+# Node.js End-of-Life Strategy
+
+## Overview
+
+This document defines the strategy for managing Node.js runtime versions in the **game** project, ensuring we stay on actively maintained releases and plan upgrades proactively. All version decisions align with the [Hack23 ISMS Secure Development Policy](https://github.com/Hack23/ISMS-PUBLIC).
+
+---
+
+## Current Status (March 2026)
+
+| Node.js | Release Date | Status | Bug Fixes Until | Security Fixes Until |
+|---------|-------------|--------|-----------------|----------------------|
+| **25 (Current)** | Oct 15, 2025 | ✅ **Active — in use** | Apr 1, 2026 | Jun 1, 2026 |
+| 24 (LTS – Krypton) | May 2025 | Active LTS | Oct 2026 | Apr 28, 2028 |
+| 22 (LTS – Jod) | Apr 2024 | Maintenance | Oct 2025 | Apr 30, 2027 |
+| 20 (LTS – Iron) | Apr 2023 | Maintenance | Oct 2024 | Apr 30, 2026 |
+
+> **Note:** Node.js 25 is an odd-numbered "Current" release, meaning it does **not** receive LTS status. It is supported for approximately 6 months before reaching end-of-life. We use it to validate readiness for Node.js 26.
+
+---
+
+## Node.js Release Cadence
+
+The OpenJS Foundation follows a predictable release schedule:
+
+- **Every April** — A new **even-numbered** major version is published as "Current"; odd-numbered Current versions reach EOL
+- **Every October** — The April even-numbered release graduates to "Active LTS", and a new odd-numbered major is published as "Current"
+- **Active LTS** lasts 12 months; **Maintenance LTS** lasts an additional 18 months
+
+```
+Version  | Release   | Current  | Active LTS    | Maintenance LTS | EOL
+---------|-----------|----------|---------------|-----------------|----------
+Node 20  | Apr 2023  | ~6 mo    | Oct 2023      | Oct 2024        | Apr 2026
+Node 22  | Apr 2024  | ~6 mo    | Oct 2024      | Oct 2025        | Apr 2027
+Node 24  | May 2025  | ~6 mo    | Oct 2025      | Oct 2026        | Apr 2028
+Node 25  | Oct 2025  | ~6 mo    | N/A (odd)     | N/A             | Jun 2026
+Node 26  | Apr 2026  | ~6 mo    | Oct 2026      | Oct 2027        | Apr 2029
+Node 27  | Oct 2026  | ~6 mo    | N/A (odd)     | N/A             | Jun 2027
+Node 28  | Apr 2027  | ~6 mo    | Oct 2027      | Oct 2028        | Apr 2030
+```
+
+---
+
+## Version Upgrade Policy
+
+### Principles
+
+1. **Never run end-of-life Node.js in CI/CD or production** — upgrade within 30 days of EOL.
+2. **Track even-numbered LTS releases for stability** — use Current (odd) releases for forward compatibility testing.
+3. **Upgrade CI/CD and dev containers together** — single PR, all-or-nothing.
+4. **Test on the next version before it is released** — reduce upgrade friction.
+
+### Upgrade Triggers
+
+| Trigger | Action | Timeline |
+|---------|--------|----------|
+| New major version release | Update `test-and-report-latest-node.yml` to new version | Within 1 week of release |
+| Current version reaches EOL | Upgrade all workflows to next version | Before EOL date |
+| LTS version graduates | Evaluate adoption for main workflow | Within 2 weeks |
+| Security advisory | Apply patch or upgrade immediately | Within 24 hours |
+
+---
+
+## Upcoming Milestones
+
+### ⚠️ Immediate — Node.js 25 End of Bug Fixes: April 1, 2026
+
+Node.js 25 receives its final bug-fix release around **April 1, 2026**. Security-only patches continue until **June 1, 2026**.
+
+Action required: Upgrade all CI/CD workflows to Node.js 26 immediately after its release in April 2026. See [FUTURE_WORKFLOWS.md](./FUTURE_WORKFLOWS.md) for the detailed upgrade plan.
+
+### 🔜 Upcoming — Node.js 26 Release: April 2026
+
+Node.js 26 is expected in **April 2026**. It will:
+
+- Enter "Current" status immediately upon release
+- Graduate to **Active LTS in October 2026**
+- Be maintained (Active + Maintenance) until **April 2029**
+
+**Planned upgrade:** Within **2 weeks** of the Node.js 26 release. See [FUTURE_WORKFLOWS.md](./FUTURE_WORKFLOWS.md).
+
+### 📅 Future — Node.js 26 Active LTS: October 2026
+
+When Node.js 26 enters Active LTS, it becomes the recommended production runtime. At this point:
+
+- Node.js 24 transitions from Active LTS to Maintenance LTS
+- The primary workflow (`test-and-report.yml`) should target Node.js 26
+
+### 📅 Future — Node.js 24 EOL: April 2028
+
+Node.js 24 reaches end-of-life in April 2028. By this date, all workflows and devcontainers must have moved to Node.js 26 or later.
+
+---
+
+## Version Matrix
+
+The project maintains two parallel test workflows:
+
+| Workflow | Purpose | Current Node Version |
+|----------|---------|----------------------|
+| `test-and-report.yml` | Primary CI — stable, production-ready | **25** |
+| `test-and-report-latest-node.yml` | Forward-compat — tests next version | **25** (will become 26) |
+
+When a new Node.js version is released:
+1. Update `test-and-report-latest-node.yml` to the new version first
+2. Once validated (typically within the same sprint), update `test-and-report.yml`
+3. Update all other workflows (`release.yml`, `codeql.yml`, copilot setup) together
+
+---
+
+## Risk Assessment
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| Security vulnerability in EOL Node.js | High (after EOL) | Critical | Upgrade before EOL |
+| Incompatible npm packages | Medium | High | Run tests on new version early |
+| Breaking API changes | Low | High | Test on Current release before it becomes primary |
+| CI/CD downtime during upgrade | Low | Medium | Upgrade in dedicated PR with rollback plan |
