AWS CardDemo A-Grade Promotion Gate
Report version: carddemo_a_grade_promotion_readme_v0
This file records the attempt to promote the AWS CardDemo modernization proof from B-grade static/source-oracle parity to A-grade live runtime parity.
Decision
- Action:
do_not_promote - Promotable to A:
False - Current grade counts:
{'A': 0, 'B': 50, 'C': 0, 'F': 0} - Required live legacy runtime matches:
50 - Accepted live legacy runtime matches:
0 - Missing live legacy runtime matches:
50 - Current static/source-oracle status: B=
50, F=0, gaps=0
Rubric Boundary
A-grade is reserved for actual legacy COBOL/CICS runtime traces matched against modern observed behavior for each capability. The existing proof remains B=50/F=0/gaps=0 under the current static/source-oracle rubric.
This is not live COBOL/CICS all-path runtime equivalence.
Replay Command
python tools\evaluate_a_grade_promotion.py --source-root ..\source --out-dir .\final_proof
To test a future live trace corpus, add:
--legacy-trace-dir <path-to-live-trace-json-corpus>
Required Trace Contract
Each accepted live trace record must include the fields listed in A_GRADE_PROMOTION_REPORT.json under legacy_runtime_trace_contract. The key requirements are: pinned source head, live trace kind, matched=true, a capability ID from the ledger, and SHA-256 hashes for the raw legacy trace and modern observation.
