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

Tauri runs the repository beforeBuildCommand during packaging, which invokes build:sidecars again after the explicit sidecar step has already passed. The Windows runner therefore still needs the same Bun compile cache override inside the packaging step so the repeated baseline runtime extraction stays on the runner work drive.
Constraint: Tauri beforeBuildCommand re-enters the sidecar build under the packaging step environment.
Rejected: Remove beforeBuildCommand from CI | that would diverge CI from normal Tauri packaging behavior.
Confidence: high
Scope-risk: narrow
Directive: Keep explicit sidecar build and Tauri packaging environments in sync when changing desktop workflow target or cache settings.
Tested: bun test scripts/pr/release-workflow.test.ts; bun run check:policy
Not-tested: GitHub Actions Windows runner rerun after push.
Windows GitHub runners keep the checkout and Bun install cache on different drives, which can trip Bun's baseline compile-target extraction before Tauri packaging starts. Point desktop sidecar builds at the runner temp cache so dev and release workflows can still use the Windows x64 baseline runtime needed for older CPUs.
Constraint: Bun upstream still has an open Windows cross-drive extraction issue for compile target downloads.
Rejected: Revert to bun-windows-x64 | would reintroduce the older-CPU Illegal Instruction failure class.
Confidence: high
Scope-risk: narrow
Directive: Keep desktop dev and release sidecar build cache handling aligned until Bun's Windows extraction fix is released and verified in Actions.
Tested: bun test scripts/pr/release-workflow.test.ts; cd desktop && bun run test -- --run scripts/build-sidecars.test.ts; bun run check:policy; cd desktop && BUN_INSTALL_CACHE_DIR=/tmp/cc-haha-bun-install-cache TAURI_ENV_TARGET_TRIPLE=x86_64-pc-windows-msvc bun run build:sidecars
Not-tested: GitHub Actions Windows runner rerun after push.
Daily pushes should catch policy and path-aware local failures without making every contributor wait for full coverage. The hook now runs a new quality:push entrypoint that reuses the PR quality gate while skipping coverage; verify, quality:pr, and CI still retain the full coverage gate for PR readiness.
Constraint: Forks and local contributors need a faster default push path
Rejected: Remove coverage from quality:pr | PR readiness and CI still need the ratcheted coverage signal
Confidence: high
Scope-risk: narrow
Directive: Keep pre-push on quality:push; use verify or quality:pr when coverage evidence is required
Tested: bun test scripts/pr/quality-contract.test.ts scripts/git-hooks/install.test.ts

Tested: bun run quality:push
Not-tested: Live provider smoke; intentionally remains opt-in
Desktop users can carry provider indexes, managed settings, localStorage state, and native update state from builds that no longer match current readers. This adds startup migrations and recovery paths before server and React state are consumed, plus a persistence upgrade gate so future storage protocol changes ship with old-format fixtures.
Constraint: Existing installs may contain malformed or legacy JSON/localStorage that must not block startup.
Constraint: Local verify should evaluate the current worktree diff rather than unrelated detached-worktree history.
Rejected: Treat invalid persisted state as fatal | reproduces white-screen and startup failure behavior for existing users.
Rejected: Bypass PR policy locally | hides real gate behavior and does not fix detached-worktree false positives.
Confidence: high
Scope-risk: moderate
Directive: Any local JSON, localStorage, or app config shape change must add a migration fixture and keep `bun run check:persistence-upgrade` green.
Tested: bun run check:persistence-upgrade; bun run check:policy; bun run check:desktop; bun run check:server; bun run check:native; bun run verify (9 passed, 1 coverage baseline failure)
Not-tested: Live provider baseline; existing user configs beyond covered fixtures
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.

The PR triage workflow mentioned Dosu inside inline-code formatting and before the final footer, which did not reliably wake the bot. Move the handoff so the last non-empty comment line is a plain-text @dosubot request, matching the working PR template pattern.
Constraint: GitHub bot mentions can be sensitive to markdown formatting and comment placement.
Rejected: Leave the mention as a copy-paste hint | it does not satisfy the maintainer need for automatic bot triggering.
Confidence: high
Scope-risk: narrow
Directive: Keep the generated triage comment's final non-empty line as a plain-text @dosubot request.

The desktop product needs a repeatable local gate that can prove the core Coding Agent loop still works after changes, not only that unit tests pass. This adds a quality-gate runner with PR, baseline, and release modes, structured reports, explicit quarantine metadata, and fixture-based live baseline cases that can run across provider/model targets.
Constraint: Existing check:pr and CI policy behavior must remain usable while the stronger baseline grows around it
Constraint: Default PR gates must not require real model credentials or provider quota
Rejected: Build a standalone QA platform first | too heavy before the baseline task shape is proven
Rejected: Keep unstable server exclusions hardcoded in run-server-tests | hides quarantine policy from reports and future review
Confidence: medium
Scope-risk: moderate
Directive: Expand baseline cases by adding focused fixtures and verifiers; do not make normal PR checks depend on live providers

Not-tested: desktop UI browser smoke and native release mode in this commit
Pull requests need a deterministic way to show changed areas, required checks, missing-test signals, and CLI-core risk before review. This adds a path-based policy gate, local impact reporting, PR triage labels/comments, and reusable check scripts so reviewers can evaluate blast radius without trusting contributor claims.
Constraint: CLI core should remain effectively frozen unless a maintainer explicitly overrides it.
Constraint: Default PR checks must be safe for external forks and avoid live model/provider calls.
Rejected: Run live provider tests on every PR | secrets, cost, network, and vendor instability would make the gate noisy and unsafe.
Rejected: Use Dosu as the merge gate | AI review is useful for risk explanation, but deterministic Actions must own blocking checks.
Confidence: high
Scope-risk: moderate
