- NoThrow diagnostics name compiler-resolved Node errors (class and message)
and explain parameters the frontend compiles as T | undefined because a
caller passes a possibly missing value (for example xs[i]!), naming that
call.
- Synthetic dynamic-class helpers (%dyn.*) carry the location of the code
that first needed them; they are no longer bound to annotations there.
- Int32 hints only parenthesize where needed; the NoThrow hint no longer
suggests try/catch, which does not discharge the contract.
- Diagnostics snapshots and TypeScript preflight/order baselines for the new
fixtures.
- Docs: /docs/contracts and a limitations entry.
