Two follow-ups on the Rhai formatter shipped in 0.5.1.
* Formatter no longer collapses user-intent blank lines between
statements. The lexer now records a side-channel list of offsets
where the source contained two-or-more consecutive newlines; the
formatter consults it and emits a single blank in the same spot
(rustfmt's `blank_lines_upper_bound = 1` policy applied strictly —
the prior forced blank between top-level `fn` decls is dropped, so
the formatter never *adds* a blank the user didn't write).
* Parse errors now read like Rhai's own diagnostics. `expect()` takes
an optional `role` hint and each call site supplies a domain phrase
(`name of a variable`, `function name in function declaration`,
`'{' to begin a block`, `name of a property`, …). End-of-input is
reported as `script is incomplete`. The dashboard banner renders
`Parse error: {message} (line L, position C)` with 1-based
coordinates, matching Rhai's format exactly.
The FormatError payload also keeps the byte `offset` so callers that
want to drive the editor cursor (CodeMirror works in offsets) still
have it.
Also folds the workspace Cargo.lock version bumps for 0.5.1 — the
lock-file rewrite that should have travelled with the prior commit.

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
