Track public EV tariff data sources

[galjos]

Goal

Keep a live decision record for EV charging tariff data sources so pitstop can add per-station or operator-level pricing only when there is a reliable public source.

Scope

• Re-check AFIR/NAP consumer access, PUN/public portal behavior, Open Charge Map, OSM tagging, CPO tariff pages, and commercial providers.
• Record whether each source provides machine-readable EUR/kWh or session-price data, coverage, license/terms, and freshness.
• Distinguish per-station tariffs from operator tariff-page links.

Non-goals

• Scraping fragile web UIs without a clear legal and technical contract.
• Guessing prices from operator names.

Done when

• Source matrix is documented.
• Current recommendation is explicit: keep tariff page URLs, integrate a source, or revisit later.
• Any implementation follow-up has a bounded data contract.
