Both methods short-circuit the authz gate when cx.principal == None. An attacker hitting any public route could trigger unbounded outbound email per call to arbitrary or attacker-supplied addresses — exhausting SMTP-relay quota, getting the relay blacklisted, or burning provider credits. Add an in-memory EmailRateLimiter on UsersServiceImpl with two scopes: - Per-(app, recipient): 5 calls per rolling 1h window - Per-app daily cap: 200 calls per rolling 24h window Both windows reset lazily. Token-bucket counts increment only after both checks pass — a denied recipient doesn't consume the app counter. Wired: - send_verification_email: returns UsersError::EmailRateLimited (→ 429 on the admin HTTP surface). - request_password_reset: returns Ok(()) silently on rate-limit (would otherwise enable an existence-leak side channel). UsersError::EmailRateLimited variant added; AppUsersApiError gains the same variant + 429 mapping. NoopUsersError trait stub unaffected. AUDIT.md anchor: F-S-002.

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
