Changelog

Dual-audience hero, /pricing, /use-cases, and /chains/[coin] programmatic SEO across all 11 chains. About, API docs, changelog, and contact rewritten against the product roadmap.

Migrated mugenlink_userdata to the dedicated user-data-pg cluster. Alembic head 021, 30 tables under row-level security, six application roles separated by least privilege.

Snowflake queries now run behind a circuit breaker (5-failure trip, 60s recovery). Read-only endpoints route to a Postgres read replica when configured. Tiered rate-limit keys (API key → user → IP) prevent NAT collisions.

10 products spanning Phase 1 and Phase 2. Plans vaulted with delivery maps and dependency graphs.

Retired RSA/JWT keypair authentication. All 12 service users moved to programmatic access tokens with least-privilege role bindings. Account migrated to FWPGNQM-WTB81124 in us-west-2.

Cross-pod cache keys switched to blake2b. 12 audit findings closed. 148/148 unit tests pass; structured JSON output remains the canonical format.

End-to-end load completed for both sources: 96 Blockchair files across 6 UTXO chains and 29 3xpl files across all 11 chains. Landing prefixes finalized and locked in the registry.

Bronze → Silver → Gold model layers per chain, 220+ models in production. Per-coin templates fan out from a single staging contract; incremental materialization is the default.

Established a 45.3k token baseline for the dashboard build context. Used to gate any change that materially expands the loaded code surface.

6-month delivery plan committed. Defines the product surface, model layer, and tier structure that the May roadmap formalized.
