WARNING

File	Line	Issue
scripts/ci-has-code-changes.sh	N/A	scripts/ directory is included in CODE_PATH_PATTERN, so changes to ci-has-code-changes.sh itself trigger CI — this creates a bootstrapping risk where a broken script can't be tested before it gates CI
lib/recorder-gradle-plugin/src/main/kotlin/io/github/hdcodedev/composegif/plugin/ComposeGifRecorderPlugin.kt	N/A	Regex with DOT_MATCHES_ALL may match across scenario boundaries in parseScenarioNames
scripts/ci-test-summary.sh	109	line_text() is defined but never called — dead code

SUGGESTION

File	Line	Issue
lib/recorder-ksp/src/main/kotlin/io/github/hdcodedev/composegif/ksp/InteractionGestureExpander.kt	109	target = "LEFT" or "RIGHT" is silently ignored for horizontal swipes (falls through to 0.5f); consider logging a warning or documenting this intentional behavior
