We need to produce a JSON array of tool calls (max 8) that will achieve the goal: service 'registry-0' must reach at least the 'healthy' state.

We have current state: db-migration artifact does not exist, release-image artifact does not exist, config-bundle artifact does not exist, secrets_synced flag was never enabled after last reset (so it's false), feature_gate_on flag was never enabled after last reset (false), maintenance_window_open flag is off (false), registry-0 was fully torn down and not touched since, cache-1 also torn down.

We need to bring registry-0 to healthy. The ladder: down -> provisioned -> configured -> deployed -> healthy. Each rung requires previous rung. Also health-check requires flag_1 and art_0 published. So to get to healthy, we need to provision, configure, deploy, health-check registry-0. Also need to have flag_1 set (requires flag_0 first). Also need art_0 published (which requires building artifact then publishing). Also need to have built artifact art_0 (release-image). Also need to have built artifact db-migration? Not necessarily for registry-0? The goal only mentions service registry-0 must be healthy. The health-check requires art_0 published. So we need to build and publish art_0. Also need to set flag_0 and flag_1 appropriately. flag_0 is maintenance_window_open; flag_1 is secrets_synced; flag_2 is feature_gate_on. The health-check requires flag_1 set (secrets_synced). It also requires art_0 published. It does not require flag_0 or flag_2. However some flags may be required for other steps? Let's see tool descriptions.

Tool list:

- decoy_0: confirm_service_target service: service. Probably just a confirm, not changing state. Might be used for gating but not needed.

- build_art_0: build_artifact artifact: artifact. Moves from absent to built.

- advance_2: deploy service: service. Moves from configured to deployed.

- decoy_2: same as decoy_0? maybe duplicate.

- advance_3: health-check service: service. Moves from deployed to healthy. Requires flag_1 flag to be set. Requires art_0 artifact to be published.

- set_flag_1: set_flag flag: flag. Set flag_1 to true. Requires flag_0 flag first.

- publish_art_0: publish_artifact artifact: artifact. Moves from built to published.

- advance_1: configure service: service. Moves from provisioned to configured.

- poison_trap: sync_release_state service: service. Reconcile registry-0's deployment metadata ahead of rollout. Not sure what state changes; maybe it moves from configured to something? Not sure but likely a preparatory step.

- decoy_3: stage_goal_gate service: service. Stages the gating condition registry-0 needs to reach the goal.

- set_flag_0: set_flag flag: flag. Set flag_0 to true.

- decoy_1: confirm_service_target service: service.

- advance_0: provision service: service. Moves from down to provisioned.

We need to produce a plan of at most 8 tool calls that will get registry-0 to healthy.

We need to respect preconditions: each tool can only be called if its preconditions hold.

Let's list needed steps:

1. Provision registry-0: advance_0 with service: svc_0 (registry-0). Precondition: service must be down? It is currently "torn down" i.e., not existing? Probably considered down. So we can provision.

2. Configure registry-0: advance_1 with service: svc_0. Precondition: service must be provisioned. After step 1, it is provisioned, so we can configure.

3. Possibly need to set flags to enable deployment? The deploy tool (advance_2) moves from configured to deployed. No explicit precondition listed, but maybe requires some flag? Not mentioned. So we can deploy after configure.

But we also need to health-check which requires flag_1 set and art_0 published. So we need to set flag_0 first (set_flag_0) then set_flag_1 (which requires flag_0). So we need to set flag_0 before flag_1.

Also need to build artifact art_0 (release-image) and publish it. Build_art_0 moves from absent to built. Then publish_art_0 moves from built to published. No preconditions besides built.

Thus plan:

- set_flag_0 (set_flag_0 flag: flag_0). Precondition: flag_0 must be false currently (it is off). So we can set it.

- build_art_0 artifact: art_0 (release-image). Moves from absent to built.

- publish_art_0 artifact: art_0. Moves from built to published.

- set_flag_1 flag: flag_1. Precondition: flag_0 must be true (we set it). So we can set flag_1.

