+- **Orchestrator:** `ContractGeneratorOperations.TryIssue` — band + faction template selection, deterministic id, store persist.
+- **Tests:** `ContractGeneratorOperationsTests` (11 unit), `ContractGeneratorOperationsIntegrationTests` (DI), `ContractGeneratorPersistenceIntegrationTests` (`RequirePostgresFact`); **888** tests green.

When Postgres is configured, **`PostgresContractInstanceStore`** persists to **`contract_instance`** ([`V011__contract_instance.sql`](../db/migrations/V011__contract_instance.sql)) with a partial unique index enforcing one active row per player.

+## Contract generator operations (NEO-147)
+
+**`ContractGeneratorOperations.TryIssue`** issues an **`active`** contract instance from seed inputs + player context. Call this orchestrator (or future HTTP wrapper) — not **`IContractInstanceStore.TryCreateActive`** directly — so template selection, faction gates, and deterministic ids stay centralized.
+
+**Inputs:** `playerId`, optional `templateId`, `seedBucket`, optional `zoneDifficultyBand` (defaults to **1**).
+
+**Template selection:**
+
+- **Explicit `templateId`:** registry lookup; deny **`unknown_template`** when missing; deny **`no_eligible_template`** when band or faction standing floor fails.
+- **Omitted/empty `templateId`:** first template from **`GetDefinitionsInIdOrder()`** matching band + standing.
+- Faction floor uses **`FactionGateOperations`** on the template **`minFactionStanding`** row.
+
+**Deterministic instance id:** **`ContractInstanceIds.MakeDeterministicInstanceId`** — SHA-256 of `{playerId}|{templateId}|{seedBucket}` (normalized) → **`ci_{32 lowercase hex}`**.
+
+**Reason codes:**
+
+| Code | When |
+|------|------|
+| **`invalid_ids`** | Empty player or seed bucket after normalize |
+| **`player_not_writable`** | Player not in dev bucket / Postgres `player_position` |
+| **`active_contract_exists`** | Player already has an active instance |
+| **`unknown_template`** | Explicit template id not in registry |
+| **`no_eligible_template`** | No template matches band + standing filters |
+
+**Result:** **`ContractIssueOperationResult`** — `success`, optional `reasonCode`, optional **`ContractInstanceState`** snapshot, **`encounterTemplateId`** from the selected template.
+
+Economy band-cap lint at issue time lands in **NEO-150** (E7M4-07). HTTP **`POST …/contracts/issue`** lands in **NEO-151** (E7M4-08). Plan: [NEO-147 implementation plan](../../docs/plans/NEO-147-implementation-plan.md).

 ## Contract outcome store (NEO-146)
 
 Append-only contract completion audit rows live in **`IContractOutcomeStore`**. Each **`ContractOutcomeRow`** captures instance id, delivery idempotency key **`{playerId}:contract_complete:{contractInstanceId}`**, grant snapshot summary (items, skill XP, reputation — same shapes as **`RewardDeliveryEvent`**), and **`recordedAt`**.
