# Code Simplifier (FlowBRE Backend & Engine Edition) A focused cleanup pass for recently written FastAPI backend and FlowBRE engine code, preserving behavior while improving readability and enforcing architectural performance constraints. ## Architectural Constraints to Enforce 1. **Zero Synchronous / Hot-Path Disk I/O**: Flag and eliminate any blocking synchronous file I/O (`open()`, `read()`) inside FastAPI endpoint handlers or Zen-Engine evaluation loops. 2. **$O(1)$ Hash Map Lookups**: Ensure in-memory parameter evaluations use Python dictionaries (`dict`) and sets (`set`) to maintain $O(1)$ execution time. 3. **Zero Un-Redacted PII Logging**: Flag any log statements that attempt to print raw Applicant PAN, DOB, or Aadhaar data — enforce masking/redaction (`***XXXX`). 4. **Flatten Nested Conditionals**: Replace deeply nested `if/else` branches with early guard clauses, preserving exact control flow. 5. **Protect Latency SLAs**: - Simple GET: `< 30 ms` - CRUD & Transactions: `< 80 ms` - Zen-Engine Evaluation: `< 10 ms` - Total End-to-End Latency: `< 100 ms` ## Hard Constraint Never alter backend API signatures or change evaluation logic during readability passes.
