useEndpoint(path) returned `{ get: () => useResource(...), post: (body)
=> useResource(...) }`. Each of `.get()` and `.post()` called useState
+ useEffect — but React's Rules of Hooks require hook calls at the top
level of a component, in the same order each render. Calling
.get() conditionally, or both .get() and .post() from the same
component, produced undefined behaviour (state leaking between them).
The test suite covered only useTopic, so this was uncaught.
Separately (F-T-002): the JSDoc said .post() was "the mutation variant
(auto-fires once per mount)" — but auto-firing a POST on mount means
typo'd code creates a user (or sends an email) on every render refresh.
Refactor:
- Remove useEndpoint entirely (public API breaking change — clients/ts
v1.1.x has no external consumers yet per CLAUDE.md).
- Add useEndpointGet<Res>(path): QueryState<Res> — flat hook, auto-fires.
- Add useEndpointPost<Req, Res>(path): { mutate, data, loading, error }
— flat hook, event-driven (NOT auto-firing); call `mutate(body)` from
the submit handler.
README updated to demonstrate both shapes side-by-side.
Existing 15 unit tests pass (useTopic unaffected; useEndpoint tests
never existed). Adding a useEndpointGet/Post test pass is finding
F-T-001 follow-up.
AUDIT.md anchor: F-T-001 (+ F-T-002 folded in).

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
