Salman MohammedandGitHub f64899e5d1 Remove Startup Recovery section in base prompt (#6161)
## Why

Managed channel sessions already receive authoritative per-turn context.
The old startup recovery checklist told every new session to scan the
global feed

## What

- Remove `Startup Recovery` with concise channel and heartbeat turn
contracts.

## Risk Assessment

Low. This changes prompt guidance and its test only; routing and runtime
behavior are unchanged.

54f11219ef fix(acp): gate relay-signed workflow messages on their attributed author (#6129)
## Problem

Scheduled workflow `send_message` actions fire and land in the channel
with correct `p` tags for the mentioned agents — but the agents never
wake. The wake-up is silently dropped.

**Root cause:** workflow messages are signed by the **relay keypair**
(`workflow_sink.rs` signs with `state.relay_keypair`), so `event.pubkey`
is the relay's pubkey, not the workflow owner. In `buzz-acp`, the
inbound author gate (`author_allowed`) runs **before** the `p`-tag
mention check. Under the default `respond_to = owner-only`, the relay
pubkey is neither the owner nor a sibling, so every workflow wake-up
dies at the gate with a debug-level `"inbound author gate — dropping
event"`.

The relay-side comment even says the mention `p` tags exist *"so
mentioned agents are woken (wake is p-tag gated)"* — but wake is also
author-gated, and that path was missed.

## Fix

Gate relay-signed workflow messages on their **attributed author** — the
pubkey that created the workflow — instead of the relay pubkey:

- **Relay:** `workflow_sink.rs` now emits an explicit
`buzz:workflow-owner` tag carrying `workflow.owner_pubkey` (the workflow
creator, which the executor already passes as `author_pubkey` and whose
channel access the relay verifies before emitting). Ownership is never
inferred from `p`-tag order; mention `p` tags play no role in
attribution.
- **Harness:** at startup, `buzz-acp` fetches the relay's NIP-11 `self`
pubkey (new `RestClient::fetch_relay_self`, public `/info` endpoint).
Best-effort: fetch failure just logs a warning and preserves pre-fix
behavior.
- **Gate:** an event that is (a) authored by the relay `self` key, (b)
tagged `buzz:workflow`, and (c) carries a well-formed
`buzz:workflow-owner` pubkey is gated on that owner, through the exact
same owner/sibling/allowlist policy as a direct author.

## Security notes (all fail closed)

- No NIP-11 `self` pubkey → no exemption.
- `buzz:workflow` / `buzz:workflow-owner` tags on a non-relay-signed
event → ignored (a member cannot forge the exemption; the relay verifies
signatures on submission and only the relay holds its key).
- Relay-signed event without the tags, or with a malformed owner value
(not 64-hex) → plain author gate.
- Who is @mentioned in the message has no bearing on whose authority is
evaluated.
- A workflow owned by a random channel member still cannot wake an
owner-only agent — the owner's pubkey must pass the same policy.

## Testing

- 7 unit tests (`workflow_attributed_author_tests`) covering
attribution, fail-closed paths, p-tag independence, malformed owner
values, and the forgery case.
- Extended the PG-gated `workflow_send_message_p_tags_mentioned_member`
integration test to assert the `buzz:workflow-owner` tag.
- `cargo test -p buzz-acp`: 785 passed, 0 failed. `cargo test -p
buzz-relay --lib workflow_sink`: 17 passed. Clippy + fmt clean. (9
pre-existing `buzz-relay` failures in unrelated
`api::media`/`api::admin` tests fail identically on the base commit
without this change.)

Found while debugging scheduled automations in a Buzz review-pipeline
channel: two cron workflows fired daily @mentions at agents that never
responded, while direct human @mentions woke them instantly.

5b3f0375a2 fix(acp): replace Goose native system prompt (#5964)
## Why

Buzz currently appends its managed prompt to Goose's native prompt, so
managed agents receive both instruction sets instead of the intended
Buzz-only system prompt.

## What

- Send Goose's custom session system-prompt request with `mode: "set"`
- Lock the replacement contract in the ACP request test

## Risk Assessment

Low — the change is limited to Goose session setup; adapters that do not
implement Goose's custom method keep the existing method-not-found
fallback behavior.

## References

Goose v1.46.0 routes `set` to `override_system_prompt`, and its prompt
builder selects that override instead of rendering the native
`system.md`: [ACP
handler](https://github.com/aaif-goose/goose/blob/98c11ce2ee7b9b302978aa64b1eab7d0895607c7/crates/goose/src/acp/server/manage_sessions.rs#L57-L93),
[prompt
builder](https://github.com/aaif-goose/goose/blob/98c11ce2ee7b9b302978aa64b1eab7d0895607c7/crates/goose/src/agents/prompt_manager.rs#L153-L191).

Validated end to end against the official Goose v1.46.0 binary with a
local OpenAI-compatible capture server: the provider request contained
the exact Buzz replacement prompt and did not contain Goose's native
base-prompt marker.

---

**Update Aug 15, 13:17 CDT:** Added the [Terra-high prompt-ablation
comparison](https://github.com/squareup/buzz-benchmarks/blob/4492f76349ccb638219f7d070735a4d2b679bc26/data/prompt-ablation/20260815-terra-high/comparison.md).

The Goose conditions used GPT 5.6 Terra at high effort on the same 11
Terminal-Bench 2.1 tasks, with two attempts per task and concurrency
four. The matched `append-full` and `set-full` runs used the same
persona and included the same Buzz platform prompt; Active-h is the
primary measure because it excludes Buzz lifecycle overhead.

| Goose condition | Pass | Active-h | Median active | Agent-h | Wall-h |
Tool calls |
|---|---:|---:|---:|---:|---:|---:|
| Native prompt + Buzz prompt (`append-full`) | 21/22 | 0.3042 | 0.85
min | 0.3974 | 0.1496 | 234 |
| Native prompt + persona only (`append-persona-only`) | 22/22 | 0.3050
| 0.75 min | 0.3990 | 0.1498 | 204 |
| Buzz prompt replaces native prompt (`set-full`) | 22/22 | 0.3340 |
0.87 min | 0.4296 | 0.1551 | 275 |

Replacing instead of appending produced one additional passing attempt,
but it was not an efficiency improvement in this small sample: versus
`append-full`, `set-full` increased Active-h by 9.8%, median active by
2.0%, Agent-h by 8.1%, Wall-h by 3.7%, and tool calls by 17.5%. It was
faster on only two of eleven per-task active-time medians
(`distribution-search` and `prove-plus-comm`). With two attempts per
task, these are directional results rather than confidence intervals;
they support this change as an instruction-isolation/correctness fix,
not a performance optimization, and argue against Goose's appended
native prompt being the main source of active-time cost.

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.

1d51081b8a Teach agents to inherit Buzz product intent (#5875)
## Summary

- make `VISION.md`, relevant `VISION_*.md`, and applicable testing
guides explicit planning and review inputs for non-trivial Buzz changes
- teach managed agents to load repository-root and path-local
`AGENTS.md` files after selecting a checkout
- distinguish CI evidence from exercising the live workflow for
user-visible and integration behavior
- turn repeatable mistakes into same-session durable lessons, keeping
only load-bearing rules in core memory and promoting shared lessons to
team guidance
- pin the new managed-agent prompt invariants in tests
- preserve the exact display name shown in Buzz when mentioning or
addressing someone; never infer or look up a surname merely to sound
more complete

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.

4749bc7be3 feat(acp): report standard adapter usage (#4950)
## Why
Claude Code and Codex expose standard ACP prompt-response usage, but
Buzz only consumed Goose’s private cumulative usage notification. Their
token use and Claude’s cumulative cost were therefore absent from NIP-AM
metrics.

## What
- Read per-turn `session/prompt` response usage for known Claude and
Codex adapters
- Publish Claude’s raw cumulative cost separately from per-turn tokens
without changing the NIP-AM schema
- Keep Goose usage exclusive and cover Claude/Codex wire serialization

## Risk Assessment
Low-to-medium: changes best-effort observability only and does not
affect prompt execution. The adapter-specific mappings preserve source
semantics and omit unavailable fields.

## References
- Validated with `cargo fmt --check`, `cargo test -p buzz-acp --no-run`,
and full `cargo test -p buzz-acp` (678 passed at `652e373a` before
merge-trailer amendment).

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.

6e0631f6b5 feat(acp): deliver channel description in prompt [Context] (#4552)
Channels carry a kind-39000 `about` description that the harness never
surfaced to agents. This delivers it in the per-turn `[Context]` block
so an agent knows what a channel is for without having to ask.

## What changes

- `relay::ChannelInfo` and `queue::PromptChannelInfo` gain a
`description: Option<String>` field.
- The `about` tag is parsed in both metadata paths: the startup
discovery map (`merge_discovered_channels`) and the lazy
`fetch_channel_info` lookup. Blank or whitespace-only values become
`None`.
- `format_context_hints` renders a `Description:` line under `Channel:`
for channel- and thread-scope turns. DM turns never render it.

## Safety

- The description is newline-collapsed to a single line before
rendering, so a multi-line `about` value can never spoof another
`[Context]` field.
- It is capped at 500 characters on a UTF-8 char boundary, with a `…`
truncation marker.
- Unresolved channel metadata renders no `Description:` line.

Session creation is untouched — the description rides the existing
per-turn `[Context]` block that already carries `Channel:`.

563e4346da Reduce repeated ACP session context (#5423)
## Summary

- deliver legacy ACP standing context once per live session, committing
delivery state only after a successful turn
- send only new thread/DM event deltas on later turns, with fail-open
behavior for missing IDs and failed/cancelled prompts
- fence native steer delivery acknowledgements by ACP session identity
so stale acks cannot poison replacement sessions
- keep context hints truthful when a fetch contains only the triggering
event versus history delivered earlier

## Validation

The pre-push hook passed on exact pushed head
`6a768f1bc80fe63c686acf8d730f177fff8add3c`:

- `branch-skew`
- `desktop-check`
- `desktop-typecheck`
- `desktop-test`
- `rust-tests`
- `desktop-tauri-checks`

Focused regression tests were also run while iterating:

- `channel_prompt_commits_delivery_state_only_after_acp_success`
- `in_flight_stale_native_steer_ack_cannot_update_replacement_session`
- thread/DM trigger-only versus previously-delivered context hint tests

## Known limitations and follow-ups

A local Goose smoke timed out at `session/new`. This diff does not
change code that executes at or before `session/new`; its earliest
affected runtime behavior is delivery-state insertion after session
creation succeeds. The smoke failure is therefore bounded as
environmental or pre-existing, but no successful live-provider turn was
obtained. Scripted ACP wire/lifecycle tests carry the regression
coverage.

- #5421 — distinguish post-delta, already-delivered, and fetch-truncated
context counts
- #5422 — define a standing-context re-delivery policy if a legacy
provider compacts it away

Durable process-restart/session resume remains out of scope for this
slice of #5342. #5386 also remains separate pending upstream adapter
support.

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
golden transcript drives real subprocess with Anthropic-shaped
`input_tokens: u64::MAX, cache_read: 1` response and asserts
`accumulatedInputTokens` absent from the emitted `usage_update` — no
logic duplication; 3 wire pin tests; 4 `fold_pricing_identity_*` tests;
`pricing_authority()` explicit-:443 acceptance
- `buzz-acp`: 700 tests (691 lib + 9 integration) — 4 new usage tests
(absent input → unreliable+null; absent output → unreliable+null;
goose-shaped both present unchanged; poison mid-session); 3 ACP behavior
tests; 7 pool lifecycle tests
- Desktop (Rust): 2259+ tests — 14 new P4a pinned tests; 2 M3 round-trip
tests; 1 serde key-shape test; 2 M2 partial-schema migration tests;
first-turn cache round-trip test

4da7264d90 fix(acp): pace observer telemetry at 1/s with per-channel batch envelopes (#4917)
## Problem

Observer telemetry is the noisiest client of the relay: the old pacer
(167ms spacing + 90/min rolling cap) let a busy session bill up to 6
events/second against the owner's message quota, and the rolling cap
silently *dropped* frames once exceeded.

Ruling from the rate-limiting investigation thread (channel
`826fc99b-1472-40e7-a529-6b9db8943b8c`): pace at 1/s, always emit,
minimal PR.

**Review round 1 (Max, Sami)** found the first cut wrong in three ways —
tick burst (all pending frames per tick), startup burst (`interval`
fires at t=0), and per-channel quota arithmetic. All fixed and
mutation-verified in round 1.

