A visitor should be able to open the site and start using an assistant without installing software or setting up a room. Over time, they can connect their own devices, contribute idle compute, and use agents for coding, everyday tasks, memory, voice, and data integrations. + +**The direction below remains a product plan; do not infer shipped functionality from it.** The Duga preview now adds a root-page Local assistant, explicit browser-only notes, session activity and an embedded room workspace. Private Net ownership enforcement, public compute and account services remain unimplemented. The underlying runtime is Pooled: a peer-to-peer inference engine, room runtime, coding-agent harness, CLI/API bridge, and OpenClaw integration. Reuse those components where appropriate; do not represent accounts, the Global Net, credits, long-term personal memory, general connectors, or end-to-end voice conversation as implemented today. + +The existing Pooled project expressly commits to *no accounts* and does not plan to open rooms to strangers by default. Duga's initial product also has **no accounts**: use invite links and room codes, preserving the current browser-room experience. Accounts are deferred, not a prerequisite for continuity or device participation. A public compute network still requires a distinct trust boundary and an explicit governance decision; it must not silently change the security model. See [GOVERNANCE.md](GOVERNANCE.md), [roadmap/README.md](roadmap/README.md), and [SECURITY.md](SECURITY.md). + +## Target experience + +1. Visit **duga.app** and get a useful answer immediately. Guest access should not require an account, installing a worker, pairing a device, or donating compute. +2. Use invite links or room codes to connect another device without registration or login. Preserve the existing distinction: invite links grant access to their holders; code-based requests require host approval by default. Cross-device continuity, durable memory and persistent device management remain proposed and must not imply an account service exists. +3. Let users connect their computers and other capable devices through invite links or host-approved room codes. Show availability, capacity, privacy mode, current jobs, and a one-click disconnect/revoke action. +4. Let users ask for coding help, everyday planning and actions, and voice interaction from one assistant interface. Show what an agent plans to do, what it did, and what requires approval. +5. Provide clear, per-task compute choices: **Local**, **Private Net**, or **Global Net**. Do not make network placement an invisible privacy decision. +6. Let users inspect, correct, export, and delete their memories and connected-service permissions. + +An immediate first answer needs a dependable inference route. An active Global Net alone cannot guarantee availability. Plan a clearly disclosed bootstrap route (such as reserved/hosted capacity or a suitable on-device model); measure cost, privacy, and quality before selecting a default. Never silently send a private task to Global Net because a user's devices are offline. + +## Two networks, plus local execution + +| Mode | Compute membership | Intended use | Data rule | +| --- | --- | --- | --- | +| **Local** | The device currently in use | Tasks that fit locally; offline-capable work where supported | No other compute node receives task data. | +| **Private Net** | The user's own devices explicitly admitted through invite links or host-approved room codes | Personal conversations, memories, coding work, and connected-service data | Only the owner's approved devices may act as inference workers. | +| **Global Net** | Opt-in idle devices contributed by participants; shared pool for participants | Tasks whose inputs the user explicitly agrees to expose to untrusted workers | Treat assigned workers as untrusted. No default access to personal memories, connector credentials, or private files. | + +Private Net membership is **the user's own devices only** in the initial product; invite-based teams are out of scope for now. A link or code does not prove ownership: the user must check which devices they admit. An existing Pooled room can include other people and must not automatically be labeled an owned-device Private Net. The current runtime does not enforce device ownership. Global Net is a participant-shared pool, not a free source of secretly enrolled devices. Contributing compute is optional and separate from using the website. The user can choose a mode per task or conversation; the system must visibly explain when a choice changes where data is processed. + +A Global Net worker may see task text, intermediate activations, outputs, model