CRYPTO-PDF-SECTION-FRESHNESS (Attached Date Recovery)

Release digest

CRYPTO-PDF-SECTION-FRESHNESS (Attached Date Recovery) — Crypto PDF reports now use section_freshness metadata for source citation and attachment-matrix freshness when source rows have labels but no row-level date. This reduces false missing-freshness gaps when the normalized project payload already carries real section-level update timestamps.

Added view-model and generated-PDF coverage for section-level freshness fallback, attached source-date copy, attachment-matrix missing-date counts, safe wording, and placeholder bans.
Updated the deterministic crypto PDF sample gate so the sample fixture validates section_freshness instead of relying only on row-level source dates.
Updated docs/architecture/CRYPTO_REPORTS.md and knowledge-base/docs/crypto/dashboard-ui.md because this improves visible PDF freshness labels without changing billing or report access behavior.
