app/core/chunk_payload.py — Mindnet V2 (compat)
|
||||
|
||||
Ziele (ohne Bruch zur lauffähigen v1-Basis):
|
||||
- Akzeptiert `file_path=` (Alias zu path_arg)
|
||||
- Verarbeitet Chunks sowohl als `dict` **als auch** als Objekt (z. B. Dataclass `Chunk`)
|
||||
- Schreibt v1-kompatible Felder:
|
||||
* `id` (Alias von `chunk_id` – **wichtig** für app/core/edges.py v1)
|
||||
* `neighbors: {prev, next}` wird **berechnet** (Sequenz), falls nicht vorhanden
|
||||
- Denormalisiert optional `tags` der Note auf Chunks
|
||||
- Fügt Nummern-Aliase hinzu: `ord`, `chunk_num`, `Chunk_Nummer`
|
||||
Ziele (unveränderte v1-Basis, weniger Duplikate):
|
||||
- **Kanonicum:** `index`
|
||||
- **Standard‑Alias (v2):** `ord` (abschaltbar über ENV MINDNET_CHUNK_INCLUDE_ORD=0)
|
||||
- **Optionale Aliase:** gesteuert über ENV MINDNET_CHUNK_INDEX_ALIASES
|
||||
(z. B. "chunk_num,Chunk_Nummer" oder "Chunk_Number"). Standard: kein zusätzlicher Alias.
|
||||
- Verarbeitet Chunks als Dict **oder** Objekt (Dataclass) und setzt immer `id` (= `chunk_id`)
|
||||
- Berechnet `neighbors.prev/next`, falls nicht vorhanden
|
||||
- Denormalisiert Note‑`tags` auf Chunks
|
||||
- Akzeptiert `file_path=` als Alias zu `path_arg`
|
||||
|
||||
Wichtig:
|
||||
- `edge_defaults` gehören zur *Note* (Typ-Regeln), nicht pro Chunk. Werden hier **nicht** gespiegelt.
|
||||
ENV:
|
||||
- MINDNET_CHUNK_INCLUDE_ORD: "1" (Default) | "0"
|
||||
- MINDNET_CHUNK_INDEX_ALIASES: CSV‑Liste zulässiger Namen: chunk_num,Chunk_Nummer,Chunk_Number
|
||||
|
||||
Hinweis: `edge_defaults` sind Note‑Regeln (nicht pro Chunk).
