### `verify_references`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Fact-check a document's REFERENCES and CLAIMS — built for AI-generated reports whose
    citations must be checked before they're trusted.

    USE THIS WHEN someone shares a report, article, whitepaper, or deep-research export (or a
    link to one) and asks: is this accurate / legit? are these citations real? fact-check this.
    did the AI make this up? Also use it proactively before relying on any AI-written document.

    Provide the document ONE way: `url` (a public http(s) link to a PDF or web page — fetched
    server-side, the cheapest call: no need to download or encode anything), `text` (pasted
    markdown/plain prose), OR `bytes_b64` (a base64 PDF; URLs are read from the PDF's link
    annotations, so they're exact). Default (fast): provenance (is it a ChatGPT deep-research
    export?), citation resolution (live / archived / dead, papers matched against arXiv/Crossref
    to catch 'real ID, wrong paper'), and internal MATH (recompute the doc's own arithmetic).
    Set `deep=true` to also fetch each cited source and judge whether it SUPPORTS or CONTRADICTS
    the claim (slower, ~a minute).

    Returns a trust summary, per-item tables, and a shareable `permalink` to the public
    fact-check record. HONEST BOUNDARY: this reports verification COVERAGE, not truth —
    'supported' means evidence-backed (not necessarily true) and 'unsupported' means no evidence
    found (not necessarily false). It tells a reviewer WHERE to look; it does not bless the
    document, and it never affects the fraud risk band.
    
```
