+# Contributing: staged delivery
+
+The normal change path for this repository is **`feature/* → staging → main`**.
+
+1. Create a short-lived feature or fix branch from `staging` and open a reviewed
+   pull request back to `staging`. This includes maintenance, dependency updates,
+   documentation, and agent-authored changes.
+2. Run the repository's required CI and validate the integrated candidate in its
+   lower environment. Record the commit/artifact and smoke or acceptance results.
+   For libraries and documentation, record the applicable package/test/build
+   evidence; a branch name does not establish that a deployed environment exists.
+3. Open a separate promotion PR from `staging` to `main` in this repository.
+   Link the validated candidate, required human approvals, release checklist and
+   rollback plan. A release includes every change in that candidate; unfinished
+   work must stay out or be safely disabled.
+4. Use the existing deployment procedure and verify the running version and
+   relevant user-visible behavior. Branch merges alone do not prove deployment.
+
+Do not direct-push normal work to `staging` or `main`, or open a feature PR
+straight into `main`. An emergency exception requires the approved incident
+process, explicit authorization, exact revision, validation and recovery evidence,
+and subsequent reconciliation into `staging`. A label or a branch called
+`hotfix` does not grant an exception.
+
+When this guide is inherited by another repository, use that repository’s
+explicitly documented `staging` or `qa` integration branch and its existing
+production branch (`main`, or a documented legacy name). Local lane mappings
+take precedence over this repository’s branch names, not over staged review.
+
+## Enforcement and rollout
+
+Where installed, the PR routing workflow checks branch and repository identity. It does not
+verify application tests, approvals, deployed artifacts, or emergency authority.
+A check is mandatory only when GitHub branch protection/rulesets require it.
+Protect both integration and release branches with reviewed PRs, prohibit force
+pushes/deletions, and preserve all existing stronger checks. Require the routing
+check on release branches after the workflow is installed and has run there;
+do not require a check that is not yet available. Review automation that writes
+directly to protected branches before enabling restrictions, and route its
+changes through PRs. Keep emergency bypass access narrow and audited.
+
+Before promotion, reconcile any existing topic PRs aimed at production. Inspect
+their diff against the integration branch before retargeting: changing a PR base
+can change its contents. Do not bulk merge or retarget other contributors' PRs.
+
+The organization standard is documented in the
+[staged delivery guide](https://github.com/GapIntelligence/.github-private/blob/staging/docs/practices/staged-github-flow.md).
+New contributors should walk through their first integration PR and a release
+example with the repository owner; this file is not a training acknowledgment.

+## Staged delivery
+
+- [ ] Feature/fix/maintenance PR targets `staging`.
+- [ ] If this is a promotion to `main`, its source is `staging` in this repository.
+- [ ] Validation evidence identifies the candidate revision/artifact and relevant environment.
+- [ ] Promotion has the required human approvals, release checklist and rollback plan.
+
+For an authorized emergency exception, link the incident, approver, validation
+and reconciliation plan. A checked box or label does not grant an exception.
