v1.0.9

Alpha-OSK 1.0.9

Fuzzy / autocorrect overhaul plus a Windows-terminal fix for prediction-pill replacement.

Fixed

• Prediction-pill replace works in Windows terminals — In cmd / PowerShell / Windows Terminal / mintty, Shift+Left moves the cursor without selecting, so picking a prediction left the typed letters at the end of the inserted word (e.g. owen → click Owen produced Owenowen). Detected via foreground window class; terminals now use a BackSpace+type fallback.

Changed

• Removed accessibility profiles. Six profiles (Precise / Normal / Mild–Severe Tremor / Limited Mobility) replaced by one tuned default. Profile UI gone. Picked Gboard-leaning constants: spatial_uncertainty=1.4 (covers diagonal neighbours), confidence_threshold=0.65 (more willing to autocorrect), prediction_weight=0.6, beam-search min_prob=0.001.

Added

• Frequency-weighted fuzzy ranking — candidates ranked by spatial_prob × log(freq + 1) so common words win over rare ones with the same spatial match.
• Edit-distance candidates — fuzzy now catches transpositions (teh → the), deletions (thee → the), and insertions (th → the), not just spatial substitutions.
• Bigram prior on fuzzy candidates — context like of boosts the over thy / tha even when fuzzy returns them in the wrong order.
• Space-time autocorrect — curated misspellings table at data/common_misspellings.txt (~150 entries) plus fuzzy fallback. Runs on space, replaces typed letters atomically. Casing follows the typed word. Privacy mode and edit mode skip it.

Chores

• CLAUDE.md trimmed by ~33 % (release runbook + threat-model table moved to docs/WINDOWS.md and docs/AUTO_UPDATE.md).
