Thread extension-point markers through the manifest and the apply engine — a name-only resource modeled on `secrets` (shape) with `vars`-style create/prune write behavior. - manifest: top-level `extension_points = ["theme", …]` (allowed on app and group; overlay stays base-only via deny_unknown_fields); `build_bundle` emits the names. - apply_service: `Bundle.extension_points`, `CurrentState.extension_point_names`, `Plan.extension_points` (+ is_noop), `diff_extension_points` (declared→Create / live-undeclared→Delete / else NoOp), `load_current` loads them, `reconcile_node_tx` inserts on Create + deletes on prune, `state_token_with_names` folds in `ep|<name>`, `validate_bundle` rejects duplicates + reserved names, `ApplyReport` gains created/deleted counts. - CLI client + plan/apply rendering: `extension_points` in PlanDto/NodePlanDto/ ApplyReportDto, an `extension_point` row group in `pic plan`, a count in the apply summary. pull sets it empty for now (wired to the read endpoint in C4).

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
