- vendors/yahoo: ohlcv (loader and cache), market (prices, indicators), fundamentals (profile, statements, insider), news, snapshot - vendors/alpha_vantage is a package; sec_edgar, fred, polymarket, reddit and stocktwits sit beside it - the one-method StockstatsUtils class is a function; the duplicate Yahoo host constant is gone - tests are named after the modules they cover: test_ohlcv_date_column, test_yahoo_snapshot, and the ohlcv and snapshot aliases

"""Symbol normalization must apply on every yfinance path, not just price fetch.
|
|
|
|
Regression tests for #983 (instrument identity), #984 (reflection returns), and
|
|
the news path: a broker symbol like XAUUSD must resolve to the same Yahoo symbol
|
|
(GC=F) that the price path uses, so identity, realized-return, and news lookups
|
|
hit the right instrument instead of failing/mismatching.
