 ## Validation
 
 - [ ] Every test method has at least one trait classification (`positive` or `negative` at minimum) — in the report for `report-only` frameworks, or as an attribute for `auto-edit` frameworks
 - [ ] The total equals the per-test inventory count, and displayed trait counts were derived from that inventory
 - [ ] No invented trait values outside the taxonomy table
 - [ ] Existing trait attributes were preserved, not duplicated
 - [ ] The trait summary table was generated
-- [ ] For `auto-edit` frameworks, the project still builds / tests still discover after changes (`dotnet build` / `pytest --collect-only` / `mvn test-compile` / `go vet ./...` / `cargo check --tests` / `npm run test:list` / `Invoke-Pester -PassThru -Skip` / equivalent)
