+## Write small P-R
+
+Aim for the smallest piece of work that is mergeable.
+
+Mergeable means that :
+
+- it does not break the build
+- it moves the codebase one step forward
+
+P-Rs can be many things, they do not have to be complete features.
+
+### What a P-R **should** be
+
+- Introduce a new trait : This will be the place to discuss the new trait addition, its design and implementation
+- A new implementation of a trait : a new concrete implementation of the LoadBalancer trait
+- A new CI check : something that improves quality, robustness, ci performance
+- Documentation improvements
+- Refactoring
+- Bugfix
+
+### What a P-R **should not** be
+
+- Large. Anything over 200 lines (excluding generated lines) should have a very good reason to be this large.
+- A mix of refactoring, bug fixes and new features.
+- Introducing multiple new features or ideas at once.
+- Multiple new implementations of a trait/functionnality at once
+
+The general idea is to keep P-Rs small and single purpose.

+## Supporting a new field in OPNSense `config.xml`
+
+Two steps:
+- Supporting the field in `opnsense-config-xml`
+- Enabling Harmony to control the field
+
+We'll use the `filename` field in the `dhcpcd` section of the file as an example.
+
+### Supporting the field
+
+As type checking if enforced, every field from `config.xml` must be known by the code. Each subsection of `config.xml` has its `.rs` file. For the `dhcpcd` section, we'll modify `opnsense-config-xml/src/data/dhcpd.rs`.
+
+When a new field appears in the xml file, an error like this will be thrown and Harmony will panic :
+```
+     Running `/home/stremblay/nt/dir/harmony/target/debug/example-nanodc`
+Found unauthorized element filename
+thread 'main' panicked at opnsense-config-xml/src/data/opnsense.rs:54:14:
+OPNSense received invalid string, should be full XML: ()
 
-```sh
-RUST_LOG=info cargo watch --ignore-nothing -w harmony -w private_repos/ -x 'run --bin nationtech' 
 ```
 
-This will run the nationtech bin (likely `private_repos/nationtech/src/main.rs`) on any change in the harmony or private_repos folders.
+Define the missing field (`filename`) in the `DhcpInterface` struct of `opnsense-config-xml/src/data/dhcpd.rs`:
+```
+pub struct DhcpInterface {
+    ...
+    pub filename: Option<String>,
+```
+
+Harmony should now be fixed, build and run.
+
+### Controlling the field
+
+Define the `xml field setter` in `opnsense-config/src/modules/dhcpd.rs`.
+```
+impl<'a> DhcpConfig<'a> {
+    ...
+    pub fn set_filename(&mut self, filename: &str) {
+        self.enable_netboot();
+        self.get_lan_dhcpd().filename = Some(filename.to_string());
+    }
+    ...
+```
+
+Define the `value setter` in the `DhcpServer trait`  in `domain/topology/network.rs`
+```
+#[async_trait]
+pub trait DhcpServer: Send + Sync {
+    ...
+    async fn set_filename(&self, filename: &str) -> Result<(), ExecutorError>;
+    ...
+```
+
+Implement the `value setter` in each `DhcpServer` implementation.
+`infra/opnsense/dhcp.rs`:
+```
+#[async_trait]
+impl DhcpServer for OPNSenseFirewall {
+    ...
+    async fn set_filename(&self, filename: &str) -> Result<(), ExecutorError> {
+        {
+            let mut writable_opnsense = self.opnsense_config.write().await;
+            writable_opnsense.dhcp().set_filename(filename);
+            debug!("OPNsense dhcp server set filename {filename}");
+        }
+
+        Ok(())
+    }
+    ...
+```
+
+`domain/topology/ha_cluster.rs`
+```
+#[async_trait]
+impl DhcpServer for DummyInfra {
+    ...
+    async fn set_filename(&self, _filename: &str) -> Result<(), ExecutorError> {
+        unimplemented!("{}", UNIMPLEMENTED_DUMMY_INFRA)
+    }
+    ...
+```
+
+Add the new field to the DhcpScore in `modules/dhcp.rs`
+```
+pub struct DhcpScore {
+    ...
+    pub filename: Option<String>,
+```
+
+Define it in its implementation in `modules/okd/dhcp.rs`
+```
+impl OKDDhcpScore {
+        ...
+        Self {
+            dhcp_score: DhcpScore {
+                ...
