refactor: centralize coverage exclusions for scoverage across modules

test: exclude core infrastructure files from coverage
Exclude from SonarQube coverage metrics: - Exception classes (ApiException, ApiExceptionMapper) - Configuration classes (JacksonConfig) - Data classes (GameEntry) - Registry implementation (GameRegistryImpl - has integration tests) These are infrastructure/config code with integration tests but not amenable to unit test coverage instrumentation.

-name: keep-structure-memory-updated
-description: Always update the project structure memory files when adding, removing, or changing source files
-type: feedback
---
-
-After any change that adds, removes, renames, or significantly alters a source file, update the relevant structure memory file:
-
- New/renamed/deleted file in `modules/api` → update `project_structure_api.md`
- New/renamed/deleted file in `modules/core` → update `project_structure_core.md`
- New module, dependency version change, or new top-level directory → update `project_structure_root.md`
- New module added → create a new `project_structure_<module>.md` and add it to `MEMORY.md`
-
-**Why:** Structure memories are the primary navigation aid. Stale entries cause wasted exploration.
-
-**How to apply:** Treat the structure memory update as part of completing any implementation task — do it in the same session, not as a follow-up.

-# Module: `modules/api`
-
-**Purpose:** Shared domain model — pure data types with no game logic. Depended on by `modules/core`.
-
-**Gradle:** `id("scala")`, no `application` plugin. No Quarkus. Uses scoverage plugin.
-
-**Package root:** `de.nowchess.api`

-### `board/`
-| File | Contents |

-| `Board.scala` | `opaque type Board = Map[Square, Piece]` — extensions: `pieceAt`, `withMove`, `pieces`; `Board.initial` sets up start position |
-| `Color.scala` | `enum Color { White, Black }` — `.opposite`, `.label` |
-| `Piece.scala` | `case class Piece(color, pieceType)` — convenience vals `WhitePawn`…`BlackKing` |
-| `PieceType.scala` | `enum PieceType { Pawn, Knight, Bishop, Rook, Queen, King }` — `.label` |
-| `Square.scala` | `enum File { A–H }`, `enum Rank { R1–R8 }`, `case class Square(file, rank)` — `.toString` algebraic, `Square.fromAlgebraic(s)` |

-| `ApiResponse.scala` | `sealed trait ApiResponse[+A]` → `Success[A](data)` / `Failure(errors)`; `case class ApiError(code, message, field?)`; `case class Pagination(page, pageSize, totalItems)` + `.totalPages`; `case class PagedResponse[A](items, pagination)` |
-
-## Test files (`src/test/scala/de/nowchess/api/`)
-Mirror of main structure — one `*Test.scala` per source file using `AnyFunSuite with Matchers`.
-
-## Notes
- `GameState` is FEN-style but `Board` (in `core`) is a `Map[Square,Piece]` — the two are separate representations
- `CastlingRights` is defined here in `api`; the castling logic lives in `core`

-type: project

-
-# Module: `modules/core`
-
-**Purpose:** Standalone TUI chess application. All game logic, move validation, rendering. Depends on `modules/api`.
-
-**Gradle:** `id("scala")` + `application` plugin. Main class: `de.nowchess.chess.Main`. Uses scoverage plugin.
-
-**Package root:** `de.nowchess.chess`
-
-## Source files (`src/main/scala/de/nowchess/chess/`)
-
-### Root
-| File | Contents |
-|------|----------|
-| `Main.scala` | Entry point — prints welcome, starts `GameController.gameLoop(GameContext.initial, Color.White)` |
-
-### `controller/`
-| File | Contents |
-|------|----------|
-| `GameController.scala` | `sealed trait MoveResult` ADT: `Quit`, `InvalidFormat`, `NoPiece`, `WrongColor`, `IllegalMove`, `Moved`, `MovedInCheck`, `Checkmate`, `Stalemate`; `object GameController` — `processMove(ctx, turn, raw): MoveResult` (pure), `gameLoop(ctx, turn)` (I/O loop), `applyRightsRevocation(...)` (castling rights bookkeeping) |
-| `Parser.scala` | `object Parser` — `parseMove(input): Option[(Square, Square)]` parses coordinate notation e.g. `"e2e4"` |
-
-### `logic/`
-| File | Contents |
-|------|----------|
-| `GameContext.scala` | `enum CastleSide { Kingside, Queenside }`; `case class GameContext(board, whiteCastling, blackCastling)` — `.castlingFor(color)`, `.withUpdatedRights(color, rights)`; `GameContext.initial`; `extension (Board).withCastle(color, side)` moves king+rook atomically |
-| `GameRules.scala` | `enum PositionStatus { Normal, InCheck, Mated, Drawn }`; `object GameRules` — `isInCheck(board, color)`, `legalMoves(ctx, color): Set[(Square,Square)]`, `gameStatus(ctx, color): PositionStatus` |
-| `MoveValidator.scala` | `object MoveValidator` — `isLegal(board, from, to)`, `legalTargets(board, from): Set[Square]` (board-only, no castling), `legalTargets(ctx, from)` (context-aware, includes castling), `isCastle`, `castleSide`, `castlingTargets(ctx, color)` — full castling legality (empty squares, no check through transit) |
-
-### `view/`
-| File | Contents |
-|------|----------|
-| `Renderer.scala` | `object Renderer` — `render(board): String` outputs ANSI-colored board with file/rank labels |
-| `PieceUnicode.scala` | `extension (Piece).unicode: String` maps each piece to its Unicode chess symbol |
-
-## Test files (`src/test/scala/de/nowchess/chess/`)
-Mirror of main structure — one `*Test.scala` per source file using `AnyFunSuite with Matchers`.
-
-## Key design notes
- `MoveValidator` has two overloaded `legalTargets`: one takes `Board` (geometry only), one takes `GameContext` (adds castling)
- `GameRules.legalMoves` filters by check — it calls `MoveValidator.legalTargets(ctx, from)` then simulates each move
- Castling rights revocation is in `GameController.applyRightsRevocation`, triggered after every move
- No `@QuarkusTest` — this module is a plain Scala application, not a Quarkus service

