Adding a document to the knowledge base creates an ongoing maintenance task. The vendor may revise its instructions while the assistant still draws on the earlier copy. To check for those changes, the system needs to know where each document came from. I retained the original source URL when collecting the material so it could be revisited later. The ingestion pipeline prepares documents for the knowledge base by extracting their text and splitting it into searchable passages, or chunks. After this processing, a source update needs to be connected to the passages it affects. I stored the accepted version of each source alongside links to its derived knowledge. These records formed the Source Registry , giving the system both a version to compare against and a way to locate the knowledge that might need updating.

Monitoring could then revisit the original URL and compare its main content with the accepted snapshot. Normalising the content before comparison filters out differences in formatting. If the content has changed, AI reads the difference alongside the linked knowledge and assesses its significance. A changed page may contain an updated procedure, or the change may have no bearing on the guidance already held. Detecting the difference and judging its implications require different kinds of work. Because the affected knowledge is traceable, the agent can propose replacing or removing specific passages, or request further research if the changed source leaves a question unresolved. Proposed updates go through human review before the ingestion pipeline updates the knowledge and its source records together.

The next check then compares against the newly accepted version, preserving the connection between what the assistant knows and the evidence supporting it. Inside Knowledge Management Research, ingestion, and source records +
