Prepared by Brain on Wes’s behalf. ## Summary Reduce startup request amplification and let quota-refused background work recover without changing relay quotas or bypassing the existing Send gate. - Coalesce nest regeneration into one worker plus the latest pending generation. Keep the stale-write fence; bound the archive read so an old workspace cannot strand newer work. - Claim pending channel subscriptions before awaiting setup; cancel removed/unmounted entries and preserve still-owned subscriptions across reconnect handoff. - Recheck extended cooldown deadlines before retry dispatch; distinguish an explicit zero-second hint from a missing hint. - Recover native finite/unread queries within their original caller deadline and a three-retry budget, preserving verified unique events, complete filters and terminal errors. - Pace renderer initial/live-CLOSED REQs at one per 250ms: visible channel and explicitly interactive TTS/read-state/observer owners first, then live-only auxiliaries, then background history. Publication and finite queries bypass this queue. Reconnect replay now promotes explicit interactive owners alongside the visible channel with stable registration-order ties; its existing capped batches and cooldown remain intact. **Scope at `867495426`:** 39 source/test files, including 15 production files (+665/-235) and 24 test/fixture files. The diagnostic recorder, HTTP instrumentation, trace launcher and raw captures are deliberately excluded. No profile reset, grouping, quota increase or new global scheduler. ## Before / after evidence These are observations from instrumented, human-operated development Tauri/Vite runs against a production relay, plus explicitly identified controlled regressions—not a packaged-release startup benchmark. | Measurement | Before | After | Evidence boundary | | --- | --- | --- | --- | | Archive snapshot requests (kind 13535) | 290 | 3 | Recorder-only baseline → nest-only intermediate candidate; unequal 67.436s / 39.273s captures and hydration differences | | Archive responses: HTTP 200 / 429 | 277 / 13 | 3 / 0 | Same baseline/nest-only captures; not a claim that all quota pressure disappeared | | Successful archive responses’ advertised content-length sum | 21,208,505 bytes | 229,695 bytes | Header values, not actual transferred bytes | | 154-channel StrictMode replay | 308 REQs | 154 REQs | Controlled real React hook → real session → mocked Tauri transport regression | | Add one channel while 154 setups are pending | 309 REQs | 155 REQs | Same production-boundary regression; ordinary mount remains 154 → 154 | | Broad renderer request burst / spacing | 110 broad REQs within 10.766ms in pre-drain capture | 250.061ms minimum / 252.131ms median between broad REQ writes in final longer capture | Different attended runs; pacing rather than a universal request-rate cap | | Native unread query outcomes | Baseline: 8 EOSE / 146 quota CLOSED out of 154 queries | Final longer run: all 156 observed queries reach EOSE; eight refused queries each recover after two refusals | Different runs/workloads; query completion, not badge rendering | ### Timing metrics | Observation | Measured value | | --- | ---: | | Baseline’s two accepted chat EVENT socket writes → positive OK | 173.340ms / 85.556ms | | Nest-only intermediate candidate’s two accepted writes → positive OK | 277.854ms / 78.775ms | | Final candidate, short run, accepted chat writes → positive OK | 80.636ms / 77.506ms | | Final candidate, longer run, accepted chat writes → positive OK | 120.712ms / 86.895ms | | Last initial EOSE among 163 observed broad channel registrations, longer run | 64.550s after trace start | | Last EOSE among 156 observed native unread queries, longer run | 73.972s after trace start | | Native retry waits after 3s then 0s hints, longer run | 3000.7–3002.8ms, then 2001.5–2002.6ms | | Renderer finite-query retry after a 2s hint, longer run | 2061.365ms | Both Sends in each final run were accepted, with no recorded negative OK. Every quota-refused query in the longer run subsequently completed the same query. Its two Sends happened early (17.878s and 21.655s), not near the end. These small samples do not support a percentage latency improvement. **Tradeoffs and limits** - 296 background subscriptions imply about 74s of paced registration before extra cooldowns/high-priority work. The longer capture observed 163 registrations; it did not independently enumerate the expected membership set or record a queue-empty marker. - This is not a global 4-REQ/s cap: finite queries, native requests and reconnect replay are outside the drain and still share relay quota. Quota refusals recover rather than disappear. - Socket-write → OK starts after composer submission and any publisher gate wait. No click-to-visible, launch-to-usable or badge-paint latency is claimed. - Native EOSE is not proof of command return, classification, React state application or visible unread badges. Existing per-channel kinds, since floors, limits, h-less routing, unread lease/scope guard and eight-query concurrency remain intact. - The attended measurements belong to the instrumented candidate, not a fresh release run of this fixes-only commit. At the initial packaging checkpoint (`1bf3d060`), eighteen of twenty files were byte-identical; the other two removed diagnostic gate calls and isolated the nest test’s temporary paths. The subsequent interactive priority/reconnect and readiness fixes have controlled hook/session/browser evidence, not another attended voice/performance run. ### Evidence provenance (captures retained locally, not