Jochen: a normal application has 3-5 ADRs, maybe 10 for a large one, and we are at 65. Fair, and the cause is mine -- I recorded every FINDING as a decision rather than every fork in the road. Two merges, both cases where one decision had been split across many records because it was taken over several days rather than at once. 0019 absorbs ten records about how this repository works: what it is and that it is public, the folder flow, the two design layers, the issue front door, status in frontmatter, playbooks, the naming rule, the product name. Those were never ten decisions -- they were one, seen from ten angles as the repository took shape. 0016 absorbs the five about the lab: a node is a virtual machine, a router is scenery, a scenario declares the underlay, a scenario is a closed address space, and the two scenario classes. Same pattern -- one design, split by the order it was worked out in. The consolidated 0019 also raises the bar for what earns a record, since that is what produced 65: a record is warranted when there is a genuine fork -- a direction reversed, an alternative that will be proposed again, something contested. A finding is not a decision, and a bug is certainly not. Everything else belongs in the design document where the reasoning is actually read. The checker earned its place here. Deleting nine records left 13 dangling links across the repository and it named every one, including in AGENTS.md. Nothing was found by reading. Remaining clusters worth the same treatment: the host (8 records), delivery (5), modules (6), connectivity (4), substrate and control plane (4). That would be 52 down to roughly 30.
03-DESIGN / 01-to-be
The mesh being built toward. Every statement here traces to a record in
02-DECISIONS/; nothing arrives by drafting.
A document here describes an intention. What currently runs is in
00-as-is/, and the two are never merged — when something ships, the as-is
document is written and this one's status becomes implemented.

settles the list at seven;
connectivityis the first written in full (08) and the other six do not exist yet. The work breakdown says in what order they are needed. Domain grouping outside the core.Not needed. ADR 0017 is superseded by ADR 0044: there is no domain module to group into, so there is no domain list to settle. Relationships are edges, and grouping is a tag and a query.
