Diagnose and fix the provided error. This could be a build error, runtime crash, test failure, or a description of unexpected behavior.
Input: $ARGUMENTS
Analyze the input to determine:
If the input is a description rather than an error output, search the codebase for the relevant code.
Read the file(s) referenced in the error. If no file is referenced:
git diff main) that may have introduced the issueRead enough surrounding context to understand the code's intent โ not just the failing line.
Identify the root cause. Common categories:
Sendable conformance violations@MainActor isolation mismatchesHashable/Codable conformance on TrapezioScreenEquatable conformance on TrapezioStatefatalError in unoverridden doWork(params:) or createObservable(params:)Task.sleep)AsyncStream.makeStream() synchronization issuesupdate { }switch blockstrataLaunch capturing stale stateApply the minimal fix that resolves the root cause. Do not refactor surrounding code or make unrelated improvements.
If the fix requires changes across multiple files (e.g., a renamed protocol), update all affected files.
After applying the fix:
