What system did Compose actually build?
Six short lessons move from compiler protocol to composition memory, applied changes, UI nodes, and source inspection.
- The compiler/runtime/node pipelineDraw the five boundaries between a composable call and a target UI node.3 min →
- Reading Compose source as evidenceUse declarations, producers, consumers, tests, and history to bound an internals claim.4 min →
- Composition storage is runtime memorySeparate groups and slots used for recomposition from the UI tree they help update.3 min →
- Composition calculates, then applies changesFollow pending operations from composition calculation to an applier-owned target tree.3 min →
- From a node operation to LayoutNodeConnect compiler-facing node operations to the Compose UI tree without equating every composable with a node.3 min →
- Follow one state change through the pipelineUse a controlled composition to distinguish invalidation, recalculation, and applied node updates.3 min →
