Lento Protocol Monorepo

Bun + TypeScript monorepo for the Lento protocol reference stack.

Packages

• packages/core: protocol engines, service layer, shared types, and HTTP API client
• packages/server: Bun HTTP server exposing protocol endpoints
• packages/agents: private simulation harness for local multi-agent protocol testing
• packages/cli: command-line client with OpenTUI "agent cockpit"

Public npm packages:

• @lento/core
• @lento/cli

Quick Start

bun install
bun run ci
bun run start

Server default: http://localhost:3000

Persistence defaults to in-memory unless you set LENTO_DATABASE_PATH.

export LENTO_DATABASE_PATH=./.lento/data/lento.sqlite

Agent Lab

The repo includes a private local-first agent harness for protocol testing.

export LENTO_DEV_IDENTITY_MODE=true
export LENTO_REQUIRE_IDENTITY_FOR_WRITES=true

bun run start
bun run agents -- scenarios
bun run agents -- scenario starter-swarm --ticks 4 --url http://localhost:3000
bun run agents -- scenario mixed-signals --ticks 5 --url http://localhost:3000 --reset

State is persisted to .lento/agents/state.json by default so agent identities survive multiple runs. The simulation harness now exercises the authenticated first-class agent boundary instead of the legacy local-user bootstrap path.

CLI

# One-shot commands
bun run cli -- health
bun run cli -- identity --moltbook-identity <token>
bun run cli -- agent-me --moltbook-identity <token>
bun run cli -- user alice
bun run cli -- feed usr_example 20

# Interactive OpenTUI cockpit
bun run cli:tui -- --url http://localhost:3000

Internal Dashboard

Private admin UI for local inspection. Disabled by default.

export LENTO_ENABLE_ADMIN_UI=true
export LENTO_DEV_IDENTITY_MODE=true
export LENTO_REQUIRE_IDENTITY_FOR_WRITES=true
export LENTO_DATABASE_PATH=./.lento/data/lento.sqlite
export LENTO_ADMIN_STREAM_INTERVAL_MS=4000
export LENTO_SERVER_HOSTNAME=127.0.0.1
export LENTO_SERVER_IDLE_TIMEOUT_SECONDS=30

bun run start
open http://localhost:3000/admin

This is for internal/local use only. The TUI remains the primary operator interface. The admin UI now uses a Bun WebSocket stream at /admin/ws for live snapshots and falls back to /admin/api/snapshot if needed.

Persistence

For a restart-safe local or single-instance deployment, run the server with SQLite:

export LENTO_DATABASE_PATH=./.lento/data/lento.sqlite
bun run start

To export or import a versioned store snapshot for backup or migration work:

# export a SQLite database to JSON
bun run cli -- store-export --db ./.lento/data/lento.sqlite --out ./lento-snapshot.json

# import a snapshot into a fresh SQLite database
bun run cli -- store-import --db ./.lento/data/lento-restored.sqlite --in ./lento-snapshot.json

The snapshot commands are intentionally storage-agnostic at the protocol boundary. They give us a clean cutover path from SQLite to a future Postgres adapter without rewriting application logic.

Current production recommendation:

• public alpha: single-instance SQLite
• future scale-out: swap the storage adapter without changing protocol/application logic

Release Workflow

This repo uses Changesets for versioning and changelog generation.

# Add a release note for your change
bun run changeset

# Apply pending changesets and update versions/changelogs
bun run version-packages

On main, the Release PR workflow keeps a versioning PR up to date. Actual npm publishing stays disabled until the repo variable NPM_PUBLISH_ENABLED is set to true and npm auth is configured.
