The OpenAI-compatible plugin's model list sends sessionHeader too, with a fresh session ID shaped like a conversation's, since a list belongs to no conversation, and userAgent's hint and the spec say it leads the user agent, with the AI SDK's name after it on chat calls. Unticking a loaded model on a key's page takes it out of the draft, which the spec now says, along with the page's notes for a key that can't be read or isn't saved, any route answering 400 for an undecryptable key, and the Select scrolling to its active option only when it changes, each with a test and an acceptance criterion. ModelName shows a model's ID only when it differs from its name, in both the admin's and a key's list of models to tick, the admin's model rows name capabilities by their labels from the shared list, noCapabilities is typed by it, and decryptKey refuses an unreadable key in one place.

Sign in's Continue reads "Signing in…" once it is clicked, and its arrow gives way to the button's spinner, since it is leaving for the PDS rather than waiting on something it was asked to do. Coming back with the browser's back button shows Continue and its arrow again. The web UI spec makes it the one busy button that changes its label, and the test checks the new label and that the spinner is its only icon.

The chat list and its rows do less work, from an audit against React performance practice. Opening a search hides the chat list inside React's Activity rather than unmounting it, so closing the search brings the chats back as they were rather than mounting every row again. A chat row no longer holds three mutations: renaming and tagging are an EditChat card and deleting a DeleteChat card, each holding its own, so an idle row holds none, and cancelling a failed change clears its error with the card. Picking a tag keeps the rows shown until its chats arrive, rather than a skeleton between. The month headings of older chats come from two formatters made once, rather than one made for each chat on every change to the list. A reply's sources and a search's results take the fold's ref apart, so React Compiler compiles them rather than silently leaving them out. The conversation's rename, instructions, and sync call their mutations' own functions, so the header no longer renders with every state either passes through, and its jump outline is built only while the jump stack is open. The search spec says the list stays mounted, and the list test checks it is hidden.

A change to the open conversation, such as a message arriving or a reply finishing, renders again only the messages it changed, rather than every message and its actions. BranchView gives each message's row only its record, which the local copy keeps the same object while unchanged, its place among its versions as numbers and the rkeys on either side, and functions that stay the same from render to render: useChat's stop and regenerate call the mutations' own stable functions, and useModels gives the same empty list until models arrive. The reply running at the end of the branch, whose Stop the composer offers instead, reaches the Stop actions through a RunningReply context rather than the operations every action gets, so a reply starting or finishing rerenders only those. The web UI spec says so, and a ConversationView test counts each message's renders as a reply finishes.

A conversation on its way shows a few paragraphs of text lines, spaced as a reply's are, in place of one turn's bubble, name, and paragraph, which read as a chat with one message rather than messages loading. MessagesSkeleton replaces TurnSkeleton, and the shared page shows it under its title too. The page's frame, which the server sends, now holds the conversation header's row with a line for its title, so the lines start where they will once the conversation loads, rather than under the sidebar's toggle on a narrow screen. The header's row and its title on its way live in HeaderFrame.tsx, which the header and the frame share, so the frame stays free of the header's panels and menus. The web UI spec describes it.
