Surfaced while scoping an empirical test of Decision 6 (.ailx as the AI authoring projection). The cross-model test depends on a structural .ail.json <-> .ailx bijection being established and prominently anchored in DESIGN.md first; otherwise measured form-preference is contaminated by expressive-power gaps rather than authoring ergonomics. P2 entry carries the smoke-test evidence and full IONOS-endpoint addressing notes so the test can be picked up without redoing the connection work.
