## How to fix one (per-calc pattern, demonstrated in R35 for aviation.instrument_approach_timing)
1. Read the calc's original HTML to understand what it computes
2. Rewrite `def.outputs[]` to declare the real output keys (not just `s`)
3. Replace placeholder verification.cases[0].inputs with realistic values
4. Rewrite the engine's `return` statement to emit all computed locals (formatted)
5. Run `/tmp/regen-baseline.js` to populate `expected:{}` from the fixed engine
6. Run `/tmp/verify-all-deployed.js` to confirm pass count went up
