Diagnostic Hardware Specs: MacBook Pro 16″ M2 Max | OS Version: macOS Sequoia 15.1 | Archive Source: Apple Support Community #256075237

I am running into a persistent issue on my MacBook Pro 16″ M2 Max running macOS Sequoia 15.1.
Whenever the machine encounters Corrupted Rosetta runtime translation cache after major macOS incremental delta update, the following diagnostic log appears in Console:

oahd: [com.apple.oahd] Failed to translate binary chunk 0x6628: Invalid Rosetta dyld shared cache

I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?