weights, and operational metadata, depending on the job. **Activations are not encryption**: they may reveal prompt content. Do not claim that public nodes cannot learn users' prompts, or that transport encryption makes a public worker trustworthy. If a task includes potentially sensitive content, recommend Local or Private Net. Require explicit, informed consent before sending it to Global Net. Provenance-based blocking of memory/connector data is defense in depth, not a promise that arbitrary pasted text is automatically classified correctly. See [SECURITY.md](SECURITY.md). + +## Execution architecture + +```text +Browser at duga.app + - account-free sessions, invite links/codes, chat, voice, agent activity, approvals + - per-task compute-mode choice, memories and device controls + | +Control plane (new product services, not the Pooled room broker) + - room-scoped admission and proposed device revocation (no account identity) + - presence, capability discovery, job scheduling and quotas + - contribution/usage ledger and abuse controls + - optional encrypted sync and connector authorization + | +Trusted agent orchestrator (user device or explicitly disclosed service) + - plans and routes tasks, enforces tool permissions and budgets + - owns memory retrieval and service credentials + - submits only permitted inference payloads to the selected compute mode + | +Compute/data plane + - Local: one device + - Private Net: owned and paired devices + - Global Net: opt-in, untrusted volunteer workers +``` + +Keep the control plane and inference data plane separate. An admission or scheduling service should not receive conversation plaintext merely because it handles membership or scheduling; whether it does receive plaintext through a specific fallback or hosted orchestrator must be stated truthfully. Never give Global Net workers connector tokens or unrestricted tool execution. Prefer running agent orchestration and sensitive tools in a trusted environment and using remote nodes only for explicitly approved inference jobs. + +The existing Pooled runtime splits **one model's layers** across GPUs over WebRTC; this is different from running several independent agents. Support both patterns deliberately: model-level distribution for a large model, and agent-level delegation only when tasks can be partitioned, measured, and safely combined. Cross-device latency, the slowest worker, and worker churn can make distribution slower than a single device. Implement scheduling and fallbacks based on measured performance rather than assuming more nodes are faster. See [docs/architecture.md](docs/architecture.md) and [README.md](README.md). + +## Agent capabilities and permissions + +- **Coding:** reuse the existing coding harness and isolated preview where it fits. Present diffs and require approval before touching real projects or running consequential code. Keep generated code sandboxed. +- **Everyday tasks:** start with read-only lookup and drafts, then add calendar/email/file changes behind review and explicit confirmation. Maintain an audit trail, cancellation, retry limits, and clear failure states. +- **Memory:** separate transient conversation context from durable, user-visible facts. Request or clearly present proposed saves; support correction, deletion, and scoped retrieval. Never assume a fact inferred by the model is true. +- **Voice:** add microphone permission, speech-to-text, spoken responses, interruption, and visible recording state. Begin with push-to-talk rather than always-on listening. Browser speech synthesis exists in the room, but voice conversation and audio API support are not already complete. +- **Data integrations:** add connectors one at a time with narrowly scoped OAuth or equivalent grants. Store credentials in a trusted boundary, never in prompts sent to volunteer nodes. Show what each connector may read or change, and allow revocation. +- **Multiple agents:** begin with one orchestrator and bounded tool loops. Add specialist/parallel agents only where evaluation shows a benefit, and keep a single authority for permissions, budgets, and final actions. + +Tool results and model output are untrusted. Validate arguments and schemas, isolate execution, bound steps/time/cost, and distinguish a proposed action from an action already performed. Do not automatically execute a volunteer worker's code or recommendations on a user's machine. + +## Contributed-node experience and credits + +A device owner must explicitly opt in to Global Net contribution and retain control over resource limits, allowed hours, idle/battery/thermal behavior, downloads, and immediate stop. A browser tab may contribute while active and