Turns a request path plus the two routing fields (`do`/`action`) into a single Resolution for BOTH doors (D-039): the RESERVED level-1 switch first (home/access/setup/api/static/media/ws/dev — D-004), then the GUID classifier, then the registry. Identity and the module registry are injected interfaces, so the package is PURE — no HTTP stack, no DB (asserted by purity_test.go). All 22 spec rows are covered.
