Zweck
|
|
-----
|
|
Erzeugt ein robustes Note-Payload. Werte wie `retriever_weight`, `chunk_profile`
|
|
und `edge_defaults` werden in folgender Priorität bestimmt:
|
|
1) Frontmatter (Note)
|
|
2) Typ-Registry (config/types.yaml: types.<type>.*)
|
|
3) Registry-Defaults (config/types.yaml: defaults.*)
|
|
4) ENV-Defaults (MINDNET_DEFAULT_RETRIEVER_WEIGHT / MINDNET_DEFAULT_CHUNK_PROFILE)
