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 yet provisioned). ledger-1 also 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 have tools:

- advance_2: deploy service, moving from 'configured' to 'deployed'. Precondition: service must currently be 'configured'.

- decoy_1: warm_cache, no effect.

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

- decoy_0: audit_logs, no effect.

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

We need to get ledger-0 to 'deployed' state. That requires it to be 'configured' first, then deploy. So steps: provision ledger-0 (down -> provisioned). Then configure ledger-0 (provisioned -> configured). Then deploy ledger-0 (configured -> deployed). However, there may be preconditions about artifacts and flags? The goal only mentions service state; but maybe the deployment requires release-image artifact existence? Not explicitly in tool preconditions, but maybe the environment expects that artifacts exist before deployment? The problem statement didn't specify preconditions beyond the tool definitions. It only says each tool has typed parameters and PRECONDITIONS that must hold at the moment you call it; calling a tool whose preconditions are not met is an error and your plan fails. The tool definitions only list precondition about service state. No mention of artifact existence or flags. So we can ignore those? But maybe the deployment tool also requires the artifact to exist? Not mentioned. So we can just provision, configure, deploy.

But we also have flags: maintenance_window_open and secrets_synced. Possibly needed for deployment? Not mentioned in tool preconditions. So maybe they are irrelevant. However, the goal may require them to be on? The goal only says service 'ledger-0' must reach at least the 'deployed' state. No mention of flags. So we can ignore them.

But maybe the deployment tool (advance_2) requires the service to be 'configured', which we can achieve via configure (advance_1). That requires service to be 'provisioned' (advance_0). So sequence: provision svc_0, configure svc_0, deploy svc_0. That's three tool calls. That's within 7.

We must use exact entity IDs: service ids are svc_0 (ledger-0), svc_1 (ledger-1). So we will use svc_0 for ledger-0.

Tool IDs: advance_0 is provision, advance_1 is configure, advance_2 is deploy.

Thus plan: ["advance_0", {"service":"svc_0"}], then ["advance_1", {"service":"svc_0"}], then ["advance_2", {"service":"svc_0"}].

We must output JSON array of objects each with "tool": "<tool id>", "args": {...}. No extra text.

Thus output:

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

Make sure it's valid JSON array. No extra whitespace? It's okay.

Check that each tool call's precondition holds at that point.

Initially, ledger-0 is down. So provision (advance_0) precondition: service must be down. Yes. After provision, service becomes provisioned.

Then configure (advance_1) precondition: service must be provisioned. Yes.

Then deploy (advance_2) precondition: service must be configured. Yes.

Thus plan works.

We must not exceed 7 calls; we use 3.

Thus final answer is just that JSON array.
