## What Relay-only carve-out of the ingest half of #4999: generic EVENT ingest now accepts kind:30179 (NIP-PMA private managed-agent config). One file, `crates/buzz-relay/src/handlers/ingest.rs`, 16 insertions / 15 deletions; **two semantic lines**, byte-identical to the ingest hunk of #4999 at `6f486e88`: 1. `required_scope_for_kind`: 30179 requires `Scope::UsersWrite` — same arm as its public sibling 30177 and the other owner-authored NIP-AP kinds. 2. `is_global_only_kind`: 30179 is owner-global, keyed `(pubkey, kind, d-tag)`; a stray `h` tag must not channel-scope it. The rest is import reflow plus replacing the guard test with a positive one (`private_managed_agent_kind_is_owner_scoped_global_user_data`: asserts UsersWrite scope, global-only, no h-channel scope). ## Why the guard test can be retired The removed test (`private_managed_agent_kind_remains_rejected_until_atomic_ingest_exists`) pinned a stated precondition: *"must not enter generic EVENT ingest before privacy and aggregate CAS deploy."* Both halves are resolved: - **Privacy** — the author-only read gates for 30179 shipped to main with #4593: `AUTHOR_ONLY_KINDS` membership, `req.rs` pre-filter + result gates, `count.rs`, `event.rs` fanout, and the bridge pre-filter (`bridge.rs:999-1000` returns `restricted: author-only kinds require authors=[self]` / 403). Only the author can read the event back. - **Aggregate CAS** — #4999 settled generation as **advisory**: the `g` tag is shape-validated, never relay-enforced. Last-write-wins per coordinate is the contract of record (see the kind:30179 contract blurb in #4999), so no CAS mechanism is pending on the relay side. ## Why this is inert to existing relays and clients - No production desktop code on main authors kind:30179 — the codec (`private_managed_agent.rs`) has zero non-test callers. This PR accepts a kind nobody can produce yet. - Content is opaque NIP-44 ciphertext to the relay; the relay never decrypts it. - Reads remain author-only via the already-shipped gates above. - Storage is the standard parameterized-replaceable path already exercised by kinds 30175–30178. No schema, config, or migration changes. ## Testing - Full `buzz-relay` package suite at this commit: 859 passed, 1 failed — `api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` (504 vs 200), which **reproduces identically on clean main `769ac70b`** with this change stashed; pre-existing/environmental, not introduced here. - New positive ingest test passes. - Pre-push hooks green (branch-skew, rust-tests, desktop-tauri-checks). ## Relationship to #4999 #4999 (relay-primary agent config, desktop half) stays DO-NOT-MERGE pending live relay receipts + real CI; once this lands and deploys, its live test simplifies to plain `desktop-standalone` against the real relay, and #4999 rebases to drop its now-duplicate ingest hunk (identical bytes → trivial rebase). Originating thread: buzz://message?channel=06f13ed3-0557-4ac2-922c-1545dd00bf97&id=2a43b3b4933a2ea78b77088619251c061355f9b7b6dc29ea0d702193f2344149 ## Brownfield FTS note (review findings, operator-ruled non-blocking for this PR) Max and Sami independently identified that the FTS privacy skip-set is regime-dependent: migration 0008 installs the positive allowlist (`kind IN (0, 9, 40002, 45001, 45003)`) **only on an empty events table**; an already-populated database keeps the 0001/0005 negative skip-list (wrapped by 0014 to add 30350), which omits 30179 — so on such an installation this PR admits 30179 rows whose NIP-44 ciphertext gets indexed by `to_tsvector`. Sami measured both regimes against real Postgres (brownfield: 30179 INDEXED; fresh: NULL) and demonstrated the existing drift test only exercises the fresh regime. `schema/schema.sql:222`'s canonical literal is also the negative list and omits 30179. Migration dates put any relay deployed with data before 0008 landed (2026-07-13) in the brownfield class. **Scope of exposure (Sami's trace):** not a content leak — `event_visible_to_reader` / `is_author_only_event` gates hold on both search surfaces (`req.rs:725`, `bridge.rs:1770`), so foreign readers receive nothing. Lost is the storage-level NULL-tsv backstop plus FTS page budget burned on post-filtered hits. **Operator ruling (Tyler, events `1472e5b6`, `cbd368ed`):** ship this PR without an exclusion migration. Safety argument that makes this sound rather than merely accepted: main has **zero non-test 30179 writers** until #4999's desktop half deploys — no 30179 rows can exist, so nothing can be indexed in any regime while this PR is the only half live. **Additional review characterizations (Sami, non-blocking, on the record):** - *Behavioral delta enumerated:* routing triple (`required_scope_for_kind` / `is_global_only_kind` / `requires_h_channel_scope`) compared for all 65,536 kinds at base `769ac70b` vs head `77eeba6e` — exactly one row differs (30179). No other kind or client changes behavior. - *"SQL visibility before LIMIT" (NIP-PMA step 2):* no `AUTHOR_ONLY_KINDS` pushdown clause exists in `buzz-db` (only `SHARED_GATED_KINDS` has one). Author-only kinds are protected by the pre-filter (`author_only_filters_authorized`) plus post-filter omission; mixed-kind filters can burn candidate-page budget on discarded rows. Pre-existing and identical for 30300/30350 — not introduced here; noted so the NIP's step-2 checkbox is not read as fully ticked. - *Envelope validation gap:* 30179 is the only parameterized-replaceable kind at ingest with no per-kind envelope validator (codec grammar checks run in the desktop writer, not the relay). Generic limits only (256 KiB, ±15 min, pubkey==identity, d-tag bound). Self-inflicted footgun bounded to the author's own coordinate — candidate companion to the exclusion migration in the #4999 rebase, deliberately not added here. **Bound follow-up (required before/with the #4999 desktop half):** a 0014-shape additive migration (`pg_get_expr` capture + `CASE WHEN kind = 30179 THEN NULL ELSE (<existing>) END` wrap), add 30179 to the `schema/schema.sql:221` literal, and a brownfield-regime variant of the FTS drift test, per Sami's finding. Deploy-time spot check if ever wanted: `SELECT pg_get_expr(d.adbin, d.adrelid) FROM pg_attrdef d JOIN pg_attribute a ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE d.adrelid = 'events'::regclass AND a.attname = 'search_tsv';` Signed-off-by: Tyler Longwell <tlongwell@block.xyz> Co-authored-by: Eva <011987e296fd5006292d2f930b574be47c7801048d1983c46c425d3c95f0cffd@buzz.block.builderlab.xyz> Co-authored-by: Tyler Longwell <tlongwell@block.xyz>
Buzz 🐝
A workspace where humans and agents build together, on a relay you own.

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)

Configuration (env vars, defaults work for local dev)
All defaults work out of the box. Override via .env. Full reference in .env.example.
Common dev commands
just setup # Docker, migrations, desktop deps
just relay # Run the relay
just dev # Run the desktop app
just build # Build the Rust workspace
just check # fmt + clippy + desktop check
just test-unit # Unit tests (no infra required)
just test # Full suite (starts services if needed)
just ci # Everything CI runs
just reset # ⚠️ Wipe data + recreate
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.
