+"""World calendar + trigger firing helpers.
+
+Triggers fire on changes to in-world time (NOT real-time polling). When the
+orchestrator advances world time (via the `advance_time` tool or the
+`time_advance` field in a plan), the engine checks all unfired triggers for
+that session and fires any whose `fire_at` is now <= the new world time.
+
+Each world may define its own calendar via `world.definition.calendar`:
+  {
+    "hours_per_day": 24,        # default 24
+    "days_per_week": 7,         # informational only (not used in math)
+    "minutes_per_hour": 60      # default 60
+  }
+
+World time is stored as a string "day_{D}_hour_{H}" (we don't track minutes
+in the string to keep it compact — minutes are tracked separately in
+world.state.world_time if needed).
+
+The trigger's `fire_at` is also a "day_D_hour_H" string. We compare by
+totaling the in-world minutes since day-0-hour-0 for each side.

+"""Game orchestrator: runs the multi-step LLM tool-calling loop and produces a narrative step.
+
+Design (v2 — tool-calling-first):
+  - The orchestrator LLM is given a set of game tools (dice_roll, update_state,
+    rag_query, rag_add, schedule_trigger, advance_time, run_subagent) PLUS a
+    `submit_plan` tool. The LLM calls game tools to execute its plan, then
+    calls `submit_plan` to terminate the loop with structured data.
+  - The step-writer LLM is given only a `submit_scene` tool. It calls this
+    to return the narrative + options; its text response is ignored.
+  - This replaces the old "return JSON in your text response" pattern which
+    conflicted with tool use and caused the model to dump raw JSON into chat.
