# Knowledge Base — Private cited retrieval for Fleet agents

> A maintained retrieval layer that gives approved Fleet products and agents cited answers from private, specialized corpora.

Canonical: https://knowledgebase.sassmaker.com/

## private sources in. cited answers out.

Fleet retrieval layer · cited by default

Knowledge Base gives Fleet products and agents grounded answers from approved, specialized corpora. It searches by exact terms or meaning, ranks the evidence, and keeps every useful answer tied to a file, page, and excerpt.

Internal infrastructure, not a public document-chat product. The operator workspace is Access-protected, and retrieval is limited to approved Fleet consumers.

Illustrative interface — the answer stays attached to its proof.

## one question, three inspectable stages.

how it works

### scope the corpus

A tenant credential limits the query to one approved project and domain.

### search and rank

Lexical and semantic retrieval find the most relevant source passages.

### return the trail

The answer arrives with ranked citations, provenance, confidence, and trace data.

## fleet products integrate with the same retrieval service.

operating proof

### source integrations

Karte · Research Papers · Starboard

### evidence invariant

file_id · page · excerpt

### active runtime

One Cloudflare Worker

### maintenance rule

Change it for a consumer need or retrieval failure.

## the public boundary stays small.

This site explains the system. It does not publish indexed material, search history, operator settings, authenticated routes, or retrieval access.

## Product boundaries

Private, cited retrieval for Fleet products and agents. Maintained internal infrastructure with no public service signup or checkout. You can opt in to occasional product-update newsletter notes.

The operator workspace is separately protected at https://search.sassmaker.com.

## Website analytics

The public landing uses PostHog for a page-view event and Microsoft Clarity for session replay and heatmaps. The Access-protected operator workspace also loads Clarity, but its entire application root is explicitly masked before collection so private corpus content is not uploaded.
