From 3814de5845a3a43ac64c26c4735d728b308c2dfd Mon Sep 17 00:00:00 2001 From: Jordan Ramos Date: Mon, 18 May 2026 15:00:53 -0600 Subject: [PATCH] Fix duplicate chart entries on compliance page when multiple verticals share a report_date MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. --- ...e-duplicate-chart-entries.property.test.js | 1948 +++++++++++++++++ backend/routes/compliance.js | 108 +- 2 files changed, 2036 insertions(+), 20 deletions(-) create mode 100644 backend/__tests__/compliance-duplicate-chart-entries.property.test.js diff --git a/backend/__tests__/compliance-duplicate-chart-entries.property.test.js b/backend/__tests__/compliance-duplicate-chart-entries.property.test.js new file mode 100644 index 0000000..a0280a2 --- /dev/null +++ b/backend/__tests__/compliance-duplicate-chart-entries.property.test.js @@ -0,0 +1,1948 @@ +/** + * Bug Condition Exploration Property Tests: Compliance Duplicate Chart Entries + * + * Spec: .kiro/specs/compliance-duplicate-chart-entries/ (bugfix) + * + * BUG CONDITION (from design.md): + * EXISTS report_date d WHERE COUNT(compliance_uploads WHERE report_date = d) > 1 + * + * Five compliance code paths share the root cause "key by `compliance_uploads.id` + * instead of by `compliance_uploads.report_date`": + * - GET /trends (Property 1, test case 1.A) + * - GET /top-recurring (Property 2, test case 1.B) + * - GET /category-trend (Property 3, test case 1.C) + * - GET /summary (Property 4, test case 1.D) + * - persistUpload() snapshots (Property 5, test case 1.E) + * + * THIS TEST SUITE IS EXPECTED TO FAIL ON UNFIXED CODE. + * Failure of these five test cases is the SUCCESS CASE for the exploration — + * each failure is a counterexample that confirms the corresponding manifestation + * of the bug exists.
