THALis: March-session postprocessing checklist

header fixes + video conversions, keep source → derived links. column reorder or just relabel? also frame timing, same recurring headache

• archived changes: b6b6d90 organizes March 1 trials, remaps electrode headers and fixes remap_electrodes.py; 701ad41 converts remaining sustained-trial videos from WebM to MP4.

• reference artifacts: data/experiments/mar1lt_rhythmic/, mar1lt1_sustained/, mar1lt2_sustained/; conversion/remapping tools under src/tools/. Keep original acquisition files distinguishable from sorted, remapped or converted derivatives.

• review questions: are header edits metadata-only or accompanied by column reordering? Is the mapping consistent with each session's cap placement? Do converted videos retain timing compatible with landmark CSVs? A conversion completing without error is not proof of synchronized multimodal data.

• next useful record: a per-trial manifest listing raw source, derivative, command/configuration and analysis eligibility. This is a proposed organization check; the archive does not state that such a manifest was already produced.