supported; a closed or suspended tab is **not** an always-on worker. A future desktop or background node is an optional upgrade, not a prerequisite for using duga.app. + +Use **non-cash contribution credits** initially: earn credits by providing verified work and spend them on Global Net jobs; show earnings, charges, balances, quotas, and job history. Provide a bounded way for guests and newcomers to try the service without first donating compute. Define exact accounting rates after benchmarking and abuse analysis. Do not mint credits merely for claiming idle capacity or self-reported work; account for verifiable completed work, failed jobs, duplicate identities, manipulated results, and disputes. Correct execution by an arbitrary public worker is not guaranteed by the existing Pooled system; redundancy/spot checks and reputation can reduce risk, not prove universal correctness. Do not promise monetary redemption or a trustless economy. + +Public contribution also entails risks for providers: untrusted inputs, model and dependency downloads, disk use, power, heat, bandwidth, and potentially abusive workloads. Constrain jobs and isolate any code execution; do not turn a volunteer inference worker into a general remote shell. + +## Delivery sequence + +1. **Decision record and evaluation baseline:** define account-free session and invitation boundaries, guest inference bootstrap, explicit Global Net consent, data-retention policy, model licenses, target devices, task examples, cost and latency targets. Resolve Duga-versus-Pooled governance before changing core product commitments. +2. **Website-first assistant:** usable guest chat at duga.app with an honest, dependable inference route; responsive UI, streaming, visible privacy mode, and basic session handling. +3. **Private Net:** invite-link/code admission, key and device revocation, an explicit owned-device trust policy, offline handling, local/private routing, and quality/performance comparison against one device. +4. **Useful agents:** coding flow, limited everyday tools, user-controlled memory, push-to-talk voice, and at least one read-only connector. Add approvals and observable execution before write-capable integrations. +5. **Global Net pilot:** explicitly enrolled nodes and opted-in jobs, limited model/job types, admission and scheduling, rate limits, disconnect recovery, privacy warnings, abuse controls, and measured correctness/latency. Start with a restricted cohort, not an open public network. +6. **Credits and scale:** transparent ledger, verified-work policy, allocation fairness, audits, and multi-agent or background-task expansion once the pilot's reliability and security are demonstrated. + +This ordering is a planning recommendation, not a statement that later capabilities already exist. Parallel research is fine, but do not expose high-risk public workloads before the trust model and safeguards exist. + +## Working on this repository + +- Existing building blocks include `engine/` (WebGPU inference), `room.js` and `room/` (P2P room and protocol), `harness/` (Code mode), `cli/` (local compatible API), and `packages/openclaw/` (agent integration). Read [docs/architecture.md](docs/architecture.md), [docs/design/harness-app.md](docs/design/harness-app.md), and [docs/agents.md](docs/agents.md) before modifying them. +- Preserve the existing browser-link room flow and current output-correctness guarantees. Core protocol, peer visibility, dependencies, and model changes require a design note and maintainer review under [GOVERNANCE.md](GOVERNANCE.md). +- Start with tests that match the layer being changed. The existing repository provides `npm test` (Deno unit tests), package tests, and browser/room end-to-end suites; see [package.json](package.json) and [docs/agents.md](docs/agents.md). Record hardware, commit, workload, and baseline for performance claims. +- Keep **implemented**, **proposed**, and **open decision** distinct in code comments, documentation, and the UI. In particular, a Pooled invite link grants bearer access and does not prove device ownership or a persistent identity, and the existing room authentication does not make public volunteer nodes safe for private prompts. + +## Invitation and session rules + +- **Implemented:** a room code locates a room; host approval is required by default. An invite link contains a random secret in its fragment and admits its holder without approval. Returning devices can use a room pass. See [SECURITY.md](SECURITY.md) and [docs/protocol.md](docs/protocol.md). +- **Required direction:** no registration, login, account database, or account-bound device enrollment in the initial Duga product. Keep invite secrets out of