🔁 Technology Lifecycle Declaration (TLD)¶

This document declares the technology stack and runtime versions used by this component, aligned with https://endoflife.date.

Its purpose is to: - Track End-of-Life (EOL) risks - Enable proactive upgrades - Support security and compliance audits - Enable automation and validation in CI/CD pipelines

🖥️ Infrastructure Runtime & Technology Lifecycle¶

All components are deployed using Docker containers on Azure App Service (PaaS). This matrix declares the runtime, base code, and framework lifecycle for each workload.

🚫 New developments MUST NOT use EOL or near-EOL components.

🚨 Lifecycle Enforcement Rules¶

❌ EOL components MUST NOT be deployed
⚠️ Components within 6 months of EOL require an upgrade plan
✅ LTS versions are mandatory for new developments
🔁 Lifecycle review is required on every release
