Jira is a native Fleet work-item provider. Fleet's Jira adapter calls the Jira Cloud REST v3 search API on your site, authenticating with an Atlassian API token plus your account email as HTTP basic auth (Atlassian's documented pattern — the token is the basic-auth password, not a bearer token). It polls the configured project for issues updated since the last cursor and normalizes each one into Fleet's common WorkItem shape (summary, status, labels, assignee, URL).
Trigger rules then match over those normalized fields to start a pipeline or dispatch a single agent — the same poll → trigger-rule → agent/pipeline flow as the Linear provider. Jira is configured through the Fleet dashboard, not .fleet/config.yaml: provider type jira, the site URL, project key, and account email are stored in the dashboard, and the API token is fetched at fleet watcher start via FetchIntegrationConfig. The default poll interval is five minutes.
