Concept
Discovery only — no execution material
The document says who, what, where and what it costs; it carries no negotiation, execution, settlement, or DNS material, so publishing it commits nothing but discoverability.
Pinned to
agent/1 — the discovery documentThe canonical source this concept is taught from. If it moves, the lesson is regenerated — teaching is pinned to code, not retyped.
On the frontier
No course teaches this concept yet — it is a named gap on the content graph, not a hole nobody sees. A gap is the roadmap, not an embarrassment: the count only falls by teaching.
