We need to plan steps to get billing-0 to healthy. Entities: svc_0 (billing-0). Need to provision, configure, deploy, health-check. Preconditions: service can only be configured once provisioned; can only be deployed once configured; can only be health-checked once deployed. Also health-check requires flag_0 set and art_0 published. Also need artifact art_0 built and published before health-check. Also need flag_0 set (maintenance_window_open). Also need to ensure flags preconditions: flag can only be set while currently false; some flags require another flag to already be set first. Here flag_0 (maintenance_window_open) maybe independent? Not mentioned requiring other flag. So we can set flag_0 directly (must be false currently). Also need to build artifact art_0 (db-migration? Wait artifact list: art_0 is release-image, art_1 is db-migration. The goal mentions service billing-0 must reach healthy. Health-check requires art_0 artifact published. That's release-image artifact. So we need to build art_0, then publish_artifact (publish_art_0). Also need to set_flag_0 (maintenance_window_open). Also need to provision svc_0, configure svc_0, deploy svc_0, then health-check svc_0.

We have constraints: no one has built db-migration artifact this cycle, but we don't need db-migration for billing-0. However we might need to ensure we don't break anything else? Not needed.

Current state: No one has built release-image artifact this cycle (art_0). So it's absent. Also no one has built db-migration (art_1). So both absent. flags: secrets_synced flag never enabled after reset (flag_1 false). maintenance_window_open flag never enabled (flag_0 false). So we can set flag_0.

We also have service svc_0 fully torn down and not touched since last week. So its state is down? It says fully torn down, so likely state is down (not provisioned). So we need to provision it first.

We have at most 7 tool calls. Let's outline steps:

1. set_flag_0 (set_flag_0 flag: flag_0) -> sets maintenance_window_open to true. Precondition: flag currently false, which holds. No other precondition.

2. build_art_0 (build_artifact artifact: art_0) -> builds release-image.

3. publish_art_0 (publish_artifact artifact: art_0) -> publishes it.

Now we can provision svc_0: advance_0 provision service svc_0.

Then configure svc_0: advance_1 configure service svc_0.

Then deploy svc_0: advance_2 deploy service svc_0.

Then health-check svc_0: advance_3 health-check service svc_0. This requires flag_0 set (true) and art_0 published (yes). So preconditions satisfied.

We need to ensure we don't exceed 7 calls. So far we have 1 (set_flag_0) + 1 (build_art_0) + 1 (publish_art_0) + 1 (provision) + 1 (configure) + 1 (deploy) + 1 (health-check) = 7 calls exactly. That's allowed.

Check any other preconditions: health-check also requires flag_0 set (we set it). Also requires art_0 published (we publish). Good.

Also need to ensure we don't need to set any other flags? No.

We also might need to ensure that we don't need to set flag_1? Not required.

Thus the plan is straightforward.

Now produce JSON array of tool calls in order.

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

Arguments:

- set_flag_0: {"flag":"flag_0"}
- build_art_0: {"artifact":"art_0"}
- publish_art_0: {"artifact":"art_0"}
- advance_0: {"service":"svc_0"}
- advance_1: {"service":"svc_0"}
- advance_2: {"service":"svc_0"}
- advance_3: {"service":"svc_0"}

Make sure JSON array format: each element object with "tool": "<id>", "args": { ... }.

No extra whitespace? It's okay.

Return just JSON array.

Let's craft:

[
  {"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_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"}}
]

Check that tool IDs match catalog: set_flag_0 is id: set_flag_0? Actually catalog says id: set_flag_0 | name: set_flag | params: flag: flag. So tool id is set_flag_0. Good.

build_art_0 id: build_art_0. publish_art_0 id: publish_art_0. advance_0 id: advance_0. advance_1 id: advance_1. advance_2 id: advance_2. advance_3 id: advance_3.

All good.

Now output exactly that JSON array, no extra text.
