Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:0cfa92dc-50fb-8520-8e6f-d84a660f2b35

Not yet independently audited.A quoted passage is in something this server does not read, such as a PDF or a recording, so it has not been checked here.

Why?

Strongest counted contradiction: This source describes a one-operator mixer replacing a three-to-four-worker process, not roughly one hundred workers. weight 1.800000 evidence

Suppressed as dependent: Speaker states one concrete mixing truck replaces about a hundred workers shovelling concrete.; The excerpt says one concrete mixing truck replaces about one hundred workers shovelling concrete.

Review gaps: independence reviewed, primary source reviewed

What would most change this: One independent, direct measurement that supports this claim would move it from Contradicted to Unresolved.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + -1.800000 (the counted weights) = -1.800000 → probability 0.1419

Under neighbouring settings of the same model: 0.2210 to 0.0879, a spread of 0.1331.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Passage states the claim verbatim. It is a bare assertion in conversation with no figure, study or source given, so it establishes what was said, not the ratio itself.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
