add-repositorylisted

Add a data/domain slice ONLY — model, repository interface + impl, use case, and a hand-written fake — to this Compose Multiplatform app, cloned deterministically from the `home` exemplar's data layer. No screen, no ViewModel, no nav route, no spec clauses. Use this when the user wants to "add a repository", "add a data source", "model a new entity", "new entity with a repository", or names a domain noun they want backed by data before any UI exists (e.g. "add a Tag repository", "I need a data source for Bookmarks"). Works with NO create-cmp plugin installed — the stamper (`qa/scaffold-feature.mjs --preset repository`) and this skill both ship inside the generated project.

This is the `repository` subset of `add-feature` — same stamper, same rename mechanic, filtered to just the 5 data/domain files. Use it when you want the data layer to exist before any screen consumes it (e.g. you're modeling several entities up front, or a screen for this entity will come later via `add-screen`). **Name the lane first, out loud.** Before any tool runs, tell the human in a sentence which lane this request takes (`CLAUDE.md` §"After genesis"): an entity carrying decisions worth recording (data-model semantics, boundary rules) goes through a feature brief (`docs/features/<name>.md`, signed before code); an ordinary entity is direct lane — say so, then continue here. Never route silently. ## Why a stamper and not hand-written files Every hand-written file is a drift chance in this project's architecture. `qa/scaffold-feature.mjs --preset repository` produces a **conforming skeleton by construction** for the data/domain layer: a domain model, a domain repository interface, a use
