## Product license

FTW code uses AGPL-3.0-only with the narrow Energyplan combination permission.
Commercial FTW use is allowed under the AGPL terms. The proprietary Energyplan
worker is free for private household use; commercial worker use, bundling and
paid services require a separate written Sourceful license. Keep product copy
consistent with [LICENSING.md](LICENSING.md), which also explains the separate
rights in website artwork and brands.

P1 Badge Limit the commercial restriction to newly licensed workers

For organizations using an Energyplan worker released before this license transition, this says that all commercial Energyplan use requires a new Sourceful license, even though LICENSING.md explicitly preserves earlier versions' earlier grants. Scope this restriction to worker versions distributed under the new Home Use terms so existing commercial license rights are not misrepresented.
