The previous topology bind-mounted the entire `~/.claude/plugins/`
directory from host. That brought through plugins, marketplaces, and
extracted cache content correctly — but ALSO brought through the
registry JSONs (`known_marketplaces.json`, `installed_plugins.json`,
`plugin-catalog-cache.json`) which carry absolute OS-native paths:
"installLocation": "C:\Users\gergo\.claude\plugins\marketplaces\X"
"installPath": "C:\Users\gergo\.claude\plugins\cache\Y\Z"
Claude in the Linux container fails to resolve these Windows paths and
reports `Marketplace X failed to load: cache-miss`.
Split the topology:
- `plugins/marketplaces/` (git clones) and `plugins/cache/` (extracted
plugin files) stay bidirectional RW binds — content is path-independent.
- Registry JSONs move into the per-container named volume. post-create.sh
reads host's versions, rewrites any absolute path ending in
`/.claude/plugins/<rest>` (Windows `C:\Users\...` and POSIX
`/Users/...` / `/home/...` patterns) to `/home/node/.claude/plugins/<rest>`,
and writes the translated result to the volume.
What this gets you:
- Plugin installed on host → next container rebuild has it (translated).
- Plugin installed inside container → lives in volume registry; lost on
rebuild (consistent with credentials model). Re-install on host for
persistence.
ensure-host-config-dirs.cjs now also creates `plugins/marketplaces/` and
`plugins/cache/` on host if absent (Docker rejects bind mounts whose
source doesn't exist).
