write it represents. The
managed-agent arm keeps its own preflight (its runtime transition must
not run for a skipped event) and still advances the head only after
`save_managed_agents`.

**Atomic + monotonic tombstone helpers (30175 / 30176 / 30177).** The
three ordinary tombstone helpers (`commands/personas/pending.rs`,
`commands/agents_pending.rs`, `commands/teams/mod.rs`) each read the
prior head, sign, delete, and retain inside one `BEGIN IMMEDIATE`
transaction, and sign the kind:5 with a `created_at` that strictly
dominates the prior head (`monotonic_created_at(prior_head)`). This
mirrors the 30178 `tombstone_team_catalog_coordinate` precedent. The
three siblings deliberately duplicate the `BEGIN IMMEDIATE` shape rather
than sharing a helper this round — the shared-helper consolidation is
deferred to the persona-tombstone follow-up PR where the flush-replay
class already lives.

**Deletion reconcile (`event_sync.rs`, negative-side counterpart of the
positive-side boot backstop).** The positive side already reconstructs
missing retained heads at boot from surviving disk records. Deletion is
the asymmetric gap: an atomic tombstone helper preserves the head on
failure, but boot reconcile enumerated disk records — deletion already
removed them — so an orphan retained head was never tombstoned. The
deletion reconcile enumerates retained 30175/30176 heads and tombstones
only genuine orphans (a retained head with no matching disk record),
routing through the now-atomic helpers. It reconciles only against a
successfully parsed store: a truncated, malformed, or wrong-shape JSON
store fails loudly (never triggers a tombstone); a missing file is
treated as empty. Managed agents (30177) are excluded by design: their
inbound sync retains a head *without* minting a local disk record
(agents carry device-local secrets that can't come from a relay event),
so a retained 30177 head with no matching record is the normal
cross-device state for every agent created on another device — not a
lost deletion. Sweeping it would tombstone and archive another device's
live agents at boot. Agent deletion-retry therefore stays a pre-existing
gap owned by the direct delete path (tracked in Follow-ups).

**Inbound relay-contract alignment (`retention.rs`,
`commands/personas/inbound.rs`).** Two inbound rules now match the
relay:
- *Equal-second tie-break.* `inbound_event_outcome` previously treated
every equal timestamp as stale; the relay resolves equal `created_at` by
lowest event id. Preflight now matches the relay tuple — strictly newer
timestamp wins, equal timestamp resolves by lower event id, an exact
echo skips — so two devices authoring different same-second successors
converge instead of one silently republishing an event the relay
refuses.
- *Covered-head resolution on inbound kind:5.*
`reconcile_inbound_tombstone` previously consulted only the retained
kind:5 row, so a historical tombstone replayed after a newer recreation
deleted the recreated record and never purged the covered head.
Preflight now resolves both the tombstone row and the covered
`(target_kind, owner, d_tag)` head: a target head strictly newer than
the tombstone preserves JSON and skips; an actually-covered head is
removed from disk first (fallible), then the tombstone row commit and
covered-head purge happen atomically. A JSON-save failure advances
neither, so the identical event stays retryable.

**Atomic agent-archive coupling (`commands/agents_pending.rs`).** The
30177 tombstone and the 9035 archive request now enqueue in one `BEGIN
IMMEDIATE` transaction, with the archive's `persona_id` derived from the
retained head (`persona_id_from_head`) rather than the deleted record,
where it survives the tombstone as owner-signed historical alias data.
The standalone `archive_managed_agent_pending` production callers are
removed — there is no double-enqueue path. Unlike personas/teams, this
coupling is not re-enqueued by the boot deletion reconcile (30177 is
excluded, above): a crash after the disk-authoritative record is removed
but before this transaction commits leaves agent deletion-retry a
pre-existing gap owned by this direct delete path (tracked in
Follow-ups).

## Follow-ups

`publish_prepared_persona` (`commands/personas/sharing.rs`) has the
identical direct-submit-outside-the-lock race for 30175 persona heads
that this PR fixes for 30178 team heads. It predates this work and is
tracked in the separate persona-tombstone follow-up PR, not folded here.

The app-wide `http_client` leaves reqwest's connect/read/total timeouts
unset (`app_state.rs` builder configures only pool options). This PR
bounds the team-publish call site with a `tokio::time::timeout`, but
every other consumer of the shared client remains exposed to a
non-responding endpoint. A client-wide default timeout is the broader
fix; it is pre-existing on main and affects all consumers, so it is out
of scope here.

