This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.","method":"Deterministic executable model with adversarial boundary fixtures.","provenance":{"created_by":"Failure Map","dependencies":"Python standard library","family":"w2-procedural-level-generation-constraints-spawn-points-safe-radius-boundary","generated_at":"2026-09-29T14:50:49.503460+00:00","license":"CC0-1.0","python":"3.12.14","seed":1,"split":"open-access"},"relevance":"Procedural generators silently emit unplayable or unfair levels when a single constraint check uses the wrong boundary, axis, neighborhood or update order; the defect is visible in exact generated geometry.","root_cause":"The safe-radius test rejects cells at exactly min_dist.","sha256":"9542ab05605343c549cede113c19c832fce4a64a85059387020af55f475f51be","title":"Enemy spawn point selection: Spawns at the exact safe radius are rejected · case 01","variant":1,"variant_policy":"Five numbered records share a model and may reuse boundary fixtures.","verified":true,"visibility":"public","verification":{"attempt":{"elapsed_ms":41.958,"exit_code":1,"observations":[{"actual":[[1,1]],"check":"exact safe radius #1","expected":[[0,2]],"passed":false},{"actual":[[3,1],[7,1]],"check":"fault site safe radius boundary #1","expected":[[3,1],[7,1]],"passed":true},{"actual":[[0,0],[3,5]],"check":"regression safe radius boundary #1","expected":[[0,0]],"passed":false},{"actual":[[1,1],[2,4]],"check":"partial repair boundary #1","expected":[],"passed":false},{"actual":[[1,1]],"check":"partial repair boundary #2","expected":[],"passed":false},{"actual":[[1,2]],"check":"diagonal neighbour spawn #1","expected":[[1,2]],"passed":true},{"actual":[[2,0]],"check":"negative index candidate #1","expected":[[2,0]],"passed":true},{"actual":[],"check":"control #1","expected":[],"passed":true}],"passed":false,"stderr":"","stdout":"{\"observations\": [{\"check\": \"exact safe radius #1\", \"actual\": [[1, 1]], \"expected\": [[0, 2]], \"passed\": false}, {\"check\": \"fault site safe radius boundary #1\", \"actual\": [[3, 1], [7, 1]], \"expected\": [[3, 1], [7, 1]], \"passed\": true}, {\"check\": \"regression safe radius boundary #1\", \"actual\": [[0, 0], [3, 5]], \"expected\": [[0, 0]], \"passed\": false}, {\"check\": \"partial repair boundary #1\", \"actual\": [[1, 1], [2, 4]], \"expected\": [], \"passed\": false}, {\"check\": \"partial repair boundary #2\", \"actual\": [[1, 1]], \"expected\": [], \"passed\": false}, {\"check\": \"diagonal neighbour spawn #1\", \"actual\": [[1, 2]], \"expected\": [[1, 2]], \"passed\": true}, {\"check\": \"negative index candidate #1\", \"actual\": [[2, 0]], \"expected\": [[2, 0]], \"passed\": true}, {\"check\": \"control #1\", \"actual\": [], \"expected\": [], \"passed\": true}], \"passed\": false}\n"},"broken":{"elapsed_ms":43.082,"exit_code":1,"observations":[{"actual":[],"check":"exact safe radius #1","expected":[[0,2]],"passed":false},{"actual":[[7,1]],"check":"fault site safe radius boundary #1","expected":[[3,1],[7,1]],"passed":false},{"actual":[],"check":"regression safe radius boundary #1","expected":[[0,0]],"passed":false},{"actual":[],"check":"partial repair boundary #1","expected":[],"passed":true},{"actual":[],"check":"partial repair boundary #2","expected":[],"passed":true},{"actual":[[1,2]],"check":"diagonal neighbour spawn #1","expected":[[1,2]],"passed":true},{"actual":[[2,0]],"check":"negative index candidate #1","expected":[[2,0]],"passed":true},{"actual":[],"check":"control #1","expected":[],"passed":true}],"passed":false,"stderr":"","stdout":"{\"observations\": [{\"check\": \"exact safe radius #1\", \"actual\": [], \"expected\": [[0, 2]], \"passed\": false}, {\"check\": \"fault site safe radius boundary #1\", \"actual\": [[7, 1]], \"expected\": [[3, 1], [7, 1]], \"passed\": false}, {\"check\": \"regression safe radius boundary #1\", \"actual\": [], \"expected\": [[0, 0]], \"passed\": false}, {\"check\": \"partial repair boundary #1\", \"actual\": [], \"expected\": [], \"passed\": true}, {\"check\": \"partial repair boundary #2\", \"actual\": [], \"expected\": [], \"passed\": true}, {\"check\": \"diagonal neighbour spawn #1\", \"actual\": [[1, 2]], \"expected\": [[1, 2]], \"passed\": true}, {\"check\": \"negative index candidate #1\", \"actual\": [[2, 0]], \"expected\": [[2, 0]], \"passed\": true}, {\"check\": \"control #1\", \"actual\": [], \"expected\": [], \"passed\": true}], \"passed\": false}\n"}},"member_only":{"stages":["fixed"],"fields":["implementations.fixed","verification.fixed","harness","repair"],"note":"The verified repair, its recorded checks, the repair description, and the scoring harness are available to members."}}
