+# NEO-151 — E7M4-08: Contract issue POST + per-player contract GET
+
+**Linear:** [NEO-151](https://linear.app/neon-sprawl/issue/NEO-151)  
+**Branch:** `NEO-151-e7m4-08-contract-issue-post-per-player-contract-get`  
+**Backlog:** [E7M4-pre-production-backlog.md](E7M4-pre-production-backlog.md) — **E7M4-08**  
+**Module:** [E7_M4_ContractMissionGenerator.md](../decomposition/modules/E7_M4_ContractMissionGenerator.md)  
+**Pattern:** [NEO-120-implementation-plan.md](NEO-120-implementation-plan.md) (`QuestAcceptApi` issue envelope); [NEO-129-implementation-plan.md](NEO-129-implementation-plan.md) (`completionRewardSummary` on GET rows); [NEO-147-implementation-plan.md](NEO-147-implementation-plan.md) (`ContractGeneratorOperations.TryIssue`); [NEO-149-implementation-plan.md](NEO-149-implementation-plan.md) (encounter clear → completion + delivery)  
+**Precursors:** [NEO-149](https://linear.app/neon-sprawl/issue/NEO-149) **`Done`** — `ContractCompletionOperations` + encounter wiring; [NEO-150](https://linear.app/neon-sprawl/issue/NEO-150) **`Done`** — issue-time economy validation (**on `main`**)  
+**Blocks:** [NEO-152](https://linear.app/neon-sprawl/issue/NEO-152) (telemetry hook sites), [NEO-153](https://linear.app/neon-sprawl/issue/NEO-153) (Godot contract HUD)  
+**Client counterpart:** [NEO-153](https://linear.app/neon-sprawl/issue/NEO-153) — contract panel after this story lands
+
+## Goal
+
+Client-readable contract issuance and state without local math — **`POST …/contracts/issue`** returns an **`active`** instance projection; **`GET …/contracts`** lists the player's active contract (if any) plus recent completed rows with encounter objective id and delivery summary.
+
+## Kickoff clarifications
+
+| Topic | Question | Agent recommendation | Answer |
+|-------|----------|---------------------|--------|
+| GET completed history depth | How many completed rows alongside active? | **Active (0–1) + up to 10 recent completed**, ordered by **`issuedAt` desc** | **Adopted** — user chose cap 10 |
+| POST body shape | Full `contract-seed` vs path-only player id? | **Full seed fields + `schemaVersion` 1**; **`playerId` in body must match path `{id}`** (400 on mismatch); **`templateId` required** per schema + NEO-147 | **Adopted** — schema + NEO-147 precedent |
+| Issue response envelope | Raw snapshot vs structured response? | **`{ issued, reasonCode, contract }`** mirroring quest accept **`{ accepted, reasonCode, quest }`** | **Adopted** — NEO-120 pattern |
+| Grant summary DTOs | New contract types vs reuse quest summary? | **Reuse `QuestCompletionRewardSummaryJson`** and grant line types — same `IRewardDeliveryStore` snapshot shape | **Adopted** — NEO-129/NEO-140 |
+| Store read for GET | Extend `IContractInstanceStore` vs ad-hoc SQL in API? | **Add `ListForPlayer(playerId, maxCompletedRows)`** on interface + both store impls | **Adopted** — store boundary precedent (NEO-146) |
+| Issue deny HTTP status | 400 vs 200 with `issued: false`? | **200 OK** with **`issued: false`** + **`reasonCode`** (and optional **`contract`** snapshot on `active_contract_exists`) | **Adopted** — quest accept precedent |
+| Bruno scope | Minimal vs full issue → clear → GET loop? | **`bruno/neon-sprawl-server/contracts/`** — issue, GET default, GET after encounter clear (reuse ability-cast / encounter clear spine) | **Adopted** — backlog in-scope |
+| Telemetry / Godot | In scope? | **Out of scope** — NEO-152 comment hooks; NEO-153 client HUD | **Adopted** — backlog |
+
+## Scope and out-of-scope
+
+**In scope (from Linear + backlog):**
+
+- **`POST /game/players/{id}/contracts/issue`** — `ContractIssueApi` + request/response DTOs; delegates to **`ContractGeneratorOperations.TryIssue`** with full DI registries (encounter, item, skill, faction per NEO-150 handoff).
