fork: add CLAUDE.md describing fork model and don'ts

Captures branch model (master/dev/local), the 3-file fork delta, upstream
sync procedure, and the post-reset rule against re-introducing fork code.

+# Paperclip fork — farhoodlabs
+
+This is a thin fork of [paperclipai/paperclip](https://github.com/paperclipai/paperclip).
+Fork repo: https://git.farh.net/farhoodlabs/paperclip
+
+## Branch model
+
+| Branch | Purpose |
+|---|---|
+| `master` | Pure mirror of `upstream/master`. No fork files. Sync via `git push origin upstream/master:master --force-with-lease`. |
+| `dev` | `master` + one fork commit (Dockerfile prod stage + 2 build workflows). Builds `git.farh.net/farhoodlabs/paperclip-dev:*` on push. |
+| `local` | **Deployed branch.** Same content as `dev`. Builds `git.farh.net/farhoodlabs/paperclip:*` on push. |
+
+The fork tree differs from upstream by exactly **3 files**:
+
+```
+Dockerfile                                 (production stage adds kubectl, kubeseal, uv, forgejo CLIs, tea, mmx-cli, nano, vim)
+.github/workflows/build-prod.yml           (pushes to git.farh.net/farhoodlabs/paperclip)
+.github/workflows/build-dev.yml            (pushes to git.farh.net/farhoodlabs/paperclip-dev)
+```
+
+The base/deps/build stages of the Dockerfile match upstream verbatim so upstream changes apply cleanly.
+
+## Sync upstream
+
+```bash
+git fetch upstream
+git push origin upstream/master:master --force-with-lease
+git checkout dev && git merge master && git push origin dev
+git checkout local && git merge dev && git push origin local
+```
+
+Conflicts should only ever appear on `Dockerfile` itself (if upstream changes the production stage). Resolution rule: keep upstream's deps/base/build stages exactly; preserve the fork's `RUN` block in the production stage.
+
+## Deployment
+
+Production runs in Kubernetes (`paperclip` namespace, single replica). Image: `git.farh.net/farhoodlabs/paperclip:<tag>`. Flux does not watch moving tags — rolling a fix means either pushing a semver-tagged release or `kubectl rollout restart deploy/paperclip -n paperclip`.
+
+## Don't
+
+- **Don't add fork code changes.** This fork is intentionally minimal after the 2026-05-31 reset (event-loop starvation bug from accumulated drift). If a feature is missing relative to a prior fork iteration (Gitea-hosted skills, PAT support for private skill repos, secret export/import, k8s sandbox-provider plugin, agentId threading), surface the regression — don't pull it back from `git log` without explicit go-ahead.
+- **Don't commit to `local` without going through `dev` first** (and through `master` for upstream syncs). The promotion order is enforced.
+- **Don't recreate `.farhoodlabs/` overlay or `assemble-local.yml`.** That model was retired.
