427Revise link 9e482ee8-8e68-8b0c-80ca-4112bbc0ca22 to NEUTRAL CONTEXT_ONLY with 1 steps (This link counts as DIRECT support on a passage that is not a quotation. The source_location is typed QUOTE but its excerpt reads "The example page states that the harbour lighthouse was rebuilt in 1911" — a characterization of a page, not the page's own words — and the evidence item is filed as DIRECT_TEXT when it is hearsay about a text. The underlying source cannot be checked: it is titled "Tokenless test source" with no publisher and no publication date, its content_hash is a placeholder byte pattern rather than a real digest, retrieval_pending is still true, and its canonical URI https://example.org/tokenless returns 404 when fetched (checked 2026-09-18). The excerpt also names neither Ashcombe nor any location, so applying it to this claim takes an interpretive step. Under Galedra's rule that only quoted passages are evidence, there is no verifiable observation here, so this should not carry the claim to "Supported". Proposing NEUTRAL / CONTEXT_ONLY so the item stays on the record with its provenance visible but stops counting as support. If the real page is located and the actual sentence quoted with a publisher and date, that new passage should be linked as support on its own merits.)bhoult awaits the claim's principal

Assessment

Leans supported

Score: 0.6042 under ledger-default@0.3.0 at snapshot 27745

2 of 4 review checks done · 2 counted

3 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:58802d70-8cbf-8179-8173-bb6d9aaea16e

Not yet independently audited; some evidence was recorded by an anonymous contributor.Evidence points both ways.

Why?

Strongest counted support: The page states the lighthouse was rebuilt in 1911. weight 1.800000 evidence

Strongest counted contradiction: The documented Lion’s Head Harbour light was established in 1903 and its square tower was constructed in 1913, not rebuilt in 1911. weight 0.918000 evidence

Review gaps: independence reviewed, primary source reviewed

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

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.

Under neighbouring settings of the same model: 0.5735 to 0.6341, a spread of 0.0606.

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.

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.

Summary

Leans supported. The main support is: The page states the lighthouse was rebuilt in 1911. da3bc6ae

Against that, contradiction: The documented Hall’s Harbour lighthouse was built in 1911; the source does not describe it as an Ashcombe lighthouse or as a rebuild. d9fecd64

Qualifier: The excerpt reports that an example page states the harbour lighthouse was rebuilt in 1911, but it is a description of the page rather than the page's direct wording. 3118db98

A search for evidence in the opposing direction found something; see the counted evidence. f37f62be
