Pins the user-visible Rhai SDK behaviors to a concrete test file so
SemVer enforcement isn't aspirational. **Editing this file is an SDK
version bump event** — the file header documents the rule.
* 30 tests covering every documented SDK 1.0 + 1.1 surface:
ctx.sdk_version (format + feature-detection)
ctx.execution_id / request_id / script_id (UUID shape)
ctx.script_name (round-trip)
ctx.invocation_type (http / function / scheduled)
ctx.request.path / headers / body / params / query / rest
log::trace / info / warn / error (with and without data)
response convention: bare value → 200, structured map →
statusCode pass-through, missing statusCode → wrapped 200,
non-integer statusCode → InvalidResponse error
sandbox restrictions: imports blocked, print disabled,
log::debug rejected (Rhai keyword — use log::trace)
JSON type fidelity (string/int/float/bool/null/array/object/
nested round-trip)
* Separate from tests/engine.rs (which tests internal Engine
behaviors) — same crate, different audience: engine.rs is
"does the engine work right", sdk_contract.rs is "does the
public contract hold". Some overlap is intentional so the
contract is readable in one place.
* Plain cargo test --workspace runs all 30 (no infrastructure
needed); these are pure unit tests.

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
