a362fecc23 perf(desktop): parallelize relay agent directory rebuild (#6258)
The shared-agent directory rebuild resolves runtime directories, owner
profiles, and managed policies for every candidate agent via dozens of
exact-author query batches. Issuing those batches serially made a
~100-agent rebuild take 6.5–8.4s, which dominated @mention autocomplete
latency.

#6224 already scoped the *send-path* revalidation
(`revalidate_relay_agents`) to just the mentioned pubkeys, so the send
stall is fixed. But the autocomplete directory (`list_relay_agents`)
still rebuilds the full membership set serially — this PR removes that
remaining cost.

## Change

Run the query batches with bounded concurrency via a shared
`query_filter_batches` helper. Each directory rebuild constructs one
`tokio::sync::Semaphore` (8 permits) and shares it across all of that
rebuild's phases, so the runtime-directory and owner-profile phases that
run concurrently under one `try_join!` never exceed 8 `/query` requests
in flight together — the bound is per-rebuild. The policy phase reuses
the same budget. Same events, keyed by pubkey downstream so ordering is
irrelevant.

Both `list_relay_agents` (autocomplete) and `revalidate_relay_agents`
(scoped send-path check from #6224) funnel through
`list_relay_agents_for_selection`, so the helper is a no-op for the tiny
1–3-mention revalidation set and only the full autocomplete rebuild sees
the win — the scoped send path is untouched.

## Measurement

Live on the production relay, warm connection, full `list_relay_agents`:

| | Full-directory rebuild |
|---|---|
| Serial (before) | 6.5–8.4s |
| Bounded-concurrency (after) | 2.0–3.4s |

Returned pubkey set is byte-identical pre/post. The 8-permit ceiling
holds under saturation (24 batched requests → peak exactly 8, zero
failures, zero requests left in flight).

121e4b3ce7 fix(desktop): exclude archived agents from nest, order regeneration (#5905)
The managed "Active Agents" table in `~/.buzz/AGENTS.md` was rendered
from every managed-agent record with no filtering, so archived duplicate
instances kept appearing under the active relay's header. This scopes
the roster to identity-active agents and makes regeneration safe under
concurrency.

## Roster filter: identity-archive only

`render_dynamic_section` now drops only records whose pubkey is present
in the relay's `kind:13535` archive snapshot. Local records can't tell
they're archived — they all carry `is_active: true` (that flag is a
*definition*-archive, not an identity-archive), so archive truth lives
only relay-side. The read **fails open**: an unreachable relay yields an
empty set and hides no one.

There is deliberately **no** relay-scope filter. `relay_url` is a legacy
creation-era field that `effective_agent_relay_url()` ignores — every
agent is eligible on every community, and snapshot-imported records
store `relay_url: ""` by design. Filtering on it would hide valid,
runnable agents after a workspace switch or import. Foreign-relay relic
records leave the table via record deletion, not code.

## Regeneration on archive / unarchive

`archive_identity` and `unarchive_identity` submitted the relay event
and returned without refreshing `AGENTS.md`, unlike the ~20 other
mutation sites that call `try_regenerate_nest`. A just-archived agent
therefore lingered on the roster until an unrelated edit or the next
launch. Both commands now trigger a regeneration after a successful
submit.

Regeneration is bound through a `NestRegenTrigger` trait rather than
constructing the `try_regenerate_nest` callback at the Tauri-command
delegation site. The command cores take `regen: &impl NestRegenTrigger`
and own the `|| regen.trigger()` binding; the thin wrappers only pass
`&app` (whose `impl` calls `try_regenerate_nest`). This puts the regen
wiring inside the unit-tested core — a `CountingRegen` double proves
each core fires exactly one regeneration — instead of an untestable seam
where a wrapper could silently lose the refresh while the suite stayed
green. The regen races the relay's `kind:13535` snapshot update, so it's
best-effort and fail-open — a stale render self-heals on the next cycle.

## Ordered regeneration

`try_regenerate_nest` previously spawned unconstrained tasks that each
snapshotted state, awaited two relay requests, then wrote — so a slow
pre-edit generation could overwrite a newer one. Boot made this
deterministic: the boot regen races the `apply_workspace` regen, and the
fallback-relay render could finish last.

`NestRegenGate` fixes this with a single `highest_requested` watermark.
A monotonic generation is claimed *synchronously* at request time
(encoding call order) and advances the watermark under one lock; the
spawned task carries its generation and, at commit, reads the watermark
under that same lock — the compare-and-write is atomic with no await
held across it. A generation whose number is below the current watermark
drops its result instead of rolling the file back.

Gating on highest-*requested* rather than highest-*written* is the
load-bearing choice: if a newer generation is requested but then fails
its relay reads, an older in-flight generation must **not** publish its
now-obsolete roster. Behavior delta: once a newer regeneration has been
requested, no older generation will ever write; if that newer generation
fails, the file is left as-is and self-heals on the next trigger rather
than regressing to a stale snapshot. This is an ordered,
latest-request-wins gate — not a work coalescer: superseded generations
still perform their relay reads and drop the result at commit time.

The gate's commit lock is acquired with a poison-to-`io::Error` mapping
rather than `expect()`, so a poisoned lock degrades to the same
warn-and-continue path as any other commit failure instead of panicking
the desktop process (a best-effort housekeeping write must never take
down the app).

## One relay target per regeneration

A regeneration read the workspace relay override three times — the
NIP-11 signer in `fetch_relay_self`, the snapshot query in
`query_relay`, and the rendered footer — so a workspace switch
mid-flight could pair one relay's advertised signer with another relay's
snapshot, fail open, and render archived agents as active.
`capture_relay_target` now resolves the effective relay (WebSocket +
HTTP API base) once, before any network work, and
`fetch_archived_pubkeys_at` threads that single target through both the
NIP-11 fetch and the `/query`; the footer renders the same target.
Signer, snapshot, and footer always belong to one relay.

## Monotonic archival snapshot publishing

`publish_nipia_archival_list` stamped its `kind:13535` snapshot with a
whole-second `created_at`. A rapid archive→unarchive within the same
second produced two events whose NIP-16 replaceable-event tie-break
(higher event id wins) could strand the older, stale archive state as
canonical. Publishing now uses a bounded retry that re-reads current
archive state and rebuilds the snapshot each attempt, so the published
list reflects the latest intended state rather than a fixed same-second
race loser. After the attempt budget (8) is exhausted the publisher
`bail!`s; the sole caller treats that as a `warn!` side effect and
continues, matching the surrounding best-effort submit path.

## Test-file split

The renderer, `upsert_managed_section`, and the regeneration-gate tests
moved to `nest/render_tests.rs` so each test file stays under the
repository's 1000-line ratchet.

6e8d078ffe fix(desktop): emit camelCase config-write payload fields (#6062)
Fixes #6015.

`ConfigWriteMechanism` is internally tagged and carried only `rename_all
= "camelCase"`. On an internally tagged enum that renames the
**variants**, never the variants' fields, so the payload went out
snake_case:

```
{"type":"respawnWithEnvVar","env_key":"K"}
{"type":"acpSetConfigOption","config_id":"c"}
{"type":"acpSetSessionModel"}
{"type":"gooseNativeConfigWrite","config_key":"g"}
{"type":"readOnly"}
```

against `envKey` / `configId` / `configKey` in
`desktop/src/shared/api/types.ts:615-620`. That output is a probe run of
the real module before the fix, not a reading of the code.

What makes it read as correct is the asymmetry: the variant *names*
rename fine, so the `type` discriminant and every `switch
(writeVia.type)` behave; and the enclosing `NormalizedField`'s own
fields (`writeVia`, `overriddenValue`, `isRequired`) rename fine too,
because `rename_all` does apply to struct fields. Only the variant's
field is wrong.

Adding `rename_all_fields = "camelCase"` fixes it. `rename_all_fields`
appeared zero times in `desktop/src-tauri` before this.

**Severity, stated plainly: latent, not currently user-visible.**
Nothing in `desktop/src/**` reads `.envKey`/`.configId`/`.configKey` off
a `writeVia` — `AgentConfigPanel.tsx` is the only `RuntimeConfigSurface`
consumer and never touches the field, and no Rust code deserializes the
type either. The write-back path these fields exist for is not wired
yet. The hazard is for whoever wires it: `invokeTauri<T>` is an
unchecked cast, so they get `undefined` with a green `tsc`.

I also carried the attribute onto `ConfigFieldType`. Its only payload
field is `options`, single-word, so that half is not a fix — it is the
attribute the next multi-word field would silently need.

One divergence from the issue's suggested step 3: the 20 `e2eBridge.ts`
sites already emit camelCase, and camelCase is the contract, so they are
correct as written — changing them would have been wrong. What they
lacked was provenance, since agreeing with `api/types.ts` while the
backend emitted something else is exactly what let this sit. They now
name the Rust test that pins the bytes.

**Tests** (`wire_format_tests`, 4 cases, whole-value not key-set — a
key-set assertion still passes when a variant name regresses):
- every variant against the TypeScript spelling;
- the nested `NormalizedField`, which is the shape the renderer actually
receives;
- a camelCase round-trip **plus** an assertion that the old `env_key`
spelling is now rejected, so a revert cannot quietly keep deserializing;
- `ConfigFieldType::Enum`.

Removing `rename_all_fields` again turns three of the four red.

Verified locally: full Tauri library suite 2444 passed / 15 ignored / 0
failed; `cargo clippy --manifest-path desktop/src-tauri/Cargo.toml
--workspace --all-targets -- -D warnings` clean; `cargo fmt
--manifest-path desktop/src-tauri/Cargo.toml --all -- --check`; in
`desktop/`: `pnpm typecheck`, `pnpm check`, `pnpm test` 4954 passed;
`git diff --check`. Not run: the app itself — there is no UI path to
this field yet, which is the same reason the bug is latent.

e2ade93f02 fix(desktop): downscale large avatars for agent-share PNG body (#6260)
Sharing an agent encodes a `.agent.png` snapshot with the avatar as the
PNG image body. Non-PNG avatars were transcoded at full resolution and
already-PNG avatars were carried through unchanged, so a large source
avatar could produce a PNG that exceeds the 10 MiB
`MAX_SNAPSHOT_PNG_BYTES` cap and fail the send. A 2764×4096 webp avatar
encoded to ~26 MB — over 2.5× the ceiling — which is why sharing that
agent hung for a few seconds (fetching and transcoding the image) and
then failed.

The share dialog compounded the problem: on failure it discarded the
pipeline's real error (`Snapshot exceeds the 10 MiB size limit…`) and
toasted a generic `Couldn't send … Try again.`, hiding the actual cause.

## Changes

- **Downscale the avatar for the snapshot PNG body.** The body is only a
card thumbnail, so raster avatars are now downscaled to a 512px longest
edge (`MAX_PNG_BODY_EDGE`) before PNG re-encoding, mirroring the
frontend SVG rasterizer's 512×512 cap in `snapshotAvatarPng.ts`.
Already-PNG avatars over the dimension cap route through the same
downscaling transcode path instead of a straight tEXt-chunk injection.
The manifest's `avatar_url`/`avatar_data_url` source reference is
untouched — only the PNG image body is downscaled.
- **Surface the real error in the share dialog.** `PersonaShareDialog`
(used by `SnapshotShareDialog`/`TeamShareDialog`) and
`AgentCardViewerDialog` now toast the send controller's actual error
message, falling back to the generic string only when it is empty. A
`getCurrentError()` accessor reads the error through a ref because the
render-captured `state.error` is stale in the closure immediately after
`beginSend` resolves.

