/**
|
||||
* Component 17 — Heuristic bot players.
|
||||
*
|
||||
* Dev-side only: this ships nowhere. Its job is to play well enough that the balance harness
|
||||
* (component 18) produces numbers worth trusting. See architecture/components.md §2 D.17.
|
||||
*
|
||||
* A bot that plays LEGALLY is easy; one that plays WELL enough to judge balance is the harder
|
||||
* half, and this is only the first attempt. Read the numbers it produces as a floor on what a
|
||||
* competent human would score, not a prediction of one.
|
||||
*
|
||||
* THE POLICY, from the economy in docs/rules/card-reference.md §7. Local Operations actions are
|
||||
* the currency — one per Stage, twelve per Day, roughly one Revenue point each — so the bot's
|
||||
* whole job is deciding which of the three options to spend the Stage on:
|
||||
*
|
||||
* 1. Develop first. A Whistle Post is not a Passenger Facility and earns nothing from
|
||||
* passengers, so upgrading and placing freight facilities dominates early.
|
||||
* 2. Then keep the pipeline fed. Stocking a green box is what converts an action into a point.
|
||||
* 3. Switch when a train is standing at the Office, because spotted cars are what let a load
|
||||
* complete at all.
