Ultra reads the prompt, this answer, the verified correct answer and the difficulty settings, then explains the mistake. The verifier's own classification is shown next to it for comparison.

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:
- cache-0 is currently down (not yet provisioned).
- gateway-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 'cache-0' must reach at least the 'deployed' state

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

TOOL CATALOG:
- 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: set_flag_0 | name: set_flag | params: flag: flag
    Set the flag_0 flag to true. Precondition: it must currently be false.
- 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: decoy_0 | name: audit_logs | params: service: service
    Audit the log stream for a service (read-only). (Has no effect on deployment state.)
- id: advance_2 | name: deploy | params: service: service
    Deploy a service, moving it from 'configured' to 'deployed'. Precondition: the service must currently be 'configured'. Requires the flag_0 flag to be set. Requires the art_0 artifact to be published.
- 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: 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 12 tool calls.

IMPORTANT: it is possible that the goal CANNOT be achieved with the tools in this catalog. Decide for yourself whether a valid plan exists. If one does, output it. If no sequence of the available tools can satisfy the goal, output exactly [] (an empty JSON array) instead. Do not invent tools that are not listed, and do not output a partial or best-effort plan that fails to reach the goal -- an empty array is the correct answer in that case.
