# Disable R8 optimization passes. Tree-shaking (unused code removal) still
# runs only method-body rewrites and call-site transformations are suppressed.
#
# Why: CMP 1.11 ships consumer rules with -assumenosideeffects on
# Composer.<clinit>() and ComposerImpl.<clinit>(), plus -assumevalues on
# ComposeRuntimeFlags and ComposeStackTraceMode. These optimization directives
# let R8 rewrite *call sites* (class-init triggers, flag reads) even when the
# target classes are preserved by -keep rules. The result is that the Compose
# recomposer/frame-clock/animation state machines silently freeze on their
# first frame in release builds. -dontoptimize is the only directive that
# disables processing of -assumenosideeffects/-assumevalues. See #5146.

# ---- Compose Runtime & Animation --------------------------------------------
# R8's optimization passes (bundled with AGP 9.x) can inline and dead-code-
# eliminate parts of the Compose frame-clock / recomposer / animation state
# machines, causing every animation to silently freeze on its first frame in
# release builds indeterminate progress spinners, crossfade transitions,
# animateFloatAsState, AnimatedVisibility, etc.
#
# The frame clock lives in compose.runtime, the draw loop in compose.ui,
# and the animation drivers in compose.animation.core. Keep all three so
# R8 does not break the chain.
# Defence-in-depth: prevent R8 tree-shaking of Compose infrastructure classes
# that are referenced indirectly through compiler-generated state machines.
# With -dontoptimize above these are largely redundant, but they provide a
# safety net against future toolchain changes.
