Ensure terminal runtimes are started through a single in-flight start, invalidate stale async starts on destroy, and load xterm base styles before app globals while hiding helper/accessibility layers in the terminal host.
Tested: cd desktop && bun run check:desktop
Desktop startup can fail before React mounts on older WebViews, so an HTML-level watchdog now renders startup diagnostics even when the module bundle never reaches the app code. Persistent provider migration now imports legacy root provider config into cc-haha-owned storage without deleting the old source file, and plugin marketplace cleanup refuses obvious corrupted cache roots or outside paths.
Constraint: User explicitly accepted the current reviewed state for landing despite remaining review concerns.
Constraint: Global ~/.claude state is user-owned and protected; automatic repair must avoid deleting shared config, transcripts, skills, MCP, plugins, OAuth, adapters, and teams.
Rejected: Tell users to delete ~/.claude or ~/.claude/cc-haha | unsafe because it can destroy user-owned Claude state and still may not fix WebView compatibility failures.
Confidence: medium
Scope-risk: moderate
Directive: Do not weaken protected-path checks; future deletion paths should validate real paths and symlink behavior before recursive rm.

Not-tested: live macOS 12/Safari 15 WKWebView startup on an affected machine.
Not-tested: H5 diagnostic URL redaction and symlink-escape hardening are known follow-up risks from review.
