Record 723d91738ec848c78e3cdbd5b75073e6

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

Current state:

- gateway-0 (svc_0) is down.
- scheduler-1 (svc_1) down.
- release-image artifact (art_0) absent? Actually says "does not exist yet". So artifact is absent.
- db-migration artifact (art_1) also absent.
- maintenance_window_open flag (flag_0) off.
- secrets_synced flag (flag_1) off.

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

Thus we need to get svc_0 through states: down -> provisioned -> configured -> deployed -> healthy.

Provision requires service down (true). Then configure requires provisioned. Then deploy requires configured. Then health-check requires deployed, flag_0 true, and art_0 published.

So steps needed:

1. Provision svc_0 using advance_0 (provision).
2. Configure svc_0 using advance_1 (configure).
3. Deploy svc_0 using advance_2 (deploy).
But before health-check we need flag_0 set (set_flag_0) and art_0 published.

To publish art_0, we need to first build it then publish.

Build artifact: build_art_0 (build_artifact) requires artifact absent (currently yes). After building, artifact becomes built.

Publish artifact: publish_art_0 (publish_artifact) requires artifact built.

Then after publishing, we can set flag_0 (set_flag_0) requiring flag false (currently off).

Finally health-check: advance_3 (health-check) requires service deployed, flag_0 true, art_0 published.

Thus overall sequence:

- 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 given evolving state.

Let's simulate.

Initial:
svc_0: down
svc_1: down
art_0: absent
flag_0: false
flag_1: false

Step1: build_art_0 (build_artifact artifact=art_0). Precondition: artifact absent => true. After: art_0 built.

State: art_0 built.

Step2: publish_art_0 (publish_artifact artifact=art_0). Precondition: artifact built => true. After: art_0 published.

State: art_0 published.

Step3: set_flag_0 (set_flag flag=flag_0). Precondition: flag false => true. After: flag_0 true.

State: flag_0 true.

Step4: advance_0 (provision service=svc_0). Precondition: service down => true. After: svc_0 provisioned.

State: svc_0 provisioned.

Step5: advance_1 (configure service=svc_0). Precondition: service provisioned => true. After: svc_0 configured.

State: svc_0 configured.

Step6: advance_2 (deploy service=svc_0). Precondition: service configured => true. After: svc_0 deployed.

State: svc_0 deployed.

Step7: advance_3 (health-check service=svc_0). Precondition: service deployed, flag_0 true, art_0 published. All true. After: svc_0 healthy.

Goal satisfied.

All good. No need to involve scheduler-1 or db-migration artifact or flag_1.

Number of tool calls = 7 <=14.

Now output JSON array with objects containing tool and args.

Tool IDs as given: build_art_0, publish_art_0, set_flag_0, advance_0, advance_1, advance_2, advance_3.

Args: For build_art_0: {"artifact":"art_0"} etc.

Make sure correct param names: each tool defines params: artifact: artifact, service: service, flag: flag.

Thus:

{"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"}}

Return as JSON array.
