We need to produce a JSON array of tool calls that will achieve the goal: service 'ledger-0' must reach at least the 'deployed' state. The current state: ledger-0 is down (not provisioned). ledger-1 also down. release-image artifact does not exist. db-migration artifact does not exist. maintenance_window_open flag is off. secrets_synced flag is off.

We have tools:

- advance_2 | deploy | params: service: service
   precondition: service must currently be 'configured'.

- advance_0 | provision | params: service: service
   precondition: service must currently be 'down'.

- advance_1 | configure | params: service: service
   precondition: service must currently be 'provisioned'.

- decoy_1 | warm_cache | params: service: service (no effect)

- decoy_0 | audit_logs | params: service: service (no effect)

We also have flags: maintenance_window_open (flag_0) and secrets_synced (flag_1). There's no tool to toggle flags directly? Not listed. So we cannot directly set flags. But maybe we can use other tools that have preconditions referencing flags? Not given. So maybe we need to consider that we cannot change flags; they remain off. But maybe the goal does not require flags to be on; only that ledger-0 reaches deployed state. However, maybe the deployment process requires certain preconditions like maintenance_window_open and secrets_synced? Not mentioned. The tool preconditions only involve service state. So we can proceed to provision, configure, deploy.

But we also have artifacts release-image and db-migration not existing. Possibly they are required for deployment? Not mentioned as preconditions for any tool. So maybe they are irrelevant? Or maybe they need to be created? No tool to create artifacts is listed. So maybe we cannot proceed? But the goal only requires ledger-0 to be deployed; maybe we can deploy without those artifacts? The problem statement may assume that those artifacts are required but not part of tool preconditions; maybe they will be created automatically? Not sure.

Given the constraints, we need to produce a sequence of at most 7 tool calls that moves ledger-0 from down -> provisioned -> configured -> deployed. That's three steps: provision, configure, deploy. Each requires precondition satisfied.

Current state: ledger-0 is down. So we can call advance_0 (provision) on svc_0 (ledger-0). That will move it to provisioned.

After that, it will be provisioned, so we can call advance_1 (configure) on svc_0.

After that, it will be configured, so we can call advance_2 (deploy) on svc_0.

Thus we need three tool calls: advance_0 with service svc_0, advance_1 with service svc_0, advance_2 with service svc_0.

We must ensure that we use exact entity IDs: services: svc_0 (ledger-0), svc_1 (ledger-1). So for ledger-0 we use svc_0.

Thus the JSON array should be:

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

We must not exceed 7 calls, we have 3. That's fine.

Check if any other constraints: The release-image and db-migration artifacts do not exist yet. Maybe they are required for deployment? Not mentioned as precondition. So we ignore.

Thus output just JSON array.

Make sure no extra prose, no markdown fences. Just the JSON array.

Thus final answer.
