## §OIP SYSTEM ARTICLE — TRAIL (3 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
- **TRAIL_SAVE** — Name a sequence of past invocations as a TRAIL - a named sequence of past calls you can run again as one unit 
  args: name|inv_ID1,inv_ID2,... (2-20 receipt ids, oldest first, comma-separated)
  doc: https://miscsubjects.com/api/dispatch?key=TRAIL_SAVE&format=markdown
  run: https://miscsubjects.com/api/dispatch?invoke=TRAIL_SAVE&body=morning-report%7Cinv_abc123%2Cinv_def456&share=<TOKEN>
  history: https://miscsubjects.com/api/invocations?object_id=TRAIL_SAVE
- **TRAIL_RUN** — Run a named TRAIL (a saved sequence of past calls). Every recorded step is checked again against the caller's 
  args: name (the trail name given to TRAIL_SAVE)
  doc: https://miscsubjects.com/api/dispatch?key=TRAIL_RUN&format=markdown
  run: https://miscsubjects.com/api/dispatch?invoke=TRAIL_RUN&body=morning-report&share=<TOKEN>
  history: https://miscsubjects.com/api/invocations?object_id=TRAIL_RUN
- **TRAIL_LIST** — List the trails in your own space - owner, token, or tenant; trails never cross spaces.
  args: (none)
  doc: https://miscsubjects.com/api/dispatch?key=TRAIL_LIST&format=markdown
  run: https://miscsubjects.com/api/dispatch?invoke=TRAIL_LIST&share=<TOKEN>
  history: https://miscsubjects.com/api/invocations?object_id=TRAIL_LIST

### 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.
