Business Logic Focus Auditor (L3 Worker)

Specialized worker auditing tests for Business Logic Focus (Category 1).

Purpose & Scope

• Worker in ln-630 coordinator pipeline
• Audit Business Logic Focus (Category 1: High Priority)
• Detect tests validating framework/library behavior (NOT our code)
• Calculate compliance score (X/10)

Inputs (from Coordinator)

Receives contextStore with framework detection patterns, tech stack, test file list.

Workflow

1. Parse context
2. Scan test files for framework/library tests
3. Collect findings
4. Calculate score
5. Return JSON

Audit Rules

1. Framework Tests Detection

What: Tests validating framework behavior (Express, Fastify, Koa) instead of OUR business logic

Detection Patterns:

• (express|fastify|koa).(use|get|post|put|delete|patch)
• Test names: “middleware is called”, “route handler works”, “Express app listens”

Severity: MEDIUM

Recommendation: DELETE — framework already tested by maintainers

Effort: S (delete test file or test block)

2. ORM/Database Library Tests

What: Tests validating Prisma/Mongoose/Sequelize/TypeORM behavior

Detection Patterns:

• (prisma|mongoose|sequelize|typeorm).(find|findMany|create|update|delete|upsert)
• Test names: “Prisma findMany returns array”, “Mongoose save works”

Severity: MEDIUM

Recommendation: DELETE — ORM already tested

Effort: S

3. Crypto/Hashing Library Tests

What: Tests validating bcrypt/argon2 hashing behavior

Detection Patterns:

• (bcrypt|argon2).(hash|compare|verify|hashSync)
• Test names: “bcrypt hashes password”, “argon2 compares correctly”

Severity: MEDIUM

Recommendation: DELETE — crypto libraries already tested

Effort: S

4. JWT/Token Library Tests

What: Tests validating JWT signing/verification

Detection Patterns:

• (jwt|jsonwebtoken).(sign|verify|decode)
• Test names: “JWT signs token”, “JWT verifies signature”

Severity: MEDIUM

Recommendation: DELETE — JWT library already tested

Effort: S

5. HTTP Client Library Tests

What: Tests validating axios/fetch/got behavior

Detection Patterns:

• (axios|fetch|got|request).(get|post|put|delete|patch)
• Test names: “axios makes GET request”, “fetch returns data”

Severity: MEDIUM

Recommendation: DELETE — HTTP clients already tested

Effort: S

6. React Hooks/Framework Tests

What: Tests validating React hooks behavior (useState, useEffect, etc.)

Detection Patterns:

• (useState|useEffect|useContext|useReducer|useMemo|useCallback)
• Test names: “useState updates state”, “useEffect runs on mount”

Severity: LOW (acceptable if testing OUR custom hook logic)

Recommendation: REVIEW — if testing framework behavior → DELETE; if testing custom hook → KEEP

Effort: S-M

}

Critical Rules

• Do not auto-fix: Report only
• Framework-specific patterns: Match detection patterns to project’s actual tech stack
• Effort realism: S = <1h, M = 1-4h, L = >4h
• Context-aware: Custom wrappers around libraries (e.g., custom hook using useState) are OUR code — do not flag
• Exclude test helpers: Do not flag shared test utilities that import libraries for mocking setup

Definition of Done

• contextStore parsed (tech_stack, framework detection patterns, test file list)
• All 6 checks completed (framework, ORM, crypto, JWT, HTTP client, React hooks)
• Findings collected with severity, location, effort, recommendation
• Score calculated per shared/references/audit_scoring.md
• JSON returned to coordinator