+                filename: Some("undionly.kpxe".to_string()),
+```
+
+Define it in its implementation in `modules/okd/bootstrap_dhcp.rs`
+```
+impl OKDDhcpScore {
+        ...
+        Self {
+            dhcp_score: DhcpScore::new(
+                ...
+                Some("undionly.kpxe".to_string()),
+```
+
+Update the interpret (function called by the `execute` fn of the interpret) so it now updates the `filename` field value in `modules/dhcp.rs`
+```
+impl DhcpInterpret {
+        ...
+        let filename_outcome = match &self.score.filename {
+            Some(filename) => {
+                let dhcp_server = Arc::new(topology.dhcp_server.clone());
+                dhcp_server.set_filename(&filename).await?;
+                Outcome::new(
+                    InterpretStatus::SUCCESS,
+                    format!("Dhcp Interpret Set filename to {filename}"),
+                )
+            }
+            None => Outcome::noop(),
+        };

+            && boot_filename_outcome.status == InterpretStatus::NOOP
+            && filename_outcome.status == InterpretStatus::NOOP

+## Architecture Decision Record: Data Representation and UI Rendering for Score Types
+
+**Status:** Proposed
+
+**TL;DR:** `Score` types will be serialized (using `serde`) for presentation in UIs. This decouples data definition from presentation, improving scalability and reducing complexity for developers defining `Score` types. New UI types only need to handle existing field types, and new `Score` types don’t require UI changes as long as they use existing field types.  Adding a new field type *does* require updates to all UIs.
+
+**Key benefits:** Scalability, reduced complexity for `Score` authors, decoupling of data and presentation.
+
+**Key trade-off:** Adding new field types requires updating all UIs.
+
+---
+
+**Context:**
+
+Harmony is a pure Rust infrastructure orchestrator focused on compile-time safety and providing a developer-friendly, Ansible-module-like experience for defining infrastructure configurations via "Scores". These Scores (e.g., `LAMPScore`) are Rust structs composed of specific, strongly-typed fields (e.g., `VersionField`, `UrlField`, `PathField`) which are validated at compile-time using macros (`Version!`, `Url!`, etc.).
+
+A key requirement is displaying the configuration defined in these Scores across various user interfaces (Web UI, TUI, potentially Mobile UI, etc.) in a consistent and type-safe manner. As the number of Score types is expected to grow significantly (hundreds or thousands), we need a scalable approach for rendering their data that avoids tightly coupling Score definitions to specific UI implementations.
+
+The primary challenge is preventing the need for every `Score` struct author to implement multiple display traits (e.g., `Display`, `WebDisplay`, `TuiDisplay`) for every potential UI target. This would create an N x M complexity problem (N Scores * M UI types) and place an unreasonable burden on Score developers, hindering scalability and maintainability.
+
+**Decision:**
+
+1.  **Mandatory Serialization:** All `Score` structs *must* implement `serde::Serialize` and `serde::Deserialize`. They *will not* be required to implement `std::fmt::Display` or any custom UI-specific display traits (e.g., `WebDisplay`, `TuiDisplay`).
+2.  **Field-Level Rendering:** Responsibility for rendering data will reside within the UI components. Each UI (Web, TUI, etc.) will implement logic to display *individual field types* (e.g., `UrlField`, `VersionField`, `IpAddressField`, `SecretField`).
+3.  **Data Access via Serialization:** UIs will primarily interact with `Score` data through its serialized representation (e.g., JSON obtained via `serde_json`). This provides a standardized interface for UIs to consume the data structure agnostic of the specific `Score` type. Alternatively, UIs *could* potentially use reflection or specific visitor patterns on the `Score` struct itself, but serialization is the preferred decoupling mechanism.
+
+**Rationale:**
+
+1.  **Decoupling Data from Presentation:** This decision cleanly separates the data definition (`Score` structs and their fields) from the presentation logic (UI rendering). `Score` authors can focus solely on defining the data and its structure, while UI developers focus on how to best present known data *types*.
+2.  **Scalability:** This approach scales significantly better than requiring display trait implementations on Scores:
+    *   Adding a *new Score type* requires *no changes* to existing UI code, provided it uses existing field types.
+    *   Adding a *new UI type* requires implementing rendering logic only for the defined set of *field types*, not for every individual `Score` type. This reduces the N x M complexity to N + M complexity (approximately).
