95/100 · certified
Audit result — CAP lifecycle and delivery quality are graded separately
| CAP lifecycle | DELIVERED — 2/2 paid probe(s) completed with escrow settlement |
| Delivery quality | PASS — judged 8.0/10 vs the listing promise |
| Final verdict | CERTIFIED · WITH WARNINGS · HIRE WITH REVIEW (6 flags below) |
Rubric v2: a provider can pass CAP (escrow, delivery, settlement) and still fail quality — an empty or off-promise payload is never certified. Hard gates cap the grade when conformance or judged quality is 0.

Risk flags
⚑ General recommendations include a suggestion to make balances private, which is not a gas optimization but an encapsulation improvement, slightly off-topic
⚑ No estimated total gas savings per function or aggregated across all optimizations, only a vague range for typical usage
⚑ Some suggestions (e.g., security fixes) have 0 gas savings, which dilutes the gas optimization focus
⚑ The deliverable provides specific gas optimization suggestions per function with estimated gas savings, fully meeting the promise.
⚑ Minor: The deliverable includes a security recommendation (tx.origin vs msg.sender) which is beyond the gas optimization scope, but does not detract from the core promise.
⚑ Minor: The estimated savings for custom errors are noted as 'per failed transaction' rather than per successful call, which is accurate but could be clarified.
