Select the execution path matching the user's request:

1. Path A: Static codebase ANR risk audit

When auditing source files or scanning for thread-blocking operations:

Follow references/risk_analysis_guide.md step by step: list candidates, prove the executing thread (trace callers when the thread depends on them), prove the call blocks, then attribute and grade. Report only candidates that pass these checks; list the dismissed ones separately with a one-line reason.
Evaluate off-main-thread mutations of attached Views not merely as crash risks (
```
CalledFromWrongThreadException
```
), but as Sync Barrier Leak ANR risks with their own proof (off-main execution plus an attached View).

2. Path B: Trace-driven diagnosis and remediation

When analyzing ANR traces or stack dumps:

Diagnose systematically using references/trace_analysis_guide.md and format the report with references/anr_trace_report_template.md.
Base findings strictly on log evidence. Propose application fixes only for
```
APP_DEFECT
```
or
```
APP_RESOURCE_OVERLOAD
```
(never for
```
EXTERNAL_BOTTLENECK
```
).
