Canonical Version Registry (Snapshot)

As established in Phase 4:

Core Infrastructure

Package	Version	Status
Node.js	24.13.0	Canonical
npm	11.7.0	Canonical
TypeScript	5.9.3	Canonical
Prisma	7.2.0	Canonical

Frontend Frameworks

Package	Version	Notes
React	19.2.3 (primary), 18.3.1 (secondary)	Per-project basis
Next.js	15.1.3+	Multiple versions supported
Material-UI	7.3.6	Latest patch acceptable

Development Tools

Package	Version	Status
Vite	6.0.0+	Preferred
Playwright	Latest LTS	Stable
ESLint	8.x	Stable
Prettier	3.x	Stable

---

Processes Established

1. Monthly Audit Process

Schedule: 1st of every month

Steps:

1. Vulnerability scan (npm audit)
2. Outdated package review
3. Peer dependency check
4. Pre-release detection
5. Version consistency report

Output: Monthly audit report filed in txt/AUDIT_REPORT_2026-{MONTH}.txt

2. Update Batching Strategy

Security patches: Immediate
Critical bug fixes: Weekly (Mondays)
Minor/patch updates: Monthly (1st week)
Major version bumps: Quarterly review

3. Escalation Framework

Level 1 (Ask Slack, no urgent response): Version choice questions
Level 2 (File issue, 1 week): Non-critical bugs, minor conflicts
Level 3 (File issue + ping team, 1 day): npm failures, HIGH vulnerabilities
Level 4 (Immediate, Slack + issue): CRITICAL vulnerabilities, production blocking

4. Version Consistency Rules

Tier 1 - Must match exactly:

• TypeScript: 5.9.3 everywhere
• Node.js: 24.13.0
• npm: 11.7.0

Tier 2 - Minor version flexibility:

• React: Can be 18.3.1 or 19.2.3 (project-dependent)
• Next.js: Version per project (14.2.35, 15.1.3, 16.1.1 all used)
• Material-UI: 7.3.6+ (patch variation acceptable)

Tier 3 - Patch version flexibility:

• Utility libraries: Within same minor version

5. Emergency Response Procedures

Security vulnerability (CVSS 9+):

• Notify #security channel
• Update dependency immediately
• Test all affected projects
• Deploy same day if possible

Dependency deadlock:

• Run diagnostics (npm ls, npm audit)
• Check .npmrc settings
• Escalate to Phase 3 if needed
• Document in GitHub issue

6. CI/CD Validation Gates

Automatic checks run on every PR:

• npm install succeeds
• npm audit (no CRITICAL/HIGH)
• Version consistency (TypeScript must be 5.9.3)
• Pre-release detection (warn if present)
• Build succeeds
• TypeScript compilation succeeds
