How does why a source marker alone cannot support a claim work in practice, and which published material supports the explanation?

How the principle works in practice (claimIndex 0). The supplied sources do not contain a passage that states or explains the principle that a source marker alone cannot support a claim. The closest relevant material is S1, which describes the general relationship between claims and evidence: "A claim is a debatable assertion or position that requires support", and "Generally, every paragraph in your paper should begin with a claim, and each claim should be supported by evidence, the proof that validates your claim". S1 also notes that when paraphrasing, you should accurately represent "The evidence used to support the claim". However, none of these passages addresses source markers specifically, nor does any supplied passage explain why a marker by itself is insufficient. S2 describes the CRAAP test for evaluating a single source's reliability (currency, relevance, authority, accuracy, purpose), and S3 discusses why trusting a claim based on its source alone can be misleading, but neither directly explains the marker-alone principle. S4 is only a browser-check page and provides no relevant content. Accordingly, this part of the question is unanswered by the provided sources.
Which published material supports the explanation (claimIndex 1). No supplied passage identifies or attributes a published work that explains why a source marker alone cannot support a claim. S3 is an essay series on key concepts for avoiding misleading claims, and it states: "In this essay, we will explain five assumptions about basing trust on the source of a claim alone". This indicates S3 addresses trust based on the source of a claim, but it does not present or cite a published material supporting the marker-alone principle as described in the question. S1 and S2 likewise do not name such a work. Therefore, this part of the question is also unanswered by the provided sources.
Overall gap. The provided excerpts do not contain a direct explanation of the principle that a source marker alone cannot support a claim, nor do they identify published material supporting that explanation. The sources touch on related topics (claims requiring evidence, source evaluation, and trust based on source), but the specific principle and its supporting literature are not covered in the supplied passages.

Sub-claim "How does the principle that a source marker alone cannot sup…": 10% covered — The gathered passages discuss claim/evidence structure (S1) and source reliability evaluation via the CRAAP test (S2), but neither explains the principle that a source marker/citation alone cannot support a claim, nor how that works in practice. S1 defines claims and evidence generally; S2 covers vertical reading of a single source's reliability. Neither addresses the specific principle. Topical context only.
Sub-claim "Which published material supports the explanation of why a s…": 10% covered — No supplied passage names or provides published material explaining why a source marker alone cannot support a claim. S1 and S2 are about evidence usage and source evaluation respectively, not about citation markers being insufficient to support claims. The skipped sources include relevant titles (e.g., Oxman PMC essay 'Trust based on the source of a claim alone', 'Ten simple rules for responsible referencing', ORI guideline on citing unread sources, 'A citation does NOT automatically make a claim supported'), but these were not read and their previews are not evidence of their content.
Both sub-claims have coverage below 0.5 (0.1 each). The gathered sources do not explain the principle that a source marker alone cannot support a claim, nor identify published material supporting that explanation. Several affordable (price 0) skipped sources directly target this gap: the Oxman PMC essay on trust based on the source of a claim alone, 'Ten simple rules for responsible referencing' (Rule 2: read the publications you cite), the ORI guideline on citing sources not read/understood, and the source stating a citation does not automatically make a claim supported. These are prioritized by direct relevance. No paid sources are needed since free options fit the remaining budget.

Final check — "How does the principle that a source marker alone cannot sup…": 80% assessed by S3
Final check — "Which published material supports the explanation of why a s…": 80% assessed by S3
Final coverage assessment — S3 directly addresses the principle that trusting a claim based on its source alone can be misleading, explaining in practice why source markers (e.g., peer review, publication, publicity) do not guarantee reliability and can mislead. S1 and S2 provide general context on evidence and source evaluation but do not explain the specific principle. S4 is a browser check page with no relevant content. The requested published material supporting the explanation is supplied by S3, which is a published essay in a series on informed health choices.
