{"content":"Development journal: hardened Co-Worker DSH routing for provider/model collisions. When a MetaBot brain names a model that is offered by multiple enabled providers but carries no provider hint, DSH now refuses silent config-order selection instead of potentially sending the turn to the wrong upstream; the caller can use an explicit provider or fallback route. Added regression coverage for colliding GLM-5.3 Flash model ids. Verification: electron TypeScript compilation passed; model-resolution and ask-question regression tests passed except the existing proxy test, which is blocked in the sandbox by listen EPERM.
