 Compliance scores recorded via `record_attestation` are appended to an on-chain historical log. This allows clients to query the timeline of scores for a given commitment rather than just reading the latest value. Use `get_attestations` to retrieve a list of `AttestationRecord` structures, each containing the attestor address, the compliance score, and the timestamp.
 
+### User commitment readers
+
+The backend first tries `get_user_commitments(owner)` so it can read a user's commitments in one typed call. That reader now returns full `Commitment` records directly from the owner index and intentionally caps the response size with `MAX_USER_COMMITMENTS_READ` to avoid oversized Soroban read payloads.
+
+For compatibility and fallback hydration, the contract also keeps an id-only reader at `get_user_commitment_ids(owner)`. The older `get_owner_commitments(owner)` name remains available as a legacy alias for the same owner index.
