ApplicationsStore.cancel and AdminCasesStore.delete rolled an optimistic write back on failure but showed no message — a bare catch with no Result and no error channel (CQ-002). Both now call runSubmit and set a lastError signal on failure, mirroring createSubmitChangeRequest in the same folder. Each page renders the error with the existing app-alert atom, the same pattern brief.page.ts already uses for lastError. Added a spec file for ApplicationsStore (none existed) and extended AdminCasesStore's spec, each asserting the rollback AND the surfaced error. Verified both new assertions fail without the fix (an Edit undo/redo of the store method, not git checkout). Regenerated libs/shared/docs/behaviour-spec.mdx (gen:behaviour-spec) to pick up the new/renamed test names. Marked RB-20 done in 99-backlog.md and recorded the change in implementation/rb-20.md.
