The runtime for shared group docs collections, mirroring the group-KV vertical with the docs surface (filter parsing, JSON-object validation, value-size cap). - shared: GroupDocsService trait + GroupDocsError (+ CollectionNotShared) + NoopGroupDocsService; group_docs field on Services + with_group_docs(). - manager-core: GroupDocsServiceImpl — owning_group resolves kind='docs' from cx.app_id's chain (CollectionNotShared off-chain); reads-open (script_gate GroupDocsRead) / writes-authed (script_gate_require_principal GroupDocsWrite); reuses parse_filter + docs value-size cap; no events. Unit tests cover off-chain CollectionNotShared, anon-read-OK/anon-write-Forbidden, non-object data rejected. - executor-core: GroupDocsHandle + docs::shared_collection constructor + the create/get/find/find_one/update/delete/list methods (dispatch by receiver type), reusing doc_to_map/parse_doc_id. - picloud: wire PostgresGroupDocsRepo + GroupDocsServiceImpl.

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
