## Engine and distribution boundary

Godot is a separately licensed engine (MIT), with its own third-party
components. Android templates must be built from the corresponding Godot
sources for the F-Droid workflow. The engine's notices remain applicable:

Local build outputs, template APKs, research backups and unreferenced
promotional images are excluded from game exports. Unclear provenance of any
such local artifacts is recorded in the refactor report; no license is
invented for them.
