Introduce server-side team-scoped data access enforcement:
- Add TEAM_TO_IVANTI/IVANTI_TO_TEAM mapping to helpers/teams.js
- Add requireTeam() middleware to middleware/auth.js
- Admin bypass (req.teamScope = null)
- 403 for users with no team assignment
- Populates req.teamScope with short and ivanti name arrays
- Ivanti findings: replace client ?teams= param with req.teamScope filtering
on GET /, /counts, /counts/history, /fp-workflow-counts, POST /sync
- Override and note endpoints verify finding is in team scope
- Compliance: add requireTeam() router-level, validate ?team= param against scope
on GET /items and GET /summary
- CARD: validate teamName param on GET /teams/:teamName/assets
- Todo queue: verify findings belong to user's teams on POST /batch
- Clarify IVANTI_BU_FILTER comment (sync-level vs query-time filtering)
- Update 14 test files to include requireTeam in auth middleware mocks
Aggregate /trends, /top-recurring, /category-trend by report_date instead of
per-upload row. Add sibling-upload disclosure to /summary. Filter persistUpload
snapshot query by the upload's vertical to prevent cross-vertical contamination.
Fixes GitLab #12 (reported by nkapur — STEAM active findings chart showed 3
entries for 5/11 after uploading three vertical data sets for that date).
Includes 30 property-based tests covering bug condition and preservation.
