+Issue #89 adds `large-house-isometric-v1` through the same runner. Because the
+product flag expires at 1.65.0, the runner injects an explicit test-only Labs
+snapshot, selects iso per fixture space, measures the View toggle and records
+the capped `isoGeometry` cache. A comparison SHA predating #89 remains flat
+while reporting the same profile. The dedicated
 `budgets-large-house-isometric.json` applies the reviewed 20% relative allowance
 plus absolute noise/ceiling checks. Only the exact-SHA Linux workflow is gate
 evidence; a local report is diagnostic.
