Progress update, 10 Aug 2026

Updates are bullet-point summaries generated with AI from my commits and build notes, then checked by me. Project articles and learning notes are written by me.

The one-year circuit can’t fail a denominator test, since dividing by one changes nothing. Only the three-year circuit now counts as evidence for averaging checks.
Replaced the comparison script. It never compared race_phases, sorted lists the code deliberately orders, and keyed grandstands by the non-unique code. The new one compares every field and requires accepted differences to be declared.
Froze the old pipeline’s output in baseline/, pinned to a commit, so validation doesn’t end up comparing the database with itself after cutover. Widened validation from 195 to 525 keys and confirmed the checks can fail.
Resolved a suspected unzoned incident (zones 7/7/7 against a total of 8). The zones overlap, so nothing was wrong.
Added a source_incidents table: the circuit summary counts spreadsheet rows, not row and section pairs, and one 2023 row with no section could not be recovered from incidents.
