UNIVERSE FM-1 bring-up branch, 2026-10-08.

The completed portable sound core in src/ and include/ is unchanged from
resonance-r1 (967bb5d18855baa1a393e8e4e687b729620d2120).

The target driver includes GPL-3.0-only Felucca HAL headers. isr.S adapts its
assembly wrapper, preserving copyright. This hardware integration is supplied
under GPL-3.0-only; a distributed combined firmware must satisfy that license.
COPYING.GPL-3.0 contains its full text. No compiled vendor runtime is distributed.

The build uses an external checkout and rejects a different commit or dirty HAL.

No bootloader, vendor firmware, updater, installable .fwsc or flash-writing
utility is included. Compiled test objects and the link probe are not firmware.
