Where `/ce-onboard` transfers the **as-built code** to its next maintainer, this tool transfers the **world that code serves** — to an engineer new to the product, a PM, an analyst, or anyone who must speak the product's language before they touch a file. The workflow is **read-only on code and existing artifacts**. It teaches; it never patches code, edits specs, or modifies any other artifact. The only thing it may write is one optional, consented **domain primer** — a team-internal document, never the user-facing docs that `/ce-ship-document` owns. Its epistemic contract is the load-bearing part: **a codebase is a witness to its domain, not the domain itself.** Code and recorded artifacts can evidence *what* the system enforces, *who* it distinguishes, and *what* it names. They cannot evidence *why* a rule exists, what market or regulation shaped it, or what human process wraps the software. This tool teaches the first category with citations — and hands the second to a human as a **Known-Unknowns Register**. It never narrates the unevidenced. Like `/ce-onboard`, it **o
