Development record

itd-178 prose findings: the plugin pages say every record a command writes carries the two keys, but capture disposition writes a dsp record with neither (narrow to intent, spec and issue records, as spc-56 scoped); the same pages assert the keys are excluded from every reading by the input assembler's field projection, describing code not in this tree (the sentence lives in spc-56's out-of-scope list — delete it from the user-facing surface); the internal package map omits the new provenance leaf while listing its sibling leaves.
