Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Replace the stub in `internal/widgetpack/install.go` with the full C10 §15.4 install flow — OCI pull, cosign keyless verification, tarball extraction, manifest validation, bundle hashing, class-collision check, atomic commit, and event emission — exposed via a new `WidgetPackService` Connect-RPC, an HTTP bundle handler at `/widgets/*`, and the existing `switchyard widget {install,list,uninstall}` CLI scaffolding. + +**Architecture:** A rewritten `widgetpack` package owns OCI fetch (`oras-go/v2`), cosign keyless verification (`sigstore-go` against the default Sigstore TUF trust root, test root injectable), Pkl-evaluator-driven manifest validation, on-disk staging with atomic rename to `/widgets///`, and an `http.Handler` that serves bundles with immutable cache headers. A new Connect-RPC `WidgetPackService { Install, List, Uninstall, Watch }` wraps the package.

Anything else → `405`. +- `If-None-Match` matching `ETag` → `304`. +- **No auth** on `/widgets/*`. Justification: the bundle is install-time-signature-verified, name+version-immutable static content; the browser's dynamic `import()` only speaks plain HTTP; the `?h=` cache-key URL is the entire reason for the design; CSP `script-src 'self'` requires same-origin static URLs; the security boundary is install-time, not per-request. + +The handler is mounted by `internal/api/listener/listener.go` outside the `/api` tree (the listener mux already discriminates static asset paths from RPC paths). + +## 9.
