The review's critical: Decimal(repr(value)).normalize() read the process-global
decimal context, so a legitimate program setting getcontext().prec = 2 silently
rounded the completion value's digits and traps[Inexact] = True made the encode
raise, misclassifying a successful run as an exception. A fixed module-level
Context(prec=28) makes the spelling decision context-independent; a regression
case mutates both context knobs and asserts the float round-trips exactly.
The binding-reply README entry now states the fact (no seam-level cap;
maxValueBytes meters only the done frame; a wide reply is rebuilt and encoded
whole, bounded by process memory), matching the earlier reviewer wording.
