| # AWS CardDemo No-Cost Confidence Proof | |
| Report version: `carddemo_no_cost_confidence_readme_v0` | |
| This artifact answers the practical question: how far did we get without paying for or depending on a licensed legacy runtime? | |
| ## Result | |
| - Reviewer posture: `strong_pre_runtime_confidence` | |
| - Ready for pre-runtime review: `True` | |
| - Paid runtime used: `False` | |
| - Public actions allowed: `False` | |
| - Remaining gap: `live legacy COBOL/CICS/VSAM/JCL runtime validation on a real or licensed-compatible runtime` | |
| ## Evidence We Can Produce For Free | |
| - Capability coverage: `50` capabilities. | |
| - Static/source-oracle ready: `50` capabilities. | |
| - Source references attached to capability ledger: `101`. | |
| - Static replay passed: `True`. | |
| - Static replay hash: `912e98e11d46cd967070d06ec17aaed3402bed44026267d1906ea6a2d54b9a42`. | |
| - Golden traces: `34`. | |
| - Edge cases: `40`. | |
| - Clean-copy/API smoke evidence is recorded in `FINAL_RECEIPT_SUMMARY.json`. | |
| ## Legacy Source Runtime Shape | |
| - COBOL programs scanned: `44`. | |
| - CICS programs: `25`. | |
| - Non-CICS COBOL programs: `19`. | |
| - Free GnuCOBOL probe candidates: `17`. | |
| - Programs still requiring mainframe-compatible runtime for honest execution: `27`. | |
| ## A-Grade Boundary | |
| - A-grade decision: `do_not_promote`. | |
| - Promotable to A: `False`. | |
| - Accepted live runtime matches: `0`. | |
| - Missing live runtime matches: `50`. | |
| This does not pretend to be live COBOL/CICS equivalence. It shows that the unpaid work is strong and that the remaining proof step is specifically live legacy runtime validation. | |
