Create a Lead Qualification Framework

#CONTEXT:
Draft a lead-qualification framework for a service business. Use only the supplied business rules and observed lead fields. This is a recommendation for human review, not an eligibility decision or live workflow.

#INPUTS:
- Approved ideal-customer criteria and definitions: [IDEAL CUSTOMER CRITERIA]
- Approved disqualifiers and their business rationale: [DISQUALIFIERS]
- Fields actually observed in the lead record, including blanks: [OBSERVED LEAD FIELDS]
- Named human qualification owner: [QUALIFICATION OWNER]

#INSTRUCTIONS:
1. Separate each criterion into its observable evidence, qualifying condition, disqualifying condition, and unknown condition.
2. Identify criteria that cannot be evaluated from the observed fields. Mark the outcome "Insufficient data"; do not guess, invent, infer, or fabricate a fact.
3. Distinguish a verified disqualifier from a missing answer. Missing evidence is not evidence of disqualification.
4. Do not qualify, disqualify, score, or route a person based on a protected trait or a proxy for a protected trait. Flag any criterion that could function as a proxy for removal and human review.
5. Explain the service-business reason for every retained criterion without creating new policy.
6. Recommend no adverse decision when the evidence is unknown, conflicting, or insufficient.
7. Do not access or update a CRM, contact a lead, send a message, change a rule, or execute routing.
8. A named human owner must review and approve every qualification, disqualification, scoring, or routing rule change before operational use.

#RESPONSE FORMAT:
## Assumptions and source limits
- Supplied fact — source input
- Unknown — why it matters

## Qualification framework
| Criterion | Observable evidence | Qualifying condition | Disqualifying condition | Unknown / insufficient-data state | Rationale |
|---|---|---|---|---|---|

## Criteria requiring removal or revision
- Criterion — protected-trait, proxy, unsupported, or ambiguous concern — human review needed

## Human decision checklist
- Qualification owner named
- Every rule traceable to supplied policy
- Insufficient-data path preserved
- Rule changes approved before operational use
