+# Why this file exists (issue #351):
+#   Gitea Actions does not correctly disambiguate `paths:` from `tags:`
+#   when both are bundled under a single `on.push` key. The result is
+#   that tag pushes get filtered out and `publish-runtime.yml` never
+#   fires — `action_run` rows: 0. This was unnoticed pre-2026-05-11
+#   because PYPI_TOKEN was absent (publishes would have failed anyway).
+#
+#   Split design:
+#     - publish-runtime.yml         : on.push.tags only        (the publisher)
+#     - publish-runtime-autobump.yml: on.push.branches+paths   (this file — the version-bumper)
+#
+#   This file computes the next version from PyPI's latest, pushes a
+#   `runtime-v$VERSION` tag, and exits. The tag push then triggers
+#   publish-runtime.yml via its tags-only trigger.
+#
+# Concurrency: shares the `publish-runtime` group with publish-runtime.yml
+# so concurrent workspace pushes serialize at the bump step. Without

+# Ported 2026-05-10 (issue #206). Key differences from the GitHub version:
+#   - Gitea Actions reads .gitea/workflows/, not .github/workflows/
+#   - Dropped `environment: pypi-publish` — Gitea Actions does not support
+#     named environments or OIDC trusted publishers
+#   - Replaced `pypa/gh-action-pypi-publish@release/v1` (OIDC) with
+#     `twine upload` using PYPI_TOKEN secret — same mechanism as a local
+#     `python -m twine upload` with a PyPI token
+#   - Replaced `github.ref_name` (GitHub-only) with `${GITHUB_REF#refs/tags/}`
+#     — Gitea Actions exposes github.ref (the full ref) but not ref_name
+#   - Dropped `merge_group` trigger (Gitea has no merge queue)

+# 2026-05-10 (issue #348): originally restored `staging`/`main` branch +
+# `workspace/**` path-filter trigger in PR #349.
+#
+# 2026-05-11 (issue #351): REVERTED the branches+paths trigger from THIS
+# file. Bundling `paths` with `tags` under a single `on.push` key caused
+# Gitea Actions to never dispatch the workflow for tag-push events (0
+# runs in `action_run` for workflow_id='publish-runtime.yml' since the
+# port, including the runtime-v1.0.0 tag — which is why PyPI is still at
+# 0.1.129 despite a v1.0.0 Gitea tag existing).
+#
+# The auto-bump-on-workspace-edit trigger now lives in
+# `.gitea/workflows/publish-runtime-autobump.yml`. That file computes the
+# next version from PyPI's latest and pushes a `runtime-v$VERSION` tag,
+# which THIS file then picks up via the tags-only trigger below.
+#
+# This decoupling means Gitea's path-vs-tag evaluator never has to
+# disambiguate — each file has a single unambiguous trigger shape.

+# PyPI publishing: requires PYPI_TOKEN repository secret (or org-level secret).
+# Set via: repo Settings → Actions → Variables and Secrets → New Secret.

+#     GitHub Marketplace actions; they are installed by Gitea Actions runners and

+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
+#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
