Anatomy

When an answer depends on which documents the model read: memos, reconciliations, due diligence, anything a lender or auditor will check.
When people steer the model by narrowing what it reads rather than by rewriting the request.
Not for a quick answer from one source. Name the source in the answer instead (Trace).

Change	What happens	What waits
Hover or focus a source	The sentences that rely on it are underlined in pigment	Nothing is read again
Remove a source	Sentences that relied on it are struck through and counted	The rewrite, until you choose Redraft
Add a source	The budget grows; sentences that can use it again are flagged	The draft, as written
Run over 100%	The lens turns ochre and the model says it will skim	Nothing is removed for you
Redraft	Only flagged sentences stream again, as one job Brake can pause	Unchanged sentences keep their acceptance
Accept	The redrafted sentences settle into still pigment	Nothing

Aperture never trims the view on its own. When the budget runs over, it says what will happen and leaves the choice to the person.

Name each source with its scope and when it was read: “June valuation report · pages 4–19 · read 4 min ago”.
Show each source’s share of the budget as a number, not only as a bar.
Flag before you rewrite. The person decides when the draft changes.
Keep Add and Remove person only. The model can suggest a source; it can’t widen its own view.

DoShow what the model reads, with each source’s share, beside what it wrote.

Don’tDon’t hide the sources behind a count. People can’t tell what the memo rests on.

The budget lens is an image labelled with the share in use; the overflow warning is a polite live region.
Each remove button names its source: “Stop reading June valuation report”.
Focusing a source marks the sentences that rely on it, the same as hover.
Flagged sentences are struck through and counted in words, not marked by colour alone.
