I could not find any information online about a "decstor" that is a recognized or established term in science, engineering, or general knowledge.

It is possible that "decstor" is:

• A misspelling: Perhaps you meant a different word.
• A neologism: A newly coined word not yet in widespread use.
• A term specific to a niche field: Used within a very specific area of study or industry.
• A proprietary term: A term used internally within a company or organization.

To help me understand what you're looking for, please provide more context.
