# Drone standard — Type A: PyPI package
#
# Canonical pipeline for internal Python libraries that ship a wheel/sdist to
# the private index (dagpipe, doc-forge, hexa, mail-intake, mongo-ops,
# omniread, openapi-first, py-jwt).
#
# Two pipelines ship together:
#   build-and-publish-pypi   — tag-triggered build + quality gate + publish.
#   backfill-pypi-from-tags  — custom-triggered replay of every git tag that is
#                              missing from the index (disaster recovery).
#
# Secrets (Drone): PIP_REPO_URL, PIP_USERNAME, PIP_PASSWORD.
# Copy to <repo>/.drone.yml unchanged; the package name and version are read
# from pyproject.toml, so no per-repo edits are required.
