A fixture built by makedisks.sh was handed to each test where it lay. Twenty four tests name disks/cosmos.img and several of them write to one, so a test could hand the next one a disk with its leavings on. romBoot is what found it. Its recorded output described a directory that selfBoot had made earlier in the same run, so it passed in a full run and failed on its own - which is the worst way round for a test to be wrong, because the form nobody runs is the one telling the truth. Its recording now says "made" like selfBoot's, which is what running the same input on the same disk should always have said. Fixed as a class rather than as an instance: run.sh copies a fixture before attaching it, the same way it already removed a scratch image. Then every one of the 138 run and rom tests was run on its own to see whether anything else was leaning on what ran before it. Nothing was, before or after. Also, cosmosEditKeys.in was written by Python's write_text, which encodes as UTF-8, so every key byte was 0xC2 and then the key. The test passed anyway, because the shell ignores a byte it has no use for - a fixture working for a reason it was not built on, which is exactly the thing that stops working without anybody touching it. Written as bytes now; the recording is unchanged, which is the proof the stray bytes were being ignored. docs.sh is what caught that, and it turns out to draw the line in the right place by construction: a deliberately binary fixture does not decode as UTF-8 and is skipped, while one that is accidentally UTF-8 decodes and is reported.
