What users saw

Desktop-managed Buzz agents could receive only the built-in buzz-dev-mcp server. Operators had no process-level way to attach additional MCP servers to the ACP session.

What changed

  • Adds BUZZ_ACP_EXTRA_MCP_COMMANDS for comma-separated extra MCP server commands.
  • Parses each command with shell-aware quoting and preserves quoted paths and empty arguments.
  • Fails startup before connecting to the relay when quoting is malformed, without echoing the command in the error.
  • Generates deterministic, unique MCP server names that satisfy the agent name validator.
  • Keeps Buzz relay credentials out of extra MCP server environments.
  • Reserves the setting from portable persona and per-agent environment overrides because it is a code-execution surface.
  • Documents configuration, quoting, security boundaries, and an example in the ACP README and .env.example.

Example:

BUZZ_ACP_EXTRA_MCP_COMMANDS='npx -y first-mcp,"/opt/MCP Servers/second" --stdio'

Verification

  • just ci
  • cargo test -p buzz-acp --quiet (786 unit tests and 9 lifecycle tests)
  • cargo clippy -p buzz-acp --all-targets -- -D warnings
  • Focused Desktop reserved-environment-key test

Non-goals

  • No dedicated Desktop configuration UI.
  • No config-file format.
  • No Buzz credential forwarding to extra MCP servers.

Closes #6023

## Overview

**Category:** improvement  
**User impact:** Link previews appear in the composer and travel as
privacy-safe sender-authored snapshots, so recipients never contact the
linked site merely by opening a conversation.
**Problem:** Cold-cache link paste could freeze the composer before the
URL painted; recipient-side unfurling leaked visits; invalid or
unresolved preview work could interfere with sending or leave dead cards
behind.
**Solution:** Paint pasted links before starting cold resolver work,
resolve only in the sender's composer, attach only complete validated
snapshots at Send, and render authored snapshots without recipient
fallback fetching.

## Behavior

- **Cold paste stays responsive:** bare and angle-bracket URL paste
paths commit the visible link before resolver work begins.
- **Sender-only fetching:** metadata is resolved while composing;
recipients render only the sender-authored snapshot.
- **Send never waits:** pending, failed, invalid, and unsendable
previews are omitted. They do not block or cancel the message.
- **Terminal misses disappear:** failed, timed-out, or 404 resolver
results remove the composer card while preserving visible link text.
- **Display-text links work:** Markdown links such as `[review the pull
request](…)` produce and send the same snapshots as bare URLs.
- **Compact and Rich presentation:** Compact remains the default; Rich
preserves source description line breaks and paragraphs.
- **Immediate draft-wide dismissal:** clicking × immediately hides all
previews for the draft, suppresses links pasted later, and emits only
`["link-preview", "none"]`. No confirmation detour. Suppression resets
after send or clearing the draft.
- **Zero recipient fallback:** missing, stale, malformed, off-relay,
unsupported, or suppressed snapshots remain ordinary visible links;
recipients never regenerate them.

## Implementation

- Resolve previews from deferred composer URL state so paste can paint
first.
- Upload finished preview media to the active community relay and
snapshot only valid, sendable media references.
- Atomically capture ready snapshots at submit time; never append a late
preview after send.
- Validate snapshot and suppression tags in desktop/native and relay
ingestion, rejecting duplicate or mixed forms.
- Render composer previews as stable 55px attachment cards at desktop
and narrow widths.
- Add deterministic E2E coverage for cold paste,
ready/pending/failed/invalid previews, display-text links, multiline
Rich descriptions, immediate dismissal, later-pasted links, and
suppression reset.

## Validation

Validated head: `64f2e2937a2c70e388c132ae14b6be6d11716db8`

- Push hooks passed: `check-push-org`, branch skew, desktop check,
mobile tests, desktop tests, Rust tests, and desktop Tauri checks.
- Focused screenshot E2E at the validated head: 5/5 passed across
Compact/Rich composer and recipient states, 800px/420px geometry,
display-text links, multiline descriptions, and immediate dismissal.
- PR CI was triggered for this exact head and is currently running;
completed checks are green at the time of this update.
- Worktree is clean and both PR head and validated branch resolve to
`64f2e2937…`.

…lders (block#4975)

## What users saw

`buzz messages send` silently removed an explicitly supplied
self-mention. The caller passed `--mention <sender-pubkey>` and received
`accepted:true`, but the signed event had no matching `p` tag and
`mention_pubkeys` was empty.

## Why it happened

`nostr` 0.44 strips `p` tags matching the signer's pubkey by default.
The codebase already opts out with `.allow_self_tagging()` for identity
archive and unarchive requests, but the message and forum builders that
accept mentions did not. The library therefore removed the tag during
signing after the CLI had validated the explicit mention.

## What changed

Added `.allow_self_tagging()` to all three event builders that accept
mention tags:

- `build_message` (kind 9)
- `build_forum_post` (kind 45001)
- `build_forum_comment` (kind 45003)

An explicit mention now survives signing even when it matches the
sender.

## How this was tested

Added one regression test per builder. Each test signs with the same key
included in the mention list and asserts that the resulting event
preserves the self-referential `p` tag.

Validation at `1ea172355`:

```text
./bin/cargo fmt --all -- --check
cargo test -p buzz-sdk --lib
cargo test -p buzz-cli --lib
cargo clippy -p buzz-sdk -p buzz-cli --all-targets -- -D warnings
```

All 257 `buzz-sdk` tests and all 321 `buzz-cli` tests passed, and
formatting and strict Clippy checks completed successfully.

## Scope and non-goals

- Does not change mention validation, deduplication, or channel-member
checks.
- Does not change `normalize_mention_pubkeys`, which is not used by the
messages-send path.
- Does not add a dropped-mentions output field because the explicit tags
are now preserved.

Closes block#4906.

**Category:** fix
**User Impact:** Mobile users who jump to Latest now see the newest
message fully above the composer instead of partially hidden behind it.

**Problem:** The channel message list treated the raw viewport bottom as
the latest boundary even though the composer occupies part of that
viewport. Latest jumps and follow-mode corrections could therefore place
the newest message underneath the composer.

**Solution:** Derive the latest alignment from the measured composer
inset and use that same boundary for scrolling, follow detection, and
layout correction.

<summary>File changes</summary>

**mobile/lib/features/channels/channel_detail_page/message_list.dart**
Aligns Latest navigation and follow-mode correction with the visible
bottom edge above the composer, and evaluates boundary state against the
same geometry.

**mobile/test/features/channels/channel_detail_page_test.dart**
Adds a regression assertion that the newest live message clears the
composer and that the Latest control disappears after navigation.

</details>

## Reproduction steps

1. Open a mobile channel with enough messages to scroll away from the
newest message.
2. Tap **Latest**.
3. Confirm the newest message is fully visible immediately above the
composer and the **Latest** control disappears.
4. Resize the composer or keyboard while following latest and confirm
the newest message remains above the composer.

