We need to produce a JSON array of tool calls that achieve the goal: service 'registry-0' must reach at least the 'deployed' state. Entity IDs: services svc_0 (registry-0), svc_1 (ledger-1). Artifacts: 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 provisioned). So service svc_0 is down.
- ledger-1 is down (not provisioned). So svc_1 is down.
- release-image artifact does not exist yet (absent).
- db-migration artifact does not exist yet (absent).
- maintenance_window_open flag is off (false).
- secrets_synced flag is off (false).

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

We have tools:

- build_art_0: build artifact art_0 (moves from absent to built). Precondition: artifact must be absent. So we can build it.

- decoy_0: audit logs (no effect).

- advance_0: provision a service (down -> provisioned). Precondition: service must be down. So we can provision svc_0.

- decoy_1: warm_cache (no effect).

- set_flag_0: set flag_0 to true. Precondition: currently false. So we can set it.

- advance_2: deploy a service (configured -> deployed). Precondition: service must be configured, flag_0 must be true, and art_0 must be published.

- advance_1: configure a service (provisioned -> configured). Precondition: service must be provisioned.

- publish_art_0: publish artifact (built -> published). Precondition: artifact must be built.

We need to get svc_0 to deployed. Path: down -> provisioned -> configured -> deployed.

Steps needed:

1. Build artifact art_0 (release-image). Currently absent, so we can build it. Use build_art_0 with artifact: art_0.

2. Publish artifact art_0 (move built to published). Precondition: artifact must be built. After step 1, it's built. So we can publish_art_0 with artifact: art_0.

3. Set flag_0 (maintenance_window_open) to true. Currently false, so we can set_flag_0 with flag: flag_0.

4. Provision service svc_0 (down -> provisioned). Precondition: service must be down. It is down, so we can advance_0 with service: svc_0.

5. Configure service svc_0 (provisioned -> configured). Precondition: service must be provisioned. After step 4, it's provisioned, so we can advance_1 with service: svc_0.

6. Deploy service svc_0 (configured -> deployed). Precondition: service must be configured, flag_0 true, and art_0 published. After steps 2 and 3, those are satisfied. So we can advance_2 with service: svc_0.

Thus we need at least 6 tool calls: build_art_0, publish_art_0, set_flag_0, advance_0, advance_1, advance_2.

Check preconditions:

- build_art_0: artifact must be absent. It is absent. OK.

- publish_art_0: artifact must be built. After build, it's built. OK.

- set_flag_0: flag must be false. It is false. OK.

- advance_0: service must be down. It is down. OK.

- advance_1: service must be provisioned. After advance_0, it's provisioned. OK.

- advance_2: service must be configured, flag_0 true, artifact published. After advance_1, it's configured. flag_0 is true after set_flag_0. artifact published after publish_art_0. So all satisfied.

Thus a valid plan exists.

We must output JSON array of objects with "tool": "<tool id>", "args": {...}. Use exact tool IDs: build_art_0, publish_art_0, set_flag_0, advance_0, advance_1, advance_2.

Parameter names: For build_art_0, param is "artifact". So args: {"artifact":"art_0"}.

For publish_art_0, param is "artifact". So args: {"artifact":"art_0"}.

For set_flag_0, param is "flag". So args: {"flag":"flag_0"}.

For advance_0, param is "service". So args: {"service":"svc_0"}.

For advance_1, param is "service". So args: {"service":"svc_0"}.

For advance_2, param is "service". So args: {"service":"svc_0"}.

Order must be from current state, so sequence as above.

Thus JSON array:

[
  {"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"}}
]

Check that we didn't exceed 12 calls; we have 6.

Make sure no extra whitespace? It's fine.

Return only JSON array, no extra text.

Thus final answer.
