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 service, moving from 'configured' to 'deployed'. Precondition: service must currently be 'configured'.

- advance_0: provision service, moving from 'down' to 'provisioned'. Precondition: service must currently be 'down'.

- advance_1: configure service, moving from 'provisioned' to 'configured'. Precondition: service must currently be 'provisioned'.

- decoy_1: warm_cache (no effect)

- decoy_0: audit_logs (no effect)

Goal: ledger-0 must reach at least 'deployed' state. That means we need to get it to 'deployed' state. The deployment pipeline likely: down -> provision -> configure -> configured? Actually advance_1 moves from provisioned to configured. Then deploy (advance_2) moves from configured to deployed. So we need to go down -> provision -> configure -> deploy.

But we also have constraints: release-image artifact does not exist yet. Probably needed for provision? Not mentioned but maybe needed as precondition? Not listed. The only preconditions given are the service state. However maybe there are hidden preconditions like artifact existence? Not mentioned. The problem only lists preconditions as service state. So we can ignore artifact existence.

But we also have flags: maintenance_window_open is off, secrets_synced is off. Possibly needed for some steps? Not mentioned as preconditions for any tool. So maybe they are irrelevant? But maybe they are needed to enable something else? Not specified.

Goal only requires ledger-0 deployed. So we need to sequence calls to get ledger-0 from down to deployed.

Sequence:

1. provision ledger-0 (advance_0) - precondition: service must be down. It is down, so ok.

2. configure ledger-0 (advance_1) - precondition: service must be provisioned. After step 1, it is provisioned, so ok.

3. deploy ledger-0 (advance_2) - precondition: service must be configured. After step 2, it is configured, so ok.

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

But we must use exact entity IDs: Services: svc_0 (ledger-0), svc_1 (ledger-1). So we use svc_0.

Thus JSON array:

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

Check constraints: at most 7 calls, we have 3. All preconditions satisfied at time of call.

But we must ensure that after each call, the state changes accordingly. The initial state: ledger-0 is down. So first call advance_0 is allowed. After that, ledger-0 becomes provisioned. Then advance_1 is allowed (needs provisioned). After that, ledger-0 becomes configured. Then advance_2 is allowed (needs configured). After that, ledger-0 becomes deployed, meeting goal.

Thus answer is that JSON array.

Make sure no extra fields, no prose. Just JSON array.

Thus final.