+3.  **Simplicity for Score Authors:** Requiring only `serde::Serialize + Deserialize` (which can often be derived automatically with `#[derive(Serialize, Deserialize)]`) is a much lower burden than implementing custom rendering logic for multiple, potentially unknown, UI targets.
+4.  **Leverages Rust Ecosystem Standards:** `serde` is the de facto standard for serialization and deserialization in Rust. Relying on it aligns with common Rust practices and benefits from its robustness, performance, and extensive tooling.
+5.  **Consistency for UIs:** Serialization provides a consistent, structured format (like JSON) for UIs to consume data, regardless of the underlying `Score` struct's complexity or composition.
+6.  **Flexibility for UI Implementation:** UIs can choose the best way to render each field type based on their capabilities (e.g., a `UrlField` might be a clickable link in a Web UI, plain text in a TUI; a `SecretField` might be masked).
+
+**Consequences:**
+
+**Positive:**
+
+*   Greatly improved scalability for adding new Score types and UI targets.
+*   Strong separation of concerns between data definition and presentation.
+*   Reduced implementation burden and complexity for Score authors.
+*   Consistent mechanism for UIs to access and interpret Score data.
+*   Aligns well with the Hexagonal Architecture (ADR-002) by treating UIs as adapters interacting with the application core via a defined port (the serialized data contract).
+
+**Negative:**
+
+*   Adding a *new field type* (e.g., `EmailField`) requires updates to *all* existing UI implementations to support rendering it.
+*   UI components become dependent on the set of defined field types and need comprehensive logic to handle each one appropriately.
+*   Potential minor overhead of serialization/deserialization compared to direct function calls (though likely negligible for UI purposes).
+*   Requires careful design and management of the standard library of field types.
+
+**Alternatives Considered:**
+
+1.  **`Score` Implements `std::fmt::Display`:**
+    *   _Rejected:_ Too simplistic. Only suitable for basic text rendering, doesn't cater to structured UIs (Web, etc.), and doesn't allow type-specific rendering logic (e.g., masking secrets). Doesn't scale to multiple UI formats.
+2.  **`Score` Implements Multiple Custom Display Traits (`WebDisplay`, `TuiDisplay`, etc.):**
+    *   _Rejected:_ Leads directly to the N x M complexity problem. Tightly couples Score definitions to specific UI implementations. Places an excessive burden on Score authors, hindering adoption and scalability.
+3.  **Generic Display Trait with Context (`Score` implements `DisplayWithContext<UIContext>`):**
+    *   _Rejected:_ More flexible than multiple traits, but still requires Score authors to implement potentially complex rendering logic within the `Score` definition itself. The `Score` would still need awareness of different UI contexts, leading to undesirable coupling. Managing context types adds complexity.

+# Architecture Decision Record: Helm and Kustomize Handling
+
+Initial Author: Taha Hawa
+
+Initial Date: 2025-04-15
+
+Last Updated Date: 2025-04-15
+
+## Status
+
+Proposed
+
+## Context
+
+We need to find a way to handle Helm charts and deploy them to a Kubernetes cluster. Helm has a lot of extra functionality that we may or may not need. Kustomize handles Helm charts by inflating them and applying them as vanilla Kubernetes yaml. How should Harmony handle it?
+
+## Decision
+
+In order to move quickly and efficiently, Harmony should handle Helm charts similarly to how Kustomize does: invoke Helm to inflate/render the charts with the needed inputs, and deploy the rendered artifacts to Kubernetes as if it were vanilla manifests.
+
+## Rationale
+
+A lot of Helm's features aren't strictly necessary and would add unneeded overhead. This is likely the fastest way to go from zero to deployed. Other tools (e.g. Kustomize) already do this. Kustomize has tooling for patching and modifying k8s manifests before deploying, and Harmony should have that power too, even if it's not what Helm typically intends.
+
+Perhaps in future also have a Kustomize resource in Harmony? Which could handle Helm charts for Harmony as well/instead.
