TL;DR: WJTTC v1.2.0 adds Tier 9: TAF Receipt Validation. Three checks validate .taf files (Detection, Format, Integrity). Receipts aren't scored - they're proof. 52 tests across 9 tiers.

What's New

Tier 9: TAF Receipt Validation - Receipt validator (not tester)

Three validation checks:

  • T9.1: Receipt Detection - .taf file exists, readable, not empty
  • T9.2: Format Validation - Valid YAML, required fields, TAF v1.0.0 spec
  • T9.3: Data Integrity - ISO timestamps, valid results (PASSED/FAILED), consistent test counts

When a project has a .taf receipt file, WJTTC now validates it and displays the history:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
TIER 9: TAF RECEIPT ✓ VALID
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Receipt: /path/to/project/.taf
Format: TAF v1.0.0
Total Runs: 47
Pass Rate: 97.8%
Current Streak: 12 consecutive passes
Last Run: 2026-02-02T18:30:00Z (PASSED)
First Run: 2025-12-15T10:00:00Z
Days Active: 49

Validation Checks:
   ✅ T9.1: Receipt Detection
   ✅ T9.2: Format Validation
   ✅ T9.3: Data Integrity

The Philosophy

Receipts aren't scored - they're proof.

Tier 9 is informational only. It doesn't affect the 0-100% score. A receipt is either valid or invalid (binary check). The receipt itself contains the performance data. WJTTC validates authenticity, not results.

Progressive Adoption

7, 8, or 9 tiers - all work. Any level is fine.

  • Tiers 1-7: Core MCP testing (foundation)
  • Tier 8: FAF (Claim - what you say you are)
  • Tier 9: TAF Receipt (Proof - builds trust over time)

You don't need all 9 to be legitimate. Choose your level.

The CAR Framework

WJTTC is now aware of all three components:

  • Claim (.faf file) - Developer declares what project does
  • Audit (WJTTC tests) - Proves it works
  • Receipt (.taf file) - Permanent record

"No CAR = No transport."

Try It

npm install -g wjttc@1.2.0
npx wjttc certify --mcp "npx your-server"

If your project has a .taf file, Tier 9 will validate it automatically.

💡 Pre-Certification Tip: Run Boris-Flow before certification to validate your project.faf structure. Boris-Flow's 12 tests ensure your .faf file is ready for Tier 8 validation.
