Changes

Campaign and gameplay

• Restored the complete mission-completion chain: save prompt, occupied-slot
  overwrite confirmation, FMV playback and transition to the next mission.
• Preserved the campaign frontier when replaying an earlier unlocked mission.
• Resolved manual-aim ownership conflicts with auto-targeting, retained Gabe's
  final aim heading and restored crouch/diagonal movement behavior.
• Corrected danger-meter release and stabilized enemy weapon drops across the
  original 20 Hz logic and high presentation frame rates.

Rendering

• Restored original MENU.HOG weapon artwork across the pause-menu arsenal.
• Restored both lower-subway bomb models and their resident SPFX textures.
• Fixed subway train and sign corruption by publishing one coherent SCRIM copy
  phase to every affected texture page and bank.
• Restored the virus scanner's amber X-ray presentation, infected-target reveal
  through containers and original status messages.
• Added held weapons to character shadows, stabilized multi-light selection and
  floor/wall projection, and kept emissive lamps at authored brightness.
• Added close-camera fade for Gabe and restored reticle/world-label reveal
  animation. Letterbox bars now appear only during mission introductions.
• Cached unchanged lighting work at the 20 Hz guest tick for steadier 60–240 FPS.

Audio, UI and localization

• Reworked native audio timing and VAB one-shot decoding to reduce latency,
  underruns, skipped samples and restart artifacts.
• Restored the voice-volume preview sound.
• Kept original English optic captions in the Russian pack and prevented
  Russian objective text from leaking into the English interface.
• Added focused regression tests for the new campaign, renderer, bridge,
  localization and audio behavior.

Validation

• Windows MSVC Release build and full non-ROM test suite.
• Windows PsyCross Release build, full non-ROM suite and supported USA v1.1
  ROM probes.
• Release manifest, executable parity, internal/external SHA-256 and
  forbidden-file audit.

Compatibility
