Two replies telling us to cut off contact

Civilisational assumption
All people, institutions, events, figures, and future technologies in every issue are a synthetic premise. Background documents are sources for topic discovery and are not evidence of future facts or probabilities.
The question to decide
Two responders from the same direction of one star system each claim to represent the other side and demand that we end communication with it. A neutral reply can be read as hostility, and waiting for confirmation can mean the contact is lost. Which response will the participating Earth institutions choose: a single public answer, holding all promises in reserve, or limited commitments on separate channels?

The options
The order shown is not a ranking of preference.
The situation as it stands
It assumes that two interpretable replies have arrived from the direction of the same stellar system. Decision deadline: 1 year until the next joint transmission window.
Fictional interstellar contact community
- Premise 1It assumes that two interpretable replies have arrived from the direction of the same stellar system.
- Premise 2The two responders each claim to be a legitimate representative and demand an end to contact with the other side.
- Premise 3Further confirmation takes a long time, and differences in communication technology do not mean political representativeness.
Where it holdsSet commitments on external contact and public disclosure for participating institutions. It cannot settle the counterparty civilization's representativeness or the actions of every transmitter on Earth.
What is still unknown
- Unknown 1Whether the two replies come from separate groups or from a single test
- Unknown 2The way the other side understands the words representative and commitment
Signals to decide again
- Set what observations, responsible parties, and confirmation windows will confirm 「whether the two replies come from separate groups or from a single test」, and reassess when new confirmation changes the tradeoffs among the options.
- Set what observations, responsible parties, and confirmation windows will confirm 「the way the other side understands the words representative and commitment」, and reassess when new confirmation changes the tradeoffs among the options.
Where the paths partNot answers — paths that part from the same starting point
One responder quotes the contents of an unpublished message from the other side.
Independent observation confirms differences between the two transmitters' locations and signaling methods.

What is an irreversible connection, and what does an exchange without a common language presuppose?
An exploratory perspective chosen by the creator. Does not claim supernatural validity or the superiority of any particular option.The benefits and costs of the options accrue to different stakeholders. Which loss to accept remains undecided.