Managed-agent deletion-retry: the atomic 30177 tombstone + 9035 archive
is best-effort, and unlike personas/teams it is deliberately excluded
from the boot deletion reconcile (a device-local-absent 30177 head is
the normal cross-device state, not a deletion). A crash between the
delete's store write and its retention enqueue therefore has no boot
backstop for agents. The durable fix is a local deletion intent written
before the record is removed; deferred rather than folded into this
round.

ae0ecd9a67 feat(model-capabilities): humanize Databricks UC model families (#6955)
Chat-eligible Unity Catalog models from the Gemini, DeepSeek, GLM, Grok,
Llama, Qwen, Gemma, and Inkling families were rendering as raw FQNs such
as `system.ai.gemini-3-5-flash` in the agent model picker. #6918
surfaces these models, but the capability manifest carried no records
for most of them and the registry-label path could not strip their Unity
Catalog or `goose-` prefixes.

I added a display-only `label_family_tokens` list and `databricks_v2`
exact records for the sixteen previously unlabeled endpoint stems. All
26 target FQNs and their `goose-` aliases now resolve to curated labels
through `databricks_registry_label`, while capability resolution
continues to use only the existing `family_tokens` (`claude-`, `gpt-`,
and `kimi-`). This keeps label discovery from changing capability
profiles for unrelated model IDs.

Each new record includes reconciliation metadata against the pinned
[models.dev catalog](https://models.dev/api.json). Nine records adopt
first-party effort evidence that the Databricks MLflow Chat transport
can express: Gemini 3.5 Flash, Gemini 3.5 Flash Lite, Gemini 3.6 Flash,
Gemini 3 Pro Image, DeepSeek V4 Flash, DeepSeek V4 Pro, GLM-5.3 Flash,
Grok 4.6, and Inkling. The remaining seven deliberately retain the
`databricks_v2/concrete_unknown` fallback because upstream evidence is
absent, identifies a non-reasoning model, or provides only
toggle/token-budget controls that `reasoning_effort` cannot represent.

The normative corpus adds the sixteen exact records, four Unity Catalog
alias probes, and two capability-isolation probes. Existing base vectors
remain unchanged, and Rust and TypeScript consume the same strict
manifest and corpus.

be8d7756d5 feat(agent): discover Databricks Unity Catalog models (#6918)
## Summary

Add Unity Catalog model-service discovery to `buzz-agent` Databricks v2,
preserve full Unity Catalog FQNs through ACP model discovery, route
model services through MLflow chat, and add the optional
`DATABRICKS_MODEL_FILTER` visibility filter.

The resilience follow-up bounds each catalog attempt across headers,
bounded body reads, and JSON parsing; retries transient 499/5xx,
transport/body failures, malformed JSON, and attempt timeouts; and emits
only safe catalog/status diagnostics.


## Validation

The live validation and test gates below were run on the pre-rewrite tip
`1cf6c66e7c5bf9a00c357bda24df48e3beeb310b`. The rewritten tip
`0364cf44f3eb5cfbd5771b0a0dd7868ce0ad2c19` has identical trees for both
commits, so the attribution rewrite changes no tested code.

- 31 catalog tests passed
- 19 Databricks OAuth/routing integration tests passed
- `cargo check -p buzz-agent` passed
- `cargo clippy -p buzz-agent --all-targets -- -D warnings` passed
- `cargo fmt --check` passed
- `git diff --check` passed
- Desktop Tauri validation passed through the repository-supported setup
path, including 2,777 library tests and auxiliary terminal suites

The full `buzz-agent` package has one separately reproduced pre-existing
failure: `regressions::cancel_kills_inflight_tool_via_mcp_notification`,
failing on both baseline `eb8e97cfe` and the follow-up worktree. No
Databricks path reaches that test. The live validation proves discovery
and ACP exposure, not inference against every listed model.

69096c9a8d preserve channel description paragraph breaks (#6946)
**Category:** fix
**User Impact:** Channel descriptions now keep their paragraph structure
everywhere people and agents read them.

**Problem:** Multi-paragraph channel descriptions were flattened in the
desktop interface and in agent context, making operational instructions
harder to scan and potentially changing their meaning. A running agent
harness could also continue using a stale description after someone
edited it.

