Spectrum: Optical

0.0.3

First photon energy layer for Spectrum: Optical.

• Added the LU photon energy model and the shared EnergyStorage interface for storage blocks.
• Added BeamPayload, WavelengthBand, and BeamConsumer so blocks can receive beam parameters through a common contract.
• Migrated beam_receiver to the shared beam consumer contract.
• Added solar_collector: generates photon energy under open sky, affected by time of day and weather.
• Added photon_cell: compact energy storage with configurable output rate, wavelength band, and enabled state.
• Added photon_absorber: accepts an incoming beam from the correct side and transfers energy into adjacent storage.
• Added the multiblock accumulator: accumulator_core and accumulator_wall, with a 3x3x3 structure for increased capacity.
• Added precision_beam_emitter: a configurable beam emitter powered by adjacent photon storage.
• Added texture-free code-drawn GUIs for solar collector, photon cell, accumulator core, and precision beam emitter.
• Added screen handlers for the new energy blocks.
• Added recipes, blockstates, block models, item models, creative tab entries, and localization for the new blocks.
• Precision beam emitter now spends energy according to the beam recalculation interval.
• Precision beam emitter now applies beam world effects just like the regular beam emitter.
• New energy blocks are protected from white beam destruction and red beam ignition.
• New machine GUIs now validate distance and block state through ScreenHandler.canUse.
• Solar collector and photon absorber now skip full adjacent storages when transferring energy.
• Updated README, roadmap, IMPLEMENTED.md, and IN_PROGRESS.md.
• Added the MIT license.

0.0.2

Pre-release stabilization patch for Spectrum: Optical.

• Added an explicit fabric-language-kotlin dependency to fabric.mod.json, so the release jar can launch correctly outside the development environment.
• Fixed beam receiver redstone flickering: receiver active time is now synchronized with the beam recalculation interval.
• Fixed color mixing in the converging lens: RGB channels are now added with clamping, so yellow, purple, and cyan beams correctly trigger their effects.
• Capped focused beam intensity to prevent lens chains from scaling power without limit.
• Spectrum optical control blocks are no longer destroyed by white beams or ignited by red beams at the beam endpoint.
• Fixed blue beam fluid behavior: water freezes into ice, while lava turns into obsidian or cobblestone.
• Separated color effect ranges so base and mixed colors do not trigger multiple effects at the same time.
• Purple beams no longer teleport entities into solid blocks.
• Fixed long beam render culling: beam renderers now render outside the source block entity bounding box.
• Improved cycle protection when lenses recalculate beam paths.
• Added run/ to .gitignore to keep logs, saves, and development cache files out of the repository.
