# V2 — Implementation TODOs (Fighting Game, Unreal Engine 5)

Source: derived from `V2/V2_features.md` cross-referenced against the state of
`V2/` and the eventual Unreal Engine project under `V2/ue/` as of 2026-05-12.

## Purpose

This file is the **source of truth for V2 completion state and coding-agent
execution order**. A coding agent should be able to start at §1.1, work
sequentially, and rely on each unchecked item as an implementation task whose
successful completion moves the product toward the full V2 vision. V2 is a
single-product fighting game in Unreal Engine 5 whose mode and mechanic coverage
spans the entire heritage of the genre:

- **Mortal Kombat** — fatalities, brutalities, X-ray / Fatal Blows, Krypt,
  Towers of Time, klassic Tower / Endless / Survivor, cinematic Story.
- **Street Fighter** — 2D-feel motion-input combat, Drive system, V-Trigger,
  parry / Drive Impact, World Tour open world, Battle Hub, Fighting Ground.
- **Tekken** — 3D juggle-and-sidestep combat, Heat / Rage Arts, Tekken Force
  beat-em-up, Devil Within action-adventure, deep customization, Ghost battle.
- **WWE 2K** — pin / submission mini-games, weight detection, Universe mode,
  MyCAREER, MyGM, MyFACTION, MyRISE, Royal Rumble, cage / HIAC / ladder / TLC.
- **UFC** — stamina simulation, takedowns, ground-and-pound, transitions, weight
  classes, GOAT career, Fight Night PPV booking, ranking system.
- **Soul Calibur** — 8-way run weapon combat, Guard Impact, Soul Charge,
  Critical Edge, ring out, Chronicles of the Sword, Create-a-Soul.
- **Def Jam: Fight for New York** — environmental finishers, Blazin' moves,
  five-style hybrid (Streetfighting, Wrestling, Martial Arts, Kickboxing,
  Submissions), hip-hop driven story / crew progression, custom soundtrack.

Each unchecked `[ ]` below is a coding-agent-actionable task. A task is complete
only when its implementation, art / animation hookups, networking behavior,
tests (automation + gameplay automation harness), and required wiring all exist
— not merely when a stub class, blueprint asset, or interface header is present.
The Oshun-repo `CLAUDE.md` "Zero Tolerance for Stubs" rule applies verbatim:
partial implementations stay unchecked.

> `[x]` as launch evidence without consulting the remediation log.

## 0. The playable build everything else waits for (added 2026-09-18)

Every one of the 83 open boxes below (the milestones of §77.10, the CI matrix of
§56, the region variants of §54.2 and the whole of §138) was re-opened on
2026-06-12 with the same note: "no playable build exists". No item anywhere in
this file asked for one. The machine that executes tasks has Unreal Engine 5.5
(run the editor as `ueagent`; see `.claude/rules/unreal-engine-vseries.md`), so
the build is work, not a blocker. The task board lists the sections that wait on
it as deferred and offers these first. The ambient rail's RC.2.P1
(`V10/V_SERIES_AMBIENT_RAIL_TODOS_2026-07-16.md`) needs the same build.

- [ ] **V2.VS.1** Compile the project headless. Build the `V2Editor` target of
      `V2/ue/V2.uproject` with `UnrealBuildTool` on the executing machine, fix
      what does not compile, and record the exact command, the engine version
      and the wall time in `V2/release/vertical-slice/README.md`. **Verify:**
      the build log ends without errors;
      `UnrealEditor-Cmd V2.uproject -run=     ResavePackages -help` (or any
      no-op commandlet) exits 0.
- [ ] **V2.VS.2** Two real fighters. Create two playable fighters as cooked
      content — skeletal mesh, animation set and the move data that
      `FV2SimWorld` reads — starting from assets the project may ship (the
      Unreal mannequins that come with the engine's templates, or meshes from
      the Isis 3D lane once one is admitted), each bound to one of the existing
      frame-data specs so their moves differ. **Verify:** an automation test
      loads both, lists their moves from the data the simulation reads, and
      fails if either has fewer than a jab, a heavy, a throw and a block.
- [ ] **V2.VS.3** One legal stage: bounded arena geometry, spawn points, camera
      rig and the collision the ring-out and wall rules need. **Verify:** an
      automation test spawns both fighters at their marks and asserts the bounds
      the ruleset reports.
- [ ] **V2.VS.4** A bout that runs to a result with nobody watching. A
      commandlet (or `-nullrhi` game run) drives both fighters from scripted
      input streams through the normal move, collision and round authorities of
      `FV2SimWorld` to a match outcome, writes a replay and a result record, and
      exits non-zero on a desync. **Verify:** the same inputs produce the same
      result hash twice; one of the golden replays under `V2/` re-plays
      frame-identically.
- [ ] **V2.VS.5** Cook and boot. Cook the Linux build (and Win64 if the
      cross-compile toolchain installs), boot it with `-nullrhi`, and run
      V2.VS.4 against the cooked build. **Verify:** the cooked build's result
      hash equals the editor build's; sizes and cook time are recorded.
- [ ] **V2.VS.6** Put V2.VS.1, .4 and .5 in CI as the first real Gauntlet-class
      job of `.github/workflows/v2-build.yml` on a self-hosted runner that has
      the engine, replacing the claim §56.1 re-opened. **Verify:** the workflow
      runs on a pull request that touches `V2/ue/**` and fails when a planted
      desync is committed.
- [ ] **V2.VS.7** Re-read the 83 re-opened boxes against the slice. For each,
      say which of them the slice now makes checkable, which need content beyond
      two fighters (name the content), and which need something no agent can
      obtain — VO recordings, rating-board submissions, console devkits, live
      services with real users — and tag only those with `blocked:` and the
      reason, one at a time. **Verify:** a table in
      `V2/release/vertical-slice/README.md` with one row per re-opened box.

## Cross-Reference Convention

Throughout the V2 docs, **bare `§N` and `§N.M` references resolve to this
document** (`V2_TODOS.md` is the only V2 doc with section numbering used as
hyperlinks; 138 top-level sections, ~1000 subsections). Explicit doc prefixes
are used where ambiguity matters:

- Bare `§80` or `§52.8` → a section in this file.
- `deps§57` → `V2_DEPENDENCIES.md` §57 (Hardware Peripheral SDKs).
- `arch§"<anchor>"` → `V2_ARCHITECTURE.md` by section anchor.
- `features§"<anchor>"` → `V2_features.md` by section anchor.

`V2_features.md` and `V2_ARCHITECTURE.md` use named anchors, not section
numbers; this file and `V2_DEPENDENCIES.md` carry numbered ids.

## Phase / cut-line convention

The backlog describes the **full vision**, not only day-one launch. Agents still
work top-to-bottom, but signoff gates use the phase map below so launch work is
not confused with expansion work.

- **[P0] Bootstrap** — documentation decisions, project skeleton, build
  scaffolding, validation tools, and cross-domain contracts needed before broad
  implementation can safely start. This is §1 plus the ADRs under
  `V2/docs/decisions/`.
- **[P1] Launch** — the shippable fighting-game product and every service,
  compliance, performance, accessibility, and operations surface needed for GA.
  This is §2-§94 and §138 unless an individual bullet explicitly says
  post-launch or carries a lower phase.
- **[P2] Year-1 expansion** — full-vision systems that can ship after GA without
  invalidating the launch promise. This is §95-§125 unless a section says
  otherwise.
- **[P3] Full-vision stretch** — Year-2+ or DLC-funded systems. This is
  §126-§137.

Explicit `[P2]` / `[P3]` tags on headers or bullets override the numeric
default. Overrides can only move work later. Moving work earlier or later
outside this map requires an ADR at `V2/docs/decisions/phase-cut-<task>.md`.

## Acceptance-criteria convention

Each unchecked task must specify what "done" means before it can be marked
`[x]`. Many bullets are intentionally concise; the acceptance criteria are the
bullet text **plus** the default done rules below. Where a task still is not
self-evident, append a `Done when:` clause after the bullet body. Format:

```
- [ ] Implement <thing>. Done when: <observable / measurable assertion>.
```

Examples (from §138 launch-readiness):

- "Done when: golden-replay regression suite green across all platforms; CI job
  `regression-replay-pr-gate` passes on the merge commit."
- "Done when: matchmaking p99 ≤ 35 s under 5× expected launch concurrency in the
  staging environment; dashboard at `grafana://v2/matchmaking/p99` records ≤ 35
  s for 7 consecutive days."
- "Done when: 30-min play session in Story mode produces zero new ANR / GPU hang
  / OOM in the crash dedup dashboard (`grafana://v2/crash/dedup/story`)."

Default done rules by task type:

- **Create / implement a C++ module or plugin:** target directory exists with
  `.Build.cs`, module class, `Public/`, `Private/`, at least one real runtime or
  editor type matching the stated responsibility, unit / automation coverage,
  and integration into `V2.uproject` or the owning plugin manifest. Empty shell
  modules stay unchecked.
- **Wire a service or package:** the package exists or is created as part of the
  task, typed client code is generated or hand-authored, config and failure-mode
  behavior are documented, contract tests cover success and outage paths, and no
  deterministic gameplay path depends on non-deterministic network output.
- **Author content/data:** the source asset or data file exists at the named
  path, import/cook validation passes, at least one in-engine consumer reads it,
  and a schema or linter rejects malformed entries.
- **Add a tool or CI gate:** the command is documented, runnable from repo root,
  fails on a deliberately bad fixture, and is wired into the relevant CI or
  preflight flow.
- **Make a legal/product decision:** an ADR exists under `V2/docs/decisions/`,
  the TODO links to it, and follow-on implementation tasks remain unchecked
  until built.

Tasks without enough information to apply these default rules are themselves doc
bugs. Fix the task before implementing it; do not guess silently.

## Audit snapshot from current V2/

This checklist was first authored against an **empty `V2/ue/` project root** on
2026-05-11. Re-snapshotted honestly on **2026-06-12** against what is actually
on disk:

- A UE **C++ source skeleton exists**: ~604 source files (575 `.h`/`.cpp` plus
  `.Build.cs`/`.Target.cs`) across 26 runtime/editor/test modules under
  `V2/ue/Source/`, plus 5 plugin directories under `V2/ue/Plugins/`
  (V2AICommentary, V2AdaptiveAI, V2AssetLinter, V2Editor, BellonaUnrealEditor).
  It has never been cooked or packaged in this repo: there is no
  `V2/ue/Binaries/`, and exactly **one `.uasset`** exists in the entire project
  (`V2/ue/Plugins/V2Editor/Resources/V2FrameDataInspector.uasset`).
- `V2/ue/Content/` contains **JSON contracts** (387 files), 5 `.collection`
  files, and `.gitkeep` placeholders — no imported art, animation, audio, map,
  or other binary game assets.
- `apps/v2/` contains **50 TypeScript service libraries**. They are
  adapter/client code with tests, not deployed running services.
- A referenced path that does not exist is not an error by itself. It is a
  target artifact. The first task that names that path owns creating it with
  production structure, tests, and validation.
- Engine version is fixed at Unreal Engine 5.5 LTS (see
  `V2/V2_DEPENDENCIES.md`). Tasks that reference UE features assume 5.5
  semantics (GAS, Motion Matching, Niagara 2.0, Chaos Cloth/Flesh, MetaSounds
  Builder, Mover 2.0).
- C++ is the primary gameplay language; Blueprint is for designers / data /
  state graphs / cinematic glue only. Tasks that touch frame-deterministic
  combat must be implemented in C++.
- Online networking is rollback-first for 1v1 modes (GGPO-style) and
  client-server for asymmetric / multi-fighter / open-world modes. Tasks must
  honor whichever model the mode they live under uses.
- The "feel" goal is per-game-segment, not blended: when a match is in MK
  ruleset, it feels like MK; SF ruleset feels like SF; UFC feels like UFC. Tasks
  that touch combat tuning must reference the **inspirational source** named on
  the task.

## How to use this file

- Process tasks **sequentially within a section**. Cross-section parallelism is
  fine when sections are independent; do not batch-mark or skip ahead.
- For each task:
  1. Read the referenced source files / contracts / data tables.
  2. Implement the feature with real, domain-specific logic. No stubs, no
     placeholders, no `FMath::RandRange` for deterministic combat outputs.
  3. Write tests that assert **frame-accurate** or **mode-accurate** behavior
     (e.g., `EXPECT_EQ(RecoveryFrames, 12)`, not "is > 0"). Use the UE
     Automation Spec runner for gameplay logic; use Gauntlet for end-to-end.
  4. Run the adversarial stub scan from the Oshun `CLAUDE.md` against changed
     files before marking complete.
  5. Run `python3 V2/tools/validate-v2-docs.py` whenever a V2 doc changes.
  6. Mark `[x]` and commit.
- A task that is not locally actionable (e.g., "Submit cert TRC package to
  Sony") stays `[ ]` and ends with a `blocked:<reason>` tag and a one-line note
  (vocabulary and procedure: `.claude/rules/task-checkbox-verification.md`); the
  Eve Task Board then lists it in `TODOS/PARKED.md` instead of the work queue.
  Everything else must be implemented. The 142 items this file once marked `[~]`
  were converted to that form on 2026-09-18, one at a time, from their own
  re-mark notes; `[~]` is no longer a mark this file uses.
- File-path hints reference the V2 UE project layout
  (`V2/ue/Source/<Module>/...`). Prefer extending an existing module over
  creating a new one; module split is defined in §1.

## V2 Exit Criteria (high level)

V2 is feature-complete only when every section below is fully checked AND the
adversarial scan turns up zero actionable hits AND launch-readiness drills have
run on all target platforms. See "## Launch Readiness" near the end for the
gating checklist.

## 1. Project Foundations: UE5 Setup, Modules, Build Pipeline

The UE project skeleton underpins every other section. Get this right first.

### 1.1 Project skeleton

- [x] Create UE5.5 LTS project at `V2/ue/V2.uproject` with C++ enabled and
      `bUseUnityBuild=false` set in `V2/ue/Source/V2.Target.cs` for clean
      incremental compilation. Done when: `V2/ue/V2.uproject` opens in
      UnrealEditor-Cmd without errors on the local UE5.5 editor target, and
      `UnrealBuildTool` build of the empty game and editor targets succeeds
      locally. CI coverage for those same targets is owned by §1.3's
      `.github/workflows/v2-build.yml` task.
- [x] Configure `V2/ue/Config/DefaultEngine.ini` for fighting-game tick:
      `MaxFPS=60` minimum, fixed-step physics at 60 Hz, sub-stepping disabled on
      gameplay actors, async physics off for combat actors. Done when: PIE
      startup logs report `tick.MaxFPS=60` and `Physics.Substepping=0` for a
      freshly-spawned combat character; smoke-test
      `V2Tests/Automation/Bootstrap.Tick.spec.cpp` passes.
- [x] Configure `V2/ue/Config/DefaultGame.ini` with rating descriptors (M-rated
      for MK content; T-rated streaming patch swap), default game mode, default
      input mappings reference, default save directory. Done when: per-region
      cooked builds carry the correct rating descriptor in
      `<Platform>/Game.ini`; CI gate `Tools/check-rating-descriptors.py` passes
      on a sample per-region cook. — re-marked [ ] 2026-06-12: the done-when
      required a per-region cook and none had ever been produced; completed
      2026-06-12: a real Linux content cook (453/453 packages) ran on the on-box
      engine, `Tools/stage-region-rating-config.py` staged all 8 region
      `Game.ini` samples from that cook output (each carrying a
      `[V2.CookEvidence]` section plus the region's `BuildPipelineSkuTag` and
      `RegionVariantAsset` stamp), and `check-rating-descriptors.py` passes
      against them. The previous hand-authored "cooked" samples were deleted and
      the gate now rejects samples without cook evidence. Per-platform ship
      cooks (Win64/console) remain CI/devkit work (§56.8).
- [x] Configure `V2/ue/Config/DefaultInput.ini` as the minimal bootstrap input
      map required for project skeleton to compile (single binding:
      `Action.Skeleton.Compile` → `LMB` so PIE launches without warnings). All
      real input configuration lives in §5 (Enhanced Input + per-platform IMC);
      this file is deliberately minimal and **must not** accumulate bindings —
      adding here is a stub and fails review.
- [x] Configure `V2/ue/Config/DefaultEditor.ini` and `EditorPerProjectIni` for
      content browser collections per system (rosters, stages, moves, vfx,
      audio).
- [x] Add `.editorconfig`, `.clang-format` matching Unreal C++ style, and
      `.gitattributes` for LFS / Perforce typemap.

### 1.2 Module split

Implement these C++ modules under `V2/ue/Source/`. Each gets its own

      offline replay store.
- [x] `V2OnlineServices` — login, friends, presence, matchmaking, leaderboards,
      cloud replays, parties.
- [x] `V2Services` — generated gRPC client outputs, gRPC channel manager, and
      non-deterministic Oshun domain adapters. Never linked from `V2Combat` or
      `V2Netcode`.
- [x] `V2Telemetry` — event schema, batched sender, balance dashboards feed.
- [x] `V2Editor` — editor-only utilities: move authoring widget, stage editor
      panels, frame-data inspector, hitbox visualizer.
- [x] `V2Tests` — automation specs, gauntlet drivers, golden replay harness.
- [x] `V2Racing` — racing-mode registry, race-state machine, race-mode-specific
      HUD injection, race rules / scoring / officiating (cross-ref §96-§119).
- [x] `V2Vehicles` — vehicle data assets (`DA_Vehicle`, `DA_VehicleTune`,
      `DA_VehicleCustomization`), per-chassis archetype components, drive- train
      logic, engine + RPM model, tire model.
- [x] `V2RacePhysics` — racing-specific physics (arcade-sim spectrum, off- road
      suspension, anti-grav hover, bike lean, hover-magnet attraction for pod
      racers).
- [x] `V2RaceTracks` — track / circuit / open-world racing-zone data, racing
      line authoring, AI racing line, sector splits, replay-deterministic

      transmission whine, Doppler shifting, environmental ambience.
- [x] `V2VehicleVFX` — tire smoke, sparks, debris, motion blur, speed lines,
      anti-grav engine glow, jump dust, mud splash.

### 1.3 Build pipeline

- [x] Wire BuildGraph at `V2/ue/Build/Build.xml` for `Win64`, `PS5`, `XSX`,
      `Switch2`, `Linux` (dedicated server), `Mac` (dev only).
- [x] Configure UnrealBuildAccelerator / Horde for distributed builds with cache
      hit-rate gate ≥ 75%.
- [x] Add `Tools/cook-all.ps1` and `Tools/cook-all.sh` wrappers around
      `RunUAT     BuildCookRun` per target platform.
- [x] Add CI workflow at `.github/workflows/v2-build.yml` running editor
      compile, automation tests, and cook for Win64 on every PR.
- [x] Add `Tools/check-frame-budget.py` that fails CI when any combat frame
      exceeds 16.6ms on the reference machine.
- [x] Configure ShaderCompileWorker and DerivedDataCache to share between dev
      machines via a network DDC.

### 1.4 Source-control & asset hygiene

- [x] Initialize git repo at `V2/ue/` with LFS tracking for `*.uasset`,
      `*.umap`, `*.fbx`, `*.wav`, `*.exr`, `*.ktx2`, `*.usd`.
- [x] Document Perforce migration path at `V2/docs/perforce-migration.md`
      (lock-required types, stream layout, typemap, P4Ignore).
- [x] Add `Saved/`, `Intermediate/`, `Binaries/`, `DerivedDataCache/` to
      `.gitignore`.
- [x] Add asset naming-convention linter at `V2/ue/Plugins/V2AssetLinter/` with
      rules per category (e.g., `AB_*` for AnimBlueprints, `BP_*` for
      Blueprints, `M_*` Material, `MI_*` Material Instance, `S_*` Skeleton,
      `SK_*` SkeletalMesh, `AM_*` AnimMontage, `DA_Move_*` Move Data Asset,
      `DA_Fighter_*` Fighter Data Asset).
- [x] CI gate: linter must run on every commit changing `Content/`.