**Solution:** Preserve authored line and paragraph breaks across the
desktop surfaces, and render descriptions as bounded, indented
agent-context blocks with semantic delimiters escaped. Prompt-visible
channel metadata now refreshes before each turn with cached fallback,
while one shared desktop derivation keeps the header and channel intro
consistent.

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

**crates/buzz-acp/src/pool.rs**
Refresh prompt-visible kind-39000 metadata with one bounded request per
turn so edits reach running harnesses, while retaining cached metadata
as a degradation fallback. Add regression coverage for description edits
and update request-count fixtures for the refresh lifecycle.

**crates/buzz-acp/src/prompt_framing.rs**
Add semantic text escaping for untrusted values embedded inside paired
prompt sections.

**crates/buzz-acp/src/queue.rs**
Render multi-paragraph descriptions as indented context blocks, preserve
blank lines, retain the 500-character limit, and escape semantic
delimiters. Add helper- and full-prompt tests for paragraph
preservation, UTF-8-safe truncation, and adversarial input.

**desktop/src/features/channels/lib/channelDescription.ts**
Introduce one shared channel-detail derivation and preserve newlines
between status context and authored detail text.

**desktop/src/features/channels/lib/channelDescription.test.mjs**
Cover shared field precedence, multiline descriptions, status-prefix
separation, and fallback behavior.

**desktop/src/features/channels/ui/ChannelPane.helpers.ts**
Use the shared channel-detail derivation for the channel intro instead
of maintaining a second field order.

**desktop/src/features/channels/ui/ChannelPane.helpers.test.mjs**
Verify description text wins consistently over legacy purpose text when
both are present.

**desktop/src/features/channels/ui/ChannelManagementSheetRows.tsx**
Preserve paragraph whitespace in editable and read-only channel
summaries and allow enough lines for compact multi-paragraph
descriptions.

**desktop/src/features/channels/ui/ChannelManagementSheetRows.test.mjs**
Render both channel-summary variants and assert the multiline whitespace
and four-line clamp contract.

**desktop/src/features/messages/ui/ChannelIntroBlock.tsx**
Display description line and paragraph breaks in the empty-channel
intro.

**desktop/src/features/messages/ui/ChannelIntroBlock.test.mjs**
Add render-level coverage for the intro's multiline whitespace contract.

</details>

## Reproduction steps

1. Run the desktop app and create an empty channel.
2. Give it a description with two paragraphs, including a blank line and
a multi-line second paragraph, then save and reopen channel management.
3. Confirm the empty-channel intro preserves the blank line and
subsequent line breaks.
4. Confirm the channel-management summary shows the paragraph structure
for both an editor and a read-only member rather than a detached
ellipsis.
5. Hover the channel title and confirm its tooltip keeps the
description's line breaks.
6. Add an agent, send one prompt, edit the description, then send
another prompt. Confirm the next generated agent context contains the
updated description as an indented multiline block.

channel-management summary is attached in the PR comments below.

Closes AIDA-1980.

4d77175c78 fix(client): resurface hidden DMs from live activity (#6885)
## Summary

Hiding a DM row and then receiving a new message from that person never
brought the row back — the reader was left with only an Inbox
notification. This restores the row from live activity, client-side,
with no relay or database changes.

- Subscribe to hidden-DM activity **channel-scoped** over the hidden-DM
id set (`#h`), re-registering whenever the set changes. The relay's
`fan_out_scoped` only routes channel-scoped events (every kind:9 DM
carries a `channel_id`) to channel-scoped subscriptions, so a
community-global `#p` filter receives nothing. Hiding a DM never drops
membership, so `#h` authorization holds. Because every delivered event
is already for a hidden DM the reader belongs to, eligibility no longer
needs a self `p` tag — untagged CLI/agent DMs resurface too — and no
per-event visibility fetch is required.
- On qualifying activity, invoke the existing open-DM action (`41010`)
to reopen the hidden one-to-one or group DM, validating that the relay
reopened the same channel.
- Preserve the existing relay-synced hide snapshot (`41012` → `30622`);
hide state still syncs across devices.
- Let Inbox reopen a hidden DM before navigating to its message, with a
busy state on the row and context-menu "Open in channel" action while a
reopen is pending.
- Coalesce resurface attempts per channel: a concurrent message that
arrives while a reopen is in flight triggers a retry on failure instead
of being marked handled and dropped.
- Write exact dm-visibility query keys on open/hide mutations.