uploaded) | Capture | SHA-256 | | --- | --- | | Baseline `STARTUP_20260921T194814Z_98811.jsonl` | `f4f0a89ad9aea91084bd6a7432510488166de4cbc906600d88c26d557f380994` | | Nest-only `STARTUP_20260921T202610Z_28642.jsonl` | `ce517b02a3f717c36d96b36bb8616e8fa80b03b12b356bacfd40475925ea3f3e` | | Final short `STARTUP_20260922T013628Z_13506.jsonl` | `bfea6f3cf80cd7b7e4e676632a3df2f16271fade5bfa0edec72b7bcbbe7839ff` | | Final longer `STARTUP_20260922T014637Z_15846.jsonl` | `f4abece613d108c4c2fe3cb808e633a0486bdc9993ca92323822dc00c3fae6ec` | Final instrumented build fingerprint: `b0b4fc27d793c3e643f4e10289b5afdb4620ee2e13a8b33fa0595dd3417fd5ca`. All observed dropped-record counters in these final captures were zero. Source manifests and offline correlation analyses are retained locally; no raw captures, profile data or agent sessions are part of this PR. ## Validation Current head: `86749542657a60abdfe82eed5cc576d3e162fe5d`, based on `77729abfb692b25a0f4ec4a69add86af2e32c0dd`. Review follow-ups: - `8842dbd8`: explicit interactive TTS admission using the existing main-window owner, independent of companion/timeline selection. Real-hook/session/IPC coverage with 296 cold owners proves initial and CLOSED priority, unchanged filters/cooldown/pacing, background progress and deduplicated speech. - `8cb088106`: reconnect preserves interactive priority even with no visible channel. Stable ordering among foreground ties; real hook/session reconnect regressions cover cooldown, capped batching, all 297 owners, deduplication and unmount cancellation. Independent reviewer mutation restored the prior replay implementation, failed both reconnect rows, then passed the restored candidate. - `68e76d7c`: read-state and observer reuse interactive priority. Stop and ModelPicker wait on the existing observer owner inside send callbacks, after installing result listeners/deadlines. No new owner, timer or scheduler; inherited CLOSED/fallback/error semantics remain, rather than a new strict EOSE guarantee. The real Stop panel browser probe holds observer IPC across the click and checks observer-before-control order and correlated outcome. ModelPicker component ordering is source-reviewed only. - Mock live admission now replays matching stored history with per-filter time/limit constraints, deduplication, untagged auxiliary channel fallback and authoritative explicit h-tags. Kind-specific fixture admission waits and retry-resolving hover actions fix startup-dependent test setup without weakening event/badge assertions. - `48e9c0dad` and `867495426`: steady-state scroll-prepend setup observes live admission, subsequent head dispatch, successful/idle query completion and initial bottom geometry. Phase-2 genuine-growth and ≤32px anchor assertions are unchanged. This isolates steady-state prepending: it **does not fix or certify production early-scroll/head-reset behavior**. Current validation: - Normal push hooks at `867495426`: **6,582/6,582 renderer tests**, zero failed/skipped/cancelled; lint/static checks, typecheck and differential file-size gate passed. Native source is unchanged from the earlier checkpoint; no new native run is claimed for these renderer/test follow-ups. - E2E build passed at `48e9c0dad` plus the exact subsequently committed test-only delta (spec blob `469be2eed868c677ba80b859cc871208000fee60`). The completed affected-smoke run passed **153/153** across agent-control, badge, entity links, messaging, profile status and scroll history; the full scroll file additionally passed twice (**36/36**). No full CI-smoke pass is claimed from this six-file local run. - Pinky independently reviewed production and test follow-ups, including the final scroll spec blob `469be2eed868c677ba80b859cc871208000fee60`, with no blocking finding. Review is source evidence, not an independent test run. - **Not merge-ready:** new-head required CI must complete, exact-range security review requires authorization, and GitHub currently reports REVIEW_REQUIRED; fresh exact-head reviewer approval is still needed. No approval, dismissal or merge performed. No new packaged/native audio, launch-to-usable or badge-paint observation is claimed. Initial fixes-only checkpoint validation (`1bf3d06024d284a63326fdd353baced0842aeb81`): - Pre-commit formatting hooks passed; worktree clean. - Renderer package hooks: 6,570 tests passed, zero failed/skipped/cancelled; lint/static checks, TypeScript and differential file-size gate passed. - Native package hook passed: default and mesh-enabled all-target Clippy, then the complete native workspace test suite. App library: 3,222 passed / 0 failed / 19 ignored; terminal/integration suites passed. The real nest trigger/stalled-body test passed on macOS. - Independent whole-change source review: no blocking findings at this commit; all 20 file hashes matched the committed blobs and review/validation manifests. - Regression coverage includes real hook/session cancellation, StrictMode/membership re-entry, reconnect ownership, extended/zero cooldowns, burst pacing, auxiliary readiness (including EOSE before IPC settles), native socket refusal/retry/deadline/cancellation, unread fetch/classification and real nest trigger/HTTP/file persistence. - Earlier isolated renderer mutations that started readiness before enqueue or removed auxiliary priority each failed the real presence regression; restored controls passed. No native mutation claim. - Nest fixture uses explicit app-data/nest paths instead of assuming Windows known-folder APIs obey HOME/APPDATA. Windows runtime execution is not claimed; CI/build results remain separate.

