+
+## Quick Start
+
+1. Add the package to your project (local package in `Packages/`).
+2. **Create a table**: `Assets → Create → Jovian → Encounter System → Encounter Table`.
+3. **Create a collection**: `Assets → Create → Jovian → Encounter System → Encounters Collection`, drag tables into its array.
+4. In the table inspector, add encounters to the list. For each: pick the **kind** in the dropdown, fill in shared fields (id/name/description), and populate the kind-specific payload.
+5. For a quest chain, set `QuestKind.nextEncounter` on each step — pick the target table, then pick the encounter inside it.
+6. **Browse everything**: `Jovian → Encounters → Encounter Browser` for a searchable, filterable list view.
+
+## Key Concepts
+
+### `Encounter` is one class; `IEncounterKind` is where types live
+
+A single concrete `Encounter` carries shared fields (`EncounterDefinition`, `EncounterProperties`, `EncounterVisuals`, `EncounterDialogOptionSet`). Its `Kind` property is a `[SerializeReference, SubclassSelector]` polymorphic slot. Adding a new kind is one small class:
+
+```csharp
+[Serializable]
+public class MerchantKind : IEncounterKind {
+    public string shopInventoryId;
+    public float priceMultiplier = 1f;
+}
+```
+
+The editor dropdown picks it up automatically via reflection. No base class to extend, no subclass of `Encounter` to write.
+
+### Dialog option events are designer-authored, code-dispatched
+
+Each `EncounterDialogOption` holds an ordered `List<IEncounterEvent>` (also `[SerializeReference, SubclassSelector]`). Events are data only — what happens when the option is chosen is determined by handlers registered on `EncounterResolver`:
+
+```csharp
+var resolver = new EncounterResolver();
+resolver.Register<StartCombatEvent>((evt, ctx) => combatSystem.Start(evt.combatEncounterId));
+resolver.Register<ChainToEncounterEvent>((evt, ctx) => encounterFlow.GoTo(evt.nextEncounterId));
+resolver.Register<LogEvent>((evt, _) => Debug.Log(evt.message));
+
+// When the player picks an option:
+resolver.Resolve(chosenOption.events, new EncounterContext(currentEncounter));
+```
+
+### Rewards are reusable assets, referenced by events
+
+`Reward` is a ScriptableObject — one file per reusable reward (`10_Gold.asset`, `Rusty_Sword.asset`, `Unlock_Riverfort.asset`). Each asset has shared metadata (id, display name, icon) plus a polymorphic `IRewardKind` payload:
+
+```csharp
+[Serializable]
+public class PotionOfHealingRewardKind : IRewardKind {
+    public int healAmount = 50;
+}
+```
+
+To grant rewards, drop `GiveRewardEvent`s onto a dialog option and assign a `Reward` asset to each. Multiple rewards = multiple events — the resolver iterates them in order.
+
+Game-side wiring applies the reward:
+
+```csharp
+resolver.Register<GiveRewardEvent>((evt, ctx) => rewardApplier.Apply(evt.reward, ctx));
+```
+
+`rewardApplier` lives in game code — the package ships only the data types.
+
+### Cross-table references via `EncounterLink`
+
+`EncounterLink` stores a table asset + stable `internalId` GUID. Rename-safe (the GUID doesn't change) and diffable. The custom drawer renders two dropdowns: first pick a table, then pick an encounter inside it.
+
+### Gated quest progression
+
+`QuestProgress` walks an `EncountersCollection` at construction and builds a map of "predecessor quest encounter" for every target of a `QuestKind.nextEncounter`. An encounter is gated iff its predecessor hasn't been resolved:
+
+```csharp
+var questProgress = new QuestProgress(encountersCollection);
+
+// When rolling from a table, exclude gated entries:
+var next = table.GetRandomEncounter(e => !questProgress.IsGated(e));
+
+// After showing any encounter to the party:
+questProgress.OnEncounterTriggered(shown);
+```
+
+Progression fires `QuestStarted` / `QuestAdvanced(from, to)` / `QuestCompleted` events. Single-step quests (root with no `nextEncounter`) fire both `QuestStarted` and `QuestCompleted`.
+
+### Quest log (serialisable record)
+
+`QuestLog` subscribes to the three `QuestProgress` events and appends a `QuestLogEntry` for each. `CreateSnapshot()` returns the save payload; `Restore(saved)` rehydrates. Pair it with `QuestProgress.LoadResolvedIds(questLog.ResolvedEncounterIds())` on load to restore the gating set.
+
+## Runtime API Cheatsheet
+
+```csharp
+// Encounter rolling with gating
+IEncounter next = table.GetRandomEncounter(e => !questProgress.IsGated(e));
+
+// Resolving a picked dialog option
+resolver.Resolve(chosenOption.events, new EncounterContext(currentEncounter));
+
+// After any encounter fires
+questProgress.OnEncounterTriggered(shown);
+
+// Save/load quest state
+save.questLogEntries  = questLog.CreateSnapshot();
+questLog.Restore(save.questLogEntries);
+questProgress.LoadResolvedIds(questLog.ResolvedEncounterIds());
+
+// Fast id → encounter lookup
+encounterRegistry.GetEncounters().TryGetValue(id, out var encounter);
+```
+
+## Menu Items
+
+| Menu Path | Description |
+|-----------|-------------|
+| Assets → Create → Jovian → Encounter System → Encounter Table | New table asset |
+| Assets → Create → Jovian → Encounter System → Encounters Collection | New collection asset |
+| Assets → Create → Jovian → Encounter System → Dialog Option Set | New dialog option set |
+| Assets → Create → Jovian → Encounter System → Encounter Registry | New registry asset |
+| Jovian → Encounters → Encounter Browser | Searchable designer browser |
+| Jovian → Encounters → Validate All | Scan all tables/rewards for issues, print click-through report |
+
+## Composition Pattern
+
+Per the project's composition-over-inheritance stance, extending behaviour means:
+
+- **New encounter type?** Add a new `IEncounterKind` implementation.
+- **New dialog side effect?** Add a new `IEncounterEvent` + `resolver.Register<T>`.
+- **Never** subclass `Encounter` or stack `IEncounter` inheritance chains.
+
+Inheritance is only used where Unity effectively requires it — ScriptableObject assets (`EncounterTable`, `EncountersCollection`, `EncounterDialogOptionSet`, `EncounterRegistry`) and the `EncounterReference` MonoBehaviour scaffold.
+
+## Known Fragilities
+
+- `[SerializeReference]` stores the concrete type's full name + assembly in the YAML. Renaming or moving an `IEncounterKind` or `IEncounterEvent` class drops existing instances silently. Use `[MovedFrom]` when refactoring:
+  ```csharp
+  [MovedFrom("Jovian.EncounterSystem", "Jovian.EncounterSystem", "StartCombatEvent")]
+  public class BeginCombatEvent : IEncounterEvent { ... }
+  ```
+- `EncounterDefinition.internalId` is a GUID created at class construction. If you duplicate an encounter by copying YAML, dedupe the id before saving — otherwise `EncounterLink` lookups become ambiguous.
