-Background (shared-$HERMES_HOME bug)
-------------------------------------
-$HERMES_HOME (/opt/data) is a DATA volume that users commonly bind-mount from
-the host (``~/.hermes:/opt/data``) and sometimes share with a host-side
-Desktop/CLI install. Older images wrote ``printf 'docker' > $HERMES_HOME/.install_method``

-inside the Docker container").
-
-The fix scopes the stamp to the install tree (baked at
-``/opt/hermes/.install_method`` in the Dockerfile, read first by
-``detect_install_method``). stage2 must therefore:
-
-  * NOT write the 'docker' stamp into $HERMES_HOME any more, and
-  * proactively remove a stale 'docker' stamp from $HERMES_HOME so homes

-"""Contract test: the s6-overlay stage2 hook and main-wrapper reject an
-unsupported `docker run --user <arbitrary-uid>:<gid>` start with actionable
-guidance, while still allowing:
-
-  - root start (id -u == 0)
-  - `--user <hermes-uid>` (the supported non-root start, #34648 / #34837)
-
-Background: in the tini era `docker run --user $(id -u):$(id -g)` was used to
-make container-written files match the host user. Under s6-overlay this can't
-work — the bootstrap (UID remap, volume/build-tree chown, config seeding) needs
-root, and the baked image dirs are owned by the hermes build UID, so an
-arbitrary pinned UID can't write them (EACCES on a bind mount, hard crash on a
-named volume). The supported path is root start + HERMES_UID/HERMES_GID (or the
-PUID/PGID aliases), which remaps the hermes user and chowns the volume.
-
-The guard fires only when the current UID is neither root NOR the hermes UID,
-so the #34648 `--user 10000:10000` case (pinning to the hermes UID itself) is
-unaffected.
