Plan 4: SaaS Cleanup — Strip to Vendor Management Plane

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Remove all migrated code from the SaaS layer (environments, apps, deployments, ClickHouse access) and strip it down to a thin vendor management plane: tenant lifecycle, license generation, billing, and Logto organization management.

Architecture: The SaaS retains only vendor-level concerns. All runtime management, observability, and user management is now in the server. The SaaS communicates with server instances exclusively via REST API (ServerApiClient). ClickHouse dependency is removed entirely.

Tech Stack: Java 21, Spring Boot 3.4.3, PostgreSQL 16

Repo: C:\Users\Hendrik\Documents\projects\cameleer-saas

Prerequisite: Plans 1-3 must be implemented in cameleer-server first.

Flyway Migrations to KEEP

The existing migrations (V001-V009) can remain since they're already applied. Add a new cleanup migration:

src/main/resources/db/migration/V010__drop_migrated_tables.sql

---

Task 1: Remove ClickHouse Dependency

• Step 1: Delete ClickHouse files

rm -rf src/main/java/net/siegeln/cameleer/saas/log/ClickHouseConfig.java
rm -rf src/main/java/net/siegeln/cameleer/saas/log/ClickHouseProperties.java
rm -rf src/main/java/net/siegeln/cameleer/saas/log/ContainerLogService.java
rm -rf src/main/java/net/siegeln/cameleer/saas/log/LogController.java
rm -rf src/main/java/net/siegeln/cameleer/saas/log/dto/

• Step 2: Remove ClickHouse from AgentStatusService

Delete AgentStatusService.java and AgentStatusController.java entirely (agent status is now a server concern).

rm -rf src/main/java/net/siegeln/cameleer/saas/observability/

• Step 3: Remove ClickHouse config from application.yml

Remove the entire cameleer.clickhouse: section.

• Step 4: Remove ClickHouse JDBC dependency from pom.xml

Remove:

<dependency>
    <groupId>com.clickhouse</groupId>
    <artifactId>clickhouse-jdbc</artifactId>
</dependency>

• Step 5: Verify build

Run: cd /c/Users/Hendrik/Documents/projects/cameleer-saas && mvn compile Expected: BUILD SUCCESS. Fix any remaining import errors.

• Step 6: Commit

git add -A
git commit -m "feat: remove all ClickHouse dependencies from SaaS layer"

---

Task 2: Remove Environment/App/Deployment Code

• Step 1: Delete environment package

rm -rf src/main/java/net/siegeln/cameleer/saas/environment/

• Step 2: Delete app package

rm -rf src/main/java/net/siegeln/cameleer/saas/app/

• Step 3: Delete deployment package

rm -rf src/main/java/net/siegeln/cameleer/saas/deployment/

• Step 4: Delete runtime package

rm -rf src/main/java/net/siegeln/cameleer/saas/runtime/

• Step 5: Remove AsyncConfig deploymentExecutor bean

In AsyncConfig.java, remove the deploymentExecutor bean (or delete AsyncConfig if it only had that bean).

• Step 6: Update TenantService

Remove any calls to EnvironmentService.createDefaultForTenant() from TenantService.java. The server now handles default environment creation.

• Step 7: Remove runtime config from application.yml

Remove the entire cameleer.runtime: section.

• Step 8: Verify build

Run: cd /c/Users/Hendrik/Documents/projects/cameleer-saas && mvn compile Expected: BUILD SUCCESS. Fix any remaining import errors.

• Step 9: Commit

git add -A
git commit -m "feat: remove migrated environment/app/deployment/runtime code from SaaS"

---

Task 3: Database Cleanup Migration

• Step 1: Create cleanup migration

-- V010__drop_migrated_tables.sql
-- Drop tables that have been migrated to cameleer-server

DROP TABLE IF EXISTS deployments CASCADE;
DROP TABLE IF EXISTS apps CASCADE;
DROP TABLE IF EXISTS environments CASCADE;
DROP TABLE IF EXISTS api_keys CASCADE;

• Step 2: Commit

git add src/main/resources/db/migration/V010__drop_migrated_tables.sql
git commit -m "feat: drop migrated tables from SaaS database"

---

Task 4: Remove Docker Socket Dependency

• Step 1: Update docker-compose.yml

Remove from cameleer-saas service:

volumes:
  - /var/run/docker.sock:/var/run/docker.sock
  - jardata:/data/jars
group_add:
  - "0"

The Docker socket mount now belongs to the cameleer-server service instead.

