CRYPTO-HISTORY-REVIEWER-EVIDENCE-SNAPSHOTS (Report Logic)

Release digest

CRYPTO-HISTORY-REVIEWER-EVIDENCE-SNAPSHOTS (Report Logic) — Daily BigQuery crypto snapshots can now preserve nullable reviewer-readiness context for security_evidence, contract_addresses, source_links, and admin_controls alongside the existing stage, coverage, source-family, and surface-contract report context.

Added focused coverage proving the snapshot schema migrates older tables with the new nullable JSON fields, the daily snapshot writer serializes attached reviewer evidence without inventing missing values, the history reader decodes those fields back into report payloads, and the PDF view model can use historical security evidence for safe security-provenance delta copy.
Updated docs/architecture/CRYPTO_REPORTS.md and docs/reports/audits/2026-06-01_CRYPTO_REPORT_DATA_GAP_ANALYSIS.md because this expands the internal crypto history snapshot contract. Public docs decision: no public documentation change is required because this changes historical storage/report context only; it does not change visible PDF copy, billing, audit coverage, legal claims, safety language, or investment guidance.