**Review round 2 (Sami, Max)** found two more against the round-1 head:
1. **Drain-rate collapse (Sami, blocker):** front-run-only packing meant
a frame held ONE event whenever channels interleaved — measured 275 B/s
vs 63.5 KB/s, so an ordinary 2-channel session fell minutes behind with
zero drops and no warning. Silent unbounded latency.
2. **Coalescer byte-cap bypass (Max):** chunks pending in
`ObserverChunkCoalescer` were unbounded and outside the 4 MiB cap — 500
distinct-`messageId` 50KB chunks retained ~48MB with `pending_bytes ==
0` and zero drops.

**Review round 3 (Max)** found the drop accounting undercounted merged
chunks: a coalescer entry that merged N same-`messageId` chunks counted
as **1** in `dropped_events` when evicted (50 merged 1KB chunks evicted
→ counter read 1, 49 generated events unaccounted). Fixed: accounting is
now denominated in **source (generated) observer events** end to end —
each pending entry tracks how many chunks it absorbed, eviction charges
that count, and the count survives flush into the publish FIFO.

**Review round 4 (Sami, Max)** found three more against the round-3
head:
1. **Coalescer byte undercount (both, independently):** a pending merged
entry retains its first chunk's text **twice** until flush — once inside
the serialized event skeleton and once in the extracted text accumulator
— but was charged only `serialized_len`, so true retention overshot the
4 MiB cap ~2× (measured 8.3 MB). Fixed: `push_pending` charges
`serialized_len(&event) + text.len()`.
2. **Cap regressions asserted the accumulator against itself,** which is
how the undercount hid. All three cap tests now assert on independently
**walked** retained bytes (`serialized_len` per FIFO entry +
`serialized_len + text.len()` per coalescer entry), with a secondary
`accumulator >= walked` sanity check. Reverting the fix makes them fail
at exactly 8,328,386 / 8,328,272 bytes.
3. **FIFO-arm source accounting was implemented but untested (Sami M13;
Max reproduced at `cc9333b7c` with 102/151):** the round-3 regression
only evicted a merged entry while still in the coalescer. New test
forces a merged entry (50×1KB, `source_events=50`) through flush into
the publish FIFO, then evicts it from there — mutating the FIFO eviction
to `dropped += 1` fails with the reviewers' exact numbers (102 vs 151).

**Review round 5 (Sami 9/9/9, Max 9/9/9)** — production judged
merge-safe by both; remaining items are tests only, all landed at
`63d821620`:
1. **The walker instrument was itself unverified (Sami M17–M20; Max
independently confirmed the `return 0` mutant survives):** every cap
test asks `walked_retained_bytes()` only for `<= CAP`, so a blinded
walker passes everything — and paired with a reverted `push_pending` fix
the two mutations cancel, hiding exactly the 8.3 MB overshoot it exists
to detect. New two-sided pin: the walker must SEE the first chunk's text
twice, and must agree with the accumulator EXACTLY while both stores are
non-empty. Kills M17, M18, M19, M20.
2. **Two pre-existing snapshot-clone siblings (Sami D5b/D5c;
byte-identical at merge-base `7334ad1e1` — not this PR's regression, but
the PR made the class visible):** aliasing the inner turns map leaks a
post-save turn into the snapshot; aliasing the inner tombstones map
leaks a post-save terminal that blocks a legitimate post-restore
resurrection. Two isolation tests with in-test controls — all three
inner-map clones in `saveActiveAgentTurnsForCommunity` are now pinned.

## Change

**Harness (`crates/buzz-acp`)**
- **Global pacer: AT MOST ONE relay frame per second**, regardless of
channel count or backlog size. `interval_at(now + 1s)` restores the
no-startup-burst property; `MissedTickBehavior::Skip` is now pinned by a
paused-time test (a stalled tick arm fires one catch-up frame, not one
per missed deadline). At 1 frame/s telemetry spends ≤60/min of the
shared 120/min quota; `OBSERVER_PUBLISH_TICK` documents the tradeoff as
the knob.
- **`ObserverPublishQueue` with gather-packing:** events wait as
byte-accounted events (FIFO). `next_frame()` packs the front event's
channel **gathered queue-wide in FIFO order** — frames never mix
channels, and each channel's events keep their FIFO order, but
cross-channel frame order MAY differ from arrival order. That is what
keeps the drain rate in **bytes per slot** (one ~64KB frame/s) instead
of front-run-length events per slot. **Null-channel events
(`agent_panic`-class) are packing barriers** nothing gathers across, so
causally-global events keep exact order against every channel.
- **One byte cap over BOTH stores:** the event FIFO and the coalescer's
pending chunk buffer count against the 4 MiB budget together; eviction
is oldest-first across both (queue front, then coalescer front —
structural age order) with accounting (warn + counter). A
high-cardinality chunk flood is bounded exactly like a plain event
flood. Coalescer entries are charged their **true** retention
(`serialized_len + text.len()` — the first chunk's text lives in both
the serialized skeleton and the extracted accumulator until flush).
- **Shutdown is not a burst bypass:** paced one-frame-per-tick drain
until empty.

**Desktop**
- `unwrapObserverBatch` expands envelopes on the live relay path and
archive-ingest seam (round 1, unchanged).
- **`activeAgentTurnsStore` watermark re-keyed per (agent, channel)**
with a dedicated null-channel bucket: the per-agent `(timestamp, seq)`
gate would silently skip a delayed channel's frames as stale under
gather-packing's intentional cross-channel reorder. Safe because every
turn-mutating path is channel-scoped by the event's own `channelId`
(endTurn's null-turnId fallback matches `turn.channelId`; resurrectTurn
keys on `event.channelId`), so per-channel serialization preserves each
guard the per-agent gate provided. The tombstone-cap justification is
rewritten for the new keying (worst case for an evicted tombstone is a
ghost badge the prune reaps — bounded cosmetic staleness, not
corruption). Community-switch save/restore deep-clones the nested map.
Other per-agent maps stay agent-keyed: the clock offset is a running
minimum (order-insensitive); turns/tombstones mutate only through
channel-scoped paths.

## Version skew — old desktop + new harness

Gather-packing *intentionally* emits cross-channel-reordered frames. An
**old desktop** (per-agent watermark) against a **new harness** will
silently skip a delayed channel's turn-state events as stale — working
badges on that channel can go stale/missing until its next fresh event.
Transcript and archive are unaffected (the transcript store sorts +
rebuilds on out-of-order arrival; the archive is per-channel by
construction). Ship desktop and harness together; skew degrades badges
only, not data at rest.

## Throughput ceiling — "lossless" is qualified

Sustained lossless rate is what fits in one ~64KB frame per second, now
genuinely in bytes under interleaving:

| event payload | events per frame | sustained ceiling |
|---|---|---|
| 100 B | 250 | 250 ev/s |
| 500 B | 99 | 99 ev/s |
| 2 KB | 30 | 30 ev/s |
| 10 KB | 6 | 6 ev/s |

With C channels producing concurrently, publish slots round-robin
between them: per-channel drain is ~64KB/C per second and the 4 MiB
burst budget (~64s single-channel) shortens accordingly. Beyond budget,
oldest-first drops **with accounting** — visible, designed loss.

**Accounting semantics:** `dropped_events` counts SOURCE (generated)
observer events, not retained entries — evicting a coalesced entry that
merged N chunks charges N. On the published side, a merged entry ships
all N sources' text in ONE event, so the reconciliation invariant is
`ingested == dropped_events + Σ source_events over published events`
(for unmerged events, source_events = 1).

## Verification

At `63d821620d3513505e8766ac691a8002f9d4a96f` (this head; `git rev-parse
HEAD` matched in the same shell as every run), rustc 1.95.0:
- `cargo test -p buzz-acp`: **689 lib + 9 integration, 0 failed** —
regressions: interleaved 2-channel drain packs into ≤4 frames not 200
slots; null-channel barrier; queue-wide gather with within-channel FIFO;
distinct-key 50KB chunk flood bounded by the cap with event-level
accounting (published + dropped == ingested, survivors newest);
paused-time `MissedTickBehavior::Skip` pin (verified to fail under
`Burst`: 3 frames vs 1); merged-key eviction accounts every absorbed
source chunk in BOTH arms — coalescer-side (Max's round-3 probe) and
post-flush FIFO-side (Sami M13 / Max's round-4 probe: fails 102 vs 151
under `+= 1`). All three cap tests assert on independently walked
retained bytes, not the accumulator (verified to fail without the
`+text.len()` fix: 8,328,386 / 8,328,272 vs 4 MiB); the walker itself is
pinned two-sided against the accumulator (all four blinding mutants
M17–M20 verified to fail it, including the walker+fix cancellation
pair).
- `cargo clippy -p buzz-acp --all-targets -- -D warnings` clean, `cargo
fmt --check` clean
- Desktop: `tsc --noEmit` clean; node tests **4366 passed, 0 failed** —
snapshot-clone family fully pinned: watermark aliasing (round 4), turns
aliasing and tombstone aliasing (round 5, pre-existing gaps; each mutant
verified to fail exactly its target test with an in-test control). Prior
rounds: cross-channel reorder processed, cross-channel-delayed
null-turnId `turn_error` evicts only its own channel's turn, null-bucket
replay idempotency, same-channel stale/duplicate still skipped,
watermark survives community-switch save/restore
- All pre-push hooks green at the pushed commit (branch-skew,
desktop-check, desktop-test, rust-tests, desktop-tauri-checks)

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

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

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

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

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

## Testing

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

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

## Operator notes

- `BUZZ_ACP_PERMISSION_MODE=bypassPermissions` no longer parses, so a
process configured with it fails to start rather than silently
downgrading.
- Desktop managed agents do not set a permission mode, so they inherit
`dontAsk`. The desktop has no permission prompt, so operations needing
approval now fail with no in-app way to approve them.

a1d78f2959 feat: Buzz entity links — rich preview cards + in-app navigation for repos, PRs, and issues (#4695)
## Summary

Gives Buzz-hosted git entities the same "GitHub-style" chat experience
GitHub links already get: rich preview cards, real titles, and
click-through — except clicks navigate **in-app** to the Projects view
instead of a browser.

- **Spec**: `docs/buzz-entity-links.md` — link scheme, slices, and
deferred work (`buzz://project`, OS deep links, web routes).
- **Canonical `buzz://` deep links**: new
`desktop/src/shared/lib/entityLink.ts` with builders + strict parser for
`buzz://pr?id=…&owner=…&d=…`, `buzz://issue?…`, and
`buzz://repo?owner=…&d=…`, mirrored by a Rust module
(`crates/buzz-cli/src/links.rs`) with a shared golden-format test so the
two implementations can't drift.
- **Preview cards**: `linkPreview.ts` recognizes `buzz://` entity links
*and* HTTPS relay clone URLs (`{origin}/git/<pubkey>/<repo>`, the shape
agents paste today). Both normalize onto the canonical `buzz://` href,
so the two spellings of a repo dedupe to one `Buzz`-provider card
(`BuzzMark` logo) rendered by `link-preview-attachment.tsx`.
- **Title enrichment**: PR/issue cards fetch the real subject from the
relay event (`subject` tag or first content line) via
`useResolvedLinkPreviews.ts`; the cache is community-scoped and reset in
`resetCommunityState()`.
- **In-app navigation**: clicking a card or inline anchor (including
HTTPS relay clone URLs whose origin matches the active relay) routes to
the canonical `30617:<owner>:<d>` coordinate via `goProject()`
(`markdown/entityLinks.tsx`). **Merge dependency: #4671 must merge
first** — route resolution for `30617:` coordinates is implemented on
that branch (`feat/multi-repository-projects`). Entity-link and
external-anchor logic were extracted out of `markdown.tsx` to stay under
the file-size ratchet.
- **Agent side**: `buzz pr open`, `buzz issues create`, and `buzz repos
create` now return a ready-made `link` field (omitted when the relay
returns `accepted: false`), and `base_prompt.md` instructs agents to
paste it verbatim when announcing work.

## Test plan

- [x] Desktop unit tests: pass, including new `entityLink.test.mjs` and
`linkPreview.test.mjs` coverage (golden formats, malformed-link
rejection, clone-URL/`buzz://` dedupe, origin-gated anchor behavior,
label-must-win invariant, cache epoch)
- [x] Rust: `cargo test -p buzz-cli` golden-format test +
accepted/rejected link guard assertions, clippy + fmt clean
- [x] Biome + `tsc --noEmit` clean; pre-push hooks
(desktop-tauri-checks, rust-tests, desktop-test) pass
- [ ] Manual: paste a relay clone URL and a `buzz://pr` link in a
channel — verify one card each, real PR title, and in-app navigation to
the Projects view

56003ebf98 docs(acp): explain per-channel session model in base prompt (#4729)
## Overview

Agents running in Buzz have no built-in awareness that each channel is
an isolated conversation context. When a human mentions work "you" are
doing in another channel, the current session can misread this as its
own active context and try to coordinate, re-plan, or take ownership of
it — causing confusion and wasted turns.

