CF flag condition trace
Decode declared values, masks and repeated-mask enumerations for raw samples.

Example resultHow it works
Compare whole integers for flag_values alone, test bitwise AND nonzero for flag_masks alone, or compare masked values for the combined form. Retain repeated masks and declaration order. Use fixed-width two’s-complement patterns and preserve explicit null samples as unknown.
With masks 1,2,12,12,12 and values 1,2,4,8,12, sample 5 matches low_battery and offline_mode. The repeated mask 12 selects one enumerated bit field; it does not activate every mode.
Limits
One extracted CF1.12 table. Signed byte/short/int domains, canonical decimal integer strings and ASCII meaning tokens; no CDL suffixes or numeric JSON coercion. Provide 1–64 flags, up to 10000 samples, 250000 sample/flag cells, 2 million input characters/2 MiB UTF-8 and an 8 MiB complete report. Values must be distinct; masks must be nonzero. Mask/value reachability is a recommendation finding. Null is already-declared missing data. No default fill, valid range, packing, unsigned reinterpretation, scientific data-quality or whole-file compliance inference.
