Changelog - Analytics Module

All notable changes to the analytics module are documented here. The format is based on Keep a Changelog.

[Unreleased]

Changed

• Security hardening (2026-08-19): ModelServingEngine::loadModel now supports explicit SHA-256 integrity verification and optional fail-closed enforcement via ModelServingConfig::require_model_integrity.
• Security hardening (2026-08-19): TFServingConfig switched to secure defaults (https://, verify_ssl=true) and blocks plaintext HTTP unless allow_insecure_transport=true is explicitly configured.
• Reliability hardening (2026-08-19): LLMProcessAnalyzer::validateResponse now enforces stricter schema/type/range checks and bounded payload limits for fraud, 5R, and prediction tasks.
• Test coverage extended for integrity verification, insecure transport gating, and strict LLM response validation behavior.
• Module documentation synchronized and validated (2026-07-19): All roadmap artifacts, future enhancements, and API documentation aligned to source-verifiable module behavior.
• Documentation governance: ROADMAP.md, FUTURE_ENHANCEMENTS.md, README.md, ARCHITECTURE.md, SECURITY.md, PRODUCTION_REQUIREMENTS.md, and CHANGELOG.md all updated with current validation date.
• Added MODULE_EVIDENCE.md to document build/test evidence and closure criteria verification.
• Doxygen API documentation verified: 100% coverage across 24 analytics headers; all public APIs documented with @brief, @param, @return, and @code examples.
• Production readiness checklist: All core runtime surfaces and security/failure behavior documented at module level.