## What changed

Added a `## Session Model` section to
`crates/buzz-acp/src/base_prompt.md`, inserted immediately after the
opening paragraph and before `## Buzz CLI`. The section explains:

- Each channel is a separate session; multiple sessions of the same
agent identity may be active simultaneously.
- Sessions share core memory, workspace, and relay — but not
conversation context or in-flight reasoning.
- Cross-channel work belongs to the owning session by default; the
current session may take it over only when the human explicitly requests
it.

No runtime code changes. Base prompt only.

7ff5fc3189 feat(acp): deliver system prompt via _meta.systemPrompt for claude-agent-acp (#4395)
`claude-agent-acp` (since v0.6.0 / PR #91) accepts `_meta.systemPrompt:
{append: text}` on `session/new` to append to the adapter's native
preset while keeping its tool-use prompt intact — the same non-standard
extension pattern as `_session/steering` was before it was standardised.

## What changes

**Rust (`crates/buzz-acp/`)**

- Adds `SystemPromptTransport` enum to `acp.rs`: `Field(&str)` (ACP
protocol v2, unchanged) vs `ClaudeMeta(&str)` (new `_meta.systemPrompt:
{append: text}`). When both `ClaudeMeta` and `session_title` are present
the two `_meta` members are merged into one object so neither clobbers
the other.
- Gates on exact adapter identity
`@agentclientprotocol/claude-agent-acp` in `pool.rs`:
`session_new_system_prompt()` routes that name to `ClaudeMeta`
regardless of reported `protocolVersion` (CC declares v1).
`has_system_prompt_support()` gains the same name check so user-message
`[Base]`/`[System]` framing is suppressed for CC sessions.
- All other paths — goose post-hoc method, protocol-v2 `Field`, legacy
user-message framing — are byte-identical to before.

**Desktop (`desktop/src/features/agents/ui/`)**

- `agentSessionTranscript.ts`: the `session/new` extractor now checks
`params._meta.systemPrompt.append` as a fallback when bare
`params.systemPrompt` is absent. Bare field takes precedence. Net line
count stays at 1173 (ratchet limit).
- `agentSessionTranscript.test.mjs`: two new tests — one verifying the
`_meta` transport produces the identical standalone card (same five
sections, same `turnId: null`, same placement before the first turn) as
the bare-field transport; one proving bare field wins when both
transports are present.

## Gate claim

`@agentclientprotocol/claude-agent-acp` implies `_meta.systemPrompt`
support because the feature landed in v0.6.0 (Oct 2025, commit
`ea796f3`) before the `@zed-industries/claude-code-acp` →
`@agentclientprotocol/claude-agent-acp` package rename (Mar 2026, commit
`b409782`). The new name is therefore a reliable capability gate; the
old name falls through to the protocol-version gate (status quo, no
regression).

## Tests

- Rust: Claude append serialization; `_meta` coexistence with
`sessionTitle`; protocol-v2 bare field byte-identical; codex/old-zed
omission; claude-name support/suppression gate; old `@zed-industries`
name falls through to protocol-version gate.
- Desktop: `_meta` transport → identical standalone card; bare field
wins over `_meta` when both present.

## Pre-existing failures

`just mobile-check` and `just mobile-test` fail identically on clean
`origin/main` (5 `compose_bar` / `channels_page` tests + 3 Flutter lint
warnings) — not caused by this change. All other `just ci` jobs are
green.

6530b58a61 feat(k8s): Kubernetes backend plugin + desktop deploy path (#4289)
# Kubernetes backend plugin (crates/buzz-backend-kubernetes) + desktop
deploy path

Implements docs/remote-agents.md (merged @ 28ae6cd21) as ONE PR: the
provider
binary, the desktop changes that make it work, the harness inactivity
reaper,
the Sprig image, and the conformance/live-test suites.

Channel: buzz-remote-agents (29414326-dba7-402d-b384-b1b34d63a2e6),
thread c42b70ef.

## What's here (by lane)
- **crates/buzz-backend-kubernetes** (Dawn): stdin/stdout JSON provider,
info +
  deploy; pure classify.rs (one match arm per spec state-machine row);
reconcile/GC with ownership-marker gate + same-clock orphan check;
per-attempt
immutable Secrets; three-tier env with clear-then-write authoritative
tier.
- **Desktop** (Mari): KD3 launch block from resolved descriptor, KD5
pre-secret
negotiation gate (resolve-once → stage-and-digest → info → protocol gate
→
deploy), KD1 Windows extension strip, bundling (externalBin + Justfile +
release/canary workflows + stub loops), tauri.windows.conf.json platform
  override (Decision B: no Windows artifact).
- **buzz-acp** (Max): KD4 BUZZ_ACP_EXIT_AFTER_INACTIVITY reaper
(pool-independent;
reset only at accepted dispatch; in-flight turn/heartbeat defers, never
resets);
BUZZ_ACP_EXIT_AFTER_INACTIVITY + BUZZ_ACP_NO_PRESENCE reserved. KD8 fix.
- **Image + tests** (Perci): Dockerfile.sprig (digest-pinned bases, exec
buzz-acp
PID 1, relay-scoped credential config), image contract script, provider
conformance suites (golden wire fixtures shared with desktop tests),
live-local
  runbook (namespace-scoped, shared-cluster safe).
- **Docs** (Sami, first commit): citation re-pin c1bca1b56 → 28ae6cd21
(44/49
were already byte-exact; 3 offsets fixed) + I3 presence-bound correction
(below).

## Named spec deviations (deliberate, each with rationale)
1. **No baked default image yet.** ghcr.io/block/buzz-sprig is
unpublished
(verified: anonymous pull 403 vs control 200). Omitted `image` returns
an
   in-band field-required error instead of a default.
2. **Image override STRICTER than spec §Image:** digest-only
(`name@sha256:<64hex>`); ALL tags rejected; `name:tag@digest`
normalized.
With no baked default the override is the only path, so tag-acceptance
would
make mutability the v1 norm. Strictness is reversible; a moved tag under
an
nsec is not. Baked digest default + tag re-acceptance = follow-up with
image
   publish.
3. **imagePullSecrets not in schema (v1).** Explicit user images may
rely on
namespace-preprovisioned pull credentials — the substrate boundary.
Field
added only if the publish decision proves it necessary. 9-field budget
intact.
4. **Decision A closed: writable empty workspace.** Nest projection =
named
   follow-up; no image-side scaffolding.
5. **Decision D overridden by Tyler (event b55398d8):** provider ships
bundled
with the desktop like buzz-acp/buzz-agent; spec §Distribution's separate
   release workflow deleted for v1.
6. **I3/vision presence bound corrected 90s → 180s.** PRESENCE_TTL_SECS
moved in
#3783 during this spec's base→merge window; the number was inherited,
not
chosen. Spec :206/:216/:928 + inline quote + VISION_REMOTE_AGENTS.md:59
corrected. ← Tyler: the vision is your document; this edit is flagged
for
   your explicit eyes.
7. **Spec citations are pinned to 28ae6cd21** (main at spec merge) and
resolve
   there, not at this PR's head — this PR's own lanes move
crates/buzz-acp/src/lib.rs by ~100 lines (19 citations across
KD4/KD6/KD7/
§Stop/§Launch data). Known Defects rows fixed BY this PR retire on
merge;
   the section documents main as of the pin.
8. **KD7 grace tension declared:** pod terminationGracePeriodSeconds=60
vs
KD7's measured ~87s shutdown tail at parallelism 10 (~197s at cap 32).
   KD7 is ruled out of scope, so L1-3's "enough grace for full graceful
shutdown" is NOT met at default config — deliberate, resolved by the KD7
   follow-up, not silently.

## Question for Tyler
Will ghcr.io/block/buzz-sprig publish PUBLIC? If private-by-policy,
§Image needs
an imagePullSecrets story before the baked-default follow-up can land.

## Out of scope (named follow-ups)
KD6 exit-code contract + KD7 shutdown budget (gate OnFailure), OnFailure
restart
policy, Windows provider binary, PVCs/nest projection, mesh
deployability,
sprig image publish workflow + baked multi-arch digest default.

## Reproduce locally (four traps that cost us real time)

**1. Git hooks inherit the invoking shell's PATH — pin the shell, not
just your
verification commands.** `rust-toolchain.toml` pins `1.95.0`, but the
rustup shim
that honors that pin lives in `~/.cargo/bin`. If Homebrew's cargo is
earlier on
PATH, `cargo` in this repo is 1.89.0, which cannot build the workspace
at all:

```
$ /opt/homebrew/bin/cargo check -p buzz-db
error: rustc 1.89.0 is not supported by the following packages:
  sqlx@0.9.0 requires rustc 1.94.0
  ...                                                    # exit 101
```

Verifying with `PATH="$HOME/.cargo/bin:$PATH" cargo test` does *not*
protect the
push: lefthook's `pre-push` → `just test-unit` re-resolves `cargo` from
the
shell's own PATH, so a green local run is followed by a hook failure on
a crate
you never touched. Export the PATH for the whole shell, not per-command.
This
bit twice.

**2. Line-scope your mutations, or the mutation edits its own
detector.** When
mutation-testing the respond-to guard, a whole-file `sed` on the mode
literal
touches 5 sites — the guard *and* the fixtures/assertions that test it.
The
mutation and its detector move together and the suite stays green, which
reads
as "this code is dead" when it actually means "you deleted the
experiment":

```
# WRONG — 5 sites, guard and tests mutate together
$ sed -i '' 's/"allowlist"/"allowlist-DISABLED"/g' src/env.rs
test result: ok. 145 passed; 0 failed          # false survivor

# RIGHT — 1 site, anchored to the guard's own definition line
$ sed -i '' '/^const RESPOND_TO_ALLOWLIST/s/"allowlist"/"allowlist-DISABLED"/' src/env.rs
failures:
    env::tests::allowlist_mode_with_an_empty_list_is_refused
    env::tests::an_allowlist_entry_that_is_not_64_hex_is_refused
test result: FAILED. 143 passed; 2 failed      # real kill
```

Restore by copying a pristine file back and confirming `git diff --stat`
is
empty, not by re-running an inverse `sed`.

**3. A completeness guard is not a correctness guard.** The shared wire
fixture
`tests/fixtures/provider-wire/deploy-full-launch.request.json` passed
every test
we had while containing four classes of invented data (wrong
`respond_to`
encoding, an env key no emitter writes, allowlist entries that fail the
harness's own 64-hex rule, a `launch.env` key from no descriptor layer).
The
provider's tests could not have caught this: its types are deliberately
indifferent to these values (`Option<String>`, `Vec<String>`, arbitrary
map), so
"the provider parses it" was never evidence that the desktop emits it.
The fix
was not a stronger provider assertion but a rule about provenance —
"recorded"
means executed-and-transcribed, and the desktop's whole-object equality
test is
the only enforcement that can exist. See the fixture README.

**4. Every drift this arc was a value that agreed with itself.** Five
invented
values were found, and not one was caught by an assertion failing — each
was
caught by someone asking where a value came from. A named constant
referenced
symbolically on both the fixture and assertion side. A `sed` that
mutated its
own detector. Six probe rows that all died at the same unrelated error.
A
descriptor struct literal compared against a fixture built from that
literal
(`launch.args: ["run","--session"]`, which the resolver actually returns
as
`["acp"]`). The general defense is not more assertions but provenance: a
stub is
a control that varies nothing, and the more faithful it looks the better
it
hides. Ask what executed, not what passed.

