✅ executor.go:77-79 - Content-Type Fix (No Issues)

This is a correct fix. Setting Content-Type: application/json only when there's a request body is proper HTTP behavior. Previously, this header was incorrectly sent on GET/DELETE requests without a body.

⚠️ update_tests.go:268 - Defensive Nil Check Removal (WARNING)

The PR removes the if m.testVars != nil guard before calling extractVars(). While the PR description states this was an "always-true" guard, there are remaining nil checks in the same function:

• Line 205: if m.testVars != nil
• Line 235: if bs, ok := b.(string); ok && m.testVars != nil

These remaining checks suggest testVars can potentially be nil in certain scenarios. If extractVars() is called when testVars is nil, it will panic at lines 143-145 when trying to write to the nil map:

m.testVars[as] = v  // panic: assignment to entry in nil map

Recommendation: Either:

1. Keep the nil check for defensive safety, or
2. Document why the remaining nil checks (lines 205, 235) are still necessary while this one isn't

The executor.go change is correct and safe. The update_tests.go change appears safe under normal flow (since handleStartTestGroup initializes testVars before tests run), but removing defensive code always carries some risk.
