+# 1.3.0 validation · 2026-09-13
+
+## macOS
+
+- Xcode 26.6, macOS 26.6.2; deployment target macOS 15.
+- 29 Swift tests pass, including independent concurrency, strict JSON, local median/spread, cancellation, provider routing, subprocess timeout/cancellation, SwiftData, real Vision OCR, mandatory immersion, rewrite persistence, missing credentials, and Chinese translation submission.
+- Checked the actual native English II preparation and full-screen answer sheet. Chinese text enables Hand In. No live word counter appears.
+- Found and fixed a real legacy Keychain call blocking the UI. Verified the final native Hand In flow immediately displays the missing DeepSeek API Key alert and retains the draft. Submissions now read memory only; explicit persistence/restoration happens in the background using a new data-protection Keychain item. Legacy development items are untouched.
+- Universal arm64 + x86_64 Release build; signature and disk image checks recorded with published artifacts.
+
+## Windows preview 0.1.0
+
+- Built on Windows 11 x64 with .NET SDK 10.0.401. Native WPF executable; self-contained .NET runtime.
+- Actual executable self-test passes median, spread, missing/duplicate reviewers, task scales, bundled rubrics, required JSON properties, serialization, and real Tesseract OCR of the repository's synthetic image.
+- The real WPF preparation view was rendered at 1320 × 840 for visual inspection with an isolated temporary store. This is view rendering, not a manual live network grading test.
+- Eight tasks, independent DeepSeek/Codex configuration, OCR confirmation, history, rewrite and basic statistics implemented. Windows Codex was not logged in on the test host, so no claim of Windows Codex live grading is made.
+
+## Android preview 0.1.0
+
+- Built using the user's installed Android Studio JBR and SDK: Gradle 8.13, AGP 8.13.2, compile/target SDK 35, minimum API 33.
+- Five JUnit tests cover translation directions/scales, Chinese answer aggregation, disagreement, incomplete/duplicate judges, exact correction spans and missing-Key rejection.
+- Signed release APK passes apksigner verification and installs successfully on the Android 15 ARM64 emulator. Native UI inspection results are recorded below after the final check.
+- On-device ML Kit OCR is bundled for Chinese and Latin text. Three real DeepSeek providers are required; no demo grading is in the shipped app.
+
+## Live provider scope
+
+GPT-6 Astra/MAX completed a sample through the actual macOS Swift subprocess service. DeepSeek's official models endpoint was verified with the temporary user-supplied Key. That Key was not committed and has expired. A complete mixed three-provider paid grading session is not claimed as verified; users must enter their own current Key.

+The Windows native OCR dependency requires Microsoft Visual C++ 2015–2022 x64 runtime. If it is absent, install the [official Microsoft redistributable](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist). The application remains usable for typed practice without OCR. No runtime installer executes automatically.
+
+DeepSeek and OpenAI Codex are external, user-configured services. Codex is not bundled, and WriteBench does not redistribute or access its authentication data. Each provider retains its own terms and billing/allowance rules.
+
+Exam names identify supported practice categories. Navigation symbols are original category illustrations or native system symbols, not official exam logos.

+
+Score on a 0–15 practice raw translation scale. This is not a claim of conversion to the CET report score. Translate the source Chinese paragraph into English. Prioritize accurate and complete meaning, appropriate vocabulary and collocation, grammatical correctness, coherent expression and suitable register. Accept natural paraphrases and valid alternative translations. Do not require a writing-task argument, introduction or conclusion. Do not impose an English word limit on the answer.
+
+High performance faithfully communicates essentially all source meaning with clear English and only occasional minor errors. Middle performance communicates the main meaning but has omissions or recurring language problems. Low performance substantially misrepresents or omits source meaning, or contains severe language problems that impede comprehension. Distinguish mistranslation, omission and unsupported additions from harmless stylistic variation.
+
+Diagnostic fields use 0–10: taskCompletion = source meaning and completeness; language = English accuracy and range; coherence = logical flow; register = appropriate tone. corrections.original must appear verbatim in the student's English answer; corrected and improvedVersion must be English. Source omissions go in majorErrors, without fabricated original spans. Produce a full reference translation, not an expanded essay.

+# 考研英语一 · 英译汉翻译练习
+Version: 2026.09-v1. App-owned practice rubric, not an official examiner manual.
+
+Practice scale: 0–10. When the prompt contains five numbered source sentences, evaluate each on 0–2 and sum; otherwise assess the supplied translation task proportionally on the 10-point practice scale and state the scope. Do not pretend a short custom fragment is a complete exam paper.
+

+Version: 2026.09-v1. App-owned practice rubric, not an official examiner manual.