+
+## Consequences
+
+**Pros**:
+
+- Much easier (and faster) than implementing all of Helm's featureset
+- Can potentially re-use code from K8sResource already present in Harmony
+- Harmony retains more control over how the deployment goes after rendering (i.e. can act like Kustomize, or leverage Kustomize itself to modify deployments after rendering/inflation)
+- Reduce (unstable) surface of dealing with Helm binary
+
+**Cons**:
+
+- Lose some Helm functionality
+- Potentially lose some compatibility with Helm
+
+## Alternatives considered
+
+- ### Implement Helm resouce/client fully in Harmony
+  - **Pros**:
+    - Retain full compatibility with Helm as a tool
+    - Retain full functionality of Helm
+  - **Cons**:
+    - Longer dev time
+    - More complex integration
+    - Dealing with larger (unstable) surface of Helm as a binary
+- ### Leverage Kustomize to deal with Helm charts
+  - **Pros**:
+    - Already has a good, minimal inflation solution built
+    - Powerful post-processing/patching
+    - Can integrate with `kubectl`
+  - **Cons**:
+    - Unstable binary tool/surface to deal with
+    - Still requires Helm to be installed as well as Kustomize
+    - Not all Helm features supported

+# Architecture Decision Record: Monitoring and Alerting
+
+Initial Author : Willem Rolleman
+Date : April 28 2025
+
+## Status
+
+Proposed
+
+## Context
+
+A harmony user should be able to initialize a monitoring stack easily, either at the first run of Harmony, or that integrates with existing proects and infra without creating multiple instances of the monitoring stack or overwriting existing alerts/configurations.The user also needs a simple way to configure the stack so that it watches the projects. There should be reasonable defaults configured that are easily customizable for each project    
+
+## Decision
+
+Create MonitoringStack score that creates a maestro to launch the monitoring stack or not if it is already present. 
+The MonitoringStack score can be passed to the maestro in the vec! scores list
+
+## Rationale
+
+Having the score launch a maestro will allow the user to easily create a new monitoring stack and keeps composants grouped together. The MonitoringScore can handle all the logic for adding alerts, ensuring that the stack is running etc. 
+
+## Alerternatives considered
+
+- ### Implement alerting and monitoring stack using existing HelmScore for each project
+    - **Pros**:
+        - Each project can choose to use the monitoring and alerting stack that they choose
+        - Less overhead in terms of care harmony code
+        - can add Box::new(grafana::grafanascore(namespace)) 
+    - **Cons**:
+        - No default solution implemented
+        - Dev needs to chose what they use
+        - Increases complexity of score projects
+        - Each project will create a new monitoring and alerting instance rather than joining the existing one
+
+
+- ### Use OKD grafana and prometheus
+    - **Pros**:
+        - Minimal config to do in Harmony
+    - **Cons**:
+        - relies on OKD so will not working for local testing via k3d
+
+- ### Create a monitoring and alerting crate similar to harmony tui
+    - **Pros**:
+        - Creates a default solution that can be implemented once by harmony
+        - can create a join function that will allow a project to connect to the existing solution
+        - eliminates risk of creating multiple instances of grafana or prometheus
+    - **Cons**:
+        - more complex than using a helm score
+        - management of values files for individual functions becomes more complicated, ie how do you create alerts for one project via helm install that doesnt overwrite the other alerts 
+
+- ### Add monitoring to Maestro struct so whether the monitoring stack is used must be defined 
+    - **Pros**:
+        - less for the user to define
+        - may be easier to set defaults 
+    - **Cons**:
+        - feels counterintuitive 
+        - would need to modify the structure of the maestro and how it operates which seems like a bad idea
+        - unclear how to allow user to pass custom values/configs to the monitoring stack for subsequent projects
+
+- ### Create MonitoringStack score to add to scores vec! which loads a maestro to install stack if not ready or add custom endpoints/alerts to existing stack
+    - **Pros**:
+        - Maestro already accepts a list of scores to initialize
+        - leaving out the monitoring score simply means the user does not want monitoring
+        - if the monitoring stack is already created, the MonitoringStack score doesn't necessarily need to be added to each project
+        - composants of the monitoring stack are bundled together and can be expaned or modified from the same place
+    - **Cons**:
+        - maybe need to create

+# Architecture Decision Record: Multi-Tenancy Strategy for Harmony Managed Clusters
+
+Initial Author: Jean-Gabriel Gill-Couture
+
+Initial Date: 2025-05-26
+
+## Status
+
+Proposed
+
+## Context
+
+Harmony manages production OKD/Kubernetes clusters that serve multiple clients with varying trust levels and operational requirements. We need a multi-tenancy strategy that provides:
+
+1. **Strong isolation** between client workloads while maintaining operational simplicity
+2. **Controlled API access** allowing clients self-service capabilities within defined boundaries
+3. **Security-first approach** protecting both the cluster infrastructure and tenant data
+4. **Harmony-native implementation** using our Score/Interpret pattern for automated tenant provisioning
+5. **Scalable management** supporting both small trusted clients and larger enterprise customers
+
+The official Kubernetes multi-tenancy documentation identifies two primary models: namespace-based isolation and virtual control planes per tenant. Given Harmony's focus on operational simplicity, provider-agnostic abstractions (ADR-003), and hexagonal architecture (ADR-002), we must choose an approach that balances security, usability, and maintainability.
