| # Auto-tag a release after the version branch merges to main / main-v*. | ||
| # | ||
| # Sandbox naming convention while we're still validating the logic on | ||
| # real release merges. Once we've seen a few clean dry-runs, this gets | ||
| # renamed to `auto-tag-release.yml` and the dry-run guard comes out. | ||
| # | ||
| # Two trigger paths: | ||
| # | ||
| # - `push: branches: [main, 'main-v*']` — fires automatically on every | ||
| # merge to a release line's main branch. Always dry-run. Logs the | ||
| # decision; does not push the tag. Use this output to confirm the | ||
| # workflow picks the right SHA + version before we flip the switch. | ||
| # | ||
| # - `workflow_dispatch` with `dry_run` input (default `true`). Set to | ||
| # `false` to actually push the tag. Use this when the push-triggered | ||
| # dry-run printed the right answer and you want to commit to it. | ||
| # | ||
| # Safety properties: | ||
| # | ||
| # - Version gate: skips silently if `apollo-router/Cargo.toml`'s version | ||
| # at the target SHA matches HEAD~1's version — i.e., no actual release | ||
| # to tag. | ||
| # | ||
| # - Idempotency: if the tag already exists at the right SHA, skip | ||
| # silently. If at the wrong SHA, error loudly and refuse to retag. | ||
| # | ||
| # - SIGPIPE-safe under `set -euo pipefail` (no `... | head -1` against | ||
| # potentially-long git output). | ||
| # | ||
| # - PAT scoped: uses `APOLLO_BOT2_GITHUB_PAT` so the tag is attributed | ||
| # to apollo-bot2 and bypasses tag-creation rules. | ||