*Fixture-test determinism caveat (post-verification, Quinn + Dawn).* The
desktop's whole-object fixture test calls the real resolver, which
consults a
process-global harness registry whose own docs require
`registry_test_lock`
for any test touching it. The fixture test holds no lock and is
nonetheless
deterministic — but by containment, not by ordering. Measured, not
derived:
planting a definition with `id: "goose"` directly into the registry
(bypassing
the loader) changes the resolved descriptor from `args: ["acp"]` to
`args: ["--poisoned"]`, so `resolve_effective_harness_descriptor`
**does**
reach the registry for this id — it does not short-circuit on the
builtin
table first. Two controls discriminate: an empty registry and a registry
poisoned under a *different* id both return `["acp"]`. What actually
protects
the test is that the registry has exactly one writer
(`update_loaded_harness_registry`, reached only via
`warm_harness_registry_from_dir`) — but that writer concatenates **two**
sources of unequal strength (`custom_harnesses.rs:319-326`). Custom
files
pass through `load_custom_harnesses`, whose `check_id_collision` rejects
the
reserved builtin id `goose` case-insensitively at the loader — and that
leg
is tested (`load_applies_id_collision_check` writes a real `goose.json`
and
asserts the loader drops it). Preset definitions
(`preset_harness_definitions`, `presets.rs:177-193`) are a bare `.map`
over
`PRESET_HARNESSES` with **no collision check** — exhaustive call-site
enumeration at `60007fda4` finds four production `check_id_collision`
sites,
none on the preset path. That leg holds only because `goose` is not in
the
preset table today (intersection of TIER1 and preset ids is empty) —
executed, not just read: adding a preset with `id: "goose"`,
`args: ["--poisoned"]` and warming via the normal preset-only path
(`warm_harness_registry_from_dir(None)`, no custom dir, no direct
writer)
flips the fixture's emitted `launch.args` from `["acp"]` to
`["--poisoned"]`
at `60007fda4`, command/env/policy_env unchanged. So: no test in the
suite
can put a `goose` entry in the registry
via the custom path, and no preset currently carries one, so no
interleaving
can perturb this fixture — containment with one checked leg and one
coincidental one. A future fixture built on a **non-builtin** runtime id
has
no containment at all — it would be order-dependent against whatever
registry-writing test ran last and must take the lock.

*Late instance, found while reviewing the mode guard.* The guard
exact-matches
`respond_to` untrimmed and case-sensitively, which is only correct if
clap's
`ValueEnum` derive is case-sensitive. `config.rs` gives two answers: the
derive
at `:448-453` carries no `ignore_case`, while the crate's own tests call
`RespondTo::from_str(s, true)` — `ignore_case = true`. Reading the
source
supports either. Measured on the built binary instead: `owner-only`
starts,
`OWNER-ONLY` / `Owner-Only` / `ALLOWLIST` / `NOBODY` all exit rc=2
`invalid
value`. Case-sensitive at the CLI, so the guard is right — and right for
a
reason the source does not state. The `from_str(_, true)` tests exercise
a
different surface and are not evidence about the CLI.

*Corollary, and the sharper half.* When a test helper **reimplements**
production instead of calling it, the helper is a fork — and a fork can
be
right while production is wrong, or wrong in the same way, and the suite
reports green either way. Both `BUZZ_ACP_ALLOWED_*` gates are forked
like this:
production compares **strings** while the helpers compare **post-parse
enums**
(`config.rs:2623`) or re-derive the split
(`buzz-cli/.../channels.rs:1296`).
Production and the helper each carry their *own* copy of the empty-entry
filter
(`:1025` and `:1300`), so fixing one says nothing about the other.
Measured on
`buzz-cli`, restoring byte-exact between runs:

| tree | result |
|---|---|
| baseline | 274 passed |
| drop the empty-filter in **production** only (the real fix) | **274
passed** — no signal |
| drop it in the **test helper** only | **273 passed, 1 failed**
(`channels.rs:1338`) |

Two independent defects, stacked, and worse together than either alone:
production can be fixed with no test ever noticing, *and* the helper
cannot be
corrected without a false alarm demanding the bug back. The root cause
is one
bit of type information — `check_allowed_channel_add_policy(allowed_raw:
&str,
..)` cannot represent "unset", while production reads `env::var(..) ->
Result`,
where unset and `""` are different states. A helper whose parameter type
can't
represent all of production's input states isn't testing production's
states —
it's testing a subset it silently chose. Same family as the
struct-literal
descriptor and the fixture drift: the test and the thing it tests
agreeing with
each other, rather than the test measuring the thing. Neither defect is
in this
PR's diff (`git diff --name-only 28ae6cd21 <head> -- crates/buzz-cli` is
empty); both are now filed as NIP-34 issues on this repo: the fail-open
+
fork-helper defect at issue event `0524a4113f2d97fd…` and the respond-to
self-lock at `e32837498969b5e7…` (filed 2026-08-02 after Quinn measured
that
no prior filing existed — zero hits on GitHub `block/buzz` open *or*
closed
and zero on the relay's kind:1621 issues, against working positive
controls). The prescription was itself
mutation-tested before being written down: repairing the fork's
signature
(`Option<&str>` + assertion → `None`) still let the reintroduced
production
bug ship 274-green — an expressive fork is still a fork; it never
executes
production. So the `buzz-cli` fix has **three parts and one explicit
keep**:
drop the production filter; **delete** the helper and point its tests at
the
real `cmd_set_add_policy` (which self-discriminates by error variant —
`Usage` = refused, `Network(BadScheme)` = passed the gate — no relay
needed);
serialize the env-var tests behind one
**`tokio::sync::Mutex::const_new`**
lock taken with `.lock().await`, including the pre-existing `:1362`
integration test (the fork was silently buying test isolation — without
the
lock, parallel runs flake nondeterministically; a `std::sync::Mutex`
held
across `.await` trips `clippy::await_holding_lock` under `-D warnings`);
and
**keep** the then-dead `!allowed.is_empty()` clause with a comment
saying
why. It is unreachable-false (`split(',')` never yields an empty vec),
but it
is the only thing that keeps the reintroduced production bug detectable
—
mutation-tested: on a tree that deletes the clause, reintroducing the
empty-filter bug survives 275/0, because `""`/`","`/`" "` refuse either
way
and the filter goes semantically inert. Dead code can be load-bearing
for
tests: "provably unreachable" is an argument about behavior, never about
coverage. When a helper forks production, the fix has to delete the
fork:
any change that leaves two implementations standing can only ever be
verified against the one the tests call. *Final shape:* the keep and the
broad lock are both artifacts of the fork surviving in some form. The
extraction variant (Dawn, mutation-tested at `60007fda4`) removes the
tension: extract one `check_channel_add_policy_allowed(Option<&str>,
&str)`
that **production calls**, with the `Option` placed at the env boundary
where the `Result<String, VarError>` bit actually lives. 5/6 mutants
killed; the empty-filter survivor is proven **equivalent** (exhaustive
6174-pair check, 0 divergences, with a diverging negative control;
independently re-derived by a second generator — different tokens and
shape — 0 divergences on admitted policies, 500 on a non-admitted
control),
not a coverage hole — on a one-implementation tree there is no fork left
to
witness, so no dead clause needs keeping. One scope line on that
equivalence: it is **caller-conditional**, a property of the only
current
caller, not of the gate function — `cmd_set_add_policy`'s own match at
`:1027-1034` admits only three policies before the gate runs; a second
caller reaching the gate with arbitrary strings resurrects m1 as a real
hole. The lock does not disappear, it
narrows (Dawn's own correction, caught by Mari): lock exactly the tests
that mutate the process env — three-plus-one on a fork tree, two on the
extraction tree — behind one `tokio::sync::Mutex`, and the lock is part
of
the assertion, not hygiene: with it deleted, the gate test fails 8/8
runs
deterministically by receiving `Network(BadScheme)` where it expects
`Usage` — the unset test's `remove_var` clobbers the other's `set_var`,
and
**the gate test passes straight through the gate**, a false negative on
the
exact authz assertion the test exists to make. State it as an outcome:
these two tests must not observe each other's env writes. 276/0 stable
across 5 parallel runs, clippy `-D warnings` clean; independently
verified
(patch applied to a second worktree: result blob `d67e584be` matches the
patch index, full mutant matrix reproduces row for row). One new row no
earlier
prescription covered: collapsing unset into `Some("")` fails **closed**
—
an unconfigured deployment refuses every policy — killed by the unset
test.
Patch: `OUTBOX/BUZZ_CLI_ADD_POLICY_GATE_EXTRACT_FIX.patch`. The filed
issue
(`0524a411…`) carries the fork-shape prescription; whoever picks it up
should prefer the extraction shape, drop the dead-clause keep with it,
and
keep part 3 outcome-shaped: serialize whichever tests mutate the env.

b1b283cd4c fix(buzz-acp): thread cache-read tokens into NIP-AM kind:44200 events (#3999)
## Problem

`buzz-agent` measures and sends `accumulatedCachedInputTokens` on the
wire (`usage.rs:93`). `buzz-acp` deserializes it correctly — but then
drops it: `TurnUsage` had no cache field, and `build_turn_metric_counts`
hardcoded `cache_read_tokens: None` and `cache_write_tokens: None` into
both `turn` and `cumulative` `TokenCounts`. Every kind:44200 event
published permanently lacked data the harness measured. The archive is
append-only — this is unrecoverable data loss per turn, every turn,
until fixed.

NIP-AM already specifies the fields (`cacheReadTokens` /
`cacheWriteTokens` inside `turn` and `cumulative`). This is a pure
threading fix.

## Changes

**`crates/buzz-acp/src/usage.rs`**

- `SessionState` gains `last_cached_input: u64` to track the committed
cache-read baseline.
- `TurnUsage` gains `turn_cache_read_tokens: Option<u64>` (field-local;
`None` when no baseline or counter decreased) and
`cumulative_cache_read_tokens: u64` (always present; zero when no cache
hits reported).
- `record()` computes the cache-read delta with field-local taint
semantics: a decrease in the cumulative counter nulls only
`turn_cache_read_tokens` — it does not flip `delta_reliable` or
invalidate `turn_input_tokens`/`turn_output_tokens`. Identical to the
`accumulatedTotalTokens` pattern already present.
- `take()` and the setup-notification branch both advance
`last_cached_input` in the committed baseline.

**`crates/buzz-acp/src/pool.rs`**

- `build_turn_metric_counts` wires `turn_cache_read_tokens` into
`turn.cache_read_tokens` (when `delta_reliable`) and
`Some(cumulative_cache_read_tokens)` into
`cumulative.cache_read_tokens`.
- `cache_write_tokens` remains `None` on both counts with an explanatory
comment: buzz-agent does not emit a write-side count on the wire today.
- Six existing `TurnUsage` struct literals in tests updated with the two
new fields.

## Tests

**`usage.rs` — new cache-read section (5 tests):**
-
`cache_read_first_turn_produces_none_turn_delta_and_passes_cumulative_through`
— no baseline → delta None, cumulative passes through
- `cache_read_second_turn_delta_computed_correctly` — delta = current −
previous
- `cache_read_decrease_nulls_turn_cache_but_leaves_delta_reliable` —
field-local taint: decrease nulls cache delta only, input/output stay
reliable
- `cache_read_zero_payload_after_baseline_produces_zero_delta` — zero on
both sides → `Some(0)`, not `None`
- `cache_read_threads_through_setup_notification_baseline` — setup
notification baseline correctly seeds the cache counter

**`pool.rs` — new acceptance test (1 test):**
- `test_build_turn_metric_counts_cache_read_tokens_thread_through` —
wire-parses a buzz-agent payload with nonzero
`accumulatedCachedInputTokens`, runs two turns through the tracker and
`build_turn_metric_counts`, and asserts nonzero `cacheReadTokens` in
cumulative + correct per-turn delta in `turn`; also asserts
`cache_write_tokens` is `None` throughout

## Quality gates at tip `c6405eb43f532572e3b7775e0dee826dc9cb3f82`

| Gate | Result |
|---|---|
| `cargo test -p buzz-acp` | **655/655**, 0 failed |
| `cargo clippy -p buzz-acp --all-targets -- -D warnings` | clean |
| `cargo fmt --check` | clean |

Note: the pre-push hook `mobile-test` gate fails on `origin/main` before
this branch (Flutter test in `channels_page_test.dart` /
`compose_bar_test.dart` — verified independently). My changes touch only
`crates/buzz-acp/src/`; the mobile failure is unrelated and
pre-existing.

53771c8f54 fix(acp): preserve truncated thread context (#3340)
## Why
Long Buzz threads were rendered as `[Thread Context (13 of 13
messages)]` because the harness counted only the already-limited query
result. That hid older context and could also hide the agent's own prior
reply in busy threads.

## What
- Fetch one extra thread reply as a sentinel so truncated context is
labeled correctly.
- Use a best-effort `/count` call for improved truncated totals when
available, clamped to the sentinel-proven minimum so racy counts cannot
render impossible labels.
- Keep the `/count` path single-attempt with a short timeout and only
add the root to exact totals when the root was actually fetched.
- Fetch and preserve the agent's newest prior reply when it falls
outside the recent window, with exact event-id matching for the
pin/dedup boundary.
- Add parser and fetch-boundary tests for truncation, exact count,
missing root, count-below-minimum clamping, count failure fallback,
distinct fetched-reply lower bounds, agent-reply dedup/pinning, and
serialized query/count filter semantics.

