Added

• Updated the mod for Minecraft Fabric 26.2 and Java 25.
• Added separate client and common/server source sets.
• Added server-authorized spell-paper opening and spell saving.
• Added bounded networking with stroke, point and coordinate validation.
• Added server-side rate limiting for spell parsing.
• Added normalized drawing coordinates for consistent recognition across resolutions.
• Added Undo and Redo controls to the drawing screen.
• Added eraser mode and a parser debug overlay.
• Added improved mathematical circle fitting for spell-ring detection.
• Added structured spell states: Invalid, Draft, Prepared and Active.
• Added typed spell data containing elements, signs, states and display names.
• Added persistent stored-spell components to spell-paper items.
• Added configurable server settings through wha-magic-server.json.
• Added separate element effects and manifestation modifiers.
• Added temporary and safer Earth-magic block changes.
• Added initial automated parser and fixture-test infrastructure.
• Added proper MIT licensing and third-party attribution.

Changed

• Reworked spell parsing into a server-authoritative system.
• Reworked ring detection to measure circularity, completeness, gaps and fitting error.
• Reworked symbol segmentation so signs are grouped into separate candidates.
• Improved recognition of signs drawn at different positions and rotations around a ring.
• Replaced string-based compiled spells with structured spell state and semantic data.
• Spell Paper now stores its original drawing alongside its compiled spell information.
• Spell Paper is now limited to a stack size of one.
• Active and prepared spells now display their state and recognized contents in their item name and tooltip.
• Refactored spell execution so elements and manifestations can be expanded independently.
• Moved client-only drawing code out of the common/server source set.
• Removed the older unused Cloud, Unistroke and Symbol recognizers.

Fixed

• Fixed spell-paper screens being opened directly from common item code rather than through authorized networking.
• Fixed spell saving potentially updating the wrong hand.
• Fixed unbounded drawing packets potentially placing unnecessary load on the server.
• Fixed drawing outside the canvas producing invalid coordinates.
• Improved rejection of squares, lines, zigzags and other false spell rings.
• Improved recognition of large and multi-stroke core sigils.
• Improved separation of multiple signs placed around the same ring.
• Reduced incorrect recognition between element sigils and manifestation signs.
• Reduced parser logging spam during normal drawing.
• Improved persistence of spell drawings across reopening and world reloads.
• Improved safety around temporary Earth-magic terrain changes.

Known Issues

• True multi-sigil and multi-element spells are not currently supported. Multiple inner sigils are combined and interpreted as one core sigil, usually resulting in an “Unrecognized Core Sigil” warning.
• Some combined manifestation signs may be recognized correctly but only one manifestation currently controls the final spell execution.
• Automated gesture fixtures are still limited and need real recorded drawings for reliable regression testing.
