The seven core probe records move from Abdess/retrobios-measurements at
75e878143687 into this repository, copied byte for byte: one .jsonl per
emulator and a gzip data file per record. merge=union lets two branches
that each add a line merge.
A record is now one line of records/<emulator>.jsonl in the measurements repository, under 20 KB, and a gzip sidecar holding every repetition, the core logs and the raw timings, its sha256 in the line. record_version 2, core-probe-data.schema.json for the sidecar. core_probe --record appends to a measurements clone and refuses a directory inside this repository's tracked tree.
The seven records of issue 85 moved to Abdess/retrobios-measurements: each line plus its sidecar rebuilds the first file, and keeps its first id.
Seven core_probe check records for issue 85: Beetle Saturn and Yabause on a Video CD and on Lunar - Silver Star Story MPEG, each run with the eight mpeg_card.bin images, no file, zeros and a 1-byte file.