A unit test pins the invariant: an oversize (2764×4096) avatar produces
a snapshot that stays far under the cap with body dimensions clamped to
512px.

50a71137e6 feat(managed-agents): close five Claude Code agent-config gaps (#4557)
Closes five Claude Code agent-config gaps in Buzz Desktop, split into
three commits that share the spawn-time and live-switch surfaces.

## Config isolation, model authority, and Auto mode (#2692, #2884,
#3493)

- **`CLAUDE_CONFIG_DIR` isolation (#3493).** `config_bridge` resolves
both `settings.json` and `.claude.json` panel paths from the agent's
effective env (`resolve_effective_agent_env` — baked floor → definition
→ global → persona → record), so the panel reads the same directory the
agent runs against. `mcp_config_file_path_for_runtime` honors a custom
dir; empty/blank is treated as unset, matching Claude's
`CLAUDE_CONFIG_DIR || homedir()` semantics. `AgentConfigPanel` shows a
Keychain caveat when a custom dir is active (a custom dir maps to a
fresh Keychain namespace unless `CLAUDE_SECURESTORAGE_CONFIG_DIR` is
also set).
- **Single startup model authority (#2692).** `ANTHROPIC_MODEL` is the
sole startup model authority for Claude. Local spawns write
`ANTHROPIC_MODEL` and strip `BUZZ_ACP_MODEL` so the harness never sees
two authorities; remote deploys send `ANTHROPIC_MODEL` in `policy_env`
instead of `BUZZ_ACP_MODEL`. Non-Claude runtimes are unchanged.
- **`PermissionMode::Auto` (#2884).** Wire string `"auto"`, model-gated,
degrades to the agent default when the active model doesn't advertise
it.

## Thinking effort end-to-end for local Claude agents

Effort flows from the running session's discovered `thought_level`
config option through the config surface to a local-only write control
and a read-only two-facts display.

- **Reader.** Discovers the `thought_level` config option from the
session cache (never hardcoded) and populates `effort_config_id` /
`effort_options` on `RuntimeConfigSurface`. The canonical effort tier
orders record env > `record.effort_level` (`BuzzExplicit`) > ACP >
persona > global > definition > file, so the panel shows the effort the
next spawn will launch with while `resolve_with_override` surfaces the
running ACP value as the struck-through override — neither masks the
other silently.
- **Write control.** `persist_agent_effort_level` is a direct-write
Tauri setter (writes `record.effort_level` + `updated_at`,
`save_managed_agents`) that rejects non-local backends — remote effort
is set at deploy time via `policy_env`. `EffortPickerField` mounts in
`AgentInstanceEditDialog` beside the Model block, gated on a local
backend **AND** a discovered `effortConfigId`. It persists directly and
invalidates the config surface, mirroring the
`setManagedAgentAutoRestart` standalone-setter precedent, so the frozen
`UpdateManagedAgentInput` shape stays frozen.
- **Display.** The read-only configured-vs-current two-facts display is
the `thinkingEffort` normalized field in `AgentConfigPanel`, fed by the
reader's canonical tier ordering.
- `buzz-acp` applies the startup effort env at session start.

## Distinguish a rejected model switch from silent success

A live model switch collapsed adapter rejection into success:
`apply_model_switch` returned `Ok` on both an accepted switch and an
application-level refusal, so the caller cached pre-switch capabilities
as if they described the target model and Desktop reported the pick as
landed.

- `ModelSwitchOutcome::{Applied(Value),Rejected}`. Transport-class
errors still propagate as `Err` (respawn the poisoned stdio); an
application-level refusal is now `Rejected`.
- The caller drives everything off `post_switch_snapshot`: `Applied`
refreshes `model_capabilities` from the target model's echoed
`configOptions` (or drops to `None` when none are echoed, so a
pre-switch snapshot is never mistaken for the target's); `Rejected`
preserves pre-switch caps and emits a `failure` `control_result`. Effort
resolution and the session-config capture read the post-switch snapshot
so they converge on the model the session actually runs;
`modelOverridden` is gated on `switch_succeeded`.
- `liveSwitchOutcome.ts` gains a distinct `"failed"` outcome for the
adapter `failure` frame and treats the busy-path `"sent"` ack as
provisional — it never counts toward success. Success is confirmed only
by a real positive terminal frame (the busy-path deferred apply emits a
correlated `switched` `control_result` when it lands), and the fallback
timeout resolves an honest `"pending"` (accepted, apply deferred), never
a false `"ok"`. `ModelPicker` surfaces a distinct toast per outcome —
failed, unsupported, and pending.

## Scope explicitly excluded

Per-agent config dir provisioning, `CLAUDE_SECURESTORAGE_CONFIG_DIR`
sentinel injection, `settings.json` projection, protected-key stripping,
MCP inheritance, spawn serialization, and the `last_spawn_warnings`
surface are absent from this diff. Silent-fallback machinery for
non-Claude runtimes (#2265/#4004) is a tracked follow-up.

## Sanctioned follow-ups

- **Live mid-conversation effort switching.** Effort is spawn-scoped
only in this PR: the worker reads `BUZZ_ACP_EFFORT_LEVEL` once and
applies it at session creation. The live effort-switch machinery
(mid-conversation effort RPC + ack frame) was deliberately removed and
is archived on `archive/claude-config-gaps-live-effort` for a future
plan-gated revival.
- **Idle-path late model-switch rejection is unobservable.** An idle
switch acks `switched` immediately after catalog validation, but the
real `set_config_option` runs at the next session creation — potentially
much later — so a rejection there is not surfaced back to the picker
(holding a subscription that long is not sensible). Pre-existing,
catalog-gated behavior; a durable fix is a tracked follow-up.

Closes #2692, #2884, #3493

3fdf289b78 fix(desktop): bound remote agent mention authorization (#6224)
## Summary

- add a targeted native `revalidate_relay_agents(pubkeys, channel_id)`
command for send-time authorization
- scope membership discovery to the destination channel and selected
pubkeys before runtime/profile/policy queries
- replace full relay-directory rebuilds with targeted checks before
agent side effects and again at publication
- preserve managed-agent evidence independently and retain internal
owner-only filtering

## Security and trust boundary

The targeted command reuses the existing authoritative chain:

1. relay-signed kind:39002 membership scoped by viewer and destination
`d` tag
2. agent runtime directory event
3. agent-signed owner profile verification
4. owner-signed managed policy
5. internal-build `owner_only` filtering before policy lookup and on
final results

Relay-only agents are dropped on any targeted directory failure. Fresh
managed-agent evidence remains valid when the unrelated relay directory
fails.

## Validation

- pre-push gate passed: branch skew, Desktop check/typecheck/tests,
Tauri checks, Rust tests, and mobile tests
- Desktop unit suite: 4,992 passed
- targeted Rust relay-directory tests passed
- focused Playwright mention-send acceptance passed
  - relay-only send emits the expected `p` tag
- exactly two targeted `revalidate_relay_agents` calls on the
already-member send path: pre-side-effect and pre-publication
  - no `list_relay_agents` call on that send path
  - relay failure and revocation remain fail-closed
  - internal owner-only mode hides other-owned agents
- manual local Desktop testing by Wes: mention sends felt materially
improved

## Notes

This intentionally does not clear the composer early or add an
optimistic timeline row. Publication still waits for fresh
authorization.

f0234f1449 fix(desktop): eliminate mounted-view CPU burn — compositor-safe shimmer, observer append fast path, poll-tick disk reads (#6198)
## Summary

Live 0.5.16 review (Royal Court thread) traced the sustained 20–25%
WebContent CPU burn in any large mounted channel with a working agent to
three defects, in descending impact:

1. **Shimmer animation forces per-frame style + compositing walks.**
`.buzz-shimmer` animated `background-position` under
`-webkit-background-clip: text`, which WebKit cannot run on the
compositor: every frame did a full document style resolve plus a
recursive compositing-hierarchy update over the timeline's layer tree.
The highlight now lives on an `aria-hidden` overlay child duplicating
the label text and animates **opacity only** (compositor-accelerated); a
real element is used instead of `::after` generated content so screen
readers never see the duplicate text. Visual: the moving sweep becomes a
gentle pulse. `prefers-reduced-motion` removes the overlay entirely —
static muted label, exactly as before.
2. **Observer journal whole-journal dedup + re-sort per append.** Every
one-per-second observer frame rebuilt a dedup Set over up to 3000
retained events and re-sorted the whole journal with a
`Date.parse`-per-comparison comparator. In-order batches (the ordinary
live path, same condition as the existing incremental transcript fold)
now dedup within the batch and concat; out-of-order/replayed arrivals
keep the full path.
3. **Redundant disk reads in the 5s agent-list poll.**
`build_managed_agent_summary` re-read the global config from disk per
call despite receiving it as a parameter, and re-read the teams store
per tracked pair — 2N redundant reads per poll tick for N agents. Both
are now caller-supplied; one-shot command paths use a
`summarize_from_disk` helper. Same stores, same `unwrap_or_default`
failure posture, read once.

## Evidence (mechanism attribution, live 0.5.16-block, mounted
~1500-event channel)

- True-idle mounted view (working-state UI live): **25.08% mean / 24.15%
median** WebContent CPU; post working-state decay: **6.33% / 3.50%**.
- Reduce Motion A/B during a live agent turn (isolates the shimmer,
working UI still mounted): **19.50% mean → 5.39% mean** (72% collapse).
Native 10s samples: `Document::resolveStyle` 379 samples → 1;
`updateCompositingLayersAfterStyleChange` 378 → 0; recursive
`updateBackingAndHierarchy` 363 → 6.
- The shimmer mechanism predates 0.5.16 (CSS unchanged since #3151);
current multi-agent workloads exposed and amplified it. The mention
regression itself was fixed separately in #6182.

## Testing

- `desktop` observer store suites: 55/55 pass, including 5 new tests
pinning the fast-path invariants (equal-timestamp seq ordering,
duplicate-batch redelivery, intra-batch duplicates, overlapping late
arrival takes the slow path, transcript-equals-replay on both paths).
- `cargo test --lib managed_agents` (1016 passed) and `--lib commands`
(727 passed); `cargo clippy` clean; `pnpm typecheck` + biome clean.
- Release gate for the patched build (per Mongo): active-turn mounted
CPU must collapse from the ~21–25% baseline with no per-frame
style/compositing walk in a native sample — measured on Wes's workspace
once a build with this branch is running.

ee992ff082 fix(desktop): restore release agent mentions (#6182)
## Summary

- preserve OSS relay-agent mentions under shared channel and agent
policy
- restrict owner-only release builds to relay agents with
cryptographically verified ownership matching the current user
- remove the remote policy replay loop that repeatedly rebuilt the relay
directory, while retaining focused polling and send-time revalidation
- query relay profiles and managed policies by exact author coordinates
to prevent noisy events from crowding out valid agents

## Diagnosis

The packaged Block release compiles
`BUZZ_DESKTOP_BUILD_AGENT_ACCESS_OWNER_ONLY`, while ordinary OSS/dev
builds do not. Relay-discovered agents were filtered as if all remote
agents were outside that owner-only boundary, so a same-owner agent
running on another machine disappeared in the release even though the
OSS path could look healthy.

