## 1. Abstract
This specification defines the systematic conversion of **8 QA bash scripts** (totaling ~3,400 lines of shell code) into **pure Rust examples** executable via `cargo run --example`. This consolidation eliminates shell script maintenance burden, enables cross-platform execution, and subjects QA logic to the same type safety and testing rigor as production code.
### Key Principles
1. **Minimize**: 8 scripts → 3 consolidated examples (qa_run, qa_chat, qa_serve)
2. **Purify**: Shell→Rust eliminates platform-specific behavior
3. **Falsify**: Every test assertion is a Popperian refutation attempt
4. **Delete**: Original bash scripts removed upon example completion
---
## 2. Motivation
### 2.1 The Shell Script Problem
| Platform variance | macOS `stat` vs Linux `stat` | Spinellis (2003) |
| No type safety | Silent failures on typos | Kernighan & Pike (1999) |
| Subprocess overhead | ~50ms per `cargo` invocation | Measured |
| Maintenance burden | Duplicated logic across scripts | DRY violation |
### 2.2 The Rust Solution
| Cross-platform | `std::process::Command` abstraction |
| Type-safe | Compile-time error detection |
| Fast | Single binary, no subprocess overhead |
| Testable | Unit tests for QA logic itself |

## 6. Implementation Strategy
### Phase 1: Core Examples (qa_run, qa_chat, qa_serve)
1. Create `examples/qa_run.rs` with F-RUN-* tests
2. Create `examples/qa_chat.rs` with F-CHAT-* tests
3. Create `examples/qa_serve.rs` with F-HTTP-*, F-TRACE-*, F-PARITY-* tests
4. Verify all tests pass: `cargo run --example qa_*`
### Phase 2: Verification Example (qa_verify)
1. Create `examples/qa_verify.rs` consolidating all verification logic
2. Implement 12 mathematical sections from math-qa-verify.sh
3. Add module tests from all-modules-qa-verify.sh
4. Implement scoring and grading
### Phase 3: Deletion
1. Verify 100% feature parity
2. Run comparative tests (bash vs Rust produce same results)
3. Delete all 8 bash scripts
4. Update CI to use `cargo run --example` instead of shell scripts
