+# Track changes in php/doc-en and create issues in doc-ja
+# for files that need translation updates.
+#
+# How it works:
+#   - Fetches all commits on doc-en master from the last 7 days
+#   - For each commit, checks if a matching issue already exists in doc-ja
+#   - If not, creates one listing the JA files to update
+#
+# Why iterate commits instead of merged PRs: maintainers sometimes push
+# directly to master without going through a PR (e.g. cherry-picking a
+# contributor's patch). Those changes are real translation work but the
+# PR-based tracker misses them. Walking the commit log catches both cases.
+#
+# Why 7 days: the action runs daily, so 7 days gives us 6 days of margin.
+# Even if the action fails for a whole week, nothing is missed.
+# Duplicates are prevented by searching for the commit SHA (or associated PR
+# number for backward compat) in existing issue titles/bodies.
