Vertical slice of the ecology engine (epic #250), per docs/superpowers/specs/2026-08-02-ecology-slice-design.md. Two exemplars on one generic engine to prove extend-by-type + variable per-species lifecycles.

Missing parts (checklist)

NaturalNode runtime entity + data-driven species/lifecycle table content/ecology.txt (pine 4-stage, rock 2-stage)
HarvestSystem (server-paced, clone of SpellSystem.Step) + HarvestRequest(NodeId) intent + trust-boundary validation (stage/range/LoS/tool/cooldown/skill)
SkillName += Lumberjacking, Mining (appended) + SkillCatalog rows + new SkillFormulas.HarvestChance(skill, difficulty)
baseline-deterministic + delta persistence (world-owned blobs, self-GC on regrow) + lazy time-derived growth (wallclock, no scheduler, offline recovery)
EcologySpawner deterministic per-chunk baseline + placement validation (road/water/off-map/occupied/slope) + Chebyshev spacing incl. cross-chunk boundary
AoI reconcile via InterestDiff + NaturalNode{Spawned,Changed,Removed} DTOs + bump ProtocolVersion.Current + new SystemMessageId cues
client node entity in ClientWorld + dispatcher cases + occlusion-fade coverage for tall nodes + anchor stability across stages + harvest swing VFX
assets (owner-generated, prompts on demand): temperate_pine_stump, item_wood_logs, item_axe, ore_outcrop, ore_outcrop_depleted, item_ore, item_pickaxe (+ verify young_pine_tree as pine sapling)
docs/game-design/systems/ecology.md + docs/uo-asset-map.md rows

Definition of Done

Spawner-placed pine+rock (no hand-painting); chop pine -> wood_logs + stump, server-paced (client can't rush/fake), regrows over time incl. offline; mine rock -> ore + depleted, regrows; both survive save/restart; AoI spawn/change/remove only to nearby observers; a second species/bush is a data row + assets. Base DoD: dotnet test green, whole build, 0 warnings. Invariants Check persisted in the spec.