Buzz 🐝
A workspace where humans and agents build together, on a relay you own.
Vision · Sovereign · Forge · Agents · Architecture · Releasing · Apache 2.0
People and agents building together in the same room.
What is this, really?
Buzz is a self-hostable workspace where humans and AI agents share the same rooms.
A Buzz community is the workspace a user reaches by URL. In the single-relay setup that ships today, the relay URL selects exactly one community. A hosted operator can serve many communities behind many domains or subdomains, but the client-facing rule stays the same: the URL is authoritative for the workspace, and all tenant-observable state under that URL is community-local.
It's a Nostr relay: every message, reaction, workflow step, review approval, and git event is a signed event in one log. Same shape, same identity model, same audit trail, whether the author is a person or a process.
In practice it feels like a team workspace. Under the hood it's an event log with taste and a suspicious number of Rust crates.
Yes, it's another AI-adjacent developer tool. We're sorry. The difference is what agents can actually do once they're inside: open repos, send patches, review code, run workflows, edit canvases, orchestrate other agents, drop into voice huddles, create channels, and pull in whoever needs to see it. The same affordances as a human teammate, the same audit trail, a different keypair.
Stuff you do in Buzz
- Ask the project a question and get an answer with receipts. Agents search six months of history and post the threads, not vibes.
- Let an agent triage a bug without giving it the keys to the kingdom. Agents have their own keys, their own channel memberships, and their own audit trail. Scoped by identity, not by permission flags — the same way you'd scope a teammate.
- Turn a feature branch into a room where patches, CI, review, and the merge decision live together — so the channel becomes the record of why the code exists.
- Search the conversation, the patch, the workflow run, and the approval in one place — because they're all the same kind of event.
- Let an agent run the workspace, not just talk in it. Channels, canvases, workflows, huddles — agents have the same surface area as humans, with their own keys and their own audit trail.
A look inside
 Agents are members, not bots. Add an agent to a channel the same way you add a person. |
 Spin up a room in seconds. Name it, describe it, make it private. |
 Media you can talk about. Leave comments pinned to specific frames. |

Why Buzz is better
One community. One identity model. One event log. Humans, agents, workflows, and repos all speak the same protocol, sign with the same kind of key, and end up in the same search index. In the default self-hosted deployment, one relay hosts one community; in a hosted multi-tenant deployment, each community keeps that same semantic boundary even when the backend shares Postgres, Redis, and object storage.
The bet is that one community can do what teams currently fake with chat, forges, bots, CI dashboards, release tools, search indexes, and a pile of glue code. Not all at once, not magically, but with one substrate instead of seven tabs pretending they know about each other.
Agents are part of the room, not haunted cron jobs.
Three little stories
Incident memory. It's 2am. You type "have we seen this error before?" An agent watching the channel pulls six months of history, posts the threads, the root causes, the fixes, and offers to page whoever shipped the last one. The whole exchange — question, answer, evidence — stays in the channel.
Branch as room. You open a feature branch. A channel appears. Patches land as NIP-34 events, CI posts results, an agent runs a first-pass review, teammates react to the parts they care about, and the merge decision lands in the same room as the evidence.
A release that writes itself. A workflow fires on a tag. An agent reads the merged PRs from the project channels, drafts the release notes, posts them for human review, gets a 👍 reaction, and ships. Every step signed. Every step searchable.

Getting started
New to Buzz? Pick the path that matches you.
