+content = """\
+Severity and likelihood are different questions, and a finding needs both \
+answered before it can be labelled. A defect that would be serious but that no \
+plausible input reaches is not the same as one a user hits on a normal Tuesday, \
+and a review that files both under the same banner tells the reader nothing.
+
+The test is one question, asked before anything else:
+
+**Can you name an input a JP user plausibly produces that triggers this?**
+
+Plausible sources include: text the model emits, bytes a tool returns, values a \
+user might reasonably put in a config file, files in the repository being \
+worked on, arguments passed on the command line, and the states a long-running \
+session can reach by ordinary use.
+
+Not plausible: adversarial payloads (JP's threat model is the user's own machine \
+and accounts, not an untrusted network attacker), inputs drawn from a domain \
+outside the project's audience, and states the type system already prevents.
+
+Answer it inside the finding. "A tool that returns more output than the buffer \
+expects" is a named input. "A value constructed to hit this branch" is a \
+construction, not an input — if that is the best you can do, say so plainly and \
+label the finding accordingly.
+
+The point is not to suppress findings. Post them. The point is that whoever \
+triages has to be able to tell, without re-deriving it, which findings gate the \
+merge and which are recorded for completeness.

+tag = "Review Severity: Does It Stay Put, Will They Notice"
+content = """\
+Once an input is named, two properties decide whether the finding gates a merge.
+
+**Does the damage stay put?** Contained means the wrong behavior affects only \
+the operation under review, and the next operation starts clean. Spreading means \
+it escapes: a half-written file that later reads back wrong, a panic that takes \
+the command down, a leaked process or lock that outlives the request, a wrong \
+value that feeds unrelated computation, formatting state that bleeds into \
+everything printed after it.
+
+**Will the user notice?** Visible means they can see something is wrong and \
+retry, work around it, or report it. Hidden means they cannot: a swallowed \
+error reported as success, silently dropped data, a config layer that never \
+applies, a plausible-looking wrong answer.
+
+A finding gates the merge when a plausible input produces damage that spreads or \
+hides. Anything contained and visible is a suggestion, however unappealing the \
+output is.
+
+That second category is where review threads go to die. Each round finds a \
+narrower case than the last, each fix is small in isolation, and the tests \
+quietly grow past the code they cover. Contained and visible means the user gets \
+a worse result and can tell — that is an acceptable outcome, not a defect to \
+chase to perfection.
