The driver reads the existing namespace to check for `paperclip.ai/managed-by=paperclip` before mutating โ€” it will not touch namespaces it did not create. `watch` is used in M2 to track namespace deletion events. | +| `resourcequotas` | Apply `paperclip-tenant-quota` to each namespace. Must `patch` on re-provision (quota overrides from `cluster_tenant_policies`). | +| `limitranges` | Apply `paperclip-tenant-limits`. Must `patch` on billing tier changes. | +| `secrets` | (a) Create `paperclip-image-pull` (registry credentials per namespace). (b) In M2: create per-Job ephemeral Secrets that hold resolved `secret_ref` values; these carry an `OwnerReference` to the Job so Kubernetes GCs them automatically. | +| `serviceaccounts` | Create the `paperclip-agent` ServiceAccount in each namespace (`automountServiceAccountToken: false`). | +| `configmaps` | Reserved for M2: workspace-init config and adapter configuration injection via `ConfigMap` volumes. | +| `persistentvolumeclaims` | M2: create per-agent `PVC` (`agent-{agentSlug}-workspace`) for warm workspace storage. `watch` is needed to wait for the PVC to be bound before submitting the Job. | +| `pods` | M2: read pod status to determine Job phase; gate on pod `Ready` condition. | +| `pods/log` | M2: stream container logs from agent pods back to the Paperclip run log via `ctx.onLog`. | +| `pods/exec` | M2: reserved for workspace-init debug flows and operator diagnostics. Not used in M1. | + +### Batch API group (`apiGroups: ["batch"]`) + +| Resource | Why the driver needs it | +|----------|------------------------| +| `jobs` | M2: submit one `Job` per agent run. The driver needs `watch` to track the Job to completion and map terminal conditions to `AdapterExecutionResult` exit codes. `delete` is used for cancellation. | + +This rule is present in the ClusterRole now so that M2 can begin scheduling runs without an RBAC update. In M1, the driver's `run()` method returns `NOT_YET_SUPPORTED` before any Job is submitted. + +### Networking API group (`apiGroups: ["networking.k8s.io"]`) + +| Resource | Why the driver needs it | +|----------|------------------------| +| `networkpolicies` | Apply three `NetworkPolicy` objects per namespace: `default-deny-ingress`, `default-deny-egress`, `paperclip-agent-egress`. Must `patch` on re-provision to update the FQDN allowlist or control-plane selector. `watch` is not required (policies are reconciled at `ensure-tenant` time). | + +### RBAC API group (`apiGroups: ["rbac.authorization.k8s.io"]`) + +| Resource | Why the driver needs it | +|----------|------------------------| +| `roles` | Reserved for M2: in-namespace `Role` objects for fine-grained per-job access control. | +| `rolebindings` | The driver creates a `RoleBinding` named `paperclip-driver` in each tenant namespace, binding the `paperclip-tenant-manager` ClusterRole to the driver ServiceAccount scoped to that namespace. This is required for the driver to have write access to namespaced resources after initial namespace creation. | + +**Important:** The ability to create `RoleBindings` is a powerful permission. The driver is constrained to bind only the roles it already holds (the k8s API enforces that you cannot grant more than you have). The `paperclip-driver` identity should be protected: the ServiceAccount token must not be exposed outside the control plane. + +### Cilium API group (`apiGroups: ["cilium.io"]`) + +| Resource | Why the driver needs it | +|----------|------------------------| +| `ciliumnetworkpolicies` | When the cluster has the Cilium CNI, apply a `CiliumNetworkPolicy` alongside the vanilla NetworkPolicy. The CNP provides L7/FQDN egress filtering (see [security-model.md](./security-model.md#cilium-variant-fqdn-allowlist-auto-detected)).

