A 70-line newtype lived in picloud/src/lib.rs wrapping Arc<PostgresScriptRepository> and re-implementing every ScriptRepository method as `self.0.method(...).await`. Hand-delegation invited silent skew when the trait gained a method, and forced 8 call sites to know about the wrapper. Add a blanket impl<T: ScriptRepository + ?Sized> ScriptRepository for Arc<T> in manager-core::repo. The implementations forward via (**self).method(...) so any owner of an Arc<dyn ScriptRepository> (or Arc<ConcreteImpl>) can be passed where the trait is expected. Migrate the 7 picloud-binary call sites: Arc::new(PostgresScriptRepoHandle(script_repo.clone())) → script_repo.clone() Delete the newtype + its hand-delegated impl. Leaves a 6-line comment documenting why the boilerplate is gone. AUDIT.md anchor: F-Q-011. Co-Authored-By: Claude Opus 4.7 (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
