An introduction · for scientists
A declarative engine for diagnostic data pipelines — where a result carries the method that made it, and a number remembers it is a measurement.
The ache
The figure is in the paper. The spreadsheet that made it left with the postdoc.
Your method lives inside an application's clicks — not written down, not portable, not yours.
Units on a label if you're lucky, uncertainty nowhere, and a mean of things that should never be averaged.
The turn
A Study is your data and your declared method, kept together and kept honest. You don't rent a seat — you keep a Study: as long-lived as your programme, as private as your laptop, as reproducible as a commit.
Its framework is the AFS; its built store is the KLS; you read it in the Explorer. We'll meet each where it earns its keep.
One word, many sizes
The method · the diamond
A diagnostic pattern over your gold data — a balance, an outlier, a stale reference — emitting standardized findings.
A plain-language hypothesis, scored against the evidence of its signals: confirmed, plausible, or not observed.
When a thesis is confirmed, a rule-based root cause — with a recommendation, and a trail back to every row.
You write YAML; jinflow compiles the SQL, builds the store, and serves the finding. Prior expertise enters too — as attributed Subject Matter.
Honest by construction
Every built store travels with the exact framework that produced it — the Imprint — stamped to a commit. Hand it over, and a colleague can see, and re-run, how every number was made. No black box, no lost macro.
Every column declares its kind, its unit (UCUM), how it may roll up, and its uncertainty (GUM). So a value isn't 35.1 —
35.1 µg/m³ ± 2.3 (1σ) · mass concentration · averageable
The engine won't average what mustn't be averaged.

Click a station on the map → its co-located pollutant streams → the measured series, with its uncertainty and reference line. Magnitude, not a yes/no threshold, does the colouring.
