CRYPTO-PDF-REGRESSION-SAMPLE-QA (Realistic Report Artifacts) & CRYPTO-PDF-FILE-CONTRACT (Downloaded Report QA)

Release digest

CRYPTO-PDF-REGRESSION-SAMPLE-QA (Realistic Report Artifacts) — Added a crypto PDF regression sample gate that generates local intelligence/classic PDFs for realistic fixture shapes, including live-token, tokenless, thin-data, and security-rich pre-launch reports.
CRYPTO-PDF-FILE-CONTRACT (Downloaded Report QA) — Added a local verifier for downloaded crypto PDFs so production files can be checked for required sections, legal-safe copy, template mode, and prohibited placeholder text.
CRYPTO-REPORT-DOWNLOAD-PREVIEW (Export Boundary Copy) — The crypto report download menu now previews newer PDF sections such as completeness verdict, source confidence, and evidence action plan before export.

Added regression-sample script coverage and wired the sample generator into the local pre-push crypto PDF gate.
Updated frontend/e2e contracts so the download menu keeps the current report boundary visible before PDF generation.
Updated docs/architecture/CRYPTO_REPORTS.md and knowledge-base/docs/crypto/dashboard-ui.md because this changes local PDF QA workflow and visible download-menu copy. Public-docs decision: documented only as export-boundary preview and evidence notes, without audit, safety, legal, or investment claims.
