description	Guide and workflow for Dice Real-Mode Tests (MCP). Use when you need Dice Real-Mode Tests (MCP).

Dice Real-Mode Tests (MCP)

Use this when validating dice integrity end-to-end with real services.

Script Location

• testing_mcp/test_dice_rolls_comprehensive.py

Required Standards

• Evidence: Follow .claude/skills/evidence-standards.md (Three-Evidence Rule)
• Authenticity: Follow .claude/skills/dice-authenticity-standards.md (Chi-squared + RNG verification)

Preview Server (real mode)

python testing_mcp/test_dice_rolls_comprehensive.py \
  --server-url https://<preview-app>.run.app/mcp \
  --evidence \
  --evidence-dir /tmp/<run-id> \
  --models gemini-3-flash-preview,qwen-3-235b-a22b-instruct-2507

Notes:

• Distribution tests will skip if roll_dice tool is unavailable on preview.
• Qwen/native_two_phase uses server tool_results as authoritative; mismatches are overridden.
• Use a unique /tmp/<run-id>/ (timestamp or UUID) per run to avoid collisions.

Local MCP (real services)

python testing_mcp/test_dice_rolls_comprehensive.py \
  --start-local --real-services --evidence --enable-dice-tool \
  --models gemini-3-flash-preview,qwen-3-235b-a22b-instruct-2507 \
  --evidence-dir /tmp/<run-id>

Outputs:

• run.json (scenario results, tool_results, dice_audit_events, warnings)
• local_mcp_*.log (server logs)
• raw_*.txt (raw model responses when enabled)

What This Covers

• Gemini code_execution path (dice_audit_events source=code_execution).
• native_two_phase path (Qwen/Cerebras tool_results).
• Distribution tests (1d6 / 1d20) when roll_dice tool is available.
• Edge cases (invalid notation, 1d0+5).

Common Expectations

• DICE_ROLLS_MISMATCH / DICE_AUDIT_MISMATCH warnings can appear; server overrides with tool_results.
• Final run.json should show aligned totals across dice_rolls, dice_audit_events, and tool_results.

Chi-Squared Validation

After running distribution tests, validate authenticity:

Chi-Squared	Sample Size	Verdict
< 30	100+	PASS
30-50	100+	WARNING - Investigate
> 50	100+	FAIL - Likely fabrication

Reference: PR #2551 detected fabrication with chi-squared = 411.81

Troubleshooting

• If native_two_phase fails: ensure tool_results are present in responses.
• If mismatch errors appear in run.json: check the log and confirm override occurred.
• If distribution tests skip on preview: expected unless roll_dice tool is exposed.
• If chi-squared > 50: Check rng_verified field in evidence - may indicate fabrication.