• Step 2: Remove docker-java dependency from pom.xml

Remove:

<dependency>
    <groupId>com.github.docker-java</groupId>
    <artifactId>docker-java-core</artifactId>
</dependency>
<dependency>
    <groupId>com.github.docker-java</groupId>
    <artifactId>docker-java-transport-zerodep</artifactId>
</dependency>

• Step 3: Commit

git add docker-compose.yml pom.xml
git commit -m "feat: remove Docker socket dependency from SaaS layer"

---

Task 5: Update SaaS UI

• Step 1: Remove environment/app/deployment pages from SaaS frontend

Remove pages that now live in the server UI:

• EnvironmentsPage
• EnvironmentDetailPage
• AppDetailPage

The SaaS UI retains:

• DashboardPage — vendor overview (tenant list, status)

• AdminTenantsPage — tenant management

• LicensePage — license management

• Step 2: Update navigation

Remove links to environments/apps/deployments. The SaaS UI should link to the tenant's server instance for those features (e.g., "Open Dashboard" link to https://{tenant-slug}.cameleer.example.com/server/).

• Step 3: Commit

git add ui/
git commit -m "feat: strip SaaS UI to vendor management dashboard"

---

Task 6: Expand ServerApiClient

• Step 1: Add provisioning-related API calls

The ServerApiClient should gain methods for tenant provisioning:

public void pushLicense(String serverEndpoint, String licenseToken) {
    post(serverEndpoint + "/api/v1/admin/license")
            .body(Map.of("token", licenseToken))
            .retrieve()
            .toBodilessEntity();
}

public Map<String, Object> getHealth(String serverEndpoint) {
    return get(serverEndpoint + "/api/v1/health")
            .retrieve()
            .body(Map.class);
}

• Step 2: Commit

git add src/main/java/net/siegeln/cameleer/saas/identity/ServerApiClient.java
git commit -m "feat: expand ServerApiClient with license push and health check methods"

---

Task 7: Write SAAS-INTEGRATION.md

• Step 1: Create integration contract document

Create docs/SAAS-INTEGRATION.md in the cameleer-server repo documenting:

• Which server API endpoints the SaaS calls

• Required auth (M2M token with server:admin scope)

• License injection mechanism (POST /api/v1/admin/license)

• Health check endpoint (GET /api/v1/health)

• What the server exposes vs what the SaaS must never access directly

• Env vars the SaaS sets when provisioning a server instance

• Step 2: Commit

cd /c/Users/Hendrik/Documents/projects/cameleer-server
git add docs/SAAS-INTEGRATION.md
git commit -m "docs: add SaaS integration contract documentation"

---

Task 8: Final Verification

• Step 1: Build SaaS

Run: cd /c/Users/Hendrik/Documents/projects/cameleer-saas && mvn clean verify Expected: BUILD SUCCESS with reduced dependency footprint.

• Step 2: Verify SaaS starts without ClickHouse

The SaaS should start with only PostgreSQL (and Logto). No ClickHouse required.

• Step 3: Verify remaining code footprint

The SaaS source should now contain approximately:

• tenant/ — ~4 files
• license/ — ~5 files
• identity/ — ~3 files (LogtoConfig, ServerApiClient, M2M token)
• config/ — ~3 files (SecurityConfig, SpaController, TLS)
• audit/ — ~3 files
• ui/ — stripped dashboard

Total: ~20 Java files (down from ~75).

• Step 4: Final commit

git add -A
git commit -m "chore: finalize SaaS cleanup — vendor management plane only"