## Risk Assessment
Low-to-medium — limited to buzz-acp prompt context fetching and a small
RestClient helper. If `/count` fails or times out, the code falls back
to the sentinel-derived minimum total rather than failing the prompt.
The synchronous `/count` happens only for truncated thread contexts and
is bounded to one short best-effort attempt.

f95fdc1a10 feat(agent,acp): wire provider total_tokens through NIP-AM publish chain (#3593)
## What

Wires genuine provider-reported `total_tokens` through the full
buzz-agent → buzz-acp publish chain so kind-44200 events carry real
per-turn and cumulative totals for OpenAI-backed models, while
preserving all existing behaviour for Anthropic and external harnesses
(goose, claude-code).

## Why

Live prod data showed 0 of 1,934 archived reports carry `totalTokens`.
Both hardcoded `total_tokens: None` in `pool.rs` and the absent field in
`buzz-agent`'s parser are root causes. This is the backend half of a
two-track fix; the display-fallback half lands in
[#2035](https://github.com/block/buzz/pull/2035).

## Changes

**`crates/buzz-agent/src/types.rs`**
- Added `total_tokens: Option<u64>` to `LlmResponse` with an explicit
doc comment that NIP-AM forbids deriving it.
- Added `TurnTotalState` enum (`Unseen | Exact(u64) | Unknown`) with
`fold()` and `exact_value()` — the tri-state accumulator that
distinguishes not-yet-observed from permanently poisoned.

**`crates/buzz-agent/src/llm.rs`**
- `parse_responses` and `parse_openai`: read `usage.total_tokens` from
OpenAI Chat Completions (including Databricks routes) and the Responses
API via `sum_usage`.
- Anthropic: explicit `total_tokens: None` — no genuine total available;
NIP-AM forbids summing categories.

**`crates/buzz-agent/src/agent.rs`**
- Added `turn_total_state: &'a mut TurnTotalState` to `RunCtx`.
- Fold `response.total_tokens` into the accumulator after each
usage-bearing response; non-usage-bearing responses (keepalive/stream
frames) do not poison.

**`crates/buzz-agent/src/lib.rs`**
- Added `accumulated_total_state: TurnTotalState` to `Session` (default
`Unseen`).
- Per-turn state passed to `RunCtx`, folded into session cumulative
after each turn.
- Emits `accumulatedTotalTokens` in `usage_update` only when cumulative
is `Exact(n)`.

**`crates/buzz-acp/src/usage.rs`**
- Added `accumulated_total_tokens: Option<u64>` (serde default) to
`UsageUpdatePayload` — optional for goose compat.
- Added `last_total: Option<u64>` to `SessionState`.
- Added `turn_total_tokens` and `cumulative_total_tokens` to `TurnUsage`
(field-local — never affect `delta_reliable`).
- Derive turn-total delta only when prev and current are both `Some` and
monotonic; absence, decrease, or no baseline leaves only the total delta
null without touching input/output reliability.

**`crates/buzz-acp/src/pool.rs`**
- Replaced both hardcoded `total_tokens: None` in
`publish_agent_turn_metric` with `usage.turn_total_tokens` and
`usage.cumulative_total_tokens`.

## Tests

20 new tests across the four touched files:

| File | Tests |
|------|-------|
| `types.rs` | `TurnTotalState` fold, accumulation, exact_value, default
(7 tests) |
| `llm.rs` | Chat present/absent, Responses present/absent, Anthropic
always-None (5 tests) |
| `usage.rs` | First turn no baseline, second-turn delta, cumulative
decrease (field-local), current absent, goose-shaped deserialization,
baseline absent (6 tests) |
| `pool.rs` | Exact turn+cumulative mapping, null totals never derived
(2 tests) |

`cargo test -p buzz-acp -p buzz-agent` — all passing, 0 failures.

## Scope

Boundary: `crates/buzz-agent/**` + `crates/buzz-acp/**` only. Desktop
unchanged.
`costUsd` explicitly out of scope.

7adc46268d feat(cli): mirror Desktop mention delivery (#3330)
🤖
## Summary

Agent-authored mentions currently depend on matching visible `@Name`
text to channel profiles. That makes notification delivery ambiguous
when names collide or profiles change, and it encourages an extra
post-send lookup just to confirm that the intended `p` tags were
emitted.

This change makes `buzz messages send` mirror Desktop's existing model:
the message keeps a readable name in its content while the recipient
pubkey is supplied separately.

```bash
buzz messages send \
  --channel <UUID> \
  --content '@Alice could you review this?' \
  --mention <alice-hex-or-npub>
```

`--mention` is repeatable. The CLI normalizes and deduplicates explicit
pubkeys, merges them with any names it can resolve from the channel, and
gives explicit identities priority under the existing 50-mention limit.

Before uploading attachments, signing, or publishing, the command checks
every resulting pubkey against the channel's current membership:

- Members are mentioned normally.
- Non-members stop the send and produce an actionable error.
- `--allow-non-member-mentions` deliberately sends notifying `p` tags
without adding anyone to the channel.

Sending a message never changes membership. On success,
`mention_pubkeys` is read from the exact signed event and returned with
the relay response, so callers can verify the emitted recipients without
another query.

Managed-agent guidance teaches this single-command mention flow. Desktop
mention behavior and the Nostr event schema are unchanged. Forum
guidance is intentionally handled separately in #3596.

### Related issue

None found. This replaces the earlier guidance-only approach in this PR
with the underlying CLI behavior it required.

### Testing

- `cargo test -p buzz-sdk`
- `cargo test -p buzz-cli`
- `cargo test -p buzz-acp`
- `cargo test --manifest-path desktop/src-tauri/Cargo.toml`

Will PflegerandGitHub ddd468723a revert(acp): remove dead GOOSE_ACP_SCHEDULER_DISABLED env injection (#3576)
## Summary

[block/buzz#3144](https://github.com/block/buzz/pull/3144) injected
`GOOSE_ACP_SCHEDULER_DISABLED=true` into every `AcpClient::spawn` call
as a forward-compatible no-op, intended to suppress the cron scheduler
in goose ACP children once the matching reader landed in goose. That
reader only ever existed in
[aaif-goose/goose#10738](https://github.com/aaif-goose/goose/pull/10738),
which was closed unmerged.

[goose#10781](https://github.com/aaif-goose/goose/pull/10781) (Lifei
Zhou, merged 2026-07-29) disables the ACP scheduler by default at the
source: `goose acp` now requires `--enable-scheduler` to start a
scheduler. Buzz-spawned children therefore get no scheduler with zero
configuration — making the `GOOSE_ACP_SCHEDULER_DISABLED` injection
permanently dead code.

## What changes

Removes from `crates/buzz-acp/src/acp.rs`:

- `GOOSE_SCHEDULER_DISABLED_ENV` constant
- `cmd.env(GOOSE_SCHEDULER_DISABLED_ENV, "true")` injection in
`AcpClient::spawn`
- `spawn_injects_scheduler_disabled_env_by_default` test
- `spawn_scheduler_disabled_env_overrides_conflicting_extra_env` test
- `spawn_and_read_child_env` helper (unreferenced once the two tests
above are gone)

No other files are affected.

## Why now

Leaving dead code that references an env var no reader will ever consume
misleads future maintainers about the actual scheduler-isolation
mechanism. The isolation is now an upstream default, not a Buzz
injection.

4a1ebf25c7 feat(agent): make Gemini and MLflow-route models usable through databricks_v2 (#3569)
## Summary

Makes Gemini — and every other non-Claude, non-GPT-5 model on the
Databricks MLflow route (`databricks_v2`) — usable in an agent loop.
These are the non-`benchmarks/` changes from
`benchmark/harness-accounting-and-solo`, lifted onto a clean base off
`main` so they can land independently while the harness work continues.

Two defects made these models unusable, one fatal and one silent. Both
live only in `openai_body` / `parse_openai`, which is the
least-exercised of the three `databricks_v2` sub-routes — the
`luna`/`sol` conditions run the Responses route and the `opus`
conditions run the Anthropic route, so **this change is inert for every
model already in use** and only lights up the MLflow path.

## Why a third route at all

`databricks_v2_route_for_model` buckets by model family: `claude*` →
Anthropic Messages, `gpt-5`/code-names → OpenAI Responses, **everything
else → MLflow chat-completions**. Gemini, Qwen, gpt-oss, and friends all
fall through to that third pair — and both bugs below live only there.

## D1 — dropped thought signatures (fatal)

Gemini returns a `thoughtSignature` on every tool call and **requires it
echoed back**. `openai_body` reserialized each call as `{id, type,
function}` only, dropping the field, so the next request 400'd:

```
HTTP 400  Function call is missing a thought_signature in functionCall parts.
```

For a coding agent this fires on the **first** tool call, so the model
never completes a single turn.

**Position is load-bearing.** A four-shape replay probe against the live
gateway established that the signature must sit as a *sibling* of
`function` — nesting it inside `function{}` fails with the *same* 400 as
omitting it. A fix that "preserves the field" without preserving its
position passes a unit test and still 400s.

The fix: `ToolCall` gains `provider_extra: Map<String, Value>`.
`parse_openai` captures every top-level wire key except the three we
model (`id`, `type`, `function`); `openai_body` re-emits them beside
`function`. Keeping *whatever we did not model*, rather than naming
`thoughtSignature`, means the next provider with an opaque per-call
token needs no change here. The Responses and Anthropic replay shapes
are fully modelled, so they pass `Default::default()` and stay
**byte-identical** to before.

### D1b — duplicate tool-call ids (same root cause)

Gemini returns the **function name** as the id, so two parallel calls to
one function arrive sharing an id — and that id is what pairs a
`role:"tool"` result back to its call, making two results
indistinguishable. `dedupe_provider_ids` suffixes collisions
(`get_weather`, `get_weather-2`). Safe because both halves of the
pairing (the assistant `tool_calls[].id` and the result's
`tool_call_id`) are re-emitted from this same value; the provider never
sees its original id again.

## D2 — block-array content discarded (silent, worse than a crash)

`parse_openai` read `content` with `as_str()`, which returns `""` for
anything that isn't a JSON string. Gemini (and Qwen35, gpt-oss) send an
array of typed blocks:

```json
"content": [
  {"type": "reasoning", "summary": [{"type": "summary_text", "text": "…"}]},
  {"type": "text", "text": "391"}
]
```

So the model answered and the answer was thrown away — no error, no
warning, just a turn that looked like the model had said nothing. On a
benchmark this reads as "Gemini is bad at the task" rather than "buzz
dropped the reply."

`openai_content_parts` now accepts either shape — string as before, or a
block array where `text` blocks concatenate into text and `reasoning`
blocks into reasoning (Gemini nests the prose one level down under
`summary`). Message-level `reasoning_content` / `reasoning` still win
when present, so DeepSeek and vLLM-style hosts are unchanged; block
reasoning is the last fallback.

## Also: a turn-start log line (`buzz-acp` `pool.rs`)

Small, independent observability change that also rides in the
non-benchmark delta: `run_prompt_task` now emits a `pool::prompt` "turn
starting" line, labelled by the same `prompt_label` helper as
`log_stop_reason`, so a log reads as start/stop pairs. An unpaired start
is the only durable evidence that a turn was entered and never returned
— without it, a stalled agent and an agent nobody woke leave identical
(zero-completion) logs.

## Interaction with #3538

#3538 (already merged) rewrote `databricks_v2_route_for_model` to route
by boundary-aware model-family segments. That change and this one touch
**different functions** in `llm.rs` — routing vs. body/parse — and
compose cleanly; the family routing decides *which* pair runs, and this
fixes the MLflow pair it can now select.

## Testing

- `cargo fmt --all -- --check`, `cargo clippy -p buzz-agent -p buzz-acp
--all-targets -- -D warnings` — clean.
- `cargo test -p buzz-agent -p buzz-acp` — all green (304 + 632 lib
tests plus integration suites, 0 failures). Five new tests cover:
block-array text extraction, plain-string regression, passthrough
capture (and non-duplication of the modelled keys), replay position
(`thoughtSignature` beside `function`, not inside it), and id
de-duplication.
- Wire evidence: the four-shape replay table and the reasoning-effort
probe were run against `block-lakehouse-staging` (recorded in the design
doc).

