CRYPTO-SNAPSHOT-NORMALIZED-CONTEXT-PERSISTENCE (Report QA)

Release digest

CRYPTO-SNAPSHOT-NORMALIZED-CONTEXT-PERSISTENCE (Report QA) — Daily crypto BigQuery snapshot rows now prefer normalized, merged report-facing context over stale shallow canonical fields before serializing historical security_evidence, contract_addresses, source_links, and admin_controls.
Snapshot export still falls back to attached raw report-context fields when normalization leaves a field empty, and preserves raw section_freshness dates when the normalized shell lacks freshness timestamps.

Added focused daily snapshot coverage proving canonical and wrapper evidence are merged into stable history JSON without leaking raw wrapper keys or dropping existing canonical context.
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 snapshot/history persistence contract and does not change visible report claims, billing, scoring, audit coverage, legal claims, or investment guidance.
