Corpus size
Why this page exists
This entire corpus — 8 million words across 470+ documents — was generated by Claude, an AI model. AI models hallucinate. They invent plausible-sounding people who never existed, assign real people to wrong parties, confuse dates, and fabricate quotes. Some of these errors made it into the published archive.
We believe transparency about these failures is more valuable than pretending they don't exist. Every confirmed error is documented below: what went wrong, how it was caught, and what was done to fix it.
If you find an error in the corpus, please report it below. Every report is reviewed. Confirmed issues are added to this registry and fixed in the archive.
How we prevent hallucinations
Corpus grounding
The chat assistant only answers from retrieved corpus documents. It is instructed never to supplement with its own training knowledge.
Name verification
Every person name in chat responses is checked against the corpus context. Ungrounded names trigger automatic re-generation.
LLM audit layer
A second AI call audits every response for factual claims not supported by the provided context documents.
Confidence disclaimers
When grounding verification fails twice, responses are marked with a disclaimer warning users to cross-reference.
Corpus-level auditing
Systematic cross-document audits check for internal contradictions, fabricated profiles, and inconsistent facts across the archive.
Community reporting
Users can report suspected errors directly from this page. Every report is reviewed and confirmed issues are fixed.
Known Issues Registry
Every confirmed hallucination, factual error, and fabricated profile found in the corpus.
Entirely fabricated minister profile
A full biographical profile was generated for "Dhana Pillai" described as a "Pioneer of Indian-Singaporean Political Representation." The profile contained no specific dates, no constituency, no verifiable facts. The person does not appear in any parliamentary roster or other corpus document. Classic AI hallucination: plausible-sounding but entirely void of verifiable content.
SG-H-CS-06 (Gunasekaran Krishnasamy)
Entirely fabricated civil servant profile
A full biographical profile was generated for "Gunasekaran Krishnasamy" described as a senior Indian-Singaporean civil servant. Coverage period listed as "Mid-twentieth century–present" (absurdly vague). No specific dates, positions, agencies, or achievements. Reads as a generic essay about minority civil servants, not a biography of a real person.
David Marshall's party misidentified as People's Progressive Party
The text referred to David Marshall's "People's Progressive Party." Marshall led the Labour Front, not the PPP. The PPP was D.R. Seenivasagam's party in Perak. The book correctly identified Marshall's party as Labour Front elsewhere but used the wrong name here.
Lee Siew Choh misidentified as a journalist
The text called Lee Siew Choh "The veteran Singapore journalist." Lee Siew Choh was a medical doctor and politician (Dr. Lee Siew Choh, Chairman of Barisan Sosialis). He was likely conflated with Said Zahari, who was an actual journalist detained during Operation Coldstore.
Chan Choy Siong mischaracterised as Barisan Sosialis
The text described Chan Choy Siong as "a Barisan Sosialis politician." Chan Choy Siong was a PAP MP for Delta constituency who championed the Women's Charter. She was not a Barisan Sosialis member.
"Seow Peck Leng" and "Mrs Lim Yew Hock" listed as PAP women MPs
Two names — "Seow Peck Leng" and "Mrs Lim Yew Hock" — were listed as "PAP women MPs in the early Parliament." Neither name appears in any parliamentary roster. "Mrs Lim Yew Hock" is especially dubious since Lim Yew Hock was a political opponent of the PAP.
Unverifiable civil servant profile with vague dates
Profile of a "colonial transition civil servant" with birth listed as "c. 1920s" (vague). The profile acknowledges "the scarcity of detailed biographical information." While referenced in other corpus documents, the person cannot be independently verified and the profile contains no verifiable specific facts.
Minister for Culture claim contradicts Cabinet records
The profile lists Chiang Hai Ding as "Minister for Culture" from 1959. However, Cabinet records in SG-I-01 and SG-C-13 list S. Rajaratnam as Minister for Culture in the first PAP cabinet. While the book referenced (A History of Straits Settlements Foreign Trade) appears to be a real publication, the ministerial claim is contradicted by other corpus documents.
MacDonald House bombing victim names fabricated
Two of the three MacDonald House bombing victims were incorrectly named. The document listed "Juliet Goh Ah Neat" and "Lim Tua Tow" — the correct victims were Suzie Choo Kway Hoi (a secretary), Juliet Goh Hwee Kuang (a clerk), and Mohamed Yasin bin Kesit (a driver). "Lim Tua Tow" is a fabricated name that does not appear in any historical record of this event. The error appeared three times in the document.
SG-C-15 (Nicoll Highway Collapse)
Three of four Nicoll Highway collapse victim names fabricated
Three of the four Nicoll Highway collapse victims were incorrectly named. The document listed "Hossain Md Joynal", "Rahim Khan", and "Arulnathan Manian" — all fabricated. The actual victims were Heng Yeow Pheow (LTA foreman), John Tan Lock Yong (LTA engineer), Liu Rong Quan (construction worker), and Vadivil s/o Nadesan (crane operator). Heng's name was also misspelled as "Peow" instead of "Pheow" and his role was wrong.
NCMP voting restrictions described as current when removed in 2017
The document described NCMPs as unable to vote on constitutional amendments, supply bills, and motions of no confidence — presented in the present tense as current law. However, a 2016 constitutional amendment (effective 1 April 2017) gave NCMPs equal voting rights to elected MPs. The error appeared in multiple sections of the document.