logs, analytics and server-visible URLs. Do not treat short room codes as authentication secrets or silently disable host approval. +- **Proposed:** invitation expiry/rotation, per-device removal and durable cross-device continuity need explicit lifecycle and recovery designs before being advertised. Do not claim current links expire or that disconnecting a device revokes its credentials. +- **Privacy:** every admitted inference device is trusted with room data under the existing threat model. Invitations do not make public workers safe for private tasks. Keep Global Net enrollment and task consent separate from room admission. + +## Open decisions requiring explicit agreement + +- What guarantees the guest's first response: on-device inference, reserved hosted capacity, or another clearly disclosed fallback? Who pays for it? +- Which data is synced across devices, where is it stored, how is it encrypted and deleted, and how can users transfer sessions through explicitly approved devices without accounts? +- What work is admissible on Global Net, what exactly does a worker learn, and what verification is sufficient before credits are awarded? +- How do account-free invitations, device ownership, revocation, recovery, rate limits, and Sybil resistance work without degrading the existing account-free Pooled rooms? +- Which first connector and voice stack provide useful UX without leaking credentials or promising unsupported browser background behavior? diff --git a/README.md b/README.md index 7f3c4f17..494368e9 100644 --- a/README.md +++ b/README.md @@ -1,13 +1,13 @@

Set `JAVA_HOME` and `ANDROID_HOME` normally. From the repository root: + +```sh +cargo install naga-cli --version 30.0.1 --locked +npm ci --prefix native/vulkan/oracle +export DUGA_WEBGPU_MODULE=native/vulkan/oracle/node_modules/webgpu/index.js +node native/vulkan/shaders.mjs +node native/vulkan/export-reference.mjs # requires spirv-as and spirv-val +node native/vulkan/capture-oracle.mjs +android/gradlew -p android testDebugUnitTest lintDebug assembleDebug bundleDebug +``` + +Capturing/calibrating the oracle requires a working WebGPU/Vulkan adapter and SPIR-V Tools (`spirv-as`, `spirv-val`; also available in the pinned NDK shader-tools directory through `SPIRV_AS`/`SPIRV_VAL`). CI calibrates both compiled programs against actual WebGPU output on Lavapipe and SwiftShader. Captured floating-point bytes are device-specific. The APK uses the captured synthetic inputs but recomputes its expected output with the original Tint program on the current GPU; every bit mismatch still fails. `syncWebAssets` automatically copies the allowlisted runtime assets, native Android shim and captured oracle; it never copies model weights or repository metadata. + +Outputs: + +- `app/build/outputs/apk/debug/app-debug.apk` — installable development-signed APK. +- `app/build/outputs/bundle/debug/app-debug.aab` — development bundle, not a production/Play Store upload. + +For a SwiftShader emulator, capture its matching software reference and check the native Android binaries: + +```sh +export VK_ICD_FILENAMES="$ANDROID_HOME/emulator/lib64/vulkan/vk_swiftshader_icd.json" +export DUGA_WEBGPU_MODULE=native/vulkan/oracle/node_modules/webgpu/index.js +node native/vulkan/export-reference.mjs +node native/vulkan/capture-oracle.mjs +DUGA_ANDROID_SERIAL=emulator-5554 node scripts/android-native-check.mjs +android/gradlew -p android connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.requireExactVulkan=true +``` + +The script builds Android command-line runners with the pinned NDK, replays all kernel traces on the device and compares every tiny-model logit with original WebGPU execution. It produces test-only GGUF/greedy fixtures for instrumented JNI tests. Those fixtures are included only in the test APK. Instrumentation covers bundled UI, explicit notes, scoped bridge presence, tied/untied JNI decoding, cancellation/reset and missing-model rejection. CI requires oracle status 0; unknown real devices may fail shader equivalence/capability checks and leave Local unavailable. A passed kernel check is not a universal model-quality or physical-phone compatibility guarantee. Android 15/x86_64 SwiftShader passed all twelve kernels, both tiny models and a separate real Qwen3 0.6B three-position comparison (455,808 exact logits). This does not establish physical-phone performance or universal mobile GPU equivalence. + +## GitHub Actions and tag delivery + +[Android workflow](../.github/workflows/android.yml) runs on pull requests, `main`, `feat/duga-android`, manual dispatch, and `android-v*` tags. It: + +1. Compiles the original WGSL to SPIR-V using pinned Naga 30.0.1. +2. Executes the original WGSL