## Tested fix

The newest message remains fully visible above the composer after
jumping to **Latest**.

## Buzz Desktop release v0.5.6

- **Frozen main:** `c814c9ef463408dba61346b6de5d4b4cd5f5490d`
- **Reviewed candidate:** `62158ac1b581f38ba64e80868f6c88e9e1ecf554`
- **Previous desktop release:** `desktop-v0.5.5`
- **Proposed immutable tag:** `desktop-v0.5.6`

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

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

## Summary

- treat provider `max_tokens` as an interrupted assistant response and
continue the same turn with actionable feedback
- discard tool calls from truncated responses, including malformed
partial arguments, so they are neither executed nor replayed with
invalid tool-result pairing
- bound recovery to two retries while preserving normal finite
`max_rounds` accounting

## Verification

- `cargo fmt --all -- --check`
- `cargo test -p buzz-agent` (422 unit tests plus all package
integration/doc suites passed)
- `cargo clippy -p buzz-agent --all-targets -- -D warnings`

## Notes

The pre-push repository-wide hook also ran. Its Rust tests passed (2,270
passed, 14 ignored), but its `buzz-db` unit-test build was blocked
because local rustc 1.89 is below sqlx 0.9's rustc 1.94 requirement. The
affected package suite above is green on the exact pushed commit.

…block#5228)

**Category:** fix
**User Impact:** People who onboard by importing an existing key or
recovering from a phone can now use "Skip for now" (and Next) on the
harness setup and model config steps, instead of getting stuck.

**Problem:** On the "Set up your agent harnesses" and "Configure your
default model settings" onboarding steps, clicking **Skip for now** — or
**Next** — did nothing for anyone who reached those steps by importing
an existing key or recovering an identity from a phone. The app stayed
frozen on the step.

**Solution:** The onboarding state machine sets `continuingPubkeyRef` to
the current pubkey on import/recovery to keep the flow on `onboarding`
until setup finishes (added in block#4845). But `complete()` never cleared
that ref, so once it matched the current pubkey the stage stayed pinned
to `onboarding` forever — completion could never win. `complete()` now
clears the ref so finishing/skipping actually settles the flow.
Fresh-generated keys never set the ref, which is why first-run fresh-key
skip already worked and the gap went unnoticed.

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

**desktop/src/features/onboarding/machineOnboarding.ts**
Clear `continuingPubkeyRef` inside `complete()` so an imported/recovered
identity's "continuing" marker no longer outlives completion and pin the
stage to `onboarding`.

**desktop/tests/e2e/onboarding.spec.ts**
Add a regression test that imports an existing key, reaches harness
setup, clicks **Skip for now**, and asserts onboarding exits (reaches
community onboarding). This fails without the fix. The existing skip
tests only exercised the fresh-key path, which never set the ref — hence
the gap.

</details>

## Reproduction steps

1. Start onboarding and choose **Use an existing key** (or recover from
a phone); import a key and continue to **Set up your agent harnesses**.
2. Click **Skip for now** (or **Next**). Before this change, nothing
happens — the step is stuck. The same trap hits **Configure your default
model settings**.
3. With this change, Skip/Next advances out of onboarding as intended.
4. Automated: `pnpm build:e2e && pnpm exec playwright test
onboarding.spec.ts --project=integration -g "imported-key users can skip
out of harness setup"` — passes with the fix, fails without it.

## Root cause

Introduced by block#4845 (`feat(identity): recover desktop identity from a
signed-in phone`), which added `continuingPubkeyRef.current ===
currentPubkey` as an independent condition selecting the `onboarding`
stage. That guard has no off switch: `complete()` set the completion
flag but never cleared the ref, so the OR'd condition kept the stage
pinned. Not a revert candidate — the guard's intent (keep a
just-published identity in onboarding until setup finishes) is correct;
it just needed to release on completion.

…rride (block#5242)

## Problem

Two v0.5.6-only regressions were introduced by block#4614 (the first enforced
Tauri CSP):

1. **Tab-complete caret regression** — after tab-completing an @mention,
#channel, or :emoji: shortcode, the cursor landed inside the inserted
text instead of after the trailing space. TipTap inserts the correct
text including the trailing space, but without its base stylesheet
(`.ProseMirror { white-space: break-spaces }`) the trailing space
collapses visually and the caret appears mid-name.

2. **Emoji picker unstyled** — the emoji-mart picker rendered as a giant
unstyled layout (oversized search SVG, collapsed grid) because
emoji-mart's shadow-root stylesheet injection was also blocked.

Both symptoms have the same root cause.

## Root Cause

Tauri's build-time asset processor scans `index.html` for inline
`<style>` elements, injects a nonce token, and adds the corresponding
`'nonce-…'` source to `style-src` at runtime. Per the CSP spec, **once a
nonce is present in a directive, the browser ignores `'unsafe-inline'`
for that directive**.

`index.html` contained an inline `<style>` with the boot background
color. When Tauri nonced it and injected `'nonce-…'` into `style-src`,
the intended `style-src 'self' 'unsafe-inline'` became effectively
`style-src 'self' 'nonce-…'` — blocking any runtime stylesheet injection
not covered by a matching nonce:

- TipTap's `injectCSS()` → `createStyleTag()` injecting `.ProseMirror {
white-space: break-spaces; … }`
- emoji-mart's shadow-root `document.createElement('style')` injection

(Inline scripts follow a separate path — they are SHA-256 hashed, not
nonced.)

This only reproduces in packaged builds (where Tauri's custom protocol
serves the HTML and enforces the policy). `tauri dev` loads from the
Vite dev server and is not affected.

## Fix

Move `html { background-color: #000; }` from an inline `<style>` in
`index.html` to `desktop/public/boot.css`, linked via `<link
rel="stylesheet">`. A linked stylesheet is not subject to Tauri's nonce
injection, so `'unsafe-inline'` in `style-src` applies as declared.

The `<link>` is render-blocking (same as the inline style was), so
boot-flash behaviour is identical.

**The production CSP string is unchanged.** This fix makes the policy
apply as intended — no security properties are altered. Will's follow-up
with the security team (Jordan Mecom / Eli Foster, authors of block#4614) is
noted for post-ship.

A Tauri-faithful CSP harness for the Vite dev path (so this class of
regression is visible before a packaged build) is tracked as a separate
follow-up.

