 Persistence rule: learning state should make a returning character feel
 continuous while giving designers enough history to tune teaching, feedback, and
 anti-exploit behavior.

+## Multiplayer Learning Rules
+
+Learning in multiplayer should make cooperation valuable without turning nearby
+players into passive experience sources.
+
+Teaching:
+
+- The server validates teaching credit.
+- The teacher must know the concept, have enough practical experience, or
+  demonstrate the action in the current context.
+- The learner must be nearby, attentive, and eligible for the concept.
+- Teaching grants bounded awareness or practice credit, not instant mastery.
+- Dangerous concepts require supervised practice before full confidence is
+  awarded.
+
+Observation:
+
+- Nearby observation can unlock awareness of a concept when the action is
+  visible and relevant.
+- Passive observation grants less credit than direct practice.
+- Repeated passive observation has diminishing returns.
+- Observation does not grant credit while idle, disconnected, hidden from the
+  action, or outside the relevant range.
+
+Shared work:
+
+- Group tasks can grant role-specific experience to active contributors.
+- Roles should be explicit enough to audit later: gatherer, builder, fire
+  watcher, first aid helper, scout, teacher, cook, hauler, or defender.
+- Failed group work can teach useful feedback when a player helps diagnose or
+  correct the problem.
+- Idle proximity, item handoff spam, and repeated low-risk loops should not
+  grant shared-work credit.
+
+Group skill benefits:
+
+- Skilled contributors can reduce risk, improve quality, increase speed, or
+  make warnings more visible for the group task.
+- Benefits should be capped so one expert does not remove all challenge.
+- Benefits apply only while the contributor is present, equipped, and actively
+  helping.
+- No global aura: skill benefits do not apply across the map or while logged
+  off unless a future offline-simulation rule explicitly grants protection.
+
+Network rules:
+
+- Client learning requests are hints only.
+- Server authority validates distance, visibility, participation, role,
+  cooldown, tools, environmental context, and outcome before granting credit.
+- Teaching, observation, and shared-work events must be persisted for tuning and
+  anti-exploit review.
+
+Multiplayer rule: cooperation should transfer awareness, improve group outcomes,
+and reward active contribution without bypassing practice, risk, or context.