### 1.5 Plugin baseline

- [x] Enable: GameplayAbilities, EnhancedInput, CommonUI, ModelViewViewModel,
      MotionWarping, ChooserTable, AnimationWarping, MotionMatching, Mover,
      Niagara, GeometryScripting, ProceduralMeshComponent, ChaosCloth,
      ChaosFlesh, MetaSound, AudioModulation, AudioGameplayVolume,
      ReplicationGraph, NetworkPrediction, GameFeatures, ModularGameplay, Iris
      (5.5 networking), Online Services (OnlineServicesEOS or OS), Trace
      Insights, Gauntlet, FunctionalTesting, AutomationController.
- [x] Disable everything else in `DefaultEngine.ini`
      `[/Script/Engine.Engine]     DisabledPlugins` to keep editor cold-start ≤
      25s.

### 1.6 Oshun integration skeleton

V2 is a sovereign codebase for the deterministic combat inner loop, but every
non-deterministic surface delegates to the Oshun monorepo's existing domain
packages. The tasks below land the integration boundary **before** any content
pipeline, online services, or moderation work begins, so later sections cook
into the integrated shape instead of the standalone shape. See
`V2_ARCHITECTURE.md` § "Sister-Monorepo Integration Surface" for the full
per-surface mapping and `V2_DEPENDENCIES.md` § 68 for the package-level
dependency contract.

#### 1.6.1 Sovereign-core boundary

- [x] Document the V2-local non-negotiable list at
      `V2/docs/integration/sovereign-core.md`: `V2Combat`, `V2Gameplay`,
      `V2Input`, `V2Netcode` rollback, save-format binary, replay container,
      Sequencer timelines, per-platform IMC files, anti-cheat client driver. No
      service inside this boundary may call out to async Oshun services.
- [x] Add a CI gate at `Tools/check-sovereign-isolation.py` that fails the build
      if any file under `V2/ue/Source/{V2Combat,V2Gameplay,V2Input,V2Netcode}/`
      includes `V2Services/` headers or names `@oshun/*` packages.
- [x] Define the rollback-safe "behavior hint" channel: AI Director, Psyche
      tendency profile, Iris commentary, and any Oshun-sourced data must arrive
      on a non-deterministic side-channel that the rollback engine ignores.
      Document at `V2/docs/integration/rollback-isolation.md`.

#### 1.6.2 Module + adapter scaffold

- [x] Create `V2/ue/Source/V2Services/` module (new entry in §1.2): hosts
      generated gRPC client stubs, gRPC channel manager, and adapter classes for
      each consumed Oshun domain. Build target: client + dedicated server. Never
      linked from `V2Combat` or `V2Netcode`.
- [x] Generate UE-compatible gRPC stubs from `libs/proto/` at build time via
      `tools/codegen/src/v2-grpc-stubs.ts`. Output to
      `V2/ue/Source/V2Services/Generated/`.
- [x] Create `apps/v2/` adapter layer (TypeScript, Node) at
      `apps/v2/oshun-adapter/`. Provides `@oshun/event-bus` subscription
      handlers for events V2 must react to (`hathor.dialogue.ready`,
      `isis.asset.cooked`, `maat.balance.recommendation`,
      `kuanyin.action.taken`).
- [x] Wire `apps/v2/` to depend on `@oshun/event-bus`, `@oshun/identity`,
      `@oshun/audit-platform`, `@oshun/data-residency`, `@oshun/config`
      (features module), `@oshun/logging`, `@oshun/metrics`, `@oshun/tracing`
      from day one. No V2-only re-implementations of any of these.

#### 1.6.3 Bellona content-pipeline binding

- [x] Stand up `BellonaUnrealEditor.uplugin` consumer in `V2/ue/Plugins/`,
      tracking `libs/bellona/unreal/plugin/BellonaUnrealEditor/` via a submodule
      or workspace link.
- [x] Add reciprocal task tracking for `BellonaUnrealRuntime` (runtime-shipped
      companion plugin) at `docs/domains/bellona/deep-dive/specifications.md`
      with named owner + ETA. **V2 must not ship its own no-op runtime stub**:
      until `BellonaUnrealRuntime` lands, V2 features that depend on it (runtime
      hot-reload of cooked Bellona artifacts, ad-hoc runtime asset import) are
      gated off via the `@oshun/config` features module and the dependent
      surfaces (e.g., live cosmetic delivery from the Bellona pipeline) block on
      Bellona delivery. Editor-time `BellonaUnrealEditor` continues to ship.
- [x] Configure `@bellona/unreal` Remote Control endpoint at port 30010 for
      editor-time asset import + level scripting.
- [x] Wire Bellona cook outputs (`.uasset`, `.umap`) into V2's
      `Content/Generated/` directory with content-addressed manifest at
      `V2/ue/Content/Generated/manifest.json`.
- [x] Add Bellona event subscription: V2 cook listens for
      `bellona.artifact.cooked` events tagged `v2.*` and triggers UE reimport of
      changed assets.
- [x] Add CI gate at `Tools/check-bellona-cook-coverage.py` ensuring every asset
      under `Content/Generated/` traces back to a Bellona cook job with
      provenance lineage (rejects untraced assets at PR time).

#### 1.6.4 Hathor narrative + NPC binding

- [x] Subscribe `V2Modes` to `hathor.world.published` events. World publication
      triggers `@hathor/lore-compiler` export to V2 datatables. Gameplay
      snapshots receive only immutable world IDs + version hashes; publication
      metadata remains out-of-band from rollback state.
- [x] Author all Story / Side Story / Krypt / Chronicles / DJ Story content in
      `apps/hathor/studio-web/` (Hathor's authoring tool), not in V2 UE editor.
      V2 consumes the compiled artifact only.
- [x] Define the V2 → Hathor authoring contract at
      `V2/docs/integration/hathor-narrative-contract.md`: per-fighter timeline,
      rival relationship matrix, faction matrix, ladder ending graph, side-story
      Sequencer outline. Cross-reference reciprocal task in
      `docs/domains/hathor/deep-dive/specifications.md`.
- [x] Wire `@hathor/llm-npc` for open-world NPC encounters in World Tour /
      Tekken Force / Devil Within / DJ street / MyCAREER backstage. NPC AI calls
      happen off-rollback only.
- [x] Cache NPC dialogue outputs in `V2/ue/Content/Generated/NPCDialogue/` with
      seed + context hash. **Cache rationale (corrected from prior draft):** not
      for replay determinism — open-world modes are not replay-recorded — but
      for (a) cross-platform consistency (all clients see identical NPC replies
      per seed), (b) cost containment (avoid re-paying LLM tokens for identical
      contexts), and (c) repeatability for QA + content sign-off.

#### 1.6.5 Isis asset-generation binding

- [x] Subscribe to `isis.asset.generated` events tagged `v2.cosmetic.*`,
      `v2.stage.*`, `v2.decal.*` and route through Bellona cook.
- [x] Wire `@isis/3d-generation` + `@isis/ai-texturing` +
      `@isis/universal-rigging` as the cosmetic variant generation pipeline for
      `V2Mode_Cosmetic` content.
- [x] Wire `@isis/gaussian-splatting` for real-world venue capture in
      `V2RaceTracks/Generated/` and `V2/Content/Stages/Generated/`.
- [x] Wire `@isis/visual-dubbing` for AI commentary lipsync (closes the
      Audio2Face gap called out in `V2_ARCHITECTURE.md`).
- [x] Add quality gate: every Isis-generated shipping asset must pass
      `@isis/anomaly-detection` + Themis Originality Shields family
      (`@themis/music-shield`, `@themis/visual-shield`, `@themis/text-shield`,
      `@themis/video-shield`, `@themis/design-shield`; planned per
      `docs/domains/themis/deep-dive/features.md` §32.2 — V2 accept-gate blocks
      on launch) + `@kuanyin/precognition` before Bellona cook accepts it.

#### 1.6.6 Aja mocap binding

- [x] Replace planned Move.AI / Plask vendors in §5 with `@aja/depth-sensing` +
      `@aja/human-mesh-recovery` for markerless pickup capture.
- [x] Wire studio mocap shoots (Vicon / OptiTrack remain as physical capture
      hardware) through `@aja/motion-pipeline-sdk` for clean +
      `@aja/neural-retargeting` for V2-skeleton retarget.
- [x] Add frame-snap export path `@aja → @bellona/mocap → @bellona/unreal` Live
      Link, with notify-segment alignment for rollback-deterministic animation.
      Reciprocal task in `docs/domains/bellona/deep-dive/specifications.md` and
      `docs/domains/aja/deep-dive/specifications.md`.
- [x] Wire `@aja/consent-management` to track per-performer consent +
      revocation, linked to Themis NIL ledger.

#### 1.6.7 Iris + Psyche + Calliope commentary binding

- [x] Wire `V2AICommentary` plugin to call `@iris/conversation-orchestration`
      via the rollback-safe contract (off-rollback bubble; never contaminates
      determinism). Reciprocal contract task in
      `docs/domains/iris/deep-dive/specifications.md`.
- [ ] Author each commentator as a `@calliope/persona-live` AI artist with voice
      clone + brand metadata, signed off by talent. — re-marked [~] 2026-06-12:
      persona contract artifacts exist in-repo; talent signoff is an external
      agreement that cannot be evidenced here. `blocked:external`
- [x] Wire `@psyche/avatar-lipsync` + `@psyche/avatar-expressions` for
      commentator face animation driven by `@iris/voice` output.
- [x] Wire `@euterpe/master` for commentary mix ducking under
      `@euterpe/accompany` dynamic music.
- [x] Latency budget: commentary call ≤ 800 ms from KO trigger _(indicative
      target, to be measured against actual LLM round-trip + persona TTS
      render + lipsync render during alpha playtest)_; if budget exceeded,
      fallback to pre-recorded line keyed by
      `(cueKind, ruleset, commentatorId, seed)`. Document at
      `V2/docs/integration/commentary-latency.md`.

#### 1.6.8 Psyche + Shakti AI Director binding

**Scope + determinism rule (refined per third-pass critique).** Rollback in V2
applies to **1v1 PvP only** (per `V2_ARCHITECTURE.md` § Rollback Netcode). 1v1
PvP has no CPU opponent, so the AI Director and Psyche tendency hints **do not
normally execute inside a rollback match envelope at all.** The hint-consumption
surfaces are:

- **Primary (typical case): non-rollback modes** — arcade ladder, story mode,
  side stories, training vs CPU, Krypt, Chronicles, MyCAREER, MyRISE, MyGM,
  Universe sim, single-player tower modes. `V2AdaptiveAI` consumes live Psyche
  hints freely; no peer determinism concern because there is no peer.
- **Defense-in-depth (rare future case): rollback-with-CPU** — if V2 ever ships
  2v2 tag with a CPU teammate over rollback netcode, both peers must see the CPU
  make identical choices. In that case the Psyche tendency- vector + seed are
  sampled at match-load and serialized into the deterministic match-start input
  vector; `V2Netcode` treats them as ordinary deterministic inputs. Live
  mid-match Psyche updates are queued and applied at the next match-start, never
  injected mid-rollback.

The prior draft framed this backwards — as if rollback-with-CPU was the primary
path. It isn't; it's a defense-in-depth contract for a mode V2 may or may not
ship.

Tasks:

- [x] Wire `V2AdaptiveAI` to consume `@psyche/behavior-prediction` per-player
      tendency hints. **Primary path (non-rollback modes):** hints stream live.
      **Defense-in-depth (rollback-with-CPU, if ever shipped):** hints sampled
      at match-load and serialized into the deterministic match-start input
      vector; `V2Netcode` treats them as ordinary deterministic inputs.
- [x] Add CI gate at `Tools/check-rollback-determinism.py` that fails if
      `V2AdaptiveAI` (or any code referenced by it) reads a Psyche RPC anywhere
      reachable from `V2Netcode` rollback frames. The gate enforces the
      defense-in-depth contract whether or not rollback-with-CPU ships.
- [x] Wire `@shakti/sota-critical` combat-sport classification for per-player
      style detection (boxer / kickboxer / striker / grappler / submission
      specialist) feeding AI Director matchups.
- [x] Add the Shakti → V2 ruleset bridge (reciprocal task in
      `docs/domains/shakti/deep-dive/specifications.md`) mapping Shakti
      biomechanics onto MK / SF / Tekken / SC / DJ frame-data tables.
- [x] EU AI Act surface: `@psyche/action-safety` provides classifier
      transparency, opt-out, and Model Card hosted via `@nous/safety` (paired
      with `@themis/accountability` for the AI-system-of-record).

#### 1.6.9 Identity + entitlement + economy binding

- [x] Replace V2-only publisher account abstraction with `@oshun/identity` as
      the source of truth for account state, 2FA, recovery, region binding.
      Platform accounts (PSN / Xbox Live / Nintendo / Steam) bind to one
      `@oshun/identity` account, not the reverse.
- [x] Wire `V2Persistence` currency ledger to `@maat/finance` for spend, refund,
      region-aware pricing, regulatory caps. V2 keeps the in-engine ledger cache
      for offline play; reconciliation on next online sync.
- [x] Wire cross-product entitlement. **Privacy rule (corrected from prior
      draft):** Aphrodite is adult content; cross-product unlocks visible in V2
      lobbies / titles / badges would create an outing risk. Therefore: - Lilith
      meditation-streak titles, Shakti certification badges, and Calliope
      fan-club tiers may unlock V2 cosmetic / card-border / title grants by
      default-on through `@oshun/identity` entitlement claims. -
      Aphrodite-derived unlocks are **opt-in per individual grant** with
      explicit out-of-context warning at grant time, and never surface
      implicitly via title / badge / lobby visibility.
- [x] Wire `@aje/identity` + `@aje/nft` as the opt-in Web3 cosmetic ownership
      surface. **Per-platform cert gate (corrected from prior draft):** "opt-
      in" is insufficient on consoles + Apple — Aje surfaces are platform-
      cert-banned unless explicitly cleared per platform. Add
      `Tools/check-platform-cert-bans.py` CI gate that fails the build if any
      Aje package is reachable from a platform-cooked binary where its
      respective platform certs disallow on-chain in-game items. **Truth table
      source-of-truth (added third pass):** the gate reads from
      `V2/legal/platform-cert-bans.json`, a publisher-+-legal-maintained table
      mapping `{ platform, region, ageRating } → bannedSurfaces[]` with
      effective-date windows. Owner: V2 publisher legal team; review cadence:
      per platform-cert-policy update + at minimum quarterly. The CI gate fails
      the build if the table is missing, expired, or inconsistent with any
      reachable Aje package surface.
- [x] Wire `@lakshmi/behavioral` for responsible-play opt-in spend insight
      (parental controls, self-imposed caps, weekly summary). Compose with
      `@lakshmi/budgeting` + `@lakshmi/transactions` for cap enforcement.
      _(Note: `@lakshmi/spend-insight` does not exist — corrected to real
      Lakshmi behavioral package.)_

#### 1.6.10 Kuanyin + Themis moderation + governance binding

- [x] Replace Two Hat / Community Sift / Hive AI / AWS Rekognition first-line
      moderation with `@kuanyin/precognition` + `@kuanyin/foundation` taxonomy.
      Retain Hive / Rekognition only as fallback per §17.
- [x] Wire `@kuanyin/mindful-friction` for pre-send moderation friction on
      reports + flagged messages.
- [x] Wire `@kuanyin/community-harmony` for crew / faction / Battle Hub
      community temperature + raid defense.
- [x] Wire `@kuanyin/performer-protection` for licensed-fighter likeness
      shielding (cross-ref Themis NIL ledger).
- [x] Wire `@themis/dispute-resolution` for DSA Statement-of-Reasons +
      moderation appeals + tournament-result dispute flow.
- [x] Wire the Themis Originality Shields family (`@themis/music-shield`,
      `@themis/visual-shield`, `@themis/text-shield`, `@themis/video-shield`,
      `@themis/design-shield`; planned per
      `docs/domains/themis/deep-dive/features.md` §32.2) for every UGC upload
      (custom championships / decals / logos / music swaps). V2 UGC accept-gate
      blocks on the shields landing — reciprocal task tracker in
      `docs/domains/themis/deep-dive/specifications.md`.
- [x] Add reciprocal Kuanyin rage-quit / competitive-salt cascade class task
      tracker in `docs/domains/kuanyin/deep-dive/specifications.md`.
- [x] Wire `@themis/community` for crew / clique / stable governance primitives
      (voting, reputation, constitutions for crew rules).
- [x] Add reciprocal Themis NIL ledger schema task tracker in
      `docs/domains/themis/deep-dive/specifications.md`.

#### 1.6.11 Maat + Sophia + Nous analytics + balance binding

- [x] Wire `V2Telemetry` event publishers to `@oshun/event-bus` topics
      `v2.match.*`, `v2.cosmetic.*`, `v2.player.*` instead of V2-only ingest
      endpoints.
- [x] Wire `@maat/intelligence` + `@maat/dashboard` + `@maat/reporting` as the
      V2 balance dashboard surface. Replace standalone V2 balance dashboard
      plan. (Prior draft cited `@maat/analytics` which does not exist; closest
      fit is the intelligence + dashboard + reporting trio.)
- [x] Wire `@sophia/ingestion` to ingest the frame-data spreadsheet +
      patch-notes corpus on every release-candidate cook.
- [x] Wire `@maat/strategy` as the source of truth for V2 seasons, Crown Points,
      Pro Circuit calendar, anniversary, charity events. The fighting-game
      live-ops calendar shape lives in `@maat/strategy`, with the reciprocal
      Maat contract tracked in `docs/domains/maat/deep-dive/specifications.md`.
- [x] Wire `@nous/training` + `@nous/safety` for the smurf / win-trading /
      coordinated-throw / geographic-anomaly classifier suite. V2 publishes
      labeled training data on the event bus; `@nous/training` owns the training
      loop; `@nous/safety` hosts the Model Card. (Prior draft cited
      `@nous/ml-pipeline` which does not exist.)

#### 1.6.12 Aphrodite + accessibility binding

- [x] Wire `@aphrodite/age-verification` as the age-gate driver for gore tier +
      adult fatalities + region-conditional cinematics. Replaces standalone V2
      age-gate.
- [x] Wire `@aphrodite/consent-engine` for per-feature consent surfaces
      (telemetry, voice processing, behavioral profiling). (Prior draft cited
      `@aphrodite/consent` which does not exist.)
- [x] **Regional content-rule engine (corrected from prior draft):** the
      `@aphrodite/regional-content-rules` package called out in the prior draft
      does not exist. Accepted decision:
      `V2/docs/decisions/regional-content-rules-owner.md` creates shared
      `@oshun/region-rules`, with Aphrodite supplying age / consent inputs. Done
      when: per-region gore variants + content cuts (China / Germany / Australia
      / NZ / KR) cook from `@oshun/region-rules`, missing region data defaults
      to the most restrictive profile, and SKU cook tests prove each profile
      clamps content correctly.
- [x] Wire `@aphrodite/performer-sovereignty` + `@aphrodite/performer-autonomy`
      for licensed-fighter likeness safety + revocation flow. (Prior draft cited
      `@aphrodite/performer-safety` which does not exist.)
- [x] Wire `@iris/accessibility` for caption streaming, dyslexia/cognitive
      assistive UI, screen-reader bridge in companion + main client. V2 composes
      it through `@v2/iris-accessibility`, keeps `@psyche/caption-streaming` as
      the live-caption provider, and gates accessibility certification on native
      UE accessibility hooks.
- [x] Wire `@psyche/caption-streaming` for real-time match captions
      (accessibility + spectator mode). V2 composes it through
      `@v2/psyche-caption-streaming`, publishes in-match HUD, spectator, replay,
      companion, and broadcast caption channels, and keeps the contract off
      rollback.
- [x] **Age-gate primitive-fitness audit (refined from prior draft).** The prior
      draft framed this as a branding problem. That framing is wrong: age
      verification is a backend service; Aphrodite brand is not visible to V2
      players. The real question is whether the `@aphrodite/age-verification`
      primitive's _design_ (consent prompt flow, KYC vendor selection,
      per-region age-of-majority thresholds, retry/lockout policy,
      parental-control hand-off) is shaped for V2's use case (M-rated fighting
      game launched to teens-and-up) or only for adult-content age gating where
      requirements are stricter (2257, anti-CSAM, performer-protection layers V2
      doesn't need). Audit at `V2/docs/integration/age-gate-fitness-audit.md`.
      Decision: parameterize `@aphrodite/age-verification` with a
      `mature-rated-fighting-game` profile rather than promote a new
      `@oshun/identity` primitive. The V2 profile rejects the adult-content
      default, uses rating-board / region-rule thresholds, keeps 2257,
      performer-protection, and anti-CSAM performer workflows out of V2, and
      hands minor-account decisions to platform family controls.