+# NowChessSystems — Wiki
+
+_Generated 2026-04-12 — re-run `npx codesight --wiki` if the codebase has changed._
+
+Structural map compiled from source code via AST. No LLM — deterministic, 200ms.
+
+> **How to use safely:** These articles tell you WHERE things live and WHAT exists. They do not show full implementation logic. Always read the actual source files before implementing new features or making changes. Never infer how a function works from the wiki alone.
+
+## Articles
+
+- [Overview](./overview.md)
+
+## Quick Stats
+
+- Routes: **0**
+- Models: **0**
+- Components: **0**
+- Env vars: **0** required, **0** with defaults
+
+## How to Use
+
+- **New session:** read `index.md` (this file) for orientation — WHERE things are
+- **Architecture question:** read `overview.md` (~500 tokens)
+- **Domain question:** read the relevant article, then **read those source files**
+- **Database question:** read `database.md`, then read the actual schema files
+- **Before implementing anything:** read the source files listed in the article
+- **Full source context:** read `.codesight/CODESIGHT.md`
+
+## What the Wiki Does Not Cover
+
+These exist in your codebase but are **not** reflected in wiki articles:
+- Routes registered dynamically at runtime (loops, plugin factories, `app.use(dynamicRouter)`)
+- Internal routes from npm packages (e.g. Better Auth's built-in `/api/auth/*` endpoints)
+- WebSocket and SSE handlers
+- Raw SQL tables not declared through an ORM
+- Computed or virtual fields absent from schema declarations
+- TypeScript types that are not actual database columns
+- Routes marked `[inferred]` were detected via regex and may have lower precision
+- gRPC, tRPC, and GraphQL resolvers may be partially captured
+
+When in doubt, search the source. The wiki is a starting point, not a complete inventory.

+# NowChessSystems — Overview
+
+> **Navigation aid.** This article shows WHERE things live (routes, models, files). Read actual source files before implementing new features or making changes.
+
+**NowChessSystems** is a scala project built with raw-http.
+
+## High-Impact Files
+
+Changes to these files have the widest blast radius across the codebase:
+
+- `modules/api/src/main/scala/de/nowchess/api/game/GameContext.scala` — imported by **28** files
+- `modules/api/src/main/scala/de/nowchess/api/board/Square.scala` — imported by **21** files

-
-## Workflow
-1. **Plan** — restate requirement, list files, flag risks. Proceed unless genuine ambiguity.
-2. **Tests first** — cover only new behaviour.
-3. **Implement** — no scope creep.
-4. **Verify** — check each requirement; confirm green build.
-
-## Scala/Quarkus Rules
- `given`/`using` only (no `implicit`); `Option`/`Either`/`Try` (no `null`/`.get`)
- `jakarta.*` only; reactive I/O (`Uni`/`Multi`), no blocking on event loop
- Always exclude `org.scala-lang:scala-library` from Quarkus BOM
- Unit tests: `extends AnyFunSuite with Matchers` — no `@Test`, no `: Unit`
- Integration tests: `@QuarkusTest` + JUnit 5 — `@Test` methods need explicit `: Unit`
-
-## Coverage
-Line = 100% · Branch = 100% · Method = 100% · Regression tests · document exceptions
-Check: `jacoco-reporter/scoverage_coverage_gaps.py modules/{svc}/build/reports/scoverageTest/scoverage.xml`
-⚠️ Use `scoverageTest/`, NOT `scoverage/`.
-
-## Bug Fixing
-Fix failures immediately without asking. After 3 failed attempts → log in `docs/unresolved.md` + surface summary.
-
-## Agents (new service)
-Sequential: architect → scala-implementer → test-writer → gradle-builder → code-reviewer (review only, no self-fix)
-Parallel: only when services are fully independent (no shared contracts/state).
-
-## Unresolved (`docs/unresolved.md`)
-Append only, never delete:

