## §OIP SYSTEM ARTICLE — HISTORY (2 operations)
A generated article for one OIP shelf. It lists every operation in this API/CLI/MCP/device/model/core subsystem, links each leaf article, and gives the ledger path for proof.

### Read Order
- scan operations
- open a leaf doc
- run via run_now or POST /api/dispatch
- open receipt
- repair/replay if needed

### Operations
- **HISTORY_GET** — How many past turns the build keeps per chat. No args. Returns {convo_max}
  when: Cyrus asks "how many messages do you remember"
  args: none
  doc: https://miscsubjects.com/api/dispatch?key=HISTORY_GET&format=markdown
  run: https://miscsubjects.com/api/dispatch?invoke=HISTORY_GET&share=<TOKEN>
  history: https://miscsubjects.com/api/invocations?object_id=HISTORY_GET
- **HISTORY_SET** — Set how many past turns the build keeps per chat (1-100, default 14). Arg: the number. Takes effect immediatel
  when: Cyrus says "remember more/fewer messages", "keep the last 30"
  args: $1
  doc: https://miscsubjects.com/api/dispatch?key=HISTORY_SET&format=markdown
  run: https://miscsubjects.com/api/dispatch?invoke=HISTORY_SET&body=%3Carg1%3E&share=<TOKEN>
  history: https://miscsubjects.com/api/invocations?object_id=HISTORY_SET

### Troubleshooting
- If a row's example has placeholders, replace only the placeholder values and preserve separators.
- If a call fails, open its receipt and repair it with POST /api/dispatch {key, body, repairs:'inv_ID'}.
- If token scope denies this system, ask the owner for a row:/rows:/pfx: token scoped to the exact operation set.
