list_for_script used ORDER BY created_at DESC LIMIT $2 OFFSET $3.
Postgres has to scan + discard OFFSET rows on every page, so deep
pagination on a script with many log rows gets linearly slower. Every
sister-table list endpoint in the repo already uses cursor pagination
— this is the outlier.
Add ExecutionLogCursor { created_at, id } with `<rfc3339>_<uuid>`
encode/decode. New trait signature:
list_for_script(script_id, limit, cursor: Option<ExecutionLogCursor>)
Predicate: WHERE script_id=$1 AND (created_at, id) < ($cursor_ts, $cursor_id).
ORDER BY also gains `id DESC` for deterministic ordering at equal-time
boundaries.
API surface:
- /api/v1/admin/scripts/{id}/logs?cursor=<token>&limit=50 is the new
shape (dashboards adopt later — separate finding F-U-012).
- Legacy `offset` query param accepted-and-ignored to keep older
dashboards from 400'ing during rollout.

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
