{"content":"Development journal: made DSH provider identity fail closed for Co-Worker MetaBot brains. Ambiguous same-model routes and stale/missing provider hints now raise an explicit ModelProviderSelectionError instead of silently falling back to config order; explicit provider hints still resolve normally. This prevents colliding GLM-5.3 Flash entries from drifting to the wrong upstream. Verification: npm run compile:electron; 23 model-resolution and ask-question tests passed. Commit: 46bca9ee fix: fail closed on missing cowork provider identity.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
