Adds /api/v1/admin/apps/{id_or_slug}/members[/{user_id}]:
- GET list members (joined with admin_users via list_for_app_enriched)
- POST grant membership — 201 with enriched DTO
409 on duplicate (promotions go through PATCH on purpose so
the UI can surface "already a member" cleanly)
422 if the target user is deactivated
422 if the target's instance_role isn't `member` — owners and
admins already have implicit authority, so an explicit row
would be dead weight
- PATCH change role — 200 with enriched DTO
404 if no existing membership (use POST to create)
- DELETE remove — 204, idempotent (matches the repo's `remove`
contract; 204 also when the row never existed)
All four gated on `Capability::AppAdmin(app_id)`. Editors and viewers
get 403 from list and never see the dashboard's Members tab.
No last-app-admin guard: owners implicitly satisfy AppAdmin via
`role_grants`, so removing the last explicit app_admin row cannot
permanently orphan an app — an owner can always re-issue grants.
Wires through picloud/src/lib.rs by splitting the Postgres app_members
repo Arc into two trait views (AppMembersRepository for CRUD, AuthzRepo
for the existing capability lookups) without re-instantiating against
the pool.

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
