UsersService trait in shared::users + Postgres-backed impl in
manager-core::users_service. Wired into the Services bundle (new
`users` field) and the picloud binary's startup.
Commit 4 ships:
* CRUD: create / get / find_by_email / update / delete / list
(cursor-paged on created_at). create validates email shape,
8-char password minimum, optional display_name; throws
DuplicateEmail on (app_id, lower(email)) collision.
* Auth: login (timing-flat — runs verify_password against the
shared dummy Argon2id PHC even on email miss, so the
bad-email and good-email branches share wall-clock cost);
verify (sliding TTL bump capped at absolute_expires_at);
logout (revoke by token).
* verify_session_for_realtime — non-SDK method taking app_id
explicitly; used by the F3 realtime auth_mode='session' path
in a later commit.
* Cross-app isolation everywhere: cx.app_id (or explicit app_id)
is the only source of truth; a logout for a foreign-app token
is a silent no-op rather than a probe of session existence.
Email-tied flows (verification, password reset, invitations), roles,
and admin-mediated helpers are stubbed UsersError::Backend and ship
in later commits in this series.
Config (UsersServiceConfig) sources from env with documented
defaults:
PICLOUD_APP_USER_SESSION_TTL_HOURS (24)
PICLOUD_APP_USER_SESSION_ABSOLUTE_HOURS (720 = 30d)
PICLOUD_APP_USER_VERIFICATION_TTL_HOURS (48)
PICLOUD_APP_USER_PASSWORD_RESET_TTL_HOURS (1)
PICLOUD_APP_USER_INVITATION_TTL_DAYS (7)
Reserved a TIMING_FLAT_DUMMY_HASH constant on manager-core::auth so
the dummy PHC is one shared definition.
Added AppUserId + InvitationId id types in picloud-shared.

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
