Module ketraterm-render-api

Primitive renderer-facing contracts in io.github.ketraterm.render.api. Its only production dependency is the Kotlin standard library.

Ownership

• TerminalRenderFrameReader, TerminalRenderFrame, and callback sinks define synchronous borrowed reads and primitive row/cluster/cursor copying.
• TerminalRenderImage defines immutable pixels that may outlive a frame; TerminalRenderImageSink delivers borrowed placement geometry and source crops.
• TerminalRenderAttrs, TerminalRenderExtraAttrs, and TerminalRenderCellFlags define the public cell encoding, independently of core storage.
• TerminalColorPalette resolves primary attributes to packed ARGB values and protects its indexed color storage with defensive copies.

Reader implementations own consistency and synchronization. Render cache owns retained copies; UI modules own fonts, layout, shaping, painting, and blink timers.
