A registry record is a name and a catalog

`config` — added this morning in 2.1.0 — is gone, and `storeRepositoryUrl` with it, along
with the two store repositories they pointed at.

2.1.0 had the registry say how each store behaves. Wrong shape: how a store behaves is
fixed per installed client, and this application is the only thing that can see the
machine it runs on. A copy of that on a server was a second authority over decisions this
side had already made correctly — including which directories the store may delete from —
and two authorities are a way to disagree.

Keeping two stores on one machine apart needs none of it. It is a subfolder, derived here:
the store id is a slug of the catalog host, the home is `<id>-desktop`, the games folder is
`<id>`, and that folder is the only subtree the store will ever delete from. Derived from
the *catalog* on purpose — the catalog is what a store is, so two records naming the same
one are the same store and land in the same place, which makes installing twice idempotent
instead of a way to orphan what is already there.

Existing installations keep their identity: a store home is recognised by its own
`config.json`, so one installed as `ttg` stays `ttg` in `ttg-desktop` with its games where
they are. Only a new install derives its id.

`StoreProvisioningService` no longer re-reads the registry before installing. That existed
to keep the renderer from supplying a config, and with no config in the record there is
nothing left to protect: a name and a catalog have no paths in them.

# WarpEngine Client 2.1.0
# WarpEngine Client 2.2.0
**A store's configuration now comes from the registry itself.** `GET /api/stores`
records carry a `config` field — the same thing a store's `config.json` held, moved into
the record that already says what the store is. The client applies it directly, so
installing a store no longer depends on a second repository existing and staying
reachable, and a store can be configured entirely from the site's admin.
**A registry record is a name and a catalog.** Nothing else. The `config` field added in
2.1.0 is gone, and so is `storeRepositoryUrl` — along with the two store repositories they
pointed at, which have been deleted.
The old path still works. Where a record has no `config` but names a repository, the
client reads `…/raw/branch/master/config.json` from it exactly as before, so a registry
whose stores have not moved over is unaffected. With neither, the engine's defaults
carry the store, as they always have. The order is: registry config, then repository
file, then defaults.
2.1.0 had the registry say how each store behaves. That was the wrong shape. How a store
behaves is fixed per installed client: this application carries its own store engine and
is the only thing that can see the machine it is running on. A copy of that on a server
was a second authority over decisions this side had already made correctly — including
which directories the store is allowed to delete from — and a second authority is a way
for the two to disagree.
**The window cannot supply a store config.** It is handed stores to show and hands one
back to install, but only as an identity — the config is dropped on the way in, and the
main process reads the record again from the registry before installing anything. This
is not tidiness: a config decides where files are written and, through
`paths.subfolder`, which subtree the store may later delete from. That is not a decision
the renderer gets to make, for the same reason a `GameDto` carries no paths.
Keeping two stores on one machine out of each other's files needs none of it. It is a
subfolder, and the client derives it:
| | |
|---|---|
| **store id** | a slug of the catalog host — `teletypegames.org` becomes `teletypegames` |
| **store home** | `<id>-desktop`, under the usual store root |
| **games folder** | `<id>`, inside the OS's usual place for programs |
| **delete boundary** | that same folder, and nothing outside it |
Derived from the *catalog* on purpose: the catalog is what a store is, so two records
naming the same one are the same store and land in the same place. Installing the same
store twice is idempotent rather than a way to orphan what is already there.
**Existing installations are untouched.** A store already on the machine is recognised by
the `config.json` in its own home and keeps the identity written there — a store installed
as `ttg` stays `ttg`, in `ttg-desktop`, with its games where they are. Only a *new* install
derives its id from the catalog.
### Also
The headless check now reports *which* source configured a store — registry, repository
or defaults — and names the resulting prune boundary, because "it installed" and "it
installed where I meant" are different claims.
The public `/stores` page loses its desktop card, which advertised a `curl … | sh` for a
repository that no longer exists; an ordinary computer is served by the app. The `/desktop`
URL now lands on the app rather than on a device tab, so what someone typing it wants is
what they get.

All three configuration sources were exercised end to end against the real serializer
output, with the client's own classes and a sandbox store root:
The install path was measured end to end against a local registry serving exactly the new
record shape. The slug came out `teletypegames`, the home `teletypegames-desktop`, the
games subfolder `teletypegames`, and installing the same record twice landed in the same
home. A record carrying `config` and `storeRepositoryUrl` — what a stale registry or a
tampering renderer might still send — changed nothing on disk, because neither field exists
in the model any more.
| Registry record | What configured the store | Prune boundary written |
|---|---|---|
| `config` present | the registry, with no extra request | `teletypegames` |
| `config: null`, repository given | the repository's `config.json` | `teletypegames` |
| neither | the engine's defaults | `teletypegames` |
On this machine the check also shows both halves of the compatibility claim at once: the
registry's new slug reads `teletypegames`, while the store that was installed before today
is still found as `ttg` in `ttg-desktop`, listing its ten installed titles from
`Application Support/teletypegames`.
The renderer barrier was tested adversarially rather than assumed: an install started
from a record carrying `paths.subfolder: "ATTACKER"` and `paths.install_root:
"/tmp/pwned"` wrote `subfolder: teletypegames` and `install_root: null` to disk, because
the service re-read the registry and the mapper had already dropped the config.
The site side was migrated and its specs re-run, and the frontend was built — which first
required removing a dead `engines` list that had been failing `vue-tsc` on master, so that
page could not be built to check at all.
