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 |

Leans supported
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.

The packet is filed as a QUOTE but reads as a description of a page, not the page's own words, so there is no quoted passage to verify. It also names neither Ashcombe nor the lighthouse's location, and self-describes its source as an example page. Verifying this claim needs the underlying page text with its publisher and date.

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