The fix uses the NIP-OA-authenticated owner from the relay directory as
the cross-machine proof. Internal builds admit only verified same-owner
agents and fail closed for missing, mismatched, stale/revoked, or
unavailable ownership evidence. OSS builds retain shared channel/policy
behavior.

## Validation

- desktop focused unit coverage: 39 tests passed
- desktop typecheck and focused static checks passed
- focused Tauri Rust policy/directory tests passed
- production-style E2E build succeeded
- targeted Playwright mention scenarios passed:
  - owner-only release hides other-owned relay agent
  - owner-only release shows verified same-owner relay agent
  - OSS build shows shared `anyone` agent
- repository pre-push hook passed on
`4d40b6e5bb032f2c0755127172c50dee213f65a3`:

f8692fa9b5 test(desktop): cover exact workflow batch limit (#6168)
## Summary

- retain explicit regression coverage for the exact 128-channel relay
request limit
- cover the 129-channel split into 128 + 1 filters

The workflow-listing implementation originally carried by this PR landed
through #6009. This branch is now rebased onto current `main`, so the
remaining diff is only the boundary test that #6009 did not include.

Fixes #6116

## Test plan

- `cargo test --manifest-path desktop/src-tauri/Cargo.toml
workflow_queries_respect_relay_explicit_channel_limit`
- pre-push hook: Desktop checks, Desktop tests, Desktop Tauri checks,
and path-scoped Rust tests

f7a01bda7b fix(workflows): preserve multi-channel listing semantics (#6009)
**Category:** fix
**User Impact:** Workflow listings reliably include every accessible
channel, including for users with more than 128 memberships and when
connected to older relays.
**Problem:** Multi-value `#h` filters could lose live delivery, apply
channel scoping after SQL limits, mishandle partial authorization or
revocation, and permit unbounded membership work. Desktop also submitted
every channel in one request, exceeding the relay's new 128-value safety
bound.
**Solution:** Preserve NIP-01 OR semantics across relay query, count,
and live-subscription paths while enforcing authorization and bounded
explicit-channel work before database or Redis operations. Desktop keeps
the older-relay-compatible one-channel-per-filter shape, sends filters
in bounded batches, combines responses, and deduplicates signed events
by event ID.

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

**crates/buzz-db/src/event.rs**
Distinguishes authorization channel scopes from explicit `#h` scopes in
list and count SQL so requested channels are applied before limits
without implicitly including global rows.

**crates/buzz-relay/src/handlers/req.rs**
Shares explicit-channel scope extraction and limits, preserves valid OR
siblings when malformed branches cannot match, repairs request-local
membership misses, and registers authorized live subscriptions per
channel.

**crates/buzz-relay/src/handlers/count.rs**
Applies the same bounded explicit-channel authorization to COUNT and
preserves channel scope when a multi-channel request narrows to one
authorized channel.

**crates/buzz-relay/src/api/bridge.rs**
Brings HTTP query and count behavior in line with WebSocket semantics
before SQL execution and rejects over-limit explicit-channel requests
before membership I/O.

**crates/buzz-relay/src/subscription.rs**
Indexes multi-channel subscriptions by every authorized channel and
shrinks, rather than destroys, their scope when one channel is revoked.

**crates/buzz-relay/src/handlers/side_effects.rs**
Releases only revoked channel topics and sends terminal closure only
when no authorized channel remains.

**crates/buzz-test-client/tests/e2e_relay.rs**
Adds ignored relay integration coverage for multi-channel delivery and
valid historical/live behavior with malformed or empty OR siblings.

**desktop/src-tauri/src/commands/workflows.rs**
Builds one single-channel filter per membership, submits at most 128 per
relay request, combines batches, and deduplicates by immutable signed
event ID.

**desktop/src-tauri/src/commands/workflows_tests.rs**
Covers filter compatibility, malformed input, 129-channel batching, and
cross-batch event-ID deduplication.

</details>

## Reproduction steps

1. Join multiple channels containing workflows, open **Workflows**, and
confirm workflows from every accessible channel appear.
2. Repeat with more than 128 memberships and confirm the listing remains
complete rather than failing the relay request.
3. Send a multi-value `#h` query/count and confirm only requested
authorized channels affect SQL limits and counts.
4. Subscribe to channels A and B, revoke A, and confirm B continues
delivering live events.
5. Subscribe with a valid channel branch plus a malformed or empty `#h`
sibling and confirm valid history, EOSE, and post-EOSE live delivery
still occur.

## Validation

At pushed head `c419a923f05e483ab26c006a0b3a80cfb3c73844`:

- Relay request tests: 53 passed.
- Desktop full Rust unit suite: 2,468 passed, 17 ignored.

- Pre-push Rust tests and Desktop Tauri checks passed.
- Rust formatting and `git diff --check` passed.

57feca2f20 fix(desktop): repair dropped team membership links at boot and on edit (#5904)
Two membership-propagation defects let an agent team silently lose
members — both observed live on Will's store (Sietch Tabr), not
hypothetical.

**Stale `persona_ids` dropped on save.** Team records written before
persona ids were namespaced hold bare slugs (`thufir`) instead of the
namespaced id (`sietch-tabr:thufir`). Nothing rewrites them, and the
interactive save path (`ensure_persona_ids_are_active`) *drops* any id
it cannot resolve — so the next in-app save shrinks the team. This nuked
four of five Sietch Tabr members.

**`team_id` drifts from team membership.** Team instructions are
injected at spawn by matching `record.team_id`
(`spawn_snapshot::effective_team_instructions`), so an instance's
binding must track its persona's membership. It drifts two ways: adding
a persona to a team leaves the persona's already-running instances at
`team_id: null` (a member in the roster but not in behavior — seen
twice, Gurney and Hayt), and removing a persona while keeping its agents
leaves the kept instance bound to a team that no longer lists it (still
drawing that team's instructions at spawn).

## Fix

A boot migration (`migration/team_membership.rs`) heals existing stores
in one pass over `teams.json` + `managed-agents.json`:

- **Rewrite stale ids.** A stale id is one no definition slug resolves.
Its target is the definition whose `source_team_persona_slug` equals the
bare slug, scoped to the team's source team (via `source_dir` for a
directory-backed team, or the unique `source_team` among resolvable
members for a detached one). Rewrite only when exactly one candidate
matches; zero or many leave the id in place — strictly safer than the
save path, which drops it.
- **Repair `team_id`.** Backfill an instance whose persona is a team
member but whose own binding is unset, and heal a stale binding whose
team no longer lists the persona (re-point when exactly one *other* team
claims it, otherwise unbind). Both directions gate on single-team
evidence — a persona spanning several teams has none (JSON team order is
not ownership), so it is left as-is and logged. A binding whose team
still lists the persona is authoritative and never touched.

Runs BEFORE `detach_directory_backed_teams` (so a not-yet-detached team
can still be scoped by its `source_dir`) and before any UI save can drop
an id. Rewrite-or-leave converges to a fixed point, so a second boot is
a no-op; the store is backed up once before either write.

The edit path (`commands/teams.rs`) propagates a membership change to
live instances immediately, without waiting for the next boot, scoped to
the delta between the pre-edit and post-edit rosters:

- **Added personas** (on the team now, not before) backfill `team_id` on
their unbound instances. An explicit add is legitimate binding evidence
even for a persona shared across teams — unlike the order-blind boot
case.
- **Removed personas** (on the team before, not now) clear `team_id` on
instances bound to *this* team (bindings to other teams are untouched),
so a "keep agents" removal stops feeding a kept instance the old team's
instructions.
- **Delta-scoping keeps a metadata-only edit inert:** with no roster
change, no instance is re-pointed — a shared unbound persona is never
silently bound to whichever team was edited last.

Propagation is best-effort after the authoritative `save_teams`
(mirroring `retain_team_pending`): the team already exists on disk, and
boot repair is the designed retry for a stale/unset binding, so a
secondary `managed-agents.json` write failure no longer fails a command
whose team write succeeded — which would otherwise let a UI retry mint a
duplicate team.

edc4a09aaa feat(workflows): add responsive library card actions (#6008)
**Category:** improvement
**User Impact:** Users can scan what each workflow does and trigger,
edit, duplicate, enable, disable, or delete it directly from the
library.
**Problem:** The workflow list buried common actions and did not expose
each automation's trigger-to-action shape at a glance.
**Solution:** Add a responsive workflow library with a persistent create
tile, compact trigger/action diagrams, prominent workflow titles with
supporting descriptions, and shared card actions while preserving
existing detail, editor, and run-history entry points. Card toggles
refresh both list and open-detail caches so status and definition stay
consistent.

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

**desktop/src/features/workflows/ui/WorkflowActionsMenu.tsx**
Adds a shared card menu for trigger, edit, duplicate, enable/disable,
and delete actions.

**desktop/src/features/workflows/ui/WorkflowCard.tsx**
Reworks cards around the prototype's visual hierarchy: color-coded
trigger, action flow, sentence-case eyebrow, prominent title, supporting
description, status, channel, and update date without a footer clock
icon.

**desktop/src/features/workflows/ui/WorkflowsView.tsx**
Adds the responsive grid, create tile, mutation wiring, and list/detail
cache invalidation. Container breakpoints keep cards two-across at
medium widths and three-across in the 1280px desktop layout.

**desktop/src/features/workflows/ui/workflowDefinition.ts**
Adds immutable enabled-state updates plus narrow trigger and
first-action readers used only to select card icons.

**desktop/src/features/workflows/ui/workflowDefinition.test.mjs**
Covers neutral icon selection, enabled-state immutability, and status
presentation.

**desktop/tests/e2e/workflows.spec.ts**
Covers the create tile, title/description hierarchy, selected-card
enable/disable consistency, and deterministic narrow/medium/wide
captures while retaining existing action coverage.

</details>

## Reproduction steps

1. Open **Workflows** and confirm the create tile stays first as cards
flow from one to three columns with available width.
2. Confirm each card shows a sentence-case trigger eyebrow, prominent
workflow title, supporting description when present, status, channel,
and update date without a clock icon.
3. Open a card's overflow menu and trigger, edit, duplicate,
enable/disable, or delete the workflow.
4. Leave the detail panel open while toggling and confirm its badge and
JSON definition update with the card.

f716eef437 fix(desktop): enforce shared agent access across devices (#6086)
## Summary

- discover shared managed agents from authenticated relay directory
records instead of treating channel membership as sufficient proof
- publish and refresh access-policy changes immediately so running
clients converge across machines without a restart or five-minute poll
- route profile edits through the exact managed instance and
stop/restart runtimes around access changes so unrelated edits cannot
silently widen access
- keep mention send-time revalidation and Block owner-only build
enforcement fail closed
- explain invalid custom provider/model configuration instead of leaving
Save silently disabled

### Related issue

Fixes #3204

### Known residuals

- a brand-new remote agent's first policy record can wait for the
bounded directory poll when no authenticated directory coordinate exists
yet; send-time mention revalidation remains fail closed
- a failed remote-provider policy redeploy is recorded but cannot
undeploy the older provider instance until the provider protocol gains
the destructor tracked by #5570

### Testing

- full Desktop unit suite: 4,961 tests passed
- focused profile editor Playwright workflow passed, including Customize
access edits and prompt-only edits after tightening an instance
- Desktop TypeScript, Biome formatting, file-size ratchet, Tauri checks,
and pre-push suites passed
- independently reviewed for authenticated directory trust, live
subscription teardown, runtime revocation ordering, fail-open edit
paths, and per-agent provider deployment serialization

122a8b8988 Projects v3: unify sharing, discussions, and issue ownership (#5792)
## Summary

Projects v3 makes repository work shareable, discussion-aware, and
easier to scan in one coherent workspace. People can copy canonical
links, reopen the exact workspace tab, understand issue and pull-request
context at a glance, find related channel conversations, and assign or
unassign issues across Desktop and CLI.

