Mission briefing
Mission 4-C: Your one-line color token change came back with a wall of red: "47 tests failing." Forty-seven. From one line. Before you panic, the Tech Lead drops a calming message: this is exactly what the system is supposed to do.
Don't panic. Those 47 tests are automated checks that confirm parts of the app still behave correctly. Your color change touched a token that 47 components rely on, so 47 checks re-ran. Most are probably just expecting the old value. The system is working, not screaming.
The fact that 47 tests even cover that token is good coverage — a measure of how much of the code has tests watching it. High coverage means changes can't quietly break things. You're getting loud feedback precisely because this area is well protected.
Also — linting flagged a formatting nit in your file. Linting is an automatic style-and-consistency checker. Harmless, just tidy it. And once green, your change goes through code review: a teammate reads it, comments, approves. That's the human checkpoint on top of the automated ones.
Your token change fails 47 tests that expected the old color value. What's the right next step?
