Rename detection makes `git diff --name-only` report only the destination, so moving a file out of a gated area dropped the source from every filter. A rename of ui/src/a.js to docs/a.js.md emitted all four flags as false, skipping the build for a change that deleted UI source. --no-renames turns the rename back into a delete plus an add, so both paths participate. It is also about 8x faster on a large diff, since rename detection is the expensive part, and it can only ever move a flag from false to true.

# Emits per-area change flags to $GITHUB_OUTPUT so the pipeline can skip work a
|
|
# pull request cannot affect:
|
|
#
|
|
# go - Go sources, module files, linter config, embedded resources
|
|
# js - anything under ui/
|
|
# i18n - translation files and their validation script
|
|
# build - anything that ends up in a binary, image or package (i.e. every
|
|
# change except the doc-only paths in $DOC_ONLY_RE)
|
|
#
|
|
# Only pull requests are narrowed. Master pushes, tags and manual runs always get
|
|
# every flag, so a release can never be built from a partially validated tree.
|
|
#
|
|
# Flags gate STEPS, not jobs: a job-level skip propagates through the needs
|
|
# chain (actions/runner#491) and would take the release jobs down with it.
|

|
|
# Compares HEAD against $BASE_REF (default master). Requires full history

# (fetch-depth: 0 in CI).
