Description
Audit finding **C1 — theoretical, LOW-MEDIUM**.
`AndroidProfiler` computes `timestampDiff` (the elapsedRealtime↔wall offset) once at profile end and applies it to every wall-stamped `PerformanceCollectionData` sample (`sentry-android-core/src/main/java/io/sentry/android/core/AndroidProfiler.java:309-324`). A wall step during the profile shifts all earlier CPU/memory samples relative to the trace.
Source: [JAVA-557]() §C1.

Read AndroidProfiler.java at lines 309-324 and trace how timestampDiff is computed at profile end and applied to PerformanceCollectionData samples. Verify the behavior around a wall-clock step during profiling, then ensure earlier CPU and memory samples are not shifted relative to the trace; confirm the corrected timestamp alignment with the relevant profiler coverage.
