Who it is for

The 'why is it built this way' question gets asked daily and answered by archaeology. Xerum answers it with a citation and a revision.

Every new engagement re-answers questions the firm already answered. The record is the only thing that outlives the team that made it.

The first market where agents genuinely need to write. Proposals are how they do it without anyone losing control of the knowledge base.

You already run this process by hand. Citation and editorial sign-off are the two properties the store enforces by construction.

Citation is an obligation, partner review is already 'members propose, owners decide', and privilege demands physical isolation. Three properties, all built.

Research memos, deal history and IC decisions, in a store where the record cannot be rewritten after the fact.

Traceability is already a legal obligation. A curated append-only record maps onto the audit culture rather than fighting it.

Need-to-know is a pre-filter inside the query; physical isolation per customer is the deployment story you already mandate.
