Field Atlas 1.2.0 — prerelease

This is an early-access research build, not a claim that answer quality or bounty
acceptance criteria have been met. The previous stable release remains available.

Changes

• Offline camera/photo/file text extraction and attachment research.
• Refined setup, Library, More, research progress, answer, and source screens.
• Explicit knowledge-catalog refresh and independent pack updates.
• Improved passage relevance, source-only evidence-gap responses, and separation
  of unverified model explanations from supported quotations.
• Citation normalization for parenthesized source references and grouped numbers.
• Native inference stability fixes and one maintained benchmark question file.

Known limitations

• Model-only answers can contain factual errors and ignore length instructions.
  The Japan-history desktop check still failed manual quality review.
• Current downloadable collections are Travel Places and Biology & Longevity,
  not a general encyclopedia. Travel listings can be old or incomplete.
• Retrieval relevance is heuristic. Finding or citing a passage does not prove
  that it supports a claim. Check the actual saved passage.
• Desktop checks use keyword retrieval and do not establish Android/vector-search
  parity, peak device resource use, or multilingual answer quality.
• Model/Biology download recovery and the full connected UI test suite have not
  been independently verified for this release. No new bounty accuracy score is claimed.

Installation

Download fieldatlas.apk and check fieldatlas.apk.sha256. Requires Android 13+
and an arm64 device. Model and knowledge packs are installed separately; queries
run locally after setup. Downloads and catalog refresh require a connection.

The public APK uses the original project release key, matching previous public
releases. It cannot update builds signed with the private local-test key. Do not
uninstall a test build without first preserving its local data.

App version: 1.2.0 (14). GitHub channel: prerelease (v1.2.0-rc.1).

APK SHA-256: 6d688a3632aa77650996aec3ae7ff4e887b7d772d9f2995ea0d8e67b71837b7f.

Verification: JVM tests, Python tooling tests, release build, APK packaging,
reflection retention, and 16 KB ZIP alignment checks. Android UI tests are
compiled, not executed. Detailed limitations are in docs/evaluation.md and
docs/compliance/release-audit.md.
