## Scoring Worksheet

### impl-1
**Fitness for Purpose** (Does it solve the actual problem?)

*Functional requirements:*
- [ ] Primary use case works end-to-end?
- [ ] All explicitly stated requirements implemented?
- [ ] Handles realistic scenarios, not just happy path?

*User needs (beyond literal requirements):*
- [ ] Would the user actually use this, or just demo it?
- [ ] Does it solve the real problem, not just the literal request?
- [ ] Does deployment/distribution match stated needs?

*Future considerations (if relevant):*
- [ ] If growth/scaling mentioned, does architecture support it?
- [ ] If team/collaboration mentioned, is it maintainable by others?

Checklist: _/8 YES → **Score: _/5** (7-8=5, 5-6=4, 4=3, 2-3=2, 0-1=1)
*Note: Not all items apply to every project. Score based on relevant items.*

**Justified Complexity** (Every line earning its keep?)
- Unnecessary abstractions: ___
- Dead code: ___
- Bloat estimate: ___%

*Line count comparison (if multiple impls):*
- This impl: ___ lines
- Smallest impl: ___ lines
- Extra lines justified by: ___

→ **Score: _/5** (5=minimal, 4=slight bloat <10%, 3=10-25% bloat, 2=25-50%, 1=>50%)

**Readability** (Understand core flow in 5 min?)
Violations:
- [ ] Single-letter vars (not loop index): +1 each = __
- [ ] Functions >50 lines: +1 each = __
- [ ] Nesting >3 levels: +1 each = __
- [ ] Magic numbers: +1 each = __
- [ ] Bad function names: +1 each = __
Total violations: __ → **Score: _/5** (0=5, 1-2=4, 3-4=3, 5-7=2, 8+=1)

**Robustness & Scale** (Handles unexpected + growth?)
- [ ] Input validation?
- [ ] External call error handling?
- [ ] Useful error messages?
- [ ] Null/empty handling?
- [ ] Async timeouts?
- [ ] No unbounded loops?
- [ ] O(n log n) or better?
- [ ] Bounded memory?
- [ ] Queries paginated?
- [ ] No blocking I/O in hot path?
- [ ] Backoff/retry logic?
- [ ] Handles 10x load?
Checklist: _/12 YES + feasibility flags → **Score: _/5**
(11-12 + no flags=5, 9-10 or minor flag=4, 7-8=3, 5-6 or major flag=2, <5 or critical flag=1)

**Maintainability** (Pain of next change?)
- [ ] Single responsibility per function?
- [ ] Explicit dependencies (no globals)?
- [ ] Business logic separated from infra?
- [ ] New feature = ≤3 files changed?
- [ ] Config externalized?
- [ ] Tests catch regressions?
Checklist: _/6 YES → **Score: _/5** (6=5, 5=4, 4=3, 2-3=2, 0-1=1)

### impl-2
[REPEAT SAME FORMAT]

### impl-3 (if applicable)

## Winner Selection
**Winner: impl-X** (Score: __/25)

**Selection rationale:**
[2-3 sentences explaining WHY this implementation won]

**Trade-offs acknowledged:**
[What the other implementations did better]

**Token efficiency note:**
[How the winner used hosted LLM - fewer fix cycles, better prompts, etc.]
