A store with paid titles had nothing to tell this client and no way for it to listen: the catalog carried no price, no entitlement and no sign-in, so a gated download could only come back 403 and leave the window guessing why. The knowledge belongs on the server, not here. This client serves whichever catalog a registry names, so anything it knew about a particular shop would be a rule that breaks every other one. WarpEngine 0.5 answers GET /api/service with what it offers and puts an `access` block on every entry; this reads both. There is no store name anywhere in the diff. - **0.5 is a dialect of its own**, the older shape with `access` added. The version list is exhaustive over the selector, so adding it was a compile error until somebody said what it reads like — which is what that switch is for. - **A card shows a price and a Buy button** when a title is not yours, opening the store's own page. Buying stays in a browser: a checkout rebuilt here would be a second place to get card handling wrong. - **Signing in is the device grant**: a short code, the person's own browser, and no password crossing this window. The token goes in the OS keychain through safeStorage — one per store — and where no keychain exists it is not stored at all rather than written out in the clear. - **Owned / To buy** join the categories, since owning something is not the same as having installed it. Three things worth stating about the shape: The bearer token stops at the origin that issued it. A gated download redirects to signed storage — often somebody else's host — and some object stores refuse a request outright when an Authorization header arrives alongside the signature. An absent access block is not "free". It is an engine too old to have an opinion, and only one of those two is a reason to offer somebody a sign-in, so the three states are kept apart all the way to the card. state.json does not carry entitlement. Whether somebody may download a title is the server's answer to a question asked now; a copy on disk would go stale on the next purchase or refund, and a stale yes is the dangerous direction. A store with no sign-in shows none, and every WarpEngine before 0.5 is such a store: no Account block, no prices, no new categories. The smoke test against the live catalog reports exactly that — `sign-in: not offered`, `access: open:13`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

WarpEngine Client 2.4.0
The catalog can now say a title is not yours, and the client can do something about it. Where a store sells things, a card shows the price and a Buy button that opens the store's own page; where you own it, an Install as before. Two new categories go with it — Owned and To buy — because owning something is not the same as having installed it.
Signing in, without a password ever reaching this window. The side menu grows an Account block, and signing in shows a short code: your browser opens on the store's own page and you type it there. That detour is the point — a desktop application asking for a password is a desktop application people should not be giving one to. The token lives in the OS keychain (Keychain, libsecret, DPAPI), one per store, and Sign out revokes it at the server as well as forgetting it here.
None of this is knowledge about any particular store. It all arrives from the
catalog's own server: WarpEngine 0.5 answers GET /api/service with what it offers, and
puts an access block on every entry. A client that carried those facts would work for
exactly one shop — this one asks, which is why the same build serves any of them.
A store with no sign-in shows none. Every WarpEngine before 0.5 has no descriptor at all, and a 0.5 store that sells nothing reports none either. Both read as "a plain catalog", which is what this client assumed for its whole life until now, and the window behaves accordingly: no Account block, no prices, no new categories.
A title nobody has bought is not dimmed. The dimming and the dashed badge belong to what this machine cannot do — an unsupported platform, no build for this architecture — and there is nothing wrong with the machine when a title simply costs money.
A bearer token is never sent to a host that did not issue it. A gated download
answers with a redirect to signed storage, often somebody else's server, and some object
stores refuse a request outright when an Authorization header rides along with the
signature. The credential stops at the origin it belongs to; a redirect back to the
catalog keeps it.
