MechaCat02 65049a6262 feat(apply): owner-generic apply engine — group-node plan/apply (Phase 5 C1)
Phase 5 C1. Generalize the reconcile engine from app-only to an `ApplyOwner
{ App | Group }`, so a GROUP's own config + scripts can be declaratively
reconciled — the foundation for the tree-spanning project tool.

A group node is a subset of an app node (scripts + vars only; no routes /
triggers / secrets-values), so the diff, script/route/trigger/var CRUD, prune,
idempotency, and the Phase-4 inherited-target resolution are all reused
unchanged. Only the owner-varying bits switch on `ApplyOwner`:
  * `load_current` — `list_for_group` + `VarOwner::Group` for a group (empty
    routes/triggers/secrets); `list_for_app` for an app, exactly as before.
  * script create owner (`NewScript{app_id|group_id}`), var writes (new
    `set_group_var_tx`/`delete_group_var_tx` mirroring the app variants at
    scope `*`), and the advisory lock (owner-tagged).
  * `validate_bundle_for` rejects routes/triggers on a group bundle (422);
    route-host validation, inherited-target resolution, the post-commit route
    refresh, and the unreachable-endpoint warning are app-only.

`apply`/`plan` are unchanged thin wrappers over the new `apply_owner`/
`plan_owner`. New endpoints `POST /groups/{id}/{plan,apply}` gated by
`GroupScripts{Read,Write}` / `GroupVarsWrite`. `ApplyService` gains a `groups`
repo (the tree apply in C3 needs it too).

Live-validated: group plan → apply (group-owned script + var) → idempotent
re-plan noop → routes rejected 422 → DB confirms group ownership. App apply
unchanged: 391 manager-core unit tests + the apply/prune/staleness/overlay
journeys all green.

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
