Slice 4: Deploy vv1.89.1 to modelharbor (amd64 CI image)

[utarn]

Parent

• PRD: Upgrade fork to v1.89.1 (preserve license unlock; verify migration + passthrough cost) #1

What to build

Deploy the verified vv1.89.1 to production on modelharbor. Push vv1.89.1 so the CI image-build workflow builds the real amd64 image (NOT the throwaway local arm64 image) and pushes it to the registry. Before touching the running proxy, capture a current production database backup and check prisma migrate status for drift. Then docker compose pull litellm && docker compose up -d litellm, verify the proxy is healthy, and confirm one live glm request records response_cost > 0. Retain the previous vv1.82.3-stable.patch.4 image and the database backup as the rollback path (Prisma migrations are forward-only, so rollback is image-swap plus backup-restore).

Acceptance criteria

• vv1.89.1 is pushed and CI builds + pushes the amd64 image to the registry
• A production database backup is captured before deploy
• prisma migrate status is checked for drift before deploy
• modelharbor pulls the amd64 image and docker compose up -d litellm succeeds
• The proxy is healthy after deploy
• One live glm request records SpendLogs.response_cost > 0
• The previous vv1.82.3-stable.patch.4 image and DB backup are retained for rollback
• Only the modelharbor litellm stack is touched (other litellm stacks on the host are untouched)
