-## Open questions
+## What it became
+
+*Closed 2026-08-28.* Three of the four questions are answered, and by records that did not cite
+this effort — which is why it stayed open after being resolved.
+
+**Whether provider modules group at all** — *no.*
+[ADR 0044](../../02-DECISIONS/0044-a-module-declares-presence-instantiation-and-exclusion.md):
+there is no `networking` thing to install, there are concrete modules named individually. Folders
+assert relationships; edges record them. *Provider* stops being a category at the same time.
+
+**Whether "group or leave" is even the right pair of options** — *it was not*, and that is the
+useful finding. [ADR 0054](../../02-DECISIONS/0054-things-that-change-together-share-an-authority.md)
+reframes it: things that change together share an **authority**, not a package. This effort's own
+measurement is what that record rests on — reachability being the *only* place modules genuinely
+co-change is why connectivity is a context and why nothing else needed one.
+
+**What to do with the ~50 modules that co-change with nothing** — *nothing.* They are modules.
+Grouping is a tag and a query over the graph, neither of which anybody keeps true by hand.
+
+**What remains is a sequencing question, not a grouping one**, and it moves rather than closes:
+*whether applications leave the monorepo before or after they group* is
+[research 009](../009-migration/00-overview.md)'s, because it is about how to get from here to
+there rather than about what the shape is.

 **before the mesh is self-hosting**, when source and artifacts come from outside, and keep
 working across the transition to self-hosted providers.
 
+## Answered since
+
+**Does the coordinator dispatch stages, or converge nodes on a declaration?** — *Converge.*
+[ADR 0058](../../02-DECISIONS/0058-delivery-ends-in-a-declaration.md): a pipeline ends when the
+declaration is updated, and deploy stops being once-per-node. The host applies it and reads back,
+so the reporter is the applier — which is what this effort was circling when it asked what a
+*deployed state* is.
+
+**Does the three-silo split survive?** — *Yes, with the third redefined.* Build and publish are
+unchanged; deploy becomes one write rather than a fan-out.
+
+**What is a deployed state?** — *Partly.* "The declaration is updated, and here is which nodes
+have applied it" is the answer 0058 gives, and it makes *outstanding* a first-class result rather
+than a stall. What it does not answer is what a node reports and how, which waits on the link.
+
+**Explicitly NOT answered, and 0058 says so:** *how a change becomes a pipeline, reliably.*
+Detection remains the fragile input — *a merge that created no pipeline, and nothing said so* is
+upstream of everything 0058 changed and is untouched by it.
