2. Document who can call them and why

Files To Touch

• contracts/liquidity-pool-contract/src/lib.rs — lines 351, 369

Acceptance Criteria

• Permissionless design documented
• cargo doc passes

Mandatory Checks

• context/ files read
• cargo build passes
• PR references this issue

Hi! I would love to work on this issue to document the permissionless design of distribute_interest and accumulate_interest. This will be one of my very first open-source contributions, and I think it is a great first step for me to get involved in the community!

I have thoroughly reviewed the project's Code Standards and architecture context. My approach will be:

1. Create a dedicated branch following the conventions: feat/document-permissionless-functions.
2. Expand the doc comments for both functions in contracts/liquidity-pool-contract/src/lib.rs (lines 351 and 369) to explicitly state that they are permissionless, explaining who can call them (external contracts like CreditLine, keepers, or any user) and the decentralized architectural reason behind it.
3. Run cargo doc and cargo test locally to ensure the documentation builds perfectly and no standards are broken.
4. Submit the PR referencing this issue and verify that the local checks pass.

I am ready to start as soon as I get the green light!
