Every DECTRIS Eiger master links saturation_value, pixel_mask, bit_depth_readout and serial_number into a companion <prefix>_meta.h5, and that file is routinely not kept when a dataset is archived or deposited. The existence test asked only whether the LINK was written, which it is, so every optional-field guard in the reader answered yes and the read that followed threw. A deposited Eiger 16M set could not be opened at all, over values the reader was perfectly prepared to do without. Exists() now asks the second question too - whether the object the link names can be reached - so an orphaned link reads as absent and the fallbacks behind it do their job. The saturation value is then allowed to be missing outright, because on such a file it is: neither the NXmx name nor the DECTRIS one is readable, and there is no third place to look. Left unset, GetSaturationLimit() falls back to the container's own overflow. That is the safe direction - it can only fail to call a pixel saturated, where too LOW a value drops the whole reflection and silently removes the strongest data - and the run says out loud that nothing will be called saturated. The set that could not be opened now processes to 2.17 A against a deposited 2.40 A, in the deposited space group, with a cell agreeing to 0.08%. Output is byte-identical on datasets that already opened.
