Resume interrupted work. Find the continue file (`{{sliceId}}-CONTINUE.md` or `continue.md`) in slice {{sliceId}} of milestone {{milestoneId}}, read it, and use it as the recovery contract for where to pick up. Before you create any expected artifact or output file, check whether it already exists and read it first — a prior session may already have started or completed that work. Do **not** delete the continue file immediately. Keep it until the task is successfully completed or you have written a newer summary/continue artifact that clearly supersedes it. If the resumed attempt fails again, update or replace the continue file so no recovery context is lost. {{skillActivation}}