+## Modules
+
+| Module | Role | Depends on |
+|--------|------|-----------|
+| `api`  | Model / shared types | (none) |
+| `core` | Primary business logic | api, rule |
+| `rule` | Game rules | api |
+| `bot`  | Bots and AI | api,rule,io |
+| `io`   | Export formats | api, core |
+| `ui`   | Entrypoint & UI | core, io |
+
+## Style
+
+- Immutable data, pure functions.
+- Functions under 30 lines. Need "and"? Split it.
+- Cyclomatic complexity under 15.
+- No comments. Names carry intent. Comment non-obvious algorithms only.
+- Scan duplicated logic. Extract.
+- Follow default Sonar style for Scala.
+- `Option`/`Either` for fallible ops. Skip exceptions for control flow.
+- Naming: types PascalCase, functions/values camelCase.
+
+## Code Quality
+
+- **Coverage:** 100% condition coverage required in `api`, `core`, `rule`, `io` (mandatory); `ui` exempt.
+
+### Linters
+
+- **scalafmt** — Enforces formatting. Check: `./gradlew spotlessScalaCheck`. Refactor: `./gradlew spotlessScalaApply`.
+- **scalafix** — Enforces style, detects unused imports/code. Run: `./gradlew scalafix`.
+
+## Architecture Decisions
+
+- **Immutable state as primary model:** GameContext (api) holds board, history, player state—immutable throughout. Each move → new GameContext. Enables undo/redo without side effects.
+- **Observer pattern for UI decoupling:** GameEngine publishes move/state events; CommandInvoker queues moves; UI listens (no polling). GameEngine never imports UI.
+- **RuleSet trait encapsulates rules:** Move generation, check, castling, en passant all in RuleSet impl. GameEngine calls rules as black box; rules don't know rest of core.
+- **Polyglot hash must follow spec index layout:** Piece keys use interleaved mapping `(pieceType * 2 + colorBit)` (black=0, white=1). Castling keys: `768..771`. En-passant file keys: `772..779`, XORed only if side-to-move has capturable en passant. Side-to-move key: `780` (white).
+- **Alpha-beta uses sequential PV search by default:** Parallel split disabled (fixed-window futures removed pruning effectiveness). Sequential PV default. Correctness + pruning quality > speculative parallelism.
+- **Search hash is updated incrementally per move:** Bot search updates Zobrist keys from parent hash with move deltas, not recomputing piece scans per node.
+
+## Rules
+
+- **Tests are the spec.** Don't modify to pass. Fix requirements/code. Update only if requirements change.
+- Never read build folders. Ask permission if needed.
+- Keep file current with decisions + conventions.

+## Instructions for Claude Code
+
+### Two-Step Rule (mandatory)
+**Step 1 — Orient:** Use wiki articles to find WHERE things live.
+**Step 2 — Verify:** Read source files from wiki BEFORE coding.
+
+Wiki = structural summaries (routes, models, file locations). No function logic, middleware internals, runtime behavior. Don't code from wiki alone—read sources.
+
+Read in order at session start:
+1. `.codesight/wiki/index.md` — orientation map (~200 tokens)
+2. `.codesight/wiki/overview.md` — architecture overview (~500 tokens)
+3. Domain article (e.g. `.codesight/wiki/auth.md`) → check "Source Files" section → read those files
+4. `.codesight/CODESIGHT.md` — full context map for deep exploration
+
+`[inferred]` routes = regex-detected. Verify sources. ⚠ in wiki? Re-run `codesight --wiki`.
+
+Or use the codesight MCP server for on-demand queries:
+- `codesight_get_wiki_article` — read a specific wiki article by name
+- `codesight_get_wiki_index` — get the wiki index
+- `codesight_get_summary` — quick project overview
+- `codesight_get_routes --prefix /api/users` — filtered routes
+- `codesight_get_blast_radius --file src/lib/db.ts` — impact analysis before changes
+- `codesight_get_schema --model users` — specific model details
+
+Consult codesight context first. Saves ~16.893 tokens/conversation.

+## graphify
+
+graphify knowledge graph at graphify-out/.
+
+Rules:
+- Architecture/codebase questions? Read graphify-out/GRAPH_REPORT.md (god nodes, communities).
+- graphify-out/wiki/index.md exists? Use it (not raw files).
+- Code modified? Run `python3 -c "from graphify.watch import _rebuild_code; from pathlib import Path; _rebuild_code(Path('.'))"` to sync graph.

