Charis ebd616fa90 fix(studio): auto-retry notebook updates on stale/invalid conflicts (#49323)
## Summary

- **Removed dead client-side refresh UI** in
`NotebookProposalRenderer.tsx` and its test — the diff preview is always
computed from live data, so the check was redundant with the tool's
server-side re-validation
- **Added typed `NotebookToolError`** in `notebook-tools.ts` with
structured metadata (`{ exposeToAssistant: boolean }`) validated by a
zod schema with a literal discriminant tag (`tag:
'notebook_tool_error'`) — tracks the two retryable failures: staleness
conflict and invalid operations (unknown cell id)
- **Encoded errors in `generate-v4.ts` onError** — the one place in the
pipeline that holds the live `Error` before it becomes a string in the
persisted message
- **Extracted and fixed message history filter** into new
`generate-assistant-response.utils.ts` — any tool-error whose
`errorText` decodes against the `NotebookToolError` schema is let
through (with `errorText` rewritten to plain prose so the model sees the
message, not JSON), while other errors stay filtered as before

Net effect: the assistant detects the specific, actionable rejection
reason and retries on its own with no dead button or human intervention
needed.

## Test plan

- Existing unit tests in `NotebookProposalRenderer.test.tsx` pass (dead
button test removed)
- New unit tests in `notebook-tools.test.ts` cover encode/decode
round-trips and error discrimination
- New unit tests in `generate-assistant-response.utils.test.ts` cover
message history filtering with all error states
- `pnpm typecheck` is clean
- `pnpm --filter studio run lint:ratchet` passes (no new ESLint
warnings)

Writing components

Where to create your components

  • For components that declare the general structure and layout of a page:
    • /components/layouts/xxx
  • For components that are tightly coupled to a specific interface:
    • /components/interfaces/xxx
  • For components that are meant to be reusable across multiple pages:
    • /components/ui/xxx
  • Note: We're gradually moving files out of the to-be-cleaned folder into the respective folders as we refactor

Component structure

  • If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an index.tsx as an entry point
  • Otherwise it can just be a file on its own
  • For example:
    • components/ui
      - SampleComponentA
        - SampleComponentA.tsx
        - SampleComponentA.constants.ts
        - SampleComponentA.utils.ts
        - SampleComponentA.types.ts
        - index.ts
      - SampleComponentB.tsx
      

Template for building components


// Declare the prop types of your component
interface ComponentAProps {
  sampleProp: string
}

// Name your component accordingly — use a named export, not a default export
export const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}
