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.
Tested: bun test src/utils/plugins/installedPluginsManager.test.ts src/utils/plugins/marketplaceManager.test.ts
Tested: bun run check:server
Tested: cd desktop && bun run test -- --run src/main.test.tsx index-html.test.ts vite-config.test.ts src/theme/globals.test.ts
Tested: cd desktop && bun run build
Tested: bun run check:coverage
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.
Contributors and coding agents need one local command that both reports and enforces the quality contract. This change turns the PR gate into the shared verification entrypoint, adds path-selected local lanes, tightens coverage accounting around changed lines, and documents the repair loop in contributor and agent-facing guidance.
Constraint: Ordinary PR verification must stay non-live and runnable without provider credentials
Constraint: Coverage policy updates in this commit require maintainer approval before push/merge
Rejected: Keep quality guidance only in docs | agents need executable scripts and AGENTS.md instructions to follow the loop consistently
Confidence: high
Scope-risk: broad
Directive: Do not bypass `bun run verify` for production changes; fix failed lanes and coverage reports instead of lowering thresholds
Tested: bun run check:policy
Tested: ALLOW_CLI_CORE_CHANGE=1 ALLOW_COVERAGE_BASELINE_CHANGE=1 bun run verify
Not-tested: live provider baseline; no provider credentials were required for this non-live PR gate
The desktop app now keeps the composer stable while turns are active,
reduces low-signal tool noise in the transcript, restores project context
under the composer after session creation, and relies on the CLI's own
permission requests instead of injecting broader desktop-side Bash asks.
This also brings in the supporting desktop app source tree and the server
routes/session metadata needed for git info, filesystem browsing, session
resume, slash commands, and SDK-backed permission bridging so the UI can
operate as a coherent feature instead of a partial patch.
Constraint: Desktop transcript needs to stay usable during long multi-tool sessions without hiding file-change diffs
Constraint: Permission prompts must mirror CLI behavior closely enough that read-only commands do not get desktop-only prompts
Rejected: Keep rendering Read/Bash bodies inline | too noisy and unlike the intended transcript model
Rejected: Commit only the touched desktop files | would leave the newly introduced desktop app incomplete in git history
Confidence: medium
Scope-risk: broad
Reversibility: messy
Directive: Treat non-writing tools as summary-first transcript events; do not re-expand them by default without validating the UX against long sessions
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test -- --run
Tested: bun test src/server/__tests__/conversations.test.ts
Not-tested: Manual visual regression against the exact screenshots in a live desktop session
Not-tested: Full root TypeScript check (repository still has unrelated extracted-native parse failures)
