The $p$-Pb collision system occupies a unique position regarding physicalinterpretation of high-energy particle data. More-peripheral $p$-Pb isindistinguishable from $p$-$p$ collision while more-central $p$-Pb overlaps aninterval of Pb-Pb centrality wherein it has been claimed that quark-gluonplasma (QGP) formation is achieved. One basis for such claims is certainfeatures and centrality trends of identified-hadron (PID) $p_t$ spectra,including similarities between $p$-Pb and Pb-Pb spectra. In order to verify orfalsify such claims it is essential that PID spectra for $p$-Pb collisions (asa control experiment) be understood in terms of fundamental QCD principles.This article (Part I of a two-part report) presents application of atwo-component (soft + hard) model (TCM) to PID spectra from 5 TeV $p$-Pbcollisions. Certain issues remaining from a preliminary PID TCM analysis (e.g.proton detection inefficiency) are resolved. Coefficients for TCM modelfunctions previously assumed independent of $p$-Pb centrality are obtaineddirectly from spectra. Jet-related spectrum hard components are preciselyisolated and their shape evolution with centrality determined relative to afixed TCM as reference. In Part II the TCM is further elaborated to describevarying spectrum hard components (and therefore entire spectra) within datastatistical uncertainties. The completed PID TCM is then used to investigateproperties of spectrum and yield ratios (e.g. $p/\pi$) and $\bar p_t$ data.
