## Summary Re-applying `schema/schema.sql` to a database that `pgschema apply` and `scripts/reconcile-schema-after-pgschema.sql` already bootstrapped fails with `cannot drop inherited constraint "events_p2026_01_pkey" of relation "events_p2026_01" (SQLSTATE 42P16)`. Because of that, `scripts/start-relay-for-tests.sh` breaks against a reused database. **Cause:** pgschema 1.7.4 moves a partitioned table's partition key to the front of its primary key when it creates the table. A pgschema-bootstrapped `events` therefore gets `PRIMARY KEY (created_at, community_id, id)`. `schema/tables/public/events.sql` and `migrations/0001` both declare `(community_id, created_at, id)`. Every later plan drops and re-adds `events_pkey` and each declared child's key. This happens even on a database that was never reconciled. The plan only becomes unexecutable after the reconcile script attaches the children, because their keys are then inherited. As a side effect, pgschema-bootstrapped databases also had a differently ordered PK index than migration-managed ones. **Fix:** after the partition ATTACH block, the reconcile script now compares `events_pkey` with the declared `PRIMARY KEY (community_id, created_at, id)`. If they differ, it rebuilds the key on the parent. It then asserts that `events` and every partition carry the declared key, which is the "convergence plus live assertion" shape `docs/database.md` requires. PostgreSQL recreates each partition's key with the same `<child>_pkey` names, so a reconciled re-apply now plans nothing. The block does nothing when the key is already correct. `migrations/0001` is untouched. Only pgschema-bootstrapped dev and test databases run this script, so it does not touch the out-of-band partitioned-table procedure. `delivery_log` is not affected. Its key `(delivered_at, id)` already starts with the partition key. **Existing local databases:** a database reconciled before this change would still fail its next `pgschema apply`, because the reconcile script only runs after apply. The repair therefore also lives in `scripts/repair-events-pkey.sql`. That file does nothing when `events` doesn't exist yet, and `scripts/start-relay-for-tests.sh` runs it before apply; it's the only launcher that reuses its database. The reconcile script keeps a verbatim copy for fresh bootstraps, and a unit test keeps the two identical. The rebuild drops the key with `IF EXISTS`, so a database that has lost its key still converges. It also takes its locks with a 10s `lock_timeout`. If a relay still holds `events`, it fails with "Stop any relay using this database, then rerun" instead of hanging. `start-relay-for-tests.sh` now builds the relay's `DATABASE_URL` from the `PG*` variables it already exports. The secret scanner flags the literal URI once the file is touched. The value is unchanged. pgschema 1.13.3 keeps the declared order and creates children as native `PARTITION OF`. Upgrading would make this block and the ATTACH blocks unnecessary, but it changes behavior for every caller, so it is left for a separate change. ### Related issue Follow-up to block/buzz#8487, which added the probe test and `.pgschemaignore`. Now rebased onto `main` after that PR merged. ### Testing - `pgschema_reapply_keeps_runtime_partitions` now asserts the plan after the maintenance pass is **empty**, which replaces the `DROP TABLE` and per-monthly plan checks. It then applies and reconciles a second time. Without the new block it fails with `ALTER TABLE events DROP CONSTRAINT events_pkey; ...`. With the block it passes. - It also includes the optional notes from the #8487 review: - After maintenance, it checks that both catch-alls are still present and attached, not only that the zipped bounds differ. - The first runtime monthly comes from the declared catch-all's lower bound instead of a hard-coded `p2026_07`. - The doc comment now states only what the test pins: bounds are not compared, and the plan is empty. - I broke the rebuild on purpose by re-adding the key in the wrong order. The new assertion fails the reconcile script with `events and its partitions must have PRIMARY KEY (community_id, created_at, id)`. - CLI runs against local Postgres 17: - Fresh DB: apply → reconcile → apply → reconcile → plan. The second apply reports no changes and the plan is empty. - DB reconciled with the old script: the next apply fails with SQLSTATE 42P16. After running the new reconcile script once, apply reports no changes and the plan is empty. - `events_pkey_repair_runs_before_reused_apply_and_matches_reconcile` checks two things: the reconcile script carries the repair block verbatim, and `start-relay-for-tests.sh` runs the repair before `pgschema apply`. It fails if the two copies drift. - I ran the repair script and then the bootstrap against four local probe databases: one reconciled with main's script, an empty one, one applied but never reconciled, and one with no `events` key. All four end with an empty plan. With another session holding a lock on `events`, the repair fails after 10s with the hint and leaves the key untouched. It succeeds once the lock is released. - `admin_schema_parity_between_desired_state_and_migrations` and the `runtime::migration` unit tests pass. fmt and clippy are clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
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.