on Dawn WebGPU, then requires bit-exact Vulkan parity for twelve kernels and all logits of tied/untied tiny Dense models, separately on Lavapipe and SwiftShader. Exported Tint programs are calibrated against those same captured bytes before they may be used as the on-device oracle. +3. Runs Node packaging/version tests, Java policy tests and Android lint. Boots an Android 15/x86_64 SwiftShader emulator and requires exact device kernel/logit parity plus instrumented JNI/UI tests before delivery. +4. Builds APK and AAB for arm64/x86_64, checks ZIP alignment for 16 KB pages, and uploads them with SHA256SUMS as the `duga-android` Actions artifact. +5. For a distribution tag, signs release APK/AAB, verifies their signatures, then publishes the files to GitHub Releases. Tags with a prerelease suffix create prereleases. Browser/Vercel deployment is unchanged. + +Configure these repository Secrets before distribution: + +| Secret | Value | +| --- | --- | +| `ANDROID_KEYSTORE_BASE64` | Base64-encoded existing release JKS/PKCS12 keystore | +| `ANDROID_KEYSTORE_PASSWORD` | Keystore password | +| `ANDROID_KEY_ALIAS` | Signing alias | +| `ANDROID_KEY_PASSWORD` | Key password | + +A missing signing secret **fails tag delivery**; no unsigned artifact is published as a release. The key is decoded only into runner temporary storage and deleted afterwards. Retain the real signing key outside CI: future updates require the same identity. Signing keys and recovery credentials are kept outside the repository and are never bundled with the app. + +Once the workflow is on the remote branch and signing Secrets are configured: + +```sh +git tag -a android-v0.1.0-preview.1 -m 'Duga Android Vulkan preview' +git push origin android-v0.1.0-preview.1 +``` + +Tag format is validated before signing. `versionName` comes from the tag, and `versionCode` from the workflow run number (monotonic within this workflow). AAB delivery is to GitHub Releases; this does not automatically publish to Google Play. A version tag is not pushed automatically by the coding agent. + +## Invitations, storage and lifecycle + +- Existing room codes retain host approval by default; invite links retain bearer access. `duga://join/ABC234#k=…` opens the app. HTTPS `duga.app/r/…` links are declared **unverified**; Android may leave them in the browser until domain association and signing identity are deliberately configured. Links can always be pasted into Devices. Native asset origins are rewritten to `https://duga.app` for shared room links and QR codes. +- Native calls are origin-scoped to bundled app pages. Inference calls are main-frame only; opaque sandbox previews have no native bridge. External HTTPS pages open in a browser. File/content/intent navigation, cleartext traffic, automatic camera/microphone permissions and app backups are disabled. +- Notes use the app's private WebView profile, separate from browser storage. No account or sync is added. Uninstalling/clearing app data removes notes and downloaded weights. Exports use Android's document picker; copy/share expose no file-read or arbitrary tool capability. +- Configuration changes such as rotation retain the live WebView, conversation and draft in memory. Invitation fragments and WebView history are not saved into instance-state bundles; process death can still lose the session. +- Backgrounding cancels native compute and disconnects the room workspace. App-owned document pickers and share choosers preserve the workspace until they return, including cancellation. Android Back asks before navigating through page history or closing the app. This is a foreground app, not an always-on worker. Chat is ephemeral; room work may need reopening after an interruption. Disconnecting is not credential revocation. + +See [the design and validation record](../docs/design/duga-android.md) for scope and limitations. + +## Manual real-model UI oracle + +For a dedicated emulator with a debug APK installed, `check-model.mjs` can also generate the full chat oracle. Set `DUGA_REAL_GGUF`, `DUGA_REAL_CONFIG`, `DUGA_CHAT_TOKENIZER` and `DUGA_WEBGPU_MODULE` to verified local files; optionally set `DUGA_NATIVE_RUNNER`, `DUGA_ANDROID_SERIAL` and `ADB` to replay every logit through the Android executable. `node native/vulkan/check-model.mjs` writes `native/vulkan/build/chat-oracle.json` and fails on any logit bit difference. Then run: + +```sh +DUGA_ANDROID_SERIAL=emulator-5554 node tests/e2e/android-native-chat.mjs +``` + +This restarts Duga on the dedicated emulator, approves its native-backend confirmation, disables WebView WebGPU, submits the oracle’s prompt through the real UI and requires the exact original answer. The normal pinned-model