The F-Droid device review found that a German local rewrite became English and changed 13 uhr to 13:00. This branch gives local models source-language cues, rejects clear translation and number/script drift before saving, and retries some failed rewrites in the source language. Mixed-language drafts can retry by passage. It also rejects a newly observed English rewrite that silently drops an explicit missed-meeting constraint, ignores silence-only dictation, and asks users to compare each result with the original before sending.

Local models are best effort. The app and release criteria do not promise perfect meaning preservation, equal quality in every language, strong tone changes, or a speed guarantee. The phone tests show why: Gemma and Qwen kept the reviewer's German sample in German, but a Japanese Gemma output changed who could attend a meeting; English Casual and Professional were sometimes indistinguishable; Qwen and Llama dropped facts in other runs. The app rejected several of those outputs, but its checks are not a general semantic verifier. Llama 3B took roughly two minutes and also lost meaning in one run.

On Redmi 12 / Android 15, the isolated QA app completed encrypted backup export and settings-only restore, local WebDAV sync and conflict review, and a mock OpenAI-compatible cloud stream. Spoken dictation captured and inserted the user's words but heard “Thursday” as “Lutersday.” Android registered the selected-text handler, but this phone's selection menu did not show Rescripto, so return-to-caller remains unverified. Real cloud and Nextcloud accounts were not used. See docs/FDROID_DEVICE_RETEST.md and testing/mobile/reports/2026-10-25_fdroid_language_retest.md for exact outputs and limits.

Validation: Flutter 3.44.9 reports 476 passing tests and clean analysis; an Android arm64 release-style APK builds. This PR remains draft. No release tag, signed APK, reproducibility comparison, or F-Droid recipe update has been published.

Manual Release workflow preflight passed on commit 54b08b2: run 40485716462. Its unsigned APK artifact is available; no signing or publication occurred.
