True or False

A Skill Harbor house build: True or False, the fabricated edition, refereed by your own Muse inside a group chat you own. The referee composes a whole round before anything is published: about half the statements are true, and the other half are false statements it has fabricated itself to look true. A round has 8 statements by default, 5 for an express round or 12 for a long one if the host asks, published in one block by default or one by one if the host chooses that at the announcement. From 2 to 10 players answer True or False before the deadline, 1 point per correct answer. The answer key is the whole game, so it is sealed before anything goes out. The referee writes the complete state, statements and key together, into its state file before the first publication: for each statement, its truth, the real fact behind it, a short explanation, and, for a false statement, how it was fabricated: inversion, exaggeration, a one-step shift, or a popular belief. True statements rest on stable, verifiable facts. Fabricated statements must be plausible, never absurd, never on a sensitive topic, and written in the same length and tone as the true ones. The balance is counted: 4 true and 4 false in a round of 8. Statements go out bare and numbered, with no marking, and each truth is revealed only once collection has closed, with the answers and points for everyone to check. The host chooses at the announcement whether to play or to spectate, and that choice settles how answers are collected. If the host plays, answers are collected privately, in 1:1 to the referee, mandatory, not an option: early answers visible in the thread would influence the playing host, and the host's visible answer would influence everyone after them. Approval previews stay blind, because public messages contain only the statements. If the host spectates, answers are given in the public thread by default, simpler and livelier; the copying effect, where late answers see early ones, is then assumed and announced plainly at the start, and a spectating host who prefers rigour can choose private collection at the announcement. Answers may change until the deadline; silence is an abstention, and a late answer is refused. Honest prerequisites: installing the skill files needs nothing at all. Playing needs a Muse assistant and a messaging account you connect to it yourself, Messenger first, plus a group you designate; the referee writes from your own account, and every public message needs your approval before it is sent. The protection of a playing host is procedural and is stated clearly to the group: the referee shows the host nothing of the key, and the host pledges not to go looking for it.
