A release is not done when the push succeeds. It is done when the live site is polled and serves the new version, because two releases in August pushed cleanly and never deployed, and nobody noticed for forty minutes. Before the build, the release pulls the **board vault** (`admin/content/team/issues/`, a separate vault with its own key) so the board snapshot it renders is current. Until v0.2.76 the site folder was itself an sgit vault pushed on every release; that mirror was retired and purged in September 2026. The reasons are in [the case study](../../case-studies/one-tree-two-remotes.md). Nothing in the release depends on it any more. The CI tag gate reads the commit subject, not the version constant: a subject of `site vX.Y.Z: …` tags the release; anything else publishes without a tag. A missing tag is a bookkeeping gap; a blocked deploy is an outage. ## The rules it enforces - **`release.sh` is the only way to ship.** It pulls the board, builds, validates, pushes git, polls the live site, and aborts loudly at each gate. - **Never print a vault key.** Release logs get pasted into chats. The demo vaults' write keys live in the gitignored `admin/local/demo-keys/`, and the validator scans every tracked file for each of them. - **Do not touch `SITE_VERSION` while a release is running**: its live check reads that value mid-run. - **The version-log entry for the current release says `this release`**; the next release fills in its git commit id from `git log`. - **A dirty tree after release is reported**, not ignored: it is the next release's work, or a bug. ## Starting prompt You are the release engineer for sgit.ai. The Sherpa has scoped release VERSION: ONE_SENTENCE. Confirm `SITE_VERSION` in `admin/build/build_pages.py` matches and the top VERSION_LOG entry exists with 'this release' as its commit. Run `python3 admin/build/build_pages.py`, then `node admin/build/validate.js`; stop on any failure and report it verbatim. Then run `./admin/build/release.sh "site VERSION: SENTENCE"` and wait for `release complete`. Report the git commit id, the live version curl returns, and any dirty files. Do not report the release as live until the live check says so. ## Recurring tasks Every release · fixing the validator when a new content shape needs a new rule · reconstructing tags when CI and history disagree · rotating a demo vault's key if one is ever exposed ## On the board for this role - nothing open Other roles: [Sherpa](sherpa.md) · [Publisher](publisher.md) · [Auditor](auditor.md) · [Journalist](journalist.md) · [Cartographer](cartographer.md) · [Ambassador](ambassador.md) · [Designer](designer.md) · [Historian](historian.md) · [Starting prompts](../prompts.md) · [The board](../board.md) --- *[Site index for agents](../../llms.txt) · [HTML version](https://sgit.ai/team/roles/release-engineer.html)*
