Human view
What a person naturally reads, sees, or hears.
Syntactic alternatives can preserve a proposition while changing information structure and style. The page analyzes predefined safe pairs rather than manufacturing deceptive prose.
Research boundary: this page uses bounded, inert data and fixed safe examples. It never executes decoded content, requests secrets, calls third-party services, or performs actions against external systems.
Inputs remain on this host. Text operations are size-limited; uploaded files are processed from PHP’s temporary upload and are not retained by the application.
The response will separate summary metrics, representation views, findings, tables, and any generated safe fixture.
What a person naturally reads, sees, or hears.
What a parser, DOM, container reader, or metadata extractor exposes.
What becomes meaningful only with a rule, key, tokenizer, model, or tool.
What normalization, rendering, OCR, canonicalization, or policy changes.
Syntactic alternatives can preserve a proposition while changing information structure and style. The page analyzes predefined safe pairs rather than manufacturing deceptive prose.
Machine-decodable is receiver-relative. Record the parser, preprocessing, codebook, tokenizer, key, model, and transformation path before generalizing from one result.
Active and passive realizations are not always pragmatically equivalent. The heuristic parser is educational and does not replace a full syntactic parser.
