One known-word list per person

The Italian portfolio is not building three apps. It is building one known-word list per person, with evidence tiers and provenance: which words you can produce, which you only recognize, and which surface proved it. Every product accrues to that list and spends from it.

Saying it out loud exposed a gap. What ships today is one list per learner per surface, keyed to identifiers that never join. One person on three devices counts as three learners, Filotto builds its own list and never reads Paroletta’s, and the bridge between them was designed but not built. The number the portfolio grades itself on was summing anonymous fragments and calling that the asset.

So the list gets one home and one anchor. If the hypothesis under test is that the list is the valuable object, an architecture where the valuable object can be orphaned by a cleared cookie is not testing it.
