The headline

📊 The usage tools were answering into the void

usage_get read a file nothing wrote, and usage_refresh dropped a request into a directory nothing watched - then reported that data would be updated shortly. Both ends are connected now, and what the tool prints stopped overstating what it knows (#211).

🔑 The usage chip could go quiet for the rest of the session

UsageService caches a credential-store read so it does not reopen the store on every tick - on macOS each read can raise a Keychain dialog. The interval was Infinity, so one transient failure parked the account permanently: an expired token between two CLI rotations, a 401, a store that threw. No fetch was attempted again, and only restarting the app or clicking the chip escaped it (#213).

• The wait is now 5, 10, 20, 40, then 60 minutes. A usable token clears the ladder, an explicit refresh restarts it, an account switch resets it
• After eight consecutive failures the automatic retry stops rather than reopening a refused store every hour forever, which on macOS is a password prompt behind the window roughly two dozen times a day
• The tooltip names the next attempt, and says when there is not going to be one. "Waiting until 14:05" and "broken" were indistinguishable

Everything else

• Opus 5 moves to "More models", following the CLI, and stays selectable everywhere it already was - existing automations name it
• The Files viewer reads markdown three ways: rendered, source, and the session's diff when it touched the file. Plus a reload button, since the pane holds no cache and a repaint is a reload
• GPU terminal rendering is a setting, and the glyph atlas is re-cut when the font stack resolves after first paint or when the font size changes - both of those used to leave every cell drawn on the old advance widths

• "Open in editor" did nothing, everywhere in the app. spawn raises a missing binary asynchronously, and the handler had already answered { success: true }; the preload bridge was send, which discarded the answer anyway. A macOS editor whose command-line shortcut was never installed - the default for VS Code - is now found through its bundle (#216)
• "Reference in chat" needed a chat tab to already be focused, which it rarely is from the Files screen, and it attached to whatever tab was active regardless of which project you were browsing
• Rendered markdown in the Files pane used the browser's typography. The pane emitted a class no stylesheet defines
• An "Enhanced" prompt scrolled far enough back lost its original text for good. The badge bound its own listener, and a listener does not survive an entry being rebuilt from markup - the exact case the serialization allowlist exists to prevent
• A filtered table came back filtered but with an empty search box, because outerHTML keeps attributes and drops properties, and the two halves of that feature sat on opposite sides of the line
• A spinner stayed frozen after the conversation scrolled past it and back (#215)
• Changing the model twice in one turn reported a switch that never happened, and a failed switch returned to a model the session had never run
• A message queued behind a model change was handed to the CLI before the change reached it, so the next turn ran on the model you had just moved away from
• The notification toast was clipped, because the window was sized independently of the card it draws

• The release is created once, before anything builds. Each build job ran electron-builder --publish always, and electron-builder creates the release itself when it finds none for the tag. Four jobs starting in the same second all found none and two created one: v1.3.3 produced two drafts with the assets split between them, so each updater manifest described half the build. A release-ready job now fails the run if a second release appears or any expected asset is missing
• The Agent SDK moves to 0.3.280, which is what makes Opus 5.5 reachable at all - the CLI's model list is compiled into the platform binary it ships