## Files Changed

- `desktop/index.html` — replace inline `<style>` with `<link
rel="stylesheet" href="/boot.css" />`
- `desktop/public/boot.css` — new file, the extracted `html {
background-color: #000; }` plus rationale comment
- `desktop/src-tauri/tests/csp.rs` — update comment: nonce for styles,
SHA-256 for the boot script

## Testing

- `just desktop-typecheck` ✅
- `just desktop-test` ✅ (4535/4535)
- `just desktop-tauri-test` ✅ (all Rust tests including `csp.rs`)
- Packaged validation: `pnpm tauri build --debug` completed; compiled
binary bakes `style-src 'self' 'unsafe-inline'` with no nonce source
injected ✅

## Summary

- serialize the relay error-message test with all other tests mutating
the process-wide admission gate
- clear its 300-second rate-limit expiry after the assertion
- prevent the paused-time waiter test from observing another test's
state

## Root cause

`relay::tests::oversized_hint_is_capped_in_relay_error_message_string`
arms the process-wide gate for 300 seconds without taking `TEST_SERIAL`
or resetting it. In a parallel test run,
`relay_admission::tests::concurrent_429_extends_the_window_for_parked_waiters`
can observe that expiry, producing the reported `300.001s` instead of
`5s`.

- focused admission suite + relay error test repeated 10 times
- pre-push `desktop-tauri-checks` passed, including the full Rust
workspace suite
- `branch-skew` passed

## What changed

Bind the development Compose stack's published PostgreSQL, Redis,
Adminer, Keycloak, MinIO, and Prometheus ports to `127.0.0.1`.

## Why

Docker publishes a host port on every interface when no host address is
specified. Running the development stack on a remote workstation or VPS
therefore exposes its infrastructure services to that machine's public
networks. Loopback bindings retain host-local development access and
Docker's internal `buzz-net` connectivity without making those services
Internet-reachable.

## Impact

Local workflows continue using the same ports. Deliberate remote
administration now requires an SSH tunnel or another trusted
private-network path.

## Validation

- `docker compose -f docker-compose.yml config --quiet`
- Recreated the six affected services with their existing named volumes
and Docker network
- PostgreSQL remained healthy and retained all 54 application tables
- Redis, MinIO, and Prometheus health checks passed
- All affected ports were closed on the host's public IPv4 and IPv6
addresses while remaining available on loopback

…starve the handoff summary (block#5248)

## Problem

The handoff summarizer sends `max_tokens: 8192`
(`HANDOFF_MAX_OUTPUT_TOKENS`) with no reasoning budget separation. On
reasoning models, thinking tokens count against that cap: the model can
spend the entire budget reasoning, length-stop with empty `content`, and
`summarize()` — which only reads `content` — reports an empty summary.
The handoff then degrades to lossy history truncation.

Observed on deepseek-v4-flash during a terminal-bench 2.1 run
(tb21-solo-3, 89 tasks): **13 consecutive handoff attempts across 5
trials failed exactly this way** (`handoff returned empty summary;
truncating`), each burning ~3 minutes of full-cap reasoning, before a
stochastically-short reasoning run finally fit. circuit-fibsqrt alone: 5
failures, 5 truncations, then success on attempt 6. video-processing
failed its task by one frame after 3 context truncations.

## Fix

`openrouter_summary_body` now grants reasoning its own equal-sized
budget and excludes it from the response:

- `reasoning.max_tokens = max_output_tokens` — thinking gets a dedicated
budget instead of competing with the summary text
- `reasoning.exclude = true` — reasoning is never in the response body;
`summarize()` only reads `content`
- `max_tokens = max_output_tokens * 2` — the total cap covers both
budgets, so the text budget the caller asked for is actually available
for text

Non-reasoning endpoints ignore the `reasoning` object. Deliberately not
paired with `provider.require_parameters`, for the reasons documented at
`apply_openrouter_mutations` (it hard-404s valid model ids).

The prior test
`openrouter_summary_carries_neither_reasoning_nor_provider` asserted
`reasoning` absent from the summary body — that assertion guarded
against *effort-based* reasoning leaking in from config (the body is
built independently of `cfg`, which is still true and still tested:
`reasoning.effort` stays unset). Replaced with
`openrouter_summary_budgets_reasoning_separately_and_carries_no_provider`.

## Verification

- `cargo test -p buzz-agent`: 422 unit + 110 integration tests pass at
bb2fedd
- `cargo fmt` / `cargo clippy -p buzz-agent --all-targets`: clean
- Not yet validated against a live OpenRouter reasoning endpoint — the
failing scenario needs a long-context session to trigger organically.
Evidence for the mechanism is from run artifacts (13/13 empty-summary
length-stops on deepseek-v4-flash) and OpenRouter's documented
`reasoning.max_tokens`/`reasoning.exclude` semantics.

**Category:** improvement
**User Impact:** Users can create, discover, and import agents from one
consistent Add agent dialog.

**Problem:** Agent creation, discovery, and import were split across a
dropdown and separate dialogs, making the Add agent flow fragmented. The
existing E2E suite also continued targeting the deleted dropdown after
the flows were unified.

**Solution:** Route the new-agent card directly into a unified dialog
with dedicated Create, catalog, and Import navigation, then update the
affected E2E coverage to exercise that interface and its current empty
state.

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

**desktop/src/features/agents/ui/AgentDefinitionDialog.tsx**
Supports rendering the agent definition form inside the unified Add
agent experience while retaining the standalone dialog behavior.

**desktop/src/features/agents/ui/AgentDefinitionDialogShell.tsx**
Adds the shared shell used to present agent-definition content
consistently in embedded and standalone contexts.

**desktop/src/features/agents/ui/AgentDialog.tsx**
Passes the revised dialog state and close behavior through the existing
agent dialog entry point.

**desktop/src/features/agents/ui/AgentsView.tsx**
Connects the Agents page to the unified Add agent dialog and opens newly
added catalog agents in their profile panel.

**desktop/src/features/agents/ui/PersonaCatalogDialog.tsx**
Combines catalog browsing, agent creation, and snapshot import behind
persistent navigation, including dirty-navigation confirmation.

**desktop/src/features/agents/ui/UnifiedAgentsSection.tsx**
Replaces the new-agent dropdown with a direct Add agent entry point and
adjusts the responsive card grid.

**desktop/src/features/agents/ui/personaLibraryCopy.ts**
Updates catalog-facing copy for the unified experience.

**desktop/src/features/agents/ui/usePersonaActions.ts**
Returns the resolved local persona after catalog activation so the
caller can open the added agent.

**desktop/tests/e2e/agent-readiness-screenshots.spec.ts**
Opens the embedded create pane directly for readiness screenshots.

**desktop/tests/e2e/agents.spec.ts**
Covers unified Create, catalog, and Import navigation and asserts the
current shared-agent empty state.

**desktop/tests/e2e/global-agent-config-screenshots.spec.ts**
Updates global configuration screenshot setup for direct create-pane
entry.

**desktop/tests/e2e/inline-custom-harness.spec.ts**
Updates custom harness setup for the embedded create form.

**desktop/tests/e2e/persona-env-vars.spec.ts**
Updates environment-variable and model-provider scenarios for direct
create-pane entry.

**desktop/tests/e2e/persona-model-combobox-screenshots.spec.ts**
Updates model combobox screenshot setup for direct create-pane entry.