This is the client-only replacement agreed in the Buzz design thread and
supersedes #6713. The accepted limitation is that resurface only fires
while a client is running — a message that arrives while all clients are
closed does not restore the row on next launch (the `30622` snapshot has
no watermark); Inbox click-through is the safety net for that case.

Addresses #6316.

c856be0fb9 fix(desktop): keep the draft space when typing right after a mention pick (#6875)
## Problem

Desktop Smoke E2E flaked on `mentions.spec.ts` ("typing a mention before
existing text does not interleave spaces"): picking a suggestion
mid-draft and typing immediately could swallow the draft's own space,
producing `hello @bob abcworld` instead of `hello @bob a world`.

With `hello world` drafted and ` @bo` typed after `hello`, picking the
suggestion leaves `hello @bob world` — the mention's trailing space
followed by the draft's space. Chromium reconciles that whitespace run
by re-emitting it as a replacement (`replace(" " -> " a")`), anchored at
*either* edge of the run. The settling-time text-input redirect only
recognized a caret or a rewrite anchored at the chip edge, so the other
shapes fell through to ProseMirror's destructive default and ate the
separator.

The race pre-dates this branch and reproduces on `main`.

## Fix

`mentionHighlightExtension.ts` now redirects on the invariant instead of
on a specific rewrite shape. While autocomplete is settling the user
cannot have a selection (a selection cancels settlement), so a
whitespace-only replacement adjacent to a mention's trailing space is
always the browser normalizing whitespace — never an intentional delete.
The handler keeps every space already in the document and inserts only
the typed characters after the token, whichever edge the rewrite is
anchored at. Non-whitespace replacements still fall through as real
edits.

`insertPosForMentionTextInput` / `mentionTextInputInsertPos` become
`insertionForMentionTextInput` / `mentionTextInputInsertion`, returning
`{insertAt, text}` so the handler can rewrite the payload, not just the
position.

## Tests

- Helper-level cases for all four anchors (caret at chip edge, caret
past the trailing space, run rewritten from the chip edge, draft space
rewritten alone), plus space/NBSP variants and a non-whitespace
replacement that must be left alone.
- A plugin-level test drives the real `handleTextInput` prop and falls
back to ProseMirror's default when it declines — exactly as the browser
does with the return value — so it fails against the previous production
code rather than depending on winning a timing race in a headless
browser.

Desktop unit suite passes on pre-push (5558/5558).

cada3028ce fix(desktop): keep project sheets independent from threads (#6901)
## Summary

Project workspace sheets now slide in from the right as an independent
layer over an open conversation thread instead of replacing the thread
or rendering inside its panel. Closing the sheet restores the unchanged
thread, Escape applies only to the topmost surface, and the covered
thread's resize divider no longer leaks through the overlay.

### Related issue

Related: #6602. No matching issue found.

### Testing

- `pnpm --dir desktop exec biome check

ceb8ba605f fix(desktop): accent-colored mention badges that count thread mentions (#6900)
**Category:** fix
**User Impact:** Sidebar mention numerals now match the user's
theme/accent color and appear for mentions inside threads, not just
top-level channel messages. Hover-to-preview on channel rows is
unchanged.

**Problem:** Follow-ups to #6696:

1. The mention numeral used a fixed red `--notification` token that
ignored the user's theme and accent selection.
2. The numeral read `appBadgeCount`, which deliberately excludes
threaded replies (Home's badge subtotal counts those toward the Dock
badge). Mentions inside threads therefore never surfaced a numeral on
the channel row — only the generic thread-activity dot.

**Solution:**

1. The badge now reuses the primary accent pair (`bg-primary` /
`text-primary-foreground`), the same treatment as the DM count badge, so
it follows whatever accent the user applies — including the pinned
neutral accent of the Buzz themes. The now-unused `--notification`
tokens and Tailwind utilities are removed.
2. Non-DM rows now count every unread mention/broadcast — threaded or
top-level — via a new `highPriorityCount` channel projection, replacing
the boolean `highPriorityUnread` across the TS contract, the Tauri
SQLite store, the e2e mock bridge, and the native test rig. The Dock/app
badge projection (`appBadgeCount`) is unchanged, so Dock totals do not
double-count thread activity that Home already counts.

The hover-to-preview channel activity popover is untouched; e2e coverage
now pins the combination (thread mention → numeral, no dot, popover
still opens and lists the mentioning reply).

