"""Curator snapshot + rollback.
Before any mutating curator pass, ``~/.hermes/skills/`` is tar.gz'd under
``~/.hermes/skills/.curator_backups/<utc-iso>/`` with a ``manifest.json``.
Rollback first snapshots the CURRENT tree (so it is itself undoable), then
extracts the chosen snapshot into place.
Excluded: ``.curator_backups/`` (would recurse), ``.hub/`` (hub-managed) and
``.git/`` (repository metadata — managed by git, not the curator).
Included: every skill dir, ``.usage.json``, ``.archive/``, ``.curator_state``
(so rollback also restores last-run-at and the curator doesn't re-fire),
``.bundled_manifest`` and ``.curator_suppressed``.
Each snapshot also copies ``~/.hermes/cron/jobs.json`` as ``cron-jobs.json``:
the consolidation pass rewrites cron ``skills``/``skill`` references in place,

"""Curator snapshot + rollback. Before any mutating curator pass, ``~/.hermes/skills/`` is tar.gz'd under
``~/.hermes/skills/.curator_backups/<utc-iso>/`` with a ``manifest.json``. Rollback first snapshots the CURRENT tree (so it is
itself undoable), then extracts the chosen snapshot into place. Excluded: ``.curator_backups/``, ``.hub/`` (hub-managed), ``.git/``.
Included: skill dirs, ``.usage.json``, ``.archive/``, ``.curator_state`` (so rollback also restores last-run-at and the curator
doesn't re-fire), ``.bundled_manifest``, ``.curator_suppressed``. Each snapshot also copies ``~/.hermes/cron/jobs.json`` as

Two modes:
native — attach images as OpenAI-style ``image_url`` content parts on the
user turn; provider adapters translate these to vendor formats.
text — run ``vision_analyze`` on each image up-front and prepend the
(lossy) description to the user's text. Still the right choice
for non-vision models.
:func:`decide_image_input_mode` decides once per message turn from
``agent.image_input_mode`` (``auto`` | ``native`` | ``text``, default ``auto``)
plus the active model's capability metadata. In ``auto`` mode:
- An explicitly configured ``auxiliary.vision`` backend is the DE-FACTO route
(``text``): a user who named a dedicated vision model wants it used even
when the main model has native vision. ``image_input_mode: native`` is the
absolute override.
- Otherwise, ``supports_vision=True`` (config override or catalog) → native.
- Otherwise text via the default vision_analyze flow.
``vision_analyze`` stays surfaced as a tool in every session so skills that
chain it keep working; routing only affects how *user-attached images on the
current turn* are presented to the main model.
``native`` attaches images as OpenAI-style ``image_url`` parts; ``text`` runs
``vision_analyze`` up-front and prepends the lossy description (right for
non-vision models). :func:`decide_image_input_mode` picks once per turn from
``agent.image_input_mode`` (``auto`` | ``native`` | ``text``): in ``auto`` an
explicit ``auxiliary.vision`` backend forces ``text`` even for vision-capable
main models (``native`` is the absolute override); else ``supports_vision``
(config override or catalog) decides. ``vision_analyze`` stays a tool regardless.
