Changelog

Rate limiting on CapyDB K/V.

• changedAPI rate limits and duplicate-submission protection run on CapyDB K/V instead of database tables; limits are unchanged.
• changed/api/health also reports the rate-limit store (kv) and is healthy only when it is reachable.

Honest numbers, working tools, one source of truth per rule.

• fixedThe calculator and portfolio showed paying above market rent as a saving (a €611/month overpayment appeared in green); above-market rent is now shown as an overpayment.
• fixedBudget Advisor failed on every request; it now matches the scoring service's response and labels results from the request you sent.
• fixedContact form submissions failed against the analytics database until migration 6.0.3 was applied; resending a stored message now confirms it instead of showing an error.
• fixedDataset pages silently showed only the newest 1,000 rows across all countries; every country's history is shown, with "latest N of M" when older data is left out.
• fixedValues stored in millions of euros were divided by a million again (€15,062M showed as €0.02M).
• fixedValues impossible for their unit (for example wage levels stored as a percentage) are withheld and marked "Data under review" instead of being shown as "+18373.7%".
• fixed"Live" badges now reflect how recent the data is ("Data through …"), not whether a request succeeded.
• fixedThe category page never rendered; it now loads, and unknown categories show a not-found message.
• fixedA malformed dataset link shows the not-found page instead of "temporarily unavailable".
• fixedThe comparison radar asked for datasets that do not exist and dropped them; it now uses five comparable indicators and inverts lower-is-better axes.
• fixedThe globe showed the United Kingdom and omitted France.
• fixedScoring errors (validation, rate limits, service outages) each show their own message instead of a generic timeout.
• fixedMarket timing shows seasonal results when only the momentum calculation fails.
• fixedModel monitoring labels errors in index points (not euros), shows unknown values as "—" instead of 0, and lists recent training runs and their failures.
• fixedThe quality monitor shows the latest check per dataset and flags stalled ingestion runs.
• fixedStatus pages judge FairRent coverage on models as well as data.
• fixedThe public average model fit uses the latest model per country (88%, previously 78% from every historical run).
• fixedSigned-out visitors to protected pages land on the app's own sign-in page, and the sign-in form follows the language switcher.
• fixedHover and placeholder styles on the marketing site now apply; the theme toggle follows your system setting.
• addedBookmarks for datasets, with a "Bookmarked" filter in the catalog.
• addedThe portfolio list is kept in your browser across reloads.
• addedLinks from Explore and the dashboard into the calculator, market overview and timing for the selected country.
• addedAn admin inbox for contact inquiries with a triage workflow.
• addedMobile navigation in the platform app; signed-in visitors get "Open app" on the marketing site.
• addedPage titles and descriptions for every page, a sitemap and robots.txt.
• addedMotion respects the system "reduce motion" setting.
• changedMarketing pages now describe what exists: the real API contract, the 0–100 FairRent Score with its A–F fairness grade, live coverage figures, and pricing as a free account plus platform access by agreement. Invented metrics, named customers, API keys, SDKs, webhooks and certifications that are not in place were removed.
• changedEvery API route is rate limited; public health and statistics endpoints are cached.
• changedPublic health endpoints no longer return internal database error text.
• removedThe duplicate /api-hub/status and the "coming soon" /api-hub/metrics pages (use /status).
• removedThe unreachable /product-tour page.

App states and API contracts.

• addedBranded not-found pages, destination-aware loading screens and inline error states.
• addedClient error reporting.
• addedDurable request coordination (rate limits, idempotency) and contact deduplication.
• changedProtected analytics and FairRent endpoints require a session or the admin role.
• changedCategory responses are per country; incomplete market-timing results are surfaced.

Platform restructure.

• changedThe application was split into the marketing site and the platform app, with new navigation.
• changedIntegrity constraints were added for datasets and datapoints; the marketing components and layout were refreshed.