+
+Our clients represent a hybrid tenancy model:
+- **Customer multi-tenancy**: Each client operates independently with no cross-tenant trust
+- **Team multi-tenancy**: Individual clients may have multiple team members requiring coordinated access
+- **API access requirement**: Unlike pure SaaS scenarios, clients need controlled Kubernetes API access for self-service operations
+
+The official kubernetes documentation on multi tenancy heavily inspired this ADR : https://kubernetes.io/docs/concepts/security/multi-tenancy/
+
+## Decision
+
+Implement **namespace-based multi-tenancy** with the following architecture:
+
+### 1. Network Security Model
+- **Private cluster access**: Kubernetes API and OpenShift console accessible only via WireGuard VPN
+- **No public exposure**: Control plane endpoints remain internal to prevent unauthorized access attempts
+- **VPN-based authentication**: Initial access control through WireGuard client certificates
+
+### 2. Tenant Isolation Strategy
+- **Dedicated namespace per tenant**: Each client receives an isolated namespace with access limited only to the required resources and operations
+- **Complete network isolation**: NetworkPolicies prevent cross-namespace communication while allowing full egress to public internet
+- **Resource governance**: ResourceQuotas and LimitRanges enforce CPU, memory, and storage consumption limits
+- **Storage access control**: Clients can create PersistentVolumeClaims but cannot directly manipulate PersistentVolumes or access other tenants' storage
+
+### 3. Access Control Framework
+- **Principle of Least Privilege**: RBAC grants only necessary permissions within tenant namespace scope
+- **Namespace-scoped**: Clients can create/modify/delete resources within their namespace
+- **Cluster-level restrictions**: No access to cluster-wide resources, other namespaces, or sensitive cluster operations
+- **Whitelisted operations**: Controlled self-service capabilities for ingress, secrets, configmaps, and workload management
+
+### 4. Identity Management Evolution
+- **Phase 1**: Manual provisioning of VPN access and Kubernetes ServiceAccounts/Users
+- **Phase 2**: Migration to Keycloak-based identity management (aligning with ADR-006) for centralized authentication and lifecycle management
+
+### 5. Harmony Integration
+- **TenantScore implementation**: Declarative tenant provisioning using Harmony's Score/Interpret pattern
+- **Topology abstraction**: Tenant configuration abstracted from underlying Kubernetes implementation details
+- **Automated deployment**: Complete tenant setup automated through Harmony's orchestration capabilities
+
+## Rationale
+
+### Network Security Through VPN Access
+- **Defense in depth**: VPN requirement adds critical security layer preventing unauthorized cluster access
+- **Simplified firewall rules**: No need for complex public endpoint protections or rate limiting
+- **Audit capability**: VPN access provides clear audit trail of cluster connections
+- **Aligns with enterprise practices**: Most enterprise customers already use VPN infrastructure
+
+### Namespace Isolation vs Virtual Control Planes
+Following Kubernetes official guidance, namespace isolation provides:
+- **Lower resource overhead**: Virtual control planes require dedicated etcd, API server, and controller manager per tenant
+- **Operational simplicity**: Single control plane to maintain, upgrade, and monitor
+- **Cross-tenant service integration**: Enables future controlled cross-tenant communication if required
+- **Proven stability**: Namespace-based isolation is well-tested and widely deployed
+- **Cost efficiency**: Significantly lower infrastructure costs compared to dedicated control planes
+
+### Hybrid Tenancy Model Suitability
+Our approach addresses both customer and team multi-tenancy requirements:
+- **Customer isolation**: Strong network and RBAC boundaries prevent cross-tenant interference
+- **Team collaboration**: Multiple team members can share namespace access through group-based RBAC
+- **Self-service balance**: Controlled API access enables client autonomy without compromising security
+
+### Harmony Architecture Alignment
+- **Provider agnostic**: TenantScore abstracts multi-tenancy concepts, enabling future support for other Kubernetes distributions
