# Source Verification: Check Your Claims Against the Web

> After the reasoning analysis, Fracture searches the public web for your factual claims and builds starter citations for well-matched results.

After the reasoning analysis finishes, Fracture runs a separate source pass on your draft. It pulls out your factual claims, searches the public web for each one, and returns a support status along with starter citations for the claims it can match. The goal is to give you a starting point for building your bibliography and flag the claims that need more work before they can carry weight in your argument.

## How It Works

**1. Claim Extraction**

The engine pulls out quoted passages, the claims it flagged during the reasoning analysis, and factual-looking sentences from your draft.

**2. Public Web Search**

For each extracted claim, Fracture searches public pages and retrieves page text to compare against your claim.

**3. Match Scoring**

The retrieved pages are compared against your claim and assigned a support status based on how closely the page's content matches.

**4. Citation Building**

For well-matched claims, Fracture builds a starter MLA or APA entry from the matched page's details. Your citation format preference is set in Settings.

## Support Statuses

| Status | Meaning |
| - | - |
| **Likely supported** | A retrieved page closely matches the claim |
| **Partial match** | Part of the claim matches, but not every detail is confirmed |
| **Needs review** | Pages were found but do not clearly support the claim |
| **Citation incomplete** | The draft does not name the source precisely enough |
| **Source not found** | No usable public result was returned |

## How to Read Results Well

* **Treat "likely supported" as "worth opening," not "verified"** — a high match score means the page discusses the same subject in similar terms, not that your specific claim has been proven.
* **For any load-bearing claim, open the source and read the passage yourself** — do not rely on the match status alone when the claim carries real weight in your argument.
* **Prefer primary sources, official data, and reputable publications** over aggregators and secondary summaries.
* **If a claim is flagged "citation incomplete" or "vague," name the source precisely in your draft and re-run the check** — the engine needs enough specificity to find the right page.

## What a Match Does and Does Not Mean

* A match means the page discusses the same subject in similar terms — not that it proves your specific claim or supports the exact conclusion you attached to it.
* A match does not confirm the page is accurate or authoritative — a reputable-looking result can still be wrong or outdated.
* A match does not check the methodology or credibility of a study the engine finds — evaluating the quality of the source is your responsibility.

## Citation Format

Fracture builds starter citations in either MLA or APA format. Set your preferred style in **Settings** before running an audit, and the source-verification summary and exported bibliography will use that format throughout.

> Always open any linked source and confirm the exact passage before using it in a final paper or speech. Every match is tentative — the source check is a starting-point finder, not a fact-checker.