preparation/download still runs; no model or inference call is mocked. The screenshot is saved under `native/vulkan/build/`. Use hardware GPU acceleration for the real 0.6B test; software GPU chat can take much longer. This manual check is separate from CI’s bounded tiny-model tests. + +To check continuation after backgrounding, save the first `chat-oracle.json` under another filename, then generate a second oracle with `DUGA_CHAT_PREVIOUS` pointing to the first file and `DUGA_CHAT_PROMPT` set to the follow-up. Set `DUGA_CHAT_ORACLE` and `DUGA_CHAT_FOLLOWUP_ORACLE` to those files when running the UI test. It backgrounds/resumes the app between the two exact-answer checks. Generated assistant token IDs stay with the in-memory conversation across GPU model teardown; starting a new chat or deleting chat clears that history. This is transient session handling, not account-based or durable cross-device continuity. diff --git a/android/app/build.gradle b/android/app/build.gradle new file mode 100644 index 00000000..ac6661db --- /dev/null +++ b/android/app/build.gradle @@ -0,0 +1,76 @@ +plugins { + id 'com.android.application' +} + +android { + namespace 'app.duga.android' + compileSdk 36 + + defaultConfig { + applicationId 'app.duga.android' + minSdk 29 + targetSdk 36 + versionCode Integer.parseInt(System.getenv('DUGA_VERSION_CODE') ?: '1') + versionName System.getenv('DUGA_VERSION_NAME') ?: '0.1.0-preview' + testInstrumentationRunner 'androidx.test.runner.AndroidJUnitRunner' + ndk { abiFilters 'arm64-v8a', 'x86_64' } + externalNativeBuild { cmake { cppFlags '-std=c++17 -ffp-contract=off';

The packaged fixture contains the SwiftShader capture’s synthetic inputs and calibration bytes. At runtime, Android obtains expected outputs by executing independently compiled original Tint shaders on the current GPU, then requires bit-exact production Naga output on that same GPU. An Android 15/x86_64 emulator must replay all twelve cases exactly, compare every tiny-model logit against original WebGPU execution and pass instrumented JNI/UI tests before APK/AAB delivery. The new emulator-runner action is pinned to a full commit SHA; it adds a CI dependency and KVM requirement, not an app dependency. Synthetic GGUF fixtures and expected tokens are generated only into test assets and never included in the distributed app. + +Captured bytes remain a driver-scoped calibration baseline. Runtime cross-compiler validation avoids applying a foreign GPU’s numerical results to a new device. Unknown mobile GPUs remain experimental and reject shader/capability mismatches; a kernel self-check does not establish every full-model or browser-driver behavior. Original WebGPU remains development-only; production inference calls direct Vulkan. Prefill is submitted one token per bridge request so slow devices report progress and cancellation instead of timing out a whole prompt batch. + +## Portable original-shader oracle + +`export-reference.mjs` runs original WGSL through pinned Dawn/Tint and exports the programs actually used during that WebGPU execution. It requests core Vulkan 1.1/SPIR-V 1.3 (GLSL450 memory model, without optional Vulkan memory-model, SPIR-V 1.4 or maximal-reconvergence capabilities), assembles them with SPIR-V Tools and validates the result. These profile choices must still reproduce ordinary WebGPU capture bytes exactly during calibration. Only the precompiled SPIR-V is embedded; no Dawn, browser WebGPU implementation, runtime compiler or shader download is included in the APK. This adds build-only SPIR-V Tools and a second generated shader header. + +The native gate executes the exported original program and Naga candidate with identical fixture bytes on the same GPU, restores inputs between executions and rejects every bit difference. All twelve kernels must appear exactly once; reference outputs must be finite, complete and changed from their initial state. This prevents empty/no-op checks from enabling the backend. Captured WebGPU comparisons and full-model tests remain independent CI checks, because sharing the Vulkan wrapper during self-validation alone cannot prove every orchestration or driver behavior. + +Validation: the Lavapipe-exported reference reproduced ordinary captured output on NVIDIA GTX 1080/580.159.04, Mesa Lavapipe/LLVM 19.1.7 and SwiftShader 5.0.0; all twelve cases passed in each of the captured/native, captured/reference and runtime cross-compiler modes. Android with host GTX 1080 also matched all 13,826,176 logits over 91 positions for the complete Duga chat prompt and answer `OK.