Surfaced + fixed during the F3 attestation:
- executor-core/sdk/queue.rs: drop redundant .map(|()| ()) call sites;
enqueue_blocking discards QueueMessageId via .map(|_id| ()) (intentional)
- executor-core/sdk/retry.rs: hoist use std::collections::hash_map::DefaultHasher
+ use std::hash::Hasher to the top of the file (clippy::items_after_statements);
replace `as i64` casts with i64::try_from + clear comment about jitter
bound (clippy::cast_possible_wrap)
- executor-core/sdk/invoke.rs: move _LIMITS_IS_COPY const before #[cfg(test)]
mod tests (clippy::items_after_test_module)
- manager-core/dispatcher.rs: dispatch_one_queue gains #[allow(too_many_lines)]
(it's the queue tick's whole logic — split makes it less readable than
the lint); .map(...).unwrap_or(default) → .map_or(default, ...)
- picloud/lib.rs: Limits { trigger_depth_max, ..Limits::default() } via
struct-update instead of let-mut-assign (clippy::field_reassign_with_default)
- tests: r#"..."# → r"..." where there are no `"` inside (clippy::needless_raw_string_hashes);
combine InvokeTarget::Name | InvokeTarget::Path arms with identical bodies
in sdk_invoke.rs (clippy::match_same_arms)

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
