Codex Desktop App 26.609.30741 (0.140.0-alpha.2): local sessions disappear after update until renderer cache is cleared

Description
After Codex Desktop App auto-updated to 26.609.30741 (bundled codex-cli 0.140.0-alpha.2), all previous local sessions disappeared from the sidebar. The session files are still present on disk.

Environment

• Codex Desktop App: 26.609.30741 (CFBundleVersion 3808)
• Bundled codex-cli: 0.140.0-alpha.2
• OS: macOS 26.5.1 (Apple Silicon)
• Auth: ChatGPT login

Observed behavior

• Sidebar shows no previous sessions after update.
• ~/.codex/sessions/ still contains 101 rollout JSONL files.
• ~/.codex/state_5.sqlite still contains 643 thread rows (85 unarchived, 558 archived).
• Rebuilding ~/.codex/session_index.jsonl from state_5.sqlite and restarting the app does not restore the sessions.
• Switching model_provider back to openai and restarting does not restore the sessions.
• App logs show: failed to refresh available models: unexpected status 403 Forbidden: ... Missing scopes: api.model.read ... url: https://api.openai.com/v1/models?client_version=0.140.0

Workaround that restored the sessions
Clearing the Desktop App's renderer cache and restarting restored the sidebar history:

rm -rf ~/Library/Caches/Codex \
       ~/Library/Caches/com.openai.codex \
       ~/Library/Application\ Support/Codex/Default/Cache \
       ~/Library/Application\ Support/Codex/Default/Code\ Cache \
       ~/Library/Application\ Support/Codex/Default/GPUCache \
       ~/Library/Application\ Support/Codex/Default/Session\ Storage

Expected behavior
All existing local sessions should remain visible in the Desktop sidebar after an update without manually clearing caches.

Steps to reproduce

1. Have existing local sessions created before the update.
2. Update Codex Desktop App to 26.609.30741.
3. Open the app.
4. Sidebar shows no previous sessions.
