Earnings calendar and EPS history
---------------------------------
This application ingests the earnings calendar and EPS surprise history from the
public DoltHub repository:

Use in this project: private, internal ingestion only. The data is normalized
into PostgreSQL (`earnings_events`) — the announcement calendar is aligned to the
EPS history via a minimum-cost monotonic pairing, symbols are normalized, and the
session field is mapped to bmo/amc/unknown. No public API, bulk export, or
redistribution of the data is provided. This attribution and the upstream license
are preserved per the CC BY-SA 4.0 terms. Re-review licensing before any public
or commercial access.

The post-no-preference/stocks repository (workstream B) is not used at this time
and would be reviewed separately.
