- inline _in_news_window, a trivial passthrough left from extracting
dataflows.date_window.in_window; call in_window directly
- drop SignalProcessor's orphaned quick_thinking_llm attribute (unused since
rating extraction became a deterministic parse)
- the upper bound was inclusive, so an article stamped exactly midnight after
end_date leaked into a historical run
- flat epoch timestamps were parsed in host-local time and offset-aware stamps had
tzinfo stripped without converting, making filtering machine-dependent
- normalize every operand to UTC and use a half-open [start, end + 1 day) #1126
Clear the deferred full-repo lint backlog so the whole tree passes the strict
ruff select (E,W,F,I,B,UP,C4,SIM). Mechanical fixes dominate: import sorting,
pep585/604 annotations, dropped dead imports, and whitespace. The few semantic
changes are behavior-preserving: declare __all__ on the agent_utils and
alpha_vantage re-export hubs; expand 'from x import *' to explicit names; use
immutable tuple defaults instead of mutable list defaults; contextlib.suppress
for try/except/pass; and narrow an over-broad assertRaises.
The yfinance news date filter only ran when an article had a parsed date, so
flat-format and undated articles bypassed it and leaked future news into
historical/backtest runs. Parse the flat providerPublishTime, apply one
look-ahead-safe window rule across ticker and global news (undated kept only
when the window reaches the present), and return an informative message when
everything is filtered out.