**desktop/tests/e2e/smoke.spec.ts**
Updates agent-creation smoke coverage for the unified Add agent dialog.

**desktop/tests/e2e/where-to-run-config.spec.ts**
Updates provider-selection coverage for the embedded create form.

</details>

## Reproduction steps

1. Open the Agents page and select the new-agent card.
2. Confirm the Add agent dialog opens directly on Create without an
intermediate dropdown.
3. Use the left navigation to browse shared agents and open Import.
4. Select a catalog agent and confirm the dialog closes and the added
agent's profile panel opens.
5. Run the affected desktop Playwright smoke and integration specs and
confirm all scenarios pass.

…nchmark agent rounds (block#5318)

## Problem

Two failure modes from the `tb21-glm52-crusoe-1` benchmark run (GLM-5.2
solo, TB2.1) wedged or killed 13 of 89 trials without the model being at
fault:

1. **Conversation poisoning on text-only endpoints.** Crusoe's
serverless `crusoeai/GLM-5.2-NVFP4` rejects any request whose history
contains an image with `400: ... is not a multimodal model`. The
recovery machinery for exactly this case already exists —
`AgentError::UnsupportedImageInput` → `replace_unsupported_images()`
strips the image blocks, marks the tool result as an error, substitutes
a text placeholder, and continues the turn. But classification only
matched OpenRouter's 404 body (`no endpoints found that support image
input`) and was only consulted on the 404 arms. The Crusoe 400 fell
through to terminal `AgentError::Llm`: the image stayed in history,
every subsequent call failed identically, buzz-acp rode its 10-retry
ladder (~40 min), and the trial idled to budget death. Measured blast
radius: **8 trials wedged, 12.7h aggregate idle-after-poison.**

2. **Bounded agent rounds in benchmark trials.** The harness default
`DEFAULT_MAX_AGENT_ROUNDS = 32` ended solo trials mid-work when turns
rotated (thinking-heavy models hit max_tokens rotation fast; 4 trials
died this way). Benchmark trials already have a wall-clock budget as the
real limit — the round cap only converts recoverable rotation into trial
death.

## Fix

- `is_unsupported_image_input_error()` also matches the verbatim `is not
a multimodal model` body. Matcher stays deliberately tight (same
doctrine as `is_context_length_error`): misclassifying a generic 400 as
recoverable would mutate history for an error that removing images
cannot fix.
- Both status ladders — shared `post()` and `openrouter_post()` —
consult it on their 400 arms and return the typed
`UnsupportedImageInput` (OpenAI-compatible providers report this as 400;
a BYOK/passthrough upstream can surface the provider's own 400 through
OpenRouter).
- Harness `DEFAULT_MAX_AGENT_ROUNDS` → `0` (unbounded —
`BUZZ_AGENT_MAX_ROUNDS=0` is the agent config's documented unbounded
value). Per-agent `budget.max_calls` in manifests still overrides.

## Acceptance

- A 400 with the image-rejection body reaches the existing image-strip
recovery path instead of wedging the session — asserted through
`complete()` (covers the return path into the convergence mapper) and at
the `openrouter_post` terminal, both proving single-attempt (a
deterministic capability rejection must never be retried).
- Ordinary 400s stay terminal `AgentError::Llm` (existing negative tests
unchanged).
- Benchmark trials run unbounded rounds by default; python tests updated
for 0-is-legal with a negative arm at -1.

## Verification

- `cargo test -p buzz-agent`: 427 + 18 + 20 + 15 + 8 + 1 + 48 passed, 0
failed (full package, 3 consecutive clean runs)
- `cargo clippy -p buzz-agent --all-targets`, `cargo fmt --check`: clean
- `uv run --extra dev pytest tests/` in harbor-buzz-orchestra: 35 passed
- Pre-push hooks (full workspace rust-tests + desktop-tauri-checks)

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

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

…ock#5324)

The Prompt Context modal (observer feed → check icon under sent
messages) was clipping all content and card right-padding at the dialog
edge.

**Root cause**: `PromptContextDialog` renders inside `DialogContent`,
which is a CSS grid. The child flex wrapper had default `min-width:
auto`, so the widest unbreakable token in the content (64-char hex event
IDs, `Tags: [[...]]` JSON) set the grid track width, blowing it past
`max-w-xl`. `overflow-hidden` then clipped everything at the dialog edge
— including the section cards' right padding.

**Fix**:
- `AgentSessionTranscriptList.tsx`: add `min-w-0` to the `flex
max-h-[85vh] flex-col` wrapper so the grid item can shrink below its
max-content width.
- `PromptSectionAccordion.tsx`: replace `wrap-break-word` with
`wrap-anywhere` on the body text (open and collapsed states) and the
title. `overflow-wrap: anywhere` reduces min-content width, which
`break-word` does not, letting long tokens wrap inside the cards rather
than inflating the track.

The `line-clamp-2` collapsed preview is preserved unchanged.

…ck#5330)

## Problem

The `WelcomeComposerGuidanceLayer` in the `#Welcome` channel was
positioned with `absolute inset-x-0 bottom-full z-[-1]` — outside the
`composerWrapperRef` measurement boundary. `useComposerHeightPadding`
observes `composerWrapperRef`'s block size to set `paddingBottom` on the
timeline scroll container, but the absolutely-positioned layer didn't
contribute to that size. The banner sat directly on top of the newest
message, blocking the thread affordance on that message, and had no
manual dismiss control.

## Fix

**Overlap**: Changed `WelcomeComposerGuidanceLayer` from `absolute
inset-x-0 bottom-full z-[-1]` to `relative` (in normal flow). As a
normal-flow child of `composer-dock`, the layer's full height is now
measured by the ResizeObserver and fed into the timeline's
`paddingBottom`, so the newest message is always fully visible and its
thread affordance is always clickable while the banner shows.

**Dismiss**: Added an `X` close button
(`data-testid="welcome-composer-dismiss-button"`) on the prompt state.
Clicking fires `onDismiss`, which drives `dismissing → hidden`
immediately (same slide-down animation as the auto-dismiss path) and
marks the channel ID as completed in the session ref so the banner does
not reappear on channel re-entry within the session.

**Refactor**: Extracted the banner state machine (refs, timers,
`useEffect`s, and callbacks) from `ChannelPane.tsx` into
`useWelcomeComposerBanner.ts`. This keeps `ChannelPane.tsx` well under
the 1000-line file-size ratchet and makes the state machine
independently testable.