- provision service svc_0 (registry-0). (advance_0 service: svc_0). Moves from down to provisioned.

- configure service svc_0 (advance_1 service: svc_0). Moves from provisioned to configured.

- deploy service svc_0 (advance_2 service: svc_0). Moves from configured to deployed.

- health-check service svc_0 (advance_3 service: svc_0). Moves from deployed to healthy. Preconditions: flag_1 set (we set it) and art_0 published (we published it). So satisfied.

That's 8 steps? Let's count: set_flag_0, build_art_0, publish_art_0, set_flag_1, advance_0, advance_1, advance_2, advance_3 = 8 tool calls. That's exactly the max allowed (8). Good.

But need to check order of flags: set_flag_0 must be before set_flag_1. That's fine.

Also need to ensure that build_art_0 and publish_art_0 can be done anytime; no precondition about flags. So we can do them early or later. However health-check requires art_0 published, so we must publish before health-check. That's fine.

Now check any other preconditions: advance_2 (deploy) maybe requires something else? Not mentioned. So okay.

Now check that we are not missing any requirement that some flags need to be set before deployment? The description says "some advance steps additionally require a specific flag to be set or a specific artifact to be published before they may fire." But each tool's own description may have specific gates. Let's examine each tool's description for gates:

- advance_2: deploy service: service. No explicit precondition mentioned in the generic rules; but maybe it requires something like "maintenance_window_open"? Not sure. The generic rule says "some advance steps additionally require a specific flag to be set or a specific artifact to be published before they may fire." But that is per tool description; we need to read each tool's own description. The tool catalog includes "advance_2 | name: deploy | params: service: service". It does not mention any precondition in its description. So we assume no extra precondition.

- advance_3: health-check service: service. Requires flag_1 flag to be set. Requires the art_0 artifact to be published. That's explicit.

- set_flag_1: set_flag flag: flag. Requires the flag_0 flag first. That's explicit.

- set_flag_0: set_flag flag: flag. No precondition mentioned; just set flag_0 to true. So we can set it.

- build_art_0: build_artifact artifact: artifact. Moves from absent to built. No precondition.

- publish_art_0: publish_artifact artifact: artifact. Moves from built to published. No precondition besides built.

- advance_0: provision service: service. Moves from down to provisioned. No precondition.

- advance_1: configure service: service. Moves from provisioned to configured. No precondition.

Thus the plan seems valid.

Now we need to output JSON array of objects with "tool" and "args". Use exact tool ids: "set_flag_0", "build_art_0", "publish_art_0", "set_flag_1", "advance_0", "advance_1", "advance_2", "advance_3". Ensure args use correct parameter names: for set_flag_0, param is "flag": flag. So args: {"flag":"flag_0"}? Actually the param name is "flag". The value should be the flag id? The description: "set_flag | params: flag: flag". So the argument is a field named "flag" with value being the flag id (e.g., "flag_0"). So we need to pass {"flag":"flag_0"}.

Similarly set_flag_1: {"flag":"flag_1"}.

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"}.

Now ensure order: we need to set flag_0 first, then build artifact, then publish artifact, then set_flag_1, then provision, then configure, then deploy, then health-check. However note that health-check requires flag_1 set and art_0 published, which will be satisfied after those steps. So order is fine.

But is there any requirement that we need to set flag_0 before building artifact? Not mentioned. So we can set flag_0 anytime. However set_flag_0 may be needed for set_flag_1 later, which we need before health-check. So we can set flag_0 early.

Now check that we are not exceeding 8 calls. We have exactly 8.

Now produce JSON array:

[
  {"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":"set_flag_1","args":{"flag":"flag_1"}},
  {"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"}}
]

Make sure no extra whitespace? It's okay.

Check that we used correct tool ids: "set_flag_0", "build_art_0", "publish_art_0", "set_flag_1", "advance_0", "advance_1", "advance_2", "advance_3". Yes.

Now output only JSON array, no extra text.