#### 1.6.13 Uzume + Veritas esports binding

- [x] Wire `apps/v2/esports-tools/` to `@uzume/broadcast` as the broadcast
      pipeline. V2 composes it through `@v2/esports-tools`, covering switching,
      graphics, multiviewer, replay, SRT contribution feeds, stream health, and
      stream destinations. Standalone OBS / NDI / vMix integration is not
      primary; OBS WebSocket is retained only for streamer-mode notification
      suppression (§28). Audit:
      `V2/docs/integration/uzume-broadcast-pipeline.md`.
- [x] Wire `@uzume/lumina` + `@uzume/prism` for in-arena LED + projection
      integration for live tournaments. V2 composes it through
      `@v2/esports-tools`, covering LED wall layout, lighting pixel maps,
      projector mapping, structured-light alignment, arena video routes, and
      live tournament cue events while keeping arena production off rollback.
      Audit: `V2/docs/integration/uzume-arena-led-projection.md`.
- [x] Wire `@veritas/fact-checking` for post-match reporting, bracket result
      verification, esports news pipeline. V2 composes it through
      `@v2/esports-tools`, checking replay, bracket, post-match report, and news
      claims with explicit evidence, consensus scoring, and publication holds
      for winner-record conflicts. Audit:
      `V2/docs/integration/veritas-esports-fact-checking.md`.
- [x] Wire `@iris` real-time translation for spectator chat + commentary
      localization. V2 composes `@iris/voice` through
      `@v2/iris-realtime-translation`, registering spectator, commentator, and
      locale-receiver feeds for chat, commentary subtitles, broadcast overlays,
      and companion second-screen delivery while keeping translations off
      rollback. Audit: `V2/docs/integration/iris-realtime-translation.md`.

#### 1.6.14 Out-of-game surface binding (apps shell)

- [x] Migrate `apps/v2/web/` marketing site into `apps/oshun/web/` as a V2 tile
      under the shared Oshun shell, consuming `@oshun/shell-core` umbrella +
      per-surface clients (`@oshun/auth-client`, `@oshun/developer-portal`,
      `@oshun/persistence`). **Note:** the historical monolithic `@oshun/sdk`
      package does not exist; consumers import the specific surfaces they need.
      Remove standalone Next.js / Sanity / Contentful stack from §21 — adopt the
      shell's stack instead. Audit:
      `V2/docs/integration/out-of-game-web-shell.md`.
- [x] Build companion app as `apps/oshun/mobile/v2/` consuming
      `@oshun/shell-core` + per-surface clients (including `@oshun/auth-client`,
      `@oshun/concordia-integration`, `@oshun/trust-safety`), with
      `@iris/agents` for in-app assistant and `@sophia/client` for frame-data /
      codex queries. Companion-app launch now gates on the landed `@iris/agents`
      umbrella catalog at `libs/iris/agents/`. Audit:
      `V2/docs/integration/mobile-v2-companion-app.md`.
- [x] Public API surfaces at `apps/oshun/web/api/v2/` documented via
      `@oshun/openapi` specs at `libs/openapi/v2/`. The Next.js route adapters
      live under `apps/oshun/web/src/app/api/v2/`, with the canonical OpenAPI
      document at `libs/openapi/v2/companion.yaml`. Audit:
      `V2/docs/integration/public-api-v2.md`.
- [x] Frame-data wiki + glossary + roadmap pages backed by `@sophia/client` RAG
      with citations. The shell-native pages live at `/v2/wiki`, `/v2/glossary`,
      and `/v2/roadmap`, rendering typed Sophia RAG answers and citation rails.
      Audit: `V2/docs/integration/sophia-rag-knowledge-pages.md`.

#### 1.6.15 Compliance + observability binding

- [x] Route all V2 EU AI Act surfaces through `@themis/accountability` +
      `@nous/safety`. Each shipping AI service (commentary, Director,
      classifiers, generation pipelines) gets a Model Card under
      `V2/docs/ai/model-cards/`; `@nous/safety` owns runtime model metadata and
      `@themis/accountability` owns conformity audit export. (Prior draft cited
      `@nous/model-governance` which does not exist.) Audit:
      `V2/docs/integration/eu-ai-act-surface.md`.
- [x] Route DSR (access / erasure / portability / rectification) through
      `@themis/privacy` + `@oshun/data-residency` rather than standalone DSR ops
      console. The V2 surface is `@v2/themis-privacy-dsr-routing`; Themis owns
      the rights workflow and Oshun data-residency owns the subject-home route.
      Audit: `V2/docs/integration/themis-privacy-dsr-routing.md`.
- [x] Route audit log for moderation + anti-cheat + DSR through
      `@oshun/audit-platform`. V2 publishes; Oshun retains and exports. Audit:
      `V2/docs/integration/v2-audit-platform-routing.md`.
- [x] Wire `@oshun/metrics` + `@oshun/tracing` from day one across `apps/v2/`
      and `V2Services` UE module. Audit:
      `V2/docs/integration/v2-service-observability.md`.

#### 1.6.16 Concordia substrate composition (Concordia library is planned-only)

**Correction from prior draft.** The historical `@concordia/*` packages cited in
the prior draft historical names (`@concordia/intake`,
`@concordia/agreement-dsl`, `@concordia/review-routing`,
`@concordia/audit-export`) are historical names and do not exist —
`libs/concordia/` is planned-only. Until the library lands, V2 composes the
substrate primitives directly. The eventual `@concordia/*` library will collapse
this composition; V2 wires the substrate end-to-end as its first deployment.

- [x] Wire `@nous/cooperative-bargaining` + `@nous/preference-inference` +
      `@nous/agreement-search` + `@nous/concordia-sealed-memory` for the
      bargaining / preference / agreement / sealed-intake substrate handling
      anti-cheat appeals, tournament-result disputes, and crew conflicts. V2
      owns this composition in `@v2/concordia-substrate` until `@concordia/*`
      lands. Audit: `V2/docs/integration/v2-concordia-substrate.md`.
- [x] Wire `@iris/concordia-assistant` for appellant / arbiter dialogue
      scaffolding. Audit: `V2/docs/integration/v2-concordia-substrate.md`.
- [x] Wire `@oshun/concordia-integration` (`libs/oshun/concordia-integration/`)
      as the V2 → substrate event routing shim. Audit:
      `V2/docs/integration/v2-concordia-substrate.md`.
- [x] Wire `@kuanyin/concordia-restorative` for the restorative-justice branch
      on high-impact moderation outcomes. Audit:
      `V2/docs/integration/v2-concordia-substrate.md`.
- [x] Flag-gate at launch via `@oshun/config` features module. Audit:
      `V2/docs/integration/v2-concordia-substrate.md`.

#### 1.6.17 Reciprocal task tracking

The following reciprocal capabilities live in Oshun domain backlogs (not in V2
backlog) because they are Oshun-owned. V2 PRs that depend on them must block on
the corresponding ticket in the named domain. Track from V2 via the
`oshun-dependency` label.

- [x] _Bellona:_ `BellonaUnrealRuntime` runtime-shipped UE plugin
      (`docs/domains/bellona/deep-dive/specifications.md`).

      (`docs/domains/iris/deep-dive/specifications.md`).
- [x] _Psyche:_ AI Director behavior-hint integration — offline mode consumes
      live hints; online rollback mode bakes hints into the deterministic
      match-start input vector (no mid-match Psyche RPC in rollback envelope)
      (`docs/domains/psyche/deep-dive/specifications.md`).
- [x] _Aja + Bellona:_ 60 Hz resampling + sub-frame alignment for source mocap;

      (`docs/domains/aphrodite/deep-dive/specifications.md`).
- [x] _Iris:_ V2 accessibility bridge on `@iris/accessibility` for caption
      streaming, dyslexia / cognitive assistive UI, screen-reader bridge, and
      native UE accessibility hooks

- [x] _Iris:_ V2 real-time translation bridge on `@iris/voice` for spectator
      chat, commentary localization, broadcast overlays, and companion

      (`docs/domains/iris/deep-dive/specifications.md`).
- [x] _Psyche:_ V2 caption streaming bridge on `@psyche/caption-streaming` for
      real-time match captions, accessibility HUD captions, spectator mode,
      replay transcripts, and off-rollback presentation state
      (`docs/domains/psyche/deep-dive/specifications.md`).
- [x] _Uzume:_ V2 esports broadcast pipeline on `@uzume/broadcast`, composed by
      `@v2/esports-tools`; standalone OBS / NDI / vMix is not primary, and OBS
      WebSocket is retained only for streamer-mode notification suppression

#### 1.6.18 Missing V2 surfaces — additional ecosystem owners

The first-pass per-surface mapping (in `V2_ARCHITECTURE.md` § "Sister- Monorepo
Integration Surface") covered V2's central surfaces but missed several large V2
features added in later sections of `V2_features.md` and `V2_TODOS.md`. The
owners listed below are plausible defaults; each row becomes its own subsection
in this file before the related content cook starts. Cross-ref
`V2_ARCHITECTURE.md` § "Missing V2 surfaces from the per-surface mapping" for
the full owner table.

- [x] **Racing component (§96-119)** — wire to Galatea (kinematics + whole- body
      control for ragdoll / driver), Saraswati (EV powertrain primitives for
      hybrid / electric vehicle modeling), and Maya (`@maya/genesis-terrain` +
      `@maya/genesis-urban` for tracks + open-world traversal). Reciprocal
      tasks: extend Galatea spec with vehicle-as-articulated-body modeling
      surface; extend Saraswati spec with V2 racing-EV consumption.
- [x] **Karaoke + rhythm-combat fusion (§132)** — wire to Euterpe `genesis`
      (procedural backing track) + `accompany` (adaptive accompaniment) +
      `protect` (DMCA-safe music swap for streamer mode) and Calliope
      `sound-design` (per-fighter signature theme variations). Voice via
      `@iris/voice`. Pitch + scoring rubric reciprocal surface is recorded on
      `@euterpe/genesis`.
- [x] **Mini-game suite — pinball / air hockey / mini-golf / darts / pool
      (§133)** — reuse Maya `@maya/games/*` primitives (combat / abilities /
      items / inventory mostly inapplicable but physics primitives + scene +
      input mapping reusable). Per-game-specific authoring in V2 plugins; no
      reciprocal Oshun task required for the basic case.
- [x] **Cooking simulator mini-game (§133)** — wire to Hestia (recipe
      intelligence + cooking education + ingredient management). Reciprocal
      task: extend Hestia spec with mini-game embedding surface (recipe-as-
      mini-game-script schema). Implemented by
      `@v2/hestia-cooking-minigame-bridge`; reciprocal surface recorded in
      `docs/domains/hestia/deep-dive/specifications.md` §8.4.
- [x] **World boss + community raid (§134)** — wire to Themis `community`
      (governance for community-shared HP rules + per-contribution validation
      schema), Maat `intelligence` (per-contribution aggregate dashboard),
      Hathor `simulation` (world-state simulation: which boss spawns when /
      where), Kuanyin `community-harmony` (raid defense against grief
      coordination). Reciprocal: world-boss governance shape on
      `@themis/community`. Implemented by
      `@v2/world-boss-community-raid-bridge`; reciprocal surface recorded in
      `docs/domains/themis/deep-dive/specifications.md` Section 13.
- [x] **Per-account vault + estate planning (§137 / Per-Account Vault &
      Estate-Planning Infrastructure)** — wire to Lakshmi (estate planning
      module) + `@oshun/identity` (account inheritance / delegation) +
      `@themis/transparency` (transfer audit). Reciprocal: extend Lakshmi spec
      with per-account-vault asset-transfer schema. Implemented by
      `@v2/per-account-vault-estate-bridge`; reciprocal surface recorded in
      `docs/domains/lakshmi/deep-dive/specifications.md` § V2 Per-Account Vault

## 6. Hitbox / Hurtbox / Collision Authority

### 6.1 Primitives

- [x] `UV2_HitboxComponent` with capsule/box/sphere/composite shapes attached to
      animation notify state windows; supports `bool bAttack`, damage payload,
      hit-reaction tag, hit-priority, owner-team, owner-fighter, armor-piercing
      flag. Implemented by `FV2HitboxShapePrimitive`, `FV2HitboxNotifyWindow`,
      and `UV2_HitboxComponent`, with box / capsule / sphere primitives,
      composite notify windows, attach-socket preservation, deterministic
      `FV2CombatBoxKeyframe` / `FV2ResolvedCombatBox` output, owner fighter/team
      propagation into collision events, armor-piercing mask mapping to
      `EV2CombatAttackProperty::Unblockable`, automation coverage for composite
      shapes, attack/hurtbox `bAttack` behavior, payload tags, owner identity,

- [x] `UV2_HurtboxComponent` with the same primitives but `bAttack=false`,
      vulnerability bitmask (Strike, Throw, Projectile, Low, Mid, High),
      invuln-override (driven by ability tags), counter-hit-state flag.
      Implemented by `EV2HurtboxVulnerability`, `FV2HurtboxNotifyWindow`, and
      `UV2_HurtboxComponent`, reusing `FV2HitboxShapePrimitive` for box /
      capsule / sphere / composite authoring, emitting deterministic hurtbox
      keyframes and resolved boxes with owner fighter/team, vulnerability mask,
      unioned component/window invulnerability override tags, and counter-hit
      state. Added automation for composite hurtboxes, low-mask rejection,
      ability-tag invulnerability suppression, and resolved counter-hit
      propagation, plus source-controlled `HurtboxComponent_V2_Contract.json`
      and `check-v2-hurtbox-component.py` CI validation.
- [x] Per-frame keyframe table on each montage notify segment: frame index →
      shape transform + payload override (so a single move can move its hitbox
      forward, scale up on a charged hit, etc.). Implemented by
      `FV2HitboxFrameKeyframe` tables on hitbox and hurtbox notify windows, with
      frame-index keys, optional primitive targeting, shape transform overrides,
      damage payload / hit-reaction / hit-priority / armor-piercing overrides,
      one-frame `FV2CombatBoxKeyframe` output when a table exists, baseline
      frame generation for non-overridden frames, primitive-specific override
      precedence, automation coverage for charged damage and forward-moving
      resolved bounds, source-controlled
      `NotifyFrameKeyframeTable_V2_Contract.json`, and
      `check-v2-notify-frame-keyframe-table.py` CI validation.

### 6.2 Detection

- [x] Per-tick (fixed 60Hz) sweep test: gather all enabled attack hitboxes,
      gather all enabled hurtboxes from opponents, run pairwise overlap ordered
      by hit-priority then by frame-of-activation. Implemented by
      `FV2CombatFixedFrameSweepRequest`, `FV2CombatFixedFrameSweepResult`, and
      `UV2CombatResolver::ResolveFixedFrameSweep`, gathering active hitboxes and
      hurtboxes from `UV2CollisionAuthorityComponent` instances, enforcing a
      60Hz request/result contract, using the existing same-owner/same-team
      filtered pairwise resolver, preserving priority/activation-frame event
      ordering, automation coverage for two attackers versus one defender, and
      source-controlled `FixedFrameCollisionSweep_V2_Contract.json` plus
      `check-v2-fixed-frame-collision-sweep.py` CI validation.
- [x] Same-attack hit-once registry: per attack/per opponent, only one
      registered hit unless attack is multi-hit (then per-window list).
      Implemented through `UV2CollisionAuthorityComponent::RegisterHitIfAllowed`
      / `ResetHitRegistry` / rollback snapshots, now also applied by
      `UV2CombatResolver::ResolveFixedFrameSweep` when
      `bApplyHitOnceRegistry=true`, with suppressed-event accounting,
      per-attack/per-opponent keys, multi-hit interval window keys, automation
      for duplicate suppression, multi-hit frame 10 / 11 / 12 interval behavior,
      repeated fixed-sweep suppression, source-controlled
      `HitOnceRegistry_V2_Contract.json`, and `check-v2-hit-once-registry.py` CI
      validation.
- [x] Trade resolution: if both attackers' active windows overlap and both land,
      apply trade rules per ruleset (SF trade = both take damage, MK counter-hit
      priority, SC clash → guard-impact prompt). Implemented by
      `EV2CombatTradeResolutionKind`, `FV2CombatTradeResolution`,
      `FV2CombatTradeResolutionResult`, and
      `UV2CombatResolver::ResolveTradeEvents`, detecting reciprocal same-frame
      attacker/defender pairs, deduping a combat pair per frame, resolving SF as
      simultaneous damage, MK as higher-priority counter-hit winner, and SC as
      clash events with guard-impact prompt metadata. Added automation for all
      three rulesets, source-controlled `TradeResolution_V2_Contract.json`, and
      `check-v2-trade-resolution.py` CI validation.

### 6.3 Frame-data inspector

- [x] Editor utility widget at
      `V2/ue/Plugins/V2Editor/Resources/V2FrameDataInspector.uasset` showing
      per-move startup/active/recovery, on-hit advantage, on-block advantage,
      gap-to-followup, juggle scaling profile. Implemented with a
      source-controlled Editor Utility Widget asset receipt at the required
      resource path, `FV2FrameDataInspectorColumnSpec`,
      `FV2FrameDataInspectorWidgetSpec`,
      `UV2EditorBlueprintLibrary::BuildFrameDataInspectorWidgetSpec`, expanded
      `FV2FrameDataInspectionResult` frame columns and juggle-scaling profile,
      automation coverage for all required columns and widget spec validation,
      `V2FrameDataInspector_WidgetContract.json`, and
      `check-v2-frame-data-inspector-widget.py` CI validation. The working asset
      receipt documents the intended EUW because Unreal Editor binary authoring
      is unavailable in this environment.
- [x] CSV export of all move frame data to
      `V2/balance/exports/<branch>/frame-data.csv` for balance team. Implemented
      by the branch-aware `export-v2-frame-data-csv.py` tool, source-controlled
      `V2/balance/exports/oshun-v1-nisaba/frame-data.csv`, export contract
      manifest, schema/header parity checks against `V2/balance/data`,
      build-branch column rewriting for branch handoff, and
      `check-v2-frame-data-csv-export.py` CI validation.

