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. Entity IDs: services svc_0 (billing-0), svc_1 (registry-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 yet 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.

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

We need to use tool calls to progress from current state to healthy for svc_0.

Tool catalog:

- advance_2 | name: deploy | params: service: service
   Deploy a service, moving it from 'configured' to 'deployed'. Precondition: the service must currently be 'configured'.

- advance_1 | name: configure | params: service: service
   Configure a service, moving it from 'provisioned' to 'configured'. Precondition: the service must currently be 'provisioned'.

- build_art_0 | name: build_artifact | params: artifact: artifact
   Build the art_0 artifact (moves it from 'absent' to 'built'). Precondition: the artifact must be 'absent'.

- advance_3 | name: health-check | params: service: service
   Health-check a service, moving it from 'deployed' to 'healthy'. Precondition: the service must currently be 'deployed'. Requires the flag_0 flag to be set. Requires the art_0 artifact to be published.

- decoy_0 | name: audit_logs | params: service: service
   Audit the log stream for a service (read-only). (Has no effect on deployment state.)

- set_flag_0 | name: set_flag | params: flag: flag
   Set the flag_0 flag to true. Precondition: it must currently be false.

- publish_art_0 | name: publish_artifact | params: artifact: artifact
   Publish the art_0 artifact (moves it from 'built' to 'published'). Precondition: the artifact must be 'built'.

- id: advance_0 | name: provision | params: service: service
   Provision a service, moving it from 'down' to 'provisioned'. Precondition: the service must currently be 'down'.

- id: decoy_1 | name: warm_cache | params: service: service
   Warm the cache for a service (best-effort, no state change). (Has no effect on deployment state.)

We can use at most 14 tool calls.

We need to produce a JSON array of tool calls that, executed in order from the current state, satisfies the goal.

We need to consider preconditions.

Current state details:

- billing-0 is down (not yet provisioned). So it's in 'down' state. There's also provisioned? Not yet. So we need to provision it first: advance_0 (provision) with service svc_0. Precondition: service must be 'down'. That's satisfied.

- After provision, it becomes 'provisioned'.

- Then we need to configure it: advance_1 (configure) with service svc_0. Precondition: service must be 'provisioned'. That will move it to 'configured'.

- Then we need to deploy it: advance_2 (deploy) with service svc_0. Precondition: service must be 'configured'. That moves it to 'deployed'.

- Then we need to health-check it: advance_3 (health-check) with service svc_0. Precondition: service must be 'deployed', flag_0 must be set (true), and art_0 artifact must be published.

Thus we need to ensure flag_0 is set to true, and art_0 is published.

Flag_0 is maintenance_window_open flag. Currently it's off (false). So we need to set_flag_0 (set_flag) with flag flag_0. Precondition: it must currently be false. That's satisfied.

Artifact art_0 (release-image) does not exist yet. So we need to build it: build_art_0 (build_artifact) with artifact art_0. Precondition: artifact must be 'absent'. That's satisfied. After building, it becomes 'built'.

Then we need to publish it: publish_art_0 (publish_artifact) with artifact art_0. Precondition: artifact must be 'built'. That's satisfied after building.

Now we have flag_0 set to true, and art_0 published.

Now we can health-check svc_0: advance_3 with service svc_0.

Thus the sequence:

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

That's 7 tool calls. All preconditions satisfied.

Check that we haven't used any other tools unnecessarily. We could also use decoy_0 or decoy_1 but not needed.

We must output only a JSON array of tool calls, each element an object {"tool": "<tool id>", "args": {"<param>": "<entity id>", ...}}.

The tool IDs are given as "advance_0", "advance_1", "advance_2", "build_art_0", "publish_art_0", "set_flag_0", "advance_3". The names are not needed; just the IDs.

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

Similarly, advance_1: {"service":"svc_0"}.

Advance_2: {"service":"svc_0"}.

Set_flag_0: {"flag":"flag_0"}.

Build_art_0: {"artifact":"art_0"}.

Publish_art_0: {"artifact":"art_0"}.

Advance_3: {"service":"svc_0"}.

Thus the JSON array:

[
  {"tool":"advance_0","args":{"service":"svc_0"}},
  {"tool":"advance_1","args":{"service":"svc_0"}},
  {"tool":"advance_2","args":{"service":"svc_0"}},
  {"tool":"set_flag_0","args":{"flag":"flag_0"}},
  {"tool":"build_art_0","args":{"artifact":"art_0"}},
  {"tool":"publish_art_0","args":{"artifact":"art_0"}},
  {"tool":"advance_3","args":{"service":"svc_0"}}
]

Check that we haven't exceeded 14 calls; we have 7.

All preconditions satisfied at each step? Let's verify:

- Step 1: advance_0 provision svc_0: precondition: service must be 'down'. Currently billing-0 is down. So okay.

- After step 1, service becomes provisioned.

- Step 2: advance_1 configure svc_0: precondition: service must be 'provisioned'. Now it is provisioned. So okay.

- After step 2, service becomes configured.

- Step 3: advance_2 deploy svc_0: precondition: service must be 'configured'. Now it is configured. So okay.

- After step 3, service becomes deployed.

- Step 4: set_flag_0 flag_0: precondition: flag must be false. Currently maintenance_window_open is off (false). So okay.

- After step 4, flag_0 becomes true.

- Step 5: build_art_0 artifact art_0: precondition: artifact must be 'absent'. Currently release-image does not exist (absent). So okay.

- After step 5, artifact becomes built.

- Step 6: publish_art_0 artifact art_0: precondition: artifact must be 'built'. Now it is built. So okay.

- After step 6, artifact becomes published.

- Step 7: advance_3 health-check svc_0: precondition: service must be 'deployed', flag_0 must be set (true), and art_0 artifact must be published. All satisfied. So okay.

Thus the plan works.

We must output only the JSON array, no extra text.

Thus final answer is the JSON array as above.
