Win Dictation — Changelog

v3.0 — Architecture & UI Rebuild (current)

Single-surface UI

• Replaced 9 separate child windows with one immediate-mode painted surface
• Eliminated inter-window hairline seams at the root
• Widget data model with hover/press animation blending
• Per-monitor DPI scaling (V2)
• Dark mode design tokens
• Dark scrollbar on the transcript edit control

Progress system

• Self-calibrating linear estimator: proc = a + b·audio, fitted per model with decayed online least-squares
• Persisted per-model timing history in win-dictation.ini
• Strictly monotonic countdown (never counts up)
• Smooth percent that eases, never snaps (except final 100%)
• Motion from frame 1 (predicts before whisper reports)

Push-to-talk batch mode

• Removed streaming/VAD/ring-buffer architecture
• Record → stop → single whisper_full call
• 500ms silence auto-end timer
• Physical-core threading (matches the i5 target)

Files

• Added src/timing.h — timing model + progress estimator + persistence
• Rewrote src/main.cpp — single-surface paint, widget model, animation clock, DPI
• Rewrote README.md, src/README.md, src/CHANGES.md

v2.0 — Previous architecture (deprecated)
