We need to produce a JSON array of tool calls that achieve the goal: service 'registry-0' must reach at least 'deployed' state. Use exact entity IDs: service svc_0 (registry-0), svc_1 (ledger-1); artifact art_0 (release-image), art_1 (db-migration); flags flag_0 (maintenance_window_open), flag_1 (secrets_synced).

Current state: registry-0 is down (not yet provisioned). ledger-1 down. release-image artifact does not exist yet. db-migration artifact does not exist yet. maintenance_window_open flag is off. secrets_synced flag is off.

Goal: service 'registry-0' must reach at least 'deployed' state.

We have tools:

- advance_2 (deploy) : params service: service. Deploy a service, moving it from 'configured' to 'deployed'. Preconditions: service must currently be 'configured'. Requires flag_0 flag to be set. Requires art_0 artifact to be published.

- publish_art_0 (publish_artifact): artifact: artifact. Publish artifact (built -> published). Precondition: artifact must be 'built'.

- decoy_1 (warm_cache): service: service. No state change.

- advance_0 (provision): service: service. Provision a service, moving it from 'down' to 'provisioned'. Precondition: service must currently be 'down'.

- set_flag_0 (set_flag): flag: flag. Set flag_0 flag to true. Precondition: it must currently be false.

- decoy_0 (audit_logs): service: service. No effect.

- build_art_0 (build_artifact): artifact: artifact. Build artifact (absent -> built). Precondition: artifact must be 'absent'.

We need to get registry-0 to 'deployed' state. To deploy, it must be 'configured' first, flag_0 must be true, and art_0 must be published.

We can provision the service (down -> provisioned). But we need to get to 'configured' state before deploying. There's no tool that moves from provisioned to configured. Possibly provision results in 'provisioned' state, but we need 'configured' to deploy. There is no explicit tool to configure a service. Maybe provisioning automatically makes it 'configured'? The description says "Provision a service, moving it from 'down' to 'provisioned'." So after provision, state is 'provisioned', not 'configured'. There's no tool to move from provisioned to configured. However maybe 'configured' is a state that is assumed after provision? Not clear. The deploy tool precondition: service must currently be 'configured'. So we need to get to 'configured' state. There is no tool that changes state to 'configured'. Maybe provisioning results in 'configured'? But description says provision moves from 'down' to 'provisioned'. So not 'configured'.

Maybe there is an implicit step: after provisioning, you can configure? Not listed. Could use decoy_1 or decoy_0 but they have no effect. So maybe we cannot reach 'configured' state, thus cannot deploy. But maybe the 'configured' state is the same as 'provisioned'? The description says "Deploy a service, moving it from 'configured' to 'deployed'." So the precondition is that the service must currently be 'configured'. It doesn't say that you cannot be in other states; maybe you can be in 'provisioned' and still be considered 'configured'? But likely they are distinct. However maybe the state machine is: down -> provisioned -> configured -> deployed. But only provision is defined. There is no configure tool. So maybe you can only provision, and then you can deploy directly from provisioned? But precondition says must be 'configured', so maybe you need to set a flag that makes it configured? Not listed.

Maybe the 'configured' state is assumed after provisioning? Could be a mistake. But we must follow the given precondition strictly: service must currently be 'configured'. Since we cannot achieve that state with any tool, the goal may be unattainable. However maybe we can use 'advance_2' deploy tool to move from 'configured' to 'deployed', but we could also use 'advance_2' to move from 'down' to 'deployed'? No, it's defined as moving from 'configured' to 'deployed'.

Thus maybe the only way is to first provision the service (down -> provisioned). Then maybe there is an implicit step that provision also sets it to 'configured'? But not indicated. Could we use 'decoy_1' or 'audit_logs' to change state? No.

Maybe we can use 'set_flag_0' to set flag_0 true, but that doesn't affect state.

Thus maybe the plan is impossible, so output empty array. But let's examine if we can achieve 'configured' via some other path. Could we publish artifact, build artifact, etc. But those are about artifacts, not service state.

Maybe the 'configured' state is synonymous with 'provisioned'? The description of advance_2 says "Deploy a service, moving it from 'configured' to 'deployed'." It doesn't say that you cannot be in other states; maybe you can be in 'provisioned' and still be considered 'configured' for the purpose of deployment? That seems contradictory.

But maybe the state machine is: down -> provisioned -> configured -> deployed. The only tool that moves from down to provisioned is advance_0. There is no tool to move from provisioned to configured. However maybe after provisioning, the service automatically becomes configured? The description didn't mention a separate configure step; maybe provisioning includes configuration. So after provision, the service state becomes 'configured'? But they said "moving it from 'down' to 'provisioned'." So maybe the state after provision is 'provisioned', not 'configured'. But maybe 'provisioned' is a superset that includes 'configured'? Not sure.

Given typical deployment pipelines, you provision a service (i.e., create infrastructure), then configure it (set config), then deploy (install). But they only have provision and deploy tools. Maybe they omitted a configure step, assuming that after provisioning you can directly deploy? But precondition says service must be 'configured'. Could be a mistake in problem statement, but we must assume the precondition must be met exactly.

Thus to satisfy precondition, we need to have service in 'configured' state. There's no tool to set it to configured. So maybe we can use 'advance_2' deploy tool to move from 'configured' to 'deployed', but we could also use 'advance_2' to move from 'down' to 'deployed' if we treat 'configured' as 'down'? No.

Thus likely the goal is unattainable, so output [].

But maybe we can achieve 'configured' by using 'decoy_1' or 'audit_logs' which have no effect, so can't.

Thus answer: empty array.

But let's double-check if we can maybe bypass the precondition by setting flag_0 and publishing artifact, then using deploy tool on service that is currently 'configured'? But it's not. So can't.

Thus output [].

But maybe there is a way: we could provision the service (down -> provisioned). Then maybe we can use 'advance_2' deploy tool with service: svc_0, but precondition requires service to be 'configured'. Maybe 'provisioned' is considered 'configured' for the purpose of this tool? The description says "moving it from 'configured' to 'deployed'." That implies the current state must be 'configured'. If it's 'provisioned', precondition fails. So can't.

Thus goal cannot be achieved.

Hence output [].

But the instruction says: "If no sequence of the available tools can satisfy the goal, output exactly [] (an empty JSON array) instead." So we output [].

Thus final answer: [].

Make sure it's just JSON array, no extra text.
