status: complete

owner: peerB (impl), peerA (spec via Aux)
goal: Create fiberlb spec and implementation scaffolding

description: |
  Final "Later" phase deliverable. FiberLB is the load balancer layer.
  Load balancing is critical for high availability and traffic distribution.
  Follow established pattern: spec → scaffold.

  Context:
  - fiberlb = L4/L7 load balancer service
  - Multi-tenant design (org/project scoping)
  - Integrates with aegis (IAM) for auth
  - ChainFire for config storage

acceptance:
  - Specification document at specifications/fiberlb/README.md (pending)
  - Cargo workspace with fiberlb-* crates compiles
  - Core types (Listener, Pool, Backend, HealthCheck) defined
  - Proto definitions for LoadBalancerService
  - gRPC management API scaffold

steps:
  # Phase 1 - Specification (Aux)
  - step: S1
    action: Create fiberlb specification
    priority: P0
    status: pending
    complexity: medium
    owner: peerA (Aux)
    notes: Pending Aux delegation (spec in parallel)

  # Phase 2 - Scaffolding (PeerB)
  - step: S2
    action: Create fiberlb workspace
    priority: P0
    status: complete
    complexity: small
    component: fiberlb
    notes: |
      Created fiberlb/Cargo.toml (workspace)
      Crates: fiberlb-types, fiberlb-api, fiberlb-server

  - step: S3
    action: Define core types
    priority: P0
    status: complete
    complexity: small
    component: fiberlb-types
    notes: |
      LoadBalancer, LoadBalancerId, LoadBalancerStatus
      Pool, PoolId, PoolAlgorithm, PoolProtocol
      Backend, BackendId, BackendStatus, BackendAdminState
      Listener, ListenerId, ListenerProtocol, TlsConfig
      HealthCheck, HealthCheckId, HealthCheckType, HttpHealthConfig

  - step: S4
    action: Define proto/fiberlb.proto
    priority: P0
    status: complete
    complexity: small
    component: fiberlb-api
    notes: |
      LoadBalancerService: CRUD for load balancers
      PoolService: CRUD for pools
      BackendService: CRUD for backends
      ListenerService: CRUD for listeners
      HealthCheckService: CRUD for health checks
      ~380 lines proto

  - step: S5
    action: gRPC server scaffold
    priority: P1
    status: complete
    complexity: medium
    component: fiberlb-server
    notes: |
      LoadBalancerServiceImpl, PoolServiceImpl, BackendServiceImpl
      ListenerServiceImpl, HealthCheckServiceImpl
      Main entry with tonic-health on port 9080

  - step: S6
    action: Integration test setup
    priority: P1
    status: complete
    complexity: small
    component: fiberlb
    notes: |
      cargo check passes
      cargo test passes (8 tests)

outcome: |
  COMPLETE: 2025-12-08
  S2-S6 complete (S1 spec pending via Aux).
  Implementation scaffolding complete.

  Final workspace structure:
  - fiberlb/Cargo.toml (workspace with 3 crates)
  - fiberlb-types: LoadBalancer, Pool, Backend, Listener, HealthCheck (~600 lines)
  - fiberlb-api: proto (~380 lines) + lib.rs + build.rs
  - fiberlb-server: 5 gRPC services + main.rs

  Tests: 8 pass
  FiberLB enters "operational" status (scaffold).
  **MILESTONE: 7/7 deliverables now have operational scaffolds.**

notes: |
  FiberLB is the final scaffold for 7/7 deliverable coverage.
  L4 load balancing (TCP/UDP) is core, L7 (HTTP) is future enhancement.
  All cloud platform components now have operational scaffolds.
