# OpenSpec Change: folder-reorg-by-domain

- **Change ID**: folder-reorg-by-domain
- **Scope**: Monorepo-wide structural change
- **Status**: PROPOSED
- **Date**: 2026-04-25

---

## Summary

Replace the runtime-tier folder split (`universal/`, `browser/`, `react/`, `api/`, `r3f/`, `server/`, `finance/`, `mcp/`, `python/`, `gaming/`) with a **domain-first** layout where every folder corresponds 1:1 to a plugin in the upcoming `suaveplan-skills` marketplace. Tier becomes a per-package property (declared via `package.json` deps, `exports`, and the `"browser"` field) rather than a directory boundary.

Concurrently:

1. Retire `@suaveplan/overview` (manifest browser library) and replace with a generated `MANIFEST.md` at the repo root.
2. Retire `FOLDERS.yml` (replaced by the new layout itself + `MANIFEST.md`'s tier-overlay view).
3. Update every `CLAUDE.md` and `openspec/AGENTS.md` path reference from `universal/<domain>/<pkg>` / `packages/<tier>/<pkg>` to `packages/<plugin>/<pkg>`.
4. Add a `monorepo-structure` capability spec codifying the rules.

Genesis currently has only ~21 packages on disk, so the migration cost is at its lowest. Every package shipped under the legacy layout is one more `git mv` later.

---

## Motivation

The tier-first layout was a quick first cut that has not held up:

- **Cross-tier domains are scattered.** `drive` lives in `universal/storage/`, `drive-webrtc` in `browser/network/`, `react-drive-sharing` in `react/platform/`, and a future `api-plugin-file-upload` would land in `api/data/` — four directories for one feature surface.
- **The same redundancy exists for booking, dmx, audio, video, geo, and almost every gaming feature** (universal core + r3f renderer + react UI + api plugin live in 3–4 folders).
- **`r3f/` is a deprecated category by `FOLDERS.yml`'s own admission** — gaming r3f packages were already relocated into `gaming/`. The remaining three (`r3f-earth`, `r3f-booking`, `r3f-dmx`) are stranded.
- **Tier signal is redundant.** Whether a package is browser-only is determined by `package.json` (`"browser"` field, browser-only deps); the directory adds nothing.
- **Plugin marketplace coupling.** The forthcoming `suaveplan-skills` marketplace ships ~50 plugins, each a vertical slice across tiers. If folders mirror plugins, generating the marketplace, scaffolding new packages, and onboarding contributors all collapse to one mental model.

## Design

### New folder layout

```text
packages/
  <plugin-name>/
    <package-name>/
      package.json
      tsconfig.json
      vitest.config.ts
      src/
      tests/
      README.md
```

Plugin names match the `suaveplan-<plugin>` keys without the `suaveplan-` prefix. Inside a plugin folder, package directory names match the package's npm name without the `@suaveplan/` prefix.

### Plugin → package assignment (51 plugins, all 356 current + 22 future packages)

## MANIFEST.md (replaces @suaveplan/overview)

A repo-root `MANIFEST.md` is generated by `scripts/generate-manifest.ts` from on-disk truth (each package's `package.json`). It provides:

1. **Plugin × package table** — every plugin folder, every package within, dependency count, coverage status, npm version.
2. **Tier-overlay view** — packages grouped by inferred tier (universal / browser / react / r3f / server / python) for the rare case someone wants the old listing. Tier is inferred from `engines`, `"browser"` field, peer deps (`react`, `@react-three/fiber`), and `bin` entries.
3. **Dependency graph** — DOT-format adjacency list embedded in a fenced code block; can be piped to Graphviz.
4. **Stale-manifest CI check** — a CI job runs `bun scripts/generate-manifest.ts --check` and fails if the committed `MANIFEST.md` differs from the regenerated output.

`@suaveplan/overview` is deleted from `packages/` (it is currently published at `0.1.0` to Verdaccio; per genesis convention pre-1.0.0 deletion is a `bun scripts/unpublish.ts --package @suaveplan/overview` operation).

---

## Migration approach

**Single bulk migration in one PR.** A long-running rename branch is the worst of both worlds; everything in `packages/` moves at once, in one mechanical commit, followed by a configuration-update commit.

1. **`scripts/migrate-folders.ts`** — reads the assignment table from this proposal (or a sibling `assignment.yml`), runs `git mv packages/<old>/<pkg>/ packages/<plugin>/<pkg>/` for every package, and updates root `package.json` `workspaces` glob (`packages/*/*` covers every plugin/package pair).
2. **Path updates in configs:**
   - `turbo.json` — no changes needed (uses workspace globs).
   - Every `vitest.config.ts` referencing `path.resolve(__dirname, '../../testing/...')` — paths are auto-correct because they're relative to each package and the new layout still has `packages/<plugin>/<pkg>/` as the same depth.
   - `tsconfig.json` `paths` mapping — regenerate.
   - Per-package `package.json` exports — unchanged (relative to package root).
3. **Doc updates:**
   - `CLAUDE.md` package list paths.
   - `openspec/AGENTS.md` — every `universal/<domain>/<pkg>` reference becomes `packages/<plugin>/<pkg>`.
   - Existing OpenSpec changes' proposals — leave historic; only update `tasks.md` for in-flight changes.
4. **Delete `FOLDERS.yml`.**
5. **Generate `MANIFEST.md`** for the first time, commit it.
6. **Add CI check** `bun scripts/generate-manifest.ts --check`.

---

## Out of scope

- **Renaming any package.** Only directories move; npm names stay identical.
- **Changing exports or APIs.** Pure structural change.
- **Migrating off Verdaccio for republish.** Republishes happen as part of normal pre-publish gates after the move.

---

## Impact

- **Every package on genesis** (~21 currently shipped + ~5 in flight) gets a `git mv`. No code change required inside packages.
- **All in-flight OpenSpec changes** that reference target paths (`enterprise-booking`, `enterprise-testing-*`, etc.) need their `Target path:` line updated. This is mechanical.
- **Existing `@suaveplan/overview` consumers** (none in genesis source — it was a leaf manifest reader) lose the package; the replacement is reading `MANIFEST.md` directly or running `scripts/generate-manifest.ts`.
- **Future `suaveplan-skills` marketplace** can be generated directly from the folder layout: each `packages/<plugin>/` becomes one plugin manifest.
