MechaCat02 902dd78027 feat(picloud): opportunistic principal middleware on the data plane
The data-plane (POST /execute/{id} + user-route fallback) is
unauthenticated by default — public scripts get hit by anonymous HTTP
traffic. But some calls are authed (dashboard test-runs, API-key
invocations) and v1.1.x services will want to see the caller via
`cx.principal` for audit / authz once those features land.

  - New manager-core::attach_principal_if_present middleware. Always
    inserts Extension<Option<Principal>>: Some on resolved bearer/cookie,
    None on absent or malformed token. Fail-open on DB blip so a
    transient infra failure can't 500 anonymous traffic.
  - Wired in picloud build_app, scoped to the data-plane and user-routes
    routers only. The admin path keeps using require_authenticated; no
    double-resolve on the same token.
  - orchestrator-core handlers (execute_by_id, user_route_handler) now
    extract Extension<Option<Principal>> and pass it to build_exec_request.
    Replaces the temporary `None` placeholders from the previous 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
