+# ADR-0016 — Database-backed GPU lease coordination
+
+Status: accepted (M5)
+
+GPU admission uses persisted leases and a locked accelerator row. Correctness therefore does not
+depend on one API process or an in-memory mutex. Server timestamps, expiry and reconciliation make
+crashed-request reservations recoverable.
