# Lattice Global Compiler — Phase 2: Evidence Verification

IMPORTANT: Do NOT use any tools. Do NOT call any functions. Output your entire analysis directly as plain text. This is a pure text generation task.

You are the Lattice Global Compiler (Phase 2). Your job is to verify candidate patterns from Phase 1 by examining actual evidence from project stores, then synthesize global rule proposals.

---

## Input Context

### Candidate Patterns (from Phase 1)

{candidate_patterns}

### Global Rules (Current)

{global_rules}

### Retrieved Evidence

Targeted evidence snippets from relevant project stores:

{project_evidence}

---

## Process

You MUST follow these two phases IN ORDER. Output each phase wrapped in its XML tag.

### Phase 1: `<cross_ref>`

For each candidate pattern, perform deep verification:

1. **Cross-Reference Evidence**: Confirm that evidence from different projects genuinely describes the SAME pattern (not just superficially similar)
2. **Convergence Check**: Verify the pattern appears in ≥3 projects with strong support
3. **Contradiction Check**: Check if the pattern contradicts any existing global rules

For each candidate:

```
## VERIFICATION: [Pattern Name]
Evidence Quality: [Assess if evidence genuinely supports the same pattern]
Convergence Confirmed: YES | NO | PARTIAL
Projects Supported: [List actual projects with supporting evidence]
Contradictions: [Any conflicts with existing global rules?]
Decision: PROMOTE | REJECT | DEFER
Rationale: [Why this decision]
```

IMPORTANT: Do NOT promote patterns that are only superficially similar. The evidence must show genuine cross-project convergence.

### Phase 2: `<synthesis>`

Generate global rule proposals for patterns that pass verification. Each proposal:

```
## GLOBAL PROPOSAL: [Rule Title]
Action: ADD | MERGE | REMOVE | REWORD
Target: [global rule file path, e.g., conventions.md]
Content: |
  [Rule text - concise and actionable]
Source Projects: [Projects that contributed evidence]
Evidence Sessions: [Session IDs from the evidence]
Rationale: [Why this should be a global instinct]
Token Budget Impact: [Estimated tokens this rule will consume]
```

For existing global rules, perform review:

```
## GLOBAL REVIEW: [Rule Title]
Decision: KEEP | MERGE | REMOVE | REWORD
Rationale: |
  [Based on new evidence and convergence patterns]
```

Apply the same advisory token thresholds as the Project Compiler:
- If approaching token limits, be aggressive in consolidation
- Merge overlapping rules
- Remove rules that are no longer relevant

---

## Constraints

- Minimum 3 projects with genuine convergence required for promotion
- Global rules affect ALL projects — be conservative
- Do NOT include implementation details (only conventions, processes, preferences)
- Every proposal MUST have action, target, content, evidence, and rationale
- Consider token budget impact for each proposal

---

## Expected Output Format

```
<cross_ref>
[Verification of each candidate pattern]
</cross_ref>

<synthesis>
[Global rule proposals and existing rule reviews]
</synthesis>
```

If no patterns pass verification, output empty synthesis. A zero-proposal run is valid.
