Three things to make pickup smoother: 1. analysis/README.md (NEW): catalogues the ~25 scratch scripts. Categorizes them as "still useful" / "superseded — keep for archaeology" / "pure exploration". Tells a fresh engineer which files to read first and which to ignore. 2. scratch/next_experiment_skeleton.py (NEW): stub + spec for the segment-channel scoring analyzer. Includes the fixture loader, block walker, and decode-segment-as-channel helper — just enough scaffolding that the next pass starts from "fill in score_segment_against_all_channels()" rather than from scratch. Already runs and confirms 13 segments per 3-sec event with sample starts going to 6590 (way past the 3328 actual samples) — strong evidence that not all segments carry Tran. 3. Removed decode-re/ duplicate. It was a mirror of tests/fixtures/. Analysis scripts that hardcoded decode-re/ paths updated to point at tests/fixtures/. CLAUDE.md note updated: future event uploads go directly into a dated subdirectory under tests/fixtures/. All 40 tests still pass. Skeleton runs.
