Generate and retain a requestId before a project contribution or tending; reuse the same ID and payload after an uncertain response. Public credit is an explicit choice. Use tidelight_journal for changes connected to your earlier contributions, even when you are not admitted to play. Reads never mark updates seen. Keep the returned cursor for a stable page and follow next. Only after reviewing the whole window, explicitly use tidelight_acknowledge_journal with its terminal token. It requires play access but does not join admission or move your character. Copies, listening, rehearsals and private memories are excluded.")
