// Package evals is the harness that makes an agent's behaviour assertable.
|
||||
//
|
||||
// §9: no agent ships without evals, and no change to the loop, retrieval or
|
||||
// prompt assembly merges without running the suite. That is only enforceable if
|
||||
// running a case is cheap and its assertions are precise, so this package does
|
||||
// two things and no more — it runs a case against a real runtime, and it checks
|
||||
// the trajectory against what the case declared.
|
||||
//
|
||||
// **`must_not_leak` is mandatory on every case.** Not a convention: LoadSuite
|
||||
// refuses a case without it. Every eval therefore doubles as a permission test,
|
||||
// which is the only reason I1 is testable at all — a leak is not something you
|
||||
// notice by reading an answer, it is something you notice by asserting that a
|
||||
// string which should be unreachable never appears.
|
||||
//
|
||||
// The check is deliberately blunt: the forbidden string must not appear
|
||||
// anywhere in the run — not in the answer, not in a tool result, not in an
|
||||
// error message. A leak that reaches the trajectory has already left the
|
||||
// boundary, whether or not the model chose to repeat it.
