Plugin Catalog
Stigmem plugins are optional Python packages discovered through the
stigmem.plugins entry point group. Installing a plugin package makes it
discoverable. Node behavior plugins still require the plugin's explicit
STIGMEM_*_ENABLED gate and a node restart; adapter packages require
host-application opt-in.
The eleven plugins below are independently versioned at 0.1.0 and support the
current alpha node line. The adapter-batch packages require
stigmem-node>=0.9.0a10,<1.0.0; earlier security plugins support the alpha
line they were published on. They remain experimental and opt-in.
