Every non-KV mutating op now runs the same before/after interceptor machinery: - docs create/update/delete (+ group) — create/update honor the M4 data transform; - files create/update/delete (+ group) — allow/deny only (the blob is never surfaced to the hook, value = None); - queue enqueue (+ shared) — transform-capable; after reports the message id; - pubsub publish_durable (+ shared topic) — transform-capable; - http request — all verbs funnel through two svc.request sites; collection = method, key = url, body not surfaced. ictx threaded into the free-fn/handle paths that lacked it (http was _ictx; queue/pubsub per-app publish). validate_bundle_for generalized to a per-service allowed-ops map (kv set/delete; docs/files create/update/delete; queue enqueue; pubsub publish; http request) — unknown service/op still rejected. INVARIANT enforced + verified: every allowed (service, op) has a matching runtime hook, so no validated-but-unhooked fail-open. Pinned by a new docs-create deny journey (11 interceptor journeys green). Co-Authored-By: Claude Opus 4.8 (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
