- interface -> router; symbol_utils -> symbols, which also takes safe_ticker_component
- utils is split: get_current_date to date_window, the HTTP helpers to net
- dataflows imports are absolute; the NoMarketDataError re-export from symbols is gone
- coverage and withholding notices named where a vendor's coverage starts or today's date
- the instrument context named today's date in every analyst prompt
- yfinance returned its errors as text, which the router counted as an answer, so the chain stopped and the text reached the analyst
- an empty result is checked against the vendor being reachable, so an outage is not reported as a company with no data
- a chain where every vendor is unavailable says so instead of ending the run
