feat(ev): use the BNetzA Ladesäulenregister for Germany instead of Open Charge Map - #143
Conversation
The alignment test checks that every EV_XX scraper key appears in all three tables: the interval defaults and the factory map in instrumentation.ts, and SCRAPERS in the CLI. Its regexes matched only \`EV_\` plus a two-letter country code, so a key with a source suffix such as EV_ES_REVE stopped matching at \`EV_ES\`, found no \`:\` after it, and was silently dropped from the comparison. The guard was blind to exactly the country-specific official registries that are most likely to be added to one table and forgotten in another. The regexes now accept an optional _SOURCE suffix. Nothing changes for the plain EV_XX keys.
The Ladesäulenregister is the register every operator of a publicly accessible charge point in Germany must file into under §5 Ladesäulenverordnung, so it is authoritative where Open Charge Map is crowdsourced, and several times larger (~74,000 locations). It is published as one daily bulk TSV, needs no API key and no signup, and is CC BY 4.0 with the attribution string "Bundesnetzagentur.de". This commit adds the scraper and its tests only. Nothing imports it yet, so behaviour is unchanged; the wiring follows in the next commit. Two things shape the implementation: Rows are per charging facility, not per location, so one garage is five identical rows. Those are merged on a 5-decimal (~1 m) coordinate key, and that same key is the externalId. It has to be the same function: base.run() upserts in 500-row batches with a single multi-row INSERT ... ON CONFLICT, which Postgres rejects with a 21000 cardinality violation when two rows in one statement share a conflict target. On the real file 1,136 coordinates carry two street spellings, so keying the id on anything coarser than the merge key would mint exactly that many duplicate ids and silently discard whole batches. base.run() only orphan-cleans price-less fuel stations, so EV rows are never garbage-collected. A derived id churns whenever an operator corrects its coordinates, and each churned id would leak a permanent pin. run() therefore sweeps rows not touched by the current run, and retires the Open Charge Map rows for Germany that this source replaces. Both sweeps are gated on a database-counted floor (PUMPERLY_BNETZA_MIN_STATIONS, default 10,000) so a degraded fetch can never delete a working map. Coordinates are validated with a strict decimal regex rather than z.coerce.number(), which would turn a blank cell into Null Island, and rejected outside a padded German bounding box. Columns are resolved by header name so an inserted column upstream fails the run instead of swapping latitude and longitude.
Germany now has two EV sources: Open Charge Map (EV_DE, crowdsourced, needs an API key) and the BNetzA Ladesäulenregister (EV_DE_BNETZA, official, keyless, several times larger). They must never both run. The two overlap heavily, so running both double-pins the country, and once the BNetzA scraper has retired the ocm- rows a single stray Open Charge Map run puts every one of them straight back, because nothing garbage-collects EV rows. BNetzA wins by default: it is official, complete, and needs no signup. PUMPERLY_DE_EV_SOURCE=ocm keeps Open Charge Map instead. The rule lives in one function, germany-ev-source.ts, called by both the scheduler and the manual CLI, for the same reason as spain-ev-source.ts: two copies would drift, and the drift is silent. Unlike Spain's REVE handover there is no backfill period. The register arrives complete in one daily file, so Open Charge Map stops being scraped for Germany and its existing German rows are retired on the first healthy run. Naming EV_DE explicitly on the CLI still runs it. The legal modal gains the CC BY 4.0 attribution the licence requires.
README: list the Ladesäulenregister alongside Open Charge Map and Mapa REVE in the features and EV sources table (CC BY 4.0, attribution "Bundesnetzagentur.de"), explain the default switch for Germany and the PUMPERLY_DE_EV_SOURCE=ocm opt-out, and add PUMPERLY_DE_EV_SOURCE and PUMPERLY_BNETZA_MIN_STATIONS to the environment variable table. .env.example: the same two variables with their defaults and the reason the safety floor exists.

The safety floor counted every bnetza- row in the table, old and new alike. With 74,000 rows from yesterday and a degraded fetch that refreshed only 42, the count still cleared PUMPERLY_BNETZA_MIN_STATIONS, so the stale sweep deleted the 74,000 and the retirement sweep dropped the OpenChargeMap rows, leaving Germany with the degraded dataset. The count now carries the same updated_at cutoff the stale sweep uses, so only rows written by this run can vouch for it and every row sits on exactly one side of the cutoff. Adds a regression test with 74,000 stale rows and 42 refreshed ones that fails against the previous query.

) `PUMPERLY_BNETZA_MIN_STATIONS=0.5` floored to `0`, and `refreshed < 0` is never true, so the guard on the BNetzA scraper's two destructive sweeps (stale-row prune, Open Charge Map retirement) was silently gone for anyone who set a fractional or zero floor. `base.run()` still blocks a truly empty fetch, so this needed a misconfigured floor plus a degraded fetch to bite, but a guard that can be turned off by a typo is not a guard. Values that floor below 1 now fall back to the 10,000 default, the same as a non-numeric value. The regression test covers `0.5`, `0` and `-3` and fails against the previous line. Also fixes the README feature bullet that still claimed Open Charge Map covers every country (Germany and Spain use their official registries). Follow-up to #143, from CodeRabbit's post-merge finding.
…tors (#145) Sharing an EV charger produced `/es?station=ES:reve-…&lat=…&lng=…` with no fuel. A fresh visitor opened that on the default fuel (Diesel A); the viewport fetch is fuel-filtered, so the charger never loaded and the deep-link resolver, which only matches loaded features, never opened the popup. The visitor saw diesel stations around the spot with no hint anything failed. Since #143 every German charger link is affected too. Fixes #129 the way the issue sketched it: - `buildStationQuery` carries the fuel the station was shared from (popup share/copy, and the URL the app writes on selection). - `readDeepLink`'s station branch validates and applies `fuel` exactly like the route branch already did. Links without a fuel behave as before (default fuel), and an invalid code is ignored. Regression tests on all three layers (URL helpers, popup share link, HomeClient deep-link read); each was checked to fail against the unfixed code.
Summary
Germany's EV chargers now come from the BNetzA Ladesäulenregister, the register every
operator of a publicly accessible charge point must file into under §5 Ladesäulenverordnung.
It replaces Open Charge Map as the default German EV source: official instead of
crowdsourced, ~74,000 locations instead of a fraction of that, no API key, no signup.
CC BY 4.0 with the attribution "Bundesnetzagentur.de" (added to the legal modal).
Nothing changes for self-hosters who do nothing: Germany switches to BNetzA on the next
scrape.

Data source caveat
The scraper fetches
https://lade.info/data/stationen_XXXX.txt, a daily ~19 MB TSVre-export of the register maintained by lade.info, not bundesnetzagentur.de itself. The
official download is a monthly CSV whose filename changes every release, which does not
suit an unattended daily scraper. If you would rather depend only on the official file,
I am happy to switch the fetch and add a filename discovery step in a follow-up.