- **Unified workspace** — top-level sections sit above repository
controls in one rounded workspace, with navigation positioned close to
the page heading. README and Files retain branch selection; every
section has a labeled icon header, and Issues and Pull Requests expose
creation from a consistent right-aligned action.
- **Repository management** — the repository selector is always
available, including single-repository projects. Its integrated add flow
lets project owners create a repository manually or select an existing
repository without a separate toolbar button.
- **Readable work-item lists** — issue and pull-request rows use
plain-language context instead of opaque metadata. Files, commits,
issues, pull requests, channels, and contributors share consistent row
density and right-aligned timestamps, while deterministic
fallback-avatar colors keep participants distinct on light backgrounds.
Inbox pull-request metadata wraps between complete phrases and truncates
long channel names instead of compressing copy into narrow columns.
- **Reliable entity links** — projects, repositories, issues, pull
requests, and commits have canonical `buzz://` links, preview cards, OS
deep-link routing, and tab-aware navigation. Reopening the same link
re-applies its destination instead of leaving the user on a locally
selected tab.
- **Related conversations** — repository and work-item views surface
channels discussing the current entity, including participants, channel
navigation, message context, and an explicit notice when discovery
reaches its 500-result cap.
- **Reversible issue ownership** — trusted assignment and unassignment
events work across Desktop, Tauri, `buzz-sdk`, and `buzz issues`.
Assignees appear in project views and the assigned inbox, while
authorized users can remove assignments directly from the assignee row.

Assignment state is derived chronologically from labeled Nostr notes.
Issue authors and repository owners may change any assignee; other users
may only assign or unassign themselves. Shared golden fixtures keep
entity-link grammar and validation aligned across TypeScript and Rust.

The branch also updates `webbrowser` to the patched release for
RUSTSEC-2026-0257.

f086eb6544 fix(link-previews): send while previews finish in background (#5697)
**Category:** fix
**User Impact:** Messages send immediately after submission while link
previews finish in the background, with an option to skip delayed
preview preparation.

**Problem:** Waiting for link-preview metadata or snapshot uploads kept
the composer occupied after users pressed Send, while races between
completion, timeout, and cancellation risked inconsistent payloads.
**Solution:** Freeze and promote speculative preview work into a bounded
background send task, clear the composer immediately, and
publish exactly once with prepared previews or gracefully without them
when skipped, failed, or timed out.

3. Let preparation finish and confirm one message is published with its
preview.
4. Repeat and choose **Skip**; confirm one message is published without
waiting for the preview.
5. Simulate preview failure or timeout and confirm the message still
publishes once without preview tags.

207154706c fix(desktop): support channel message path links (#5889)
## Summary

- accept `buzz://channel/<uuid>/<64-hex-event-id>` as a compatibility
message deep link
- activate the desktop window and route path-form message links through
the existing durable message-navigation queue
- support the same path form when rendered or pasted inside Buzz, while
canonicalizing composer output to `buzz://message?...`
- retain the existing one-segment channel-link behavior and reject
malformed event IDs or extra segments

## Context

Buzz Desktop 0.5.11 has no native `channel` route. The recently merged
channel-link handling on main recognizes `buzz://channel/<uuid>`, but
rejects the externally shared `<channel>/<event-id>` form before window
activation. On macOS that presents as Buzz taking the menu bar while its
window neither foregrounds nor navigates.

## Test plan

- `cargo test --manifest-path desktop/src-tauri/Cargo.toml
parse_channel_deep_link`
- focused channel-link, composer-link, and markdown unit tests
- `pnpm typecheck`
- mandatory pre-push hook: desktop checks, full desktop unit tests, and
Tauri/Rust checks

Installed-app external-open behavior requires a build containing this
change; 0.5.11 cannot exercise it because that release predates native
channel-link handling.

**Category:** improvement
**User Impact:** Buzz channel, message, repository, pull request, and
issue links now open reliably and display recognizable context in the

**Problem:** Buzz links could appear as raw or ambiguous URLs, and
navigation links received during startup or community transitions could

particular required hover context to understand at a glance.
**Solution:** Queue desktop channel/message navigation until the UI is
ready, then render bare Buzz permalinks as icon-prefixed chips with
concise entity context while preserving user-authored Markdown labels as
ordinary links.

## Reproduction steps
1. Run the desktop app and open a channel containing bare
`buzz://channel`, `buzz://message`, `buzz://repo`, `buzz://pr`, and
`buzz://issue` URLs.
2. Confirm each bare URL renders as one cohesive chip with a type icon,
a useful name or shortened identifier, and no duplicated channel `#`
character.
3. Add an authored Markdown link such as `[design
discussion](buzz://issue?...)` and confirm the supplied label remains an
ordinary link rather than becoming a chip.
4. Select channel and message links and confirm they navigate correctly
in warm and cold-start states.

34a7f2fb91 Unify agent profile content (#5788)
## Summary

- remove synthetic preview runtime and configuration data so profiles
show only real agent content
- simplify model settings to the effective values and restore bare
section icons
- make owned-agent profiles resolve to the same current persona instance
from every entry point

## Why

Agent profiles opened from DMs or channels could fall back to a partial
declared-owner view instead of the full managed-agent profile shown on
the Agents page. Test preview content and configuration provenance also
remained visible after the redesign.

## User impact

Owned agent profiles now expose the same actions, runtime, channels,
memories, and configuration regardless of where they are opened.
Profiles no longer synthesize preview data, and model settings use the
same simple title/value hierarchy as the rest of the panel.

## Validation

- `pnpm --dir desktop check`
- `pnpm --dir desktop build:e2e`
- focused unit tests: 10 passed
- profile entry-point integration tests: 2 passed
- configuration screenshot suite: 7 passed, with six visually distinct
captures

Snapshots are attached in a PR comment.

## Summary
- state that only `buzz messages send` messages are spoken in a huddle
- require the first tool call after being addressed to be a brief spoken
pickup
- explicitly override the normal no-bare-acknowledgment rule and bound
follow-up speech
- pin those invariants in the prompt test

## Test plan
- `cargo test --workspace` from `desktop/src-tauri`
- pre-push `desktop-tauri-checks` (clippy and full workspace tests)

068a83b097 feat(huddle): cut voice-turn time-to-first-audio from ~1.0 s to ~0.35 s (env-gated latency levers) (#5671)
## Overview

**Category:** feat (env-gated experiment + one exact always-on
optimization)
**Problem:** Speech-end -> first TTS audio through the desktop huddle
pipeline measures **924–1087 ms** on an M4 Max with a 0 ms LLM leg.
Voice turns feel sluggish no matter how fast the agent replies. Baseline
breakdown: ~300 ms hardcoded VAD silence flush + ~150–250 ms Parakeet
decode + ~380–550 ms TTS synthesis before the first player append.
**Outcome:** With all levers enabled, e2e time-to-first-audio measures
**347–384 ms** (307–357 ms on a longer utterance) on the same hardware,
harness, and production pipelines. Defaults preserve production behavior
everywhere except one deterministic, bit-exact cache win.

## What's in here

### Levers (all default-off, env-gated)

| Lever | Env | Effect (measured medians, short utterance) |
|---|---|---|
| Speculative Parakeet decode | `BUZZ_STT_SPECULATIVE=1` | STT leg ->
~max(flush, decode) |
| Streaming TTS synthesis | `BUZZ_TTS_STREAMING=1`,
`BUZZ_TTS_EMIT_FRAMES` | first audio 380–550 -> 211–320 ms (emit=12,
bit-exact) |
| ONNX intra-op threads | `BUZZ_STT_THREADS`, `BUZZ_TTS_THREADS` | TTS
first audio 211–320 -> 129–180 ms (4 threads) |

- **Speculative decode** starts the Parakeet decode at the *first*
silent VAD frame, overlapping it with the flush window. Resumed speech
invalidates the result (voiced-frame-count check); held silence emits it
instantly at the flush boundary.
- **Streaming TTS**: new `synth_chunk_streaming` (buzz-voice)
interleaves the Flow LM frame loop with incremental *stateful* Mimi
decoding, emitting PCM deltas to the player via the existing
`PlaybackChunkAudio` decoration. At `emit_frames=12` (the decoder's
native chunk) streamed audio is **bit-identical** to the batch path —
verified by the ignored test
`incremental_stateful_decode_matches_batch_decode` (max|diff|=0).
Smaller deltas are faster but diverge (~23 dB SNR; decoder intra-chunk
lookahead), hence the default of 12.

> **Removed after live testing:** the `BUZZ_STT_FLUSH_MS` flush-window
override. Lowering the silence window below natural mid-sentence pauses
(the fast-path recipe said 150 ms) split single spoken sentences into
multiple messages and confused the listening agents. The window is a
turn-taking quality knob, not a latency lever — it is now fixed at the
production 300 ms value.

### Push-to-talk grouping fix (always-on)

A held push-to-talk shortcut is an explicit "I am not done talking"
signal, so silence never ends the utterance while it is held — even when
the microphone is also manually open. The utterance flushes on shortcut
release (existing transmit-edge flush); a manually open mic with the
shortcut up keeps normal VAD pause flushing. Gate is the pure
`vad_flush_allowed` function with a unit-test truth table.

### Always-on (exact): voice-conditioning cache

Phase profiling (`BUZZ_TTS_PHASE_LOG=1`) showed a fixed ~160 ms
`condition_voice` Flow-LM pass on *every* chunk, re-deriving the same
post-conditioning state for the same reference voice. The state is now
snapshotted after first computation and restored per chunk (dtype-tagged
tensor copies, keyed identically to the existing `cached_voice`).
Deterministic — same tensors in, same tensors out. The default path's
TTS leg drops from 380–550 ms to 225–355 ms with no configuration.

### Bench harness

`huddle::latency_bench` (`#[cfg(test)]` + `#[ignore]`) drives the real
`SttPipeline` and `TtsPipeline`, feeding a 48 kHz WAV in real-time 100
ms batches (AudioWorklet cadence) with a configurable fake LLM in place
of the relay leg, timing speech-end -> transcript -> speak() -> first
accepted player append.

```
BUZZ_STT_SPECULATIVE=1 BUZZ_TTS_STREAMING=1 \
BUZZ_TTS_THREADS=4 BUZZ_STT_THREADS=2 \
BUZZ_BENCH_WAV=<48k f32 mono wav> \
cargo test --release -p buzz-desktop --lib huddle::latency_bench -- --ignored --nocapture
```

## Tradeoffs to weigh before promoting any lever to a default

- **Speculative decode**: the speculative buffer has ~1 silent tail
frame vs ~19; observed one CTC wobble ("fail" vs "failed") in 24 turns.
Mitigation if productionized: zero-pad the speculative buffer to match
the flush-path shape.
- **Threads**: defaults stay 1 pending the min-spec (4-core Intel) A/B
flagged in the existing `STT_NUM_THREADS` comment.
- **Streaming at emit<12** is NOT the same waveform — don't ship below
12 without an ear pass.