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Deliver the foundation of the multi-tenant Kubernetes execution target โ€” types, registry, cluster-connection storage, k8s client wrapper, and idempotent tenant-namespace provisioning (Namespace + RBAC + ResourceQuota + LimitRange + NetworkPolicy + Cilium variant + image-pull-secret) โ€” verifiable end-to-end against a `kind` cluster. No agent execution yet (that's M2). No web UI yet (that's M3). The CLI command `paperclipai cluster ensure-tenant ` exists and works. + +**Architecture:** Add a `kubernetes` kind to the existing `AdapterExecutionTarget` discriminated union and introduce a platform-module-style `ExecutionTargetDriverRegistry`. The k8s driver lives in a new package `@paperclipai/execution-target-kubernetes` and is wired into the server through a thin registration shim. Three new Drizzle tables back the storage. All k8s spec building is done as **pure functions** that take a context object and return raw API objects; a separate `ensureTenantNamespace` orchestrator applies them via `@kubernetes/client-node`. Pure builders are unit-tested with golden snapshots; the orchestrator is integration-tested against `kind`. + +**Tech Stack:** TypeScript, Drizzle ORM (PostgreSQL), `@kubernetes/client-node`, `vitest`, `kind` (Kubernetes IN Docker) for integration tests, `testcontainers-node` for spinning kind in CI.

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Make a real `claude_local` agent run end-to-end inside a Kubernetes pod โ€” workspace cloned from git in an init container, claude-code CLI invoked with prompts, stdout streamed back to Paperclip, structured events posted via run-JWT auth, Job lifecycle managed (TTL cleanup, OwnerReference GC, cancellation), all observable in `kubectl logs`. + +**Architecture:** Extends M1 by replacing the driver's `run()` stub with a real Job-based execution path. One `batch/v1 Job` per heartbeat carries a paperclip-workspace-init init container that resolves the workspace strategy and an agent runtime container that runs `paperclip-agent-shim` (Go static binary) which exec's the actual adapter CLI. A per-Job ephemeral `Secret` (with `OwnerReferences` to the Job for auto-GC) carries the bootstrap token, resolved adapter env (LLM keys), and a short-TTL git credential handle. Stdout streams via `pods/log` watch; `Job` and `Pod` Events surface as `[k8s]`-prefixed log lines; structured events (`init`/`assistant`/`tool_call`/`result`) are POSTed by the agent shim to `/api/runs/:runId/events` after a single bootstrap-token-for-run-JWT exchange. PVC-per-agent persists workspaces between heartbeats. + +**Tech Stack:** TypeScript (orchestrator + server routes + adapter wiring), Go 1.22 (`paperclip-agent-shim` static binary), Node.js (`paperclip-workspace-init` script consuming `@paperclipai/workspace-strategy`), Distroless or `ubuntu-slim` base images with `tini` + `git`, `@kubernetes/client-node` v0.21, `kind` for integration tests, `cosign` keyless OIDC for image signing in CI. + +**Spec reference:** `docs/superpowers/specs/2026-05-08-paperclip-cloud-adapter-design.md` โ€” sections ยง3 (Pod Lifecycle), ยง4 (Workspace Persistence), ยง5 (Images & Secrets), ยง6 (Networking & Callback), ยง7 (Observability + Failure Modes + Testing). + +**M1 reference:** `docs/superpowers/plans/2026-05-08-paperclip-cloud-adapter-m1-plan.md` (30 commits on `feat/k8s-cloud-adapter-m1`; tenant provisioning is done โ€” namespace, RBAC, ResourceQuota, LimitRange, NetworkPolicy vanilla + Cilium variant, image pull secret, ClusterConnections service, ExecutionTargetDriverRegistry, CLI commands). + +**Branch:** `feat/k8s-cloud-adapter-m2`, branched from `feat/k8s-cloud-adapter-m1` (M1 will land first; M2 builds on top). + +--- + +## Architectural Decisions Locked Before Planning + +| # | Decision | Rationale | +|---|---|---| +| M2-1 | `paperclip-agent-shim` is a Go 1.22 static binary | Tiny program (read config โ†’ exec adapter CLI โ†’ frame stdout). Go gives ~3MB stripped binary with ~5ms startup. No Node tax for the PID-1 supervisor. | +| M2-2 | `paperclip-workspace-init` is a Node script using `@paperclipai/workspace-strategy` | Reuses the canonical TS implementation. Base image needs Node anyway (claude-code is a Node CLI), so no extra cost. Avoids reimplementing git workflow logic in Go. | +| M2-3 | Workspace strategy is extracted to `@paperclipai/workspace-strategy` | One implementation consumed by both the server local-adapter path AND the init container. Real refactor; ~3-5 days. Risk #1 resolved. | +| M2-4 | Bootstrap-token-only auth in M2; full TokenReview deferred to V2 | Same auth path the cursor-cloud adapter ships. Bootstrap token TTL = 10 min, single-use, bound to Job UID. Risk #5 resolved (with explicit V2 follow-up). | +| M2-5 | Resource defaults measured during M2 implementation; tuning in same PR | When the end-to-end test runs real claude_local heartbeats we capture p50/p95/p99 CPU/memory and adjust `LimitRange` defaults in the same commit. Risk #4 resolved. | +| M2-6 | Single adapter coverage in M2 โ€” `claude_local` only | The other six adapters (codex/gemini/opencode/acpx/pi/cursor) keep their M1 rejection branch and gain k8s execution in M3. Tightens M2 scope. | +| M2-7 | One image family member in M2 โ€” `agent-runtime-base` + `agent-runtime-claude` | M3 builds the rest. Multi-arch (amd64+arm64) shipped from day one. | +| M2-8 | No sidecars in V1 (per spec ยง3.3); log streaming via `pods/log` watch | Spec decision; M2 honors it. | + +--- + +## Scope Note + +M2 is one coherent vertical slice โ€” it produces a real, demonstrable capability ("the hired agent works on Kubernetes") that can ship and be merged. The plan is large because the slice is wide (Go binary + Node script + image build + 5 server routes + 6 orchestrator builders + driver implementation + claude_local wiring + 4 integration tests + image CI), but it's not split because the slice has no internal cut-points where partial completion would be useful โ€” without callbacks, the Job runs blindly; without orchestrator extensions, the routes have nothing to talk to; etc. + +Operators who want to try M2 mid-development can run individual integration tests, but the merge unit is the whole slice. + +--- + +## File Structure + +### New packages + +``` +packages/workspace-strategy/ # NEW +โ”œโ”€โ”€ package.json # @paperclipai/workspace-strategy +โ”œโ”€โ”€ tsconfig.json +โ””โ”€โ”€ src/ + โ”œโ”€โ”€ index.ts # public exports + โ”œโ”€โ”€ types.ts # WorkspaceStrategySpec, WorkspaceStrategyKind + โ”œโ”€โ”€ execute.ts # executeStrategy(spec, root, deps) โ€” top-level dispatch + โ”œโ”€โ”€ git-clone.ts # cold + warm git-clone strategy + โ”œโ”€โ”€ git-worktree.ts # bare clone + worktree-add strategy + โ”œโ”€โ”€ existing-path.ts # validation-time rejector for k8s;

Every existing adapter (`claude_local`, `codex_local`, `gemini_local`, `opencode_local`, `acpx_local`, `pi_local`, `hermes_local`) gains the ability to run inside a Kubernetes pod by selecting a `kubernetes` execution target โ€” no per-adapter rewrites. Tenancy is enforced via namespace-per-company with the standard k8s-native isolation primitives (RBAC, ResourceQuota, NetworkPolicy, PodSecurity Restricted, per-namespace image pull credentials, ephemeral per-Job Secrets). Each agent gets a persistent `PersistentVolumeClaim` for warm workspaces; each run is an ephemeral `Job`. The orchestrator runs as library code inside the Paperclip server using `@kubernetes/client-node` โ€” no separate operator binary, no CRDs, in V1. + +Cluster topology is hybrid by design: the same code path serves an in-cluster Paperclip (workloads in adjacent namespaces) and a cross-cluster Paperclip (control plane elsewhere; workload cluster reached via stored kubeconfig). Cross-cluster auth reuses the bootstrap-token โ†’ run-JWT exchange pattern already specified for the Cursor Cloud adapter. + +The Helm chart for the Paperclip