 - Split `apps/front` into a thin entrypoint, shared `src/core/utils.ts`, and a dedicated `src/domains/links/{router,service}.ts` flow
 - Moved link resolve/prepare logic and orchestrator calling into the links domain service so `src/index.ts` only wires middleware and routes
 - Verified the cleaned `apps/front` app compiles cleanly with `tsc --noEmit`

+### 21 — Frontend Remote Function Migration
+
+- Migrated the legacy front server-side link flow into `apps/frontend` as SvelteKit remote functions in `src/lib/domains/link/link.remote.ts`
+- Added frontend request flow IDs in `src/hooks.server.ts` so remote functions build `FlowExecCtx` from `event.locals` consistently
+- Preserved the two server operations as a query/command split: link resolve remains read-only and session prepare remains the mutating flow that calls orchestrator
+
+### 22 — Frontend Link Domain Refactor
+
+- Reduced `apps/frontend/src/lib/domains/link/link.remote.ts` to thin remote-function entrypoints only
+- Split link-domain server responsibilities into dedicated files: `link.data.ts`, `link.utils.ts`, `orchestrator.service.ts`, and `link.service.ts`
+- Moved orchestrator calling, link validation shaping, and reusable error creation out of the remote layer for a cleaner domain boundary
