Deduplicate (hostname, metric_id) rows across verticals using DISTINCT ON in GET /items, GET /items/:hostname, GET /vcl/stats (heavy-hitters + forecast), GET /mttr, and persistUpload() snapshot block. Add defensive groupByHostname Set and hostname_status CTE for snapshot classification. Includes 38 property-based tests (11 exploration + 27 preservation) covering all six affected sites. Closes #13

|
||
* Bug Condition Exploration Property Tests: Compliance Duplicate Failing Metrics
|
||
*
|
||
* Spec: .kiro/specs/compliance-duplicate-failing-metrics/ (bugfix)
|
||
*
|
||
* BUG CONDITION (from design.md):
|
||
* EXISTS (hostname, metric_id) pair WHERE COUNT(compliance_items rows) > 1
|
||
* across different vertical values (e.g., vertical IS NULL and vertical = 'NTS_AEO')
|
||
*
|
||
* Six compliance code paths share the root cause "missing dedup on (hostname, metric_id)
|
||
* after the multi-vertical migration admitted two-row scenarios":
|
||
* - GET /items (Property 1, Slice 1.A)
|
||
* - GET /items/:hostname (Property 2, Slice 1.B)
|
||
* - GET /vcl/stats heavy-hitters (Property 3, Slice 1.C)
|
||
* - GET /vcl/stats forecast (Property 4, Slice 1.D)
|
||
* - GET /mttr (Property 5, Slice 1.E)
|
||
* - persistUpload() snapshot (Property 6, Slice 1.F)
|
||
*
|
||
* THIS TEST SUITE IS EXPECTED TO FAIL ON UNFIXED CODE.
|
||
* Failure of these six test cases is the SUCCESS CASE for the exploration —
|
||
* each failure is a counterexample that confirms the corresponding manifestation
|
||
* of the bug exists. After the six fixes from design.md are implemented,
|
||
* these same cases will pass and become regression guards.
|
||
*
|
||
* COUNTEREXAMPLE DOCUMENTATION (expected failures on unfixed code):
|
||
* Slice 1.A → failing_metrics contains two 7.1.1 entries (groupByHostname pushes per row)
|
||
* Slice 1.B → metrics array has two (7.1.1, active) entries (no vertical filter, no dedup)
|
||
* Slice 1.C → SUM(heavy_hitters[*].non_compliant) > stats.non_compliant (hostname counted under both teams)
|
||
* Slice 1.D → unclamped blockers = -1 (forecast count inflated by duplicate resolution_date rows)
|
||
* Slice 1.E → SUM(aging[*].total) > COUNT(DISTINCT (hostname, metric_id)) (bucket incremented twice)
|
||
* Slice 1.F → compliant + non_compliant > total_devices (hostname in both columns)
|
||
*
|
||
* **Validates: Requirements 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7**
