Task 01: Save Coordinator and Navigation Guard

Acceptance

• Settings descendants can register stable dirty contributors and one fixed action saves all valid dirty contributors in stable order with revision-safe partial-failure handling.
• The action is hidden when clean, accessible on desktop/mobile, uses safe-area offsets, and does not cover the final page controls.
• Dirty in-app/history navigation offers Save and leave, Discard and leave, and Continue editing; reload/external exit installs a native warning.

Verification

cd apps && pnpm --filter @kandev/web test -- --run components/settings/settings-save-provider.test.tsx components/settings/settings-layout-client.test.tsx components/routing/app-link.test.tsx lib/routing/client-router.test.ts
cd apps/web && pnpm run typecheck

Inputs

• Spec: What, State Machine, Failure Modes, navigation and mobile Scenarios.
• ADR 0042.

Output Contract

Report registry API, save ordering/error semantics, navigation behavior, rendered mobile checks, tests run, files touched, blockers, and update this task plus plan.md.

Result

• Added a keyed contributor registry with stable ordering, validation state, revision snapshots, sequential partial-failure saves, retries, and discard callbacks.
• Added the safe-area-aware fixed action and dirty-navigation dialog to the settings shell.
• Guarded Link/router/history navigation and installed native unload protection while the route is dirty.
• Targeted component/routing tests, TypeScript typecheck, and targeted ESLint pass.
