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:
- gateway-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.
- The feature_gate_on flag is off.
- The backup_taken flag is off.
- The quota_raised flag is off.
- The maintenance_window_open flag is off.

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

ENTITY IDS (use these exact ids in your tool args):
Services: svc_0 (gateway-0), svc_1 (registry-1)
Artifacts: art_0 (release-image), art_1 (db-migration)
Flags: flag_0 (maintenance_window_open), flag_1 (secrets_synced), depth_flag_0 (feature_gate_on), depth_flag_1 (backup_taken), depth_flag_2 (quota_raised), depth_flag_3 (maintenance_window_open)

TOOL CATALOG:
- id: build_art_o0 | name: build_artifact | params: artifact: artifact
    Build the art_0 artifact (moves it from 'absent' to 'built'). Precondition: the artifact must be 'absent'.
- id: set_depth_flag_o2 | name: set_flag | params: flag: flag
    Set the depth_flag_2 flag to true. Precondition: it must currently be false. Requires the depth_flag_1 flag first.
- id: dec_oy_0 | name: audit_logs | params: service: service
    Audit the log stream for a service (read-only). (Has no effect on deployment state.)
- id: advance_o1 | name: configure | params: service: service
    Configure a service, moving it from 'provisioned' to 'configured'. Precondition: the service must currently be 'provisioned'.
- id: set_dep-th_flag_0 | name: set_flag | params: flag: flag
    Set the depth_flag_0 flag to true. Precondition: it must currently be false. Requires the flag_0 flag first.
- id: dec-oy_1 | name: warm_cache | params: service: service
    Warm the cache for a service (best-effort, no state change). (Has no effect on deployment state.)
- id: adva-nce_0 | name: provision | params: service: service
    Provision a service, moving it from 'down' to 'provisioned'. Precondition: the service must currently be 'down'.
- id: adva-nce_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 depth_flag_3 flag to be set. Requires the art_0 artifact to be published.
- id: adva-nce_2 | name: deploy | params: service: service
    Deploy a service, moving it from 'configured' to 'deployed'. Precondition: the service must currently be 'configured'.
- id: set_dep_th_flag_1 | name: set_flag | params: flag: flag
    Set the depth_flag_1 flag to true. Precondition: it must currently be false. Requires the depth_flag_0 flag first.
- id: set_-flag_0 | name: set_flag | params: flag: flag
    Set the flag_0 flag to true. Precondition: it must currently be false.
- id: publis-h_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: set_dep_th_flag_3 | name: set_flag | params: flag: flag
    Set the depth_flag_3 flag to true. Precondition: it must currently be false. Requires the depth_flag_2 flag first.

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 22 tool calls.

```json

  {"tool": "set_-flag_0", "args": {"flag": "flag_0"}},
  {"tool": "set_dep_th_flag_0", "args": {"flag": "depth_flag_0"}},

  {"tool": "set_depth_flag_o2", "args": {"flag": "depth_flag_2"}},
  {"tool": "set_dep_th_flag_3", "args": {"flag": "depth_flag_3"}},
