A node's error cleared the moment it ran again, so a failure that genuinely fired an alert could leave no trace on the canvas by the time anyone looked. The engine records it now — on the node's status, so it survives a reload and every client agrees — and reading the traceback is what clears it. The seam is the event bus, which is where every failing path already meets: a queued live run, an explicit run, a preview, and a single triggered node all publish `node_error`, while the controller's own observer would have seen only one of them. That was half the confusion. The other half: clicking a failed neuron on Home often landed on a flow where everything looked fine. Nodes merge into one neuron by instance key — every InfluxDB node pointing at the same bucket is one neuron — and the click went to whichever flow contributed a member first, not the one that failed. It now goes to the failing member and selects it, and the canvas marks a failing node rather than leaving it to the dot alone. The inject node emitted one payload to every port it declared, whatever their types, so an inject on a bool port carrying the text "true" raised at publish time. Each port gets its own field now, typed and parsed by that port's dtype, and remembers what it last sent. A port that is renamed carries its value with it; one that is removed takes its value with it. An inject written before this keeps emitting exactly what it did. The derived-cron chip also appeared on the delay node, where `interval` is a rate limit and a schedule derived from it means nothing.

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
backend/ FastAPI + SQLModel + Alembic + Postgres
app/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:
make install # uv sync + bun install
make dev-utils # db, adminer, proxy, mailcatcher, prestart only
make dev-backend # FastAPI on :8000, hot reload
make dev-frontend # Vite on :5173
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.
