🗄️ Storage-Rent | Hard Rent-Boundary Assertions across Validator Map Expansions

[Sadeequ]

Dscription

Appending new node entries to storage arrays without validating remaining resource balances can cause updates to fail mid-execution if rent boundaries are violated.

Technical Requirements

• Build a pre-flight rent verification hook inside src/storage.rs.

• Check remaining storage lifetime allocations before writing new data rows, automatically extending ledger parameters if values fall below safety bounds.

Hi maintainer, I’d like to work on this issue.

I understand the problem is that expanding validator/node storage without checking rent limits first can cause writes to fail partway through execution. I’ll focus on "src/storage.rs" and add a pre-flight rent verification step before new rows are appended.

My approach would be to check the remaining storage lifetime/allocation before writes, extend ledger/storage parameters when they fall below the safety threshold, and make sure validator map expansions happen only after the rent boundary is safe.

I’ll also add tests around normal expansion and low-rent boundary cases so the behavior is covered before the storage update happens.
