Eve Parity Testing Harness

The parity harness is the shared evidence path for Eve runtimes. It does not try to prove byte-identical pixels. It proves that every runtime is aiming at the same provider-owned CultUI surface: same fixture, same retained tree, same style-token expectations, same control anatomy, and explicit capture gaps.

Authority

• tools/parity/parity-manifest.json owns the fixture matrix, runtime list, and expectations.
• tools/parity/run-parity.mjs owns semantic fixture checks and report generation.
• Runtime capture adapters own screenshots or frame capture for their platform.
• artifacts/parity/latest.md and artifacts/parity/latest.json are reports, not source truth.

The manifest is the cut line. If a fixture or runtime is not in the manifest, it is not part of the parity claim.

Runtime capability manifests are the runtime-owned side of that claim. When a runtime entry has capabilityManifest, the harness validates the JSON document against gamecult.eve.runtime_capability.v1 and cross-checks runtime id, supported features, supported and unsupported plugin declarations, command transport schema, and incubation metadata. The central parity manifest may coordinate split-readiness, but the runtime body must publish the capability claim it expects other repos to consume.

The web reference and Unity UI Toolkit both publish runtime capability manifests. Web uses web/eve-runtime-capability.json to make the browser oracle explicit: it consumes provider advertisements, lowers provider-owned surfaces, emits gamecult.eve.command.v1 intents, and records Chrome headless capture evidence without becoming provider truth. Unity UI Toolkit uses the same path for its sai.vn and norn.graph plugin projection adapter proofs while leaving tex.math as explicit unsupported plugin semantics.

Run

Semantic checks:

powershell -ExecutionPolicy Bypass -File .\scripts\run-parity-harness.ps1

Hard screenshot smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-parity-smoke.ps1

Nightwing owns the Linux Flutter capture body. If its user-local Flutter SDK is missing, install it first:

powershell -ExecutionPolicy Bypass -File .\scripts\install-nightwing-flutter-sdk.ps1

The smoke expands every resizable renderer across the manifest's responsive viewport matrix:

• phone: 390 x 844
• tablet: 768 x 1024
• desktop: 1280 x 720

Device runtimes also capture native physical panel cases when the platform adapter can control orientation without overriding size. Android Flutter currently emits:

• native-portrait: Periwinkle at physical portrait resolution
• native-landscape: Periwinkle at physical landscape resolution

The semantic runner writes:

• artifacts/parity/latest.md
• artifacts/parity/latest.json
• artifacts/parity/<timestamp>/parity-report.md
• artifacts/parity/<timestamp>/parity-report.json
• artifacts/conformance/latest/index.md
• artifacts/conformance/latest/index.json
• artifacts/conformance/latest/packs/*.json
• artifacts/conformance/<timestamp>/...

The conformance export includes conformanceHandoffPath, pointing at the machine-readable EveConformance split map. That handoff is incubation evidence: it names which runner, schema, consumer-smoke, and fixture-corpus paths move when the conformance body leaves Eve.

Handoff documents are also copied into the export under handoffs/*.json. Consumer smokes assert those exported copies, not just Eve-local source paths, so owner repos can inspect plugin, provider, runtime, and conformance handoff maps from the exported pack itself.

The conformance export also carries a gamecult.eve.capability_matrix.v1 projection. It summarizes pack health, plugin ABI/capability claims, provider surfaces/commands/receipts, runtime feature/capture/command coverage, split readiness, and handoff counts. This is derived evidence for consumers, not a new source of truth.

Capability gaps are exported as capabilityGaps[]. They are derived from missing plugin/provider/runtime evidence, declared unsupported plugin projection, capture gaps, and split blockers. Consumer smokes can assert named gap substrings with --expect-capability-gap.

The conformance export includes runtime capabilityManifestPath and capabilityManifestErrors fields so external consumers can distinguish a generic projection runtime from a runtime that can project plugin-declared capabilities.

Plugin handoff paths are exported as plugins[].handoffPath for owner repos such as Sai and Norn. These paths are incubation evidence for where plugin manifest, advertisement, ABI fixture, and conformance ownership must move; they are not plugin runtime state.

The runtime conformance pack is evidence-shaped, not fixture-shaped. Its packs/runtime.json document includes runtimeTargets so runtime repos can consume status, supported features, plugin support, command schema, lifecycle, capture status, and missing evidence without reading Eve's local parity manifest. The runtime-owner consumer smoke asserts EveUnity lifecycle stage status and pending release/test/capture proofs from the exported runtime record, plus release contract fields such as package name, artifact kind, tag pattern, and package root, plus Unity EditMode test runner contract fields such as runner script, package name, test assembly, and platform. Split blockers stay machine-readable instead of hiding in handoff prose.

After generating the parity report, run-parity-harness.ps1 copies artifacts/conformance/latest into artifacts/conformance-consumer-smoke/export and runs tools/conformance/consume-export.mjs against that copied layout. That smoke proves the conformance export can be consumed through its own index and pack files without reading tools/parity/parity-manifest.json.

