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

Goal: service 'cache-0' (svc_0) must be at least healthy.

Current state:

- cache-0 is down (not yet provisioned). So we need to go through states: down -> provisioned -> configured -> deployed -> healthy.

Provision uses advance_0 (name: provision) with precondition service must be down.

Configure uses advance_1 (name: configure) precondition service must be provisioned.

Deploy uses advance_2 (name: deploy) precondition service must be configured.

Health-check uses advance_3 (name: health-check) precondition service must be deployed AND requires depth_flag_1 flag set AND requires art_0 artifact to be published.

Thus before health-check we need depth_flag_1 true, which depends on depth_flag_0 true via set_depth_flag_1 requiring depth_flag_0 first. And depth_flag_0 requires flag_0 (maintenance_window_open) first? Actually description: set_depth_flag_0 sets depth_flag_0 flag to true, precondition: it must currently be false. Requires the flag_0 flag first. Means we need flag_0 already true before setting depth_flag_0.

Similarly set_depth_flag_1 requires depth_flag_0 flag first.

So steps:

Set flag_0 (maintenance_window_open) using set_flag_0 (id: set_flag_0).

Then set depth_flag_0 using set_depth_flag_0 (id: set_depth_flag_0).

Then set depth_flag_1 using set_depth_flag_1 (id: set_depth_flag_1).

Now also need art_0 artifact published. Artifact initially absent. Need to build then publish.

Build artifact art_0: build_art_0 (id: build_art_0) precondition artifact absent.

Publish artifact art_0: publish_art_0 (id: publish_art_0) precondition artifact built.

Now after those, we can do health-check on svc_0.

But we also need to get svc_0 to deployed state before health-check.

Sequence:

Start: svc_0 down.

1. advance_0 (provision) svc_0 => provisioned.

2. advance_1 (configure) svc_0 => configured.

3. advance_2 (deploy) svc_0 => deployed.

4. Then health-check (advance_3) svc_0 => healthy, but only if depth_flag_1 true and art_0 published.

Thus we need to ensure flags and artifact done before health-check. They can be done earlier or interleaved as long as preconditions satisfied.

Check each tool's preconditions:

- advance_0: service down. Initially down, ok.

- advance_1: service provisioned. After step1 ok.

- advance_2: service configured. After step2 ok.

- set_flag_0: flag_0 false initially. Ok.

- set_depth_flag_0: depth_flag_0 false initially, requires flag_0 true. So after set_flag_0.

- set_depth_flag_1: depth_flag_1 false initially, requires depth_flag_0 true. So after set_depth_flag_0.

- build_art_0: artifact absent initially. Ok.

- publish_art_0: artifact built after build_art_0.

- advance_3: health-check: service deployed, depth_flag_1 true, art_0 published.

Thus we need to have all those preconditions satisfied before calling advance_3.

Potential ordering: We could do provision/configure/deploy first, then flags and artifact, then health-check. Or intermix.

Let's propose:

[
 {"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":"set_depth_flag_0","args":{"flag":"depth_flag_0"}},
 {"tool":"set_depth_flag_1","args":{"flag":"depth_flag_1"}},
 {"tool":"build_art_0","args":{"artifact":"art_0"}},
 {"tool":"publish_art_0","args":{"artifact":"art_0"}},
 {"tool":"advance_3","args":{"service":"svc_0"}}
]

That's 9 calls, within limit.

Check preconditions at each point:

After advance_0: svc_0 provisioned.

After advance_1: svc_0 configured.

After advance_2: svc_0 deployed.

After set_flag_0: flag_0 true.

After set_depth_flag_0: depth_flag_0 true (requires flag_0 true, ok).

After set_depth_flag_1: depth_flag_1 true (requires depth_flag_0 true, ok).

After build_art_0: art_0 built.

After publish_art_0: art_0 published.

Now advance_3: service deployed true, depth_flag_1 true, art_0 published true. All good.

Thus final state: svc_0 healthy.

Goal satisfied.

We should output JSON array exactly as specified.
