MechaCat02 d1de43e919 feat(authz): GroupKvRead/GroupKvWrite capabilities (§11.6 C2)
The shared-scope authz refinement for group collections. Two group-scoped caps
resolved via the existing group ancestor walk (effective_group_role):
GroupKvRead = viewer+, GroupKvWrite = editor+. Wired into app_id() (None —
group caps carry no app_id, so a bound API key is denied at the binding layer),
required_scope() (ScriptRead / ScriptWrite), the Member→group_member_grants
route, and group_role_satisfies. Unit test covers viewer-reads-not-writes,
editor-writes, outsider-denied, bound-key-denied up the chain.

The reads-open/writes-authed trust split (anonymous read bypass; anonymous
write fail-closed) is enforced at the service layer in the next commit — these
caps are the authenticated-principal refinement on top of the structural
subtree boundary.

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
