App-user session storage (migration 0027) mirrors admin_sessions but
adds three things v1.1.8 needs:
* app_id column + FK cascade — every v1.1+ table starts with app_id
so cross-app isolation is bright at the SQL layer (lookup keys
off the hash only, but defense-in-depth: a leaked row's session
still scopes to its app on every read).
* absolute_expires_at — hard cap on the sliding window (default 30d
via PICLOUD_APP_USER_SESSION_ABSOLUTE_HOURS). Beyond this the
user must re-login regardless of recent activity.
* revoked_at — explicit revocation by token (logout) or per-user
(admin revoke-sessions button, password reset). Lookups reject
revoked rows immediately so revocation takes effect before the
weekly GC sweep runs.
The repo's gc() uses FOR UPDATE SKIP LOCKED matching the dead-letter
and abandoned-executions sweep patterns; the GC wiring lands in a
later commit.

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