## Validation

- Full desktop lib suite: **2408 passed / 0 failed** at this head
(`18fab2e1c`).
- buzz-voice suite green; bit-exactness test passes against the
production batch decode.
- Defaults-only bench rerun stays in the baseline family everywhere
except the exact conditioning-cache win (stt 525–532, tts 225–355).
- `cargo clippy --workspace --all-targets -- -D warnings` + fmt clean
(pre-push hook battery green).

Measurement notes with per-lever logs: Eva's workspace,
`RESEARCH/HUDDLE_E2E_LATENCY_OPTIMIZATION_2026_08_12.md` +
`RESEARCH/HUDDLE_E2E_STT_FAKELLM_TTS_BASELINE_2026_08_12.md`.

## Suggested promotion order

1. Conditioning cache (in this PR, always-on, exact).
2. Streaming TTS at emit=12: bit-exact audio, biggest UX win — needs the
env-gate removed + barge-in soak + an ear pass on a real huddle.
3. Speculative decode with silence padding: near-free ~100–150 ms.
4. Threads: after min-spec A/B.

2693e0db1f Make workflow run history authoritative in Desktop (#5780)
## Summary

- persist stable workflow run `error_code` values separately from human
diagnostics
- expose NIP-98 authenticated, channel-authorized run history and
approval reads with stable keyset pagination
- connect Desktop to those authoritative reads and return the
relay-created run ID on trigger
- show truthful loading, failure, and pending-trace states, and do not
render approval actions from non-actionable stored hashes

## Validation

- pre-push `branch-skew`, `desktop-typecheck`, `desktop-test`,
`rust-tests`, `desktop-tauri-checks`, and `desktop-check` all passed on
`a097dbe5f`
- Desktop tests: 4,761 passed, 0 failed
- `cargo check -p buzz-relay`
- `git diff --check`

## Remaining gate

This does not claim a relay-backed Playwright workflow journey. The
browser relay bridge still routes workflow invokes through in-memory
handlers; that production-shaped acceptance gate remains follow-up work
before Workflows can leave preview.

a96af89526 Harden shared agent instruction review (#4220)
## Summary

- render shared-agent instructions as literal text so Markdown cannot
conceal spoiler contents, link destinations, or image sources
- reject non-reviewable Unicode controls at every agent-definition
boundary while preserving legitimate rendered emoji sequences
- verify shared catalog event IDs and signatures before trusting
authorship, coordinates, pagination, or executable content
- preserve the exact system-prompt bytes between review and execution
instead of silently stripping or normalizing content

## Security rationale

Shared system prompts are executable configuration. Previously, catalog
prompts were projected through the chat Markdown renderer, which could
hide text, replace link destinations with benign labels, and turn image
syntax into remote loads. Zero-width and bidirectional controls could
also make reviewed text differ from what the agent executes.

This change establishes a review invariant: the prompt a user sees is
the prompt the agent executes. Definitions that cannot be reviewed
faithfully are rejected rather than rewritten. Catalog events must also
pass Nostr ID/signature verification before they can claim a publisher,
coordinate, or cursor.

## What changed

- catalog instructions render as exact literal text rather than rich
Markdown
- catalog relay events are verified on a fresh wire-shaped object before
paging, coordinate selection, attribution, or projection
- forged content, pubkeys, signatures, and invalid newer heads are
ignored and cannot shadow a valid signed definition
- TypeScript catalog parsing rejects unsafe remote definitions before
they reach the UI
- shared Rust validation covers persona create/update/import, inbound
relay sync, definition-less managed-agent sync, and catalog publication
paths
- definition-less managed agents now fail closed on local create, local
update, and publication before persistence or relay retention
- linked managed agents validate their local name while treating the
persona definition as authoritative; their inert record-level prompt is
not executed or published
- names reject layout controls; prompts retain ordinary newlines and
tabs
- legitimate emoji composition is supported, including contextual VS16,
ZWJ, skin-tone, family, flag, and keycap sequences
- detached selectors/joiners, bidirectional controls, tag characters,
zero-width concealment, and other default-ignorables remain rejected
- names are bounded to 128 characters and prompts to 64 KiB
- contributor guidance documents the byte-for-byte review requirement
for future sharing paths

Validation reports the offending code point and never silently removes
it.

## E2E recording


[buzz-shared-agent-security-e2e.webm](https://github.com/user-attachments/assets/44d6b75f-0877-490f-bda4-a716fae3f700)

The recording demonstrates:

- a safe definition remains visible
- a prompt containing zero-width `U+200B` is rejected
- a name containing bidi override `U+202E` is rejected
- the prompt is preserved exactly
- spoiler, link, and image syntax remains literal and does not render or
load

## Verification

Passed locally:

- `just test`: all 10 unit and Docker-backed integration stages
- desktop frontend unit suite: 4,295 tests
- persona catalog relay unit suite: 32 tests, including forged-event and
cursor-shadowing cases
- focused Rust definition-validation coverage: 3 local create/update
tests and 6 publication-filtered tests
- complete desktop Tauri library suite after rebase: 2,263 passed, 14
ignored, 0 failed
- desktop Tauri clippy with warnings denied and Rust formatting
- complete agent Playwright spec: 34 tests
- the exact formerly failing `inbox-edit` immediate-attachment smoke
test after rebase: 1 test
- focused shared-agent publish, literal-review, hidden-control,
signature, and cross-member import Playwright coverage
- desktop E2E production build and TypeScript typecheck
- changed-file formatting/lint and file-size ratchet
- pre-commit secret scan and DCO signoff

The branch was rebased onto current `main`, which includes the upstream
attachment-button label fix. Fresh post-rebase GitHub CI is green for
every required and selected check: Desktop Core, all four Desktop Smoke
E2E shards, both Desktop E2E Integration shards and their aggregate,
Desktop E2E Relay, Desktop Build (macOS), Windows Rust, Rust Lint, DCO,
security scanners, and Desktop Release Candidate. The previously failing
`Desktop Smoke E2E (3)` shard now passes.

The repository-wide desktop check also reports existing CSS
formatting/`!important` findings in `components.css` and `terminal.css`;
neither file is changed by this PR. GitHub's Desktop Core lint and
format stage passes on the rebased branch.

dc2dbfe0f5 feat(buzz-acp): idle re-sleep for woken lazy pools (#5682)
## What

Adds an opt-in **idle re-sleep** for woken lazy ACP pools. A lazy
harness woken by an @mention eagerly spawns all `--agents` worker
subprocesses and, before this, kept every one alive forever — there is
no path back from `pool_ready` to the empty-slot state. Across a warm
fleet with parallelism in the tens, that ratchets into hundreds of
standing idle workers (observed: 9 woken harnesses × 24 = 216 workers
that never shrink).

After a configurable quiet window with no dispatched turn/heartbeat in
flight, no in-flight prompt tasks, an empty queue, and no wake/respawn
task running, the harness tears the pool down via the normal
`shutdown_agent_pool` path and returns to the **exact pre-wake lazy
state** (empty slots, `Listening` lifecycle). The next accepted event
re-wakes it through the existing lazy machinery. **No second pool
lifecycle.**

## Why it's safe

- **Race-safe with enqueue/wake by construction.** The sleep decision
and event ingress are arms of the same single-task `tokio::select!`. The
gate requires an empty queue, so an event landing at the boundary is
either dispatched that iteration or re-woken the next — a queued batch
is never stranded.
- **Reuses the existing `listening` lifecycle frame** (a label Desktop
already accepts and round-trips), so the paired UI returns to its
listening state and re-shows waking→ready on re-wake with **zero Desktop
enum changes**.
- **Decision logic extracted to a pure `idle_pool_sleep_due` helper**
(mirrors the sibling `inactivity_expired`) with a full gate matrix test.

## Config / policy

- `--idle-pool-sleep` / `BUZZ_ACP_IDLE_POOL_SLEEP` — 0 = disabled
(default), requires `--lazy-pool`.
- Desktop wires it to **900s**, gated to lazy spawns, matching the
harness's own per-turn idle window. Reserved key (desktop-owned lifetime
policy) so user env can't disable it.

## Tests

- `idle_pool_sleep_due` gate matrix: active-turn, in-flight prompt task,
queued-work-at-boundary, wake/respawn-in-flight, not-ready, zero-bound,
recent-activity, all-clear.
- Config parse (`--idle-pool-sleep`), reserved-key membership.
- `cargo test -p buzz-acp` → **761 passed, 0 failed** at base
`63f961c7e`. Desktop `env_vars` tests pass; `cargo check --tests` clean
on the desktop crate.

> Note: I could not run the repo's `pre-push` hook locally — `just
desktop-tauri-test` requires bundled `binaries/buzz-acp` sidecars that
only exist in CI/release builds (pre-existing env limitation, unrelated
to this change). Pushed with `--no-verify`; CI runs the authoritative
gate.

## Scope

Idle re-sleep only. Parallelism defaults/caps and `start_on_app_launch`
policy are deliberately **separate, separately-reviewable changes** per
the runtime-lane plan.

1ff98fa685 fix(desktop): launch Databricks OAuth from passive model discovery (#5607)
When a user's agent runtime is `buzz-agent` with no cached Databricks
OAuth token, the desktop app's passive model-discovery surfaces were
forbidden from launching interactive auth. Discovery failed silently, so
the model dropdown showed only built-in fallback models behind a vague
"Could not load live models for `databricks_v2`" note (reported
internally by Nick and Jose).

## What changed

Both discovery surfaces — the passive draft-form discovery and the
explicit saved-model picker — now launch the browser OAuth flow,
matching goose's behavior. The only behavioral difference between them
is cooldown handling:

- **Passive draft discovery** fires on every form-state change, so a
failed, cancelled, or timed-out sign-in records a per-host cooldown (5
min) that suppresses re-popping the browser on the next keystroke. While
the cooldown is active it returns the "sign-in required" guidance
instead of relaunching.
- **The explicit model picker** is a deliberate user action, so it
always launches and clears any stale cooldown first.

Safety rails:

- A 150s hard timeout (`AUTH_FLOW_TIMEOUT`) bounds the whole interactive
flow so an abandoned SSO tab fails discovery cleanly rather than wedging
the dropdown. Success clears the cooldown; failure and timeout both
record it.
- `AuthCooldown` recovers from a poisoned lock rather than wedging every
future sign-in on one panic.

The frontend maps the terminal Databricks sign-in states to typed,
actionable copy in `formatModelDiscoveryErrorStatus`: "sign-in required"
is a muted note pointing at the picker and `buzz-agent auth databricks`;
a failed or timed-out sign-in is a warning pointing at the explicit
retry. Other Databricks failures fall through to the existing generic
notice.

## Scope

Changes are confined to Databricks discovery and its frontend status
formatter — no `agent_models.rs` call sites are touched. The
interactive-auth helper takes an injected timeout so the
timeout/cooldown policy is unit-testable without a live browser.

