"""Scheduled task: pull СберИндекс city-level secondary-housing price index (#887).
|
|
|
|
Delegates HTTP fetch + upsert to app.services.sber_index.pull_sber_indices().
|
|
Wired into the in-app scheduler as source='sber_index_pull'. Triggered monthly via
|
|
the scrape_schedules seed (migration 093).
|
|
|
|
Three dashboards fetched per configured city:
|
|
- real_estate_deals (hedonic sold-price index)
|
|
- residential_real_estate_prices (repeat-sales hedonic)
|
|
- dinamika-tsen-obyavlenii (asking-price benchmark)
|
|
|
|
NOTE: estimator time-adjust wire (step 4, #887) is OUT OF SCOPE for this module.
|
|
That is a client-visible change requiring a backtest gate — see issue #887 step 4
|
|
and the follow-up note in app/services/sber_index.py.
