Summary

Builds on the already merged baseline PR #362. Updates only the Brazilian to European Portuguese plugin and its tests to v1.8.2.

• Add optional local LanguageTool pt-PT checking, disabled by default, after existing deterministic conversion rules. Review-first diagnostics; no generative rewriting.
• Explicit plugin download buttons install pinned, SHA-256-verified LanguageTool 6.6 and a private Eclipse Temurin JRE 21.0.13+9. Portuguese rules are included. No system Java/PATH changes. Licences remain with the distributions.
• Own a loopback-only checker on an available port, automatically started and stopped for checks, including cancellation/window-close cleanup. Optional advanced external-server mode; public LanguageTool cloud endpoints are not supported.
• Add saved alert-group and individual rule selection, a Grammar only preset, and a separate Grammar warnings display filter. Choices apply consistently to preview, batch and grammar rechecks.
• Narrow optional automatic fixes: explicit ele/ela/eles/elas agreement with tem/têm or vem/vêm only. Require enabled agreement rules, matching aligned English subject, installed/enabled MiniLM, meaning safeguards and successful grammar recheck. Both checker modes support this; all other suggestions stay review-only.
• Preserve protected markup, ignored/custom words and cue boundaries. Safe sentence checks reuse existing same-speaker/selection/timing protections; bounded requests and explicit failures retain deterministic output rather than partial optional changes.
• Reposition reference/model controls below top-right actions beside orthography, align dialogue/layout and dictionary right edges, and preserve review space through bounded scrolling.
• Include guarded restrictive-adverb command fixes (Só lembra-te → Lembra-te só), wrapped possessive article protection (do + newline + meu, not do o meu), and resultative anatomical injury wording (ficou lesionada) without rewriting explicit-agent passives.

Validation

• Exact upstream branch: full native-UI suite, 5,475 passed / eight optional integration tests skipped.
• Earlier actual downloaded LanguageTool/Java runtime validation on Linux x64 covered pt-PT findings, startup, normal shutdown and cancellation; published executable also passed a real managed-server batch smoke test.
• Published executable verified S08E02 cues 659 and 305; all 902 cue IDs/timings and source hashes preserved.
• Before subsequent explicit deterministic fixes, grammar-disabled v1.8.1 output matched v1.7.0 across 22 episodes / 18,625 cues.
• Linux self-contained publish and git diff --check pass. Earlier integration CI built all six release targets.

Platform and accuracy limits

Managed runtime execution has only been verified on Linux x64, not Windows/macOS or Flatpak. Native Java packages cover Linux/macOS x64 and ARM64, and Windows x64; Windows ARM64 deliberately uses x64 Java via OS emulation. Actual MiniLM inference was not exercised in candidate-gate tests (deterministic vectors). No full-corpus real LanguageTool accuracy/performance certification is claimed. Grammar checking and auto-fixes remain separate opt-ins.

Rollback

The standalone repository main now contains this version. Its experimental PR is closed. The pre-grammar v1.7.0 tag/release remains available: https://github.com/SMAP-git/BrazilianToEuropeanPortuguese/releases/tag/v1.7.0
