Model Denmark's Dronebekendtgørelsen § 5 (on top of EU 2019/947) across all
three tiers: schema, API Server, and Web App.
Schema (migration 1720300700_add_logbook.js): two collections — `drones`
(classification inputs: mtom, is_toy, autologs, c_class, operator no.) and
`flights` (§5 minimum content + category/purpose/logging-path + operational
maturity + a retention_until computed as operation_date + 5y). Locked API
rules; access flows through the service account like users/orgs.
API Server (logbook.go, logbook_export.go): /api/drones and /api/flights CRUD
with per-role scoping in Go (user→own, admin→org, superadmin→all), plus
GET /api/logbook/export (CSV — the "readable electronic format" for
Trafikstyrelsen / pending police disclosure). Compliance is computed
server-side per flight: exemption (toy / club-area / <250 g hobby), effective
logging path, and red flags (autologs-without-FDR, specific-category-without-
authorisation, missing §5 fields, past retention). Manual-path saves missing a
§5 field are blocked (422).
Web App: BFF proxies (export preserves the CSV Content-Type/Disposition),
api.js client fns, and a Logbook.vue view (Flights/Drones tabs, inline forms,
compliance badges + expandable detail, Export CSV) wired into Dashboard.vue,
replacing the placeholder. Includes the rebuilt embedded dist bundle.
