# Riff — current documentation

**Riff 1.1.0 FINAL is the current signed release edition.** It is installed on HU; the phone retains
the previously installed 1.1.0 RC. [Release status](/Riff/1-1-0/status) identifies exact artifacts,
verification and remaining acceptance. The public website now distributes the same 1.1.0 FINAL APK
with a matching clean source snapshot.

The [requirements registry](/Riff/LATEST/requirements) routes normative ownership.
[Current delivery](/Riff/LATEST/tldr) and [verification handoff](/Riff/LATEST/worklog) report actual
implementation and evidence.
