 - **Empty result** → exit 0 with `No eligible candidates for <scope> in state(s) [...]`. Usually means `--state` doesn't match the scope's real state names, or the scope is empty.
 - **`--page-size 0` (or any non-positive integer)** → exit 1; `--concurrency-ceiling` likewise must be a positive integer.
 - **Portfolio-held candidates** are excluded before planning (the human/JSON output reports how many were held).
+- **Triage-prep sheets are ephemeral.** `--triage-prep` writes `triage-prep-evidence.json` under the current `--out-dir` (or generated run directory), fetches every configured repository's fresh `origin/main`, and adds one read-only pointer to the prompt. It never attaches the sheet or writes a disposition to Linear. Use repeatable `--triage-prep-repo <key=url>` flags or `SYMPHONY_TRIAGE_PREP_REPOSITORIES` JSON for multi-repository findings.
