Plan
- Add a dependency-free PHP helper and common-envelope adapter.
- Test positive facts, no-source skip, missing runtime and invalid syntax.
- Run an isolated before/after pipeline on a PHP-bearing semcod repository.
- Record exact evidence and run repository gates.
Responsibility boundary
The adapter records syntax observations only. It does not infer user intent or
claim that token parsing exposes every semantic property of a complete PHP AST.
