# Changelog

All notable changes follow [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).

## [0.2.1] - 2026-09-01

### Changed

- Restyle the embedded workbench as a light precision instrument that fits DSH's white conversation canvas.
- Keep semantic navigation legible through a cyan coordinate grid, orange control point, fine technical labels, and restrained borders.
- Reserve lock and version-trail tabs for inline mode because fullscreen already exposes both panels.
- Refresh the README screenshot and interaction GIF from a real DSH Web session.

## [0.2.0] - 2026-09-01

### Changed

- Expand the semantic map directly beneath its DSH answer; fullscreen is now an optional focus mode.
- Use a compact square map and inline tabs for the answer, diff, locks, and version trail.
- Apply a saved preference when a later space exposes the same semantic axes.
- Request reasoning effort `off` only from models that explicitly support it.

### Fixed

- Make the visible cursor itself pointer-draggable with proper capture and release.
- Preserve the original answer when local version history exceeds its storage bound.
- Enforce the 20-lock limit before a request reaches the Host.

### Tests

- Add component coverage for inline DSH mounting and cursor drag commits.
- Add persistence, preference restore, and provider-capability compatibility cases.

## [0.1.0] - 2026-09-01

### Added

- Per-assistant-message “Explore possibility space” action.
- Model-generated semantic axes and a two-dimensional drag map.
- Pointer-release generation with coordinate quantization and deterministic caching.
- Exact quote locks, semantic invariants, and Host-side lock validation.
- Line diff, branching version trail, rollback, copy/select, and saved preferences.
- Chinese and English interface copy with responsive and keyboard-accessible controls.
- Authenticated DSH Host route using the originating answer's model provenance.
- Request limits, concurrency admission, structured-output validation, tests, and CI.
