Review-first netcode slice (design review wf_900e9965-8f0 -> 11 folded;
post-impl wf_5c8299f8-299 clean). A PERMANENT periodic telegraphed AoE in
Blight-biome rooms only; one new [GhostField] uint NextEruptTick.
- Geyser component + GeyserEruptSystem (server): inverted invalid-tick guard
(a baked-0 tick must NEVER erupt -> lazy-stamps born-correct instead of the
party-wiping per-tick barrage), inline both-sides gather (SourceNetworkId=-1),
reschedule = now + period (never +=), never destroyed.
- GeyserTelegraphSystem (client): absolute-tick growing warning disc +
erupt burst on the >0->=<0 crossing, latched per NextEruptTick + arm-guard
(never edge-detects the replicated field -> no phantom on 0->stamp /
relevancy re-entry). Reuses ScorchDecalSystem + DynamicLightSystem.
- Seeded in RoomFieldSystem (Blight-gated on plan.Biome, born-correct staggered
stamp from live ServerTick), GeyserFieldSpawner + authoring wired into the
Gameplay subscene. Geyser.prefab duplicated from ResourceNode (no collider).
- BuildDisc promoted to FeedbackFx (shared with the barrel fuse ring).
- 474/474 EditMode incl. the unstamped-storm regression; live no-storm end-to-end.

All procedural, client-only, observe-only in PresentationSystemGroup, zero
netcode surface (read existing replicated state). Shared FeedbackFx decal
primitives (scorch blob + crack star meshes + transparent decal material).
ScorchDecalSystem: static RequestScorch queue -> pooled fading discs
(mirrors DynamicLightSystem), wired from the barrel boom, reusable by the
geyser. CoverDamageSystem: crack accretion keyed on BlightClutter.Remaining
(Variant 4) + proximity-gated shatter-scorch. RoomDressingSystem: persistent
arena scars on a distinct hash sub-stream, torn down with dressing. Knobs in
DecalConfig. Cover cracks use decals (not URPMaterialPropertyBaseColor) because
the Synty prop shader is not Hybrid-Per-Instance.

New FeedbackFx static (MakeClip/MakeParticleMaterial/MakeBurst/PlayClip/EmitTinted/EmitAt); the 3 *FeedbackSystem copies + AmbientAudio.MakeSting now route through it via 'using static'. MakeBurst takes the FX-root + the per-use gravity/radius/sizeTail that were the only diffs between copies; MakeClip folds in noise + decay. Behaviour-identical by construction (every particle/clip param preserved exactly).
459/459 EditMode tests pass; compiles clean. VFX are presentation-only (no EditMode coverage) -> wants a Play-mode smoke to eyeball hit/death/harvest/structure bursts.