+- **Hexagonal architecture**: Tenant management becomes an infrastructure capability accessed through well-defined ports
+- **Declarative automation**: Tenant lifecycle fully managed through Harmony's Score execution model
+
+## Consequences
+
+### Positive Consequences
+- **Strong security posture**: VPN + namespace isolation provides robust tenant separation
+- **Operational efficiency**: Single cluster management with automated tenant provisioning
+- **Client autonomy**: Self-service capabilities reduce operational support burden
+- **Scalable architecture**: Can support hundreds of tenants per cluster without architectural changes
+- **Future flexibility**: Foundation supports evolution to more sophisticated multi-tenancy models
+- **Cost optimization**: Shared infrastructure maximizes resource utilization
+
+### Negative Consequences
+- **VPN operational overhead**: Requires VPN infrastructure management
+- **Manual provisioning complexity**: Phase 1 manual user management creates administrative burden
+- **Network policy dependency**: Requires CNI with NetworkPolicy support (OVN-Kubernetes provides this and is the OKD/Openshift default)
+- **Cluster-wide resource limitations**: Some advanced Kubernetes features require cluster-wide access
+- **Single point of failure**: Cluster outage affects all tenants simultaneously
+
+### Migration Challenges
+- **Legacy client integration**: Existing clients may need VPN client setup and credential migration
+- **Monitoring complexity**: Per-tenant observability requires careful metric and log segmentation
+- **Backup considerations**: Tenant data backup must respect isolation boundaries
+
+## Alternatives Considered
+
+### Alternative 1: Virtual Control Plane Per Tenant
+**Pros**: Complete control plane isolation, full Kubernetes API access per tenant
+**Cons**: 3-5x higher resource usage, complex cross-tenant networking, operational complexity scales linearly with tenants
+
+**Rejected**: Resource overhead incompatible with cost-effective multi-tenancy goals
+
+### Alternative 2: Dedicated Clusters Per Tenant
+**Pros**: Maximum isolation, independent upgrade cycles, simplified security model
+**Cons**: Exponential operational complexity, prohibitive costs, resource waste
+
+**Rejected**: Operational overhead makes this approach unsustainable for multiple clients
+
+### Alternative 3: Public API with Advanced Authentication
+**Pros**: No VPN requirement, potentially simpler client access
+**Cons**: Larger attack surface, complex rate limiting and DDoS protection, increased security monitoring requirements
+
+**Rejected**: Risk/benefit analysis favors VPN-based access control
+
+### Alternative 4: Service Mesh Based Isolation
+**Pros**: Fine-grained traffic control, encryption, advanced observability
+**Cons**: Significant operational complexity, performance overhead, steep learning curve
+
+**Rejected**: Complexity overhead outweighs benefits for current requirements; remains option for future enhancement
+
+## Additional Notes
+
+### Implementation Roadmap
+1. **Phase 1**: Implement VPN access and manual tenant provisioning
+2. **Phase 2**: Deploy TenantScore automation for namespace, RBAC, and NetworkPolicy management
+3. **Phase 3**: Integrate Keycloak for centralized identity management
+4. **Phase 4**: Add advanced monitoring and per-tenant observability
+
+### TenantScore Structure Preview
+```rust
+pub struct TenantScore {
+    pub tenant_config: TenantConfig,
+    pub resource_quotas: ResourceQuotaConfig,
+    pub network_isolation: NetworkIsolationPolicy,
+    pub storage_access: StorageAccessConfig,
+    pub rbac_config: RBACConfig,
+}
+```
+
+### Future Enhancements
+- **Cross-tenant service mesh**: For approved inter-tenant communication
+- **Advanced monitoring**: Per-tenant Prometheus/Grafana instances
+- **Backup automation**: Tenant-scoped backup policies
+- **Cost allocation**: Detailed per-tenant resource usage tracking
+
+This ADR establishes the foundation for secure, scalable multi-tenancy in Harmony-managed clusters while maintaining operational simplicity and cost effectiveness. A follow-up ADR will detail the Tenant abstraction and user management mechanisms within the Harmony framework.
