Command: the batch carries ExpectUnchanged, so CultCache lands it onto the file as it is. A plain commit re-encoded every record through today's types (two sensors lost a retired key-7 payload and gained a trailing nil, LRMM72 and GT 3K gained a trailing nil); this one leaves every record it did not author byte-identical. A conflicting writer now fails the apply instead of being overwritten.
Tests: the mild baffle stores exactly flash x Factor and pays exactly its predicted heat for the first 30 launches of a 300 flash or 8 of a 1000 flash, then is either hidden or bright; the rating is pinned to half a kelvin either side at three heat-sink qualities; suppression and heat are checked at six flash strengths; the observer fits the named sensor 'not if i see you first'; the command test widens every payload and checks apply leaves all other records byte-identical.
This commit's GameData/Aetheria.cc pointer is the previous apply's output; the regenerated catalog follows in its own commit. Not built or run at this commit yet.
