Begin with what supports a claim
Evidence gives a statement somewhere to stand. A source may be a document, an observation, a record, or an explicit account from the person concerned. Each supports particular claims and leaves other questions open. The design principle behind Atlantis is to preserve that relationship between a conclusion and the material that justifies it. A source should be relevant to the question, understood in context, and treated with appropriate care when circumstances have changed. Clear reasoning begins by asking what the evidence actually establishes. This gives the person a way to examine the answer, challenge its basis, and decide how much weight to place on it.
Keep interpretation visible
Evidence often requires interpretation. Two records can describe different parts of the same event, and a plausible explanation can still leave important alternatives open. Atlas's evidence philosophy makes room for that uncertainty. A direct record, an inference drawn from it, and an opinion about what to do next occupy different roles. Keeping those roles visible helps a person assess where agreement exists and where judgment begins. It also makes disagreement more productive. You may accept the underlying facts while rejecting the recommendation, or question a source while finding the reasoning useful. A well formed account should let you locate that difference precisely and respond to it.
Correction belongs in the record
Understanding develops through correction. A source can be superseded, an assumption can fail, or the person involved can supply context that changes the interpretation. Atlantis places correction alongside evidence because an account of the world needs a way to improve. The important questions are practical: what changed, why it changed, and which conclusions depend on the earlier view? Preserving those relationships helps prevent an obsolete assumption from quietly shaping later work. It also supports an honest archive, where an earlier decision can be understood in the circumstances of its time. The aim is reasoning that remains open to inspection throughout the life of an agenda.
