# Trust Depth Over Data Volume: An Independent Audit of LUX Light Archive

Story ID: `trust-depth-over-data-volume`
Language: `en`
Story type: `place_cluster`

## Narrative Angle

An external, AI-assisted audit found LUX Light Archive's defining trait to be 'trust depth over data volume': every claim carries confidence, review status, and a source link, and complex identity transformations are modeled as typed relationship graphs rather than free text. This article adapts that audit into our own evidence-linked format, pointing every claim at the live Heritage Journey it describes.

- 1920 - modified - LUX-ASSET-000625 -> LUX-PLACE-000010: Electrification date is uncertain: Persée records 1920; Fichou inventory cites 1924. Both remain open pending primary document review.
- 1940 - demolished - LUX-ASSET-000625 -> LUX-PLACE-000010: Fichou inventory records that the feu was extinguished in 1940 after median construction in front; port embankment works continued to transform the castle-foot shoreline.
- unknown - installed_at - LUX-ASSET-000626 -> LUX-PLACE-000011: The Vasilisin wooden tower stood on Ostrov Vasilisin in Lake Onega; construction date is unknown in the archive.
- 1858 - manufactured_by - LUX-ASSET-000238 -> LUX-PLACE-000005: The imported Pencarrow Head Chance Brothers asset is modeled as a second-order fixed lens manufactured in 1858 for the upper Pencarrow lighthouse system.
- 1859-01-01 - installed_at - LUX-ASSET-000238 -> LUX-PLACE-000015: Pencarrow Head’s permanent lighthouse was first lit on New Year’s Day 1859 and is treated as the installation context for the root Chance lens/light system.
- 1859-01-01 - commissioned - LUX-ASSET-000238 -> LUX-PLACE-000015: The upper Pencarrow permanent light entered service as New Zealand’s first permanent lighthouse.
- 1906 - commissioned - LUX-ASSET-000630 -> LUX-PLACE-000016: Lower Pencarrow was erected below the cliffs in 1906 for fog/cloud conditions and as a companion day mark with the upper light.
- 1935 - navigation_function_transferred_to - LUX-ASSET-000238 -> LUX-PLACE-000017: After the automated Baring Head light became operational in 1935, Pencarrow’s upper light was no longer the main approach light and was used solely as a day mark. This relation models navigational-function succession, not physical relocation of the Pencarrow optic or tower.
- 1935 - commissioned - LUX-ASSET-000631 -> LUX-PLACE-000017: Baring Head became operational in 1935 as the new automated light serving the Wellington Harbour approach.
- 1966 - transferred_to - LUX-ASSET-000238 -> LUX-PLACE-000015: The lighthouse was transferred to the New Zealand Historic Places Trust in 1966 after it was no longer required as a navigational aid.
- 1974 - restored - LUX-ASSET-000238 -> LUX-PLACE-000015: A significant restoration project was completed between 1974 and 1980 by the Ministry of Works and Development at NZHPT request.

- 1858 - installed_at - LUX-ASSET-000632 -> LUX-PLACE-000015: The Pencarrow Head tower kit arrived in Wellington in 480 packages in 1858, was transferred to Pencarrow Head, hauled up to the site, and was ready for the first lighting on 1 January 1859.
- 1806 - part_of - LUX-ASSET-000634 -> LUX-LH-000624: The physical station fabric is the built manifestation of the single canonical Clare Island Lighthouse station.
- 1806 - part_of - LUX-ASSET-000635 -> LUX-ASSET-000634: The original 1806 tower is one historical component of the Clare Island station fabric.
- 1818 - part_of - LUX-ASSET-000636 -> LUX-ASSET-000634: The replacement lantern tower is the second tower generation within the same station fabric.
- 1818 - part_of - LUX-ASSET-000637 -> LUX-ASSET-000634: Keeper dwellings and associated buildings form part of the station complex.
- 1806 - built - LUX-ASSET-000635 -> LUX-LH-000624: The original Clare Island tower was established as the station's first lighthouse in 1806.
- 1806 - commissioned - LUX-ASSET-000635 -> LUX-LH-000624: The original lighthouse entered service in 1806 to mark the entrance to Clew Bay.

- 1818 - built - LUX-ASSET-000636 -> LUX-LH-000624: A replacement lantern tower was built beside the retained original tower in 1818.
- 1818 - functionally_replaced_by - LUX-ASSET-000635 -> LUX-ASSET-000636: The 1818 lantern tower assumed the lighting function of the fire-damaged 1806 tower without erasing the older structure.
- 1818 - commissioned - LUX-ASSET-000636 -> LUX-LH-000624: The replacement lantern tower entered service toward the end of 1818.
- 1914 - modified - LUX-ASSET-000634 -> LUX-LH-000624: Irish Lights records refurbishment of the Clare Island light in 1914; optic manufacturer, model and later custody remain unverified.
- 1965-09-28 - decommissioned - LUX-ASSET-000634 -> LUX-LH-000624: Preferred official assertion: Clare Island Lighthouse was extinguished at sunrise on 28 September 1965.
- 1965-09-29 - decommissioned - LUX-ASSET-000634 -> LUX-LH-000624: Alternative secondary assertion: a lighthouse-accommodation history gives 29 September 1965. It is retained for provenance but does not displace the official Irish Lights date.
- 1965-09-28 - operationally_replaced_by - LUX-LH-000624 -> LUX-LH-000625: Achillbeg became the operational successor when Clare Island's light was extinguished; the Clare Island structures did not move.
- 1965-09-28 - navigation_function_transferred_to - LUX-LH-000624 -> LUX-LH-000625: The navigational responsibility transferred from Clare Island to Achillbeg. This relation is conceptual and must not render as physical movement of a tower or station.
- 2008 - modified - LUX-ASSET-000634 -> LUX-LH-000624: After private acquisition in 2008, the preserved complex was renovated and adapted for hospitality accommodation; access is by booking, not unrestricted public entry.
- 1962 - carried_light - LUX-LS-000001 -> LUX-ASSET-000629: Irbenskiy carried a documented composite light and signal installation, including the AGA RD-311 light apparatus, MRM-54 radio beacon and LIEJ-300 nautophone; this equipment remains distinct from the vessel identity.

