The published image had no Xvnc/Xfce because nothing set the Dockerfile's
HERMES_BOT_DESKTOP argument, and a hosted instance (unprivileged, no sudo,
sealed /opt/hermes) cannot install at run time. The image layer is the only
delivery path.
- docker.yml: variant axis [slim, desktop]. :latest / :main / :v* stay the
image they are today; :latest-desktop / :main-desktop / :v*-desktop carry
the packages plus Playwright's headed Chromium. Slim owns the build cache
scope; one manifest per variant so a desktop publish failure never skips
slim's :latest.
- Dockerfile / stage2-hook.sh: XDG_RUNTIME_DIR=/tmp/hermes-runtime seeded
0700 as hermes (containers have no logind; the $HOME/.cache fallback was
the shared /opt/data volume), refused when foreign-owned; deterministic
Chromium discovery exporting the headless shell for ordinary browsing.
- bot_desktop: memory gate reads the cgroup working set (usage minus
inactive_file) so it cannot tighten over uptime and refuse to restart a
screen idle-stop just stopped; installable() gives three distinct dead-end
messages instead of a sudo line nobody there can run; env_for_agent
replaces a headless-shell pin so agent and dock share one Chromium.
Squash of IAvecilla/hermes-agent:bot-desktop-cloud-image (#112381, 13
commits), which GitHub auto-closed when its base branch merged as #108914.
Review fixes from pefontana (cache scope, per-variant merge, red browser
test) are included.
