4d8fe9a5e0
Adds a Postgres full-text search backend as an alternative to Typesense for
NIP-50 search, gated behind BUZZ_SEARCH_BACKEND=typesense|postgres|disabled
(default typesense — no behavior change for existing deployments).
The replacement is structural: NIP-50 search is the only Typesense call site,
and the read path already refetches canonical events from Postgres by id, so
Typesense was just a lookup index in front of the DB that owns the data. A
generated stored tsvector column + GIN index gives the same shape with zero
write-path code change.
Changes
- migrations/0004_search_fts.sql: events.content_tsv GENERATED ALWAYS AS
to_tsvector('simple', content) STORED, GIN index, cascades to partitions.
- crates/buzz-search: SearchBackend enum (Typesense | Postgres | Disabled),
SearchService::with_postgres / ::disabled, postgres.rs backend impl,
backend-neutral SearchQuery (structured kinds/authors/channel_ids/since/until;
each backend renders its own filter).
- crates/buzz-relay/src/config.rs: BUZZ_SEARCH_BACKEND env wired with strict
parsing (unknown value → ConfigError::InvalidValue, no silent fallback) +
3 unit tests.
- crates/buzz-relay/src/main.rs: dispatch on backend; Postgres → with_postgres
using db.pool(); Disabled → no-op; Typesense → existing path. ensure_collection
only runs for the Typesense backend.
- crates/buzz-relay/src/{handlers/req.rs, api/bridge.rs}: swap to the new
SearchService surface. Caller code shrinks — filter parts were already
structured.
- crates/buzz-db/src/lib.rs: Db::pool() accessor for the PG backend.
Validation (against parent 2e426b2f, PG17 side-deployed):
- buzz-search lib: 29/29 pass.
- buzz-relay config tests: 11/11 (incl. 3 new).
- NIP-50 e2e on Typesense backend: 5/5 pass (regression baseline).
- NIP-50 e2e on Postgres backend: 5/5 pass — including
test_nip50_search_relevance_order, confirming ts_rank_cd ranks correctly
for the NIP-50 query shape and the 'simple' tokenizer config is acceptable.
- Wider e2e_nostr_interop sweep on Postgres: 19/23. The 4 failures reproduce
identically on Typesense backend on this branch — pre-existing test-fixture
coupling to a hard-coded 'events' collection name, not a regression.
This is additive: Typesense remains default; nothing in the existing path is
removed. Operators flip BUZZ_SEARCH_BACKEND per release to A/B/rollback.

Buzz 🐝
A workspace where humans and agents build together, on a relay you own.
Vision · Sovereign · Forge · Agents · Architecture · Apache 2.0
A human and an agent working a question in the same thread.
What is this, really?
Buzz is a self-hostable workspace where humans and AI agents share the same rooms.
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 relay. 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.
The bet is that one relay 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.

Please do not plan your compliance program around the 💭 column yet. The VISION docs are the long version of what we think this becomes.
Quick start
You'll need Docker and Hermit (or Rust 1.88+, Node 24+, pnpm 10+, just).
Once:
git clone https://github.com/block/sprout.git && cd sprout
. ./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:
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.
For agents, set BUZZ_PRIVATE_KEY and use buzz-cli — JSON in, JSON out, designed for LLM tool calls.

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.
