compose-recomposition-performance

Compose recomposition performance

Router only — deep fixes live in compose-stability-diagnostics and compose-state-deferred-reads.

Two axes

1. Parameter stability / skipping — can Compose skip this restartable composable; are arguments stable and comparable?
2. Where State is read — is frame-rate State read during composition vs layout/draw?

Either axis can dominate; they combine independently.

Route here → focused skill

Primary suspicion	Next skill
Skipping, unstable params, compiler/composables.txt churn	compose-stability-diagnostics
Frame-rate State read phase (composition vs layout/draw)	compose-state-deferred-reads
Evidence for both	Apply both skills in parallel

Review order

1. Decide which axis fits the evidence; open the matching skill.
2. If unclear, sample both — stability churn vs composition-phase reads of fast State.
3. Re-measure after changes.

When NOT to apply

• Recomposition tracks real data changes, or the bug is correctness not cost.
• No profiler / compiler signal suggests a problem.
