+# Work Items
+
+## Goal
+
+Keep active Jira-linked work in one canonical place so standups, manager updates, and memory syncs can reference each ticket precisely.
+
+---
+
+## Structure
+
+- `index.md`
+  Active index and quick status view.
+
+- `<jira-id>.md`
+  Canonical file for a specific ticket.
+
+---
+
+## Update Rules
+
+- Use one file per active or recently relevant Jira item.
+- Keep titles exact when approved or explicitly confirmed.
+- If the title is not confirmed, store the Jira ID and current framing without inventing a final title.
+- Update the ticket file when scope, sequencing, points, status, rollout implications, or reproducibility meaningfully change.
+- Keep `ai/state/work-items.md` as a short bridge summary, not the primary source of detailed ticket context.
