+**2026-08-04 Kimi K3 disposition (FN-8788):** Retain `register-model-routes-kimi-k3-supplemental.test.ts`, its `packages/dashboard/vitest.config.ts` exclusion, and its `scripts/lib/test-quarantine.json` entry through 2026-08-15. Before that deadline, removal requires a rescue with regression-value evidence and a root-cause fix; otherwise apply the normal deletion-ratchet decision when the deadline is reached.
