Resolves the outstanding review comments on [#495]. Opened against pre-main because [#495]'s head is pre-main - commits cannot be pushed onto it directly, so fixes land here and flow into that promotion.

Of the 11 inline comments on [#495], 5 were already fixed by [#496] (self-referential workflow comments, contents: write scoping, ${{ }} shell interpolation, the placeholder-overwrite bug, the duplicated detect_install_mode). Those threads are stale and resolved. This PR covers the 4 that were not, and re-declines 2.

The one that matters: my own [#500] fix was incomplete

merge-windows-updater.py sets PYTHONIOENCODING=utf-8 in the workflow, which covers stdin/stdout/stderr only. Path.read_text() and Path.write_text() fall back to the locale encoding - cp1252 on the Windows runner this script runs on.

So [#500] fixed the in the success print and left the file I/O exposed to the identical failure one line away. A single non-ASCII character in latest.json and the read dies, in the script whose entire job is to not corrupt the manifest macOS auto-update depends on. Encoding is now pinned on all three operations.

Good catch by the reviewer, and a fair one against me.

Invoke contracts moved to ui/lib/api-types.ts

InstallOutcome was defined in LlmProviderPicker.tsx. Per the repo rule, Rust-mirrored invoke response types live in api-types.ts so they cannot drift from src/llm/detect.rs unnoticed.

Moved all four (InstallOutcome, ProviderStatus, ProviderTestResult, ProviderTestOutcome) rather than only the one flagged - the review listed the siblings as candidates, and moving one of four would leave exactly the split the rule exists to prevent. The picker re-exports them so the existing import sites in steps.tsx and LlmProviderDetail.tsx keep resolving.

Spans on the LLM install paths

install_provider and cursor_sign_in shell out to vendor installers - real work, and the observability guideline requires a span with an explicit failure status, not just tracing::info! lines.

Both are now instrumented, recording ok and the resolved cli_path. The neat part: install_failed is the single funnel every failure path in both functions returns through, so recording on the current span there marks whichever is running as failed without threading a span handle through a dozen early returns.

Shared test helper

sourceOf and stripComments were near-identical comment-stripping helpers in two suites. Extracted to __tests__/helpers/source.ts.

Not taken, with reasons

  • Pinning dtolnay/rust-toolchain@master to a SHA. It appears in all seven places across every workflow in the repo. Pinning one file is inconsistent rather than safer. The review cites a blanket repo policy, but nothing in .github/workflows is pinned today - so this is a real repo-wide change, and it deserves to be one.
  • Loosening the placeholder heuristic. value_is_set rejects anything containing your-, _your_ or -here, which can in principle reject a valid Jira URL. But the failing examples are contrived, and tightening the rule is a product judgement about what a real credential looks like - not something to settle inside a review-fix PR.

Verified

  • [x] cargo clippy --all-targets -- -D warnings clean
  • [x] 258 UI tests pass, 130 Rust tests pass
  • [x] ui production build succeeds; no typecheck errors in the touched files
  • [x] Merge script re-tested: happy path writes windows-x86_64 with darwin entries byte-intact; error path prints its real message