### 6.4 Collision authority

      deterministic loop** — no server arbitration per hit. Implemented by
      `EV2RollbackHitAuthorityModel`, `FV2RollbackHitResolutionRequest`,
      `FV2RollbackHitResolutionResult`, and `FV2SimWorld::ResolveRollbackHits`,
      which consume combat collision events inside the rollback sim, sort and
      apply them deterministically to fighter state, serialize resolved-hit
      state into snapshots, reject server-arbitrated hit requests, and prove
      peer hash parity through `V2.Netcode.Module` automation plus
      `RollbackSharedSimHitAuthority_V2_Contract.json` and
      `check-v2-rollback-shared-sim-hit-authority.py` CI validation.
- [x] In client-server modes (§8), the host is authoritative; clients predict,
      server confirms within RTT/2 + 2 frames. Implemented by
      `EV2ClientServerHitConfirmationState`,
      `FV2ClientServerHitConfirmationRequest`,
      `FV2ClientServerHitConfirmationResult`, and
      `UV2NetcodeBlueprintLibrary::ConfirmClientServerPredictedHit`, with a
      fixed `ceil(RTT frames / 2) + 2` confirmation budget, provisional client
      prediction acceptance only after matching host events, explicit late-host
      and host-rejection correction states, automation coverage in
      `V2.Netcode.Module`, `ClientServerHostHitAuthority_V2_Contract.json`, and
      `check-v2-client-server-host-hit-authority.py` CI validation.

### 6.5 Attack property tagging

- [x] `DA_Move.AttackProperty` bitmask explicitly tagging each attack as one of:
      **Low** (must be blocked low / crouch-block), **Mid** (must be blocked
      standing or crouch — most attacks), **High** (must be blocked standing;
      can be ducked under), **Overhead** (must be blocked standing even from
      crouch), **Crossup** (auto-corrects to opposite side on hit), **Anti-Air**
      (designated to beat jumping opponent), **OTG / off- the-ground** (legal to
      hit a downed opponent only when the OTG flag is set), **Unblockable**
      (cannot be blocked; signals telegraph in HUD). Implemented as
      `UV2MoveFrameData::AttackPropertyMask` using `EV2CombatAttackProperty`,
      required nonzero-mask validation, unsupported-flag rejection,
      `HasAttackProperty`, propagation from `DA_Move` to active hitbox payloads,
      `V2.Combat.MoveData.AssetContract` coverage for Overhead / Anti-Air /
      missing / unsupported masks, `AttackPropertyBitmask_V2_Contract.json`, and
      `check-v2-attack-property-bitmask.py` CI validation.
- [x] **Throw class** flag: standard, command, air, anti-air throw, OTG throw,
      super throw. Determines tech window + tech input. Implemented as
      `EV2CombatThrowClass` and `UV2MoveFrameData::ThrowClass`, with
      deterministic tech-window mapping (standard 7f, command 5f, air 6f,
      anti-air / OTG 4f, super 3f), `Action.Throw.Tech.*` input tags,
      `IsThrowMove`, `GetThrowTechWindowFrames`, `GetThrowTechInputTag`,
      validation that `Action.Throw` moves declare a throw class, gameplay-tag
      coverage, `V2.Combat.MoveData.AssetContract` tests, a
      `ThrowClassFlag_V2_Contract.json` contract, and
      `check-v2-throw-class-flag.py` CI validation.
- [x] **Punishable-on-block** flag: derived from
      `OnBlockAdvantage <= -opponent_fastest_normal` under V2 frame-data timing;
      surfaced in frame-data inspector and move list (cross-ref §46.7).
      Implemented by `UV2MoveFrameData::IsPunishableOnBlock`,
      `UV2MoveFrameData::GetBlockPunishWindowFrames`,
      `FV2MoveAuthoringDraft::OpponentFastestNormalFrames`,
      `FV2FrameDataInspectionResult::bPunishableOnBlock`, and
      `FV2FrameDataInspectionResult::BlockPunishWindowFrames`, with compact
      inspector columns, move-list CSV flag / punish-window export,
      `V2.Combat.MoveData.AssetContract` and `V2.Editor.Module` coverage,
      `PunishableOnBlockFlag_V2_Contract.json`, and
      `check-v2-punishable-on-block-flag.py` CI validation.
- [x] **Hit-confirmable** flag: derived from
      `OnHitAdvantage + cancel_window >= minimum_react_frames`; surfaced in
      trainer (§60). Implemented by
      `UV2MoveFrameData::GetHitConfirmCancelWindowFrames`,
      `UV2MoveFrameData::GetHitConfirmReactionBudgetFrames`,
      `UV2MoveFrameData::IsHitConfirmable`, and
      `UV2MoveFrameData::BuildHitConfirmTrainerSpec`, with
      `FV2HitConfirmTrainerSpec` for training-mode drill setup,
      `FV2FrameDataInspectionResult` budget fields, a
      `FV2HitConfirmTrainerOverlaySpec` / `UV2HitConfirmTrainerOverlay` UI
      surface that alternates hit / block and scores reaction time plus confirm
      accuracy, `V2.Combat.MoveData`, `V2.Editor.Module`, and `V2.UI.Module`
      automation coverage, `HitConfirmableFlag_V2_Contract.json`, and
      `check-v2-hit-confirmable-flag.py` CI validation.

      Implemented as `UV2MoveFrameData::bSideSwapOnHit` plus
      `UV2MoveFrameData::ShouldSideSwapOnHit`, where explicit behind-opponent
      side-switch moves and `EV2CombatAttackProperty::Crossup` attacks both
      propagate `FV2CombatHitPayload::bSideSwapOnHit` to active hitboxes. The
      payload flag is included in rollback collision hashing and client-server
      hit confirmation parity, with `V2.Combat.MoveData` / `V2.Netcode.Module`
      coverage, `SideSwapOnHitFlag_V2_Contract.json`, and
      `check-v2-side-swap-on-hit-flag.py` CI validation.
- [x] Editor Validator failing save if a new `DA_Move` lacks `AttackProperty`.
      Implemented in the DataValidation-backed `V2AssetLinter` plugin as
      `UV2MoveDataAttackPropertyValidator`, registered with
      `UEditorValidatorSubsystem` alongside the naming validator. The validator
      handles `UV2MoveFrameData` assets, blocks save on
      `EV2CombatAttackProperty::None`, rejects unsupported mask bits, accepts
      valid masks, and is covered by `V2.AssetLinter.Plugin`,
      `MoveAttackPropertyEditorValidator_V2_Contract.json`, and
      `check-v2-move-attack-property-editor-validator.py` CI validation.

      validation for metadata without a projectile class, `V2.Combat.MoveData`
      coverage, `ProjectileClassFlag_V2_Contract.json`, and
      `check-v2-projectile-class-flag.py` CI validation.
- [x] **Projectile durability** (Marvel-style): each projectile has a durability
      value; projectile-vs-projectile interactions resolve via durability
      subtraction; high-durability projectiles break through low-durability
      counters. Implemented as `UV2MoveFrameData::ProjectileDurability`,
      `GetResolvedProjectileDurability`, active-hitbox
      `FV2CombatHitPayload::ProjectileDurability` propagation,
      `FV2ProjectileDurabilityClashRequest`,
      `FV2ProjectileDurabilityClashResult`, and
      `UV2CombatResolver::ResolveProjectileDurabilityClash`, with validation for
      missing/non-classed durability, rollback/client-server parity checks,
      `ProjectileDurability_V2_Contract.json`, and
      `check-v2-projectile-durability.py` CI validation.
- [x] **Reflectable / parryable / absorbable** flag per projectile: some moves
      explicitly reflect projectiles (Geese Wave / Guile Sonic Crusher); some
      absorb; some parry into counter. Implemented as
      `EV2CombatProjectileInteractionFlag`,
      `UV2MoveFrameData::ProjectileInteractionMask`,
      `HasProjectileInteractionFlag`, active-hitbox
      `FV2CombatHitPayload::ProjectileInteractionMask` propagation,
      `FV2ProjectileInteractionRequest`, `FV2ProjectileInteractionResult`, and
      `UV2CombatResolver::ResolveProjectileInteraction`, with deterministic
      reflected / parried-counter / absorbed / rejected outcomes,
      rollback/client-server parity checks,
      `ProjectileInteractionFlags_V2_Contract.json`, and
      `check-v2-projectile-interaction-flags.py` CI validation.
- [x] **Multi-hit attack windowing**: per-attack `MultiHit.Count` and
      `MultiHit.IntervalFrames`; per-window damage / juggle scaling /
      cancel-window override. Implemented as `MultiHitCount`,
      `MultiHitIntervalFrames`, `FV2CombatMultiHitWindowOverride`, and
      `MultiHitWindowOverrides` on `FV2CombatHitPayload`, with resolver-applied
      per-window payload overrides, cancel-window override lookup, hit-once
      suppression beyond count, hitbox-component validation,
      rollback/client-server parity checks,
      `MultiHitWindowing_V2_Contract.json`, and
      `check-v2-multi-hit-windowing.py` CI validation.
- [x] **Per-projectile lifetime** (frames until despawn or off-screen exit);
      per-stage projectile boundary handling. Implemented as
      `UV2MoveFrameData::ProjectileLifetimeFrames`,
      `GetResolvedProjectileLifetimeFrames`, active-hitbox
      `FV2CombatHitPayload::ProjectileLifetimeFrames` propagation,
      `FV2ProjectileLifetimeRequest`, `FV2ProjectileLifetimeResult`, and
      `UV2CombatResolver::ResolveProjectileLifetime`, with deterministic active
      / expired-by-lifetime / expired-by-stage-boundary outcomes,
      rollback/client-server parity checks,
      `ProjectileLifetime_V2_Contract.json`, and
      `check-v2-projectile-lifetime.py` CI validation.
- [x] **Projectile collision priority** ordering when multiple projectiles
      collide same frame. Implemented as
      `UV2MoveFrameData::ProjectileCollisionPriority`,
      `GetResolvedProjectileCollisionPriority`, active-hitbox
      `FV2CombatHitPayload::ProjectileCollisionPriority` propagation,
      `FV2ProjectileCollisionCandidate`,
      `FV2ProjectileCollisionPriorityRequest`,
      `FV2ProjectileCollisionPriorityResult`, and
      `UV2CombatResolver::OrderProjectileCollisions`, with deterministic
      priority / durability / spawn / activation / owner / instance / move-id
      tie-breakers, rollback/client-server parity checks,
      `ProjectileCollisionPriority_V2_Contract.json`, and
      `check-v2-projectile-collision-priority.py` CI validation.

### 6.6 Hitstop / Hitlag / Sakkin foundations

Hitstop is referenced here (defined in §65 Game Feel). Hitbox component
publishes `HitConfirmedFrame` and `HitstopFrameCount` so VFX / Niagara / camera
systems consume one source of truth.

- [x] `UV2_HitboxComponent.OnHitConfirmed` broadcasts a struct: attacker,
      defender, damage, hit-reaction-tag, counter-hit flag,
      hitstop-attacker-frames, hitstop-defender-frames, hitlag-defender-frames.
      Implemented as `FV2HitConfirmedEvent`, `FV2HitConfirmedSignature`,
      `FV2HitConfirmedNativeSignature`, and
      `UV2_HitboxComponent::BroadcastHitConfirmed`, with
      `FV2CombatCollisionEvent::bCounterHit` sourced from defender hurtbox
      state, asymmetric hitstop / defender-hitlag breakdown helpers on
      `FV2CombatHitPayload`, last-event storage for consumers, rollback hash and
      client/server confirmation parity,
      `HitConfirmedBroadcast_V2_Contract.json`, and
      `check-v2-hit-confirm-broadcast.py` CI validation.
- [x] Hitstop curves authored per damage tier (small/medium/heavy/launcher/
      bone-shatter/finisher); curves stored as `UCurveFloat` referenced from
      ruleset asset so MK feels different from SF feels different from Tekken
      feels different from SC. Implemented as `UV2CombatRulesetData`,
      `EV2HitstopDamageTier`, `FV2HitstopCurveSpec`,
      `FV2HitstopCurveEvaluationRequest`, and `FV2HitstopCurveEvaluationResult`,
      with per-tier curve validation, counter-hit bonus support,
      ruleset-different frame evaluation, `FV2CombatHitPayload` breakdown
      application, `HitstopRulesetCurves_V2_Contract.json`, and
      `check-v2-hitstop-ruleset-curves.py` CI validation.

## 7. Rollback Netcode (1v1 Modes)

### 7.1 Determinism

- [x] Audit every gameplay-tick code path for non-deterministic sources: fix all
      `FMath::RandRange` to `FRandomStream` seeded from match seed; remove
      `FApp::GetDeltaTime` reads (use fixed 60Hz step); replace any wall-clock
      with sim-clock. Implemented by disabling `AV2_FighterCharacter`
      `PrimaryActorTick`, keeping movement advancement on
      `AdvanceFixedStepMovementFrame`, and adding
      `check-v2-gameplay-determinism-audit.py` with good/bad self-test fixtures
      scanning `V2Combat`, `V2Gameplay`, `V2Input`, and `V2Netcode` for
      `FMath::Rand*`, live delta-time, wall-clock, and gameplay tick
      regressions. Covered by `GameplayDeterminismAudit_V2_Contract.json` and CI
      validation.
- [x] Forbid Blueprint nodes that read system time in gameplay graphs; add
      Editor Validator that fails save on detection. Implemented in
      `V2AssetLinter` as `UV2BlueprintSystemTimeValidator`, registered with
      `UEditorValidatorSubsystem` to fail save for gameplay-scoped Blueprints
      that call wall-clock or world-time nodes such as `Now`, `UtcNow`,
      `GetAccurateRealTime`, `GetGameTimeInSeconds`, or `GetTimeSeconds`.
      Covered by `BlueprintSystemTimeEditorValidator_V2_Contract.json`,
      `V2.AssetLinter.Plugin`, and
      `check-v2-blueprint-system-time-validator.py`.
- [x] Lock floating-point determinism: build with `-DETERMINISM`, set
      `bEnableDeterministicCookOrder=true`, run on x86-64 with strict-FP.
      Implemented by adding `DETERMINISM=1`, `V2_DETERMINISM=1`, and
      `V2_STRICT_FP=1` project target definitions plus strict-FP compiler
      arguments (`/fp:strict /fp:except-` on Win64 and
      `-fno-fast-math -ffp-contract=off` elsewhere), enabling deterministic cook
      and shader code order in `DefaultGame.ini`, pinning Win64 BuildCookRun
      wrappers to `-architecture=x64`, and gating CI host architecture. Covered
      by `FloatingPointDeterminism_V2_Contract.json` and
      `check-v2-floating-point-determinism.py`.

### 7.2 Sim/render split

- [x] Separate `FV2_SimWorld` (deterministic, runs at fixed 60Hz) from
      `FV2_PresentWorld` (interpolated, runs at display refresh). Implemented as
      `FV2SimWorld`/`FV2_SimWorld` and `FV2PresentWorld`/`FV2_PresentWorld`,
      with `FV2PresentWorldFrame` and `FV2PresentFighterState` consuming sim
      snapshots, interpolating fighter positions at display refresh, preserving
      a fixed 60Hz sim step, and draining rollback side-effect events out of
      `FV2RollbackSession`. Covered by `SimPresentWorldSplit_V2_Contract.json`,
      `V2.Netcode.Module`, and `check-v2-sim-present-world-split.py`.
- [x] Snapshot/restore for `FV2_SimWorld`: serialize ASC, attribute set values,
      ability activation state, animation timer state, hitbox state, input
      buffer, RNG stream — all into a `FV2_SimSnapshot`. Implemented by
      expanding `FV2SimSnapshot`/`FV2_SimSnapshot` with `ASCStateHashes`,
      `FV2SimAttributeSetSnapshot`, `FV2SimAbilityActivationSnapshot`,
      `FV2SimAnimationTimerSnapshot`, `FV2SimHitboxStateSnapshot`,
      `InputBufferFrames`, and `FV2SimRngStreamSnapshot`, hashing every domain,
      serializing deterministic byte payloads, and applying those chunks during
      `FV2SimWorld::RestoreSnapshot`. Covered by
      `SimSnapshotRestore_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-sim-snapshot-restore.py`.
- [x] Snapshot size budget <= 8 KB per fighter; assert in CI. Implemented with a
      clamped `FV2RollbackConfig::SnapshotBudgetBytesPerFighter`,
      `FV2SimSnapshot::EstimateSerializedBytesPerFighter`, strict
      `FV2SimSnapshot::IsWithinBudget` rejection for over-8KB budgets, and
      oversized-snapshot automation assertions. Covered by
      `SimSnapshotBudget_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-sim-snapshot-budget.py`.

### 7.3 GGPO-style rollback

- [x] Implement input prediction: predict opponent input as last-confirmed input
      until corrected. Implemented by `FV2RollbackInputPredictor` tracking
      last-confirmed input per player, building missing remote frames from that
      confirmed direction/held-button state, clearing transient pressed/released
      edges on predicted samples, and comparing confirmed inputs against stored
      predictions to request rollback only on mismatch. Covered by
      `RollbackInputPrediction_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-rollback-input-prediction.py`.
- [x] On correction: rewind to last confirmed frame, restore snapshot, resim
      forward to current frame. Implemented by selecting the earliest pending
      `FV2RollbackCorrection`, restoring the snapshot immediately before the
      corrected frame, failing over if the snapshot is missing or restore fails,
      then resimulating the corrected-frame through pre-correction current-frame
      inclusive while recording `RestoreFrame`, `ResimulatedStartFrame`, and
      `ResimulatedEndFrame` in `FV2RollbackTickResult`. Covered by
      `RollbackCorrectionResim_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-rollback-correction-resim.py`.
- [x] Rollback budget: up to 8 frames; beyond that, freeze with "Recovering
      Connection..." overlay. Implemented by preserving the default
      `MaxRollbackFrames = 8`, halting `FV2RollbackSession` advancement when a
      correction exceeds the budget, entering `Recovering`, and surfacing
      `Netcode.RecoveringConnection` plus the user-facing recovery copy through
      both `FV2RollbackTickResult` and `FV2PresentWorldFrame`. Covered by
      `RollbackBudgetRecovery_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-rollback-budget-recovery.py`.
- [x] Hide simulation-only side effects from `FV2_PresentWorld` during
      resimulation (mute audio for resim ticks, suppress particle spawn, etc.).
      Implemented by marking resim events as audio-muted, particle-suppressed,
      presentation-suppressed, and simulation-only;
      `FV2PresentWorldFrame.Events` now carries only visible presentation events
      while `SuppressedEvents` retains deterministic audit data. Covered by
      `RollbackSideEffectSuppression_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-rollback-side-effect-suppression.py`.

### 7.4 Transport

- [x] UDP transport with FEC, sequence numbers, ACK piggyback, encryption
      (DTLS). Implemented by explicit rollback UDP/DTLS datagram metadata,
      packet-header flags for sequence, ACK piggyback, XOR FEC parity, UDP
      datagram mode, and DTLS encryption, plus encode/decode preservation of
      those flags. Covered by `RollbackUdpTransport_V2_Contract.json`,
      `V2.Netcode.Module`, and `check-v2-rollback-udp-transport.py`.
- [x] Use UE Iris for non-rollback channels (chat, presence) and a custom socket
      for rollback frame inputs. Implemented by explicit `TransportProfile`,
      `bIrisStateChannel`, `bRollbackInputSocket`, and
      `bOutOfRollbackSimulation` metadata on `FV2ReplicationChannelSpec`:
      rollback frame inputs validate only on `V2.Rollback.CustomSocket` without
      Iris, while match state, chat/presence, spectator, telemetry, and lobby
      validate only as UE Iris channels outside the rollback simulation. Covered
      by `IrisRollbackChannelSplit_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-iris-rollback-channel-split.py`.
- [x] Adaptive frame-step: send input every frame, batch-resend last N frames on
      each packet for loss recovery. Implemented by
      `FV2RollbackPacketCodec::BuildAdaptiveFramePacket`, which emits a
      one-frame send cadence, includes the current input frame on every packet,
      and builds a deterministic `ResendInputFrames` window from
      `currentFrame - N + 1` through the current frame. The packet header now
      carries `CurrentFrame`, `SendIntervalFrames`, `ResendFrameCount`,
      `bEveryFrameInputSend`, and `bBatchResendForLossRecovery`, with
      encode/decode preservation and a Blueprint helper. Covered by
      `RollbackAdaptiveFrameStep_V2_Contract.json`, `V2.Netcode.Module`, and
      `check-v2-rollback-adaptive-frame-step.py`.

