You are an operations planner. Below is the current state of a small deployment environment, a goal, and a catalog of tools you may call. Each tool has typed parameters and PRECONDITIONS that must hold at the moment you call it; calling a tool whose preconditions are not met is an error and your plan fails.
CURRENT STATE:
- billing-0 is currently down (not yet provisioned).
- registry-1 is currently down (not yet provisioned).
- The release-image artifact does not exist yet.
- The db-migration artifact does not exist yet.
- The maintenance_window_open flag is off.
- The secrets_synced flag is off.

GOAL (all conditions must hold at the end):
- service 'billing-0' must reach at least the 'healthy' state

ENTITY IDS (use these exact ids in your tool args):
Services: svc_0 (billing-0), svc_1 (registry-1)
Artifacts: art_0 (release-image), art_1 (db-migration)
Flags: flag_0 (maintenance_window_open), flag_1 (secrets_synced)

TOOL CATALOG:
- id: advance_2 | name: deploy | params: service: service
    Deploy a service, moving it from 'configured' to 'deployed'. Precondition: the service must currently be 'configured'.
- id: advance_1 | name: configure | params: service: service
    Configure a service, moving it from 'provisioned' to 'configured'. Precondition: the service must currently be 'provisioned'.
- id: build_art_0 | name: build_artifact | params: artifact: artifact
    Build the art_0 artifact (moves it from 'absent' to 'built'). Precondition: the artifact must be 'absent'.
- id: advance_3 | name: health-check | params: service: service
    Health-check a service, moving it from 'deployed' to 'healthy'. Precondition: the service must currently be 'deployed'. Requires the flag_0 flag to be set. Requires the art_0 artifact to be published.
- id: decoy_0 | name: audit_logs | params: service: service
    Audit the log stream for a service (read-only). (Has no effect on deployment state.)
- id: set_flag_0 | name: set_flag | params: flag: flag
    Set the flag_0 flag to true. Precondition: it must currently be false.
- id: publish_art_0 | name: publish_artifact | params: artifact: artifact
    Publish the art_0 artifact (moves it from 'built' to 'published'). Precondition: the artifact must be 'built'.
- id: advance_0 | name: provision | params: service: service
    Provision a service, moving it from 'down' to 'provisioned'. Precondition: the service must currently be 'down'.
- id: decoy_1 | name: warm_cache | params: service: service
    Warm the cache for a service (best-effort, no state change). (Has no effect on deployment state.)

Output ONLY a JSON array of tool calls that, executed in order from the current state, satisfies the goal. Each element must be an object {"tool": "<tool id>", "args": {"<param>": "<entity id>", ...}}. Do not include any prose, explanation, or markdown fences -- just the JSON array.

You may use at most 14 tool calls.
