     logs. Waterfall mist is anchored to the waterfall instead of the village
     origin, duplicate wind layers are separated, and Metal smoke/wind
     materials retain restrained transparency.
+17. Coherent breeze pass: overlapping valley-wide white stroke/speck emitters
+    were removed. Tree canopies now bend gently in one prevailing direction
+    with stable per-tree phase and slow gust variation, while chimney smoke
+    leans with the same breeze. Day/night lighting now follows the simulation
+    clock even when the world initializes first, with the sunrise/sunset tints
+    applied in the correct order. The gameplay camera remains unchanged.
+18. Stylized player readability: the remaining gray player capsule is replaced
+    by a compact multi-part figure with a warm scarf/satchel accent and
+    velocity-driven walk motion. Collision, controls, and the elevated
+    staggered follow camera remain unchanged.
+19. Event-caused trust consequence: hungry familiar NPCs can gain directed
+    trust from a real food-deposit event, retain that event as the inspectable
+    cause, and redirect ordinary work to help a starving acquaintance. The
+    state is versioned and deterministic rather than presentation-only flavor.
+20. Calligraphic gust ambience: one terrain-aware controller now emits only
+    two or three tapered sage/amber/aqua ribbons at a time, with long quiet
+    intervals and a shared canopy/smoke direction. The shader draws each line
+    head-to-tail like a soft brush mark; repeated bursts cannot stack into the
+    old scratch/gnat field.
+21. Witnessed event knowledge: objective food-deposit events create separate
+    known-event references for their actor and nearby living NPCs. Knowledge
+    gates trust, produces a real informed-versus-uninformed choice divergence,
+    survives schema-v5 save/load, and appears in the NPC inspector.
 
 Next:
 
-1. Replace the remaining player capsule with a matching stylized presentation,
-   while preserving the elevated top-down follow, gentle dead-zone lag, and
-   cozy farm-builder readability.
-2. Continue with the relationship consequence work in `LEARNING_ROADMAP.md`
-   before expanding visual scope further.
+1. Add one provenance-aware NPC-to-NPC fact transfer, then bounded
+   importance/retention rules, as sequenced in `LEARNING_ROADMAP.md`.
 
 Do not start with GIS data, a full city, a large asset pack, or more NPC
 mechanics. The next proof is a beautiful stage for the systems that already
