stroblmeandClaude Opus 5 961a8f881d Keep the engine's state in SQLite, not Postgres
One process owns this database — the image has run a single uvicorn
worker for that reason since the four-engines bug — so a file beside the
flows is the honest shape for it, and it is what lets `fluksio serve`
need no infrastructure at all. Live values, node execution and the work
queue never came here anyway; what does is a rollup a minute at a time,
a row per cascade and the run history, and WAL keeps the readers going
while that one writer works.

DATA_DIR is now the one setting that moves everything an installation
keeps; the rest derive from it and the images still spell theirs out.
The schema is prepared in-process at startup, so the prestart service is
gone, and the ten Postgres-only revisions collapse into one portable
baseline.

Three things only worked because psycopg was casting for us: a token's
subject arriving as a string where the column is a UUID, `greatest`, and
`date_bin`. The timestamps needed a column type of their own — SQLite
stores no offset, and a naive datetime read back either raises against an
aware `now` or serialises as local time.

Postgres stays in the stack only for Umami, behind the analytics profile.

# Fluksio App
Fluksio has the goal to build a revolutionary system to tackle any sort of automation challenge.
The core of Fluksio: a node-based, test-driven automation software built to scale. This
repo holds the FastAPI backend, the flow engine, and the dashboard SPA. It is served on
`app.${DOMAIN}` (SPA) and `api.${DOMAIN}` (API); the marketing site lives in the sibling
`index` repo.
## Layout
```text
backend/ FastAPI + SQLModel + Alembic + SQLite
fluksio/flow/ the flow engine (nodes, pipeline, state backends, controller)
frontend/ React 19 + TanStack Router + Tailwind 4 + shadcn/ui
docker/ compose.yml → compose.dev.yml → compose.local.yml (+ compose.traefik.yml)
scripts/ generate-client.sh, test.sh
```
## Getting started
Normally driven from the workspace root (`make init` once, then `make dev`). Standalone:
```sh
make install # uv sync + bun install
make dev-utils # proxy and mailcatcher only
make dev-backend # FastAPI on :8000, hot reload
make dev-frontend # Vite on :5173
```
```sh
make test # pytest + Playwright (the e2e half needs the stack up)
make lint # ruff + mypy + biome
make generate-client # regenerate the frontend SDK from the OpenAPI schema
```
`make help` lists every target.
## Documentation
- [`ROADMAP.md`](ROADMAP.md) — strategy and feature record
- [`NOTEPAD.md`](NOTEPAD.md) — deferred work and findings
- [`DESIGN.md`](DESIGN.md) — points at the workspace root's `DESIGN-GUIDELINES.md`
- `docs/architecture/` in the sibling `docs` repo — the requirement sources
