0054 -- things that change together share an authority, not a package.
The constitution instructs agents to group "how a node is reachable" into one
module, citing superseded ADR 0017; ADR 0044 says there is no networking thing
to install. Since the constitution is injected where work is decided, the
superseded rule is the one actually steering work. The observation behind it
was right -- research 005 measured that reachability is the only place modules
genuinely change together -- but the conclusion was wrong: tight coupling means
a shared authority, not one artifact. wireguard and traefik deploy to different
node sets, so the merged module would be assigned where half is unwanted.
Requires amending how-we-build and republishing the derived page.
0055 -- the control plane is the node-coordinating contexts.
Three context lists were in circulation (0015 says nine, 06 says ten, the
README said eight) and none was decided. Research 006 said explicitly that the
change "belongs in a new record -- not written here", and the design used the
list anyway. Reconciling them shows `stream` and `ai` were dropped with no
reasoning at all. Applying 06's own test -- needs to know about more than one
node -- gives seven contexts plus the api, with work, knowledge and stream as
hosted applications and `ai` folded into config as an ordinary grant. The
record defers rather than lists.
The cost is stated rather than reassured away: a board composing across the
boundary reads more than one interface. That was raised before as "only moves
the problem up a layer", and the answer is that 0045 already requires surfaces
to read interfaces rather than stores -- what changes is the count, not the
kind of work.
0056 -- the authority is the control plane, not a database.
Every clause of 0003 has been decided against in four separate records and it
is still accepted and cited as live. The error underneath is the same category
error 0054 corrects: "source of truth" named a storage location when it meant
an authority, and once the store is the answer, shared schemas follow. The
half that was right -- the repository defines what exists, the mesh defines
what runs where -- survives untouched. Best consequence: the cache mode
disappears, so a node that has not heard from the mesh is no longer
indistinguishable from one that has.
0003 is left accepted until 0056 is.
