+# Specification: Fix LiteFS Configuration and Process Management (`fix_litefs_config`)
+
+## Overview
+Reconfigure the Navidrome/LiteFS process management to ensure Navidrome and its Consul service registration only occur on the Primary node. This will be achieved by leveraging the LiteFS `exec` block and updating the `entrypoint.sh` logic. Additionally, correct the Navidrome database and storage paths to properly utilize the LiteFS replicated mount.
+
+## Functional Requirements
+- **LiteFS Configuration (`litefs.yml`):**
+    - Enable the `exec` block to trigger `/usr/local/bin/entrypoint.sh`.
+    - This allows LiteFS to manage the lifecycle of the application.
+- **Entrypoint Logic (`entrypoint.sh`):**
+    - Implement a supervision loop that monitors leadership via the `/data/.primary` file.
+    - **On Primary:**
+        - Register the node as the `navidrome` (primary) service in Consul.
+        - Start the Navidrome process.
+    - **On Replica:**
+        - Ensure Navidrome is NOT running.
+        - Deregister the `navidrome` primary service if previously registered.
+        - (Optional) Register as a replica service or simply wait.
+    - **On Transition:** Handle graceful shutdown of Navidrome if the node loses leadership.
+- **Storage and Path Configuration (`navidrome-litefs-v2.nomad`):**
+    - Set `ND_DATAFOLDER` to `/data` (the LiteFS FUSE mount).
+    - Set `ND_CACHEFOLDER` to `/shared_data/cache` (shared persistent storage).
+    - Set `ND_BACKUP_PATH` to `/shared_data/backup` (shared persistent storage).
+- **Dockerfile Updates:**
+    - Update `ENTRYPOINT` to `["litefs", "mount"]` to allow LiteFS to act as the supervisor.
+
+## Non-Functional Requirements
+- **Robustness:** Use a simple bash loop for process management to avoid extra dependencies.
+- **Signal Handling:** Ensure signals (SIGTERM) are correctly forwarded to Navidrome for graceful shutdown.
+
+## Acceptance Criteria
+- [ ] Navidrome process runs ONLY on the Primary node.
+- [ ] Consul service `navidrome` correctly points to the current Primary.
+- [ ] Navidrome database (`navidrome.db`) is confirmed to be on the `/data` mount.
+- [ ] Cluster failover correctly stops Navidrome on the old primary and starts it on the new one.
+
+## Out of Scope
+- Implementation of complex init systems like `tini` (bash loop selected by user).

+# Specification: Implement TTL Heartbeat Service Registration (`implement_ttl_heartbeat`)
+
+## Overview
+Replace the current "register and forget" Consul registration logic with a robust "TTL Heartbeat" pattern. This ensures that only the active Primary node is registered in Consul, and service entries are automatically removed (deregistered) if the node crashes, failover occurs, or Nomad stops the allocation.
+
+## Functional Requirements
+- **Supervisor Script (`entrypoint.sh`):**
+    - Refactor to implement the "Self-Registration" pattern with TTL checks.
+    - **Leadership Detection:** Monitor `/data/.primary` (LiteFS 0.5).
+        - **Primary:** Absence of file. Start Navidrome, register service with TTL.
+        - **Replica:** Presence of file. Stop Navidrome, deregister service.
+    - **Heartbeat:** Periodically (e.g., every 5-10s) PUT to Consul to pass the TTL check while Primary.
+    - **Signal Handling:** Trap `SIGTERM`/`SIGINT` to gracefully stop Navidrome and deregister immediately.
+- **Docker Image:**
+    - Ensure `curl` and `jq` are installed (prerequisites for the script).
+- **Nomad Configuration:**
+    - Ensure `NOMAD_IP_http` and `NOMAD_PORT_http` are accessible to the task (standard, but verifying).
+
+## Non-Functional Requirements
+- **Resilience:** The script must handle Consul unavailability gracefully (retries) without crashing the application loop.
+- **Cleanliness:** No "ghost" services. Replicas must not appear in the service catalog.
+
+## Acceptance Criteria
+- [ ] Navidrome runs ONLY on the Primary.
+- [ ] Only ONE `navidrome` service is registered in Consul (pointing to the Primary).
+- [ ] Stopping the Primary allocation results in immediate deregistration (via trap).
+- [ ] Hard killing the Primary allocation results in deregistration after TTL expires (approx 15s).
+- [ ] Replicas do not register any service.
+
+## Implementation Details
+- **Script Name:** We will stick with `entrypoint.sh` for consistency with `litefs.yml` configuration, refactoring its content.
+- **Service ID:** Use `navidrome-${NOMAD_ALLOC_ID}` to ensure uniqueness and traceability.

+# Specification: Update Monitor Discovery Logic (`update_monitor_discovery`)
+
+## Overview
+Refactor the cluster monitoring script (`scripts/cluster_status`) to use Nomad as the primary source of discovery. Currently, the script queries Consul for services, which only shows the Primary node in the new architecture. By querying Nomad allocations first, we can identify all running LiteFS nodes (Primary and Replicas) and then inspect their individual health and replication status.
+
+## Functional Requirements
+- **Nomad Client (`nomad_client.py`):**
+    - Add a function to list all active allocations for a job and extract their host IPs and node names.
+- **Consul Client (`consul_client.py`):**
+    - Modify to allow checking the registration status of a *specific* node/allocation ID rather than just listing all services.
+- **Aggregator (`cluster_aggregator.py`):**
+    - **New Discovery Flow:**
+        1. Query Nomad for all allocations of `navidrome-litefs`.
+        2. For each allocation:
+            - Get the Node Name and IP.
+            - Query the LiteFS API (`:20202`) on that IP for role/DB info.
+            - Query Consul to see if a matching service registration exists (and its health).
+- **Formatter (`output_formatter.py`):**
+    - Handle nodes that are "Standby" (running in Nomad and LiteFS, but not registered in Consul).
+    - Ensure the table correctly displays all 4 nodes.
+
+## Non-Functional Requirements
+- **Efficiency:** Minimize CLI calls by batching Nomad/Consul queries where possible.
+- **Robustness:** Gracefully handle cases where an allocation has no IP yet (starting state).
+
+## Acceptance Criteria
+- [ ] Script output shows all 4 Nomad allocations.
+- [ ] Primary node is clearly identified with its Consul health status.
+- [ ] Replica nodes are shown with their LiteFS role and DB status, even if not in Consul.
+- [ ] Overall cluster health is calculated based on the existence of exactly one Primary and healthy replication on all nodes.
