The changelog still described unreleased work under 1.1.0, which was already
published with its own notes. Those notes are restored verbatim for history,
and the new work has its own 1.2.0 section that the feed publisher will turn
into release notes.
The release guide, infrastructure map, and mobile SSOT now carry the 1.2.0
identity, state that installer binaries are distributed through the feed and
never committed, and record that the published 1.1.0 installer is unsigned and
is being superseded rather than rewritten. Backlog entries cover the remaining
external signing and token secrets.
Release notes for 1.1.0 were split between an Unreleased section and the
version section, so the published notes would have omitted the update-feed
and desktop changes. Everything shipping in this version now sits under one
`## [1.1.0]` heading.
`docs/map/` becomes the entry point for what infrastructure exists per
platform and how far each feature is developed, with a documented update
protocol so feature work and this map do not drift apart again. The release
guide now states that installer binaries live in the update feed rather than
the repository.
