Phase 8 — Post-MVP Features, Performance Tuning, and Release Readiness

Purpose

Implement higher-value features and performance optimizations for public release: vertical text improvements, VRAM fine-tuning, OBS integration polish, accessibility, analytics/export, and installers.

Tasks

• 8.1 Vertical text support improvements & tests

  • Files: src/ocr/pipeline.py (enhancements), add vertical-mode toggles
  • Work: Ensure CRAFT + MangaOCR handle vertical text reliably and augment tokenization for vertical segmentation.
  • Tests: tests/test_vertical_text.py with vertical sample images (or mocked pipeline).
  • DoD: vertical text flows correctly in MVP demo.

• 8.2 VRAM-aware scheduling & prioritized model loading

  • Files: src/models/model_manager.py (enhancements)
  • Work: Implement model preemption policy (unload nonessential models when VRAM pressure exists), allow background lazy-loading on idle.
  • Tests: tests/test_preemption.py with simulated VRAM states.
  • DoD: manager evicts models under pressure and reloads on demand.

• 8.3 OBS integration & overlay presets

  • Files: docs/OBS_INTEGRATION.md, src/overlay/presets.py
  • Work: Document how to add overlay browser sources, provide presets for common resolutions and streaming profiles.
  • DoD: streamers can drop-in overlay URL and match expected layout.

• 8.4 Accessibility & localization (UI strings)

  • Files: src/ui/i18n.py, docs/ACCESSIBILITY.md
  • Work: Extract UI strings to a simple i18n file and support at least English/Japanese UI labels. Add keyboard controls and screen-reader notes.
  • DoD: strings externalized and at least one translated sample.

• 8.5 Analytics & anonymized telemetry (opt-in)

  • File: src/core/telemetry.py (opt-in)
  • Work: Add optional opt-in telemetry for crash rates and feature usage (no PII). Document privacy policy in README.
  • DoD: telemetry is opt-in and documented.

• 8.6 Create installers for Windows/mac

  • Files: packaging/windows/, packaging/macos/
  • Work: Use PyInstaller artifacts + installer generation (NSIS or similar on Windows, DMG or notarization notes on macOS).
  • DoD: documented steps to build and test installers.

• 8.7 User testing & bug triage checklist

  • File: docs/USER_TEST_PLAN.md
  • Work: Create a test plan for early users: scenarios, metrics, and bug-report template.
  • DoD: test plan ready and linked from README.

Notes

• Prioritize features with the highest user-impact for the first public release.