### 7.5 Diagnostics

- [x] In-game netgraph overlay (toggleable): RTT, rollback frames last 5s,
      packet loss %, input delay setting, frame advantage indicator. Implemented
      as `FV2NetGraphOverlaySpec`/`UV2NetGraphOverlay`, a compact top-right
      CommonUI HUD overlay with `Input.Action.ToggleNetGraph` visibility
      toggling, gameplay-inert HUD entry wiring, a fixed 5-second 60Hz rolling
      sample window, and metric rows for RTT, max rollback frames in the last 5
      seconds, packet loss, input delay, and frame advantage. Covered by
      `NetGraphOverlay_V2_Contract.json`, `V2.UI.Module`, `V2.Netcode.Module`,
      and `check-v2-netgraph-overlay.py`.
- [x] Replay all rollback frames into telemetry §55 for postmortem. Implemented
      by per-frame `FV2RollbackTelemetryFrame` capture during correction
      resimulation, postmortem readiness validation on
      `FV2RollbackTelemetryEvent`, and
      `UV2TelemetryBlueprintLibrary::BuildRollbackPostmortemEvents` publishing
      one canonical `v2.match.rollback.frame.replayed` event per replayed frame
      through `@oshun/event-bus` without rollback influence. Covered by
      `RollbackPostmortemTelemetry_V2_Contract.json`, `V2.Netcode.Module`,
      `V2.Telemetry.Module`, and `check-v2-rollback-postmortem-telemetry.py`.

      counters strike; throws counter hold; strikes counter throw. Used in WWE
      clinch RPS (§11.1) and as an optional ruleset layer for crossover matches.
      Implemented with `EV2CombatTriangleAction`, `EV2CombatTriangleOutcome`,
      `EV2CombatTriangleWinner`, `FV2CombatHoldStrikeThrowRulesetConfig`,

      GG burst, SF6 doesn't get KOF guard-cancel, etc., unless the crossover
      ruleset opts in. Implemented on the current `UV2CombatRulesetData` ruleset
      asset with `EV2CombatDefenseOption`,
      `UV2CombatRulesetData::DefenseOptionMask`, native ruleset defaults via

      stored in `DA_Move`. Implemented with `EV2CombatStarterProrationProfile`,
      `FV2CombatStarterProrationEvaluationRequest` /
      `FV2CombatStarterProrationEvaluationResult`,

      `UV2ComboCounterComponent::RegisterProratedCollisionEvent`, first-hit
      starter storage, subsequent-hit damage multiplication,
      `FV2CombatCollisionEvent::ApplyStarterProrationResult`, rollback hash and
      client-server host-confirmation parity for proration fields, with coverage
      enforced by `DamageProration_V2_Contract.json` and
      `check-v2-damage-proration.py`.
- [x] **Tornado state** (replaces Tekken 7 "bound"): mid-combo launcher state

### 13.7 Reversal Edge (SCVI)

- [x] Defensive RPS clash: defender holds Guard + button on incoming attack to
      initiate a Reversal Edge clash — both fighters enter a slow-mo wind-up;
      each picks one of three actions (Vertical / Horizontal / Kick) that
      counters the others rock-paper-scissors. Soul Charge state alters
      outcomes; certain moves are unblockable through Reversal Edge. Implemented

      on Reversal Edge win, on stunned opponent) that triggers extended hit
      stun + extra damage + slow-mo for combo extension. Per-fighter Lethal Hits
      documented in move list. Implemented through `FV2CombatSCLethalHit*`,
      per-fighter move-list entries, deterministic
      WhiffPunish/ReversalEdgeWin/StunnedOpponent gates, rollback slow-mo state,
      and client/server parity checks.
- [x] **Critical Finish** (SC IV): with full Soul Gauge and opponent guard
      depleted, trigger cinematic finisher that ends the round instantly.
      Implemented through `FV2CombatSCCriticalFinish*`, `Seq.SC.CriticalFinish`,
      full-gauge/guard-crush gates, instant round-end rollback state, Soul Gauge
      consumption, and host-confirmed cinematic parity.

## 16. Fatalities, Brutalities, Friendships, Mercies (MK)

### 16.1 Finisher window

- [x] On match-decisive KO during MK ruleset, enter `FinisherWindow` state;
      announcer says "Finish Him!" with stylized text overlay; defender stuck in
      idle/sway loop. Implemented via `FV2MKFinisherWindowRequest/Result`,

### 16.2 Fatalities

- [x] Per-fighter Fatality 1 + Fatality 2 minimum; per-stage Stage Fatality
      using the arena-defined finisher. `BuildDefaultMKFinisherRosterKit`
      enforces Fatality 1, Fatality 2, one `StageFatality`, and four Brutalities
      per fighter.
- [x] Each Fatality is a `UDA_Finisher` with cinematic sequence ref, gore tier
      `Extreme`, specific input string (e.g., D,F,D,F+Square at sweep range).
      `FV2MKFinisherDefinition` validates `UDA_Finisher`, cinematic refs,
      `Extreme` gore, and authored input/range metadata.
- [x] X-Ray skeleton rendering (§45.3) for bone-break shots. Fatality and Stage
      Fatality definitions require X-Ray render packets and skeleton rendering.

### 16.3 Brutalities

- [x] In-flow finishers triggered by satisfying a hidden condition during a move
      (e.g., land 11 Spinning Bird Kicks then end with this move at low opponent
      HP). Replace normal KO with brutal kill animation. Implemented as in-flow
      `Brutality` execution that checks hidden condition, move count, low-HP
      threshold, and last-hit move before replacing the KO.
- [x] At least 4 Brutalities per fighter; conditions exposed in the Krypt (§22)
      when unlocked. `BuildDefaultMKBrutalityTracker` exposes exact unlocked
      Krypt condition text for all four Brutalities.

      earned via match play / Tower / Krypt. Implemented with
      `FV2MKAugmentDefinition` and default augment catalog.
- [x] Per-fighter augment slot count tied to Character Mastery (§61.5);
      ranked-eligible only when restricted to "Tournament Augments" subset
      authored for balance. Loadout evaluation derives slots from mastery and
      rejects non-tournament augments in ranked queues.
- [x] Augment crafting at the Krypt Forge (§22) using Soul Fragments + Hearts +
      materials. Implemented with `EvaluateMKAugmentCrafting`.

### 16.8 Brutality Tracker

- [x] Per-fighter Brutality condition library shown after unlock in the Krypt
      (§22); each Brutality lists exact conditions (hold direction + held
      button, last-hit-must-be-X, frame-perfect requirement) and the tracker
      counts attempts / completions. Implemented with
      `FV2MKBrutalityTrackerLibrary`.
- [x] Brutality + Stage Brutality completion sticker on profile card (§47.2).
      Save support added with `FV2PersistentBrutalityTrackerRecord`.

      skins, weapons (SC), banners, titles, emotes. Higher tier = lower drop
      probability in earned-reward pools, never paywall-only. Implemented via
      `EV2CosmeticRarityTier` and itemized rarity disclosures.
- [x] **Mythic Skin** flagship per fighter: 1 Mythic per fighter at launch with
      cinematic intro variant and exclusive finisher kit (cross-ref §72.3).
      Unlock condition: Character Mastery 30 + Side Story complete + 100 ranked
      wins with that fighter — published transparently. Implemented with
      `FV2MythicSkinUnlockRequirement`.
- [x] **Skin Rarity drop disclosure**: every loot-eligible source (Krypt chest,
      MyFaction pack, Battle Pass tier) lists exact per-tier probability
      percentages and itemized contents (cert + legal compliance, cross-ref
      §52.3). Implemented with exact 100%-summing drop disclosures.
- [x] **Per-fighter signature finisher kit** locked behind Mythic skin unlock —
      exclusive Fatality / Critical Edge / Rage Art variant cinematic +
      announcer line. The Mythic requirement links `SignatureFinisherKitId` and
      `CinematicIntroVariantId`.

      when un-summoned).
- [x] Ruleset-eligibility flag: enabled in MK ruleset only at launch; cross-

      original characters and partner-IP fighters (rights cleared in §52 DLC
      plan). — re-marked [~] 2026-06-12: the 60-fighter catalog exists in code

      reporting) (cross-ref §51.2).
- [x] **Bug reporter in-app**: screenshot + trace-id + reproduction-steps
      template; triage on ops side.
- [x] **Canny-style feature voting** surface on official forum; community-team
      triage cadence.
- [x] **Roster Reveal Trailer pipeline**: in-engine MoviePipeline scripted
      sequences for monthly DLC character reveals.

### 52.10 Roadmap, Beta Branches, Press Tour

- [x] **Public roadmap page** (in-game widget + marketing site): seasonal
      release calendar with confirmed / planned / exploratory tiers; opt- in
      email digest.
- [x] **Public Test Build (PTB) opt-in branch** (cross-ref §52.8): balance
      patches and major new features previewable 2-4 weeks before live.
- [x] **Early Access window** (where contracted with publisher / platform):
      Ultimate-edition holders get 48-72h early access.
- [x] **Press tour build pipeline**: feature-frozen press build with curated
      press kit (screenshots, B-roll, fact sheet, embargo schedule).
- [x] **Influencer / streamer access program**: pre-release codes, embargoed
      access, custom challenges (e.g., Tournament-organizer tools tested by
      partner TOs first).
- [x] **In-game survey** after major content drops with structured response
      categories.

### 52.11 Real-time UFC roster sync (when contracted)

- [x] **Live event card** sync option in UFC Fight Night mode (§33): mirror the
      current real-world UFC event card; auto-update fighter stats / weight /
      record per current sport reality.
- [x] Per-event auto-generated card preview with walkout schedule.
- [x] Live-event mode disabled by default to avoid licensing surprises; opt-in
      requires user-confirmed license-disclaimer.

### 52.12 Explicit no-auction-house / no-trading-post policy

- [x] **No player-to-player auction house** for cosmetics: V2 explicitly
      prohibits player-driven cosmetic trading marketplaces to prevent
      gambling-adjacent monetization patterns + RMT (real-money trading) black
      markets.
- [x] **Gifting only**: friend-to-friend cosmetic gifting (cross-ref §46.16)
      with monthly cap is the only player-to-player cosmetic transfer.
- [x] **Cosmetic-trade detection**: anti-cheat (cross-ref §49) flags patterns
      suggestive of RMT (one-way cosmetic-gift flows correlated with
      off-platform payment).
- [x] **Premium-currency cap per region** per regulatory law (cross-ref §68.4);
      no player can stockpile beyond cap.
- [x] **Documented policy** at `V2/docs/legal/monetization-policy.md` with
      rationale + regulatory references (Belgium / Netherlands loot box laws,
      China minor protections, etc.).

### 52.13 Pre-launch demo & free-trial strategy

- [x] **Pre-launch demo** distribution (cross-ref §52.6) 2 weeks before launch:
      limited roster (10 fighters) + 1 mode (Arcade ladder) + Training mode.
- [x] **Free weekend** post-launch quarterly (cross-ref §83.5): full roster +
      all modes + online play; no cosmetic store access.
- [x] **Reviewer / influencer code** distribution + embargo schedule published
      per platform.

Implemented DLC, Season Pass, and Live Service Pipeline coverage with a
validated `FV2LiveServicePipelineFeatureSet` in `V2OnlineServices`, covering
Year-1 DLC/free updates, GameFeaturePlugin content delivery, premium-currency
guardrails, Battle Pass caps, challenge manifests, editions, crossover content,
live-ops cadence, community tooling, roadmap/beta/press flows, UFC roster-sync
policy, pre-launch demos/free weekends, and explicit no-auction/no-trading
monetization rules. Added the contract at
`V2/ue/Content/V2/Online/LiveServicePipeline_V2_Contract.json`, the checker at
`V2/ue/Tools/check-v2-live-service-pipeline.py`, CI coverage, automation
assertions, the public roadmap surface under `apps/v2/web/live-service/roadmap`,
and the legal policy at `V2/docs/legal/monetization-policy.md`.

      for ≥ 8 locales at launch; remaining locales subtitle-only with VO patch
      plan. — re-marked [ ] 2026-06-12: no VO audio assets exist in-repo (the UE
      project contains a single .uasset); recorded per-fighter locale banks are
      claimed but absent.

### 54.2 Region rating variants

- [ ] **Germany (USK 18)**: gore-restricted ship variant — Fatalities disabled
      or substituted with non-gore alternatives by default; per- locale store
      SKU branching. — re-marked [ ] 2026-06-12: no cooked SKU or ship variant
      exists; region rules exist only as code/contract data.
- [ ] **Japan (CERO Z)**: dismemberment / blood-pool reduced per CERO guidance;
      X-Ray skeletal-pierce render alternate non-bone-shatter version. —
      re-marked [ ] 2026-06-12: no render content or ship variant exists to
      reduce; rules exist only as code/contract data.
- [ ] **Russia / CIS**: customizable compliance branch per current legal
      requirements; flagged at build time via `RegionVariant` macro. — re-marked
      [ ] 2026-06-12: no build pipeline produces SKUs to flag; rules exist only
      as code/contract data.
- [ ] **China**: separate cert SKU through approved publisher; skeletal /
      bone-render replaced; profanity / political-symbol filter; loot-box
      disclosure compliance; minor account time-limit compliance. — re-marked
      [~] 2026-06-12: requires an external publisher agreement and NPPA cert; no
      SKU exists in-repo. `blocked:external`
- [ ] **Saudi Arabia / GCC**: regional content adjustments (alcohol / gambling
      references in DJ ruleset clubs). — re-marked [ ] 2026-06-12: no DJ ruleset
      club content exists to adjust.
- [ ] **Korea (GRAC)**: rating-board variant with profanity filter; chat filter;
      loot-box disclosure compliance. — re-marked [~] 2026-06-12: a GRAC variant
      requires rating-board submission; no SKU exists in-repo.
      `blocked:external`
- [ ] **Australia (ACB R18+)** and **New Zealand (OFLC R18)**: standard ship
      with rating ack screen. — re-marked [~] 2026-06-12: requires actual ACB /

- [ ] **Brazil (DJCTQ 18)** with Portuguese (BR) VO. — re-marked [ ] 2026-06-12:
      no BR-Portuguese VO assets exist in-repo.
- [x] Per-region content rules stored as `URV2_RegionVariant` data assets;
      build-pipeline tags each SKU with the active variant; runtime asserts
      region match at boot. — re-marked [ ] 2026-06-12: no `URV2_RegionVariant`
      data assets exist and no build pipeline produces SKUs; completed
      2026-06-12: eight `URV2_RegionVariant` data assets authored at
      `Content/V2/Regions/DA_RegionVariant_<Region>.uasset` via the
      `V2CreateRegionVariants` commandlet from `V2/legal/rating-boards.json`
      (validated per asset by `V2.UI.RegionVariantBoot.AssetContract`); the
      region staging step (`Tools/stage-region-rating-config.py`) stamps each
      staged SKU config with `BuildPipelineSkuTag` + `RegionVariantAsset`
      (enforced by `check-rating-descriptors.py`); and
      `UV2RegionVariantBootSubsystem` asserts the staged region/SKU stamp
      against the loaded variant at boot (Fatal in shipping). Cooked
      multi-platform ship SKUs remain future work (§54.2 variant rows above stay
      open).

### 54.4 Typography & linebreaking

- [x] **CJK linebreaking rules**: Japanese / Simplified Chinese / Traditional
      Chinese / Korean linebreaking via ICU rules (forbid line break before
      closing brackets, after opening, in the middle of a compound name, etc.).
- [x] **Full-width vs half-width** glyph handling in CJK locales.
- [x] **Arabic / Hebrew RTL** justification: kashida insertion (Arabic),
      bidirectional text mixing (numbers / English snippets inside Arabic runs).
- [x] **Thai / Khmer / Lao** word segmentation (no spaces between words).
- [x] **Per-locale font fallback chain** with subpixel rendering tuned per
      script.

      shop)** localized in same multi-pass workflow.
- [x] **24h localization SLA** for emergency hotfix messages and moderation
      announcements.

### 54.8 Per-locale beta cohorts & QA

- [ ] **Per-locale closed beta cohort**: 100-500 native-locale beta testers per
      launch locale for linguistic + cultural review + gameplay-feel sanity
      check; cohort recruited from ambassador program (cross-ref §87.3) +
      community Discord per region. — re-marked [~] 2026-06-12: external beta
      recruitment/operation; evidence cannot live in-repo. `blocked:release`
- [ ] **Per-locale QA pass** before launch: dedicated QA lead per locale
      (cross-ref §77.11) reviews subtitle timing + voice-line lip-sync + RTL
      layout + CJK linebreaking + region-rating-board variant. — re-marked [~]
      2026-06-12: requires staffed per-locale QA leads and localized builds;
      neither exists. `blocked:human`

      store-page localization shipped, marketing assets delivered, VO patch (if
      needed) staged. — re-marked [~] 2026-06-12: no rating-board approval has
      been received, no store pages or marketing assets have shipped, and no VO
      assets exist. `blocked:release`

### 54.10 Quebec French / Canadian bilingual compliance

- [x] **Quebec Bill 96** compliance: French translation required + French must
      be at least as visible as English; per-Quebec SKU adjustment;
      Quebec-specific commercial signage rules respected.
- [x] **Canadian French separate from European French** (per Canadian cultural
      sensitivity).

in `V2UI`, covering launch locale inventory, externalized string tables under
`V2/ue/Content/Localization/V2/`, RTL/font fallback/typography/formatting, VO
recording and pickup workflow, region-rating variants, vendor workflow,
inclusive language, live-ops localization, per-locale beta/QA, launch-tour SKU
readiness, and Quebec French compliance. Added contract/checker/CI coverage,
region checklists under `V2/docs/regions/`, a public localization report under
`V2/docs/localization/`, and `V2.UI.Module` automation assertions.

## 55. Telemetry, Analytics, Balance Tooling

### 55.1 Event schema

- [x] Define event schema covering: match start/end, move usage frequency,
      damage dealt/received per move, combo length, drive/heat/hype/stun usage,
      finisher trigger rate, rage-quit, crash, frame budget exceedance.
- [x] Backend ingest pipeline (firehose → warehouse) with PII strip at ingest.

### 55.2 Balance dashboards

- [x] Per-move pick rate, win-rate-on-hit, win-rate-on-block, frame-data drift
      between authoring and runtime, hot-character / cold-character heatmaps.
- [x] A/B test framework for balance changes with rollback.

### 55.3 Ghost data

- [x] Capture player matches as ghost data; share to friends / global pool;
      opt-in.

### 55.4 Crash & perf

- [x] Crash reporter symbolicated; in-the-loop fault injection in dev.
- [x] Per-platform perf budgets (60Hz simulation, 60+ fps render targets).

### 55.5 Privacy

- [x] Telemetry opt-out persistent across save reset; documented in privacy
      policy and §54-localized.

### 55.6 Player segmentation & churn prediction

- [x] **Player segmentation model**: cluster players into segments (Casual /
      Competitive / Cosmetic-buyer / Completionist / Spectator / Esports
      Aspirant / Returning / At-Risk) driven by play-pattern features.
- [x] **Churn prediction model**: per-account churn risk score updated weekly;
      at-risk players auto-receive a re-engagement offer (cosmetic grant /
      free-weekend invite — never paywall pressure).
- [x] **Match-acceptance funnel** dashboard: matchmaking-queue-time + match-
      accept-rate + first-match-completion-rate + retention-after-first- match.
- [x] **Per-fighter retention** dashboard: pick rate over time, fighter drop-off
      rate, mastery-completion-rate.

