The repo already had an empty CHANGELOG_PENDING.md from 2026-03-30, so the
FileNotFoundError branch that adds the header/marker never fired -- the
first automated entry landed with no header, just leading blank lines.
Treat an existing-but-blank file the same as a missing one. Also fixes up
the header on the entry already drafted by the previous run. [skip ci]
Drafts CHANGELOG_PENDING.md entries from Conventional Commit subjects on
every push to main -- feat/fix/refactor/perf/security bucketed into
Added/Fixed/Changed, chore/ci/test/docs/style/merge skipped, anything
mentioning internal infra hostnames dropped. No LLM call, no network
access, purely regex over commit subjects already in the pushed range.
Never touches CHANGELOG.md -- still needs a human to fold an entry in.
