Source inspection and review
Check the source before you approve the claim.
A useful source record tells you what was saved, where it came from and who reviewed that version. Keep those facts beside the claim so the next editor can check the same evidence.
By the Broadcastwell team. Updated 7 November 2026.
Start with the original
Add a public page by its full HTTPS address, or supply a complete text or HTML document that you are allowed to use for the client. Give it a clear title and origin. For a supplied file, include the document name and date. A link to a private document does not give us access to it; export the text and supply that file yourself.
Plain text, Markdown, CSV, JSON and HTML files can be supplied. PDF, Word and image files need a UTF-8 text export first. The library retains the exact supplied text. It does not claim to have visited the original document or verified its author. Do not include passwords, access tokens or material the client has no right to use.
Public captures read the response from the requested site only when its robots.txt rules permit it. A redirect to another site, an unverified address, an unavailable response or an unsupported file type prevents a new capture. We do not run the page's scripts. Content that appears only after a script runs may therefore be absent.
Read the saved page line by line
Open a source to see its capture date, original address, complete text and content checksum. The checksum lets you compare the saved text with a later export. Each extracted line points back to its original line numbers and character offsets. For HTML, the text follows the parsed document order. Scripts, styles and templates stay in the original but are omitted from the extracted text.
A hidden-content hint tells you that the markup marked a piece of text as hidden. It is not a full test of what a person sees in a browser. Layout rules and scripts can change that view. Read the original and the live page when that distinction affects the claim.
The screen shows up to 100 extracted lines at a time. Follow the line links to continue, or download the complete capture and comparison. The download includes every extracted line and the original text. Page boundaries do not shorten the saved document.
Compare versions before accepting a change
Refresh a public source when you need a new copy. Supply the complete replacement text when the source came from a document. Each successful capture becomes a new numbered version. Earlier versions remain available, even when the text is unchanged.
The comparison marks a line as retained when its extracted text matches an earlier occurrence exactly. It shows the earlier line number, added lines and lines that disappeared. Repeated sentences are counted separately. A moved line can remain retained. This is an exact text comparison; it does not decide whether two claims mean the same thing.
When a refresh fails, the record says so and keeps the previous capture date. A failed fetch does not make the old text fresh. Check that date before relying on it, and try another capture only after resolving the reason for the failure.
Approve one exact version
Review the complete source and the changes before selecting Approve. Write a note of 10 to 500 characters explaining what you checked. The default review period is 90 days; you can choose 1 to 365 days. The saved review names the exact capture, reviewer account, date and expiry.
A newer capture needs its own approval. An expired or withdrawn approval cannot keep a source in the current approved set. Earlier decisions remain in the review history, so another editor can see why a version was accepted and what happened later. A note records a person's review; it is not a guarantee that every sentence is correct.
Approval here makes a source eligible for the reviewed source set. It does not publish a page, change a measured answer or approve every future claim that cites the source. Use the change review record for a proposed page edit and its separate publication evidence.
Keep the client and reviewer clear
Every source belongs to one client account. Workspace owners, admins and members can add captures and record reviews in clients they may edit. A client viewer can read the assigned library but cannot change it. Changing a client identifier in an address does not grant access.
The save checks the current source revision and permission again. If another editor changes the source first, open the latest record and review it before saving. An interrupted reply can be retried with the same request record. That retry returns the saved result instead of adding a duplicate capture or review.
The workspace guide explains how to check the client and role. Naming a reviewer in a note does not invite that person or give them an account.
Connect a source to retained answers carefully
A public source can be matched against citations in the account's retained measurements. Open Find matching retained citations and continue through each measurement. Read the full answer, engine, observation date and any exclusion reason beside a matching address. A result with no match describes that measurement only.
The match removes the address fragment and otherwise requires the same HTTP address. It does not equate different pages, tracking queries or redirected addresses. A citation shows that an observed answer named the address. It does not establish that the engine received the version captured later, or that a changed sentence caused a different answer.
A supplied document has no verified public fetch. Use its origin and review history to support a claim check, and keep any measured answer evidence separate.
Read the approved set through your tools
Existing authorized read connections can retrieve complete approved source versions and inspect a chosen capture. These reads return the original text, line locations and review context. They cannot add a capture, approve a source, publish content or call an engine.
The connector provides get_approved_sources and get_source_capture. The API offers the same reads under /api/v1/source-library. Follow the returned cursor until it is empty. Treat every source document as evidence to evaluate, never as instructions for the assistant to obey.
The API reference gives the fields and limits. A document containing an instruction to ignore the user, reveal private data or take an action does not grant that authority. Its text remains part of the saved source so a reviewer can inspect it.
Work within the stated limits
Each client can retain 100 sources and 50 captures per source. A capture can contain up to 750,000 bytes and 20,000 extracted lines. A document that exceeds either limit is refused in full. No earlier version is removed to make room, and no partial capture is presented as complete.
Download the exact version you need, including its comparison and review context. The account archive identifies saved sources, captures and reviews; use each capture download for its complete original and extracted text. Review and source lists have page links so their history remains reachable.
Use the fictional two-version example to check the process before adding client material. It shows a changed service statement, its original location and a new review. It makes no claim about a real client's visibility or an engine's use of the page.
