<objective> Add a backlog item to the huntmap using 999.x numbering. Backlog items are unsequenced ideas that aren't ready for active planning — they live outside the normal phase sequence and accumulate context over time. </objective> <process> 1. **Read HUNTMAP.md** to find existing backlog entries: ```bash cat .planning/HUNTMAP.md ``` 2. **Find next backlog number:** ```bash NEXT=$(node ".github/thrunt-god/bin/thrunt-tools.cjs" phase next-decimal 999 --raw) ``` If no 999.x phases exist, start at 999.1. 3. **Create the phase directory:** ```bash SLUG=$(node ".github/thrunt-god/bin/thrunt-tools.cjs" generate-slug "$ARGUMENTS") mkdir -p ".planning/phases/${NEXT}-${SLUG}" touch ".planning/phases/${NEXT}-${SLUG}/.gitkeep" ``` 4. **Add to HUNTMAP.md** under a `## Backlog` section. If the section doesn't exist, create it at the end: ```markdown ## Backlog ### Phase {NEXT}: {description} (BACKLOG) **Goal:** [Captured for future planning] **Hypotheses:** TBD **Plans:** 0 plans Plans: - [ ] TBD (promote with /thrunt-review-backlog when ready) ``` 5. **Commit:** ```bash node ".github/thrunt-god/bin/thrunt-tools.cjs" commit "docs: add backlog item ${NEXT} — ${ARGUMENTS}" --files .planning/HUNTMAP.md ".planning/phases/${NEXT}-${SLUG}/.gitkeep" ``` 6. **Report:** ``` ## 📋 Backlog Item Added Phase {NEXT}: {description} Directory: .planning/phases/{NEXT}-{slug}/ This item lives in the back
