The delivery repository's contracts and SDK live under modules/ as mesh-delivery-contracts and mesh-delivery-sdk, their Go module paths renamed to match the folders (the TypeScript names already did), and every importer in mesh-delivery, mesh-catalog, mesh-host, mesh-tools and mesh-sdk follows in the same group: a design as it should be, one path per module, checked by the group's check building every importer.

// Package ends is the teller's recovery tool teller_end_ask and the value it writes (issue 774; the instruction "tools are
|
|
// how a module is spoken to"). An ask the teller holds open at the router keeps one of the three places the router gives
|
|
// its asker (asks.MostOpen) until it is answered, it lapses, or the gate or the assigner takes its key away. When that last
|
|
// never comes (on 2026-10-31 two merge asks of pull requests merged by another path held two places for a day, and a
|
|
// assignments ask was refused for want of room), a person ends the ask by hand. The teller's process serves no request
|
|
// subject (ADR 0437 §4), so the tool writes an end into the teller's state ends, which the teller watches, carries out
|
|
// and answers there, as the indexer answers indexer_take_in.
