Two clean, local dedups in the group shared-collection services: - Extract `GroupKvServiceImpl::check_value_size` — `set` and `set_if` inlined the identical encode-and-cap block; now one method (mirrors the sibling `group_docs_service::check_data_size`). - Add `group_collection_repo::best_effort_emit_shared` — the KV/docs/files services each copied the same emit-and-log-on-error tail for shared-collection triggers. Centralize the tail (logging the event's own `source`/`op`); each service still builds its own `ServiceEvent` (payload shapes differ). Pure refactor, pinned by the existing group-service unit tests. (The `owning_group` resolver was evaluated for dedup too but left as-is: the five error enums diverge — `GroupFilesError::InvalidCollection` carries a `String`, `GroupPubsubError` lacks the variant, and files/pubsub skip the empty-check kv/ docs/queue do — so a shared conversion would be a behavior change, not a refactor.)

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