## Changed files

- `desktop/src/features/channels/ui/WelcomeComposerBanner.tsx` —
`WelcomeComposerGuidanceLayer` positioning fix; `onDismiss` prop;
dismiss button; `overflow-hidden` / `mb-0` / `flex-1` cleanup
- `desktop/src/features/channels/ui/ChannelPane.tsx` — remove inline
banner state machine, use `useWelcomeComposerBanner` hook, pass
`onDismiss`
- `desktop/src/features/channels/ui/useWelcomeComposerBanner.ts` — new
hook owning all banner state

## Problem

A provider can return HTTP 200 with a **truncated JSON body** — cleanly
closed connection, correct framing, content cut off mid-value. Both LLM
HTTP loops treated this as a terminal error on the first attempt:
`AgentError::Llm("json: EOF while parsing a value")`, surfaced as code
-32000 at the ACP boundary, killing the agent turn before it produced
anything.

Observed live in a tb2.1 bench trial (write-compressor, tb21-twins-1):
deepseek via OpenRouter returned a truncated body, the agent died
mid-prompt with 0 turns completed, and the trial scored 0 on a provider
hiccup.

Meanwhile the same loops already retry timeouts, 429s, 5xxs, 499s, and
mid-body stream stalls — a truncated-but-complete body was the one
transient upstream fault that fell through to terminal.

## Fix

In both `post()` and `openrouter_post()`
(`crates/buzz-agent/src/llm.rs`): when the fully-received success body
fails `serde_json::from_slice`, `continue` the **existing** retry loop
instead of returning terminal — same `MAX_RETRIES` (3) bound, same
`backoff_with_jitter`. On exhaustion, the error goes through
`terminal_llm_error` so it carries cumulative duration + attempt count
like every other retried failure (previously the `json:` error carried
neither).

`post_anthropic` routes through `post()`, so
Anthropic/OpenAI/Databricks/mesh and OpenRouter are all covered.

## Why this cannot re-run a tool call

Hard requirement: tool calls are not idempotent, and this change must
not introduce any possibility of replaying one.

1. **The retry lives inside the HTTP POST helper, below the parse
boundary.** Tool calls are only ever extracted from a *successfully
parsed* response value
(`parse_openai`/`parse_anthropic`/`parse_responses`, all downstream of
these helpers' `Ok` return). A malformed body never parses, therefore no
tool call was ever extracted from it, therefore nothing downstream of it
ever dispatched.
2. **What is re-sent is the completion request itself** — the identical
`body_bytes` captured once at function entry. Sending a completion
request executes no tools; it asks the model for the next message.
3. **Same safety class as existing behavior.** The loop already re-sends
this identical request on 429/5xx/timeout/stream-stall; this adds one
more transient-fault arm to the same loop with the same bytes.

## Tests

Three new tests mirroring the existing 499/dropped-connection fixtures
(raw `TcpListener` stubs):
- `post_retries_malformed_json_body_and_succeeds` — truncated 200 body
on attempt 1, valid JSON on attempt 2; asserts success and **exactly 2**
server-side requests
- `post_exhausts_retries_on_persistent_malformed_json` —
always-truncated body; asserts exactly `MAX_RETRIES` attempts and a
terminal error carrying `json:` + cumulative/attempt context
- `openrouter_post_retries_malformed_json_body_and_succeeds` — same
recovery through OpenRouter's separate loop

Full `cargo test -p buzz-agent` green at e7a5d7b (430 lib + all
integration targets, 0 failures); `cargo fmt` + `clippy --all-targets`
clean.

Originating conversation: buzz-benchmarking channel, thread 397a992d.

## Summary

- remove the complete Welcome guidance surface when dismissal reaches
`hidden`
- preserve dismissal across the private and starter Welcome channels for
the active identity
- assert the starter channel's actual `welcome-everyone` title on
re-entry

## Why

PR block#5330 introduced two deterministic Desktop E2E failures:

- the inner banner unmounted, but `welcome-composer-guidance-layer`
remained
- the re-entry test expected case-sensitive `Welcome` while navigating
to `welcome-everyone`

The state hook also scoped completion to channel IDs while `ChannelPane`
remounts during navigation. The Welcome guidance is one experience
spanning both Welcome channels, so completion now survives that remount
while remaining identity-scoped.

## Validation

At `b577eb42edffe889f63566f2457eacea720f3593`:

- `pnpm -C desktop typecheck`
- focused Biome check for all four changed files
- E2E build
- both `welcome-everywhere banner` integration tests repeated three
times: **6/6 passed**
- mandatory pre-push desktop check, typecheck, and full desktop unit
suite: **4,535 passed**
- `git diff --check`

##### Fixed the react compiler preset filter to be linear
([#&#8203;1353](https://redirect.github.com/vitejs/vite-plugin-react/pull/1353))

The improved filter in v6.0.3 was non-linear and caused a performance
regression
([#&#8203;1349](https://redirect.github.com/vitejs/vite-plugin-react/issues/1349)).
The filter was changed to be linear to avoid that.

## Summary

- temporarily allow the informational `RUSTSEC-2026-0243` advisory for
the retired `nostr-relay-pool` crate
- document the exact MeshLLM → `nostr-sdk 0.44.1` transitive path and
removal condition
- keep every other advisory and the global dependency policy enforced

## Why an exception

RustSec provides no patched `nostr-relay-pool` release because the
standalone crate was absorbed into `nostr-sdk >= 0.45`. Buzz inherits it
through pinned MeshLLM v0.74. A direct test bump to `nostr-sdk 0.45.1`
removed the retired crate but produced 13 MeshLLM API compilation
errors, so the durable fix requires an upstream source migration rather
than a lockfile update.

This narrow exception restores the required Security check while that
migration is completed. It must be removed once MeshLLM adopts
`nostr-sdk >= 0.45`.

## Validation

- `bin/cargo-deny --locked check --config deny.toml advisories`
- `bin/cargo-deny --locked check`
- `git diff --check origin/main...HEAD`
- mandatory pre-push Rust and desktop/Tauri checks

## Scope

One four-line `deny.toml` addition. No Rust source, lockfile, runtime,
or release behavior changes.

…ock#6456)

Switching channels triggered a full-roster fetch (kind:39002 plus a
kind:0 profile batch with every member pubkey as an author) in the
common case, and several render paths walked the full roster per render.
None of this scales past a few hundred members; the product target is
10k+.

- **Members query staleTime 30s → 5min.** Every membership change the
client can observe already invalidates the key explicitly: live
join/leave system messages for the active channel, member-added/removed
notifications for the current identity, and all membership mutations —
including previously-uncovered direct write paths (moderation kick,
agent-deletion cleanup), which now invalidate through a shared helper.
The 30s window bought correctness we already had and charged a roster
fetch per switch.
- **ChannelMembersBar no longer mounts the roster query for non-DM
channels** — the count renders from the channel summary, and the
private-channel huddle gate accepts `channel.isMember` (derived from the
same kind:39002 event as the roster's self entry).
- **Roster-derived lookups are cached on roster identity**
(`rosterDerivations.ts`): role map, agent-member subset, member/bot
pubkey sets. These were rebuilt O(members) on every live message /
profile re-key. React Query's structural sharing keeps the roster
identity stable, so each derivation computes once per distinct roster.
- **Backend: the kind:0 profile join in `get_channel_members` is capped
at the first 500 members** (roster order). Members past the cap keep
`display_name: None` (UI falls back to pubkey labels and profile
caches); `role=="bot"` agent flags are roster-derived and unaffected.
Full roster pagination is the structural follow-up.
- **Composer keystroke path**: `useCanAddChannelMembers` re-scanned
channels + roster per keystroke; now memoized on data identities,
sharing the cached pubkey set.

