T-WDXJ-sdf-scaffold-tauri-nuxt-app

Status: closed/done · Impact: high · Complexity: large

Goal

Stand up apps/sdf — the SDF operator app decided in D-0018-sdf-control-plane-app — as a first-class monorepo citizen by replaying the proven pumice conversion recipe over template-tauri-nuxt. Unblocks every later SDF phase.

Today

Location	Role today
`apps/`	dashboard, family, polish, pumice, sdlc — no `sdf`
`Cargo.toml`	root workspace: `packages/rust/*`, family products, pumice crates/src-tauri
`.moon/tasks/tauri.yml`	inherited task surface for `tags: ['tauri']` projects
`apps/pumice/moon.yml`	the documented conversion precedent (mergeArgs, noop test aggregate, server preset)

The template lives outside the repo at /Users/sksizer/Developer/templates/template-tauri-nuxt (github sksizer/template-tauri-nuxt); scaffold from a fresh checkout of its origin/main (local clone was behind at review time).

Proposed

apps/sdf/ exists with peer src-tauri/ (Rust crate sdf, member of the root cargo workspace, workspace-pinned deps) and src-nuxt/ (Nuxt 4, Bun, own apps/sdf/bun.lock), a thin moon.yml (tags: ['tauri'], language: 'rust'), lefthook/justfile hooks rewritten pnpm→bun, a workflow_dispatch CI workflow, and all inherited moon gates green. No pnpm lockfiles anywhere under apps/sdf.

Approach

Copy template checkout into apps/sdf (drop .git, Makefile, template-fleet scripts not applicable in-monorepo); run rename.sh with PROJECT_NAME=sdf, BUNDLE_ID=com.sksizer.sdf.
Bun-ify per pumice (T-M7QX precedent): app-level workspaces (src-nuxt), delete pnpm lockfiles, bun install → apps/sdf/bun.lock, rewrite pnpm run → bun run in package.json/justfile/lefthook.yml, trustedDependencies as pumice.
moon.yml per pumice: layer: application, stack: frontend, language: rust, tags: ['tauri']; declare dev (server preset) and build; override fmt/fmt-check/lint/backend-test with --manifest-path src-tauri/Cargo.toml + mergeArgs: 'replace'.
Add apps/sdf/src-tauri to root Cargo.toml members; consume { workspace = true } pins (tauri 2); remove per-app Cargo.lock and rust-toolchain.toml in favor of workspace stable.
CI: .github/workflows/sdf-ci.yml modeled on pumice-ci.yml (ubuntu-22.04, webkit apt deps, workflow_dispatch).
Verify: moon run sdf:check, cargo check -p sdf, cd apps/sdf/src-nuxt && bun run generate, bun run tauri build --debug locally.

Files to touch

Location	Kind	Change
`apps/sdf/`	new	full app tree from template (src-tauri, src-nuxt, justfile, lefthook.yml, mise.toml, sdlc.yaml, moon.yml)
`Cargo.toml`	modify	add `apps/sdf/src-tauri` to workspace members
`.github/workflows/sdf-ci.yml`	new	workflow_dispatch CI per pumice-ci.yml

Acceptance criteria

AC-1: moon run sdf:check exits 0 (inherited tauri aspect: frontend lint/typecheck/test/format-check + rust fmt-check/lint).
AC-2: cargo check -p sdf builds under the root workspace (single root Cargo.lock; no apps/sdf/**/Cargo.lock).
AC-3: bun run generate in src-nuxt emits the static SPA to .output/public (browser mode artifact); bun run tauri build --debug produces a launchable desktop binary locally.
AC-4: no pnpm/npm lockfiles under apps/sdf; git grep -l pnpm -- apps/sdf returns only doc mentions, no executable hooks/scripts.
AC-5: moon auto-registers project id sdf (moon query projects lists it) with zero .moon/workspace.yml edits.

Out of scope

Any dashboard views or data fetching (T-6S37).
ontogen codegen pipeline (T-UBPG).
Deleting apps/dashboard (T-QT7X).
Re-enabling always-on Tauri CI (repo-wide stance, PRs #759/#763).

Dependencies

none (first code phase of M-5EEX; lands stacked on the D-0018 docs PR)

Discovery context

Phase 1 of D-0018-sdf-control-plane-app; recipe from D-0016-pumice-app-integration / T-K3PN / T-M7QX / T-X8CF as documented in apps/pumice/moon.yml comments.
