  MVP-K8s achieved (T025 complete). Before production hardening, validate the
  integrated stack with live deployment testing.

  PROJECT.md emphasizes 実戦テスト (practical testing) - this task delivers that.

  Standard engineering principle: validate before harden.
  Smoke test reveals integration issues early, before investing in HA/monitoring.

acceptance:
  - All 9 packages build successfully via nix
  - NixOS modules load without error
  - Services start and pass health checks
  - Cross-component integration verified (FlareDB→IAM→k8shost)
  - Configuration unification validated
  - Deployment issues documented for T027 hardening

steps:
  - step: S1
    name: Environment Setup
    done: NixOS deployment environment ready, all packages build
    status: in_progress
    owner: peerB
    priority: P0
    notes: |
      Prepare clean NixOS deployment environment and verify all packages build.

      Tasks:
      1. Build all 9 packages via nix flake
      2. Verify NixOS modules load without error
      3. Attempt to start systemd services
      4. Document any build/deployment issues

      Success Criteria:
      - 9 packages build: chainfire, flaredb, iam, plasmavmc, novanet, flashdns, fiberlb, lightningstor, k8shost
      - Command: nix build .#chainfire .#flaredb .#iam .#plasmavmc .#novanet .#flashdns .#fiberlb .#lightningstor .#k8shost
      - NixOS modules load without syntax errors
      - Services can be instantiated (even if they fail health checks)

      Non-goals:
      - Service health checks (deferred to S2-S4)
      - Cross-component integration (deferred to S5)
      - Configuration tuning (handled as issues found)

  - step: S2
    name: FlareDB Smoke Test
    done: FlareDB starts, accepts writes, serves reads
    status: pending
    owner: peerB
    priority: P0

  - step: S3
    name: IAM Smoke Test
    done: IAM starts, authenticates users, issues tokens
    status: pending
    owner: peerB
    priority: P0

  - step: S4
    name: k8shost Smoke Test
    done: k8shost starts, creates pods with auth, assigns IPs
    status: pending
    owner: peerB
    priority: P0

  - step: S5
    name: Cross-Component Integration
    done: Full stack integration verified end-to-end
    status: pending
    owner: peerB
    priority: P0

  - step: S6
    name: Config Unification Verification
    done: All components use unified configuration approach
    status: pending

    priority: P0

  T027 (Production Hardening) is BLOCKED until T026 passes.
  Smoke test first, then harden.