### Measured / estimated impact

| metric | before | after |
|---|---|---|
| roster fetches while switching (live trace) | nearly every switch | ≤1
per channel per 5 min |
| roster fetch cost on the wire (live, 51-member channel) | 273ms per
fetch | amortized away |
| kind:0 `authors` filter size at 10k members | ~670KB per request (~67
B/pubkey) | capped at 500 authors (~34KB) |
| warm-switch longtask at 10k members (mock harness, 4× throttle) |
364ms | 318ms |
| per-render roster walks (role map, agent sets) at 10k members |
O(members) per live message | once per distinct roster |

Deferred deliberately: protocol-level roster pagination and removing
`memberPubkeys` from channel summaries (needs relay support).

…ng after leave (block#6458)

Entering Projects fires a large fan: an exhaustive paginated relay
enumeration (projects/repos/tombstones), five 2,000-event work-item
queries plus assignment-operation scans, per-repo activity summaries,
and a local-repository filesystem scan. Measured on a large community
(101 issues / 258 PRs):

| query | measured cost |
|---|---|
| work-items (5 × 2,000-event REQs + assignment scans) | 3.5–3.9s |
| activity summaries | 4.1s |
| repository activity | 1.0–2.2s |
| local repository scan | 1.7s |

Two lifecycle bugs made the fan far more expensive than it needs to be:

- **Freshness windows guaranteed a full refetch on nearly every
re-entry** (60s enumeration, 30s work-items/activity, 10s local scan) —
i.e., the costs above were re-paid on almost every visit. Every local
write path already invalidates its keys explicitly (issue/PR mutations,
project creation, repo sync), so the short windows only served
remote-actor freshness. Raised to 5m/2m/2m with a 30m enumeration cache:
re-entries now paint from cache, and the fan re-runs at most every 2–5
minutes.
- **Leaving Projects left the whole fan running**, competing with the
next surface's channel fetches on the same relay connection. AbortSignal
is now threaded through the enumeration and assignment pagination loops
(optional params — behavior identical without a signal), and leaving the
surface cancels the work-items query. Deliberately NOT cancelled: the
enumeration (the always-mounted sidebar projects section observes it and
its 30m cache is valuable), repo snapshots and local scans (native work
that can't abort — cancelling would discard the finished result and
force the same clones again), and activity summaries (a single bounded
request).

Abort behavior is covered by red-first unit tests on both pagination
loops. Remaining follow-up (out of scope): the queries themselves want a
relay-side aggregate instead of shipping thousands of events to compute
counts client-side.

**Category:** new-feature
**User Impact:** Workflow authors can build filtered, runtime-aware
automations, understand them at a glance, and get a clear warning before
turning on workflows likely to run often.
**Problem:** Workflow setup exposed raw configuration without enough
help composing message templates, filtering triggers, or understanding
saved behavior; activation could also make a broadly triggered workflow
live without explaining its likely frequency.
**Solution:** Batch 3 adds local, deterministic template variables,
trigger filters, and semantic summaries, then refines cards and
activation around configured behavior and a risk-aware warning boundary.
Scheduling remains the already-shipped implementation, advanced
expressions remain lossless, and network-backed identity/message
enrichment stays in Batch 4.

| Message inputs | Trigger filters |
| --- | --- |
| Caret-aware, keyboard-accessible suggestions expose trigger-local
values and safe prior-step outputs in `send_message.text`. | Structured
conditions and validated manual IDs block invalid submission while
preserving advanced expressions. |

| ![Structured trigger

|

| Workflow cards | Risk-aware activation |
| --- | --- |
| Semantic labels, channel-first hierarchy, configured reaction/action
visuals, real step stacks, and compact status controls make behavior
scannable. | Broad message and frequent schedule triggers explain the
risk before **Turn on**; narrowly scoped triggers proceed without
unnecessary ceremony. |

## Reproduction steps

1. Create a message-posted workflow in **Workflows**, add a Send message
step, and type `{{trig`; verify keyboard-selectable variables insert at
the caret.
2. Configure message-text and manual ID filters; verify malformed IDs
block submission and advanced expressions survive Form/YAML transitions.
3. Create a broad message workflow; verify **Back** persists nothing,
**Keep off** saves it disabled, and **Turn on** enables it. Confirm a
narrowly triggered webhook skips the warning.
4. Inspect the saved card; verify its channel, semantic behavior,
configured actions/reaction, real step stack, and status are
understandable without opening YAML.

- Focused workflow regressions passed 59/60 locally; the only local miss
was a 438-pixel macOS snapshot drift, while the checked-in Linux
baseline comes from the failing CI artifact. Repository pre-push gates
and E2E build/typecheck passed.
- A broader 36-test smoke invocation had 31 passes and five unrelated
pre-existing expectation/snapshot failures, so it is not claimed as
fully green. Adversarial fixes are recorded in [round
one](block#6470 (comment))
and [round
two](block#6470 (comment)).

…pec (block#6517)

`biome check` fails with `lint/correctness/noUnusedVariables` on
`ORIGINAL_CONTENT` in `desktop/tests/e2e/empty-edit-delete.spec.ts`,
which fails `pnpm check` (Desktop Core) for **every PR touching desktop
paths** — e.g. it currently blocks block#6460. It presumably landed while
Desktop Core was path-skipped on the introducing PR.

One-line removal; the constant has no remaining references (the
assertions use `RENDERED_ORIGINAL_CONTENT`).

## Summary

Follow-up to block#5644. Cmd +/- had become a text-only zoom: type scaled
while rem-based padding, gaps, widths, avatars, and controls stayed
frozen, which produced cramped layouts (see [#buzz-frontend
thread](buzz://message?channel=a410ffde-c61f-416a-96e0-c296b5f5ecc9&id=1a758115cf07b00c097f6e988553908c045165325a57637519cfa7ed9c9accec)).

Root cause: block#5644 introduced a virtual typography rem so the **Font
size** preference could change text without moving layout — a good
decoupling — but it also routed **Cmd +/- zoom** through that same
px-valued token and pinned the real root at 16px. One decision ("freeze
layout") was applied to two dials that shouldn't share it.

