 The supported JavaScript subset should grow when common model-generated code improves tool orchestration. These are
 current omissions to implement, not intentional product boundaries.
 
-- [ ] Complete promise-pipeline parity: assimilate supported thenables, propagate cancellation through chained promises,

+- [ ] Decide whether thenable assimilation belongs in the bounded runtime. Promise resolution currently unwraps only
+      `SandboxPromise`; arbitrary `{ then(resolve, reject) }` values remain data. Full assimilation requires internal

+- [ ] Propagate cancellation through chained promises, and consider `Promise.any`.
 - [ ] Support async iteration and `for await...of`. Define behavior first for the runtime's supported promise and
       collection values, then extend it to bounded host streams when a stream boundary exists.
 - [ ] Support callback-bearing standard-library variants that models commonly generate: the mapper argument to
