All search space bounds now derived from HardwareBudget methods: - batch: budget.max_batch_size() - hidden_dim: budget.max_hidden_dim_base_full() - dueling/branch: proportional to max_hidden (50%/25%) - buffer: 15% VRAM / 120 bytes per entry - atoms: 5% VRAM / per-atom tensor cost - accum: proportional to VRAM / 10GB Removed small_gpu/large_gpu boolean tiers entirely. A 24GB GPU now gets bounds between 4GB and 80GB values, not arbitrarily bucketed. Phase Fast fixed bounds (lo==hi) still skipped — never modified.
