MechaCat02 ca360d84cb docs(design): record Phase 3 shipped + the live-resolution decision
Phase 3 (group-inherited config) is implemented, so fold the outcome back
into the design doc (per its own "before it drifts" note) — and flag the
one deliberate divergence from the plan.

§5.1 / §11.3 / §12 prescribed a *materialized* per-app effective view with
a generation counter and fan-out invalidation. We shipped **live,
resolve-on-read inheritance** instead: one recursive CTE per
`vars::get`/`secrets::get`/`config/effective`, no cache. The org tree is
small and there was no pre-existing config cache to fight, so this is
cheap and sidesteps §10's unsolved invalidation SLA.

Records, mirroring the Phase 1/2 status blocks:
* a "Status (Phase 3):  shipped" block in §11.3 with the full surface
  (0048/0049 schema incl. `apps.environment`, the §3 resolver, vars SDK +
  CRUD, group-secret AAD + inherited read, the two secret gates, masked
  `config/effective`, `--explain`) and the live-vs-materialized rationale;
* §5.1 runtime-model bullet annotated as the deferred (Phase-4 script
  inheritance) design, not Phase-3 runtime;
* §10 "invalidation SLA" and "inherited-membership revocation lag" marked
  moot/resolved — no cache means immediate propagation;
* §12 resolver contract + the header framing updated to live resolution.

Doc-only; no code change.

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
