A Hash or Hmac that flows into an unknown or any slot, or into untyped
JavaScript code, is now a native handle (Hash or Hmac) instead of a
compile error. The handle keeps the value's identity, so a cast back to
Hash or Hmac answers the same value. update(), digest() and Hash's
copy() dispatch through it, called directly or read as values: update
is one function for Hash and Hmac and digest is one per class, as in
Node 24.22, and update() answers the receiver. The stream and event
members throw a coded SC2020 error there, as do the methods called with
another receiver; other names read as undefined.
The to-dyn conversion boxes a Hash or Hmac through
scr_crypto_hash_to_dyn, which installs the handle ops on first use, so
programs that never box one link none of the handle code.
A native handle read through `as any` now dispatches its method calls
through the handle. Calling copy() on an Hmac throws Node's TypeError
("mac.copy is not a function") after the arguments are evaluated,
instead of the method-call fence.
Corpus 5768 and 5769 cover the TypeScript and JavaScript forms against
Node 24.22, and errors.test.ts covers the SC2020 cases. corpus-costs.json
records their plain and sanitized costs.
