CRYPTO-HISTORY-READINESS-DIAGNOSTICS (Report QA)

Release digest

CRYPTO-HISTORY-READINESS-DIAGNOSTICS (Report QA) — Crypto history readiness manifests now expose raw history rows seen, rows missing snapshot dates, snapshot date range, attached report-context fields, and missing report-context fields.
History rows without snapshot_date or date no longer count as attached snapshots for trend or delta readiness, preventing undated rows from masking report history-storage gaps.

Added focused coverage for undated history rows and updated the history readiness contract tests for the richer diagnostic manifest.
Updated docs/architecture/CRYPTO_REPORTS.md and docs/reports/audits/2026-06-01_CRYPTO_REPORT_DATA_GAP_ANALYSIS.md. Public docs decision: no public documentation update is required because this is an internal report-history QA/data-pipeline gate and does not change visible report copy, billing, scoring, audit coverage, legal claims, or investment guidance.