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

**desktop/src/features/channels/useUnreadChannels.ts**
Non-DM sidebar counts switch from `appBadgeCount` to the
mention/broadcast-inclusive `highPriorityCount`; the high-priority
channel set derives from the same count.

**desktop/src/features/sidebar/ui/SidebarSection.tsx**
Badge drops the fixed notification classes and inherits the
accent-following default.

**desktop/src/shared/styles/globals/theme.css /
desktop/tailwind.config.js**
Remove the unused fixed `--notification` tokens and semantic utilities.

**desktop/src/shared/api/tauriObservedUnread.ts /
desktop/src-tauri/src/observed_unread.rs**
Projection contract: `highPriorityUnread: bool` → `highPriorityCount:
u64`, aggregated per unread high-priority event.

**desktop/src/testing/e2eBridge.ts /
desktop/src/features/channels/observedUnreadNativeRig.mjs**
Mock/native-rig projections mirror the new count field.

**desktop/src/features/channels/observedUnreadNative.test.mjs**
Native badge-lane test seeds a high-priority event to match the
numeral's new semantics.

**desktop/tests/e2e/badge.spec.ts**
Top-level mention test now asserts the badge equals the applied accent
(seeded `#22c55e` under an adversarial theme). New test: in-thread
mention shows the numeral, no dot, and the hover preview popover still
lists the mentioning reply.

**desktop/tests/e2e/channel-activity-popover.spec.ts /
desktop/tests/e2e/thread-unread.spec.ts**
Seeded fixtures that mention the user now expect the numeral (which
subsumes the dot).

</details>

## Reproduction steps

1. Pick any theme + accent color in Settings → Appearance.
2. Receive a top-level message mentioning you in an inactive channel →
the row shows a numeral pill in your accent color.
3. Receive a reply **inside a thread** that mentions you in an inactive
channel → the row shows the numeral (previously only a dot).
4. Hover the row → the channel activity preview still opens and lists
the mentioning reply.
5. Switch accents/themes → the pill re-colors accordingly; the Dock
badge count is unchanged from before.

## Verification

- `tsc --noEmit`, Biome, `check:px-text` — clean
- Desktop unit tests: 179/179 channel-suite; full suite has one
pre-existing failure from #6590 (`useRetainedProjectGitViews.test.mjs`
loader error, fails on clean `main`)
- Tauri Rust: `observed_unread` tests + clippy + fmt — clean
- Playwright smoke: badge (19), channel-activity-popover (10),
thread-unread (13), plus channels/inbox/stream/messaging/mentions suites
— all green

eb8e97cfe7 fix(desktop): show edited head content in thread panel (#6887)
## Why

Fixes #6886. In the channel timeline an edited message shows its newest
body, but opening its thread panel showed the stale pre-edit body until
the async thread-aux backfill landed (and permanently if it raced or
missed).

## Root cause

`desktop/src/features/messages/lib/independentThreadPanel.ts` built
`events = [head, ...replyEvents]`, discarding the head's aux overlay
events (edits `kind:40003`, deletions, reactions) already present in the
channel window. `formatTimelineMessages` only applies an edit when the
edit event sits in the same array as its target, so the thread head
relied solely on `withThreadAux` to re-supply it.

## What

- Carry the head's non-content aux events (via
`!isTimelineContentEvent`) from the channel window into the thread
head's event array, deduped against `replyEvents` by id.
- Thread head is now byte-identical to the main timeline the instant the
thread opens, independent of the async aux fetch.
- Restricted to non-content kinds so reply content rows never leak in.

## Tests

- Unit regression `independentThreadPanel.test.mjs` (6 cases): red
pre-fix (`"two PRs"`), green post-fix (`"these PRs"`).
- e2e `thread-head-stale-edit.spec.ts`: delays thread-replies aux to
force the channel-window-vs-thread-aux divergence, then opens the thread
via the reply button and asserts the panel head shows the edited body.
Verified red pre-fix (stale `message-thread-panel` head), green
post-fix.
- Full desktop unit suite: **5562 pass / 0 fail**. `biome` + `tsc
--noEmit` clean.

Origin: Buzz channel `fix-reply-thread-old-view-bug`
(#464b982f-fc05-42c8-918f-409e1f05a1df).

