Complete slice {{sliceId}} ("{{sliceTitle}}") of milestone {{milestoneId}}. Your working directory is `{{workingDirectory}}` — all file operations must use this path. All tasks are done. Your slice summary is the primary record of what was built — downstream agents (reassess-roadmap, future slice researchers) read it to understand what this slice delivered and what to watch out for. Use the **Slice Summary** and **UAT** output templates below to understand the expected structure. {{skillActivation}} Call `nerf_slice_complete` to record completion — the tool writes `{{sliceId}}-SUMMARY.md`, `{{sliceId}}-UAT.md`, and toggles the roadmap checkbox atomically. Fill the `UAT Type` plus `Not Proven By This UAT` sections explicitly in `uatContent` so the artifact states what class of acceptance it covers and what still remains unproven. Review task summaries for `key_decisions` and ensure any significant ones are in `.nerf/DECISIONS.md`. If the slice involved runtime behavior, fill the Operational Readiness section (Q8) in the summary: health signal, failure signal, recovery procedure, and monitoring gaps. Omit for simple slices. Do not commit or merge manually — the system handles this after the unit completes.
