Frees the WASM memory of this ExecutionContext, since these cannot be garbage-collected automatically.
Request cancellation. Can be called from any context. Idempotent.
Has cancellation been requested?
Normalized progress in [0, 1]. Monotonic within an evaluation. Returns 1 when no work has been scheduled (interpreted as trivially complete -- e.g. a single-leaf manifold has nothing to evaluate).
Like Manifold.smooth, observed/cancellable via this context.
OptionalsharpenedEdges: readonly Smoothness[]
Observe and control a long-running Manifold evaluation. Attach to a Manifold via Manifold.withContext(); the next eager op invoked on the result (status(), one of the refine* family, hull(), or minkowskiSum() / minkowskiDifference()) snapshots the ctx and reports progress / observes cancellation through it. Deferred ops (Boolean, transforms, batch ops) ignore any attached ctx. Safe to read/write from any thread/worker.
Cancellation is permanent for a Manifold: once cancelled and detected, the Manifold's status becomes 'Cancelled' and stays 'Cancelled'.
