Full changelog

Bug Fixes

#238 — filing_search: company-name entity resolution (internal/search/edgar.go)
Queries like "Apple annual report 10-K" now resolve to the correct CIK via the SEC company_tickers.json map (stop-word stripping + exact title match + single-token prefix scan) instead of falling through to EFTS full-text search, which returned unrelated filings.

#239 — format_bibliography: DOI-to-metadata enrichment (internal/tools/bibliography.go)
When a source has a DOI but no title, the tool now performs an exact-entity ResolveByDOI lookup (first configured DOIResolver-capable AcademicProvider) before formatting, so citations are complete rather than reduced to bare URLs. Best-effort: a miss leaves the entry unchanged.

#236 — patent_search: enrichPatents 25 s aggregate deadline (internal/tools/patent.go)
Added context.WithTimeout(ctx, 25*time.Second) across the 3-concurrent goroutine fan-out. The 15 s per-fetch timeout still applies; the new aggregate cap prevents the semaphore stall that caused 40-60 s total latency when patents.google.com was slow.

All three fixes include new tests; go test -race ./... green.