control plane itself is **out of scope for this spec** โ€” it's tracked separately and gated to ship after the cloud adapter lands. + +--- + +## Goals + +1. Run Paperclip agents on Kubernetes with strong tenant isolation suitable for multi-tenant SaaS. +2. Keep adapters unchanged โ€” extension via the existing `executionTarget` seam, not new adapter types. +3. Single shared orchestration package; no per-adapter k8s code. +4. Match k8s-native idioms: `Job`, `PVC`, `Namespace`, `NetworkPolicy`, `ResourceQuota`, `LimitRange`, `PodSecurity` Restricted. +5. Reuse the bootstrap-token โ†’ run-JWT auth flow already shipped for the Cursor Cloud adapter โ€” one server-side route, two callers. +6. Support both same-cluster and cross-cluster topologies behind one configuration model. +7. Security baseline aligned with NSA/CISA Kubernetes Hardening and CIS Kubernetes Benchmark. +8. Operator-debuggable via standard tools: `kubectl get jobs -n paperclip-acme-corp`, audit log entries, structured run-level events. + +## Non-Goals (V1) + +- Helm chart for the Paperclip control plane (separate spec, gated to follow). +- Per-company BYO cluster (one or more cluster connections at the *instance* level only). +- Pod-per-agent mode (StatefulSet + KEDA scale-to-zero) โ€” designed-for, not built. +- External Secrets Operator integration โ€” abstraction in place, no driver in V1. +- VolumeSnapshot-based agent cloning. +- `PaperclipAgentRun` CRD + reconciliation operator โ€” not built unless reconciliation needs justify it. +- Fine-grained image attestation enforcement (we sign; we don't enforce verify in admission). +- IPv6 dual-stack pods. + +--- + +## Architectural Decisions + +| # | Decision | Rationale | +|---|---|---| +| 1 | Add a new `kubernetes` kind to the existing `AdapterExecutionTarget` rather than creating a `kubernetes_pod` adapter. | Every adapter inherits k8s execution for free. Single shared orchestrator. Matches the pattern already used for `ssh` and `sandbox`. | +| 2 | Tenant boundary = `Namespace` per Paperclip company. | K8s-native isolation primitive. RBAC, ResourceQuota, NetworkPolicy, PSS labels all attach naturally. Free, mature, widely understood. | +| 3 | Workload granularity inside a tenant = pod-per-run as a `Job`, with PVC-per-agent for warm workspaces. | Strict isolation per run; PVC reuse keeps workspaces warm without coupling pod lifetimes. Pod-per-company was rejected (poor isolation, doesn't actually save cluster cost). | +| 4 | Hybrid topology with bootstrap-token auth. | One auth path serves SaaS (Paperclip on control-plane cluster, agents on workload cluster) and self-hosted single-cluster. Reuses cursor-cloud's exchange route. | +| 5 | Imperative orchestration via `@kubernetes/client-node` from the Paperclip server. No CRDs, no operator binary. | Smallest moving parts. Reconciliation is delegated to k8s primitives (Job `backoffLimit`, `TTLAfterFinished`, `OwnerReferences`, `PodFailurePolicy`). Easy to test against `kind`. | +| 6 | Workspace bootstrap = init container running the existing Paperclip workspace strategy. | Reuses existing strategy logic; agents see identical filesystem layout to local. Cold = full clone, warm = fetch+reset. | +| 7 | Namespace naming = `paperclip-{companySlug}` (operator-friendly), with `-{shortHash}` fallback on collision or DNS-1123 overflow. | Slug already exists in Paperclip (URL `:companyPrefix`). `kubectl` users get human-readable names. Immutable `paperclip.ai/company-id` label is the canonical machine identifier. | +| 8 | The platform-module surface is extended (in spec, not yet existing) with `registerExecutionTargetDriver()` to keep parity with `registerAgentAdapter()` / `registerStorageProvider()`. The k8s driver is the first registered driver. | Keeps the door open for third-party drivers (Nomad, ECS, Modal-style) without core changes later. Honors the user's "leverage the plugin system" intent within the actual extension model. | + +--- + +## 1.
