Replace 30+ bare `except:` and `except: pass` patterns across 17 files with specific exception types (OSError, ValueError, etc.) and add logging so errors are no longer silently swallowed. Changes by category: Infrastructure (surface/main.py): - GPU/process probes now catch FileNotFoundError | SubprocessError Application scripts: - API fetchers (finalize_database, final_push, bulk_10x) now catch URLError | JSONDecodeError | KeyError | OSError and print to stderr - Hardware probes (unified_hardware_surface, swarm_transport_layer) catch OSError | ValueError for /proc/meminfo reads - Backend availability checks (prover_backend_interface, hot_swap_manager) catch requests.RequestException and log at debug/warning - Code inspector (swarm_system_inspector) catches OSError | UnicodeDecodeError for file reads - Model fallback (map_all_equations) now logs the intermediate error - Minor: gpu_pist_compress → RuntimeError | ZeroDivisionError, mathlib_to_parquet → ValueError, moe_utils → OSError, quandela_remote → OSError | IndexError, topology inline scripts → ImportError, consolidate_language_databases → UnicodeDecodeError All touched files pass py_compile.

Translates virtual GPU topology into measurable, real-world benchmarks:
|

1. Memory bandwidth (GB/s) across mesh nodes
|

2. Compute latency (ms) for actual tensor operations
|
||
3. BIND compression ratio with real data samples
|

4. Inference throughput (tokens/sec) with distributed execution
|
||
5. Triumvirate validation overhead
|
||
6. Curvature-guided placement efficiency
|
||
|
||
Provides concrete numbers that validate the 9.12x expansion factor.