+## Instructions for Claude Code
+
+### Two-Step Rule (mandatory)
+**Step 1 — Orient:** Use wiki articles to find WHERE things live.
+**Step 2 — Verify:** Read the actual source files listed in the wiki article BEFORE writing any code.
+
+Wiki articles are structural summaries extracted by AST. They show routes, models, and file locations.
+They do NOT show full function logic, middleware internals, or dynamic runtime behavior.
+**Never write or modify code based solely on wiki content — always read source files first.**
+
+Read in order at session start:
+1. `.codesight/wiki/index.md` — orientation map (~200 tokens)
+2. `.codesight/wiki/overview.md` — architecture overview (~500 tokens)
+3. Domain article (e.g. `.codesight/wiki/auth.md`) → check "Source Files" section → read those files
+4. `.codesight/CODESIGHT.md` — full context map for deep exploration
+
+Routes marked `[inferred]` in wiki articles were detected via regex — verify against source before trusting.
+If any source file shows ⚠ in the wiki, re-run `codesight --wiki` before proceeding.
+
+Or use the codesight MCP server for on-demand queries:
+- `codesight_get_wiki_article` — read a specific wiki article by name
+- `codesight_get_wiki_index` — get the wiki index
+- `codesight_get_summary` — quick project overview
+- `codesight_get_routes --prefix /api/users` — filtered routes
+- `codesight_get_blast_radius --file src/lib/db.ts` — impact analysis before changes
+- `codesight_get_schema --model users` — specific model details
+
+Only open specific files after consulting codesight context. This saves ~16.893 tokens per conversation.

+  title: NowChess Board API
+  description: |
+    REST API for the NowChess application. Designed to feel familiar to users
+    of the [lichess API](https://lichess.org/api).
+
+    ## Authentication
+    Most endpoints require a Bearer token:
+    ```
+    Authorization: Bearer <token>
+    ```
+    Authentication is reserved for future implementation — endpoints are currently
+    open unless noted otherwise.
+
+    ## Move notation
+    Moves are expressed in **UCI notation**: `{from}{to}[promotion]`
+    - Normal move: `e2e4`
+    - Capture: `d5e6`
+    - Promotion: `e7e8q` (q=queen, r=rook, b=bishop, n=knight)
+    - Castling: `e1g1` (kingside white), `e1c1` (queenside white)
+
+    ## Streaming
+    Endpoints that support streaming return **NDJSON** (newline-delimited JSON).
+    Request them with:
+    ```
+    Accept: application/x-ndjson
+    ```
+    Each line of the response is a complete JSON object. Empty lines are
+    keep-alive heartbeats.
+
+    ## Rate limiting
+    Requests that exceed the rate limit receive `429 Too Many Requests`.
+    Honour the `Retry-After` response header and wait before retrying.

-## [2026-03-31] Unreachable code blocking 100% statement coverage
-
-**Requirement/Bug:** Reach 100% statement coverage in core module.
-
-**Root Cause:** 4 remaining uncovered statements (99.6% coverage) are unreachable code:
-1. **PgnParser.scala:160** (`case _ => None` in extractPromotion) - Regex `=([QRBN])` only matches those 4 characters; fallback case can never execute
-2. **GameHistory.scala:29** (`addMove$default$4` compiler-generated method) - Method overload 3 without defaults shadows the 4-param version, making promotionPiece default accessor unreachable
-3. **GameEngine.scala:201-202** (`case _` in completePromotion) - GameController.completePromotion always returns one of 4 expected MoveResult types; catch-all is defensive code
-
-**Attempted Fixes:**
-1. Added comprehensive PGN parsing tests (all 4 promotion types) - PgnParser improved from 95.8% to 99.4%
-2. Added GameHistory tests using named parameters - hit `addMove$default$3` (castleSide) but not `$default$4` (promotionPiece)
-3. Named parameter approach: `addMove(from=..., to=..., promotionPiece=...)` triggers 4-param with castleSide default ✓
-4. Positional approach: `addMove(f, t, None, None)` requires all 4 args (explicit, no defaults used) - doesn't hit $default$4
-5. Root issue: Scala's overload resolution prefers more-specific non-default overloads (2-param, 3-param) over the 4-param with defaults
-
-**Recommendation:** 99.6% (1029/1033) is maximum achievable without refactoring method overloads. Unreachable code design patterns:
- **Pattern 1 (unreachable regex fallback):** Defensive pattern match against exhaustive regex
- **Pattern 2 (overshadowed defaults):** Method overloads shadow default parameters in parent signature
- **Pattern 3 (defensive catch-all):** Error handling for impossible external API returns