+- **`GET /game/players/{id}/contracts`** — `ContractListApi` + list DTOs; active row + up to **10** recent completed instances with template summary, **`encounterTemplateId`**, **`completionRewardSummary`** when delivered.
+- **`IContractInstanceStore.ListForPlayer`** — read path for completed history (in-memory + Postgres).
+- Integration tests (`ContractIssueApiTests` / `ContractListApiTests` or combined `ContractApiTests`).
+- Bruno **`bruno/neon-sprawl-server/contracts/`** — issue → encounter clear → GET loop; update contract-stores reset bru cross-link.
+- `server/README.md` contract HTTP sections; E7.M4 module anchor.
+
+**Out of scope (from Linear + backlog):**
+
+- Godot parse/HUD (**NEO-153** / E7M4-10).
+- Telemetry comment hooks (**NEO-152** / E7M4-09).
+- Optional **`templateId`** auto-select over HTTP (ops layer supports null; HTTP requires explicit id per schema).
+- Live E4.M1 zone read for **`zoneDifficultyBand`** (POST override only until E4.M1).
+
+**Client counterpart:** [NEO-153](https://linear.app/neon-sprawl/issue/NEO-153) — server HTTP must land in this story first.
+
+## Acceptance criteria checklist
+
+- [ ] POST issue returns **`active`** instance JSON.
+- [ ] GET lists active contract with encounter objective id.
+- [ ] GET completed row includes delivery summary after encounter clear.
+
+## Technical approach
+
+### 1. Store read — `IContractInstanceStore.ListForPlayer`
+
+```csharp
+IReadOnlyList<ContractInstanceState> ListForPlayer(string playerId, int maxCompletedRows);
+```
+
+**Semantics:**
+
+- Normalize **`playerId`**; return empty list when player not writable / unknown to store.
+- If an **active** row exists, include it first (at most one).
+- Append up to **`maxCompletedRows`** **completed** instances for that player, **`issuedAt` descending** (tie-break **`contractInstanceId`** ordinal).
+- Prototype constant **`ContractListApi.MaxCompletedRows = 10`** (kickoff decision).
+
+**Postgres:** `SELECT … WHERE player_id = @pid AND status = 'completed' ORDER BY completed_at DESC NULLS LAST, contract_instance_id LIMIT @n` plus existing active query.
+
+**In-memory:** scan **`byInstanceId`** for player-owned completed rows, sort, take N, prepend active.
+
+Unit tests in **`InMemoryContractInstanceStoreTests`**: empty player, active only, completed only, active + multiple completed ordering, cap respected.
+
+### 2. DTOs (`Game/Contracts/ContractApiDtos.cs`)
+
+| Type | Role |
+|------|------|
+| **`ContractIssueRequest`** | `schemaVersion` **1**, `playerId`, `templateId`, `seedBucket`, optional `zoneDifficultyBand` — mirrors [`contract-seed.schema.json`](../../content/schemas/contract-seed.schema.json) + version gate |
+| **`ContractIssueResponse`** | `schemaVersion`, `issued`, optional `reasonCode`, optional **`ContractInstanceRowJson`** |
+| **`ContractListResponse`** | `schemaVersion`, `playerId`, **`contracts`** array |
+| **`ContractInstanceRowJson`** | `contractInstanceId`, `templateId`, `templateDisplayName`, `status` (`active` \| `completed`), `encounterTemplateId`, `seedBucket`, `issuedAt`, optional `completedAt`, optional **`completionRewardSummary`** (`QuestCompletionRewardSummaryJson`) |
+
+**Row mapping (`ContractListApi.MapInstanceRow`):**
+
+1. Load template via **`IContractTemplateRegistry.TryGetDefinition`** for **`templateDisplayName`** + **`encounterTemplateId`** fallback.
+2. For **`completed`** status, **`IRewardDeliveryStore.TryGet(playerId, RewardDeliverySourceKinds.ContractCompletion, contractInstanceId, …)`** → map grants via same helpers as **`QuestProgressApi.MapCompletionRewardSummary`** (extract shared mapper or duplicate minimally — prefer internal reuse on **`QuestProgressApi`** mappers if accessible, else parallel private helpers in contract API).
+
+### 3. `ContractIssueApi`
+
+**Route:** `POST /game/players/{id}/contracts/issue`
+
+**Handler flow:**
+
+1. **400** when body null, **`schemaVersion`** mismatch, empty **`templateId`** / **`seedBucket`**, or body **`playerId`** ≠ trimmed path **`{id}`** (case-sensitive ordinal after trim — match inventory/quest normalization).
