- GPM channel is system.yaml gpm.releases (testing->stable), not GRAV_CHANNEL
- core upgrade is 'bin/gpm self-upgrade -y'; existing remote-upgrade-grav
target ('bin/grav upgrade') is broken and must be fixed
- add server content-pull + cache-clear + preflight steps to Phase 2

Coordinated upgrade of core rc.10 -> 2.0.4 and promotion of
admin2/api/flex-objects to GPM management (option B). Documents the
dependency-forced atomicity, the three plugin-management categories,
git-sync handling (disable-during-upgrade, remote-only), and the
local -> test -> prod(documented-only) rollout.
