10// Named z_* so it sorts after govdao_test.gno, whose TestUpgradeDaoImplementation
11// swaps the DAO implementation and asserts a hard-coded proposal id. This test
12// creates no proposal, so it is safe to run against the shared state.
13
14// A proposal id this implementation has no status for — an unknown id, or a
15// proposal that outlived the GovDAO instance that created it (statuses live on
16// the instance). The nil deref this used to hit surfaced as "runtime error:
17// nil pointer dereference", which reads like a VM fault rather than a bad
18// request.
19//
20// Note what this does NOT assert: that the proposal becomes rejectable.
21// dao.executeProposal panics on ANY error from PreExecuteProposal, ahead of
22// its execErrorRejects branch, so the guard buys a named error and nothing
23// more.
