| """Private backend for the C1c CI test-report export business CLI. |
| |
| Hand-translated from C1c-escalation-export-L3-001 (branch task_verifier, |
| tasks/new_cases). The mechanism is copied line for line: |
| |
| * exactly one successful complete export per snapshot |
| (complete_export_limit, rejected_export_calls) |
| * the complete export freezes an immutable snapshot and issues one code |
| per failing row; codes are random and are never re-issued |
| * ranged retrieval is bound to that snapshot id and capped at |
| max_range_lines source lines |
| * three call counters and a sha256[:16] fingerprint per issued code, which |
| verifier/score.py reconciles against the model-visible trace |
| |
| Only the business skin differs: this backend exports a monorepo CI test report |
| and issues defect codes, instead of exporting tickets and issuing escalation |
| codes. A CI run is a natural fit for the one-time snapshot rule — reruns |
| reshuffle flaky outcomes, durations and worker assignment, so a second full |
| export would not reproduce the same report. |
