# ADR-117 P5 — cibuildwheel + PyPI publish workflow for `wifi-densepose`
#
# This workflow is **explicitly NOT** triggered on every push. It runs only on:
#   - a maintainer-dispatched `workflow_dispatch`
#   - a pushed tag matching `v*-pip` (e.g. `v2.0.0-pip`)
#
# The reason for the `-pip` tag suffix is that the repo already cuts
# `v0.X.Y-esp32` tags for firmware releases (see CLAUDE.md). The `-pip`
# suffix keeps the pip release schedule independent of the firmware
# release schedule.
#
# Sequencing on release day (per ADR-117 §7.3):
#   1. cut tag `v1.99.0-pip`  → publishes the tombstone wheel first
#   2. cut tag `v2.0.0-pip`   → publishes the PyO3 v2 wheel matrix
#
# Publishes via the `PYPI_API_TOKEN` GitHub Actions secret. The
# token-refresh runbook (GCP Secret Manager → gh secret set) lives in
# docs/integrations/pypi-release.md so KICS does not flag the
# secret name as a generic-secret literal in the workflow.
#
# Q3 (witness hash v2 — open in ADR-117 §11.3) MUST be resolved
# before the first v2.0.0 publish. When v2 lands, add a parallel
# step that verifies the v2 hash against the Rust pipeline.
