email_trigger_details.inbound_secret_encrypted was sealed v0 (no AAD, bound only
to the master key) because the table had no version column — a ciphertext could
in principle be relocated between rows (audit 2026-06-11 H-D1, Medium). Bring the
AAD versioning the `secrets` table gained in 0042 to email secrets.
- Migration 0069: `email_trigger_details.inbound_secret_version SMALLINT DEFAULT 0`.
- secrets_service: `seal_email`/`open_email` seal v1 with AAD bound to the
SEALING OWNER (`email:{app}` / `email:group:{group}`) — deliberately NOT the
per-row trigger_id, so a group template's sealed bytes stay valid when the
materializer copies them verbatim to each descendant (all share the group AAD).
v0 rows keep their exact legacy no-AAD read path.
- Both email-trigger create paths (declarative apply resolve_and_seal +
triggers_api create_email_trigger) seal v1 under the trigger's owner; the
version threads through CreateEmailTrigger + insert_email_trigger_tx.
- materialize copies inbound_secret_version verbatim with the bytes.
- email_inbound_target recovers the sealing owner (materialized_from ->
template.group_id, else the app) so receive_inbound_email opens a v1 secret
under the right AAD.
Cross-app/tenant relocation now fails the GCM tag; a same-owner swap is not
distinguished (accepted low-severity residual). Pinned by
email_secret_aad::materialized_email_copy_decrypts_under_the_group_aad (the
novel materialized-copy path) + the extended secret_round_trips_through_seal_open
lib test. Schema golden reblessed; materialization + email e2e regressions green.

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
