Phase 5 C5. Three `pic ... --dir` tree journeys:
* a group + a nested app apply atomically as one tree (the app's route binds
the group's same-apply `shared` script); the group node's script is
created; re-plan is all-noop (idempotent),
* one invalid node aborts the whole tree — the valid group node's script is
NOT created (true all-or-nothing),
* a `pic groups reparent` between `pic plan --dir` and `pic apply --dir` trips
the bound-plan (StateMoved) check via the tree's structure version.
Docs: `groups-and-project-tool.md` §11.5 status (✅ shipped — single-repo
nested tree apply; multi-repo single-owner + per-env approval gating deferred
per §11.1) + CLAUDE.md current-focus.
Gates: fmt, clippy -D warnings, cargo test --workspace, check-versioning (50
migrations — Phase 5 added none), schema snapshot unchanged, full journey suite
108/108. (Pre-existing flake `queue_e2e::queue_receive_acks_on_success` — a
racy immediate `count==0` after the async ack; flaky at the pre-Phase-5
baseline too, unrelated to this work.)

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
