Adversarial review of Phase 4-lite found two real gaps, both rooted in the
apply engine resolving script `id → name` from `current.scripts` (app-own)
only — so a route/trigger bound to an inherited GROUP script (whose id is not
app-own) couldn't be named:
* **Prune gap (reachable via pure declarative apply):** a trigger bound to an
inherited group script, once dropped from the manifest, never diffed to a
Delete (the diff couldn't resolve its identity once the bundle stopped
referencing the name), so `apply --prune` silently orphaned it.
* **Bound-plan false-negative:** `state_token` excluded such a trigger from
its fingerprint, so the StateMoved check missed a concurrent edit to that
binding class. (Routes were already safe — they hash the raw `script_id`.)
Fix: `resolve_current_target_names` resolves the names of group scripts the
app's CURRENT routes/triggers are bound to (by id, independent of the bundle),
and that map now feeds `compute_diff_with_names`, `state_token_with_names`, and
the prune trigger-identity map. App-owned bindings are unaffected (their names
are already in `current.scripts`). Also fixes a stale "in this app" conflict
message for group-owned scripts.
New journey `inherited_bound_trigger_is_pruned_when_dropped` proves prune now
removes an inherited-bound cron trigger. Full journey suite 105/105.

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