This PR gives each dial one owner and lets CSS compose them:

| Control | Changes | How |
|---|---|---|
| **Cmd +/- zoom** | Everything — true zoom | Scales the real `<html>`
font-size again (`useWebviewZoomShortcuts`) |
| **Font size preference** | Text only | Sets `data-font-size`;
`typography.css` maps it to a unitless `--buzz-type-scale`, mirroring
how density already works |

`--buzz-type-rem` becomes `calc(1rem * var(--buzz-type-scale))` —
rem-relative, so it rides on zoom automatically. Resulting text px = `16
× zoom × scale × token-ratio`. The 13 / 14 / 15px conversation contract
is unchanged at default zoom. Density and the type ramp from block#5644 are
untouched.

The preference module no longer does px math or knows about zoom; the
zoom hook no longer imports the preference module. Net deletion in
production code.

## Validation

- `pnpm test` — 5,308 desktop unit tests
- `pnpm check:px-text`, `tsc --noEmit`, biome
- Playwright: `top-chrome-zoom-clearance.spec.ts` (native-chrome
clearance stays fixed under root zoom),
`inbox-refactor-screenshots.spec.ts` (zoomed row padding now asserts
`4.4px` instead of the frozen `4px`), and both `profile.spec.ts` zoom
tests (composed zoom × preference, cross-window storage reset)
- Before/after screenshots at 140% zoom in the comment below

…ock#6531)

**Category:** fix
**User Impact:** Users can insert mentions earlier in a draft and
continue typing without the caret corrupting the rest of the message.

**Problem:** Caret correction ran after every document change, so typing
a mention before existing text repeatedly advanced across the mention
separator and interleaved spaces into the draft. **Solution:** Limit
correction to the autocomplete settlement it was designed for, with
transaction-level and browser-level regression coverage for known and
unregistered mentions.

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

**desktop/src/features/messages/lib/mentionHighlightExtension.ts**
Restricts trailing-space caret advancement to an armed autocomplete
settlement instead of every document change.

**desktop/src/features/messages/lib/mentionHighlightExtension.test.mjs**
Exercises the real ProseMirror plugin state and verifies mid-draft
mention typing, unknown tokens, end-of-message typing, and
completed-mention separators.

**desktop/tests/e2e/mentions.spec.ts**
Reproduces the reported composer workflow in Chromium and covers the
same corruption path for an unregistered `@token`.

</details>

## Reproduction steps

1. Open a channel and enter `hello world` in the composer.
2. Move the caret between `hello` and ` world`.
3. Type ` @bo`, select `bob` from autocomplete, and continue typing
`abc`.
4. Confirm the composer reads `hello @bob abc world` with the caret
after `abc`.
5. Repeat with an unregistered token such as ` @zzq` and confirm the
existing text remains intact.

## Before / After

| Before | After |
| --- | --- |
| Typing after a mid-draft mention walks the caret through the existing
message. | Continued typing stays after the inserted mention. |

**Category:** improvement
**User Impact:** Buzz-native project, repository, issue, and pull
request links now appear once as compact inline chips, with their
details available on hover.

**Problem:** Buzz-native entity links rendered both an inline chip and a
standalone preview card, repeating the same metadata and adding visual
noise to conversations. **Solution:** Exclude Buzz-native links from the
shared standalone-preview extractor while leaving entity parsing intact
for chip tooltips and preserving external web previews and attachment
cards.

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

**desktop/src/shared/lib/linkPreview.ts**
Stops Buzz-native preview candidates after parsing, including same-relay
git clone URLs that normalize to repository entities, while allowing
external URLs through the existing snapshot path.

**desktop/src/shared/lib/linkPreview.test.mjs**
Covers project, repository, issue, pull request, markdown-labeled,
same-relay clone, and mixed external-link extraction behavior.

**desktop/src/shared/ui/markdown/useMessageLinkPreviews.test.mjs**
Confirms sent messages no longer merge a standalone Buzz entity card
while external sender snapshots still render.

</details>

## Reproduction steps

1. Open a desktop channel containing a `buzz://project`, `buzz://repo`,
`buzz://issue`, or `buzz://pr` link.
2. Confirm the link renders as an inline entity chip without a second
standalone Buzz card below the message.
3. Hover the chip and confirm its entity metadata remains available.
4. Post an external HTTPS link and confirm its web preview still
renders.
5. Paste a same-relay `/git/<owner>/<repo>` clone URL and confirm it
uses the repository chip without a duplicate card.

## Screenshots

| Before | After |
| --- | --- |
| Inline chip plus redundant standalone Project card | Inline chip is
now the sole presentation |

## Verification

At commit `3fa74cdd342ac1f6721b7d56a7f111af31e0e6e9`:

- focused link-preview + Markdown unit suites — 119/119 passed

same-relay clone metadata, ordinary-link presentation, and in-app
navigation
- `cd desktop && pnpm exec tsc --noEmit` — passed
- `git diff --check origin/main...HEAD` — passed
- pre-push hooks — desktop check, TypeScript, and full desktop unit
suite passed

**Category:** new-feature
**User Impact:** Users can keep selected agents addressed across
consecutive messages without retyping their handles.

**Problem:** Repeated conversations with agents require manually typing
the same mentions on every turn, which adds friction and makes
recipients easy to omit.

**Solution:** The composer can now keep agents automatically addressed
per channel, either from the mention controls or after a successful
inline mention. Addressed agents remain visible in the toolbar, apply to
channel threads, survive send failures safely, and never cross community
boundaries.

## Reproduction Steps

1. Open a channel with one or more agents and open the mention picker
from the composer.
2. Select an agent for automatic mentions, then send several messages
without retyping the handle; confirm the agent remains in the composer
control and receives each message.
3. Mention another agent inline, send successfully, and confirm the
agent becomes automatically addressed; use the notification's Undo
action to reverse it.
4. Open a thread in the same channel and confirm the same addressed
agents are available there.
5. Remove an agent from the composer control and confirm later messages
stop addressing it.
6. Switch communities and confirm addressed agents do not carry into the
other community.

## Screenshots

All states below use the dark Buzz theme with a selected lilac accent.

### Addressed composer

Selected agents stay visible at the composer ingress without adding
handles to the draft.

## Why
The ACP prompt puts a machine-specific Workspace prefix before static
base guidance and labels the user-facing agent instruction layer as the
generic System section. Because the cwd varies by launch and worktree,
leading with it reduces reusable prompt-prefix stability.

`[Workspace]` was added in [PR
block#1194](block#1194) as a defensive fix after
a broken `~/.sprout` → `~/.buzz` migration caused agents to scan `$HOME`
and trigger macOS TCC prompts. This change retains that grounding while
shrinking it to the current working directory and moving dynamic
environment context after the static Base prompt.

## What
- Emit the prompt in Base → Workspace → Agent Instructions order
- Reduce Workspace to `Current working directory: <absolute path>`
- Resolve cwd as an absolute native-platform path and preserve Windows
drive/UNC paths instead of checking for a leading `/`
- Emit Agent Instructions for persona and standalone agent instructions
across modern and legacy ACP paths
- Preserve parsing for archived observer frames that used System or the
former Workspace-before-Base order, and align the persona catalog label

## Risk Assessment
Medium-low — this changes prompt framing for every newly created agent
session. Existing archived observer frames remain parseable, and
execution still uses the same ACP working directory. Cwd resolution now
fails clearly instead of substituting `/` when the process directory
cannot be resolved.