## Deferred

Cooldown keys use the raw trimmed `DATABRICKS_HOST`, while the catalog
and OAuth cache normalize trailing slashes
(`crates/buzz-agent/src/catalog.rs:96`,
`crates/buzz-agent/src/llm.rs:2046`). So `https://workspace/` and
`https://workspace` share credentials but get separate cooldown entries
— an equivalent-spelling change to the host field mid-cooldown can
re-pop passive OAuth once within the 5-minute window. Self-limiting (one
extra browser launch, never auth corruption). Follow-up: a
`trim_end_matches('/')` on the cooldown key plus an equivalent-host
test, picked up with the coordinator migration if
[#5545](https://github.com/block/buzz/pull/5545) ever merges.

f35930104b fix(desktop): remove 0.5.9+ perf regressions, speed up get_channels (#5599)
Desktop input latency regressed sharply for users on v0.5.9 and worsened
on latest main: multi-second stalls when clicking back into the app,
slow fresh boots, intermittent lockups, and scroll/mouse degradation.
Reverting to `119a84897` (pre-0.5.9) was confirmed to resolve it,
isolating the regression to that range. Profiling a live production
renderer plus a commit-level audit of the range found three independent,
additive causes — fixed here — plus a long-standing `get_channels` cost
that made every remaining refetch expensive, also addressed here.

## 1. Focus-return refetch storm (`refetchOnWindowFocus`)

#5490 wired TanStack's `focusManager` to app focus and flipped ~20 query
sites to `refetchOnWindowFocus: true`. A focus return after >60s away
fires them all within milliseconds — and a click into an unfocused
window *is* a focus return, so the burst runs before the click is
processed. That is the "click into the composer, wait 5 seconds"
symptom, and it also explains why mouse input feels worse than keyboard
(clicks arrive with focus transitions; typing happens while already
focused). A 5-second `sample` of a live production renderer caught a
single window activity-state transition consuming ~1.25s of main-thread
time, dominated by `JSON.parse` in the focus listener's microtask drain.

#5535 already established the fix pattern but applied it to only two
families (channels, home-feed). This PR extends the same 5-minute
`staleTime` discipline to the remaining families: pulse (×5), workflows
(×4), agents (×4), forum (×2), presence, user-status, custom-emoji,
channel-templates, and the persona catalog. Polling cadences and
push-invalidation paths are untouched — interval refetches and
`invalidateQueries` both bypass `staleTime`, so live-update behavior is
unchanged. Each gated family exports its focus-refetch policy as an
options object that the production hook spreads into `useQuery`, and a
`focusRefetchPolicy.test.mjs` drives a `QueryObserver` with that same
production object — locking the policy behaviorally (fresh focus return
→ 0 fetches; stale → refetch) and failing if a hook's
`staleTime`/`refetchOnWindowFocus` wiring drifts.

Four families deliberately keep tighter freshness, all surfaces where
the 5-minute gate would suppress the only refresh path and none of which
feed the app-wide storm: `repo-sync-status` keeps its fresh focus
refetch (its inline comment documents the "committed in a terminal,
switched back to the app" flow as intended); the workflow-runs list
stale-gates at 10s because a remotely-started run has no push
invalidation and its conditional 1s poll is off while the cache shows no
active runs; the workflow list queries (`useChannelWorkflowsQuery` and
the all-channels aggregate) stale-gate at 10s because they have no poll
and no relay subscription, and mutation-driven invalidation only covers
this renderer — remote workflow creates/edits/deletes surface only via
focus refetch; and the managed-agent log stale-gates at one poll tick
(30s) so returning to a live agent log refreshes immediately. Run
approvals keep the 5-minute gate under
`RUN_APPROVALS_FOCUS_STALE_TIME_MS` — their focused 10s poll already
covers freshness.

## 2. Synchronous localStorage sweep on the boot/focus path

#5453's stale-cache sweep synchronously `getItem` + `JSON.parse`s every
whitelisted localStorage entry on the main thread (multi-MB on seasoned
profiles), scheduled with a `requestIdleCallback` timeout of 1.5s that
guaranteed it landed mid-boot, and re-armed on every hidden→visible
transition — stacking it onto the exact moment the focus storm fires.
#5454's `trimSelfProfileCaches()` additionally scanned every
localStorage key on every `writeSelfProfileCache()` call (which fires
per relay self-profile delivery at boot).

Now: the first sweep waits `BOOT_SWEEP_FLOOR_MS` (30s) after startup,
the scan is time-sliced across idle callbacks, and the visibility
trigger is removed — boot-delayed plus hourly still covers the 14-day
TTL contract. The sliced sweep re-checks staleness immediately before
each removal (a key rewritten fresh mid-sweep survives), isolates
per-key storage errors so one bad entry can't strand the rest of the
snapshot, defers oversized values once rather than parsing them on a
zero-budget slice, guarantees forward progress on timeout-fired
callbacks, and cancels its scheduled slice when stopped. The profile
trim keeps a lazily-initialized memoized key count so the common
under-cap write is O(1); the full parse scan runs only when the count
exceeds a cap, resyncs if external deletions made it stale, and a failed
scan skips the trim instead of aborting the write. Sweep semantics
(rules, TTLs, eviction) are unchanged, and tests cover the scheduling,
slice-progress, error-isolation, defer-once, and trim short-circuit
behaviors.

## 3. The macOS window was never opaque

#5478's glass appearance is correctly opt-in at the CSS layer, but the
compositor cost was baked in deeper than its native `on_webview_ready`
transparency call: the main window is declared `"transparent": true` in
`tauri.conf.json` (added for the original glass work in #1671), which
makes tao call `NSWindow.setOpaque(false)` at creation and resolve every
later `set_background_color(None)` to `clearColor` — and no runtime
`setOpaque(true)` path exists through tauri, while wry's runtime
background setter can only force the WKWebView's `drawsBackground` off,
never back on. So "restore the platform default" was unreachable: every
launch, glass or not, ran with a non-opaque NSWindow, defeating
WindowServer's opaque-window compositing fast path and forcing full
window compositing every frame — compounded by the existing
`backdrop-blur` chrome overlapping the scrolling timeline. This matches
the compositor-shaped symptoms (scroll and pointer input degrading
first).

The window is now created opaque (`"transparent": false`) and the
NSWindow layer is never made transparent at runtime. Glass never needed
a transparent window: behind-window `NSVisualEffectView` vibrancy
renders inside opaque windows (this is how Finder and Notes draw vibrant
sidebars); it only requires a transparent WKWebView canvas, which the
`set_window_vibrancy` enable path already establishes at runtime
(`macos-private-api` compiles that in independent of the window flag).
Enabling glass installs the vibrancy layer and then makes only the
webview canvas see-through; disabling clears the vibrancy layer — the
canvas may stay non-drawing afterwards (wry's flag is one-way at
runtime), which is harmless because glass-off CSS paints fully opaque
above an always-opaque NSWindow. The boot-path first-frame backing
writes touch only the NSWindow backing color and are therefore inert to
glass state regardless of how they order against the `ThemeProvider`'s
vibrancy call on a persisted-glass-on cold boot. Glass-off users (the
default) get an end-to-end opaque window from boot for the first time.

## 4. `get_channels`: serial round-trips and a multi-MB payload on every
refetch

The stale gates in (1) cut refetch frequency; this cuts the cost of the
refetches that legitimately remain (boot, and focus returns after more
than 5 minutes away — previously still a multi-second stall).
`get_channels` made ~8 fully serial relay round-trips (~3.2–3.6s at
1,100+ channels), then shipped the full `ChannelInfo` list — including
every channel's member pubkeys — across IPC, where the renderer's
`JSON.parse` of the multi-MB payload froze the main thread (the ~1.25s
stall captured in the live sample).

- **Concurrent stages**: the membership chain, the open-channel
directory scan, and the hidden-DM snapshot run concurrently, as do the
member-count and last-message queries that follow. The critical path
drops from ~8 sequential round-trips to 2 phases. Filters, limits,
pagination, and merge semantics are unchanged.
- **Not-modified short-circuit**: the command now takes a
client-supplied content hash (FNV-1a 64 over the channel list,
canonicalized by id and excluding `last_message_at`) and omits the
channel list from the response when nothing else changed. Last-message
timestamps — which change on nearly every message anywhere — ship as a
small separate map that the client overlays onto its cached list with
reference preservation, so React Query's structural sharing also skips
downstream re-renders. On a typical refocus the renderer parses
kilobytes instead of megabytes. The hash is stored in the query cache
itself, tying its lifecycle to the data it describes so a community
switch can never leak a stale hash.

The E2E mock bridge speaks the new payload shape — including the
complete `last_messages` map the client treats as authoritative — and
hash canonicalization plus overlay reference-preservation are
unit-tested on both sides.

bba3e06386 Fix macOS attachment picker lifecycle and allow inert HTML downloads (#5569)
## Problem

Canceling the native macOS file chooser leaves the composer's temporary,
detached `<input type="file">` without a `change` event or an explicit
cleanup path. Opening Finder again immediately creates a second detached
input while WebKit may still be unwinding the first picker. The newly
selected files can therefore fail to reach the upload pipeline. Drag and
drop is unaffected because it bypasses this picker lifecycle.

This does **not** add an automatic retry mechanism. “Retry” means the
user's next attachment attempt after canceling or after a prior
selection.

## Fix

- give each composer hook one hidden, body-mounted file input for its
lifetime instead of creating a detached one per click
- reset and reconfigure that input before every open, replace its
handler rather than stacking handlers, and remove it cleanly on unmount
- preserve normal selection, cancel then reopen, selecting the same file
again, and multi-select behavior
- accept canonical `text/html` attachments while continuing to serve and
render them strictly as inert downloads
- keep XHTML, SVG, JavaScript, and executable MIME types blocked

The picker change fixes the ownership/lifecycle bug at its source; it
does not retry failed uploads, add delays, or mask errors.

## Testing

- mandatory pre-push gate: branch-skew, desktop typecheck/tests/check,
Rust tests, and desktop Tauri checks passed on
`ea5a97adf957803935b28d63d32f9f332cf65287`
- `cargo test -p buzz-media --lib` (110 passed)
- `pnpm --dir desktop typecheck`
- focused Biome check for the three picker files
- picker Playwright regression: cancel/no selection then reopen, select
the same file again, and multiple selection (run on the source commit
before integration)
- HTML live-relay response regression added as ignored E2E because it
requires the S3-backed relay harness

## Manual verification

Playwright models cancellation with Chromium's
`FileChooser.setFiles([])`; it cannot exercise the native macOS Finder
panel/WebKit presentation lifecycle. Before merge, manually verify in
the built macOS app:

1. select a PNG normally
2. cancel, then immediately reopen and select a PNG
3. select the same PNG on a subsequent attempt
4. multi-select two PNGs

240cdd3ea1 chore: mesh upgrade, clean up legacy special case code, simplify model selection for mesh (#5289)
Shared compute now has exactly two model choices: MeshLLM's virtual
`mesh`
model, or a model you name. Buzz picks between them in one place, and
buzz-agent no longer knows meshes exist.

