+- `PlayerStandingRecord` is a versioned, deterministic 0–100 reputation with
+  named tiers (Stranger, Known Hand, Trusted, Village Steward, Voice of Jajce)
+  and per-requester gratitude, persisted through world schema v12;
+- `PlayerQuestRecord` plus `PlayerQuestSystem` turn real open needs into named
+  player quests: an unassisted pantry or wood shortage (or a hungry,
+  player-feedable animal) generates one quest for its requester, resolved only
+  by a real player supply or feed event through the ordinary economy;
+- completing a quest grants Standing and raises the requester's gratitude, an
+  NPC who trusts the player personally can ask them directly even when another
+  capable helper exists, and tier advances emit a celebration beat;
+- a read-only `QuestJournalHud` surfaces the active quest, Standing tier, and
+  gratitude feedback without entering saves or drawing RNG;
+- headless, runtime, schema-restore, and GUT unit regressions cover generation,
+  completion, invalidation, animal care, personal requests, and tier
+  progression.
