Introduce the Electron desktop shell alongside the existing React renderer and local Bun server boundary. The migration keeps the DesktopHost contract explicit across Tauri, Electron, and browser runtimes while adding Electron main/preload services for dialogs, shell, notifications, updates, tray/window lifecycle, terminal, preview WebContentsView, app mode, and release/package validation.
The commit also carries the latest local main desktop command updates, including agent slash entries and hidden-by-default markdown thinking details, so the packaged Electron build matches the current main UX surface.
Constraint: React renderer, local Bun server, REST/WebSocket, and sidecar boundaries must remain reusable during the migration
Constraint: macOS dev packages are ad-hoc signed and cannot prove Developer ID notarization or Gatekeeper release launch
Rejected: Browser-only smoke validation | it cannot exercise native dialogs, keychain prompts, notification behavior, or packaged app startup
Confidence: medium
Scope-risk: broad
Directive: Do not remove Tauri host support until signed Electron release artifacts pass native OS smoke on macOS, Windows, and Linux

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 repository now has a measurable PR quality path instead of a loose set of
manual checks. Coverage, quarantine governance, provider smoke, desktop smoke,
and workflow wiring all produce durable reports that contributors and maintainers
can inspect without reconstructing terminal output.
This also fixes the desktop smoke current-runtime path so browser-driven smoke
runs use the desktop default active provider instead of forcing the official
current model, and records that runtime decision as an artifact.
Constraint: Default PR gates must remain non-live and contributor-safe while live model checks stay explicit.
Constraint: Release packaging is still GitHub Actions based, so release preflight must run before the build matrix.
Rejected: Make live provider or desktop smoke mandatory on every PR | secrets, quotas, and model availability are maintainer-controlled.
Rejected: Let PRs lower coverage baselines in the same change | base-branch ratchet comparison must remain authoritative.
Confidence: high
Scope-risk: moderate
Directive: Do not relax coverage or quarantine policy without a maintainer approval label and a fresh quality report.

Tested: git diff --check
Not-tested: Full live release mode with multiple providers in hosted CI; provider credentials and quota remain maintainer-controlled.
The live baseline covered the server WebSocket path, but it still did not prove the desktop app can open a session, apply a selected provider/model, send a chat turn, and surface model/tool progress through the UI. This adds an agent-browser driven smoke lane that starts the local server and Vite desktop app, restores an isolated session tab with the requested runtime selection, submits a small coding task through the composer, and accepts the run only when the fixture diff and tests pass.
Constraint: Desktop smoke must stay behind --allow-live because it launches browsers and real models.
Constraint: The smoke temporarily enables bypassPermissions for the isolated run and restores the previous mode afterward.
Rejected: Wait for a final marker phrase | model reasoning and echoed prompts can contain the same marker before the work is actually done.
Rejected: Use only DOM text as success proof | the browser can show progress while the project files are still unchanged.
Confidence: high
Scope-risk: moderate
Directive: Future desktop smoke cases should verify project state and artifacts, not only UI copy.

Not-tested: Kimi desktop smoke completion because the provider returned AccountQuotaExceeded / API Error 429 until its reset window.
