📝 Simplifying: {filename}

Changes:
- [Line X] Flattened nested ternary to switch statement
- [Line Y] Extracted repeated logic to helper function
- [Line Z] Renamed `x` to `userCount` for clarity

Diff:
```diff
- const result = a ? (b ? c : d) : e;
+ let result;
+ if (a && b) {
+   result = c;
+ } else if (a) {
+   result = d;
+ } else {
+   result = e;
+ }

### Step 7: Apply Changes

Branch on the decision matrix from Step 2:

**Autonomous + `auto_apply: false`**: skip entirely, emit the warning, return.

**Autonomous + `auto_apply: true`**: apply each change directly with `Edit()`. Do not prompt.

**Interactive + `auto_apply: true`**: apply directly, show summary at end.

**Interactive + `auto_apply: false`**: show diff per file, prompt `Apply this change? [y/N]`, apply only on yes.