`. These are correctness checks, not throughput or physical-phone claims. + +## Foreground session recovery validation + +The Android adapter returns exact generated IDs to the assistant controller, which retains them with each in-memory chat turn while the native GPU model is released on backgrounding. A reloaded model prefers these IDs over re-tokenized display text. No new persistent store or account identity is introduced. Context bounds reject prompts with no remaining response budget before prefill. Node tests exercise cancellation, zero-budget rejection and noncanonical tokenization across model reload; the browser integration test checks controller ID retention. + +Android 15/x86_64 with host RTX 2070 SUPER/580.159.04: four instrumented tests passed, including strict device oracle status 0, tied/untied JNI decoding, cancellation/reset, invalid empty-oracle rejection and bundled UI/notes. With WebView WebGPU disabled, the real Qwen3 0.6B UI produced `OK.`, then after background/resume produced `OK.` for a follow-up, both matching original WebGPU. All 13,826,176 logits over the first 91 positions and all 17,168,768 logits over the follow-up’s 113 positions matched exactly through the Android executable. The initial host-GPU emulator used GTX for Vulkan and RTX for GLES and terminated during an activity-lifecycle test; selecting RTX for both allowed the instrumented and two-turn UI checks to complete. CI continues using SwiftShader; no physical phone performance claim follows from these emulators. + +## Signing setup + +The repository’s four Android signing Secrets were initialized for the first Android distribution after checking that no earlier Android release/signing configuration existed.

Actual coding approvals and sandboxed previews remain in the room runtime. The UI adds no analytics and records no invitation secrets in its session activity or persistent notes. Chat remains in tab memory; notes are explicitly persisted under `duga.memories.v1` in localStorage, unencrypted and accessible to same-origin code. Session context already influenced by a note must be discarded with New conversation to remove that influence. + +Validation commands: `npm run test:duga`, `npm run test:e2e:duga`, `npm run test:runtime`, and existing package tests. Browser tests inject a scripted local adapter through request interception, not a production mock switch, and exercise the real UI. They do not establish model quality or real-device GPU performance. The loader's network/cache contracts are tested independently. Real hardware/quality evaluation remains required before a production availability claim. + +## Validation record (2026-10-15) + +- Added seven Node tests: unavailable placement rejection, invitation parsing/secret handling, explicit note persistence/edit/delete, blocked storage, validated model ranges, caching and cancellation. +- Added a desktop/mobile browser suite: streaming, stopping, model failure without fallback, note opt-in, safe text rendering, export/deletion confirmation, invite-secret handling, room/Local compute exclusion and unsupported WebGPU behavior. Passed at 390, 768 and 1440 px widths. +- Full Deno unit suite: 1,415 passed, zero failed, five ignored. Existing headless runtime checks passed. Package tests on Node 22: 212 passed, seven skipped. Existing preview suite: 60/60. Join security: 24 passed; optional CLI and native room-node scenarios skipped because their package-local dependencies are absent. +- Existing Code acceptance suite: 54/55. The failing assertion is “peer has no Code tab before the host starts”. The same failure reproduced in a detached baseline at `7bbf15a`, before the UI implementation; the remainder, including coding edits, approvals, sandbox and peer preview, passed. No change was made to that existing behavior. +- Syntax checks, documentation build (60 pages) and static site assembly passed. Tests used Node 22.23.3 and Deno 2.9.6; browser UI tests used Playwright Chromium 131. No speed/quality claim is made. +- Added `npm run test:e2e:duga-local` to exercise the actual loader and dense engine using synthetic weights. This runner has no WebGPU adapter, so that check was skipped explicitly. Set `E2E_REQUIRE_GPU=1` to make an unavailable adapter a failure on a GPU-equipped validation host. Real-model end-to-end inference and production bootstrap quality are not verified here. diff --git a/favicon.svg b/favicon.svg index 3115280e..31e8a072 100644 --- a/favicon.svg +++ b/favicon.svg @@ -1 +1 @@ -pooled.run \ No newline at end of file +duga.app \ No newline at end of file diff --git a/index.html b/index.html index 5b55ea1a..e4ca3644 100644 --- a/index.html +++ b/index.html @@ -1,349 +1,120 @@ - - - -pooled: pool your devices, run AI together - - - - - - - - - - - - - - - - - - - - - - - - - - + + + Duga · Your devices.

