3312# Why a received context could not be forwarded unchanged:
3313#   NothingToForward{}            it keeps no received pair: its tracestate was
3314#                                 discarded when it was extracted, or it was
3315#                                 built from parts (IncomingContext.from_remote)
3316#   ForwardTooLarge{}             its tracestate fields, joined by commas,
3317#                                 exceed the tracestate output budget
3318#   InvalidForwardParent{error}   its traceparent value is not one that
3319#                                 TraceParent.read accepts
3320#   InvalidForwardState{error}    its tracestate fields are not ones that
3321#                                 TraceState.parse_fields accepts
3322# A pair that extraction keeps always passes the last two checks (law
3323# forward_extracted); they refuse a pair built directly.
