   Thanks for the clear repro, I could reproduce this on 2.0.27.

   With your .opencode/plugins/bad-model.ts in a project, opencode run "hi" fails right away with undefined is not an object (evaluating 'rH.time.released'). In the TUI, model loading for the directory breaks: after sending a message, no models are available and the "Connect an integration" dialog opens. The same setup without the plugin works normally. My run only opened a new session, so I didn't see the "Session location unavailable" modal itself; it likely shows when an existing session is reopened, as you describe.

   The TUI problem still happens on the latest dev (a22754f), and the time.released sort in Model.snapshot is unchanged there. The recording, screenshot and script below show the TUI side. Until this is handled, building the model with Model.Info.default(...) as you noted avoids it.

   Related but different causes of the same modal: #49352, #43415.

   Reproduction script (drive.ts)

   import { Effect } from "effect"
   import { OpenCodeDriver } from "opencode-drive"
   
   // Plugin from #54943: registers a model without `time` via editor.add
   const plugin = `import { Plugin, Provider } from "@opencode/plugin";
   export default Plugin.define({
     id: "bad-model",
     async setup(ctx) {
       await ctx.provider.transform((editor) => {
         editor.add({
           info: { ...Provider.Info.empty("bad-model"), name: "Bad", activation: "enabled" },
           models: [{
             id: "bad-model.m1", providerID: "bad-model", modelID: "m1", name: "M1",
             capabilities: { tools: true }, limit: { context: 1000, output: 1000 },
           } as any],
         });
       });
     },
   });
   `
   
   export default OpenCodeDriver.use(
     {
       ...(process.env.OC_DEV ? { opencode: { dev: process.env.OC_DEV } } : {}),
       project: { git: true, files: { ".opencode/plugins/bad-model.ts": plugin } },
       tui: { recording: true },
     },
     ({ ui }) =>
       Effect.gen(function* () {
         yield* ui.screenshot("start")
         yield* Effect.sleep("3 seconds")
         yield* ui.submit("hi")
         yield* ui.waitFor("Session location unavailable", { timeout: 60000 } as any).pipe(
           Effect.catch((e) => Effect.log(`waitFor failed: ${e}`)),
         )
         yield* Effect.sleep("2 seconds")
         yield* ui.screenshot("result")
       }),
   )

   Run it with opencode-drive: opencode-drive run ./drive.ts. It drives opencode from your PATH; set OC_DEV to the path of an OpenCode checkout to run that from source instead.
