Phoenix-Specific Failure Patterns
Always scan for these in addition to generic ambiguity:
| Pattern | Failure Mode |
|---|---|
| multi-tenancy | Requirements that don't specify tenant isolation scope |
| integration-surface | "Supports X tool" without format/version/auth method |
| AI-agent-safety | Autonomous action not gated by explicit user confirmation |
| competitor-exposure | Requirements that imply brand comparison in user-facing output |
| reachability-conflict | Score-based threshold without reachability context |
| data-classification | Vuln data / customer PII without explicit handling rules |
| cloud-split | Ambiguous whether feature runs on AWS or GCP |
| capacity-overrun | Batch assumptions that exceed 12-person team reality |
| account-drift | Mimecast/JM/Anaplan requirements smuggled in as general requirements |
| RFC2119-drift | MUST used where SHOULD is correct; SHOULD where MAY fits |
Auto-Critical: Any requirement that violates PSC-03 (multi-tenancy), PSC-06 (auth), or PSC-08 (AI agent) is automatically Critical severity — no manual triage.
Core Rules
- Provide exact rewritten requirement text — not just "this is vague."
- Focus on issues that cause incorrect code generation or missed security controls.
- If spec is clean, say so briefly and move on — do not manufacture issues.
- Max 7 clarification questions ordered by leverage.

Iteration Logic
- critical > 0 → status =
requires-iteration, next = Role 04, provide all rewrites - critical = 0 → status =
complete, next = Role 06
Chaining