03bfc837cb fix(desktop-tooltip): increase surface contrast (#6897)
**Category:** fix
**User Impact:** Tooltips now use a higher-contrast surface, making
their labels easier to read across desktop themes.

**Problem:** Tooltip surfaces could blend into hovered content, making
labels difficult to distinguish.

**Solution:** Use the existing popover surface and foreground tokens for
clearer visual separation and theme-aware contrast.

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

**desktop/src/shared/ui/tooltip.tsx**

1. Run the desktop app and hover a control that displays a tooltip.
2. Compare the tooltip against the content beneath it in both light and
dark themes.
3. Confirm the tooltip surface remains clearly distinguishable and its
label is readable.

01c87a350b Apply access policy when reusing channel agents (#6838)
Reused managed identities now apply their intended inbound-author policy
before attachment or startup. An explicit policy wins, then the linked
persona policy, then `owner-only`.

This covers both channel-agent provisioning and the direct composer
autocomplete path. If the policy update fails, attachment, startup, and
message send stop.

The production Playwright regression starts with a persona-linked agent
set to `anyone` with a stale allowlist, then verifies the update happens
before membership and startup and that the stored policy is
`owner-only`. A small resolver test covers explicit, persona, and
default precedence.

This closes the stale-policy entry described by [Project Loupe issue
#497](https://github.com/project-loupe/audit-buzz/issues/497). The
separate Welcome Team reuse path is outside this PR.

Checked with the 5,502-test desktop suite, `pnpm check`, `pnpm
typecheck`, `pnpm check:file-sizes`, and the focused Playwright composer
regression.

4f554b6385 feat(sidebar): prioritize unread DMs in overflow navigation (#6842)
**Category:** improvement
**User Impact:** Users can see which unread direct messages are waiting
offscreen and jump to the most relevant one first.

**Problem:** The sidebar overflow control treated every offscreen unread
conversation alike, so an unread DM could be hidden behind channel
activity with no visible clue about who was waiting.

**Solution:** Prioritize the first offscreen unread DM, preview up to
three senders with avatars, and keep the arrow, avatars, separator, and
message count intact while only the trailing phrase truncates in narrow
sidebars.

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

**desktop/src/features/sidebar/lib/useUnreadOverflow.ts**
Adds ordered DM preview data to unread-overflow calculations while
preserving the sidebar's existing visibility and direction rules.

**desktop/src/features/sidebar/lib/useUnreadOverflow.test.mjs**
Covers DM prioritization, ordering, offscreen filtering, and
channel-only fallback behavior.

**desktop/src/features/sidebar/ui/AppSidebar.tsx**
Passes unread DM previews into the lower overflow control and navigates
to the preferred DM before the next unread channel.

**desktop/src/features/sidebar/ui/MoreUnreadButton.tsx**
Renders the frontmost-first avatar stack, accessible DM target label,
middot separator, and message-count treatment.

**desktop/src/features/sidebar/ui/MoreUnreadButton.test.mjs**
Locks the three-avatar cap, stacking order, preferred target, fallback,
accessible copy, and truncation structure.

**desktop/src/shared/ui/UnreadPill.tsx**
Contains the primary pill and allows only its trailing label to
ellipsize under width pressure.

**desktop/src/shared/ui/UserAvatar.tsx**
Allows the sidebar preview stack to identify each rendered avatar in
regression coverage.

</details>

## Reproduction steps

1. Open enough sidebar conversations that unread items fall below the
visible area.
2. Leave one or more offscreen DMs unread, along with unread channels.
3. Confirm the bottom overflow pill shows up to three overlapping DM
avatars followed by a middot and the total new-message count.
4. Select the pill and confirm it navigates to the first offscreen
unread DM rather than the nearest unread channel.
5. Resize the sidebar from 420px through 300px to 220px and confirm the
arrow, avatars, middot, and full numeric count remain visible; only `new
messages` may ellipsize.
6. Repeat with channel-only unread overflow and confirm the control
keeps its channel fallback behavior without avatars.

de188ebf06 feat(projects): add agent and CLI project-home support (#6590)
## Summary
- inject bounded project-home identity and repository context into
managed agent sessions
- add project-aware CLI flows for creating projects, repositories,
issues, and related channels
- match project homes through the existing relay query surface, then
filter channel metadata client-side

This is Part 1 of the channel-first Projects stack. Part 2 contains
project creation and model foundations.

