The agreement will always be the sole deciding factor. External data is necessary to parse exactly what the agreement entails. Is linking to the burn tax reduction proposal also violating the rules? It's external info after all. No, it doesn't work that way. External context that's necessary or useful to explain what the terms mean or entail is perfectly fine. As stated, nubcake is the one who recorded and saved this context in the first place. Asking that saved context not to be reviewed is obviously disingenuous, at least to me. Additional rules are not being added. Rule changes are not being requested. The original agreement must be enforced. It's just a matter of what - precisely - the original agreement entails.
Yes, you're right in that zazarb does not have much knowledge of the LUNC situation. DW does. To anyone familiar with the situation, the context of that term is clear. To anyone not familiar, reading the arguments/evidence provided should be sufficient to determine how the term should be followed. You need to draw a distinction between adding context/information for guidance necessary to follow the original agreement and adding new terms. Only the former is happening here, not the latter.
