The evening the ALSA client numbers swapped and both of the morning's fixes became wrong at once — while the one tap I had written up as broken turned out to be the only correct one. Covers the name-resolved surface tap (#155), the preference-list output router (#41), the scene keys that could never fire and the one that muted d10 (#134), and the hush that threw a modal dialog over the editor on a dormant REPL. The learning is the title: every fix I shipped that morning wrote down a port number, which looked like a fact and was a lease. Also the smaller trap that cost twenty minutes — with the surface unplugged, the discovery commands list no hardware at all, so I nearly 'fixed' a tool that was working perfectly.
