ECC Code Review

Review checklist:

• •Correctness: logic matches requirements; handles errors; no silent failure
• •Readability: naming, small functions, clear invariants
• •Tests: coverage for new behavior; no brittle tests
• •Performance: no obvious N+1, unbounded loops, large allocations
• •DX: helpful logs; clear errors; docs updated if needed

Provide:

• •Must-fix items
• •Nice-to-have improvements
• •Suggested patch/diff if practical
