We need to produce a JSON array of tool calls that will achieve the goal: service 'billing-0' must reach at least the 'healthy' state. Use exact entity IDs: services svc_0 (billing-0), svc_1 (webhooks-1); artifacts art_0 (release-image), art_1 (db-migration); flags flag_0 (maintenance_window_open), flag_1 (secrets_synced).

Current state: billing-0 is down (not provisioned). webhooks-1 down. release-image artifact does not exist yet (absent). db-migration artifact does not exist yet (absent). maintenance_window_open flag is off (false). secrets_synced flag is off (false).

Goal: service 'billing-0' must reach at least the 'healthy' state.

We need to produce a plan using at most 14 tool calls, each with tool id and args.

We need to consider preconditions.

Let's outline steps:

We need to get the release-image artifact built and published, because health-check requires art_0 published and flag_0 set. Also need to configure and deploy billing-0.

Current state:

- svc_0 is down.
- svc_1 is down.
- art_0 is absent.
- art_1 is absent.
- flag_0 is false.
- flag_1 is false.

Goal: svc_0 healthy.

We need to go through states: down -> provisioned -> configured -> deployed -> healthy.

But we also need to build artifact art_0 (release-image) before publishing it. Then publish it. Then set flag_0 to true (maintenance_window_open). Then health-check.

But also need to configure and deploy svc_0. Let's see the tool sequence:

- advance_2: deploy service (requires service configured). Actually deploy moves from configured to deployed. So we need to first configure service (advance_1) which moves from provisioned to configured. But provisioning must happen first (advance_0) moving from down to provisioned. So steps:

1. Build artifact art_0 (build_art_0) - precondition: artifact must be absent. It is absent, so can build. This moves it to built.

2. Publish artifact art_0 (publish_art_0) - precondition: artifact must be built. After build, it's built, so can publish, moving to published.

3. Set flag_0 (set_flag_0) - precondition: flag must be false. It's false, so can set to true.

Now we can configure svc_0: need to provision it first (advance_0) - precondition: service must be down. It is down, so can provision, moving to provisioned.

Then configure (advance_1) - precondition: service must be provisioned. After provision, it's provisioned, so can configure, moving to configured.

Then deploy (advance_2) - precondition: service must be configured. After configure, it's configured, so can deploy, moving to deployed.

Then health-check (advance_3) - precondition: service must be deployed and flag_0 true and art_0 published. After deploy, it's deployed, flag_0 is true, art_0 published, so can health-check, moving to healthy.

We also might need to handle webhooks-1? Not required for goal, but maybe we need to ensure we don't break anything? The goal only cares about billing-0 healthy. However, some preconditions might involve other services? The health-check precondition only requires flag_0 and art_0 published; no other services. So we can ignore webhooks-1.

But we need to ensure we don't exceed 14 calls. Let's count:

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

That's 7 calls. All preconditions satisfied sequentially.

But we need to ensure that after each call, the state updates accordingly for next precondition.

Let's simulate:

Initial:
- art_0: absent
- art_0 built? no
- art_0 published? no
- flag_0: false
- svc_0: down
- svc_0 provisioned? no
- svc_0 configured? no
- svc_0 deployed? no
- svc_0 healthy? no

Step 1: build_art_0 (artifact: art_0) -> moves from absent to built. Precondition satisfied (absent). After: art_0 built.

Step 2: publish_art_0 (artifact: art_0) -> precondition: artifact must be built. Yes. Moves to published.

Step 3: set_flag_0 (flag: flag_0) -> precondition: flag must be false. It's false. Sets to true.

Step 4: advance_0 (service: svc_0) -> precondition: service must be down. It's down. Moves to provisioned.

Step 5: advance_1 (service: svc_0) -> precondition: service must be provisioned. Yes. Moves to configured.

Step 6: advance_2 (service: svc_0) -> precondition: service must be configured. Yes. Moves to deployed.

Step 7: advance_3 (service: svc_0) -> precondition: service must be deployed, flag_0 true, art_0 published. All satisfied. Moves to healthy.

Goal achieved.

We must output JSON array of objects with "tool": "<tool id>", "args": {...}. Use exact tool ids: build_art_0, publish_art_0, set_flag_0, advance_0, advance_1, advance_2, advance_3.

Parameter names: artifact, service, flag. The tool definitions show params: artifact: artifact, service: service, flag: flag. So args should be {"artifact":"art_0"} etc.

Make sure to use exact ids: artifact: art_0, service: svc_0, flag: flag_0.

Thus 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"}}
]

Check that we didn't exceed 14 calls; we have 7.

Make sure no extra prose. Just JSON array.

Thus final answer.
