Prerequisites

podman, qemu-base, virtiofsd, boco

Build

scripts/build.sh

Creates configs/ssh/id_ed25519 (ops keypair, once), builds the podman image, then packs it as boco qcow2 into the boco registry.

Run

scripts/run.sh

This exposes the turnstone console on :8080, and ssh on :2222

LLM backend

Set up configs/turnstone/config.toml with an OpenAI-compatible endpoint.

Shares (virtiofs, survives reboots)

Host path	Guest path	Purpose
`configs/turnstone/`	`/home/marvin/.config/turnstone`	turnstone config.toml
`data/`	`/var/lib/turnstone`	SQLite database
`work/`	`/home/marvin/work`	agent workspace

Note that virtiofsd runs under podman unshare, which means that files written by the guest-VM will be owned by a subuid-range.

Configuration

Edit configs/turnstone/config.toml (see config.toml.example):

[models.<provider>] - LLM provider; api_key must be set.
[auth] jwt_secret - required, generate once.
[database] path - SQLite on the data/ share.
[tools] - workspace_dir surfaced to the model.

Personas

Turnstone offers a few built-in personas (Engineer, Writer, Researcher, Scribe, Manager, Executive), which are seeded by turnstone's migration.

This deployment adds a custom default persona marvin (VM-specific: persistence rules, Gitea remotes, podman) via scripts/persona.py - the prompt text is versioned there and re-applied after a DB reset:

python3 scripts/persona.py            # --db data/turnstone.db default

(Without a console deployment, persona CRUD is a direct SQLite write; with turnstone-console running, use its admin API/Personas tab.)

Skills

Skills are checked in under skills in the SKILL.md format. These are imported into turnstone's DB-backed catalog via scripts/import_skills.py. The script runs inside the VM.

scp -O -i configs/ssh/id_ed25519 -P 2222 -r skills scripts/import_skills.py \
    marvin@localhost:/tmp/
ssh -i configs/ssh/id_ed25519 -p 2222 marvin@localhost \
    /opt/turnstone/bin/python /tmp/import_skills.py --dir /tmp/skills

Idempotent (--update re-imports + appends version rows). Reboot the VM after importing - the running server holds a stale WAL snapshot and won't see new rows until restart.
