# Colibri

The Clawdie control plane core — a small, cross-platform (FreeBSD + Linux) Rust
daemon. Developed from an operator USB environment; deploys as the **Clawdie
service** on bare FreeBSD hardware (ZFS RAID1, PostgreSQL + pgvector, bhyve
VMs, Bastille jails). Unifies coordination (task board, agent registry, skills
catalog) with cache-first cost discipline (byte-stable prompt prefixes,
cache-hit metering).

**Status:** workspace gates are fmt/clippy/test/release green. Round 2 audit is closed. Current priorities: ISO boot/runtime validation, Pi spawn end-to-end, and cost-mode enforcement (see [`docs/MULTI-AGENT-HOST-PLAN.md`](docs/MULTI-AGENT-HOST-PLAN.md)). Always query live state: see the crate table below and run the gate commands for current counts.

## Build

```sh
cargo build --release
```

## Test

```sh
cargo test --workspace
cargo clippy --workspace --all-targets -- -D warnings
```

## Architecture

```
colibri-daemon (always-on Unix socket server)
  ├── glasspane      — agent state machine (zot/pi JSONL → idle/working/blocked/done)
  ├── store          — SQLite coordination (tasks, agents, skills)
  ├── socket         — newline-JSON socket API
  ├── session        — append-only JSONL sessions, 3-region prompt assembly
  └── spawner        — agent subprocess management (retry/backoff, FreeBSD jail confinement)

colibri-client       — CLI tools (colibri, colibri-test-agent)
colibri-glasspane-tui— ratatui dashboard
```

## Probe binaries

```sh
# DeepSeek cache probe (needs DEEPSEEK_API_KEY)
cargo run --release --bin colibri-probe

# Runtime inventory manifest
cargo run --release --bin colibri-runtime-inventory
```

## FreeBSD

Target `x86_64-unknown-freebsd` (Rust Tier-2). TLS uses `rustls` for clean
static linking (no `openssl-sys` dependency). Default DB path: `/var/db/colibri/colibri.sqlite`.