+# Native Vulkan Dense backend
+
+The runtime calls Vulkan 1.1 directly from C++ and compiles into both a Linux oracle runner and Android JNI library. It uses existing WGSL entry-point sources compiled ahead of time to SPIR-V. There is no WebGPU runtime in the native backend. Floating-point contraction is disabled for CPU embedding conversion; shader input layouts, quantization and reduction order are preserved.
+
+`shaders.mjs` pins Naga 30.0.1, emits twelve SPIR-V entry points, an embedded C++ header and source/binary hashes. `vulkan.cpp` owns device selection, coherent buffers, descriptors, pipelines, barriers and fenced submissions. `gguf.cpp` bounds-checks GGUF v3 metadata/tensors; only Qwen3 Dense F32/Q8_0 is admitted. `dense.cpp` implements causal KV caches, QK norm, RoPE, attention, residual/MLP, tied/untied heads and memory/context limits. Large output matrices are split into descriptor ranges that fit the device; computation remains row-equivalent.
+
+Oracle calibration uses actual execution of the original WebGPU sources, never a copy of the native algorithm as the expectation. `export-reference.mjs` exports the independently compiled Tint programs from pinned Dawn 0.6.2, assembles/validates core Vulkan 1.1 SPIR-V, and embeds them alongside the Naga production programs. Android executes both on the same GPU to avoid comparing unrelated drivers’ floating-point outputs. The exported reference is calibrated against ordinary WebGPU captures in CI; kernel equivalence is not a universal proof for all devices, models or browser-specific driver workarounds. All bit differences fail. Absolute/relative errors are diagnostic only. Use one physical GPU at a time; tests make no speed claims.
+

+node native/vulkan/check-model.mjs
+```
+
+Use `DUGA_ORACLE_ADAPTER` (Dawn adapter name) and `DUGA_VK_DEVICE` (native device-name substring) together to select the same physical GPU. Set `VK_ICD_FILENAMES` to a software ICD for deterministic CI. The default is the first adapter in both implementations; explicitly verify reported device names when several GPUs are installed.
+
+Optional real-model check: set `DUGA_REAL_GGUF` and `DUGA_REAL_CONFIG` to locally obtained Qwen3 Dense Q8 files before running `check-model.mjs`. It compares all logits at three fixed input positions. This is not a conversational quality or long-context validation. Checksums, hardware/driver and test scope are recorded in the Android design note. Never treat a passed desktop test as proof for all mobile GPUs.
+
+Oracle modes: default compares Naga against captured WebGPU bytes; `--reference` compares exported Tint against the same bytes; `--on-device` compares Naga against Tint executed on the current GPU. Android JNI uses the last mode. Exactly twelve unique known kernels, non-empty complete output ranges, finite reference values and changed reference outputs are required. Empty or partial fixtures cannot pass. No tolerance, dynamic shader download or WebGPU runtime is introduced.
+
+Set `DUGA_CHAT_TOKENIZER` with a real model to compare the Duga system prompt, full prefill and greedy response (default prompt: `Reply with OK only.`). The original text/tokens are written to `build/chat-oracle.json`, while every logit is still checked exactly. See the Android README for the real native-UI check and test-only Android runners.
