We need to produce a sequence of tool calls leading to billing-0 healthy.

Current state:

- billing-0 (svc_0) is down (not yet provisioned)
- registry-1 (svc_1) down
- release-image artifact (art_0) absent
- db-migration artifact (art_1) absent
- maintenance_window_open flag (flag_0) off (false)
- secrets_synced flag (flag_1) off (false)

Goal: service billing-0 must be at least healthy.

To get healthy we need to go through states: down -> provisioned -> configured -> deployed -> healthy.

Provision uses advance_0 (provision): requires service down.

Configure uses advance_1 (configure): requires service provisioned.

Deploy uses advance_2 (deploy): requires service configured.

Health-check uses advance_3 (health-check): requires service deployed AND flag_0 set AND art_0 artifact published.

Thus before health-check we need to have flag_0 set (true) and art_0 published.

Also note there's also maybe other steps like building artifact etc.

So we need to:

- Provision svc_0 (advance_0 with service=svc_0)
- Configure svc_0 (advance_1)
- Deploy svc_0 (advance_2)
- Meanwhile we need to handle artifacts: build art_0 (build_art_0) then publish (publish_art_0)
- Also set flag_0 (set_flag_0)
Then health-check svc_0 (advance_3).

Potentially we could do some steps out of order as long as preconditions satisfied.

Check each precondition:

- advance_0: service must be down. Initially svc_0 down => ok.

After advance_0, svc_0 becomes provisioned.

- advance_1: service must be provisioned. After provisioning, yes.

- advance_2: service must be configured. After configure, yes.

Now artifact flow:

- build_art_0: artifact must be absent. Initially art_0 absent => ok. After built.

- publish_art_0: artifact must be built. After build, yes.

Set flag: set_flag_0: flag must be false initially. Yes.

Now health-check: service must be deployed (we will have done that after advance_2). Need flag_0 set (true) and art_0 artifact published.

Thus ordering: We can interleave but ensure by time of health-check all three conditions satisfied.

One possible sequence:

1. advance_0 (provision svc_0)
2. advance_1 (configure svc_0)
3. advance_2 (deploy svc_0)
   At this point svc_0 deployed.

But we still need artifact built/published and flag set. Could do those before or after deploy? Health-check requires deployed, so we need deploy before health-check. But we could also do artifact steps before deploy; they don't depend on service state. So we can do them earlier.

Let's design:

- build_art_0
- publish_art_0
- set_flag_0
- advance_0 (provision svc_0)
- advance_1 (configure svc_0)
- advance_2 (deploy svc_0)
- advance_3 (health-check svc_0)

Check preconditions each step:

Start: svc_0 down, art_0 absent, flag_0 false.

Step1 build_art_0: artifact absent => ok. After: art_0 built.

Step2 publish_art_0: artifact built => ok. After: art_0 published.

Step3 set_flag_0: flag false => ok. After: flag_0 true.

Step4 advance_0: svc_0 down => ok. After: svc_0 provisioned.

Step5 advance_1: svc_0 provisioned => ok. After: svc_0 configured.

Step6 advance_2: svc_0 configured => ok. After: svc_0 deployed.

Step7 advance_3: svc_0 deployed, flag_0 true, art_0 published => ok. After: svc_0 healthy.

Goal achieved.

All within 7 tool calls (<14). No need to involve registry-1 or db-migration artifact or flag_1.

Thus output JSON array with objects: {"tool":"build_art_0","args":{"artifact":"art_0"}}, etc.

Need to use exact tool IDs as given: build_art_0, publish_art_0, set_flag_0, advance_0, advance_1, advance_2, advance_3.

Make sure args keys match param names: For build_artifact param: artifact: artifact. So args: {"artifact":"art_0"}.

Similarly publish_artifact: {"artifact":"art_0"}.

set_flag: {"flag":"flag_0"}.

advance (provision): {"service":"svc_0"}.

advance (configure): {"service":"svc_0"}.

advance (deploy): {"service":"svc_0"}.

advance (health-check): {"service":"svc_0"}.

Return JSON array.

No extra text.
