+## Branch Naming Convention
+
+All branches must follow the `user/<github-login>/<description>` format.
+
+**Get your exact GitHub username first:**
+
+```bash
+if command -v gh &>/dev/null; then
+  LOGIN=$(gh api user --jq .login 2>/dev/null)
+else
+  LOGIN=$(git config github.user 2>/dev/null)
+fi
+if [[ -z "$LOGIN" ]]; then
+  echo "ERROR: Cannot resolve GitHub username."
+  echo "  Option A (recommended): install gh CLI and run: gh auth login"
+  echo "  Option B: set it manually: git config --global github.user <your-github-login>"
+  exit 1
+fi
+```
+
+Never infer from git config `user.name` or email — the org username may differ (e.g. `jsmith-amd` not `jsmith`).
+
+**Create and push a branch:**
+
+```bash
+# Detect the default branch
+DEFAULT=$(git remote show origin 2>/dev/null | awk '/HEAD branch/{print $NF}')
+DEFAULT=${DEFAULT:-master}
+
+git fetch origin
+git checkout -b "user/${LOGIN}/short-description" origin/${DEFAULT}
+git push -u origin "user/${LOGIN}/short-description"
+```
+
+**Description segment rules:** hyphens, underscores, and dots only — no slashes.
+
+- Good: `user/<login>/fix-rdma`, `user/<login>/fix_timeout.v2`, `user/<login>/JIRA-1234-fix`
+- Bad: `user/<login>/fix/rdma` (nested slash), `feat/fix-rdma` (wrong prefix)
+- **ASCII only** — no Unicode, emoji, or special characters
+- **No leading dot** — Git rejects branch names with a leading dot (e.g. `.fix-something` is invalid)
+
+**Allowed prefixes (everything else is blocked at creation):**
+
+| Prefix          | Example                        | Created by       |
+| --------------- | ------------------------------ | ---------------- |
+| `user/<login>/*` | `user/<login>/fix-rdma`       | Developers       |
+| `team/<name>/*` | `team/networking/vlan-rework`  | Teams            |
+| `bot/<bot>/*`   | `bot/ci-bot/fix-pr4521`        | CI automation    |
+| `collab/*`      | `collab/helios-integration`    | Collaborative    |
+| `collab-*`      | `collab-helios`                | Legacy collaborative |
+| `revert-*`      | `revert-abc1234`               | GitHub auto-created |
+| `copilot/*`     | `copilot/fix-bug-123`          | GitHub Copilot   |
+| `dependabot/*`  | `dependabot/npm/lodash`        | Dependabot       |
+
+**Opening a PR:**
+
+```bash
+gh pr create \
+  --head "user/${LOGIN}/short-description" \
+  --title "Short description of change"
+```
