MechaCat02 2b27012f56 feat(groups): schema + root-group backfill (migration 0047)
Phase 2 (blueprint §5): groups form a single-parent org tree ABOVE apps.
This migration adds the tree + membership tables and gives every app a
parent (§9 adoption):

- groups: id, parent_id (self-FK ON DELETE RESTRICT), slug (instance-
  global UNIQUE, frozen at creation), name, description, structure_version
  (bumped on structural mutation), owner_project (inert §7 seam).
- group_members: (group_id, user_id, role) with the SAME three role
  literals as app_members so AppRole round-trips and the authz rank table
  covers both.
- apps.group_id: nullable add → backfill every app under a seeded 'root'
  group → promote to NOT NULL + FK RESTRICT.

No group-owned resources yet (scripts/secrets stay app-owned — Phase 3).

PiCloud

A lightweight, self-hosted, event-driven serverless compute platform. Upload a Rhai script, get an HTTP endpoint. Designed to run on a single modest server with no idle CPU cost, and to scale out to a small cluster when you need it.

Status: Phase 1 — MVP scaffolding in progress.

The authoritative design lives in serverless_cloud_blueprint.md.

Why

Existing serverless platforms are either cloud-locked, heavyweight, or both. PiCloud aims for the opposite end of the spectrum: one binary, one database, one reverse proxy — running on hardware you already own.

Architecture (one paragraph)

PiCloud splits into three logical services — manager (control plane: scripts, schedules, dashboard), orchestrator (per-node event ingress and dispatch), and executor (per-node Rhai sandbox) — each backed by a *-core Rust library. In MVP they run in a single process; in cluster mode they run as three binaries with one manager and one orchestrator + executor per node. Caddy fronts everything; PostgreSQL is the single source of truth.

See CLAUDE.md for working notes and serverless_cloud_blueprint.md for the full design.

Quick Start

Coming as scaffolding lands. For now:

# Rust toolchain (pinned via rust-toolchain.toml)
cargo check --workspace

# Run the all-in-one MVP binary (once main.rs is wired up)
cargo run -p picloud
