Record 294f188ce9ba4b29ae9e4671e157d706

We need to plan steps to get ledger-0 to deployed state. Entities: svc_0 (ledger-0), svc_1 (registry-1). Artifacts: art_0 (release-image), art_1 (db-migration). Flags: flag_0 (maintenance_window_open), flag_1 (secrets_synced). Current state: ledger-0 is down (not provisioned). registry-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 'ledger-0' must reach at least the 'deployed' state.

We have tools:

- publish_art_0 (publish_artifact): publishes art_0 (moves from built to published). Precondition: artifact must be built.

- set_flag_0 (set_flag): set flag_0 to true. Precondition: currently false.

- advance_2 (deploy): deploy a service, moving from configured to deployed. Precondition: service currently configured; requires flag_0 true; requires art_0 published.

- advance_1 (configure): configure a service, moving from provisioned to configured. Precondition: service currently provisioned.

- decoy_0 (audit_logs): no effect.

- build_art_0 (build_artifact): build artifact, moves from absent to built. Precondition: artifact must be absent.

- advance_0 (provision): provision a service, moving from down to provisioned. Precondition: service currently down.

- decoy_1 (warm_cache): no effect.

We can use at most 12 calls.

We need to get ledger-0 to deployed. To deploy, we need it to be configured first, then deploy. To configure, need it provisioned. To provision, need it down (which it is). So we can provision it.

But also need flag_0 true and art_0 published for deploy. So we need to set flag_0 true (currently off). Also need to build and publish art_0. But art_0 must be built first (build_artifact). Then publish_artifact.

Thus sequence:

1. build_art_0 artifact=art_0 (build release-image). Precondition: artifact must be absent. It is absent, so ok.

2. publish_art_0 artifact=art_0 (publish). Precondition: artifact must be built. After step1 it's built, so ok.

3. set_flag_0 flag=flag_0 (set maintenance_window_open to true). Precondition: currently false. It's off, so ok.

Now we need to provision ledger-0 (svc_0). It's currently down. Use advance_0 (provision) service=svc_0. Precondition: service must be down. It is down, so ok.

Now it becomes provisioned.

Then configure svc_0: advance_1 (configure) service=svc_0. Precondition: service must be provisioned. It is now provisioned, so ok. Moves to configured.

Then deploy svc_0: advance_2 (deploy) service=svc_0. Precondition: service must be configured; requires flag_0 true; requires art_0 published. All satisfied. So it moves to deployed.

Thus we have 6 tool calls: build_art_0, publish_art_0, set_flag_0, advance_0, advance_1, advance_2.

Check any other constraints: The db-migration artifact not needed? Not required for ledger-0 deployment. But maybe needed for other services? Not needed for goal. So we can ignore.

We must ensure we use exact entity IDs: service svc_0 for ledger-0. artifact art_0 for release-image. flag_0 for maintenance_window_open.

Tool IDs: build_art_0 is "build_art_0"? Actually catalog says id: build_art_0 | name: build_artifact | params: artifact: artifact. So tool id is "build_art_0". Similarly publish_art_0 id: publish_art_0. set_flag_0 id: set_flag_0. advance_0 id: advance_0. advance_1 id: advance_1. advance_2 id: advance_2.

Thus JSON array of objects with "tool": "<id>", "args": {...}. Parameter names: artifact, service, flag. According to catalog: publish_artifact params: artifact: artifact. So args: {"artifact":"art_0"}.

set_flag params: flag: flag. So args: {"flag":"flag_0"}.

deploy params: service: service. So args: {"service":"svc_0"}.

configure params: service: service. So args: {"service":"svc_0"}.

provision params: service: service. So args: {"service":"svc_0"}.

Thus sequence:

1. {"tool":"build_art_0","args":{"artifact":"art_0"}}
2. {"tool":"publish_art_0","args":{"artifact":"art_0"}}
3. {"tool":"set_flag_0","args":{"flag":"flag_0"}}
4. {"tool":"advance_0","args":{"service":"svc_0"}}
5. {"tool":"advance_1","args":{"service":"svc_0"}}
6. {"tool":"advance_2","args":{"service":"svc_0"}}

Check precondition for advance_2: requires flag_0 true (we set it) and art_0 published (we published). Good.

Thus goal satisfied. Output JSON array exactly.

Make sure no extra whitespace? Probably fine.

Thus final answer: JSON array of 6 objects.
