- * @brief Remove credentials pinned to a pseudo-account's owner directory.
- *
- * Cleans up credentials that were linked to a pseudo-account (Vault, LoanBroker,
- * AMM), which such an account can neither accept nor delete. Only credentials
- * are removed; every other object is left in place. The walk visits at most
- * @p maxNodesToDelete directory entries and charges the ones it leaves alone
- * against that budget too, so a directory holding other objects yields fewer
- * than @p maxNodesToDelete deletions. On reaching the bound the result is
- * `tecINCOMPLETE` and the caller must propagate it so a later transaction
- * resumes.
- *
- * @param view Mutable ledger view.
- * @param pseudoAcct The pseudo-account whose directory is cleaned.
- * @param maxNodesToDelete Upper bound on directory entries processed in one call.
- * @param j Journal for diagnostics.
- * @return tesSUCCESS once no credentials remain, tecINCOMPLETE if the bound was
- *         reached, or a deletion error.