Diagnostic profiling on a large community (101 issues, 258 PRs) showed
Projects tab switches taking 2.5–3.6s, dominated by single React commits
of 0.5–1.5s and per-render recomputation — fetch work was already off
the main thread; the cost was building the UI.

### Measured: tab click → painted, per tab

| tab | before | after |
|---|---|---:|
| projects | 3,608ms | 320–580ms |
| repositories | 3,126–3,534ms | 310–410ms |
| tasks | 395–1,101ms | ~115ms |
| reviews | 322–2,603ms | ~96ms |
| activity | 597–741ms | ~148ms |

Single-commit ceiling dropped from 1,541ms to ≤200ms (growth steps
25–40ms). Fixes in profiled-cost order:

- **Profile popover body mounts only while open.** `UserProfilePopover`
carried seven query subscriptions plus interaction hooks per instance
even when closed; grids mount hundreds (five per card in people stacks,
one per row author) — measured **~40ms per card**, the dominant share of
the 1.2s card-tab commits. The always-mounted shell is now just the
Radix root + trigger; trigger markup, hover timing, and keyboard
handling are unchanged, and hover/tooltip event continuity is preserved
because the trigger never remounts.
- **Incremental row mounting.** The first 12 cards / 30 rows render in
the first commit; the rest stream in 36–60-per-frame low-priority
transitions. Grouped lists trim across group boundaries via a pure,
tested slicer; the mounted count survives in-place refetches.
- **Activity feed**: was rebuilt unmemoized on every render,
markdown-flattening every issue/PR/comment body in the community just to
sort and keep 30 items (~360+ flattens per render on the measured
community). Now memoized, and bodies stay raw until after the sort+slice
— 30 flattens, once per data change.
- **Contribution graph** (always-visible rail, so every tab paid for
it): ~180 day cells each wrapped in a Radix tooltip with per-cell Intl
date formatting per render. Now memoized, cells precomputed once per
data change, native `title` tooltips. (The activity-bar segments keep
their styled Radix tooltips — pinned by an existing spec.)
- **Rows/cards memoized with identity-stable props**: per-row selection
arrays were rebuilt per row per render (O(n²) — 258 PRs × 258-item
arrays each render) and are now hoisted and shared; people arrays derive
inside the memoized cards; the rail's stat walk over every issue/PR is
memoized.
- **`content-visibility: auto`** on cards and rows so offscreen entries
skip layout and paint; **tab switches run in a React transition** so the
click stays responsive while the new tree mounts.

Remaining known cost (out of scope): cold-entry data readiness — the
work-item and activity queries ship thousands of events to compute
counts (2–4s on a large community; see the fan-lifecycle PR). The
structural fix is a relay-side aggregate; tracked as follow-up.

## Summary

- downgrade Mobile Huddle authentication and native media configuration
from protocol v3 to the currently deployed relay's v2 contract
- restore the released one-byte relay peer prefix while retaining later
reconnect, roster, and playout-reset reliability fixes
- update Android, iOS, protocol documentation, and focused tests
together

Protocol v2 does not carry v3's occupancy epoch on audio frames, so it
cannot fence the narrow delayed-packet/peer-index-reuse race. This is an
intentional compatibility tradeoff until the relay v3 rollout is ready.

### Related issue

None found.

### Testing

- `just mobile-check`
- `just mobile-test` — 1,661 tests passed
- Android debug build installed and launched on Pixel 10 as
`xyz.block.buzz.mobile.sprout_mobile_profile_settings`; foreground
process verified
- signed iOS Release build installed and launched on iPhone as
`com.buzz.buzzMobile`; running process verified

A live two-device Huddle audio call remains a manual verification step.

Desktop-managed Buzz agents could only use one MCP server
(buzz-dev-mcp). Users who wanted web search or other third-party MCP
tools alongside the built-in local tools had no way to add them — the
desktop flow hardcodes a single MCP command and build_mcp_servers()
always returned a vec of one entry.

Added BUZZ_ACP_EXTRA_MCP_COMMANDS, a comma-separated env var where each
entry is split on whitespace into command + args. build_mcp_servers()
appends each as a separate McpServer after the primary server. Extra
servers do not receive Buzz relay credentials (BUZZ_RELAY_URL,
BUZZ_PRIVATE_KEY) or auth tags — they are third-party tools, not
Buzz-native MCP servers.

The primary mcp_command short-circuit is preserved: if it is empty, no
servers are returned at all, even when extra commands are configured.

This is option 1 from issue block#6023. It unblocks the web-search use case
(e.g. npx -y mcp-remote https://mcp.tavily.com/mcp/...) without desktop
UI changes.

Closes block#6023

Two correctness issues in the extra MCP server path:

1. Server names derived only from the executable stem collided for common
   multi-server configurations. Two wrappers like 'npx -y first-mcp' and
   'npx -y second-mcp' both became 'npx', tripping McpRegistry's duplicate
   check at spawn. Now disambiguate with a numeric suffix (npx, npx-2).

2. split_whitespace() corrupted quoted executable paths and arguments
   containing spaces. Replace with shlex::split, which handles standard
   shell quoting. Malformed entries are skipped with a warning instead of
   being silently reinterpreted.

Also update the config doc comment to document the delimiter/quoting
contract.

Addresses themiguelamador's review feedback.

…e sanitization

Four issues from wesbillman/Carl's review:

P0 — Extra MCP processes received Buzz identity credentials despite the
PR's isolation claim. build_mcp_servers gave extras an empty per-server
env, but buzz-agent's spawn_one cleared and repopulated every MCP child's
environment from PASSTHROUGH_ENV, which includes BUZZ_PRIVATE_KEY,
BUZZ_RELAY_URL, and BUZZ_AUTH_TAG. Added a trusted flag to McpServer and
McpServerStdio; spawn_one now withholds identity credentials from
untrusted servers. The primary buzz-dev-mcp server is trusted; extras are
not.

P1 — BUZZ_ACP_EXTRA_MCP_COMMANDS was absent from Desktop's reserved env
key list, allowing a portable persona or per-agent env to inject an
arbitrary command. Added to reserved_env_keys.rs and its test.

P1 — Malformed quoting logged the raw command (which may contain an
embedded API key) and silently skipped the entry. Now fails closed with
only the entry index; the raw command is never echoed.

P1 — Generated names used the executable stem verbatim, violating
McpRegistry's ASCII alphanumeric/hyphen and 128-byte contract. Added
sanitize_mcp_name to replace non-conforming characters with hyphens,
strip leading/trailing hyphens, and truncate to 128 bytes.
