Known limits

• No authentication and no per-user permissions.
• The ledger keeps no SOP of its own: nothing is published or adopted until you do it.
• An instruction written into a memo is prose for the next reader. It is not an SOP rule, and there is no SOP text scoped to one operator.
• An outside reference number cannot be withdrawn or corrected.
• Only jobs can carry document requirements.
• Addresses are plain identifier rows. Which address a party uses in which role is not recorded.
• No file deletion and no cleanup of stored files.
• Money is a record for operations, not accounting: no tax filing, no currency conversion, no bank feed, no check against an accounting app.
• One charge line covering several jobs must be split into one line per job by the agent.
• A bill with no lines cannot be waived: it has no charge to judge. Reissue it with a stated total of 0 and the reason.
• A bill recorded without its work links gains them only by a reissue that names them in work.
• A line put on the wrong charge is replaced by 0 and recorded again on the right one; the empty charge stays.
• A settled bill linked to no work, and its payment, appear in no read.
• Parties recorded twice before find_parties existed stay separate.
• No user interface. The server calls no outside system and sends nothing.
