 /**
  * Hero-related state owned by the core reducer.
  *
  * ## Contract
  * Maintains the full roster plus the day-scoped list of heroes that arrived on the current day.
  *
  * ## Invariants
  * - Hero ids in [roster] are expected to be unique.
  * - [arrivalsToday] are expected to reference heroes present in [roster] (or to be added alongside roster updates).
  * - [arrivalsToday] is expected to be cleared when advancing to a new day before emitting day events.
  *
  * ## Determinism
  * Pure data container. Deterministic arrivals/roster growth require deterministic generation and id counters.
  *
  * @property roster Current full roster of heroes.
  * @property arrivalsToday Hero ids that arrived during the current day-index.

 /**
  * Hero entity used by the reducer for contract pickup and resolution.
  *
  * ## Contract
  * Represents a single hero with immutable identity ([id]) and mutable gameplay attributes (rank/class/traits/status).
  *
  * ## Invariants
  * - [id] is stable and unique within a roster.
  * - [historyCompleted] is a completed-missions counter (expected >= 0).
  * - Trait values are expected to be bounded (see [Traits]).
  * - [warnUntilDay] and [banUntilDay] are day indices (nullable, expected >= 0 when set).
  *
  * ## Fraud Status Derivation
  * The effective disciplinary status is derived from [warnUntilDay] and [banUntilDay]:
  * - If `dayIndex < banUntilDay` → BANNED (cannot take contracts)
  * - Else if `dayIndex < warnUntilDay` → WARNED (can take contracts, repeat offense → ban)
  * - Else → normal status (AVAILABLE or other)
  *
  * ## Determinism
  * Pure data container. Deterministic evolution requires deterministic reducer logic and RNG stream.
  *
  * @property id Stable hero identifier ([HeroId]).
  * @property name Human-readable hero name.
  * @property rank Current rank tier ([Rank]).
  * @property klass Current hero class ([HeroClass]).
  * @property traits Personality/behavior traits influencing decisions.
  * @property status Current availability/mission status ([HeroStatus]).
  * @property historyCompleted Completed mission count (>= 0).
  * @property warnUntilDay Day index until which WARN is active (null = no warn).
  * @property banUntilDay Day index until which BAN is active (null = no ban).

 /**
  * Personality/behavior traits used in multiple decision rules.
  *
  * ## Contract
  * Provides numeric trait values used as inputs for attractiveness/risk and theft/behavior heuristics.
  *
  * ## Invariants
  * Current PoC logic treats these as percentage-like scores:
  * - expected range: 0..100 (inclusive)
  *
  * ## Determinism
  * Pure data container.
  *
  * @property greed Greed score (expected 0..100). Higher => stronger preference for personal gain (e.g., salvage value, theft temptation).
  * @property honesty Honesty score (expected 0..100). Higher => reduced theft temptation / more compliant behavior.
  * @property courage Courage score (expected 0..100). Higher => higher risk tolerance / lower danger penalty.
