MechaCat02 636106e9ea feat(quota): per-group total-byte quotas for shared KV + docs (Track A M4)
M3 quotas capped a group's shared KV/docs by ROW count only; a group could still
blow past storage with few-but-huge values. Add the symmetric total-bytes ceiling
(files already had one).

- group_quota: PICLOUD_GROUP_{KV,DOCS}_MAX_TOTAL_BYTES env vars (default 256 MiB)
  + accessors.
- GroupKvRepo/GroupDocsRepo: total_bytes(group) = SUM(octet_length(value::text))
  (default Ok(0) so non-Postgres impls skip the check).
- GroupKv/DocsServiceImpl: check the PROJECTED total (old value's bytes
  subtracted, new added) on every set/create/update, so a same-or-smaller update
  near the cap is still allowed (unlike a naive used+new check). New
  TotalBytesQuotaExceeded errors; +with_max_total_bytes for tests.
- KV set switched has->get to obtain the old value's size for the delta.

Pinned by group_kv_service + group_docs_service per_group_byte_quota_uses_the_
projected_total unit tests (reject over-cap, allow same/smaller update near cap).
No migration. CLAUDE.md env-var table updated.

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
