Three related fixes from the test audit. **The CLI journey fixture gets its own database.** It spawned a real picloud — whose dispatcher/orchestrator claim loops are global by design (one instance owns one database) — against the shared dev DB, so it could claim the manager-core suites' outbox/workflow rows (the same class of bug already fixed for the e2e suites, one binary over). It now clones one dedicated database per journey run from the migrated template. test-support gains `named_test_db_url` (explicit stable name) + a blocking wrapper for the sync `LazyLock` fixture. The one journey that talks to Postgres directly (dead-letter injection) now uses the fixture's DB URL, not the base DATABASE_URL, so it hits the database the server reads. **workflow_orchestrator moves to per-test databases.** Its `claim_ready_step` is global, so the old harness serialized every test behind a process-wide CLAIM_LOCK AND ran `DELETE FROM workflow_runs` (unscoped — it wiped every app's runs) before each one. A private database per test makes the global claim see only that test's rows, so both the lock and the unscoped DELETE are deleted. **DB-backed suites fail loud instead of skipping green.** ~15 manager-core suites `return None` when DATABASE_URL is unset and report PASS — so in any environment that lost its database the entire integration surface reports green while running nothing (why the CI gap went unnoticed for so long). New `picloud_test_support::abort_if_db_required` panics when `PICLOUD_REQUIRE_DB` is set (CI now sets it) but DATABASE_URL is not, injected into each suite's skip path. Local runs without the var still skip cleanly. Mutation-verified: with PICLOUD_REQUIRE_DB=1 and DATABASE_URL unset, a suite panics; without the var it skips.

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
