plan_router.py – v0.13.1 (WP-15)
|
||
|
||
Minimal-CRUD + List/Filter für Templates & Pläne.
|
||
|
||
Änderungen ggü. v0.13.0
|
||
- Serverseitiger Zeitfenster-Filter über `created_at_ts` (FLOAT) bleibt erhalten.
|
||
- Lokaler Fallback-Zeitfilter wird DEAKTIVIERT, sobald ein serverseitiger Range aktiv ist
|
||
(verhindert false negatives).
|
||
- `plan_section_names` wird beim POST /plan materialisiert und für Filters genutzt.
