LIMITATIONS

Known limitations

- **preset generation drift (known limitation)** — `mount` re-resolves the preset by id on every creation/resume, so editing a preset file between continuable turns hands later turns a NEWER generation of that preset (the official `composeFrom` path joins the parent's exact standing instance instead). Documented behavior; restore the preset to its original state to keep turns consistent. - **Failure semantics** — like the official foreground subagent tool, a child that ends with `error` / `refusal` / `max-tokens` makes the tool call THROW (with any partial output attached); only `completed` and caller-initiated `aborted` return as values. Low-level LLM error details live in the child session log. - **Pre-check is conditional** — the model pre-check runs only when the harness exposes an `llm` service AND a provider route exists (explicit `provider` or the parent's). Without either, it is skipped and the call proceeds. - **Provider availability is environment-specific** — the pre-check validates against the runtime model catalog, but a reachable provider with a valid key is still required for the call to succeed.
