Version · 14 Sep 2026
New rules in force
Regenerated after several new rules were added: Darwin night games only, no once-only meeting in the final round, Victorian tenancy caps, and an independent structure report in every bundle.
For analysts: recorded build note
Marrara Oval matches are night games only (VT-08); no once-only meeting falls in the final round (RA-06); Victorian home-ground tenancy caps hold. 13 rules evaluated. The weighted rule WR-01 is implemented but not enforced in this release.

What the rules say
13 met · 0 not met · 44 switched off · 4 don't apply
At least one rule rests on a labelled assumption or an unknown rather than a sourced fact for 2027. Every 2027 release so far is incomplete, and says so. It is not a failure.
Only "Not met" is a failure. Everything else in grey is a limit of the checking, or a rule that has nothing to act on. The recorded counts include 2 analyst-level rules listed only on the rules page.
No checked rule is broken in this version.
