The specs would not likely have happened at all, since this is a solo project; although this experience has led me to want to write these things out more thoroughly, even for myself. It's impressive how little work I need to put in going this route to have fairly thorough actionable specs for pretty much every major decision I've made through the process.
The commits - some would be detailed, plenty would have been "typo" or "same as last commit, but works this time"
The tests - Probably would have been decent for the API, but not as thorough. Likely non-existent for the UI.
As for time - I agree with the other response - I wouldn't have taken the time.
