Summary

• Add replay regressions for ordered taps/swipes, stopping at the first command failure, cancellation during a pause, and empty sequences.
• Exercise public APIs with a fake adb binary; no production or dependency changes.
• Leave existing IPv6, timeout-policy, toolchain, and example-dependency PRs untouched.

Validation

• go generate ./...
• go test -race ./...
• go vet ./... and go build ./...
• staticcheck ./...
• golangci-lint run ./... (0 issues) and golangci-lint fmt --diff
• git diff --check
• Mutation check: suppressing replay errors makes failure/cancellation tests fail; restored source passes.
• Replay and event playback statement coverage both reach 100% (overall packages: 69.3% to 71.7%).
