A definition names no host path (ADR 0112); an adopted machine keeps its
data where the predecessor put it. Two settings, validated like endpoints:
places: {<directory id>: <path> | {path, owner}}
accesses: {<access id>: <path>}
An access may now be declared by id (`{"id": "series", "mode": "read-write"}`)
and named in mounts, env and content as ${access:<id>}; the assignment
says where it is on this node, and an access nobody placed is refused by
name. A definition still carrying a path keeps it as the default the
assignment replaces. A placed directory takes the assignment's owner
where it says one. Resolved in composition, so the host receives paths
and owners exactly as before.
Three of novox/hq's group-4 leftovers, one branch.
Issue 173: a module's settings reached every route it contributed, every database it asked for and
every served fact its consumers read — a mail server's site name arrived at the proxy as a route
fact. A setting now overrides a key a contribution or served fact declares and adds none; a file
still merges any key, and a key nothing takes is named as stray instead of dropped silently.
Issue 174: the mesh's own files for a module — its bus credential, its merged config, its bindings —
were placed by the definition under /var/lib/mesh/<module>, 232 host paths in 50 definitions. A
directory may now say `place: "mesh"` and resolves to <root>/mesh/<module>; a directory beneath a
placed one may state its path as `${dir:<id>}/<rest>` and moves with it. The proof test resolves
both catalogues and compares: 48 definitions, no path moved. The controller's own manifest is
converted here; the catalogue in mesh-catalog.
ADR 0155: the installation check moves to registration. `module add` and a build's result both
refuse a definition that names an installation, in the check's words, with the way out; the build
stays recorded.
Slice two of ADR 0112. A pathless directory saying place "." is the
assignment's one directory, <root>/<module> — to-be 27's shape — and
place never reaches the host, which parses strictly. The maps naming
where bindings, credentials and contributions land (binds, secrets,
own-secrets, receives, grants) fill against the placed directories at
composition, into fresh maps and a fresh module slice, because one
resolution composes for many nodes. The five absolute-path checks on
those maps accept a placed reference — resolution makes it absolute
before anything reads it — while certificate, operator-keeps and
accesses paths stay absolute-only: those are the operator's or another
vocabulary's. unknownDirRefs scans the maps too, and validates place
itself: only on a directory, only ".", never beside a stated path.
Found by the foundation tests validating the sibling catalogue: the
first conversion's blanket replace turned /var/lib/gitea/database.json
into ${dir:data}base.json — which resolves to the right path by pure
string concatenation. Production was saved by a coincidence; the
catalogue cleanup that follows spells it ${dir:state}/database.json.
The first executable slice of ADR 0112 / to-be 27, sized to what the
operator settled tonight: a module definition names no host path for
its own data. A directory resource may omit path; composition resolves
it to <root>/<module>/<id>, the root a node's setting on Rendering with
/var/lib as the default — which reproduces exactly the layout novox
converged to by hand. ${dir:<id>} names the place from a resource's
path, content, mounts, environment and env-files, the same shape as
${bound:…}. A directory that states a path keeps it and still answers
by name — that is the adopted-data placement, mssql its live case.
Resolved in the controller at composition, so the wire format and the
host change not at all; a reference naming no directory refuses at the
manifest and again at composition; nested fills are rebuilt, never
written into the manifest's own maps, because one manifest composes
for many nodes.
