Full changelog

✨ Research Capability Expansion

This release adds three new structured-research domains, two cross-cutting result-quality signals, and two search lenses — all behind the proven capability-interface pattern, all additive.

New structured-domain tools

filing_search (#51) — search SEC EDGAR for US public-company filings (10-K, 10-Q, 8-K, S-1, DEF 14A, …) by company, ticker, or CIK; or full-text search across all filers. Set facts=true for structured XBRL company facts (revenue, net income, EPS, assets) passed through exactly as filed. No API key — just a contact email (EDGAR_CONTACT_EMAIL, falls back to OPENALEX_EMAIL).
legal_search (#52) — search US federal and state court opinions via CourtListener, with Bluebook citations, jurisdiction and date filters. Works keyless; COURTLISTENER_API_TOKEN raises the rate limit.
econ_search (#82) — look up FRED macroeconomic data (800K+ series: GDP, CPI, unemployment, rates). Keyword-search series or pull observations by series_id, with units/frequency/date transforms. Values verbatim, no rounding. Set FRED_API_KEY (free).

Smarter results everywhere

Typed source classification (#62) — scrape_page and search_and_scrape now tag every source with sourceType (peer_reviewed / official_docs / government / news / blog / forum / wiki / social_media / unknown), authorityTier (high/medium/low), and domainCategory, so your AI can hedge by source quality. Driven by Schema.org / Highwire metadata where available.
Claim evidence (#66) — pass an optional claim to web_search or search_and_scrape and each result surfaces the most claim-relevant sentence(s). Evidence only — the server never decides supports/contradicts; your AI makes the call.

New lenses

devops — Kubernetes, Docker, Terraform, cloud, CI/CD docs.
academic-extended — preprint servers, OA aggregators, and repositories beyond core journal indexes.
