- In progress.
- Initial validation on `2026-04-12`: after the DLOB hot/all-path rollout, sampled Agave slot lag on `sol` at `0` versus `https://api.mainnet-beta.solana.com`, with local health still reporting `ok`.
- Done on `2026-04-12`: adjusted the canary rollout model to match the namespace guardrails by switching deployments to `RollingUpdate { maxSurge: 0, maxUnavailable: 1 }`, adding explicit low CPU limits to `api-token-seed`, and making the workflow restart the surface sequentially instead of all at once.
- Done on `2026-04-12`: after the sequential smoke rollout on `sol`, all canary deployments returned to `Available=1/1`, `trade-api /v1/ticks` and `/v1/chart` returned data, and the validator still reported `lag=0`, `health=ok`.
### 24. Keep `mevnode_bot` as a rollback target until the new stack is stable