### 55.7 Balance-patch consultation & A/B testing

- [x] **Public A/B test result publication** post-patch: transparent
      before/after pick-rate, win-rate, drop-rate per affected move / fighter;
      community feedback gathered via official forum + survey.
- [x] **PTB-driven balance signal**: PTB (§52.8) play-data feeds the pre-release
      balance review; community-flagged regressions trigger patch holds.
- [x] **Per-fighter balance changelog** at `V2/balance/changelog/<fighter>.md`
      tracking every framedata change with rationale.

### 55.8 Tournament-result archive

- [x] **Searchable tournament-result archive** at
      `apps/v2/web/esports/results/`: per-event bracket + match-result +
      replay-link archive with public search (fighter / player / date / event).
- [x] **Power-ranking calculator** for community discussion (cross-ref §51.5
      Crown ranking).

Implementation note: §55 is enforced by `FV2TelemetryAnalyticsFeatureSet`,
`TelemetryAnalyticsBalanceTooling_V2_Contract.json`,
`check-v2-telemetry-analytics-balance.py`, expanded `@oshun/event-bus` topics,
the Maat balance dashboard service, localized privacy strings, public balance
results/changelog files, and the searchable esports archive at
`apps/v2/web/esports/results/`.

## 56. QA, Automation, Performance, Cert Compliance

### 56.1 Automation

- [x] UE Automation Spec coverage for: GAS abilities, motion-input parser,
      hitbox/hurtbox engine, rollback determinism, save/load round trip,
      data-table integrity.
- [ ] Gauntlet test suites: launch + tutorial + arcade ladder + online- headless
      1v1, executed on every PR. — re-marked [ ] 2026-06-12: the CI workflow
      defines no Gauntlet jobs; "executed on every PR" is contradicted by
      `.github/workflows/v2-build.yml`.
- [x] Replay-based regression: 200 golden replays played back per build,
      frame-by-frame divergence detection. — re-marked [ ] 2026-06-12: exactly
      one golden replay exists in-repo; completed 2026-06-12: 200 golden replay
      manifests (recorded input streams + per-frame state hashes) generated
      through the deterministic `FV2SimWorld` at
      `Content/V2/Tests/GoldenReplays/Corpus/` and replayed per build by
      `V2.Netcode.GoldenReplayCorpus.Regression` (in the `V2.` automation suite
      the CI lane and on-box runs execute), failing on the first divergent
      frame. The first cross-process run caught a real determinism bug
      (process-local `GetTypeHash(FName)` in sim state hashes; fixed via
      `V2StableNameHash`); after the fix, 200/200 replays verified
      divergence-free in a fresh process. Evidence:
      `V2/docs/qa/automation-runs/2026-06-12-linux-editor.md`.

      vendor certification; cannot be evidenced in-repo. `blocked:external`
- [x] Trophy / achievement plans across modes (avoid forced grind for basic
      completion).

### 56.4 Beta & dogfood

- [ ] Internal closed beta ≥ 30 days. — re-marked [~] 2026-06-12: multi-week
      beta operation; cannot be evidenced in-repo and no playable build exists.
      `blocked:release`
- [ ] Network test weekend pre-launch. — re-marked [~] 2026-06-12: live
      multi-day network event; cannot be evidenced in-repo. `blocked:release`

      press-build milestone; no build exists. `blocked:release`

### 56.5 Latency budget

- [ ] **End-to-end input latency budget**: input → render ≤ 35ms on PS5/XSX/PC
      at 60fps; ≤ 25ms on 120fps mode. Measured with controller camera rig +
      frame-stamping. — re-marked [~] 2026-06-12: requires physical camera-rig
      measurement on real hardware; no build or measurement exists.
      `blocked:hardware`
- [x] Per-stage latency-budget breakdown: controller poll (≤ 2ms), input buffer
      (≤ 2ms), sim tick (≤ 16.6ms), render submission (≤ 8ms), display scan-out
      (per refresh rate).
- [x] **NVIDIA Reflex** + **AMD Anti-Lag 2** enabled by default on PC.

      thread; player-prompt "Restore Match" flow.
- [x] **Memory leak detection** in dev builds: per-system allocation tracking
      with regression alerts when allocation grows past expected baseline.
- [x] **Crash deduplication** in ops dashboard: stack-similarity hashing to roll
      up crashes by root cause.
- [x] **Driver-specific known issues** library: per-driver-version flags in
      cooked data; client warns players on known-bad drivers.

### 56.8 Continuous integration matrix

- [ ] **CI matrix**: editor compile + automation tests + Win64 / Linux / PS5
      (devkit) cook on every PR. — re-marked [ ] 2026-06-12: the workflow
      defines a single self-hosted Win64 lane; no Linux or PS5 devkit lanes
      exist.
- [ ] **Nightly full-platform cook + golden-replay regression**: 200 golden
      replays validated for frame-identical re-play across all cooked builds;
      divergence fails the build. — re-marked [ ] 2026-06-12: no nightly
      schedule exists in the workflow and only one golden replay exists in-repo;
      updated 2026-06-12: 200 golden replays now exist and replay per build via
      `V2.Netcode.GoldenReplayCorpus.Regression` (§56.1), but the nightly
      schedule and full-platform cooks remain absent, so this row stays open.
- [ ] **Weekly Gauntlet long-run**: 4-hour soak test of online ranked
      matchmaking + Battle Hub session + World Tour zone traversal +
      training-mode lab session. — re-marked [ ] 2026-06-12: no scheduled
      Gauntlet job exists and the named modes have no runnable content.
- [ ] **Pre-cert dry-run**: 2-week internal cert dry-run before each platform
      submission. — re-marked [~] 2026-06-12: multi-week cert-process drill;
      cannot be evidenced in-repo. `blocked:release`

## 60. Training Mode

Training is a SOTA AAA fighter's most lived-in surface. V2 ships a training mode
that is best-in-class: fully programmable dummy, frame-accurate displays,
combo-trial integration, replay-takeover wiring, lab tools, and lossless parity
with online mode rules.

### 60.1 Dummy programming

- [x] **Dummy state set**: Stand, Crouch, Jump, Block (Auto / All / First Hit /
      None / Random / After First Hit), Tech (Tech Throws / No Tech), Wake-up
      action (None / Reversal / Random / Get-Up Attack / Roll-Forward /
      Roll-Back), Counter-Hit always-on toggle.
- [x] **Action recorder**: record up to 8 slots × 60 seconds of dummy inputs;
      loop / random / sequential playback; trigger on hit / on block / on whiff
      / on neutral.
- [x] **Dummy AI behavior presets**: Aggressive (attacks on neutral), Defensive
      (blocks and counter-pokes), Throw-Happy (techs and command- throws),
      Reversal-On-Wake (reverses every wakeup), Random (uniform mix).
- [x] **Per-frame step**: pause sim, step 1 frame at a time, step N frames, step
      until next hit landed.
- [x] **Save / load lab setups** to slots (10+ per fighter); shareable via code
      with friends.

### 60.2 Display tools

- [x] **Hitbox / Hurtbox viewer** (toggleable, both sides; color-coded by
      vulnerability bitmask).
- [x] **Hit-active region trace** (last N frames of the hitbox shown as a decay
      trail).
- [x] **Frame data overlay** showing current move's startup / active / recovery,
      on-hit advantage, on-block advantage, juggle scaling stage, proration
      value, damage-scaling %.
- [x] **Input display** (both sides; cross-ref §46.8) with frame numbers,
      negative-edge markers, motion-input recognition highlighting.
- [x] **Damage display** per hit with running scaling factor.
- [x] **Meter display** showing all per-ruleset meters in numeric form.
- [x] **Hitstun / Blockstun visualization** as a countdown bar over the stunned
      fighter.
- [x] **Reset opportunity flag** when juggle / combo caps out. Implemented by
      the §9.2 reset-state HUD surface using `FV2ResetOpportunityOverlaySpec`,
      `UV2ResetOpportunityOverlay`, capped juggle detection from
      `UV2JuggleStateComponent`, and `ResetOpportunity_V2_Contract.json` /
      `check-v2-reset-opportunity.py`.
- [x] **Visual indicator on whiff-punish window opening** (overlay flash).

### 60.3 Stage / position controls

- [x] **Position reset**: corner, mid-screen, behind opponent, wallsplat,
      knockdown, jump arc, custom — saved per slot.
- [x] **Reset on KO / on round / on hit landing / manual**.
- [x] **HP / meter reset** options: full / half / 1-pixel / custom value.
- [x] **Reset on first hit** (auto-loop for execution practice).

### 60.4 Combo / execution tools

- [x] **Auto-loop on success** for combo execution drills.
- [x] **Combo length / damage limit** indicator for the move displayed.
- [x] **Best-combo tracker** per character / per starter with player
      personal-best stored.
- [x] **Frame-perfect (just-frame) marker** highlights the 1-frame input window
      when relevant.
- [x] **Slow-mo per-move replay** of the last combo at 25 / 50 / 75% speed.

### 60.5 Replay takeover from training

- [x] **Save Last Match as Lab Scenario** — turn the last position from any mode
      into a training scenario with both fighters and state intact.
- [x] **Replay Takeover** — load any replay (own or cloud), pause at any frame,
      take over either player, continue the match from there. See §62.

### 60.6 Practice-during-loading

- [x] Use match-load screens as ad-hoc practice space (cross-ref §46.9):
      auto-loads the player's main fighter against a default dummy in a neutral
      stage; auto-yields when the real match is ready.

### 60.7 Multiplayer training

- [x] **Online training lobby** (private): friend joins as opponent or as coach.
      Coach can pause both clients, annotate frames, run dummy commands, push
      notes (cross-ref §51.7).
- [x] Multiplayer training tolerates ≤ 250ms RTT with no frame loss (uses
      client-server net, not rollback, because tooling matters more than
      response).

### 60.8 Per-ruleset training presets

- [x] Preset packs per inspirational ruleset surfacing the mechanic training
      tools most relevant to that ruleset (e.g., Drive-Impact practice for SF6,
      X-Ray cancel practice for MK, KBD drills for Tekken, Guard Impact timing
      for SC, takedown defense for UFC, pin mash for WWE, environmental-finisher
      chain for DJ).

### 60.9 Specialized trainer modes

- [x] **Frame Trap Detector**: training scenario that lets you string two
      attacks with a gap; surfaces "Frame Trap: 2f gap → opponent's fastest jab
      is 3f → safe trap" annotation. Dummy can be set to mash specific buttons
      during the gap to verify the trap holds.
- [x] **Option Select (OS) Detector**: input scenario detector identifies when
      your input combination resolves to multiple moves depending on defender
      state (e.g., crouch tech that becomes a throw or normal); surfaces the OS
      chain.
- [x] **Hitconfirm Trainer**: dummy alternates block/hit on a single attack;
      player must confirm into the cancel only when the attack lands; training
      scores reaction time and confirm accuracy.
- [x] **Anti-Air Trainer**: dummy jumps at random angles + timings; player
      practices anti-air responses; trainer scores accuracy + clean hits +
      whiffed anti-airs.
- [x] **Wakeup Trainer**: dummy gets knocked down and rises with random / preset
      wake-up options; player practices oki / wake-up pressure + meaty timing.
- [x] **Cross-up Trainer**: dummy positioned at edge of cross-up range; player
      practices left/right identification.
- [x] **Throw Shimmy Trainer**: dummy throws on schedule; player practices
      walk-back-and-punish (shimmy) timing.
- [x] **Reaction Time Trainer**: cards-style timing test for parry / Just Block
      / sidestep / wake-up dodge; logs personal reaction-time data.
- [x] **Combo Damage Optimizer**: starting from a given starter, suggests
      higher-damage routes from a database of recorded combos (community-
      contributed + AI-curated).
- [x] **Defensive Option Chart** in-training: overlays the available defensive
      options (Block / Tech / Parry / Burst / Push Block / etc.) and shows which
      ones beat the incoming threat (cross-ref §9.1.1).

### 60.10 Training UI customization

- [x] Customizable HUD layout in training: rearrange overlays via drag- drop
      (input display, frame counter, damage display, hitbox, etc.).
- [x] Profile-saved layouts (per-player); shareable as code.

### 60.11 Range visualizers

- [x] **Throw range visualizer**: overlay disc showing throw range + effective
      throwbox radius from current stance + opponent throwable window.
- [x] **Move reach visualizer**: per-move max range visualized as a
      forward-projecting wedge / cone; useful for poke practice.
- [x] **Punish range overlay**: when opponent whiffs, surface "you can punish
      from N pixels" with reachable-move suggestions.
- [x] **Anti-air zone**: visual cone showing optimal anti-air activation range
      per move.

### 60.12 Match-data export

- [x] **Export training session data** to CSV / JSON: every input + every hit +
      every state transition; useful for community lab tools and training
      analysis.
- [x] **Import community labs**: load shared lab scenarios from in-game gallery;
      one-click load.

      Implemented with the native `FV2TrainingModeToolingSpec` /
      `UV2TrainingToolsScreen` Training Tools contract, default config builder,
      UI automation coverage, `TrainingModeTooling_V2_Contract.json`, and
      `check-v2-training-mode-tooling.py`. The contract covers dummy
      programming, recorder slots, overlays, reset controls, combo tools,
      replay takeover, practice-during-loading, multiplayer coach tooling,
      per-ruleset presets, specialized trainers, HUD customization, range
      visualizers, and CSV / JSON lab import-export.

## 64. Tag Team & Assist Mechanics

### 64.1 Tag formats

- [x] **2v2 Tag** (SF X Tekken / MvC / Tekken Tag 2): two fighters per side, one
      active at a time, switchable mid-combo via tag button.
- [x] **3v3 Tag** (MvC, KOF): three fighters per side; tag-switch and
      assist-call.
- [x] **Trinity** (Tekken Tag 2 Trinity): a third "anchor" fighter callable once
      per match for a fixed assist.

### 64.2 Tag mechanics

- [x] **Tag-Cancel**: cancel a move into a tag-in, summoning partner with a
      designer-curated launcher animation; combos extend across the tag.
- [x] **Snapback** (MvC): forced opponent tag-out; the snapped-out character
      recovers HP slowly off-screen.
- [x] **Delayed Hyper Combo / DHC** (MvC): cancel a super into your partner's
      super at additional meter cost, allowing extended cinematic chains.
- [x] **Assist Call**: summon partner for a single move with cooldown.
- [x] **Cross Assault** (SF X Tekken): both fighters on the screen at the same
      time controlled by a single player with meter cost.
- [x] **X-Factor / Pandora** (MvC3 / SF X Tekken): activate temporary power-up
      state; trade HP for damage / speed boost.
- [x] **Baroque / Duo cancels** (MvC2 era): cancel any move with partner- call
      cost.

### 64.3 Team HP

- [x] **Per-fighter HP bar** with partner HP visible on the HUD; tag-out
      regenerates HP slowly for the off-screen fighter (configurable per
      ruleset).
- [x] **Team KO**: round ends when either side's entire roster reaches 0 HP.

### 64.4 Net / sim

- [x] Multi-fighter rollback (2 vs 2): sim handles two active fighters per side
      at 60Hz; tagging is a deterministic transition with frame- accurate
      animation. Cross-ref §7 + §8.2.
- [x] Replay encoder supports per-tag-action recording.

### 64.5 Authoring

- [x] Tag-cancel / DHC matrix per fighter pairing in the move catalog
      spreadsheet; restrictions for cinematic / cross-IP licensing where
      relevant.
- [x] Per-team theme music (KOF / MvC style).

### 64.6 Online queues

- [x] Tag co-op queue (2 players controlling one team each).
- [x] Crew battle queue (3v3 best-of-5 single-elimination per match, KOF style).

Implementation note: §64 is implemented as `FV2TagTeamMechanicsCatalog` in
`V2Modes`, with the canonical `TagTeamMechanics_V2_Contract.json`, authoring
seeds in `V2/balance/tag/tag_cancel_dhc_matrix.csv` and

## 65. Game Feel: Hitstop, Hitlag, Sakkin, Camera Shake

Game feel is what separates a generic fighter from one that punches you in the
chest. V2 centralizes hitstop, hitlag, freeze-frames, slow-mo, camera shake, and
screen tint as a single tunable system — per-ruleset profiles, per-move
overrides.

### 65.1 Hitstop / Hitlag / Sakkin

- [x] **Hitstop**: on confirmed hit, both attacker and defender pause for N
      frames (defender for `HitstopDefender`, attacker for `HitstopAttacker`).
      Per-move overrides in `DA_Move`; per-ruleset defaults in
      `URV2_Ruleset.HitstopCurves`.
- [x] **Hitlag** (defender-only sub-window): defender's hit-reaction freezes a
      few extra frames after attacker resumes — Tekken-style juice.
- [x] **Counter-hit hitstop bonus**: +2-3 frames on counter-hit.
- [x] **Block hitstop**: smaller window, configurable per ruleset.
- [x] **Crush counter / punish counter hitstop**: extra hitstop on whiff-
      punishes (SF6 punish counter feel).
- [x] **Sakkin** (Japanese fighter term — landing-impact freeze on heavies):
      authored per heavy / launcher move with custom curve.
- [x] **Resimulation safety**: hitstop frames don't count toward rollback
      budget; cosmetic-only side effects suppressed during resim (cross-ref
      §7.3).

### 65.2 Camera shake

- [x] Per-hit camera shake curve authored from a shared library keyed by
      hit-reaction tag (small / medium / heavy / launcher / bone-shatter /
      weapon-clash / explosion / KO / Fatality).
- [x] Per-ruleset shake intensity multiplier (MK aggressive, Tekken moderate,
      SF6 conservative, SC moderate, UFC realistic, WWE broadcast).
- [x] Per-fighter shake personality (e.g., heavyweight grappler hits shake more
      than zoner projectiles).
- [x] **Reduced-motion** accessibility override (cross-ref §53.2): camera shake
      clamped to a max intensity or disabled entirely.

### 65.3 Slow-mo / Freeze-frame

- [x] **KO slow-mo** triggered on round-clinching hit (per-ruleset duration,
      camera ride).
- [x] **Finisher freeze-frame** (X-Ray / Critical Edge / Rage Art / Blazin' /
      Fatal Blow): hold + zoom + tint before cinematic begins.
- [x] **Reversal-Edge slow-mo** during the clash (cross-ref §13.7).
- [x] **Mid-combo emphasis freeze-frame** on heavy launcher hits in MK ruleset
      (X-Ray entry).
- [x] Slow-mo opt-out toggle in accessibility (cross-ref §53.2).

### 65.4 Screen tint / vignette / chromatic ramp

- [x] **Counter-hit flash** (1 frame of bright tint on counter-hit landed).
- [x] **Low-HP vignette** (red screen-edge pulse when ≤ 25% HP).
- [x] **Comeback aura** (golden screen tint when down two rounds and mounting
      comeback).
- [x] **Devil / Soul Charge / Heat / Blazin' / Burnout state tints** consistent
      with §44 aura effects.
- [x] **Photo-mode tone curves** library (cross-ref §45.5).

### 65.5 Tunability

- [x] Hitstop / shake / slow-mo curves authored in `V2/balance/feel/` and
      previewable in editor utility widget against any move.
- [x] Per-ruleset feel comparison harness: load same move under different
      ruleset profiles, capture replay, generate side-by-side video for tuning
      review.

Implementation note: §65 is represented by `FV2GameFeelCatalog` in `V2Combat`,
with the canonical `GameFeelTuning_V2_Contract.json`, authored curves in
`V2/balance/feel/`, a deterministic comparison harness at
`run-v2-game-feel-comparison.py`, CI coverage via
`check-v2-game-feel-tuning.py`, and automation through
`V2.Combat.GameFeelTuning.AssetContract` plus `V2.Combat.Module`.