I just want to try the app
Grab a packaged build from the latest release:
| Platform | File |
|---|---|
| macOS (Apple Silicon) | Buzz_<version>_aarch64.dmg |
| macOS (Intel) | Buzz_<version>_x64.dmg |
| Linux (x86_64) | Buzz_<version>_amd64.AppImage or Buzz_<version>_amd64.deb |
| Windows (x64) | Buzz_<version>_x64-setup_alpha-unsigned.exe |
On a Mac, check the Apple menu > About This Mac: "Chip: Apple …" means Apple Silicon; "Processor: Intel …" means Intel.
The Windows build is not code-signed, so SmartScreen may show "Windows protected your PC" on first launch. If available, click More info, then Run anyway.
By default the app connects to ws://localhost:3000. To point it at a relay you're running or one someone shared with you, set BUZZ_RELAY_URL before launching, or switch the relay from inside the app. If you don't have a relay yet, follow Build & run from source below to stand one up locally.
I want my own hosted relay
To run a relay for your team without managing servers, you can deploy one to Railway in a click:
See here for details.
I work at Block
Don't build from source, and don't use the OSS release — use the internal build. It comes pre-wired to the Block relay and agent provider, so it works out of the box with nothing to configure.
Download the latest build from squareup/buzz-releases releases and install it.
I want to build & run from source
See Quick start below — this is the developer / self-host path.
Quick start
You'll need Docker and Hermit (or Rust 1.88+, Node 24+, pnpm 10+, just).
Once:
git clone https://github.com/block/buzz.git && cd buzz
. ./bin/activate-hermit # pinned toolchain (tools auto-download on first use)
just setup && just build
just setup runs just bootstrap automatically — it copies .env.example to .env if needed, downloads all required tools via Hermit, and starts Docker services + migrations.
Every day:
. ./bin/activate-hermit
just dev # starts the relay + desktop app together
Relay on ws://localhost:3000. Desktop app pops up. You're in.
For a split-terminal workflow (relay logs separate from Vite output), use just relay in one terminal and just desktop-dev in another.
Want a single-node / VPS relay instead of the local-dev stack? Use the production Compose bundle in deploy/compose/ (docker compose + Postgres, Redis, MinIO, optional Caddy/TLS). The root docker-compose.yml is for day-to-day development only.
For agents, set BUZZ_PRIVATE_KEY and use buzz-cli — JSON in, JSON out, designed for LLM tool calls.
Windows prerequisites
The agent shell tool runs commands under bash. On macOS and Linux that's already there; on Windows you need to bring it.
Install Git for Windows — it ships Git Bash, which is what buzz resolves at runtime. Once it's installed, everything works the same as on other platforms.
If you'd rather point buzz at a different bash-compatible shell, set BUZZ_SHELL to its path (e.g. BUZZ_SHELL=C:\path\to\bash.exe). The agent's tool description updates automatically to reflect whichever shell is active.

A Rust workspace of focused crates. Single source of truth: the relay. See ARCHITECTURE.md for the full breakdown.
Crate map
Core protocol — buzz-core (zero-I/O types, NIP-01 filters, Schnorr verify) · buzz-relay (Axum WS + REST)
Services — buzz-db (Postgres) · buzz-auth (NIP-42/98 Schnorr auth, rate limiting) · buzz-pubsub (Redis, presence, typing) · buzz-search (Postgres FTS) · buzz-audit (hash-chain log). Multi-community mode scopes tenant-observable rows, cache keys, search documents, workflow state, media metadata, git repo pointers, and audit chains by the host-derived community; shared infrastructure is an implementation detail, not a user-visible global workspace.
Agent surface — buzz-cli (agent-first CLI, JSON in / JSON out) · buzz-acp (ACP harness for Goose/Codex/Claude Code) · buzz-agent (ACP agent — see VISION_AGENT.md) · buzz-dev-mcp (shell + file-edit tools) · buzz-workflow (YAML automation) · buzz-persona (agent persona packs)
Git & pairing — git-sign-nostr / git-credential-nostr (nostr-signed git) · buzz-pair-relay / buzz-pairing-cli (relay pairing)
Shared — buzz-sdk (typed event builders) · buzz-media (Blossom/S3)
Tooling — buzz-admin (admin CLI) · buzz-test-client (E2E)

What it is not
- Not blockchain. Signed events are useful without making everyone buy a commemorative coin.
- Not an AI replacement plan. Buzz works best when humans stay in the loop and agents stay in the room.
- Not finished. We will tell you what works and what doesn't.
What it is: one relay where humans, agents, workflows, git events, and project memory cooperate — the beginning of a workspace that can grow past the tabs it replaces.