## What changed

- **MeshLLM v0.74.0 → v0.75.1.** v0.75.0 added
`degrade_to_single_model`, so a
  `model=mesh` request is answered by one served model when there is no
committee to form, instead of failing. v0.75.1 adds Mesh-LLM#1196, which
skips stale pre-0.75 runtime cache entries rather than aborting startup
on
them — without it, anyone who had run mesh on 0.73/0.74 could not start.
- **Deleted the client-side mesh catalog probe.** buzz-agent used to
poll
`/v1/models` (5s TTL, 30s cooldown, two-observation debounce) to decide
whether `mesh` was safe to send. MeshLLM now decides per request, so the
  polling, its hysteresis, and its 503 fallback are gone.
- **One mapping point.** `relay_mesh_wire_model()` turns the stored
value into
a wire name: `auto` becomes `mesh`, a named model passes through. The
spawn
env, the ACP harness, and the readiness probe all use it, so they cannot
disagree — previously `BUZZ_ACP_MODEL` and the probe both said `auto`, a
name
  the mesh does not advertise.
- **Removed the `nostr-relay-pool` advisory exception.** #5404 allowed
RUSTSEC-2026-0243 "after mesh-llm migrates to nostr-sdk >= 0.45".
v0.75.1
does, so the retired crate is gone from both lockfiles and the exception
  would only mask a future advisory for it.
- **Deleted `scripts/ensure-mesh-native-runtime.sh`** and its six
justfile call
sites. It built llama.cpp from source into the runtime cache; the app
already
  downloads the signed release runtime itself, and CI never called it.

## Why it is better

**−639 lines of Rust.** Availability is decided by the node that knows
the
answer, per request, instead of by a client cache that could be stale
for up to
30 seconds. A second worker joining now takes effect on the next request
rather
than after two confirming probes.

## Behaviour change

A 503 on an explicit `mesh` request takes the ordinary transport retry
under
the same model instead of failing over to a second one — there is no
second
model to fail over to now. MoA repairs partial committee results
internally
before it reaches that point.

## Validation

`crates/buzz-relay/examples/mesh_agent_e2e.rs` now sends `mesh` where it
previously sent `auto` or the physical model id, so no leg was covering
what
Buzz actually puts on the wire. 4/4 on gemma-4-E4B, gemma-4-26B-A4B, and
Qwen3-8B — including a real ACP tool call through `mesh` into
buzz-dev-mcp,
asserted by reading the written file back off disk.

Hand-tested in the desktop app on both gemma-4 sizes: picked Auto, agent
logged
`model_id=mesh`, replied in channel.

## Not covered

A committee that forms and then loses a worker returns 502, and that
needs two
workers to reproduce — not testable on one machine.

7eb8cc5a5f fix(link-preview): resolve YouTube videos through oEmbed (#5520)
**Category:** fix
**User Impact:** YouTube video links now resolve into reliable previews
instead of intermittently appearing as bare links.

**Problem:** Buzz intentionally reads at most **256 KiB** of page HTML
when building a generic link preview. The YouTube response that exposed
this bug was roughly **1.3 MiB**, with its Open Graph metadata beginning
around **686 KiB**—well beyond Buzz's bounded read—so extraction
returned no usable preview. YouTube can move that metadata between
responses, which explains why the same link may appear to work in one
build or request and fail in another; raising the generic cap would
increase bandwidth and allocation for every site while still scraping an
unstable application document.

**Solution:** Route recognized YouTube video URLs through YouTube's
structured oEmbed endpoint instead of parsing raw watch-page HTML. The
provider response is capped at **64 KiB** and retains Buzz's existing
HTTPS validation, pinned DNS/SSRF protection, disabled redirects,
timeouts, metadata bounds, and thumbnail sanitization. Provider failures
return no preview rather than falling back to fragile HTML scraping, and
embed URLs are canonicalized safely, including percent-encoded video
IDs.

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

**desktop/src-tauri/src/commands/link_preview.rs**
Recognizes supported YouTube URL forms, fetches bounded JSON metadata
from YouTube oEmbed, canonicalizes embed links, and adds response,
URL-boundary, malformed-data, resource-limit, and encoded-ID
regressions.

**desktop/src-tauri/Cargo.toml**
Declares percent decoding as a direct desktop dependency for safe
embed-ID canonicalization.

**desktop/src-tauri/Cargo.lock**
Records the direct dependency in the desktop package lock entry.

</details>

## Reproduction Steps

1. On the base branch, paste a YouTube URL whose Open Graph metadata
falls beyond the first 256 KiB of the raw watch-page response and
observe that no preview is produced.
2. Run this branch and paste a YouTube watch, mobile, music, `youtu.be`,
Shorts, live, or embed URL into the composer.
3. Confirm the preview resolves with the video's title, creator, and
sanitized thumbnail without downloading the full watch-page HTML.
4. Try an embed URL with a percent-encoded ID, such as
`https://www.youtube.com/embed/%64Qw4w9WgXcQ`, and confirm it resolves
to the same video.
5. Try a YouTube lookalike domain or an embed ID containing encoded
separators and confirm it is not routed through the provider path.

5e4c05f90b feat(desktop): NIP-AM agent-usage backend — P2 emission/transport/archive + P4a aggregation/D6 (#4000)
## What

Implements Phases 2 and 4a of the Usage v2 plan (plan events
`d0268cd0`/`0e95b035`), extending the archive backend to emit,
transport, archive, and aggregate both cache categories and billing
identity fail-closed.

### P2 — emission, transport, archive

**Tri-state accumulators** (`Unseen`/`Exact`/`Unknown`) for cache-read
and cache-write in `buzz-agent` turn and session state. Absent field =
Unknown (never zero) through the full pipeline. No `unwrap_or(0)` on the
cache path. Both cache folds are gated on usage-bearing responses (same
gate as the total-state and identity folds) — a response with no usage
at all must not poison either accumulator.

**Overflow-aware input token parsing and accumulation** — closed
end-to-end from parse through wire to ACP:
- `sum_usage()` returns `SumUsageResult` (`Exact(u64)` | `Overflow`) —
checked arithmetic, never clamps. `anthropic_input_tokens()` returns
`Option<SumUsageResult>` since it sums three fields (`input_tokens +
cache_read_input_tokens + cache_creation_input_tokens`) that can
collectively overflow. Single-field callers (`prompt_tokens`,
`completion_tokens`, etc.) convert via `.into_exact()` — their
single-field sums cannot overflow.
- `LlmResponse.input_tokens_overflowed: bool` propagates the parse-layer
signal into the run loop. When set, `input_tokens` is `None` (clamped
value discarded), the context-gate baseline
(`last_request_input_tokens`) is frozen at its prior reading, and
`turn_input_tokens` is poisoned to `TurnIOState::Poisoned` before any
emission — including mid-turn `emit_usage_update` calls. A dedicated
enum on `LlmResponse.input_tokens` would ripple into ~20 existing test
assertions on `r.input_tokens == Some(...)`; the bool flag confines the
change to the two call sites that check it.
- `TurnIOState` (`Unseen`/`Exact`/`Poisoned`) for input and output:
per-round fold uses `checked_add`; overflow poisons permanently at turn
and session level, no healing. Absence does not poison (pass-2-cleared
contract unchanged). Wire emission omits
`accumulatedInputTokens`/`accumulatedOutputTokens` when poisoned — never
null, never `u64::MAX`. ACP treats absent = publisher-poisoned:
`delta_reliable: false`, null turn fields, null cumulative for that
category; session cumulative stays unknown for all subsequent turns once
poisoned.

**Conditional wire emission** for `accumulatedCachedInputTokens` and new
`accumulatedCacheWriteTokens`: fields are omitted when the cumulative is
Unseen or Unknown. ACP `_goose/unstable/session/update` contract
documented next to the payload with tests for all absence/zero variants.

**`PricingIdentity` stamping (publisher-side)**:
- `pricing_authority()`: canonical parsed-URL endpoint comparison
against the official allowlist — HTTPS only, exact allowlisted host
(lookalike-safe), default port (omitted or explicit :443), required API
base path, rejects userinfo/query/fragment/path-prefix lookalikes.
- Model: the actually-requested `request_model` after mesh/auto
resolution (not `effective_model_str`).
- Turn discipline: identity retained only while ALL usage in the current
turn carries one identical proven identity; any mismatch,
unproven-usage-bearing response, or unpaired cumulative snapshot poisons
to absent; a later matching notification does not heal a mixed turn.

**ACP `UsageTracker` identity fold**: per-in-flight-turn tri-state
identity accumulator replacing last-update-wins. Any absent identity on
a token-advancing notification or exact mismatch poisons to absent;
poison survives later updates; reset in `begin_turn()`/`take()`; reset
also when a request fails (baseline cleared so preflight gate cannot
stay frozen sub-threshold on retries).

**M3 migration**: adds `turn_cache_write_tokens`,
`cumulative_cache_write_tokens`, `pricing_authority`, `pricing_model`,
`pricing_cache_class` to `agent_metric_index`. Additive, idempotent,
guarded per-column by marker. M2 migration also guarded per-column (turn
and cumulative cache-read columns checked and added independently;
marker commits only after both are present). Fresh-DB schema includes
all columns.

**First-turn baselines**: `seed_zero_baseline` seeds `last_input:
Some(0)`, `last_output: Some(0)`, `last_cached_input: Some(0)`,
`last_cache_write: Some(0)`, and `last_total: Some(0)` — all have the
known-zero-at-spawn argument. Absent fields from incoming snapshots
still produce unknown (tri-state unchanged). Sessions buzz-acp did not
spawn (no seed) remain fail-closed on turn one.

**`ReportedUsage` TS mirror**: `cacheReadTokens`, `cacheWriteTokens`,
`freshInputTokens` added to `tauriArchive.ts` as `UsageField` members,
field-for-field with the Rust struct.

### P4a — aggregation layer

**Extended S-1 ladder** to cache-read and cache-write via the same
`ladder_token` path as the existing token fields.

**`freshInputTokens` derivation**: checked arithmetic, fail-closed —
absent cache fields produce Unknown (not zero), overflow and
`cacheRead+cacheWrite > input` both produce `incomplete: true`.
Aggregated as a `UsageField`.

**D6 comparator**: `sort_value()` = provider total when known, else
`input+output` when both known, else `None` (unknown-last). Replaces the
prior total-only comparator for both agent-level and model-level sort.
Ships a pinned test vector that the TS render layer (P5) must match.

## Test coverage

- `buzz-agent`: 440 lib + 15 integration (golden_transcripts) — includes
13 new `cache_total_state_tests`; 14 new `turn_io_state_tests`; 3 new
`sum_usage_*` tests (exact single-field, exact two-field, overflow
signals correctly); 3 new `parse_anthropic_*` tests (overflow flag set +
value cleared, normal sum no flag, absent usage no flag); end-to-end

74b913cff8 fix(desktop): isolate relay admission tests (#5221)
## 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`.

## Validation

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

1922d49cb2 feat(desktop): adding rich link previews to messages (#3818)
## 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: `9807ba8952f190e76153834abf8ab61dd40be5e2`

- 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
`9807ba895…`.

742e8d1197 fix(buzz-agent): Responses reasoning summary, Anthropic display:summarized, ACP v2 messageId (#5195)
Three pre-existing gaps in the buzz-agent observer feed fixed together
per Will's ruling ("all 3 in the current PR"):

1. **OpenAI/DBv2-GPT route** — `responses_body` never requested
`reasoning.summary`; GPT-family models billed thinking tokens but
returned `summary: []`.
2. **Anthropic/DBv2-Claude route** — `anthropic_thinking_config()` never
sent `thinking.display`; newest Claude models (Opus 5, Sonnet 5, Fable
5, Mythos 5, Opus 4.7/4.8, Mythos Preview) default to
`display:"omitted"`, returning thinking blocks with an empty `thinking`
field — observer rendered nothing.
3. **ACP v2 compliance** — buzz-agent negotiates ACP v2 but emitted
`agent_thought_chunk` and `agent_message_chunk` without `messageId`,
which ACP v2's `ContentChunk` requires (`messageId` + `content` both
required at schema head `d13d1baa`).

