/**
 * Adapter to the time tracking model of lane L12 (read-only use in planning).
 *
 * L12 adds `TimeEntry.source` (tracked | manual), `TimeEntry.approvalStatus` (approved | pending |
 * rejected) and `WorkSession.manual`. Planning rules:
 * - live situation / delay evaluation: only `source = tracked` entries of non-manual sessions,
 * - actual duration of completed orders: only `approvalStatus = approved` entries.
 * The filters are enabled automatically as soon as the generated Prisma client knows the fields
 * (after the L12 merge); before that they are no-ops, so this lane compiles against both schemas.
