Technical evolution should leave a trail.
This changelog summarizes architectural and engineering milestones in CTG One’s professionalization. It does not replace Git history or document every commit; it identifies changes that materially affect platform capability, security, or verifiability.
Credibility hardening
Separated verified capabilities from roadmap claims and corrected outdated deployment/security narratives.
CTG One OS
Formalized the shared technology layer and maturity model across identity, data, transactions, automation, security and intelligence.
Products & case studies
Introduced evidence-based product case studies with CTG Craft Beer Investment as CASE-001.
AI architecture & governance
Defined AI boundaries, human-in-the-loop controls, evaluation requirements and promotion criteria.
Security, observability & testing
Added health checks, structured redacted logging, critical safety invariants, dependency audit thresholds and stronger headers.
Ecosystem technology mapping
Mapped each business unit to operating problems, CTG One OS modules and verified maturity states.
Public technical proof
Introduced public status, Labs framework and technical changelog as verifiable evidence surfaces.
Production readiness
Defined the Render deployment contract, health checks and production verification runbook.
AI platform architecture
Expanded CTG One AI with Citation-First RAG, agent runtime, risk tiers, evaluation, security and CTG Knowledge product architecture while retaining IN DEVELOPMENT status.
CTG Knowledge v0.1
Implemented the first authenticated RAG pilot with curated ingestion, pgvector retrieval, server-side model access, grounded answers and structured source metadata; production verification remains required before LIVE.
Changelog entries do not automatically make a capability LIVE. Technical status is published separately and requires sufficient evidence.
