A crash in measure does not carry the original Kotlin call stack through every composition operation. Instead, Compose can build a second, diagnostic path: the compiler leaves source metadata around groups, the runtime stores it, and tooling interprets it later. Compiler markers are breadcrumbs, not a source map Version-specific The pinned compiler lowering accepts collectSourceInformation and traceMarkersEnabled switches.https://learn.staticvar.dev/courses/jetpack-compose-internals/11-tooling-multiplatform-performance-evolution/02-multiplatform-concurrency-boundaries/Mon, 01 Jan 0001 00:00:00 +0000https://learn.staticvar.dev/courses/jetpack-compose-internals/11-tooling-multiplatform-performance-evolution/02-multiplatform-concurrency-boundaries/Evidence legend: Durable marks common semantics; Version-specific marks a pinned source-set implementation; Experimental marks a changing or host-dependent path. “Common code” tells you which algorithm is shared. It does not tell you which lock, atomic primitive, thread identity, or frame host surrounds that algorithm. The safest multiplatform explanation has two layers: first the common contract, then each target’s actual implementation. What is common Durable The common runtime defines the snapshot/composition machinery, an expect-based SnapshotThreadLocal, a synchronization abstraction, and the MonotonicFrameClock interface.https://learn.staticvar.dev/courses/jetpack-compose-internals/11-tooling-multiplatform-performance-evolution/03-benchmark-evidence-is-workload-shaped/Mon, 01 Jan 0001 00:00:00 +0000https://learn.staticvar.dev/courses/jetpack-compose-internals/11-tooling-multiplatform-performance-evolution/03-benchmark-evidence-is-workload-shaped/Evidence legend: Durable marks a measurement principle; Version-specific marks a pinned workload or harness; Experimental marks a comparison that needs controlled reruns. A benchmark number answers a narrow question: how did this named workload behave under this harness? The runtime benchmark module makes that narrowness visible. It measures time, and its base class also records group and slot counts; it does not turn a synthetic tree into an application-wide frame-time promise (ComposeBenchmarkBase.https://learn.staticvar.dev/courses/jetpack-compose-internals/11-tooling-multiplatform-performance-evolution/04-evolution-is-a-reading-workflow/Mon, 01 Jan 0001 00:00:00 +0000https://learn.staticvar.dev/courses/jetpack-compose-internals/11-tooling-multiplatform-performance-evolution/04-evolution-is-a-reading-workflow/Evidence legend: Durable marks a reusable investigation method; Version-specific marks a pinned implementation or release entry; Experimental marks a flag, deprecation, proposal, or transitional path. Compose internals move. Ask each source what it can prove: tests/generated artifacts bound behavior; history explains transitions; release notes establish shipping; design docs preserve historical intent and terminology but may lag; roadmaps show intent only. Use the evidence ladder Use this precedence: pinned implementation → tests/generated evidence → history → release notes → design docs → roadmap.
