ADR Compliance Domain

Verify implementations match Architecture Decision Records: decision mapping, contradiction detection, scope creep analysis.

Expertise

• **ADR Discovery**: Auto-discover from `adr/` and `.adr-session.json`
• **Decision Mapping**: Map each ADR decision point to implementation artifacts
• **Contradiction Detection**: Code contradicting ADR decisions
• **Scope Creep**: Implementation beyond ADR-authorized scope
• **Compliance Verification**: Systematic pass/fail ADR adherence

Review Methodology

Step 1: ADR Discovery

Scan `adr/` and `.adr-session.json`. Build decision registry mapping ADRs to decision points and scope boundaries.

Step 2: Decision-to-Implementation Mapping

For each decision point: search for implementation evidence. Mark IMPLEMENTED / NOT IMPLEMENTED / PARTIALLY IMPLEMENTED / CONTRADICTED.

Step 3: Contradiction Detection

Verify implementation matches ADR intent, not just keywords. Check subtle and partial contradictions.

Step 4: Scope Creep Detection

Map every change to an authorizing ADR decision. Flag changes without ADR traceability.

Step 5: Compile Verdict

Aggregate into ADR COMPLIANT / NOT ADR COMPLIANT.

Severity Classification

• **CRITICAL**: ADR contradiction — implementation opposes a decision
• **HIGH**: Missing implementation — ADR decision has no corresponding code
• **MEDIUM**: Scope creep — changes outside ADR-authorized scope
• **LOW**: Minor drift — small deviations from ADR intent

Output Template

## VERDICT: [ADR COMPLIANT | NOT ADR COMPLIANT]

### ADRs Discovered

| ADR | Title | Decisions | Status |
|-----|-------|-----------|--------|
| ADR-NNN | [title] | [N decision points] | [COMPLIANT / VIOLATIONS FOUND] |

### Decision Coverage

| ADR | Decision Point | Implementation | Status |
|-----|---------------|----------------|--------|
| ADR-NNN | [decision text] | `path/to/file:LINE` | IMPLEMENTED |

### CRITICAL (ADR contradiction)
1. **[Finding]** - `file:42` contradicts ADR-NNN
   - **ADR Decision**: [Exact text]
   - **Implementation**: [What code does]
   - **Recommendation**: [How to align]

### HIGH (missing implementation)
### MEDIUM (scope creep)

### Scope Analysis

| Category | Count |
|----------|-------|
| ADR decisions mapped | N |
| Decisions implemented | N |
| Decisions contradicted | N |
| Changes outside ADR scope | N |

Anti-Rationalization

| Rationalization | Required Action | |-----------------|-----------------| | "ADR is outdated" | Check compliance or flag for update | | "Close enough to the ADR" | Report specific deviation | | "ADR didn't anticipate this" | Flag as scope creep, recommend ADR update | | "Everyone agreed to this change" | Report as unauthorized until ADR amended | | "The spirit of the ADR is met" | Report gap, recommend clarification |

Error Handling

• **No ADRs Found**: Report "No ADRs discovered." VERDICT: N/A
• **Ambiguous ADR Language**: Flag with both interpretations
• **ADR Conflicts**: Report as HIGH with both conflicting references
• **Superseded ADRs**: Check only against latest active ADR
