Two tests pinned Marcus's Debt route count to exactly two, so any general (Schema 2) plot whose matcher also covered custodian+Debt broke the lib gate and forced a Rust/test edit. That contradicted the plot contributor contract ("adding a plot needs no Rust registry edit") and the general-by-default principle. The tests now assert that Marcus's two authored routes surface (present, enabled, interpolated, priced) and that queued-category alternates stay visible-and-disabled (>= 2), rather than asserting exact totals. Defense: honors wiki/mechanics/plots.md's content-only contributor contract and the plot-author general-by-default rule. A bespoke character's authored routes are still guaranteed to surface; general plots may now add routes to a covered category without editing Rust. plots.md carries the 2026-07-12 covered-category amendment. Test-and-doc change only; no runtime behavior change.
