When a mixer records a boom and lavs of the same speaker, what must be captured and avoided on set so post can combine them (alignment, comb filtering, matching)?

Sources describe a workflow in which production records every mic on its own iso track, sets input gain carefully, and logs the mix; the dialogue editor rebuilds the mix, uses lav isos to avoid perspective jumps between scenes, and aligns boom and lav in time to avoid comb filtering. DPA's vendor article gives rules for when AI dialogue matching works (no more reverb than the reference, no compression or distortion in the source), and DPA's comb-filtering article states the within-10-dB condition. The sources are practitioner statements and vendor demonstrations; none reports a controlled measurement on film dialogue.
