ConstReadonlyKEY_GENERATION: 700000Key-generation timeout: 700 s. Covers CGGMP24 worst-case (10–60 s+) with margin, below the engine's 600 s cap.
ReadonlySIGNING: 120000Signing timeout: 2 min. Well above typical threshold-signature duration across well-connected nodes.
BullMQ job timeout constants, in milliseconds.
These values are set slightly above the Rust engine's internal limits so that the engine always returns a proper gRPC error before BullMQ kills the worker process.