- 1830 - located_at - LUX-ASSET-000639 -> LUX-PLACE-000022: La Coubre's station mandate continues on the changing coast; the mapped point represents the current site only.
- 1830 - part_of - LUX-ASSET-000641 -> LUX-ASSET-000639: The 1830 timber light is the first reviewed generation in the La Coubre succession.
- 1842 - replaced_by - LUX-ASSET-000641 -> LUX-ASSET-000642: The timber tower was succeeded by a masonry light with keeper accommodation.
- 1860 - replaced_by - LUX-ASSET-000642 -> LUX-ASSET-000643: Coastal erosion forced a return to a timber scaffold.
- 1895 - replaced_by - LUX-ASSET-000643 -> LUX-ASSET-000644: The timber scaffold was succeeded by a masonry tower.
- 1905 - replaced_by - LUX-ASSET-000644 -> LUX-ASSET-000645: The current reinforced-concrete tower was lit inland before the predecessor collapsed.
- 1907 - destroyed - LUX-ASSET-000644 -> LUX-PLACE-000022: The 1895 masonry tower collapsed into the sea in March 1907; exact historical coordinate remains unresolved.
- 1830 - historically_part_of - LUX-ASSET-000639 -> LUX-LH-000619: The signal lineage links the successive La Coubre structures to one navigational identity.
- 1869 - located_at - LUX-ASSET-000658 -> LUX-PLACE-000024: The Roches-Douvres station identity remains anchored to the same offshore plateau across two materially different towers.
- 1869 - historically_part_of - LUX-ASSET-000658 -> LUX-LH-000255: The station lineage carries the reviewed Roches-Douvres lighthouse identity across destruction and reconstruction.
- 1869 - part_of - LUX-ASSET-000659 -> LUX-ASSET-000658: The prefabricated metal tower embodied the Roches-Douvres station from 1869 until its wartime destruction.
- 1944-08 - destroyed - LUX-ASSET-000659 -> LUX-PLACE-000024: German forces destroyed the occupied metal lighthouse in August 1944; the reviewed official sources do not establish 4 August as the exact date for this station.
- 1954 - replaced_by - LUX-ASSET-000659 -> LUX-ASSET-000660: The destroyed metal tower was replaced by the present granite-and-concrete lighthouse after seven years of offshore construction.
- 1954 - part_of - LUX-ASSET-000660 -> LUX-ASSET-000658: The present granite-and-concrete lighthouse carries the continuing Roches-Douvres station identity.
- 1947 - built - LUX-ASSET-000660 -> LUX-LH-000255: Construction of the replacement began in 1947 and continued for seven years, using granite dressed and numbered on shore before shipment to the reef.
- 1954-06 - commissioned - LUX-ASSET-000660 -> LUX-LH-000255: Preferred public assertion at month precision: POP records the present lighthouse as lit in June 1954. This supports the Story's 1954 milestone without selecting a disputed exact day.
- 1954-06-19 - commissioned - LUX-ASSET-000660 -> LUX-LH-000255: Alternative official assertion: the DIRM 2025 lighthouse guide gives 19 June 1954. It remains visible in Research but does not silently override the month-level editorial choice.
- 1954-07-14 - commissioned - LUX-ASSET-000660 -> LUX-LH-000255: Alternative official assertion: the public DIRM lighthouse page places the lighting in the night of 13-14 July 1954. The anniversary framing remains evidence, not an uncontested exact date.
- 1843 - located_at - LUX-ASSET-000661 -> LUX-PLACE-000025: The lighthouse identity is rooted at the reviewed Zmiinyi Island site.
- 1843 - historically_part_of - LUX-ASSET-000661 -> LUX-LH-000141: The site lineage carries the archive lighthouse identity across physical change and loss.
- 1843 - part_of - LUX-ASSET-000662 -> LUX-ASSET-000661: The 1843 fabric is one historical state of the lighthouse-site lineage.
- 1843 - built - LUX-ASSET-000662 -> LUX-LH-000141: The reviewed historical record dates construction of the lighthouse to 1843.
- 2002 - part_of - LUX-ASSET-000663 -> LUX-ASSET-000661: The restored pre-2022 installation is a later physical state of the same site identity.
- 2002 - restored - LUX-ASSET-000663 -> LUX-LH-000141: Extensive restoration and capital repair modernised the lighthouse in 2002.
- 2022 - destroyed - LUX-ASSET-000663 -> LUX-LH-000141: The Ukrainian national report records complete destruction of the lighthouse and its infrastructure.
- 2026-07-07 - documented_by - LUX-ASSET-000661 -> LUX-ASSET-000664: The official postmark turns the absent lighthouse into a documented memorial image.