## Relationship to the benchmark branch

The full design write-up (four-shape replay table, position-matters
analysis, effort verification, and open pricing item) lives in
`docs/08-gemini-provider-fixes.md` on
`benchmark/harness-accounting-and-solo`. The benchmark manifests and
endpoint-config entries that exercise these models are separable and
stay on that branch.

9beb3b8c6e fix(cli): mask credential env values in --help output (#3570)
clap renders live env var values in help text by default. Three args
carrying credentials were exposed this way:

- `BUZZ_PRIVATE_KEY` in `buzz-cli` (`crates/buzz-cli/src/lib.rs`)
- `BUZZ_AUTH_TAG` in `buzz-cli`
- `BUZZ_PRIVATE_KEY` in `buzz-acp` (`crates/buzz-acp/src/config.rs`)

Add `hide_env_values = true` to each. Env var names remain visible for
discoverability; only their runtime values are withheld from `--help`
output.

Also adds a regression guard in each crate's test module that walks the
clap command tree (recursing into subcommands for `buzz-cli`) and
asserts every arg whose env var name contains `KEY`, `SECRET`, `TOKEN`,
`PASSWORD`, `CRED`, or `AUTH` has `hide_env_values` set. This prevents
future credential-bearing args from being added without the masking in
place.

c405ad1d4b feat(agent): fix Anthropic prompt caching with Databricks (+ MCP proxy/TLS passthrough) (#3463)
> On 8 tasks matched by name across the two runs, cost fell $8.36 →
$1.77 (4.71×) and wall-clock 12,423 s → 1,085 s (11.45×).

## Summary

Two independent, self-contained fixes to `buzz-agent`/`buzz-acp`, split
out of the benchmark branch so they can land while the harness work
continues:

1. **Request and surface Anthropic prompt caching.** buzz never sent a
`cache_control` breakpoint, so on the Databricks Anthropic route
`cache_read_input_tokens` was **structurally always 0** and the ~10×
cache-read discount was never claimed. This teaches `anthropic_body()`
to mark the cacheable prefix, and plumbs the cache split end-to-end so
accounting can price it.
2. **Pass proxy + TLS-trust env into MCP tool subprocesses**, so agent
tools on a proxy-only host stop reporting a live network as offline.

## Why the caching gap matters

The Anthropic Messages API does **not** cache unless the request carries
a `cache_control` breakpoint, and the Databricks AI Gateway — a
third-party proxy in front of the model, in the same category as
Bedrock/Vertex — does **not** auto-cache (only the first-party Anthropic
API and Claude-on-AWS do zero-config caching). So every request was
billed cold.

Measured live against the Databricks gateway
(`databricks-claude-opus-5`, 2026-07-28), the same call with and without
a single `cache_control` marker:

| Run | `input_tokens` | `cache_creation` | `cache_read` | latency |
|---|---|---|---|---|
| No `cache_control`, two byte-identical calls | 121,625 | 0 | **0** |
~9.3 s |
| With one marker — cold (write) | 4 | 121,625 | 0 | 9.3 s |
| With one marker — warm (read) | 4 | 0 | **121,625** | **4.5 s** |

One marker moved 121,625 tokens from full-price input to a 0.1× cache
read and roughly halved latency (a clean, isolated ~2.07× prefill
speedup on this single-threaded microbenchmark). The gateway honours
`cache_control`; buzz simply never sent it.

At fleet scale this was a real budget item. Across matched
Terminal-Bench solo sweeps (89 tasks, `-n 20`, before the fix), the two
OpenAI-route models independently landed at ~86–87% cache reads — the
expected shape for an agentic loop, where system + tools + append-only
history repeat every turn — while the Anthropic route returned a hard 0%
on every receipt:

| Condition | Route | Input tokens | Cache reads | Cost | Cost if
uncached | Discount |
|---|---|---|---|---|---|---|
| luna (`gpt-5-6`) | OpenAI | 20,320,818 | **17.7M (87.0%)** | $6.96 |
$22.87 | **3.28×** |
| sol (`gpt-5-6`) | OpenAI | 22,312,290 | **19.2M (85.9%)** | $37.07 |
$123.35 | **3.33×** |
| opus (`claude-opus-5`) | Anthropic | 12,459,822 | **0 (0.0%)** |
$81.31 | $81.31 | **1.00×** |

Applying luna's measured 87% read rate to the opus token counts at list
prices (`input $5/M`, `cached_input $0.5/M`, `output $25/M`) puts the
opus run at **~$32.53 vs the $81.31 actually paid — a ~60% overspend on
those 49 trials (~$89 on a full sweep)**. That is an upper bound (it
prices every cached token at the 0.1× read rate and ignores the 1.25×
write premium), and the opus discount is structurally smaller than
luna/sol's because opus emits ~3.5× more uncacheable output per trial,
which sets a floor on what caching can recover.

There is also a plausible **second-order effect**: Databricks appears to
meter its per-minute rate limit on *uncached* input tokens, so the
missing cache also cost rate-limit headroom — the opus endpoint lost 63%
of its trials to fatal 429s while running alone at one-third of a GPT
endpoint's raw throughput. This is a hypothesis, not a proven mechanism
(the only zero-cache condition is also the only Anthropic endpoint), but
it is the reading that explains the throttling with one rule instead of
two.

## Post-fix results (provisional — first trials of an in-flight re-run)

On 8 tasks matched by name across the two runs, cost fell **$8.36 →
$1.77 (4.71×)** and wall-clock **12,423 s → 1,085 s (11.45×)**.

| Metric | before (`4a955a858`) | after (`3bef1f6a`) |
|---|---|---|
| Cache reads as % of input | **0.0%** | **78.7%** (still climbing
toward the ~86% steady state) |
| `cost_usd_no_cache_discount / cost_usd` | **1.00×** | **2.18×**
(tracking the projected ~2.5×) |
| Trials with a fatal 429 (same `-n 20`) | **63%** | **15–19%** |

To be clear about attribution: **~2× of that is the clean prefill saving
from caching itself**; the rest is second-order — cached requests burn
far less rate-limit budget, so they stall less and redo less destroyed
work. The 11.45× is a system-level result specific to this throttled
workspace, not a caching benchmark. Quality held (7/8 solved in each
run). A controlled low-`-n` A/B (neither arm hitting a 429), which the
`BUZZ_AGENT_PROMPT_CACHING` opt-out exists to enable, is still owed
before this becomes a published claim.

## What changed

### 1. Request caching (`llm.rs`, `config.rs`)

`anthropic_body()` emits ephemeral `cache_control` breakpoints, gated by
`BUZZ_AGENT_PROMPT_CACHING` (**default on**, `=0` to opt out):

- **Static prefix** — marker on the `system` block. Prefix order is
`tools → system → messages`, so this single marker caches **tools +
system** together. Byte-identical on every turn of a run, and survives a
context handoff (system/tools come from cfg/mcp, not `self.history`).
- **Rolling tail + leapfrog** — marker on the last block of the last
**two** messages. The append-only history re-reads the prior turn's
prefix from cache; marking two messages (not one) keeps consecutive
breakpoints inside Anthropic's **20-block lookback window** even as tool
parallelism rises, avoiding a silent full-price miss.

An empty system prompt stays a bare string (Anthropic rejects empty text
blocks), and below-threshold prefixes are silently not cached, so the
flag is safe on by default.

### 2. Surface the cache split end-to-end — the plumbing (`types.rs`,
`llm.rs`, `agent.rs`, `lib.rs`, `usage.rs`, `acp.rs`)

This is the part that makes gaps like the one above **visible** instead
of silent. A consumer that prices all of `input_tokens` at the full rate
can't tell a route that's caching from one that isn't — the total looks
right either way. So:

- `LlmResponse` gains `cached_input_tokens` (a **subset** of
`input_tokens`, never an addition); `parse_anthropic` / `parse_openai` /
`parse_responses` each populate it.
- A `usage_first()` helper reads the cache count wherever a provider
hides it — flat `cache_read_input_tokens` (Anthropic),
`prompt_tokens_details.cached_tokens` (OpenAI chat),
`input_tokens_details.cached_tokens` (Responses) — taking the **first
present value, never a sum**. Reading only flat keys is exactly why the
OpenAI route's nested `cached_tokens` had *also* been going unclaimed:
`prompt_tokens` is already inclusive, so the total looked correct while
the discount silently went unreported.
- The per-turn/per-session accumulators and the goose `usage_update`
payload now carry `accumulatedCachedInputTokens`; `buzz-acp`
deserializes it (`serde` default `0` for goose, which doesn't send it)
and logs `cached=<n>`.

### 3. Fix a Databricks MLflow-route double-count (`llm.rs`)

The Databricks MLflow route reports the flat Anthropic-spelled
`cache_read_input_tokens` *alongside* an already-inclusive
`prompt_tokens`, so the old code summed them and nearly doubled the
count — inflating both the context-budget gate and cost.
`openai_chat_input_tokens()` now reads `prompt_tokens` alone. Verified
on a live `databricks-glm-5-2` response where `prompt_tokens +
completion == total` proves inclusivity. (Anthropic's native route
genuinely *excludes* the cache fields and is still summed — the two
never collide, because `claude*` models route to the Anthropic path.)

### 4. Proxy + TLS-trust passthrough into MCP tools (`mcp.rs`) —
independent fix

`buzz-agent` `env_clear()`s each MCP child, and the allowlist carried no
proxy/TLS vars. On a proxy-only host that doesn't degrade the tools, it
**blinds** them: apt, curl, pip, git connect directly, the egress
firewall resets the socket, and the agent reports "Connection reset by
peer" — indistinguishable from a genuinely offline task. Adds both
spellings of `HTTP(S)_PROXY`/`NO_PROXY`/`ALL_PROXY` (curl/git read
lowercase; Go/Python read uppercase; libcurl ignores uppercase
`HTTP_PROXY`) plus `SSL_CERT_FILE`/`SSL_CERT_DIR` for TLS-terminating
proxies that present their own CA.

## Testing

- `cargo fmt --all -- --check`, `cargo clippy -p buzz-agent -p buzz-acp
--all-targets -- -D warnings` — clean.
- `cargo test -p buzz-agent -p buzz-acp` — **all green** (632 + 299 lib
tests plus integration suites, 0 failures). New tests cover: the three
breakpoints and the disabled/empty-system/single-message edge cases;
nested-vs-flat cache parsing for all three routes; the Databricks
inclusive-`prompt_tokens` fix; wire deserialization of
`accumulatedCachedInputTokens`; and the proxy/TLS passthrough allowlist.
- Pre-push lefthook suite green (branch-skew, rust-tests, test,
desktop-check/test/tauri).

## Relationship to the benchmark branch

These are the non-`benchmarks/` changes from
`benchmark/harness-accounting-and-solo`, lifted onto a clean base off
`main` so they can merge independently.

6300a6b1d0 fix(acp): per-runtime env defaults at spawn — isolate Hermes from configured MCP startup (#3420)
## Summary

- add a generic per-runtime env-defaults table,
`config::default_agent_env()`, mirroring the existing
`default_agent_args()` / `codex_network_env()` precedent, and merge it
once in `AcpClient::spawn` with the established precedence: **runtime
defaults < persona `extra_env` < inherited parent env**
- first (and only) row: Buzz-owned Hermes processes get
`HERMES_ACP_SKIP_CONFIGURED_MCP=1`, so Hermes does not preload unrelated
profile-configured MCP servers before answering ACP `initialize` (fixes
the 10s model-discovery timeout in #3355 — Buzz supplies session MCP
servers explicitly through `session/new`, per Hermes's documented
host-integration contract for this variable)
- normalize Windows `.cmd`/`.bat` shims alongside `.exe` in
`normalize_agent_command_identity` (npm installs resolve to those
wrappers)
- switch the `extra_env` parent-presence check from `var()` to
`var_os()` so non-UTF-8 parent values are honored

Replaces the runtime-specific approach in #3386: same behavior, but the
mechanism is generic runtime spawn metadata in `config.rs` rather than a
Hermes/ACP special case in `acp.rs`, and the seam covers every launch
path (Desktop spawn, `buzz-acp models`, CLI) because they all funnel
through `AcpClient::spawn`. ~15 lines of production code.

