-# Architecture Decision Record: Higher-Order Topologies
-
-**Initial Author:** Jean-Gabriel Gill-Couture  
-**Initial Date:** 2025-12-08  
-**Last Updated Date:** 2025-12-08  
-
-## Status
-
-Implemented
-
-## Context
-
-Harmony models infrastructure as **Topologies** (deployment targets like `K8sAnywhereTopology`, `LinuxHostTopology`) implementing **Capabilities** (tech traits like `PostgreSQL`, `Docker`).
-
-**Higher-Order Topologies** (e.g., `FailoverTopology<T>`) compose/orchestrate capabilities *across* multiple underlying topologies (e.g., primary+replica `T`).
-
-Naive design requires manual `impl Capability for HigherOrderTopology<T>` *per T per capability*, causing:
-- **Impl explosion**: N topologies × M capabilities = N×M boilerplate.
-- **ISP violation**: Topologies forced to impl unrelated capabilities.
-- **Maintenance hell**: New topology needs impls for *all* orchestrated capabilities; new capability needs impls for *all* topologies/higher-order.
-- **Barrier to extension**: Users can't easily add topologies without todos/panics.
-
-This makes scaling Harmony impractical as ecosystem grows.
-
-## Decision
-
-Use **blanket trait impls** on higher-order topologies to *automatically* derive orchestration:
-
-````rust
-/// Higher-Order Topology: Orchestrates capabilities across sub-topologies.
-pub struct FailoverTopology<T> {
-    /// Primary sub-topology.
-    primary: T,
-    /// Replica sub-topology.
-    replica: T,
-}
-
-/// Automatically provides PostgreSQL failover for *any* `T: PostgreSQL`.
-/// Delegates to primary for queries; orchestrates deploy across both.
-#[async_trait]
-impl<T: PostgreSQL> PostgreSQL for FailoverTopology<T> {
-    async fn deploy(&self, config: &PostgreSQLConfig) -> Result<String, String> {
-        // Deploy primary; extract certs/endpoint;
-        // deploy replica with pg_basebackup + TLS passthrough.
-        // (Full impl logged/elaborated.)
-    }
-
-    // Delegate queries to primary.
-    async fn get_replication_certs(&self, cluster_name: &str) -> Result<ReplicationCerts, String> {
-        self.primary.get_replication_certs(cluster_name).await
-    }
-    // ...
-}
-
-/// Similarly for other capabilities.
-#[async_trait]
-impl<T: Docker> Docker for FailoverTopology<T> {
-    // Failover Docker orchestration.
-}
-````
-
-**Key properties:**
-- **Auto-derivation**: `Failover<K8sAnywhere>` gets `PostgreSQL` iff `K8sAnywhere: PostgreSQL`.
-- **No boilerplate**: One blanket impl per capability *per higher-order type*.
-
-## Rationale
-
-- **Composition via generics**: Rust trait solver auto-selects impls; zero runtime cost.
-- **Compile-time safety**: Missing `T: Capability` → compile error (no panics).
-- **Scalable**: O(capabilities) impls per higher-order; new `T` auto-works.
-- **ISP-respecting**: Capabilities only surface if sub-topology provides.
-- **Centralized logic**: Orchestration (e.g., cert propagation) in one place.
-
-**Example usage:**
-````rust
-// ✅ Works: K8sAnywhere: PostgreSQL → Failover provides failover PG
-let pg_failover: FailoverTopology<K8sAnywhereTopology> = ...;
-pg_failover.deploy_pg(config).await;
-
-// ✅ Works: LinuxHost: Docker → Failover provides failover Docker
-let docker_failover: FailoverTopology<LinuxHostTopology> = ...;
-docker_failover.deploy_docker(...).await;
-
-// ❌ Compile fail: K8sAnywhere !: Docker
-let invalid: FailoverTopology<K8sAnywhereTopology>;
-invalid.deploy_docker(...); // `T: Docker` bound unsatisfied
-````
-
-## Consequences
-
-**Pros:**
-- **Extensible**: New topology `AWSTopology: PostgreSQL` → instant `Failover<AWSTopology>: PostgreSQL`.
-- **Lean**: No useless impls (e.g., no `K8sAnywhere: Docker`).
-- **Observable**: Logs trace every step.
-
-**Cons:**
-- **Monomorphization**: Generics generate code per T (mitigated: few Ts).
-- **Delegation opacity**: Relies on rustdoc/logs for internals.
-
-## Alternatives considered
-
-| Approach | Pros | Cons |
-|----------|------|------|
-| **Manual per-T impls**<br>`impl PG for Failover<K8s> {..}`<br>`impl PG for Failover<Linux> {..}` | Explicit control | N×M explosion; violates ISP; hard to extend. |
-| **Dynamic trait objects**<br>`Box<dyn AnyCapability>` | Runtime flex | Perf hit; type erasure; error-prone dispatch. |
-| **Mega-topology trait**<br>All-in-one `OrchestratedTopology` | Simple wiring | Monolithic; poor composition. |
-| **Registry dispatch**<br>Runtime capability lookup | Decoupled | Complex; no compile safety; perf/debug overhead. |
-
-**Selected**: Blanket impls leverage Rust generics for safe, zero-cost composition.
-
-## Additional Notes
-
-- Applies to `MultisiteTopology<T>`, `ShardedTopology<T>`, etc.
-- `FailoverTopology` in `failover.rs` is first implementation.
