Research efforts move from status.md to 00-overview.md with active / graduated / abandoned, matching papa-hq so the two repositories read the same way. Playbooks, skills, README and the ledger follow. Reverses yesterday's withdrawal of the symlink note in GENESIS. The note was right and the withdrawal was wrong: the intent is that the mesh creates no symlinks at all, so a founding document listing "symlinks, not copies" as a design principle does point the opposite way from where this is going, and that is a contradiction rather than a stale detail. ADR 0018 records the position, proposed. ADR 0011 stays as it is — it is the historical decision and the incident behind it is why anyone believes either record — and is superseded in intent, not edited. Its one editorial line, which called the wider reading false, is corrected to state what is actually true: centralising who may link narrowed the incident class without closing it, because a link the installer makes resolves exactly like one made by hand. The argument that kept linking was staleness. ADR 0004 removed it: every managed file is already derived and reconciled, so a copy is the natural form and a pointer into source is the shape the mesh's own model forbids everywhere else. What is not settled, and is marked open, is how staleness gets detected — which is the decision that makes or breaks it.

004 — Reproducing the mesh network in a lab
- Initiated by: jochen, 2026-08-22 — "the most difficult part of our VM setup will be the networking part"
- Areas touched:
modules/wireguard,modules/dnsmasq-app,modules/traefik,modules/mesh-ca,node_accessors,nodes.site/nodes.underlay_addr.
Summary
The network is entirely generated from mesh-DB rows by module hooks. install.d performs
no network configuration whatsoever — no WireGuard, no DNS, no firewall. That makes a faithful
lab primarily a data problem rather than a networking problem, and means the lab exercises
the real code path instead of a reimplementation of it.
One constraint decides whether the lab works at all: the WireGuard endpoint rule tests the
underlay address against an RFC1918 regex to decide reachability. A simulated public segment
addressed from RFC1918 space silently prevents the mesh from forming — no endpoint is written
for the hub, so nothing can ever initiate. The simulated public segment must therefore use
TEST-NET-3 (203.0.113.0/24).
With that one substitution the lab reproduces the production topology exactly, including the case that is hardest to get right: a node that is publicly named but sits behind NAT, whose endpoint the hub can only learn from a handshake.
Detail in analysis.md.
Settled
The lab issues its own certificates. Public names are certified by an ACME server on the
lab's wan segment; .internal names keep the mesh CA. The lab preserves production's two-CA
split rather than collapsing it, because a single-CA lab would hide any bug living in that
split. It also makes the router's port forward load-bearing — HTTP-01 must reach the
published-but-NATed node on port 80, so a broken forward becomes a reproducible certificate
failure instead of a mystery.
Requires one change: caServer is not set on the reverse proxy today, so it defaults to the
public authority's production endpoint. It must become configurable, defaulting to
production so real nodes are unaffected.
