The sidecar source ships inside the installed plugin tree (``plugins/platforms/photon/sidecar/``). On dev/source installs that tree is writable and everything — ``npm ci``, the spectrum patch, the sidecar itself — happens in place. Hosted/managed images instead keep the whole install tree under an immutable ``/opt/hermes`` (read-only for the hermes user), which broke every install/self-heal path with EROFS (NS-606). Resolution order (mirrors ``resolve_whatsapp_bridge_dir`` for the Baileys bridge, which hit the same wall): 1. ``PHOTON_SIDECAR_DIR`` env override — operator escape hatch, used as-is. 2. Source dir writable → run in place (dev installs, unchanged behavior). 3. Source dir read-only but ``node_modules`` is baked and current → run in place. This is the managed-image happy path: the Dockerfile bakes the sidecar deps with ``npm ci`` at build time (deterministic installs, NS-559), so no runtime install is ever needed. 4. Source dir read-only and deps missing or stale → mirror the sidecar source files to ``$HERMES_HOME/photon/sidecar`` (the durable data volume, e.g. ``/opt/data`` on hosted) and return that. The caller's normal install/self-heal machinery then works there because it is writable. The mirror is refreshed on every resolve: when an image update changes a sidecar source file, the changed file is re-copied (content compare, not mtime) while ``node_modules`` is left in place — the adapter's existing lockfile-vs-install-marker staleness check then triggers the ``npm ci`` self-heal inside the mirror. This module is import-light on purpose: both ``adapter.py`` (gateway) and ``cli.py`` (``hermes photon ...``) use it. ) annotationsN)Path)Optionalsidecar)z index.mjsz package.jsonpackage-lock.jsonz$patch-spectrum-mixed-attachments.mjspathrreturnboolc|dz } ||dS#t$rYdSwxYw)zTrue when we can create files in ``path`` (probe-based, not stat).
