E.11.PFP:9 - Consequences

Readers retain each product’s compact familiar opening and find Readme and Preface in the ToC grammar already used by that product, before the one authoritative pattern index. Inside the Readme they see one explicitly non-exhaustive practical-entry set: ordinary examples show cheap direct use, while only honestly selected cross-pattern cards add a visible mantra and an optional bounded expansion. Optional public cues remain recoverable from one source when they change use, while development and rebuildability records stay out of reader front matter. Builders gain checks that fail on missing public-unit entries, duplicate or cross-form keys, card grammar, structural, projection, and development-state drift without guessing table meaning, deciding card value or coverage, or inventing a rival navigation block.

The whole account also makes shared choices and source synthesis accessible beyond individual bodies. Authors can refine one profile without copying the entire language, and readers can see which answers remain inherited. Keeping those returns current costs work; concentrating the shared explanation reduces the number of independently editable copies.
