+# Jira
+
+## Role
+
+- Primary work-tracking system used in Fidelity.
+- Central system for stories, sprint organization, status tracking, and planning flow.
+
+---
+
+## Stable Patterns
+
+- Fidelity-side Scrum work is organized in Jira.
+- Sprint naming uses labels like `PDIAP 26Q1.1`, `PDIAP 26Q2.1`, and `PDIAP 26Q2.2`.
+- Jira is part of the day-to-day delivery flow alongside DSE/daily syncs, sprint review, sprint planning, and retrospectives.
+- Story IDs and approved titles should remain explicit because they are reused in standups, planning, and stakeholder communication.