## Testing
- `cargo fmt --all -- --check`
- `cargo clippy -p buzz-cli -p buzz-acp --all-targets -- -D warnings`
- `cargo test -p buzz-cli -p buzz-acp` — 1,184 tests passed, 1 doc test
ignored
- full pre-push gate passed

## Post-Deploy Monitoring & Validation
- validate project-home agent context and project-aware CLI commands
against a staging relay
- healthy signals: project context matches the active channel, explicit
repo coordinates remain stable, and normal channels receive no project
block
- failure signals: cross-channel project context, duplicate project
creation, or commands targeting an unrelated repository; mitigate by
reverting this PR

f177f4909d Use paired tags for standing & per-turn context (#6701)
## Why
PR #6503 bundled a broader context compiler with several prompt-shape
and telemetry changes, making it difficult to isolate whether paired
XML-like top-level boundaries improve agent behavior. This keeps the
follow-up experiment focused on framing only.

## What
- Replace top-level standing and per-turn bracket headers with paired
tags while preserving inner section content and event/message framing
- Carry only metadata already present in dynamic headers as attributes,
such as thread counts, truncation, event type, and batch count
- Preserve every section body verbatim so the model executes the exact
bytes reviewed in Desktop
- Keep routing metadata, event content, batching, and delivery behavior
unchanged
- Teach Desktop diagnostics to parse the new framing while retaining
compatibility with archived bracket-framed sessions; ambiguous paired
boundaries render as the complete captured prompt

## Risk Assessment
Medium — the change is limited to agent prompt framing and diagnostic
parsing, but it affects both standing context and every dynamic agent
turn. Bodies and delivery behavior remain unchanged, and compatibility
parsing remains for prior sessions.

## References
- Follow-up to #6503, scoped only to the paired-tag framing hypothesis

## Update — 2026-08-24
- Addressed review feedback by removing entity encoding/decoding from
the execution and diagnostic paths.
- Added regressions for literal closing tags, placeholders,
entity-looking text, ampersands, and authored boundary whitespace.
- Verified `cargo test -p buzz-acp` (805 unit + 9 integration), Desktop
tests (5,412 before the main sync; 5,439 in the pre-push gate), Desktop
typechecking, and Tauri clippy/tests.
- Live local relay startup and message ingestion passed. The live ACP
reply step is blocked locally because installed Goose 1.0.23 no longer
provides the documented `goose acp` command and no alternate ACP adapter
is installed.

---

**Update Aug 25, 12:13 EDT:** Extended paired tags to per-turn top-level
sections.

- Converted context, conversation/thread context, event batches, and
steer/interrupt boundaries without changing their inner bodies.
- Preserved existing header metadata as attributes only; added no new
prompt metadata.
- Verified 806 Buzz ACP unit tests plus 9 integration tests, 5,441
Desktop tests, Desktop typechecking and formatting, and all differential
pre-push lanes.

---

**Update Aug 25, 13:58 EDT:** Addressed framing review feedback.

- Updated operational base instructions to reference the emitted
`<context>` section and added a regression guard against stale
`[Context]` instructions.
- Restored batched steer/interrupt cardinality in Desktop diagnostic
titles with focused coverage for both paths.
- Verified 807 Buzz ACP unit tests plus 9 integration tests, 5,442
Desktop tests, Desktop typechecking and formatting, and every
differential pre-push lane including Tauri clippy/tests.

---

**Update Aug 25, 15:37 EDT:** Hardened legacy transcript compatibility.

- Semantic standing-context parsing now requires paired framing at the
start and complete input consumption.
- Historical bracket-framed personas keep literal balanced tag examples
in their original section; malformed or mixed current framing displays
as the complete captured prompt.
- Added regressions for the reported legacy persona case and trailing
unframed text; verified 60 focused parser tests, 5,444 full Desktop
tests, formatting, and typechecking.

---

**Update Aug 25, 16:31 EDT:** Preserved slash-command prompt block
boundaries.

- Desktop now sets aside a valid connector-facing slash-command block
only when the following block begins recognized paired framing, parses
the semantic blocks normally, and retains the command as visible Prompt
metadata.
- Added an end-to-end transcript regression using the production
three-block ACP shape, including the user bubble, author pubkey, event
ID, and grouped prompt context.
- Verified 113 combined transcript tests, 5,445 full Desktop tests,
formatting, typechecking, and all applicable pre-push lanes.