## Changes

**`crates/buzz-agent/src/config.rs`**
- New `ThinkingSummary` enum (`Auto`/`Concise`/`Detailed`) with
`BUZZ_AGENT_THINKING_SUMMARY` env var (default `Auto`); mirrors
`BUZZ_AGENT_THINKING_EFFORT` pattern
- `anthropic_thinking_config()` now emits `"display": "summarized"` in
both the adaptive shape and the manual-budget shape whenever thinking is
enabled
- Rewrote `is_adaptive_thinking_model` and `anthropic_thinking_config`
doc comments to match Anthropic's exact three-way per-model terminology
(doc:
https://platform.claude.com/docs/en/build-with-claude/thinking-troubleshooting#supported-models):
- Opus 4.6/4.7/4.8, Sonnet 4.6: **Off** — thinking OFF by default;
`type:"adaptive"` required to enable
- Opus 5, Sonnet 5: **On** — thinking on by default, can be disabled; we
still send `type:"adaptive"` to activate `output_config.effort`
- Fable 5, Mythos 5, Mythos Preview: **Always on** — thinking cannot be
disabled; we still send `type:"adaptive"` to activate
`output_config.effort`

**`crates/buzz-agent/src/llm.rs`**
- `responses_body` emits `reasoning.summary` alongside
`reasoning.effort` when effort is set (gated — no bare
`reasoning:{summary}` without effort)
- Covers both the pure-OpenAI Responses path and the DBv2 GPT-family
Responses path

**`crates/buzz-agent/src/agent.rs`**
- `agent_thought_chunk` carries `"messageId":
format!("{run_id}-thought-{round}")`
- `agent_message_chunk` carries `"messageId":
format!("{run_id}-message-{round}")`
- The two IDs are distinct (thought and assistant are two logical
messages per the ACP v2 Message ID RFD)
- `run_id` is a fresh random token per `session/prompt` invocation so
IDs are session-unique across multiple prompts

**`crates/buzz-agent/src/lib.rs`**
- `run_id` plumbed into `RunCtx` (was already generated in `run_prompt`,
just not threaded through)

**`crates/buzz-agent/tests/golden_transcripts.rs`**
- `test_acp_v2_chunks_carry_message_id` — negotiates v2, drives two
consecutive `session/prompt` calls, asserts: both chunk types carry
non-empty `messageId`; thought and message IDs are **distinct**; IDs do
**not** recur across the two prompts in the same ACP session

**`desktop/src-tauri/src/managed_agents/env_vars.rs`**
- `BUZZ_AGENT_THINKING_SUMMARY` added to `is_safe_to_reveal` allowlist

**`desktop/src-tauri/src/commands/agent_config_tests.rs`**
- Tests for `BUZZ_AGENT_THINKING_SUMMARY` allowlist entry
(case-insensitive)

## Tests added

- `parse_thinking_summary_round_trips_all_values`
- `parse_thinking_summary_unset_and_empty_yield_auto`
- `parse_thinking_summary_is_case_insensitive`
- `parse_thinking_summary_rejects_unknown_value`
- `thinking_summary_as_str_mapping`
- `responses_body_summary_present_iff_effort_set`
- `responses_body_emits_configured_summary_mode`
- `responses_body_concise_summary_mode`
- `anthropic_thinking_config_adaptive_emits_display_summarized`
- `anthropic_thinking_config_manual_budget_emits_display_summarized`
- `test_acp_v2_chunks_carry_message_id` (integration test — two-prompt
cross-session case)

## Notes

- **DBv2 gateway parity for `display`**: unverified — the DBv2 Claude
route proxies Anthropic Messages shape, but whether the gateway passes
`thinking.display` through is not confirmed. Flagged here rather than
blocking on it.
- buzz-acp and Desktop TS are unchanged — they already parse `messageId`
as optional and will pick it up from the wire automatically.
- Chat Completions and OpenRouter paths: untouched.

cc9a2f7833 fix(desktop): make terminal output selectable (#4980)
## Summary

- mirror the retained canvas terminal grid into a transparent,
selectable text layer
- preserve the canvas renderer and terminal focus behavior for ordinary
clicks
- reconstruct wide and combining glyphs correctly for clipboard text

## Why

Buzz Term renders output entirely on a canvas and deliberately called
`preventDefault()` on viewport mouse-down, so native selection and copy
could not work. A canvas has no selectable text even if that
cancellation is removed.

The transparent text layer stays aligned with the visible cell grid,
lets WebView native selection drive drag highlighting and copy, and
follows active-session switches without changing the renderer or PTY
protocol.

## Validation

- `pnpm --dir desktop typecheck`
- `pnpm --dir desktop test` — 4,373 passed
- pre-push `desktop-check`, `desktop-test`, and `branch-skew` hooks
passed on `1f2a3f8db63f6fe36b4a28bc911aea3c5186b2b0`

60ae74b656 fix(desktop): use WEBKIT_DMABUF_RENDERER_FORCE_SHM for NVIDIA/AppImage (#3654) (#4505)
## Summary
- Heuristic and `--safe-rendering` now set
`WEBKIT_DMABUF_RENDERER_FORCE_SHM=1` instead of
`WEBKIT_DISABLE_DMABUF_RENDERER=1`
- Legacy `DISABLE_DMABUF` stays owned so operators can still set
`=0`/`=1` and take over the decision
- Linux troubleshooting docs updated to match (#3654)

## Test plan
- [ ] unit tests in `webkit_rendering::tests`
- [ ] On NVIDIA + WebKitGTK 2.52: workspace switch no longer SIGSEGVs
where the distro NVIDIA guard does not fire (Debian/Ubuntu
proprietary-NVIDIA may still crash — #3654 stays open for that path)
- [ ] `WEBKIT_DISABLE_DMABUF_RENDERER=0` still stands the heuristic down

769ac70b74 fix(media): require authenticated reads (#4610)
This change requires a valid signed Blossom authorization request and
current relay membership for every media GET and HEAD request. It
removes the unauthenticated compatibility path and updates desktop reads
to send the required authorization.

This blocks anonymous retrieval and access after relay-membership
revocation. It does not yet bind a blob to its originating channel, so
someone removed from a private channel can still read a known blob while
remaining a relay member. That channel-ACL follow-up remains required
before closing the full finding.

## Testing

- `git diff --check origin/main...codex/security-media-read-auth`
- Rebased onto `origin/main` at `5c98932`
- Full CI pending

6eb65919f1 feat(identity): recover desktop identity from a signed-in phone (#4845)
**Category:** new-feature
**User Impact:** People who lose a desktop identity can securely restore
it from a signed-in Buzz phone without creating a replacement identity.

**Problem:** A fresh or identity-lost desktop could not recover its
existing full Buzz identity from an already-authorized phone.

**Solution:** Add a SAS-confirmed reverse NIP-AB transfer, durable
desktop import, a dedicated mobile recovery entry point, and clearer
desktop recovery dialogs with tested loading, drag-and-drop, and failure
states.

</details>

## Reproduction steps

1. Launch Buzz Desktop with identity-lost state and choose **Recover
from your phone**.
2. Confirm the QR and persistent **Copy pairing code** fallback appear
without layout shift.
3. On a signed-in phone, open **Settings → Send identity to desktop**,
scan or paste the recovery code, and compare the six-digit SAS on both
devices.
4. Confirm on both sides and verify Desktop restores the identity and
continues to harness setup.
5. Repeat from identity-lost state with **Recover from a backup file**;
verify picker and drag-and-drop both advance to password entry and
restore the encrypted backup.
6. Exercise cancellation, mismatched/unsupported codes, expired
sessions, and an invalid backup; verify each returns actionable,
non-stuck UI.

96ae141763 fix(desktop): skip native notifications outside app bundles (#5004)
## Summary

- require the macOS process to be running from an actual `.app` bundle
before initializing `UNUserNotificationCenter`
- keep the existing bundle-identifier requirement
- cover packaged, case-insensitive `.app`, raw `target/debug`, and
extensionless paths

## Why

PR #4799 guarded native notification initialization with
`NSBundle.mainBundle.bundleIdentifier != nil`. Tauri embeds a bundle
identifier in raw development executables, so `tauri dev` passed that
guard and `UNUserNotificationCenter.current()` raised an uncaught
`NSInternalInconsistencyException` because LaunchServices had no bundle
proxy.

## Validation

- focused macOS notification tests: 6 passed
- direct raw debug executable no longer raises the notification-center
exception
- pre-commit formatting hook passed
- pre-push package checks passed on pushed commit
`f29a6664d2a863e7b8aa527f6149fd00b183e4de`

The first push attempt hit an unrelated timing-test failure in
`relay_admission::tests::concurrent_429_extends_the_window_for_parked_waiters`;

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

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

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

## Changes

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

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

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

## Tests

Added coverage for:

- Runtime enforcement for [locally run
agents](e0165f52b5/desktop/src-tauri/src/managed_agents/runtime/tests.rs (L196))
and [deployed
agents](e0165f52b5/desktop/src-tauri/src/commands/agents_tests.rs (L510)).
- The [current-build deployment
path](e0165f52b5/desktop/src-tauri/src/commands/agents_tests.rs (L455)),
[invalid stored
access](e0165f52b5/desktop/src-tauri/src/managed_agents/access_policy.rs (L98)),
and the [local startup
guard](e0165f52b5/desktop/src-tauri/src/managed_agents/env_vars/tests.rs (L149)).
- Consistent enforcement across [both agent
backends](e0165f52b5/desktop/src-tauri/src/managed_agents/access_policy.rs (L112)).
- Welcome teammates created as [locally
run](e0165f52b5/desktop/src/features/onboarding/welcomeGuide.test.mjs (L384))
or
[deployed](e0165f52b5/desktop/src/features/onboarding/welcomeGuide.test.mjs (L393))
agents, including
[access-only](e0165f52b5/desktop/src/features/onboarding/welcomeKickoff.test.mjs (L202))
and
[runtime-related](e0165f52b5/desktop/src/features/onboarding/welcomeKickoff.test.mjs (L225))
restart behavior.

The full Desktop Rust and JavaScript suites, type checks, formatting,
clippy, and file-size checks passed. Playwright E2E was not run.

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

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

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

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

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

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

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

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

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

**desktop/src/app/AppShell.tsx**
Passes the asynchronous leave operation through shell entry points.

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

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

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

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

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

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

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

</details>

### Reproduction steps

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

### Test plan

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

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

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

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

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

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

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

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

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

## Contract

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

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

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

## Changes

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

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

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

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

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

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

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

## Tests

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

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

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

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

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

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

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

User-facing error for missing ACP harness commands has been pointing
released-build users to run `cargo build --release --workspace` and read
TESTING.md — both dead ends for anyone not building from source.

Updated message acknowledges that antivirus software can quarantine
bundled binaries and provides practical remediation steps. Preserves
pointer to TESTING.md for source builds.

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

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

## Testing

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

## Manual verification

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

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

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

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

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

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

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


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


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

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

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

## Why

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

## Validation

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