0048 — Pirate Ecosystem Dynamics: Self-Regulating Population

Status

Folded into SYSTEMS/pirate-ecosystem.md (re-verified 2026-08-06)

Context

Pirate Holdings (ADR-0047) seed an initial pirate population per region but define no dynamics for what happens after a player clears them. Arbitrated a self-regulating ecosystem model — a weighted population score with a suppression-modulated target, virus-like daughter spawning from existing holdings, and tier-evolution of untouched holdings — over static depletion or static accumulation.

Folded into SYSTEMS/pirate-ecosystem.md — the population-score formula, spawn/decay tables, evolution thresholds, and all worked algorithms now live in that doc's prose. This record is retained for decision history per the append-only ADR policy.
