/api/service/tools/* was a second implementation of the OSM geocoding and taxi
routing the Python backend already owns — its own Overpass client, alias
matching and scoring. It drifted: it still asked Overpass for `out center tags`,
so a runway resolved to the middle of the strip rather than a threshold, which
is the runway-endpoint bug the backend fixed. Teaching the copy about runway
endpoints would mean maintaining the geometry twice, so the copy goes instead.
Forwarding exposes origin_runway_point / dest_runway_point and
include_connectors, and inherits the backend's Overpass cache and its radius
fallback for aerodromes with no generated OSM area (EDDM), which the copy
answered with an empty feature list. Failures now carry an HTTP status as well
as the error code in the body; the old copy answered every error with 200.
The frequencies call sites needed real types: airportGeocode.ts sat under
server/api with no default export, so Nitro registered it as a route whose
return type collapsed to any and poisoned the whole API type map. The typecheck
was green because of it, not despite it.

Usage tracking:
- new UsageEvent collection records every STT/TTS/LLM call per user with
provider, model, volume (audio seconds, characters, tokens) and an
estimated USD cost; self-hosted providers (Speaches/Piper) and cache
hits record at $0
- pricing table for whisper-1, tts-1, gpt-5-nano & co. in server/utils/usage.ts
- weekly KPI mail gains an "AI-Nutzung & Kosten" section: weekly and
rolling 30-day cost, per-kind breakdown, top 5 users by cost
- quota alert mail when rolling 30-day cost exceeds USAGE_ALERT_USD
(default $5), at most once per calendar month (UsageAlertDelivery)
Hardening:
- /api/atc/say now requires an authenticated session (middleware
exemption removed); useFlightLabAudio sends the bearer token
- /api/service/tools/latency requires auth (was a public LLM endpoint)
- per-user rate limits: PTT 20/min, say 60/min, latency 5/min
- cron endpoints (waitlist-drip, weekly-kpi-report) require a shared
secret via ?secret= or x-cron-secret (CRON_SECRET, falls back to
KPI_CRON_SECRET); allowed with a warning while unset so existing
deployments keep working
- PTT records the actual transcribed audio duration for billing accuracy
