A re-review of eaf5ace surfaced three follow-ups, all in the fixes themselves:
- pull vs an old server: a returned empty `definition` can only mean a server
predating the definition-in-list field (a real zero-step workflow is rejected
at apply). Emitting a stepless `[[workflows]]` block would just fail the next
apply, so `wire_workflow_to_manifest` now warns and skips it instead.
- base_ms/backoff defaults: the pull mapper keyed its default-omission off a
hardcoded `500` literal. `default_base_ms` is now `pub` + re-exported, and the
mapper omits whatever equals `default_base_ms()` / `WorkflowBackoff::default()`
— no drift if a default ever changes.
- dashboard: a run that succeeds with an `on_error = continue` step failure now
carries a partial-failure note in `run.error` (from the compute_advance
change); the run-detail view rendered it as a red failure, contradicting the
green "succeeded" badge. It now renders as a `.notice` (warning) for a
succeeded run, `.error` only for a failed one.
Verified: fmt + clippy -D warnings clean; 450 lib tests; 5 workflow CLI
journeys (incl. the pull→plan round-trip); dashboard npm run check clean.

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
