We need to produce a JSON array of tool calls that will achieve the goal: service 'ledger-0' must reach at least the 'healthy' state. The current state: ledger-0 is down (not provisioned). registry-1 is 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 with IDs and parameters. Need to plan steps to get ledger-0 to healthy.

Goal: service 'ledger-0' must reach at least the 'healthy' state. The health-check tool moves from 'deployed' to 'healthy', precondition: service must currently be 'deployed', requires flag_0 flag to be set, requires art_0 artifact to be published.

Thus to get ledger-0 to healthy, we need to get it to deployed state first, then health-check.

To get to deployed, we need to deploy it: advance_2 (deploy) moves from 'configured' to 'deployed'. Precondition: service must currently be 'configured'.

To get to configured, we need to configure: advance_1 (configure) moves from 'provisioned' to 'configured'. Precondition: service must currently be 'provisioned'.

To get to provisioned, we need to provision: advance_0 (provision) moves from 'down' to 'provisioned'. Precondition: service must currently be 'down'.

Thus we need to provision ledger-0 (svc_0). That's advance_0 with service: svc_0.

But we also need to ensure that the artifact release-image (art_0) is published before health-check, because health-check requires art_0 artifact to be published. Also requires flag_0 (maintenance_window_open) to be set. Also requires service to be deployed.

Thus we need to build the artifact release-image (art_0) first: build_artifact (build_art_0) moves from 'absent' to 'built'. Precondition: artifact must be 'absent'. That's true currently.

Then publish the artifact: publish_artifact (publish_art_0) moves from 'built' to 'published'. Precondition: artifact must be 'built'.

Then set flag_0 (maintenance_window_open) to true: set_flag_0 (set_flag) with flag: flag_0. Precondition: flag must currently be false. That's true currently.

Then configure ledger-0: advance_1 with service: svc_0 (needs to be provisioned). After provision, it becomes provisioned, then configure moves to configured.

Then deploy ledger-0: advance_2 with service: svc_0 (needs to be configured). After configure, it becomes configured, then deploy moves to deployed.

Then health-check ledger-0: advance_3 with service: svc_0 (needs to be deployed, flag_0 set, art_0 published). After that, it becomes healthy.

We also have db-migration artifact (art_1) not needed? Not required for ledger-0 health, but maybe needed for other steps? Not required. However, the health-check precondition includes art_0 published, not art_1. So we don't need to build or publish art_1.

But we might need to ensure that the artifact release-image is built and published before health-check. So we need to build and publish it before the health-check step.

Also need to set flag_0 before health-check.

Thus order:

1. build_artifact art_0 (build_art_0 with artifact: art_0)
2. publish_artifact art_0 (publish_art_0 with artifact: art_0)
3. set_flag_0 (set_flag with flag: flag_0)
4. provision ledger-0 (advance_0 with service: svc_0)
5. configure ledger-0 (advance_1 with service: svc_0)
6. deploy ledger-0 (advance_2 with service: svc_0)
7. health-check ledger-0 (advance_3 with service: svc_0)

That's 7 tool calls. All preconditions satisfied? Let's verify each step's precondition at the moment.

Initial state:

- ledger-0 is down (not provisioned). So it's 'down' state. That matches precondition for advance_0 (provision) which requires service must be 'down'. Good.

- registry-1 is down but we don't need it.

- release-image artifact does not exist yet (absent). So build_artifact precondition satisfied.

- db-migration artifact does not exist yet (absent). Not needed.

- maintenance_window_open flag is off (false). So set_flag precondition satisfied.

- secrets_synced flag is off (false). Not needed.

Thus step 1: build_artifact art_0 (artifact: art_0). Moves artifact from absent to built.

Step 2: publish_artifact art_0 (artifact: art_0). Precondition: artifact must be built. After step 1, it is built, so okay.

Step 3: set_flag_0 (flag: flag_0). Precondition: flag must be false. It is false, okay.

Step 4: provision ledger-0 (advance_0 service: svc_0). Precondition: service must be down. It is down, okay. After this, service becomes provisioned.

Step 5: configure ledger-0 (advance_1 service: svc_0). Precondition: service must be provisioned. After step 4, it is provisioned, okay. After this, it becomes configured.

Step 6: deploy ledger-0 (advance_2 service: svc_0). Precondition: service must be configured. After step 5, it is configured, okay. After this, it becomes deployed.

Step 7: health-check ledger-0 (advance_3 service: svc_0). Precondition: service must be deployed, flag_0 must be set, art_0 must be published. All satisfied after steps 2 and 3. So okay. After this, it becomes healthy.

Thus we have a valid plan of 7 calls.

We must output JSON array of objects each with "tool": "<tool id>", "args": {...}. The args must include the parameter(s) as per tool definitions.

Let's map each tool ID to the correct args:

- build_art_0: name: build_artifact, params: artifact: artifact. So args: {"artifact": "art_0"}.

- publish_art_0: name: publish_artifact, params: artifact: artifact. So args: {"artifact": "art_0"}.

- set_flag_0: name: set_flag, params: flag: flag. So args: {"flag": "flag_0"}.

- advance_0: name: provision, params: service: service. So args: {"service": "svc_0"}.

- advance_1: name: configure, params: service: service. So args: {"service": "svc_0"}.

- advance_2: name: deploy, params: service: service. So args: {"service": "svc_0"}.

- advance_3: name: health-check, params: service: service. So args: {"service": "svc_0"}.

Thus the JSON array:

[
  {"tool": "build_art_0", "args": {"artifact": "art_0"}},
  {"tool": "publish_art_0", "args": {"artifact": "art_0"}},
  {"tool": "set_flag_0", "args": {"flag": "flag_0"}},
  {"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 no extra whitespace? It's okay.

We must output only the JSON array, no extra text. Ensure it's valid JSON.

Thus final answer.
