We need to produce a JSON array of tool calls to achieve goal: service 'gateway-0' must reach at least 'healthy' state. Entities: service svc_0 (gateway-0), svc_1 (gateway-1). Artifacts: art_0 (release-image), art_1 (db-migration). Flags: flag_0 (maintenance_window_open), flag_1 (secrets_synced). Current state: gateway-0 is down (not provisioned). gateway-1 down. release-image artifact does not exist yet. db-migration artifact does not exist yet. maintenance_window_open flag is off. secrets_synced flag is off.

We need to use tools: provision (advance_0) moves from down to provisioned. configure (advance_1) moves from provisioned to configured. deploy (advance_2) moves from configured to deployed. health-check (advance_3) moves from deployed to healthy.

We need to ensure preconditions hold at each step. Also we may need to set flags? There's no tool to set flags; they are just flags that must be on at the end? The goal only mentions service 'gateway-0' must reach at least 'healthy' state. It doesn't require flags to be on? The goal says "all conditions must hold at the end". The conditions are the goal: service 'gateway-0' must reach at least the 'healthy' state. That's the only condition? The problem statement: "GOAL (all conditions must hold at the end): - service 'gateway-0' must reach at least the 'healthy' state". So only that condition. However there may be implicit preconditions about flags? Not required. But maybe the environment expects flags to be on? Not mentioned as part of goal. So we can ignore flags.

But we might need to create artifacts? There's no tool to create artifacts; they just exist or not. The current state says they do not exist yet. But maybe we need to have them exist before some steps? Not required for deploying gateway-0? Possibly the deployment process requires artifacts to be present? Not specified. The tool preconditions only involve service state. So we can ignore artifacts.

Thus we need to move svc_0 from down -> provisioned -> configured -> deployed -> healthy. That's 4 steps, using tools advance_0, advance_1, advance_2, advance_3 respectively, each with service param svc_0.

We must ensure each precondition holds at the moment we call. Initially svc_0 is down, so provision is allowed. After provision, it becomes provisioned, then configure is allowed. After configure, it becomes configured, then deploy is allowed. After deploy, it becomes deployed, then health-check is allowed. So sequence: provision (advance_0) on svc_0, configure (advance_1) on svc_0, deploy (advance_2) on svc_0, health-check (advance_3) on svc_0.

We can also optionally do other steps for svc_1? Not needed. But we must not exceed 8 calls. So 4 calls is fine.

We must output JSON array of objects each with "tool": "<tool id>", "args": {"<param>": "<entity id>", ...}. The tool ids are given: advance_0, advance_1, advance_2, advance_3. The param is service: service. So args should be {"service": "svc_0"} etc.

Thus output:

[
  {"tool":"advance_0","args":{"service":"svc_0"}},
  {"tool":"advance_1","args":{"service":"svc_0"}},
  {"tool":"advance_2","args":{"service":"svc_0"}},
  {"tool":"advance_3","args":{"service":"svc_0"}}
]

Make sure JSON array only, no extra text. Ensure proper quoting. No markdown fences.

Let's produce that.
