[Solved] Rosetta 2 Translation Failure: ‘oahd: dyld shared cache architecture mismatch’ on Mac mini M2: How to resolve Corrupted Rosetta runtime translation cache after major macOS incremental delta update

Diagnostic Hardware Specs: Mac mini M2 | OS Version: macOS Sequoia 15.1 | Archive Source: Apple Support Community #256219473

I am running into a persistent issue on my Mac mini M2 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 0xd054: 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?
