[0.2.4] - 2026-06-18

Added

• patent_filings_by_ticker tool — USPTO granted patents mapped to a single ticker by corporate assignee (patent ID, grant date, title, type, claims, citations, CPC classification, inventors, filing-to-grant time)
• screener_patent_filings tool — cross-ticker patent filings screening with summary stats (total patents, total tickers, top CPC sections)
• Integration tests for patent filings (ticker, screener, and tool-level round-trip)

Fixed

• Screener summary block is now populated for screener_government_contracts (regression since 0.2.3) and screener_reddit_mentions (since 0.2.2) — both previously returned all-null summary fields because the SDK unwraps screener responses down to the rows and discards the summary. The adapter now fetches the full envelope so the backend-computed summary is preserved.

Changed

• Bumped finbrain-python dependency from >=0.2.3 to >=0.2.5 (required for patent filings endpoints)
• FBClient now caches the underlying finbrain-python client per API key, so repeated tool calls reuse a single HTTP session/connection pool instead of opening a new one each call
• Strengthened screener integration tests to assert summary values (not just key presence), which is what previously masked the empty-summary bug
• Internal cleanup: removed the unused _make_client helper from the server entrypoint, documented latest_slice's chronological-ordering assumption, and corrected README inaccuracies (a non-existent settings.py in the project tree and the API-key configuration note)