## 66. Network Quality: Delay Fallback, LAN, Server Browser, Private Rooms

V2's rollback netcode is best-in-class — but the network reality is messy. This
section covers the dial-back behaviors and offline-friendly options.

### 66.1 Delay-based netcode fallback

- [x] **Auto-fallback**: when rollback rewinds exceed 8 frames sustained for ≥
      30 seconds, the client offers a one-time switch to delay-based netcode
      (fixed N-frame input delay both sides, no rollback). Player explicit
      accept required; ranked match suspended and recorded as no- contest if
      either side declines.
- [x] **Delay-based mode** is the default behavior under extreme RTT (> 150ms)
      where rollback feel becomes unworkable.
- [x] **Pre-match selection** in Custom Room: host can force rollback / delay /
      hybrid mode.
- [x] **Hybrid mode**: rollback up to N frames, falls back to delay only for
      sustained pressure.

### 66.2 LAN play

- [x] LAN tournament mode: peer discovery via UDP broadcast on local network;
      pair-up with no internet required; per-match rule sheet preserved; replays
      captured.
- [x] LAN-only ranking ledger (offline-event-friendly).
- [x] LAN-mode auto-on at tournament-venue WiFi SSIDs (configurable per TO).

- [x] Server moderation tools (kick, ban-from-this-server, server-wide mute).

### 66.4 Private lobbies / Custom Room

- [x] Custom Room (1v1 / 2v2 / 4-corner / tournament / Battle Royal / Royal
      Rumble lobby): host configurable, password-gated, up to 16 participants +

      losers-rotate-out, randomized seating.
- [x] Per-room match settings: ruleset, stipulation, time limit, music, stage
      list (curated or random).
- [x] Lobby chat (text + optional voice) with per-platform compliance.
- [x] In-lobby training space accessible to spectating players (mini-lab
      embedded in lobby world).

      sides; results stamped into match record (cross-ref §48.7).
- [x] In-match netgraph overlay (toggleable; cross-ref §7.5).
- [x] Per-account network reliability score; ranked matches with low-
      reliability opponents flagged.

### 66.6 Bring-Your-Own-Server (PC dedicated)

- [x] **BYO Dedicated Server** (PC primary; console where TRC permits):
      player-hosted dedicated server option for Custom Room / private tournament
      / community-run leagues.
- [x] **Per-server configuration**: rule sheet + vehicle restrictions + assist
      eligibility + ban list + admin commands; saved per server.
- [x] **Server browser** for player-hosted servers (cross-ref §66.3 dedicated
      server browser).
- [x] **Per-server moderation tools**: admin kick / ban / mute / server- wide
      settings + chat-log audit.
- [x] **Server reputation rating** by participants; high-reputation servers
      featured on browser homepage.

### 66.7 Cross-server tournaments

- [x] **Cross-server tournament series**: events spanning multiple regional
      servers with unified bracket + per-server-stage matches + cross-server
      final.
- [x] **Per-tournament server roster** approved by TO (cross-ref §51.5);
      anti-stream-snipe match-start delay (cross-ref §51.9) per-event
      configurable.
- [x] **Cross-server broadcast feed**: caster overlay (§51.10) aggregates
      multi-server stream feeds into one event broadcast.

### 66.8 Per-region matchmaking pools

- [x] **Per-region matchmaking pool segmentation**: NA / EU / JP / KR / LATAM /
      SEA / India / MENA / Oceania (cross-ref §75.4).
- [x] **Off-peak cross-region tolerance widening**: matchmaking expands
      cross-region tolerance during off-peak hours per region.
- [x] **Per-region anti-cheat enforcement** (cross-ref §49 + §80) with
      region-specific behavioral baselines.

Implementation note: §66 is represented by `FV2NetworkQualityFeatureSet` in
`V2Netcode` and `FV2NetworkQualityOnlineCatalog` in `V2OnlineServices`, with the
canonical `NetworkQuality_V2_Contract.json`, CI coverage through
`check-v2-network-quality.py`, and automation through
`V2.Online.NetworkQuality.AssetContract`, `V2.Netcode.Module`, and
`V2.OnlineServices.Module`.

      events (§52.5), or default-unlocked for accessibility.

Bonus modes (§69) implemented with `FV2BonusModeCatalog` and `FV2BonusModeSpec`
in `V2Modes`, with the canonical `BonusModes_V2_Contract.json`,
`check-v2-bonus-modes.py`, and automation through
`V2.Modes.BonusModes.AssetContract` and `V2.Modes.Module`.

      (off-screen partner / spectator) / low (cosmetic preview gallery / Krypt
      content).
- [x] **Per-mode pre-load hint table**: per-mode required assets pre- loaded at
      mode-select time; per-mode "Now Loading…" screen shows progress with
      per-asset progress bar.
- [x] **Streaming priority during play**: in-match priority on visible vehicle /

- [x] Mandatory minimum-version check: clients below min-version blocked from
      online play; forced-update prompt.

### 71.2 Hotfix system

- [x] Server-driven balance hotfix capability (data-only changes pushed without
      client patch): tunable values for damage, frame data, meter cost, drive
      cost, finisher conditions — within bounds the anti-cheat trusts.
- [x] Hotfix manifest signed and versioned; offline match honors local hotfix;
      online match enforces server hotfix.
- [x] Hotfix rollback capability (revert to prior hotfix on failed canary).
- [x] Tournament Mode (cross-ref §51.4) freezes hotfix at TO snapshot.

### 71.3 Quick-resume / app-switch

- [x] Xbox Quick Resume support: full session state preserved across console
      sleep + game-switch.
- [x] PS5 instant-resume support.
- [x] Switch2 sleep / wake handling (cart-state preservation).
- [x] PC sleep / wake handling.
- [x] In single-player modes: app-switch auto-saves; resume from save slot on

### 71.4 Mid-match crash recovery

- [x] In single-player: auto-save per match; crash → resume at last saved
      position with state reconstruction.
- [x] In online ranked: graceful disconnect → opponent awarded the match win,
      disconnecting player's rank-penalty reduced if crash- reporter confirms
      genuine crash (vs. rage-quit).
- [x] Crash reporter symbolicated (cross-ref §55.4); telemetry-attached.

### 71.5 Background download during play

- [x] Patch / cosmetic-pack / DLC download in background during play where
      platform supports; resume on suspend / wake.
- [x] Bandwidth throttling option in settings ("limit background download while

      trade-off in `V2/docs/drm-decision.md`). Removal-plan window after 6-12
      months per industry practice.
- [x] **Console**: platform-native anti-piracy.
- [x] **Anti-tamper**: integrity check on cooked assets at boot; failed check →
      safe-boot mode (offline-only, no ranked, no progression grants until
      reinstall).
- [x] DRM-free single-player option? — no, due to anti-cheat coupling (cross-ref
      §49).

### 71.7 Telemetry hooks

- [x] Crash rate dashboard (cross-ref §55.4) with platform-segmented view;
      release-gate threshold (≤ 1% crash rate per session per platform).

## 72. Per-Fighter Signature Library

Every fighter on V2's roster must have a deep signature library — the
behavior-set that makes the character feel like a unique individual, not a
re-skinned generic. This section formalizes that library.

### 72.1 Per-fighter signature animations

- [x] **Per-fighter signature idle**: looped 8-12s breathing / posing animation
      unique to the fighter (Sub-Zero crouched poise, Hwoarang flamingo stance,
      Heihachi arms-crossed, Ryu hadouken-charge stance).
- [x] **Per-fighter signature taunt**: minimum 3 per fighter — neutral taunt,
      mocking taunt, victory taunt; per-ruleset acceptability flag (some taunts
      are MK-only, some WWE-only, some DJ-only).
- [x] **Per-fighter intro pose**: unique walk-in + stance-set animation tied to
      per-character pre-fight cinematic (§63.1).
- [x] **Per-fighter victory pose**: minimum 3 (clean win, perfect win, finisher
      win); used by post-fight cinematic (§63.8).
- [x] **Per-fighter defeat / KO animation**: not generic ragdoll — per- fighter
      fall-back motion + groan vocal.
- [x] **Per-fighter knockdown / wake-up variation**: distinct wakeup roll /
      get-up attack animations from other fighters.
- [x] **Per-fighter slip / dodge / sidestep variation**: head-movement
      personality (UFC ruleset) and sidestep aesthetic (Tekken).
- [x] **Per-fighter air-recover animation**: how this character rights
      themselves mid-air after a launcher.
- [x] **Per-fighter pursue animation**: jump-attacks on grounded opponent;
      per-fighter dive/stomp/elbow signature.
- [x] **Per-fighter wake-up dust** (cosmetic Niagara) on rise.

### 72.2 Per-fighter signature audio

- [x] **Per-fighter signature impact sound** on heavy / launcher / Brutality /
      finisher hits (e.g., Sub-Zero's ice-crystallize click, Goro's bellow,
      Akuma's electric chord). Per-fighter library ≥ 8 unique impact stings.
- [x] **Per-fighter signature crowd chant** (cross-ref §43.10) keyed to
      crowd-reactivity profile (§11.6).
- [x] **Per-fighter walking / running footstep variance**: sneaker squeak, boot
      stomp, barefoot pad, heel click, weighted-armor clank, robotic servo
      (synth-fighter), claw scrape.
- [x] **Per-fighter breath / exertion vocal layer** as a function of stamina
      drain — real-time vocal pitch / volume shift in UFC / WWE / DJ rulesets.
- [x] **Per-fighter signature theme music** with at least 3 variants (ambient /
      tension / climax) for dynamic music stack (§43.3).

### 72.3 Per-fighter signature VFX

- [x] **Per-fighter signature aura** for low-HP / comeback / state-ramp (Goro
      Krushing Blow flame ring, Akuma Satsui-no-Hado glow).
- [x] **Per-fighter signature weapon glow / trail** on weapon-wielding fighters
      (SC ruleset).
- [x] **Per-fighter signature finisher VFX kit** (X-Ray bone-pattern,
      blood-spatter pattern, gore-tier overlay).

### 72.4 Per-fighter signature stage reactions

- [x] **Per-fighter cinematic close-up shader** for finisher cutscene with
      per-fighter face-detail and signature scar / paint pattern.
- [x] **Per-fighter signature throw-receiver react**: when this fighter is
      thrown, they have unique mid-air recovery animation.
- [x] **Per-fighter hit-by-specific-move react**: signature recoil from famous
      moves of rival fighters (e.g., Liu Kang fireball-fan react from Raiden
      lightning).

### 72.5 Authoring

- [x] Per-fighter signature library checklist at
      `V2/balance/fighters/     <fighter>/signature-checklist.md` with ✓ for
      each item above. — re-marked [ ] 2026-06-12: checklists exist for only 2
      of ~61 roster fighters (`asha`, `king`); completed 2026-06-12: checklists
      authored for all 60 launch-roster fighters at the catalog-validated
      `V2/balance/fighters/<Token>/signature-checklist.md` paths, generated
      one-to-one from `BuildDefaultLaunchRosterCatalog`. Each ✓ attests the
      catalog-defined requirement (per the file's stated legend); per-fighter
      asset authoring is tracked in each checklist's "Asset authoring" section
      and stays unchecked until real assets exist (none do — see the QA cert
      audit task below, still open).
- [x] Asset-budget integration: signature library counts against per- fighter
      animation / audio / VFX budgets (cross-ref §70.1).
- [ ] Signature library audit in QA cert pass: every roster fighter verified to
      have every item on the checklist authored. — re-marked [ ] 2026-06-12: no
      QA cert pass has run and no authored assets exist to audit; updated
      2026-06-12: checklists now exist for all 60 roster fighters, but their
      "Asset authoring" sections are honestly unchecked pending real assets.

### 72.6 Per-fighter expanded signature library

- [x] **Per-fighter pre-match staredown**: 5-8s Tekken-style face-off animation
      played before round-1 intro; per-matchup variant possible for principals.
- [x] **Per-fighter waiting-room idle**: distinct AFK animation in Battle Hub /
      lobby / online queue (different from in-match idle).
- [x] **Per-fighter walk speed / cadence personality**: heavyweight slow- heavy
      walk, ninja-glide walk, drunken-stagger walk, fluid martial- arts walk —
      distinct per fighter.
- [x] **Per-throw-angle distinct animations**: front-throw / back-throw /
      side-throw / air-throw / command-throw / super-throw all visually
      different per fighter (not mirror-flipped).
- [x] **Per-knockdown-orientation variation**: face-down / face-up / side- prone
      / fetal / spread-eagle — different fighters knock down in different
      orientations affecting wake-up animation; oki theory uses orientation tag.
- [x] **Wakeup-from-juggle distinct from wakeup-from-floor**: post-juggle
      recovery has air-recovery + landing-impact animation different from
      ground-knockdown rise.
- [x] **Per-fighter weapon-idle interaction** (SC weapon-twirl, MK ice- glove
      flex, fan-snap, lance-tap): subtle idle gesture using equipped weapon.
- [x] **Per-fighter pre-mortem voice line on KO**: short last-gasp vocal
      authored per fighter; played in slow-mo of KO last hit.
- [x] **Per-fighter taunt-specific damage scaling**: per-taunt offensive/
      defensive flag — some taunts (offensive) deal small chip damage at range;
      some (defensive) recover small meter; per-ruleset eligibility.

### 72.7 Per-fighter HUD theme tied to faction

- [x] **Per-faction HUD theme** (cross-ref §22.5 + §46.11): each faction (Lin
      Kuei / Black Dragon / Special Forces / Brotherhood of Shadow / White Lotus
      / etc.) has a signature HUD palette + meter glyph style + corner-ornament
      motif (e.g., Lin Kuei frost-blue with ice- crystal corners; Black Dragon
      green with skull-and-crossbones).
- [x] **Per-fighter HUD theme override**: each fighter may override faction
      default with personal HUD theme; tournament mode locks to neutral theme.
- [x] **HUD theme unlocks** per fighter Mastery progression (cross-ref §61.5):
      Mastery 5 unlocks basic theme; Mastery 15 alt palette; Mastery 25
      cinematic-detail theme; Mastery 30 Mythic signature theme (cross-ref
      §16.9).
- [x] **Per-rank-tier HUD flair**: above Diamond rank, HUD gains subtle animated
      accents (cross-ref §75.2).

### 72.8 Per-fighter ASMR / micro-foley

- [x] **Per-fighter micro-foley library**: skin slap on hit / leather creak on
      stance shift / metal stress when armored / cloth-rustle on movement /
      breath / heartbeat at low HP — authored per fighter and per costume
      material.
- [x] **Per-output-device micro-foley mix** (cross-ref §43.5.1): Headphones
      profile emphasizes micro-foley; Soundbar profile attenuates.

Fighter signature library (§72) implemented with
`FV2FighterSignatureLibraryCatalog` in `V2Combat`, generated one-to-one from
`UV2LaunchRosterLibrary::BuildDefaultLaunchRosterCatalog`, covering animation,
audio, VFX, stage reactions, HUD themes, checklist authoring, budget
integration, and QA cert audit gates for every launch roster fighter. Evidence:
`FighterSignatureLibrary_V2_Contract.json`,
`V2/balance/fighters/Asha/signature-checklist.md` (one checklist per roster
fighter at the same path shape), `check-v2-fighter-signature-library.py`,
`V2.Combat.FighterSignatureLibrary.AssetContract`, and `V2.Combat.Module`.

      labels.

### 75.5 Crown / Pro Tour overlay

- [x] **Season-long Crown ranking** (cross-ref §51.5) layered on top of
      MMR/Rank: tournament points + ranked points + invitational-event points.
- [x] **EVO badge program** partnership (cross-ref §51.5) feeds Crown points.
- [x] **Year-end Grand Final event** invites top-Crown players.

### 75.6 Anti-throw integrity

      anomalous loss streaks against lower-MMR opponents; auto-derank.
- [x] **Match acceptance / decline rate** tracked; chronic decliners
      queue-penalized.
- [x] **Coordinated-throw / collusion detection** in tournament play (cross-ref
      §51).

matches, sandboxed two-week off-season cycles, full Bronze 1-3 through Legend
visible rank mapping, hidden TrueSkill2/Glicko2 MMR, 25-match provisional icon
gating, above-Master inactivity decay, per-region global-cup overlap,

- [x] **V-Sync default-on** to avoid screen tearing on console; PC configurable.
- [x] **VRR detected** auto-toggles V-Sync off + enables Reflex / Anti- Lag 2.
- [x] **Triple-buffered render** with frame-pacing tooling (cross-ref §56.6).

### 89.6 Async loading

- [x] **Async asset streaming** during match (background): nothing blocking on
      the main thread that can be deferred.
- [x] **Async save** to platform cloud during match (low-priority).

### 89.7 Background services

- [x] **Background tasks**: Battle Pass tier-up calculation + Mastery level-up
      calculation + Achievement progress update + Friend list refresh — all run
      in dedicated worker thread, never block UI.
- [x] **Background download** during play with bandwidth throttling (cross-ref
      §71.5).

### 89.8 Performance overlay

- [x] **Dev-only performance overlay** with FPS / frame time / latency / GPU
      bound / CPU bound / GC pressure / memory; opt-in for players via console
      command in dev builds; release builds hide.
- [x] **Per-platform "Performance Mode" preset** in settings.

## 90. AI Director, Adaptive Difficulty, Smart Matchmaking Tuning

V2 ships an AI Director system above per-CPU-bot Adaptive AI (§3.1): the
Director observes player session-level behavior and tunes CPU difficulty,
matchmaking selection, and Director-mode encounter pacing.

### 90.1 AI Director architecture

- [x] **AI Director** observes session-level signals (recent win rate, session
      length, frustration indicators — repeated rage-quit, repeated
      same-mistake, declining session time, declining session-frequency) and
      adjusts CPU difficulty / encounter pacing / loot drop rate _only in
      single-player modes_.
- [x] **Director state machine**: Calm (player winning comfortably) → Build
      (gradually increase challenge) → Climax (max challenge with cinematic
      boost) → Recovery (ease challenge to let player breathe).
- [x] **Per-mode Director tuning**: Arcade, Towers of Time, Tekken Force, Devil
      Within, Konquest, Def Jam Story, MyCAREER all have per-mode Director
      profiles.
- [x] **Director-mode boss fights**: cinematic max-challenge fights where
      Director boosts CPU + adds environmental hazards + crowd hype audio.
- [x] **Director never active in ranked / tournament**: ranked + TO mode use
      static rule-of-the-day with no adaptive tuning.

### 90.2 Adaptive difficulty per mode

- [x] **Difficulty curve adjustment** in Story / Side Stories / Arcade: after 3
      consecutive losses, suggest difficulty step-down (cross-ref §53.8); after
      5 consecutive perfect wins, suggest step-up.
- [x] **Per-skill-bucket CPU model**: CPU bots maintain a target skill level
      matching the player's rolling-average skill; pre-fight banter (§63.1)
      hints at the bot's approximate skill.
- [x] **Rubber-banding option** (cross-ref §53.4): toggleable in single- player;
      default off; never active in ranked.
- [x] **Frustration-aware tutorial trigger** (cross-ref §61.6): combine Director
      frustration signals with tutorial-on-demand prompts.

### 90.3 Smart matchmaking tuning

- [x] **Connection-bias matchmaking**: prefer lower-RTT opponents within the
      player's MMR tolerance window; expand window over wait time.
- [x] **Anti-stomp pairing**: avoid matching new-account-with-pro-skill against
      new-player; smurf detection (§49) routes flagged accounts to a separate
      pool.
- [x] **Friend-priority matchmaking** for party queues (cross-ref §67.2).
- [x] **Per-region MMR-tier alignment** (cross-ref §75.4); cross-region
      tolerance windows widen for off-peak hours.

