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

Goal: service 'notifier-0' must reach at least the 'healthy' state. To get to healthy, we need to go through provision -> configure -> deploy -> health-check. Health-check precondition: service must be 'deployed', flag_0 must be set, and art_0 artifact must be published. So we need to provision notifier-0, configure it, deploy it, then health-check it, ensuring flag_0 is set and art_0 is published.

We also need to ensure that the release-image artifact exists and is published. The artifact art_0 is release-image. We need to build it (build_art_0) then publish it (publish_art_0). Also maybe need to build db-migration artifact? Not required for notifier-0 health-check, but maybe needed for other steps? The health-check precondition only requires art_0 published, not db-migration. So we can ignore db-migration.

We also need to set flag_0 (maintenance_window_open) to true. Currently it's off (false). So we need to set_flag_0.

We also need to ensure that the flag_0 precondition for health-check is satisfied (must be set). So we must set_flag_0 before health-check.

Also health-check requires flag_0 to be set (i.e., true). So we need to set_flag_0.

Also health-check requires art_0 published. So we need to build_art_0 then publish_art_0.

Also health-check requires service to be deployed. So we need to provision, configure, deploy.

Thus sequence:

1. advance_0 provision svc_0 (notifier-0) - precondition: service is down. It is down, so okay.

2. advance_1 configure svc_0 - precondition: service is provisioned. After step 1, it's provisioned, so okay.

3. advance_2 deploy svc_0 - precondition: service is configured. After step 2, it's configured, so okay.

Now we need to build artifact art_0 (release-image). It is absent. So we can build_art_0 artifact art_0.

4. build_art_0 artifact art_0.

5. publish_art_0 artifact art_0 - precondition: artifact must be built. After step 4, it's built, so okay.

6. set_flag_0 flag flag_0 - precondition: flag must be false. It's off, so okay.

Now we can health-check svc_0. Health-check precondition: service must be deployed (yes), flag_0 must be set (yes), art_0 must be published (yes). So:

7. advance_3 health-check service svc_0.

That's it. That's 7 tool calls. All preconditions satisfied.

Check that we didn't need to set secrets_synced flag? Not required for health-check. The goal only mentions service healthy. No other constraints.

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

Parameters: For advance_0, param is service: service. So args: {"service":"svc_0"}.

Similarly configure: service: service.

Deploy: service: service.

build_art_0: artifact: artifact.

publish_art_0: artifact: artifact.

set_flag_0: flag: flag.

health-check: service: service.

Thus JSON array:

[
  {"tool":"advance_0","args":{"service":"svc_0"}},
  {"tool":"advance_1","args":{"service":"svc_0"}},
  {"tool":"advance_2","args":{"service":"svc_0"}},
  {"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_3","args":{"service":"svc_0"}}
]

Check that we used at most 14 calls, we used 7.

All preconditions satisfied? Let's double-check each step's precondition at the moment of call.

Initial state: notifier-0 down, not provisioned. So advance_0 precondition: service must be down. Yes.

After advance_0, service becomes provisioned. Then advance_1 precondition: service must be provisioned. Yes.

After advance_1, service becomes configured. Then advance_2 precondition: service must be configured. Yes.

Artifact art_0 is absent initially. build_art_0 precondition: artifact must be absent. Yes.

After build_art_0, artifact is built. publish_art_0 precondition: artifact must be built. Yes.

Flag_0 is off (false). set_flag_0 precondition: flag must be false. Yes.

After set_flag_0, flag_0 is true. Health-check precondition: service must be deployed (yes), flag_0 must be set (true), art_0 must be published (yes). So health-check can be called.

Thus plan works.

We must output only JSON array, no extra text. Ensure proper JSON formatting, no trailing commas.

Thus final answer.