EveConformance handoff smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-eveconformance-handoff-smoke.ps1

That script validates tools/conformance/eveconformance-handoff.json against the parity manifest and, when present, the generated conformance export. It checks the runner, schema, consumer-smoke, fixture-corpus move sets and the required core/plugin/provider/runtime pack families.

Provider-owned consumer smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-aetheria-conformance-consumer-smoke.ps1

That script runs the same export consumer from E:\Projects\Aetheria and asserts the provider pack, aetheria-world fixture, aetheria provider entry, aetheria-world-command-replay scenario, daemon game/editor surface-kind claims, and provider handoff path. Generated copies remain under Eve's artifacts/aetheria-conformance-consumer-smoke so the provider worktree does not become dirty merely by proving the boundary.

Plugin owner handoff smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-plugin-handoff-smoke.ps1

That script validates the Sai and Norn handoff manifests against their plugin manifests, advertisements, ABI fixtures, move-set paths, contract inputs, and external proofs. It also checks that the manifest and advertisement agree on the runtime-independent executable sidecar boundary: gamecult.eve.plugin_abi.v1, CultMesh/stdio transport, renderer independence, no provider-state mutation, provider-owned command acceptance, and runtime.sidecar process/protocol/schema fields. The plugin-owner conformance smoke also asserts those handoff paths, runtime boundary claims, and exported sidecar fields from the conformance export.

Aetheria provider handoff smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-aetheria-provider-handoff-smoke.ps1

That script validates web/fixtures/aetheria-provider-handoff.json against the provider advertisement and scenario. The handoff names the advertisement, interactive world surface fixture, provider scenario, Eve contracts, forbidden imports, and external proofs that must become Aetheria-owned before the provider pack leaves Eve incubation.

EveFlutter consumer smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-eveflutter-conformance-consumer-smoke.ps1

That script runs the export consumer from flutter/eve_parity and asserts the runtime pack, Sai provider fixture, Flutter runtime targets, and EveFlutter split target without reading tools/parity/parity-manifest.json.

Split-target consumer smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-split-target-conformance-consumer-smoke.ps1

That script asserts that EveFlutter and EveUnity are exported as incubating split targets, that their current split-readiness proofs are passed, and that their graduation blockers remain visible to consumers. A target being present is not enough; future owner repos must be able to consume why it is or is not ready to leave Eve incubation.

The Flutter widget smoke also exercises EveProviderCatalog and EveProviderPicker against a conformance-export-shaped provider list. That is the runtime-side provider picker proof; it consumes provider entries and plugin requirements without reading web fixture paths.

Aetheria Unity package consumer smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-aetheria-unity-package-smoke.ps1

That script checks that Aetheria's Unity package manifest consumes Eve's surface and UI Toolkit packages by file reference, verifies the generated GameCult.Eve.UnityUIToolkit.csproj includes all current Unity runtime source files, then builds the package through Aetheria's Unity-generated project. It is consumer-build evidence, not a replacement for runtime-owned Unity capture or release CI.

Aetheria Unity EditMode test smoke:

powershell -ExecutionPolicy Bypass -File .\scripts\run-aetheria-unity-editmode-tests.ps1

That script temporarily adds org.gamecult.eve.unity-uitoolkit to Aetheria's Unity testables, runs GameCult.Eve.UnityUIToolkit.Tests in Unity batchmode, writes XML and log artifacts under artifacts/aetheria-unity-editmode, and restores Packages/manifest.json before returning. The test asmdef uses Unity-style precompiled references for the Brokkr/CultMesh DLLs that Unity needs to resolve GameCult.Mesh; this complements the normal CultLib .NET/NuGet dependency story rather than replacing it. The runner proves the incubating package test lifecycle, not final EveUnity-owned release or capture. The exported runtime lifecycle records that runner contract so EveUnity can inherit the Unity-specific test proof without making Eve responsible for CultLib package distribution.

Unity runtime lifecycle evidence:

packages/org.gamecult.eve.unity-uitoolkit/eve-runtime-capability.json declares release, test, and capture lifecycle stages for the UI Toolkit runtime. The parity harness validates those lifecycle claims against tools/parity/parity-manifest.json and checks that declared evidence paths exist. The current lifecycle proof is deliberately split:

• release: incubating UPM package identity and import surface exist in Eve;
• test: package-owned EditMode tests run through Aetheria in Unity batchmode, and Aetheria can build the package through Unity's generated project;
• capture: Unity editor or batchmode capture remains a split blocker.

EveUnity split handoff evidence:

powershell -ExecutionPolicy Bypass -File .\scripts\run-eveunity-split-handoff-smoke.ps1

That script validates packages/org.gamecult.eve.unity-uitoolkit/eveunity-split-handoff.json against the runtime capability manifest. The handoff names the package paths, lifecycle stages, Eve contracts, forbidden imports, and external proofs that must become EveUnity-owned before the runtime leaves incubation.

