# B2 — Fresh-install skills sync path

## Problem

Greenfield wizard on `next` reported:

```text
Skills sync script not found at ~/.config/mosaic/bin/mosaic-sync-skills
Skills: install failed
```

## Diagnosis

The framework install migration removed the legacy `~/.config/mosaic/bin/` directory and now installs framework helper scripts under:

```text
~/.config/mosaic/tools/_scripts/
```

`packages/mosaic/src/stages/finalize.ts` still resolved wizard helper scripts from `mosaicHome/bin`, so wizard-selected skills failed even though `mosaic-sync-skills` was present in the current framework layout.

## Fix

- Resolve framework helper scripts through `tools/_scripts/<name>` first.
- Keep a legacy `bin/<name>` fallback for pre-migration installs.
- Point missing-script warnings at the current `tools/_scripts` layout.
- Update the finalize skills test fixture to model the fresh framework layout.
- Update framework README examples from legacy `bin/` helper paths to `tools/_scripts/`.

## Verification

- Unit: `pnpm --filter @mosaicstack/mosaic test -- finalize-skills`
- Gates: `pnpm typecheck`, `pnpm lint`, `pnpm format:check`, `pnpm build`
- Fresh path: ran `packages/mosaic/framework/install.sh` with a temp `MOSAIC_HOME` and `MOSAIC_SYNC_ONLY=1`; verified `tools/_scripts/mosaic-sync-skills` exists, legacy `bin/mosaic-sync-skills` does not, and the script installs a selected fake `lint` skill into Mosaic + Pi runtime skill directories.
