v1.1.7 added at-rest encryption for app_secrets.realtime_signing_key
plus a startup task that backfilled encryption over the plaintext
column. v1.1.7's CHANGELOG committed v1.1.8 to dropping the
plaintext column; this commit follows through.
Migration 0032:
* Guard query: refuses to apply if any row still has
realtime_signing_key IS NOT NULL but realtime_signing_key_encrypted
IS NULL. Forces operators who skipped v1.1.7 to apply it first.
* ALTER TABLE app_secrets DROP COLUMN IF EXISTS
realtime_signing_key.
app_secrets_repo:
* decode_signing_key now reads encrypted+nonce only; the plaintext
fallback is gone. (The schema still allows it via DROP IF EXISTS
semantics on replay; once dropped, the column doesn't exist —
the SELECT no longer requests it.)
* Removed migrate_plaintext_keys (the v1.1.7 startup sweep).
* Tests for the falls-back-to-plaintext path are gone with it; the
remaining tests cover the encrypted-only happy path, the
missing-columns None case, and the wrong-master-key Crypto error.
picloud/lib.rs: removed the migrate_plaintext_keys startup call
+ replaced with a comment explaining the upgrade-path requirement.
LOAD-BEARING: v1.1.8 requires v1.1.7 to have been applied first.
Operators upgrading directly from v1.1.6 or earlier must apply
v1.1.7 (which performs the encryption pass) before applying v1.1.8.
This is enforced both by the migration guard and by the CHANGELOG
(in a later commit).
Brief mentioned dropping a "realtime_signing_key_nonce_LEGACY_IF_EXISTS"
column — recon confirmed migration 0025 only added the plaintext
column + the encrypted/nonce pair, so no legacy nonce column exists
to drop. Documented in HANDBACK §7.

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
