Review #2 (MEDIUM). The M3 `[project.environments]` approval gate silently failed open in three shapes: - `EnvPolicy.confirm` was `#[serde(default)]`, so `production = {}` parsed as un-gated. `confirm` is now a REQUIRED field — an env listed with an empty policy is a load error (`missing field 'confirm'`), not a silent no-gate. - `pic apply --file <leaf>` where the leaf carried no `[project]` skipped the gate even when the repo root gated the env. `run` now discovers the governing `[project]` by walking up from the manifest to the nearest ancestor `picloud.toml` that declares one (`find_governing_project`, loaded without the env overlay — only the block matters). - A `[project].environments` in a non-root manifest under `--dir` was dropped with a generic "ignored" note; `build_tree` now warns explicitly that its approval gating is not enforced. Pinned by `tests/env_approval.rs` (empty-policy load error; leaf `--file` apply honoring the root gate). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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