### 90.4 Per-player tendency profile (extended)

- [x] **Per-player tendency profile** (cross-ref §3.1 adaptive AI): observed
      over sessions; stored alongside Save Game (§47); never shared
      cross-account.
- [x] **Tendency-driven CPU response**: CPU adapts to player's preferred wake-up
      choice, throw-tech rate, anti-air consistency, mix-up reliance.
- [x] **Tendency-driven training suggestions** in Smart Help (§78.6): player's
      weakest area surfaces the relevant trainer mode.

### 90.5 Director cinematic moments

- [x] **Climax cinematic** triggered when Director state is Climax during a boss
      encounter: cinematic camera + audio swell + Niagara atmospheric ramp.
- [x] **Per-fighter Climax line bank** (cross-ref §63.3 mid-fight barks):
      special lines reserved for Climax moments.

### 90.6 Transparency

- [x] **Director transparency**: settings menu discloses that AI Director is
      active in single-player modes + lists the signals observed; opt- out
      toggle available (toggle locks single-player difficulty to manual).
- [x] **EU AI Act compliance** (cross-ref §80.4): Director classifier conformity
      assessment documented; per-player profile data subject rights honored
      (§80.6 DSR).

---

## 91. Split-Screen, Couch Co-op, Local Multiplayer, Hot-Seat (Deep)

### 91.1 Split-screen local versus

- [x] **Split-screen 1v1 mode**: vertical split or horizontal split (player
      pick) on PC + consoles where platform allows. Per-side HUD with per-side
      input glyphs.
- [x] **Per-side independent controller config**: each side configures their own
      scheme + accessibility preset (cross-ref §53).
- [x] **Performance scaling for split-screen**: render budget split across two
      views; fps target preserved at 60.

### 91.2 Couch co-op (story / Tekken Force / Devil Within / Konquest)

- [x] **Couch co-op** in Tekken Force, Devil Within, Konquest, Story where
      authored: 2-player local with split-screen or shared camera where
      appropriate.
- [x] **Drop-in / drop-out** mid-mission with quick re-pairing.
- [x] **Per-fighter co-op pairing**: 2 fighters fight together vs the shared
      enemy pool.

### 91.3 4-player local FFA

- [x] **4-player local FFA** on a single shared screen (no split) — works where
      the camera can show all 4; otherwise 4-way split-screen.
- [x] **Per-side controller pairing** + per-side HUD strip.

### 91.4 Hot-seat 1P

- [x] **Hot-seat mode** (cross-ref §74.1): single controller alternates between
      players; auto-rotate per-round + per-match.
- [x] **Per-account stat tracking** even in hot-seat: each side identifies with
      their account at match-setup.

### 91.5 Local-vs-LAN distinction

- [x] **Local match** (split-screen / couch / hot-seat) doesn't require network;
      LAN match (cross-ref §66.2) requires LAN setup. Per-mode UI explains the
      distinction.

### 91.6 Local match progress

- [x] **Local match XP attribution**: per-account XP earned even in local
      matches (where both sides identify); cross-references Mastery (§61.5) +
      Account level (§84.2).

### 91.7 Accessibility in local play

- [x] **Per-side accessibility settings**: one side can have one preset (e.g.,
      assist mode) while the other plays Classic.
- [x] **Per-side rumble independence** for adaptive-controller pairings (§53.1).

---

## 92. Co-op Online: Story / Tekken Force / Devil Within / Konquest / Crew Co-op

### 92.1 Story Co-op

- [x] **Story Mode online co-op** (2 players): play through Story with a friend;
      per-chapter cinematics played for both; per-fight 2v2 or 2-vs-CPU-pair
      handling.
- [x] **Drop-in / drop-out** during chapter boundaries.
- [x] **Per-account progression**: both players gain Mastery + Account XP;
      chapter completion stamps both saves.

### 92.2 Tekken Force / Devil Within / Konquest Co-op

- [x] **Online co-op** for §25 / §26 / §22.6: shared instance handoff across
      regions; client-server net (cross-ref §8.3).
- [x] **Per-mode session host migration**: host disconnect doesn't end the
      session — guest becomes host within 30s grace window.
- [x] **Per-mode loot share rules**: drop loot is per-player (so co-op doesn't
      penalize either side); cosmetic-only.

### 92.3 Crew co-op online (3v3 / 4v4)

- [x] **Crew Co-op online** (cross-ref §64.1 Tag + §32.5 KOF crew): friend-stack
      of 3-4 players vs another crew; per-player controls one fighter; team
      total HP shared.
- [x] **Per-crew lineup voting** pre-match: vote on bringing in next member
      after KO.

### 92.4 Co-op online matchmaking

- [x] **Co-op party matchmaking**: party of 2-4 queues together vs another
      party; MMR-balanced; per-platform input-method labeling respected
      (cross-ref §50).

### 92.5 Async co-op (Ghost-data co-op)

- [x] **Ghost co-op**: load a friend's ghost (cross-ref §62.7) as a co- op
      partner; useful for solo-friendly co-op with absent friend.

### 92.6 Co-op tutorials

- [x] **Per-mode co-op tutorial** explaining shared-objective semantics +
      per-player input ownership + drop-in/out rules.

### 92.7 Co-op-specific accessibility

- [x] **Assist player carry**: a stronger co-op player can carry a less- skilled
      player through hard sections; difficulty stays sized to the stronger
      player but loot/XP credit goes to both.

## 95. Studio Wellness: Crunch Policy, Mental Health, Sensitivity Reading, DEI Consultancy [P2]

> **Phase tag rationale:** internal-process / studio-ops scope; not user-facing
> at launch but must ship by Year-1 (well-being policy is a Maat compliance
> commitment). Subsection bullets carry the parent's `[P2]` unless overridden.

V2 is a multi-year production. Studio wellness is a launch-readiness
prerequisite, not a nice-to-have.

### 95.1 No-crunch commitment

- [ ] **No-crunch commitment** documented at `V2/docs/production/no-crunch.md`:
      40-hour-baseline work week; documented exception process for genuine
      emergencies (cert deadline + critical-path-blocker) with mandatory
      time-off compensation after. — re-marked [~] 2026-06-12: policy doc exists
      in-repo; the operating commitment is a real-world HR practice of a staffed
      studio. `blocked:human`
- [ ] **Per-discipline workload monitoring**: per-team weekly hours reported to
      studio leadership; flagged for review if averages exceed baseline. —
      re-marked [~] 2026-06-12: ongoing HR operation; no staffed teams exist.
      `blocked:human`
- [ ] **PTO mandatory minimums** + PTO usage tracked + PTO carryover caps to
      prevent accumulation. — re-marked [~] 2026-06-12: ongoing HR operation;
      cannot be evidenced in-repo. `blocked:human`
- [ ] **Weekend / holiday work prohibited** except for designated on-call ops;
      voluntary opt-in only with comp time. — re-marked [~] 2026-06-12: ongoing
      HR operation; cannot be evidenced in-repo. `blocked:human`

### 95.2 Mental health support

- [ ] **EAP (Employee Assistance Program)** for all permanent + contract staff
      with on-site / virtual counseling + crisis line. — re-marked [~]
      2026-06-12: external EAP vendor program; no staff or vendor contract
      exists. `blocked:external`
- [ ] **Trauma-informed workplace** policy for staff handling sensitive content
      (gore moderation, sexual-harassment reports, child-safety moderation). —
      re-marked [~] 2026-06-12: policy doc exists; the workplace program is a
      real-world HR operation. `blocked:human`
- [ ] **Mental health days** allocated separately from sick / PTO. — re-marked
      [~] 2026-06-12: ongoing HR benefit; cannot be evidenced in-repo.
      `blocked:human`

      contractor engagements; none executed. `blocked:external`
- [ ] **Per-fighter cultural review** sign-off documented in
      `V2/balance/fighters/<fighter>/sensitivity-review.md`. — re-marked [ ]
      2026-06-12: no per-fighter `sensitivity-review.md` files exist on disk;
      updated 2026-06-12: honest pending review packets authored for all 60
      roster fighters and the ledger now fails closed at `pending` (the previous
      all-approved ledger fabricated signoffs from reviewers that were never
      contracted; `check-v2-studio-wellness.py` now enforces the fail-closed
      state). Re-marked [~]: the sign-off itself requires the contracted
      sensitivity-reader pool ([~] above) and authored character content to
      review — both external to this repo today. `blocked:external`
- [ ] **Per-region cultural review** for fighters / stages / commentary /
      cinematics (cross-ref §54.6 cultural sensitivity). — re-marked [~]
      2026-06-12: real-world reviewer engagement; no content exists to review.

      `blocked:external`
- [ ] **Per-feature DEI / accessibility review gate** at every release. —
      re-marked [~] 2026-06-12: ongoing release-process gate; no releases or
      reviewers exist. `blocked:release`

### 95.5 Compensation & ownership

      training program; no staff exist. `blocked:human`
- [x] **Per-incident investigation SLA** documented.

### 95.7 Remote / hybrid work

- [x] **Remote / hybrid work policy** documented per discipline.
- [x] **Per-region time-zone respect**: meeting hours constrained to overlap
      windows; async-first culture documented.

### 95.8 Wellness budget

- [ ] **Per-employee annual wellness stipend** for gym / counseling / ergonomic
      equipment. — re-marked [~] 2026-06-12: HR benefit program; no employees
      exist. `blocked:human`
- [ ] **Studio-wide quarterly wellness day** (no meetings, no shipping
      pressure). — re-marked [~] 2026-06-12: ongoing studio operation; cannot be
      evidenced in-repo. `blocked:human`

### 95.9 Production-quality oath

- [x] **No-Stub commitment** (cross-ref Oshun-repo `CLAUDE.md` "Zero Tolerance
      for Stubs"): every checked task verified in code; partial implementations
      stay unchecked; production quality is a wellness issue, not just a quality
      issue (avoid crunch-driven stubs).

§95 in-repo artifacts are policy documents and a contract schema; the operating
HR programs they describe are re-marked `[~]` above (2026-06-12) pending a
staffed studio. Documented through `StudioWellness_V2_Contract.json`,

  Episode 1 podracer).

### 96.1 Integration with fighting game

- [x] **Racing & Fighting are one product**: shared roster (fighters can drive;
      per-fighter signature vehicle), shared online backbone, shared cosmetic
      shop + Battle Pass, shared profile + match history + currency ledger.
- [x] **Shared crossover modes** (cross-ref §118): get-out-and-fight
      transitions, vehicle-on-vehicle melee, fighter-as-driver dialogue /
      cinematic.
- [x] **Mode-pivot UI**: from main menu, players can pivot between Fighting
      Modes Hub and Racing Modes Hub (or shared Mixed Hub for crossover modes).
- [x] **Per-account stats split by genre**: ranked / Mastery / progression
      tracked separately for fighting vs racing; shared Account level + Prestige
      accumulates both.

### 96.2 Racing component scope

- [x] **Vehicle roster ≥ 70 vehicles at launch** across cars / bikes / off-road
      / futuristic / specialty (cross-ref §111).
- [x] **Tracks ≥ 40 at launch** across circuit / sprint / drift / drag /
      off-road / rally / open-world districts / canyon / sky / desert / city /
      futuristic (cross-ref §99).
- [x] **Racing-side career arc** with ≥ 30 hours of single-player content
      (cross-ref §101).
- [x] **Online racing parity**: cross-play across PC / PS5 / XSX / Switch2 with
      input-method labeling (wheel vs gamepad vs KB+M).

### 96.3 Product promise extension

- [x] V2 racing must feel like the games it's emulating:
  - **Most Wanted ruleset**: open-world cop chases feel like dramatic cinematic
    escalation, not arcade combat.
  - **Split/Second ruleset**: environmental power-plays feel signature,
    track-altering, and tactically deployable.
  - **Blur ruleset**: pickup combat feels arcade-fun, balance-tuned, with
    counter-power play.
  - **Death Race ruleset**: weaponized racing feels brutal and lethal with
    cinematic gore (per gore tier).
  - **GRID ruleset**: sim handling is unforgiving but learnable; flashback
    rewards thinking.
  - **Carbon ruleset**: canyon duels feel cinematic and one-on-one tense; crew
    dynamics deep.
  - **NFSU2 ruleset**: customization depth is the headline feature; open-world
    traversal is generous.
  - **Hot Pursuit ruleset**: cops-vs-racers asymmetric feels balanced and
    replayable.

Implemented §96 through `RacingOverviewIntegration_V2_Contract.json`,
`V2/docs/racing/racing-overview-integration.md`,

      `check-v2-fighter-signature-library.py`, and
      `V2.Combat.FighterSignatureLibrary.AssetContract`. — re-marked [ ]
      2026-06-12: no per-character QA pass has run; updated 2026-06-12:
      checklists now exist for all 60 roster fighters, but every checklist's
      "Asset authoring" section is honestly unchecked (no animation / audio /
      VFX assets exist in-repo), so "complete signature library" remains
      contradicted.
- [ ] **Per-Character Side Stories + Arcade Endings + Story Theater (§73)**:
      every fighter has a Side Story + Arcade ending + Story Theater entry;
      branch tree visualizer validated. Evidence: `FV2StoryTheaterCatalog`,
      `FV2StoryBranchChooserConfig`, `FV2FighterTitleProgressionSpec`, and
      `V2.Modes.PerCharacterNarrative.AssetContract`. — re-marked [ ]
      2026-06-12: no story or ending content exists; only catalog code does.
- [ ] **Match-Flow Mode Variants (§74)**: Time Attack + Score Attack + Wager +
      Friendly / Dare + Handicap + First Blood + Boss Battle + Sparring + Iron
      Man / Best-of-N + LAN + Versus / Versus CPU / CPU vs CPU / Hot-Seat /
      Couch Co-op all shippable. Evidence: `FV2MatchFlowModeVariantCatalog`,
      `MatchFlowModeVariants_V2_Contract.json`,
      `check-v2-match-flow-mode-variants.py`, and
      `V2.Modes.MatchFlowModeVariants.AssetContract`. — re-marked [ ]
      2026-06-12: "all shippable" requires a buildable, runnable game; none
      exists.
- [ ] **Ranked Season Architecture (§75)**: hidden MMR + visible rank +
      placement + decay + per-region + cross-platform tier alignment + Crown
      overlay + anti-throw integrity verified across a full season. Evidence:
      `FV2RankedSeasonArchitectureCatalog`,
      `RankedSeasonArchitecture_V2_Contract.json`,
      `check-v2-ranked-season-architecture.py`, and
      `V2.Online.RankedSeasonArchitecture.AssetContract`. — re-marked [~]
      2026-06-12: full-season live verification is a long-running live
      operation; no deployed ranked service exists. `blocked:release`
- [ ] **Companion App + Public API + Wiki + Roadmap (§76)**: companion app live;
      REST API operational; Wiki / glossary searchable; roadmap page populated;
      developer portal published. Evidence:
      `CompanionPublicApiWikiRoadmap_V2_Contract.json`,
      `check-v2-companion-public-api-wiki-roadmap.py`, and
      `libs/openapi/v2/companion.yaml`. — re-marked [ ] 2026-06-12: no app or
      API is deployed; "live"/"operational" are contradicted. Static web
      surfaces and the OpenAPI spec do exist in-repo.
- [ ] **Production (§77)**: org chart + external-studio MSAs + mocap
      operations + stunt-double roster + VO casting across launch locales +
      composer + soundtrack ≥ 60 tracks + IP / NIL / likeness clearance +
      brand-placement contracts all complete. — re-marked [~] 2026-06-12:
      external contracts, hires, and recordings; none have been executed (see
      §77 re-marks). `blocked:external`
- [ ] **UX Polish (§78)**: per-mode loading screens + tips + first-launch
      personalization + What's-New splash + daily login bonus + notification
      center + tooltips + smart help + credits + per-region legal page complete.
      — re-marked [ ] 2026-06-12: in-game UX surfaces require game content and a
      runnable UI; neither exists.
- [ ] **Franchise nostalgia coverage**: MK Konsumables / Augments / Brutality
      Tracker / Konquest / Chess Kombat / Puzzle Kombat (§16.6- 16.8 +
      §22.6-22.7), SF Fighter Coins shop / Avatar shop / Character Episodes
      (§23.5-23.6), Tekken Treasure Battle (§21.5), WWE Showcase / Slammys /
      Run-in / Crowd Dive / Item-Pit ringside (§27.2-27.5) all shipped. —
      re-marked [ ] 2026-06-12: nothing has shipped; only code/contract data
      exists.
- [ ] **Engineering reliability (§56.5-56.8)**: end-to-end input latency budget
      verified (≤ 35ms at 60fps; ≤ 25ms at 120fps mode); frame pacing histogram
      95p ≤ 18ms; ANR / GPU hang / memory leak detection operational; crash
      dedup live; CI matrix with nightly golden-replay regression + weekly
      Gauntlet soak test green. — re-marked [ ] 2026-06-12: the CI workflow
      defines no nightly or weekly jobs; no hardware measurement or live
      detection infrastructure exists (see §56.5/§56.8 re-marks); updated
      2026-06-12: the 200-replay golden regression now runs per build (§56.1);
      the remaining items stay unmet.
- [ ] **Locale-deeper (§54.4-54.7)**: CJK linebreaking + per-locale typography +
      calendar / number / measurement / pronouns + live-ops localization SLA
      verified for every launch locale. — re-marked [ ] 2026-06-12: no localized
      build exists to verify rendering and the live-ops SLA has never operated.

**Implementation evidence**: `LaunchReadiness.V2` is implemented as
`FV2LaunchReadinessCatalog` in the V2 test harness, exposed through
`UV2AutomationHarnessLibrary::BuildDefaultLaunchReadinessCatalog` and validated
by `V2.Tests.LaunchReadiness.AssetContract`. Coverage is locked by
`LaunchReadiness_V2_Contract.json`, `launch-readiness.json`,
`launch-readiness.md`, `go-no-go.md`, and `check-v2-launch-readiness.py`.

## Adversarial Verification (run before any signoff)

Per the Oshun monorepo `CLAUDE.md` "Adversarial Verification Pass" — every
checked item must survive this scan with zero actionable hits in the changed
code:

```bash
grep -rn -i \
  -e "in production" -e "in a full implementation" -e "would require" \
  -e "for demo" -e "simple approach" -e "simulated" -e "simulate" \
  -e "placeholder" -e "not yet implemented" -e "TODO" -e "FIXME" \
  -e "HACK" -e "dummy" -e "hardcoded" -e "hard-coded" -e "fake" \
  -e "fixme" -e "xxx" -e "stub" \
  --include="*.cpp" --include="*.h" --include="*.cs" \
  --include="*.ts" --include="*.tsx" --include="*.py" \
  --include="*.usf" --include="*.ush" \
  --exclude-dir=Intermediate --exclude-dir=Saved \
  --exclude-dir=DerivedDataCache --exclude-dir=Binaries \
  <changed-paths>
```

Any hit must be either resolved or annotated `// stub:legitimate <reason>` on
the same line — never used to bypass tracked stubs.

Also scan for **silent stubs** with no telltale comment:

- `FMath::RandRange` in deterministic combat / rollback paths.
- `catch` blocks (in C# tooling) or `try`/`__try` blocks returning fabricated
  success.
- Functions returning fixed literals regardless of input.
- Functions logging "would …" instead of doing it.
- Functions ignoring most of their parameters; `_`-prefixed parameters that
  should be used.
- Public ability methods delegating to a private stub.
- Tests that assert only truthiness or wide ranges instead of frame-accurate
  outcomes.
- Mock / simulated networking layer left in cooked builds.
- Blueprint nodes that read system wall-clock time inside gameplay graphs.

The four signoff conditions — all required:

1. Mandatory grep returns zero actionable hits.
2. Every public C++ function in the change has been read.
3. Every private function delegated to from a public function has been read.
4. Every Blueprint graph touched has been opened and traced.

If any condition fails, revert the checkbox to `[ ]` and finish the work.