The smoke runner writes:

• artifacts/parity-smoke/<timestamp>/parity-smoke.md
• artifacts/parity-smoke/<timestamp>/parity-smoke.json
• one PNG per target that has a real capture body.

Current Checks

The first pass is semantic and fixture-driven:

• compile local CultUI .eve fixtures;
• load local JSON surface fixtures;
• check provider id;
• check required component kinds;
• check minimum component counts where useful;
• check required style tokens;
• check required bindings;
• check retained slider skins and control parts.
• record the responsive viewport matrix used by screenshot smoke.

This already catches the most embarrassing class of parity lie: a runtime or fixture claiming to render CultUI while the retained tree no longer contains the partitions, bindings, tokens, or slider anatomy the renderer is supposed to lower.

The fixture matrix also includes embedded-surface, which proves that nested CultMesh document slots survive the shared surface contract. The web reference, Flutter parity body, Unity UI Toolkit lowerer, iOS UIKit renderer, and native Android Kotlin dashboard renderer all need to understand surface.slot/embeddedDocuments. Rust participates at the CultMesh document sync layer: it must preserve the same gamecult.eve.surface.v1 slot contract through typed document replication even when it is not painting pixels.

Nested surface support is a required feature for every active GUI runtime in tools/parity/parity-manifest.json. Active runtimes list requiredFixtures: ["embedded-surface"] and supportedFeatures: ["embeddedDocuments"]; the semantic report prints both so a runtime cannot quietly fall out of the contract. Runtime entries also use expectedSourceSymbols for the renderer files that must contain the slot lowering path, so a runtime cannot keep a green body merely because its source file exists. The shared fixture is web/fixtures/cultui-embedded-surface.json, and renderer-specific tests should load that fixture rather than hand-authoring a local substitute.

Runtime Status

The harness tracks every target runtime:

• Web reference: active semantic and screenshot target through Chrome headless using the provider query parameter. Required nested-surface evidence: node --test web\eve-dsl.test.mjs plus the embedded-surface fixture in tools/parity/run-parity.mjs.
• Web responsive layout: Chrome headless emits phone, tablet, and desktop PNGs.
• iOS / UIKit: screenshot target through SSH and EveCanvas' /var/mobile/Library/EveCanvas/capture-request service. Current iOS capture is fixed-device until a simulator or device-resize adapter exists. Required nested-surface evidence: run scripts/run-parity-smoke.ps1 -ProviderId gamecult.eve.embedded-demo against the device target.
• Windows / Flutter: screenshot target through the Flutter parity golden smoke, with phone, tablet, and desktop goldens. Required nested-surface evidence: flutter test --plain-name embedded_surface_fixture_contract plus scripts/capture-flutter-parity.ps1 -FixtureId gamecult.eve.embedded-demo.
• Linux / Flutter: screenshot target through Nightwing over SSH. The smoke stages flutter/eve_parity, runs Flutter goldens on Nightwing, and pulls back phone, tablet, and desktop PNGs. Required nested-surface evidence: scripts/capture-linux-flutter-parity.ps1 -FixtureId gamecult.eve.embedded-demo.
• Android / Flutter: screenshot target through the same Flutter renderer, packaged as a debug APK, installed on Periwinkle through adb, and captured with optional adb shell wm size, orientation control, and adb exec-out screencap; the script restores device size and rotation after each viewport. Required nested-surface evidence: scripts/capture-android-flutter-parity.ps1 -FixtureId gamecult.eve.embedded-demo.
• Android / Kotlin device edge: lightweight native CultMesh dashboard and sensor host. Required nested-surface evidence: android/app/src/main/java/org/gamecult/eve/MainActivity.kt renders surface.slot with a content description containing the embedded slot identity, and node tools/parity/run-parity.mjs reports embeddedDocuments support for android-kotlin.
• Rust / CultMesh: typed document runtime rather than a CultUI renderer. Required nested-surface evidence: cargo test -p cultnet-rs rust_preserves_cultui_embedded_surface_slots_through_typed_document_sync in CultLib.
• Fensalir Direct2D: specialized native target with a runtime-pack gamecult.eve.surface.v1 adapter fixture; runtime-owned command smoke and Direct2D capture are still missing.

Pending runtimes are allowed. Silent fake parity is not.

Next Cuts

1. Add screenshot comparison metrics that score structure, color tokens, bounding boxes, and text presence without pretending byte-identical pixels are the goal.
2. Normalize text scale and font loading across web, Flutter Android, Flutter desktop, and iOS.
3. Give iOS a real vn.stage scene compositor instead of compact stacked fixture lowering.
4. Replace Flutter golden screenshots with native window captures once the Flutter app body can emit a desktop frame without test harness help.
5. Add Direct2D frame capture once the Eve-to-AquariumUiDocument adapter exists.
