impyard 0.1.0

Rent the intelligence, own the governance — a control plane for imps: software colleagues whose every action passes through a gateway you control (default-deny egress, injected credentials, budgets, approval gates, audit).

//! `impyard init` — initialize a deployment: the XDG config/data/state roots
//! and a starter org.toml. Idempotent; never overwrites an existing file.

const STARTER_ORG: &str = r#"# Impyard org config — ADMIN-ONLY. Applies to every imp (scope "org");
# per-imp overlays live in imps/<name>/imp.toml. Config loads live:
# check edits with `impyard server validate`.

# pi + the box extensions are baked into the impyard-box image. Developers
# iterating on them can mount a checkout over the baked engine instead:
# [engine]
# dir = "/path/to/impyard"

# Egress grants shared by all imps, e.g.:
# [[grant]]
# name = "web-fetch"
# host = "*"
# methods = ["GET"]

# Actions imps may propose ([[action]]), the trust ladder ([[trust]]),
# and budgets ([budget] + [[budget.limit]]) — see docs/cli.md and org.toml
# in an existing deployment for worked examples.
