 This tracker is **not** a claim that every listed repo is still on `npm` today. Some repos may already use `pnpm` in part or in full; those repos should be handled here only if they still require migration cleanup, downstream validation, or tracker-hosting updates.
 
+This migration is a **repo-by-repo standardization effort across independent repositories**. It is **not** a plan to merge product repos into a single mega-monorepo. `learning_ai_common_plat` remains the canonical `pnpm` workspace for shared packages/services, while product repos stay independently versioned and independently deployable.

+## Follow-up Validation: Local Gitea npm Registry Rehearsal
+
+This tracker remains complete for the pnpm migration itself.
+
+However, a new post-migration validation stream is now in progress:
+
+- replacing tarball-based `@bytelyst/*` Docker consumption with the local Gitea npm registry
+- validating the full flow on this Mac before any Azure rollout
+- using `learning_ai_flowmonk` as the first registry-migration pilot
+
+Current status:
+
+- host-side local Gitea registry publishing is validated
+- host-side local consumer installs are validated
+- FlowMonk host-side install, typecheck, and tests against the local Gitea registry are validated
+- Docker-side validation remains blocked by the local Homebrew Gitea ↔ Docker build networking and tarball URL generation path
