Supported

Score: 0.9734 under ledger-default@0.3.0 at snapshot 27745

2 of 4 review checks done · 2 counted

2 independent evidence lineages · review checks 2 of 4 · stability HIGH

Main unresolved issue: 5 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:c1614f70-183a-8347-a699-f6f0c549b770

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 support: Apple TV lists “Return to Tomorrow” as season 2, episode 20 of Star Trek: The Original Series. weight 1.800000 evidence

Suppressed as dependent: The excerpt identifies Return to Tomorrow as season 2, episode 20 of the original series.; A speaker identifies the clip as season 2, episode 20 of the original series, Return to Tomorrow.

Review gaps: independence reviewed, primary source reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Supported.

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 + 3.600000 (the counted weights) = 3.600000 → probability 0.9734

Under neighbouring settings of the same model: 0.9255 to 0.9908, a spread of 0.0653.

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.

Season, episode number, series and title all match the claim exactly. It is a spoken identification of a clip rather than a reference to an episode guide, so the numbering rests on the speaker.
Return to Tomorrow is the twentieth episode of the second season of Star Trek, first broadcast 9 February 1968.

From Return to Tomorrow Read 2026-09-20 Relevance DIRECT Steps 0 Counted

Season and episode number match the claim exactly, and the same page's episode box gives Season 2 Episode 20 with an air date of 9 February 1968. This is a tertiary source reporting broadcast order; the episode's production code is 051, so a guide numbering by production order rather than air order could place it differently.
The excerpt identifies Return to Tomorrow as season 2, episode 20 of the original series.

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.