+Use a 0–15 practice scale for a complete English-to-Chinese passage translation. Judge the whole passage; do not apply English I's five-sentence, 2-point-per-sentence scheme. For a custom short fragment, state the limited practice scope rather than representing it as a complete official exam task.
+
+Prioritize accurate meaning, completeness, preservation of relations across sentences, consistent reference, and natural Chinese. Strong translations communicate the passage clearly and faithfully with only occasional minor issues. Material omissions, meaning reversals, invented content, broken logical connections and seriously unclear Chinese substantially reduce the score. Accept valid paraphrases; do not mechanically require word-for-word translation. Do not impose an English word count or essay structure on a Chinese answer.
+
+Diagnostic fields are 0–10: taskCompletion = fidelity and completeness; language = natural Chinese expression; coherence = source relationships and cross-sentence flow; register = appropriate tone. Original correction spans must occur exactly in the student's Chinese answer. corrected and improvedVersion must be Chinese. Explain source omissions in majorErrors when there is no valid original span. Give a full reference translation while accepting multiple correct renderings.

+# WriteBench for Android
+
+Native Android Views / Java 17. A phone layout with exam cards, horizontally scrolling task tabs, a pinned Start button, and a single immersive answering screen. Android 13 or newer.
+
+Supports eight tasks: Kaoyan English I small/large essays, English I/II translation, CET-6 writing/translation, and IELTS Academic Tasks 1/2. All practice uses three independent DeepSeek V4 Pro / MAX graders and local median aggregation. No fake scores and no silent fallback. The API Key lives only in process memory.
+
+Image OCR uses bundled ML Kit Chinese + Latin recognition on-device. Review the original image above editable text, move through pages, and confirm before grading. For a photo containing both question and answer, import it for each purpose and retain only the relevant text in each confirmation step. Diagrams require manually transcribed data. Handwriting accuracy varies; always correct OCR first.
+
+Drafts, complete reviewer JSON, originals, corrected versions and rewrites are stored as atomic JSON files in app-private storage. Rotation preserves an active session; closing the process preserves the draft but clears the API Key. Statistics are a compact summary within History. Codex is available on desktop only.
+
+## Android Studio
+
+Open this folder in Android Studio and allow Gradle sync. This project was built using the user's installed Android Studio JBR and SDK, Gradle 8.13, AGP 8.13.2, compile/target SDK 35. No web runtime.
+
+```sh
+./gradlew :app:testDebugUnitTest :app:assembleDebug
+```
+
+For a signed release, provide your own keystore through environment variables (never commit it):
+
+```text
+WRITEBENCH_KEYSTORE absolute path to a private keystore
+WRITEBENCH_SIGNING_PASSWORD keystore / key password
+key alias writebench
+```
+
+Then run `./gradlew :app:assembleRelease`. The APK is under `app/build/outputs/apk/release/`. The public release uses a stable privately retained release key, not Android's debug certificate.
+
+See [third-party notices](../../THIRD_PARTY_NOTICES.md).

+Version: 2026.09-v1. App-owned practice rubric, not an official examiner manual.
+
+Score on a 0–15 practice raw translation scale. This is not a claim of conversion to the CET report score. Translate the source Chinese paragraph into English. Prioritize accurate and complete meaning, appropriate vocabulary and collocation, grammatical correctness, coherent expression and suitable register. Accept natural paraphrases and valid alternative translations. Do not require a writing-task argument, introduction or conclusion. Do not impose an English word limit on the answer.
+
+High performance faithfully communicates essentially all source meaning with clear English and only occasional minor errors. Middle performance communicates the main meaning but has omissions or recurring language problems. Low performance substantially misrepresents or omits source meaning, or contains severe language problems that impede comprehension. Distinguish mistranslation, omission and unsupported additions from harmless stylistic variation.
+
+Diagnostic fields use 0–10: taskCompletion = source meaning and completeness; language = English accuracy and range; coherence = logical flow; register = appropriate tone. corrections.original must appear verbatim in the student's English answer; corrected and improvedVersion must be English. Source omissions go in majorErrors, without fabricated original spans. Produce a full reference translation, not an expanded essay.

Explain source omissions in majorErrors when there is no valid original span. Give a full reference translation while accepting multiple correct renderings.
