📝 Walkthrough

Walkthrough

The Today sidebar now displays collapsible Pinned, Recent, and Spaces sections. Recent items combine sessions and chats, exclude pinned or archived sessions, sort by activity, and group by day. Spaces can show starred spaces or all visible spaces. Task loading, empty, and retry states are reflected in the sidebar.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to 9f0c1

The sidebar adds collapsible pinned and recent work sections while preserving access to all spaces through the browse control. No concrete merge-blocking risk remains after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 9f0c1

The sidebar reuses existing task APIs and navigation. No new authorization bypass has been established, and ordinary project switching and logout replace the page. Server-side task visibility controls and some asynchronous lifecycle behavior remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The added exposure is automatic retrieval and presentation of task summaries in the existing sidebar, rather than task execution or a new privileged operation. The effective data scope depends on the existing task endpoint's authorization and response filtering; request limits and client-side filters do not establish tenant or asset isolation.

Trust Boundaries and Controls

• observed — The frontend requires team context for pinned reads and team plus user context for recent reads. These guards prevent requests without local context, but projectId, pinned, and created_by remain client-supplied parameters. Backend enforcement of membership, task visibility, and field redaction was not verified.

Resilience and Maintainability Implications

• inferred — Existing full-document navigation on ordinary project/organization switching and logout limits the stale-identity scenario suggested by untagged frontend task state. This counterevidence does not establish protection for every possible identity transition or framework-level late response, so those remain coverage limitations rather than verified PR vulnerabilities.