Fixes #3355

## Testing

- `cargo test -p buzz-acp` — **639 passed, 0 failed** (full package,
includes the new `default_agent_env_recognizes_hermes_identities` unit
test and `spawn_applies_runtime_env_defaults_with_extra_env_precedence`
integration test covering default injection, extra_env override, and
non-Hermes exclusion)
- `cargo fmt --all -- --check`, `cargo clippy -p buzz-acp --all-targets
-- -D warnings` — clean
- live-local with real Hermes v0.19.0 (`hermes-acp`): `buzz-acp models`
returned **13 models / currentModelId in 2.6–3.0s** (was a 10.0s timeout
on the first cold run without isolation); a wrapper probe confirmed the
child received `HERMES_ACP_SKIP_CONFIGURED_MCP=1` by default and `0`
when the parent env set it explicitly (operator wins)
- lefthook pre-push suite green: rust-tests, desktop-check,
desktop-test, desktop-tauri-test, mobile-test, branch-skew

No UI changes; subprocess environment behavior only.

f25e6dd6aa feat(acp): steer claude-code and codex agents via _session/steering (#3007)
Mid-turn steering was reachable only through goose's
`_goose/unstable/session/steer`, which requires an `expectedRunId`
sourced from `_meta.goose.activeRunId`. claude-agent-acp and codex-acp
never emit a run id, so every mid-turn mention to those harnesses bailed
at the run-id guard before writing a byte and degraded to cancel +
merge, destroying in-flight tool calls.

Both adapters ship `_session/steering` (params `{sessionId, prompt}`,
result `{outcome}`) and advertise it as `_meta.steering.supported` on
the `initialize` response. This adds it as a second steer transport
selected at write time, reusing the existing withhold/release, ack
routing, and cancel+merge fallback machinery unchanged.

## Transport selection

| `active_run_id` | `steering_supported` | Transport |
|---|---|---|
| `Some(run_id)` | any | `_goose/unstable/session/steer` +
`expectedRunId` (unchanged) |
| `None` | `true` | `_session/steering` with `{sessionId, prompt}` |
| `None` | `false` | ack `ExpectedRunIdMissing`, write nothing
(unchanged) |

goose keeps priority when both are present — `expectedRunId` is strictly
more precise about *which* run is being steered.

## Two load-bearing safety properties

**The advertised capability is the only gate — never error-code
probing.** codex-acp's `extMethod` answers unrecognized extension
methods with a bare `{}`, which is a JSON-RPC *success* rather than
`-32601`. Buzz maps a steer success to `queue.remove_event`, so probing
an unknown method would silently delete the user's message with no
error, no fallback, and no log line.

**An `outcome` must be positively recognized.** Only `injected` and
`startedNewTurn` count as delivery. Anything else — codex's `failed`, an
unknown value, or a missing `outcome` entirely — is
`SteerError::OutcomeRejected`, which releases the withheld event and
fires the cancel+merge fallback. This makes the silent-loss path above
unreachable even if an adapter mis-advertises.

`startedNewTurn` acks `Success`, because the message really was
delivered and must not be redelivered, but deliberately does **not**
renew the read loop's hard deadline: the turn Buzz was awaiting had
already settled, and renewing would extend the clock on a finished turn.

## Notes for reviewers

- `SteerError::OutcomeRejected` needs no new arm in the
`PoolEvent::SteerAck` match — the existing catch-all
`Ok(SteerAck::Err(_)) => (true, false, true)` already gives release +
fallback, and the two `AgentError` arms above it match that variant
specifically, so they do not shadow it.
- Comments that described the old goose-only "try-and-tolerate" `-32601`
behavior are corrected; that assumption was never valid for codex-acp.
- No CI job runs `buzz-acp` tests. The full package suite was run
locally: **617 passing, 0 failing**.

Will PflegerandGitHub 1d4f97b959 fix(acp): disable goose cron scheduler in managed agent children (#3144)
A Buzz install with a scheduled goose recipe fires each cron entry once
per `goose acp` child instead of once, because every child
unconditionally starts its own cron scheduler over the shared
`~/.local/share/goose/schedule.json`. With a pool of N children per
harness and multiple harnesses, one scheduled recipe fans out to N ×
harness_count executions — each running under the managed agent's
identity rather than the operator's, and racing the operator's own
standalone goose over the same schedule file.

This injects `GOOSE_ACP_SCHEDULER_DISABLED=true` into every child
spawned by `AcpClient::spawn`, so a managed agent never owns the
operator's cron schedule.

## Placement

The `cmd.env` call is set last — after the `extra_env` operator-wins
loop and after the `CODEX_CONFIG` merge — deliberately with no escape
hatch. Managed children not running the operator's schedule is a
correctness invariant rather than an operator-tunable default, so the
injection must beat both a conflicting persona `extra_env` entry and any
value inherited from the parent process.

It is injected for all agents, not just goose. Agent builds that don't
recognize the variable ignore it.

## Sequencing

The goose-side flag that reads this variable and skips scheduler startup
lands separately (repo TBD). Until it does, this change is a
forward-compatible no-op: it sets an environment variable nothing
currently reads. Merging it first means no coordinated release is needed
— the fix takes effect as soon as the goose side ships.

925a9a7bf2 fix(buzz-acp): accept id-keyed config options when resolving model switch (#2795)
## Summary

Fixes #2794. Related: #2692.

`resolve_model_switch_method()` reads the `configId` key from each
`session/new` `configOptions` entry and skips entries that lack it.
`claude-agent-acp` (v0.61.0) keys its entries with `id`, so every
model-category entry was skipped, the desired model never matched, and
Claude Code sessions fell back to the CLI default from the user's
`~/.claude/settings.json`. The only trace was a `pool::model` WARN that
never reaches the per-agent log files.

This is the ACP-side half of the symptom reported in #2692. The open
desktop-side PRs (#2695, #2701, #2696) inject `ANTHROPIC_MODEL` at
spawn, which masks the problem for spawn-time selection but leaves the
config-option switch path broken.

## Changes

- `resolve_model_switch_method()` accepts either `configId` or `id` when
extracting the config id. The set request is unchanged: the ACP SDK
schema takes `configId` as the request param and the adapter resolves it
against its `id`-keyed entries, so only the read side needed fixing.
- Regression test with an `id`-keyed `configOptions` payload mirroring
the real adapter response (including `models: null`, so the unstable
fallback path cannot rescue the match).
- Doc comment on `extract_model_config_options()` notes the key drift.

## Testing

`cargo test -p buzz-acp --lib`: 599 passed, 0 failed. The new test fails
on main and passes with this change.

Verified against the real adapter: a stdio JSON-RPC probe of the bundled
`claude-agent-acp` 0.61.0 confirms `session/new` returns `id`-keyed
config options with `opus[1m]` present as a value, and the SDK's
`SetSessionConfigOptionRequest` schema accepts `{sessionId, configId,
value}` as sent by `session_set_config_option()`.

Will PflegerandGitHub f2fe3b63c2 feat(acp): title agent sessions from the agent and channel name (#3028)
ACP harnesses that name a session from the first text they receive all
land in the same place: every managed Buzz agent opens with the
identical `[Base] You are operating inside the Buzz platform…` framing,
so the harness session list shows a wall of indistinguishable rows.
Because sessions are keyed per channel, one agent active in several
channels produces several of them.

This sends the name out of band instead. `session/new` carries
`_meta.sessionTitle` with `Agent · #channel`, composed from the agent's
`display_name` (or its unique `name` handle) and the channel it is
serving. The prompt is untouched — no tokens spent, no perturbation of
the prompt contract, and nothing new for the desktop observer's section
parsing to handle.

The mechanism is harness-agnostic: Buzz sends the field on every ACP
`session/new` regardless of which harness is behind it, and adapters
that don't read it ignore it per spec.

## Inert until a consuming adapter ships

ACP adapters ignore `_meta` members they do not recognize, so against an
adapter with no reader a Buzz session gets no title and nothing else
changes. Three adapter halves consume it — Codex, Goose, and Claude Code
(linked below); this half and each reader are only useful together, and
each reader lands independently.

No version floor is added. `codex_adapter_is_outdated_with_path` already
gates codex-acp on major version `>= 1`
(`desktop/src-tauri/src/managed_agents/discovery.rs:1276-1284`) and this
feature needs nothing above that — an older adapter is not broken by the
extra member, it simply ignores it.

## What changes

**`crates/buzz-acp`** owns sanitization and composition.
`sanitize_session_title` collapses whitespace, drops control characters,
and caps at `SESSION_TITLE_MAX_CHARS` (80) by character, not byte, so a
multi-byte character cannot be split. `compose_session_title` truncates
only the channel part against that cap, so the agent name always
survives; when the agent name alone fills the cap the channel is dropped
rather than the name. `session_new_full` sets `_meta.sessionTitle` when
a title exists and omits `_meta` entirely when it does not, since an
adapter may distinguish an absent member from a null one.

**`desktop/src-tauri`** only resolves and exports.
`resolve_session_title` picks `display_name` or falls back to `name`,
and `spawn_agent_child` writes it to `BUZZ_ACP_SESSION_TITLE` — or
removes the variable when neither candidate yields anything printable.

DMs, unresolved channels, and heartbeat sessions get the bare agent name
with no channel suffix.

## Four properties that are easy to remove by accident

**Control characters are stripped at the desktop boundary, not in the
harness.** An interior NUL cannot cross the environment boundary at all
— `Command::env` fails the entire spawn rather than passing it through.
Deferring the strip to `buzz-acp` would let a corrupted display name
turn display chrome into a spawn failure. A display name that is *only*
control characters falls back to `name`.

**The title is hashed into `spawn_config_hash`.** Without it, renaming
an agent left the running process with a stale title and no restart
badge. The hash runs the same `resolve_session_title` the spawn writes,
and skips it when a user env override shadows `BUZZ_ACP_SESSION_TITLE` —
spawn writes the title *before* the layered user env, so the override is
what actually runs, and it already reaches the hash through
`descriptor.env`. Hashing the record-derived value under an override
would badge a rename that changes nothing.

**One channel resolve serves both consumers.**
`resolve_new_session_channel_context` returns `(is_dm, title_channel)`
from a single metadata lookup, feeding both the canvas block's DM check
and the title. `ChannelInfoResolver` caches only `Some`, so two
independent calls against an unresolvable channel pay the full
`fetch_channel_info` retry sequence twice — two timeouts plus a retry
delay each — directly in front of `session/new`, precisely when the
relay is already degraded.

**The `"unknown"` channel name is treated as absent.**
`fetch_channel_info` substitutes the literal `"unknown"` for a metadata
event with no `name` tag. Composing that sentinel would title every
unnamed channel `Agent · #unknown`, reintroducing the exact collision
the suffix exists to remove while naming a channel something it isn't.
The startup cache already refuses `channel_type == "unknown"` for the
same reason.

Closes #2334

18eef633d8 feat(git): use agent display name as git author name (#3040)
Agent commits were authored by a raw 63-character npub, which makes `git
log`, `git blame`, and GitHub's author column effectively unreadable.
This uses the agent's display name for `user.name` instead, while
leaving the pubkey where it does real work.

## What changes

`build_git_env` in `crates/buzz-dev-mcp/src/shim.rs` now reads
`BUZZ_ACP_DISPLAY_NAME`, sanitizes it, and uses the result as
`user.name`. When the variable is absent or unusable it falls back to
`info.npub` — byte-identical to today's behavior.

`user.email`, `user.signingkey`, and the whole credential/signing block
are untouched. The pubkey is what NIP-98 auth, NIP-GS signing, and
contributor matching key on, and it stays in the email verbatim.

`crates/buzz-acp/src/lib.rs` forwards the variable into the dev-mcp
server's declared env, mirroring the existing `BUZZ_AUTH_TAG` block. It
reads `std::env::var` directly rather than going through `Config`, so
the variable is picked up whenever the process has it.
`crates/buzz-agent/src/mcp.rs` adds one `PASSTHROUGH_ENV` entry so ACP
clients that spawn `buzz-agent` without declaring the variable on the
wire still propagate it.

## Why a dedicated variable

`BUZZ_ACP_DISPLAY_NAME` is its own contract rather than a reuse of the
ACP session title. Commits outlive sessions: a session title is
per-session UI chrome and may be composed downstream into `Agent ·
#channel`, and if that composed form ever reached the env var, git
attribution would change silently with no test able to catch it. Git
identity gets a variable whose contract is "bare agent display name,
never channel-qualified."

Nothing writes it yet — a one-line Desktop write lands as a follow-up.
Until then `std::env::var` returns `Err`, the npub fallback fires, and
behavior is byte-for-byte current `main`.

## Sanitizing

Strip control characters, Unicode format characters, and angle brackets;
collapse whitespace runs, trim, cap at 80 characters (by `chars()`, so a
multi-byte name is never split mid-UTF-8).

Angle brackets go because git drops them silently rather than erroring:
`Duncan <evil@x.com>` renders as `Duncan evil@x.com <hex@relay>`. It
forges nothing, but it reads as though it might.

