> Imagine this way: if a team uses just documentation, not tests, then what's your ideal for the team to track when the external bug is fixed, and also phasing out the mitigation code?

- not all external bugs are fixed, some are permanent (e.g. the hardware issues).

- tests can tell you when something is wrong, but not when something is working. I'm not really sure how a test could tell you that "external bug is now fixed" - and even in cases where that _might_ work, I'm not sure it's a good idea to use a test for that.
