The site compiles the index and the SQLite files from measurements/
instead of a pinned clone. The pin, the sync script, the CI clone steps,
the freshness area and its refresh handler are gone. core_probe --record
writes into measurements/ of the checkout by default, and a test fails
when a line or data file HEAD holds changed or vanished.
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.
