Harness-backed PR verification: useful, and where would you want it pointed?

[m4bard]

I have been checking open PRs by building the branch and running it against a test harness rather than by reading the diff, and I would rather ask whether that helps than keep guessing.

The harness generates a synthetic audiobook library from public-domain metadata and drives a real container through the API, so it answers things a diff cannot. Three recent examples:

• fix: normalise author group keys to prevent duplicate author cards (#672) #673, that the author grouping key collapses every non-Latin name to the same value, so three different authors render as one card
• fix(search): zero configured indexers returned five fake mock releases into the real grab pipeline #756, that the mock indexer results reach quality scoring through AutomaticSearchService, which runs on a timer rather than only on a user-initiated search
• Incorrect size for audiobook given #542, that the size shown for a book is one file's size rather than a total, which is why some books show none at all

It seems to be landing with the people whose PRs I commented on. dny238 revised #784 and #781 off the back of it, and t3chnaztea folded the #756 finding into that PR's description. What I do not know is whether it helps you, which is the part that matters, since you are the one who has to merge any of it.

So, two questions, and a one-line answer to either is plenty. Is this useful, or is it just more to read? And if it is useful, is there anything you would rather I pointed it at than whatever I happen to pick?

I have twenty comments across seventeen threads now, most of them in the last few days, and I would rather stop than add noise while you are heads-down. I have also stayed out of #717's area unless something looked like it would collide with it, on the assumption you do not want that branch disturbed. Say if that is backwards.

The harness is at https://github.com/m4bard/listenarr-testdata and everything above is reproducible from it. No reply needed if the answer is "not now".