The empty result also has to cover more than literal emptiness. git's
`ident.c` treats a set of characters as "crud" — stripped from both
ends, and fatal when a name is *nothing but* those characters:

```
$ git -c user.name=';;' commit -m t
fatal: name consists only of disallowed characters: ;;
```

Verified against git 2.54.0 by committing with each ASCII byte 32..=126
as the entire `user.name`: exactly space, `"`, `'`, `,`, `:`, `;`, `<`,
`>`, `\` abort, plus all control characters (the predicate is `c <=
32`). `.` is not crud in this version, despite older lore. Names that
merely *contain* crud are fine — `O'Brien` and `Smith, Jr.` both commit
cleanly — so the check is "at least one non-crud character survives,"
not "no crud present." Without it, a display name of `;;` or `""` would
abort every commit that agent makes.

## Unicode format characters

`char::is_control` covers only category `Cc`. Category `Cf` — zero-width
spaces and joiners, bidi embedding and override marks, invisible math
operators, tag characters — is neither control, nor whitespace, nor git
crud, so those characters survived every one of the checks above. A
display name of nothing but U+200B ZERO WIDTH SPACE therefore satisfied
"at least one non-crud character survives" and git accepted the commit
with a visually blank author:

```
# pre-fix, BUZZ_ACP_DISPLAY_NAME set to two U+200B
$ git log -1 --format='%an' | xxd -p
e2808be2808b0a
```

Embedded marks were the other half: a trailing U+202E RIGHT-TO-LEFT
OVERRIDE reorders everything after it, so a stored author line renders
as something other than what it stores — the same confusion class the
angle-bracket filtering exists to prevent.

`is_unicode_format` rejects the whole `Cf` category rather than the
known-bad marks, because the boundary that matters is "invisible or
reorders text", not "the codepoint someone thought of". The 21 ranges
come from the UCD's `DerivedGeneralCategory.txt` (17.0.0), cross-checked
against Python's `unicodedata` (16.0.0); both yield exactly the same
set. They are inlined as a `matches!` rather than pulling in a
Unicode-tables crate for one predicate, and a test asserts both
endpoints of every range plus the codepoints immediately outside them —
including U+2065, which sits inside the U+2060 block but is unassigned
rather than `Cf`.

Filtering happens inside the existing per-word filter, so a format-only
name collapses to empty and falls out through the same `None` → npub
path as a crud-only name. No new fallback logic. And because filtering
precedes truncation, invisible padding cannot eat the 80-character
budget.

## NUL is handled one layer up

An interior NUL is a sibling constraint that cannot be fixed here: it
makes `Command::env` fail the entire spawn before this code runs, so it
has to die at the writer. #3028 establishes that pattern for the session
title in `resolve_session_title` via `filter(|c| !c.is_control())`, and
the Desktop follow-up that writes `BUZZ_ACP_DISPLAY_NAME` inherits it.
The shim sanitizer is a second line of defense for values that arrive
from somewhere other than Desktop.

## Verified end to end

Driving the real `buzz-dev-mcp` binary over stdio MCP and committing
inside its shimmed environment:

```
# BUZZ_ACP_DISPLAY_NAME="Duncan Idaho"
Duncan Idaho <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME unset
npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME=";;"  (crud-only; would otherwise be fatal)
npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME=U+200B U+200B  (format-only; would otherwise be blank)
npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME="Duncan" + U+202E  (bidi override stripped)
Duncan <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0

# BUZZ_ACP_DISPLAY_NAME="Dun" + U+200B + "can"  (zero-width removed, word not split)
Duncan <dcfd242e...0f95@buzz.block.builderlab.xyz>
verify_exit=0
```

Signature verification passes in every case — the signing identity is
unchanged.

`Related: #3028` — it establishes the Desktop-side env plumbing this
builds beside; the one-line Desktop follow-up that writes
`BUZZ_ACP_DISPLAY_NAME` alongside the session title ships after it
merges. Not a dependency: with the variable absent, `std::env::var`
returns `Err` and the npub fallback keeps current behavior exactly.

95fdf97880 feat(acp): bring your own harness (BYOH) — generic ACP runtime seam + settings gallery (#2773)
## What

Implements a "bring your own harness" (BYOH) generic ACP mechanism —
replacing per-harness backend code with a data-driven 3-tier system:

- **Tier 1 (compiled-in builtins):** goose, claude, codex, buzz-agent —
unchanged behavior
- **Tier 2 (bundled presets):** cursor, omp, grok, opencode, kimi, amp,
hermes, openclaw, and any future additions — defined in
`PRESET_HARNESSES`, no code duplication, icons stay
TerminalSquare/bundled-asset-only
- **Tier 3 (user-defined custom):** JSON definitions saved to
`custom_harnesses/` under app data; managed via Settings → Agents UI

## Changes

### Core data model
- `HarnessDefinition` — id, label, command, args, env, install URL/hint
- `PRESET_HARNESSES` static table — single source of truth for all
presets; `preset_harness_ids()` derives reserved IDs (D-11: no
hand-maintained copy)
- `source: "builtin" | "preset" | "custom"` tagging on every catalog
entry

### Persistence (B-4, B-6)
- `save_custom_harness_to_dir(dir, definition, rename_old_id)` —
backup-swap atomic write (backs up target → .bak, commits temp → target,
restores .bak on failure, removes .bak on success); safe on Windows
where `fs::rename` over an existing file is "access denied"
- `save_and_warm` / `delete_and_warm` — hold `PERSIST_MUTEX` for the
write + registry-warm pair, eliminating the lost-update race (B-6) where
two concurrent saves could interleave their warm calls and leave a stale
registry snapshot
- Validate-before-mutate: both IDs and env validated before any
filesystem mutation

### Env validation boundary (B-3)
- `validate_harness_definition_pub` calls `validate_user_env_keys` on
definition env at save AND load
- Rejects malformed keys (BUZZ_AUTH_TAG=x forgery shape), reserved keys
(BUZZ_MANAGED_AGENT etc.), NUL bytes, oversized values

### TypeScript boundary (B-2 / Thufir CRITICAL)
- `RawAcpRuntimeCatalogEntry` now declares `definition_env?:
Record<string,string>` and `source: "builtin" | "preset" | "custom"`
- `fromRawAcpRuntimeCatalogEntry` maps `definition_env → definitionEnv`
(camelCase); absent field defaults to `{}`
- Edit form reads `entry.definitionEnv` — env no longer erased on
save-then-edit cycle

### Unified descriptor (Phase A / Thufir F4)
- `EffectiveHarnessDescriptor { command, args, env }` in `readiness.rs`
- `resolve_effective_harness_descriptor()` — single resolver used by
spawn, spawn_hash, summary, get_agent_models (both saved and unsaved),
and readiness
- No competing arg-resolution forms

### Other fixes
- B-5: stop freezing `runtime.defaultArgs` into `record.agent_args` on
normal create paths
- B-7: readiness exec-check — `MissingBinary` variant for custom
commands not found on PATH
- B-8: onboarding transition — `setTimeout(0)` removed, parent-owned
route intent via `navigateAfterComplete` prop
- C-9: collector-discriminating sweep tests with injectable filters
- C-10: `HarnessManagementCard` uses `harnessGalleryLogic` helpers
(killed duplicate filter/sort)
- D-11: `BUILTIN_IDS` derived from `PRESET_HARNESSES` (no
hand-maintained copy)
- D-12: `mobile/pubspec.lock` churn reverted
- D-13: false ownership fast-path comment fixed
- D-14: URL scheme validation for `installInstructionsUrl`
- D-15: OpenClaw Gateway env-locus README line

### Tests added
**B-4 persistence (6 tests):**
`save_to_dir_create_writes_file_and_loads_back`,
`save_to_dir_same_id_edit_replaces_content`,
`save_to_dir_backup_is_cleaned_up_after_same_id_edit`,
`save_to_dir_rename_removes_old_file_and_creates_new`,
`save_to_dir_rename_nonexistent_old_id_is_non_fatal`,
`save_to_dir_roundtrip_with_env_preserves_values`

**B-3 env validation (6 tests):**
`validate_rejects_malformed_key_with_equals_sign`,
`validate_rejects_reserved_key_buzz_managed_agent`,
`validate_rejects_reserved_key_case_insensitive`,
`validate_rejects_nul_byte_in_value`,
`validate_rejects_value_over_per_value_size_limit`,
`validate_accepts_well_formed_env`

**B-2 API boundary (4 TS tests in tauri.test.mjs):**
`fromRawAcpRuntimeCatalogEntry maps definition_env to definitionEnv`,
`defaults definitionEnv to {} when absent`, `preserves source preset`,
`env round-trips through edit payload shape`

## Preset catalog

| ID | Label | Command |
|----|-------|---------|
| `cursor` | Cursor | `cursor-agent acp` |
| `omp` | Oh My Pi | `omp acp` |
| `grok` | Grok Build | `grok agent --always-approve stdio` |
| `opencode` | OpenCode | `opencode acp` |
| `kimi` | Kimi Code | `kimi acp` |
| `amp` | Amp | `amp-acp` |
| `hermes` | Hermes Agent | `hermes-acp` |
| `openclaw` | OpenClaw | `openclaw acp` |

## Review-fix pass (2026-07-26, Eva)

Fixes from the three-way review (Wren / Dawn / Eva) in the
buzz-generic-acp-harnesses thread, pushed as new commits (no rewrite):

1. **installHint edit round-trip** — form seeding extracted to
`formValuesFromCatalogEntry` (single source of truth), input rendered,
full-definition lossless round-trip regression.
2. **Dangling-delete coherence** — delete allowed; confirm counts
referencing agents (direct pin + persona-inherited); summary rows render
`harness (deleted): <id>`; spawn errors become actionable sentences
(`user_facing_harness_error`); composed delete→summary→start test.
3. **Comma-in-args** — rejected at `validate_harness_definition` (shared
by save AND disk load), mirrored inline in the form.
4. **Registry publish race** — collision/dup filtering moved into
`load_custom_harnesses` (both loaders inherit shadowing rules);
discovery publishes by re-reading the dir under `persist_mutex` (lock
scoped to publish only); deterministic interleaving regressions for
save-during-discovery and delete-during-discovery.
5. **Mechanical** — discarded `belongs_to_us` sweep arg deleted,
`load_global_agent_config` hoisted out of the per-record summary loop,
duplicated doc paragraph + stray SAFETY comment removed.
6. **PGID test de-flaked** — leader kept alive through the assertion.

Known follow-up (filed in review, not blocking): file-size split-outs
queued in `check-file-sizes.mjs` entries.

## Gate table — head `bf53f1d60`

| Gate | Result |
|------|--------|
| `cargo test --lib` (desktop/src-tauri) | **1701 passed**, 0 failed, 14

0a9c26ee8c fix(acp): dead-letter auth errors immediately with re-auth hint (#2751)
## Problem

Auth-class errors (expired OAuth token, HTTP 401) are non-retryable: the
token won't self-repair between attempts. Today, `PromptOutcome::Error`
for an application-class error falls into the generic `queue.requeue()`
path, burning up to 10 retry slots over a long backoff window before
dead-lettering. Will's canary run observed the 401 message being retried
repeatedly.

## Solution

Add `is_auth_error()` that classifies `AcpError::AgentError` messages
matching two narrow patterns observed in the field:

- `"Re-authenticate"` — emitted by the Claude CLI for expired OAuth
tokens
- `"API Error: 401"` — present in Claude/Codex HTTP-401 responses

Conservative matching is intentional: a false positive (misclassifying a
transient error as non-retryable) silently drops a user message, which
is worse than a false negative (extra retries on an auth error).

In `handle_prompt_result`, a new branch intercepts the failing batch
before `queue.requeue()` for auth-class errors and dead-letters
immediately, posting a user-visible notice to re-authenticate the CLI
(e.g. `claude /login` or `codex login`).

The transport/application split in `PromptOutcome::Error` is untouched —
this only changes batch fate after an application-class auth error.

## Tests

6 new tests in `error_outcome_emission_tests`:
1. `is_auth_error` matches `Re-authenticate` message
2. `is_auth_error` matches `API Error: 401` message
3. `is_auth_error` rejects other `AgentError` messages (usage credits,
etc.)
4. `is_auth_error` rejects transport errors (I/O, WriteTimeout)
5. Auth error dead-letters immediately — 0 pending channels after
`handle_prompt_result`
6. Non-auth application error still requeued — 1 pending channel after
`handle_prompt_result`

Full `cargo test -p buzz-acp`: 598/598 passing.