+2. **404** when path player unknown (**`IPositionStateStore`** gate — same as quest progress).
+3. Call **`ContractGeneratorOperations.TryIssue`** with path player id, body fields, and injected registries/stores (**mirror `ContractGeneratorOperationsIntegrationTests`** DI wiring).
+4. **200** **`ContractIssueResponse`** via **`MapIssueResponse`** — on success map **`ContractInstanceRowJson`** from result snapshot + template registry; on deny include **`reasonCode`** and optional snapshot row (e.g. **`active_contract_exists`**).
+
+Register in **`Program.cs`** alongside quest routes: **`app.MapContractIssueApi()`**.
+
+### 4. `ContractListApi`
+
+**Route:** `GET /game/players/{id}/contracts`
+
+**Handler flow:**
+
+1. **404** unknown player (position gate).
+2. **`instanceStore.ListForPlayer(trimmedId, ContractListApi.MaxCompletedRows)`**.
+3. Map each snapshot to **`ContractInstanceRowJson`**.
+4. **200** **`ContractListResponse`** — **`contracts`** may be empty array.
+
+### 5. Integration tests (`ContractApiTests`)
+
+| Test | Covers |
+|------|--------|
+| POST issue 404 unknown player | Position gate |
+| POST issue 400 schema / playerId mismatch | Request validation |
+| POST issue 200 happy path | **`issued: true`**, **`active`**, **`encounterTemplateId: prototype_combat_pocket`**, deterministic **`contractInstanceId`** |
+| POST issue 200 deny second active | **`issued: false`**, **`active_contract_exists`**, optional active row echo |
+| GET 404 unknown player | Position gate |
+| GET empty list | Known player, no instances |
+| GET active after issue | Active row with encounter id, no summary |
+| GET completed after encounter clear | Issue → **`ContractCompletionOperations.TryCompleteOnEncounterClear`** (or ability-cast integration path) → GET asserts **`completed`**, **`completionRewardSummary`** with prototype bundle lines |
+| GET idempotent replay | Second GET same summary (mirror NEO-129) |
+
+Optional **`RequirePostgresFact`**: issue + list round-trip on Postgres store (mirror NEO-146 persistence tests).

+## Tests
+
+| File | What it covers |
+|------|----------------|
+| `InMemoryContractInstanceStoreTests` | **`ListForPlayer`**: empty, active-only, completed cap, ordering |
+| `ContractApiTests` | POST issue happy/deny paths; GET empty/active/completed + **`completionRewardSummary`**; 404/400 gates |
+| `ContractGeneratorOperationsIntegrationTests` (existing) | Unchanged — orchestrator DI baseline |
+| CI | `dotnet test` green; Bruno manual against dev server |
+
+Manual Godot QA: **none** (server HTTP; capstone **NEO-154**). Bruno: **`contracts/`** folder per plan.
+
+## Open questions / risks
+
+| Question / risk | Agent recommendation | Status |
+|-----------------|----------------------|--------|
+| **`TryIssue` registry wiring in HTTP handler** | Pass same four registries as **`ContractGeneratorOperationsIntegrationTests`** — verified at kickoff (NEO-150 handoff) | `adopted` |
+| Duplicate grant-summary mapper vs quest API | Extract **`internal`** shared mapper on **`QuestProgressApi`** if clean; else parallel private helpers — keep grant order parity | `pending` |
+| GET payload size with 10 completed rows | Accept for prototype; client (**NEO-153**) reads active row first | `adopted` |
+| **`contract-seed.schema.json` lacks `schemaVersion`** | HTTP DTO adds **`schemaVersion`** alongside seed fields (quest/inventory precedent); schema file unchanged unless CI needs `$ref` later | `adopted` |
+| Postgres **`ListForPlayer`** index | Existing **`player_id`** + status filter sufficient for prototype volume; no new migration | `adopted` |
+
+## Client counterpart
+
+[NEO-153](https://linear.app/neon-sprawl/issue/NEO-153) — **`contract_client.gd`**, issue binding, HUD labels; blocked until this story merges. Surfaces deny codes including **`economy_cap_exceeded`** and **`invalid_reward_bundle`** from NEO-150.
