### Forbidden knowledge
Do not drop them straight into apocalypse competence. Show misunderstanding, denial, bodies, phones, neighbors, sirens, doors. Also: no narrator future-summary language, no proof of Steve, no Part 3 radio logic.
### Objects, vehicles, supplies, body, and logistics
Track vehicles, fuel, water, food, medical bag, clean cloth, weapons, maps, Theo supplies if present, Henry belongings if present, Steve sign kit if present, Scout, Beta, sleeping arrangements, and who can physically carry what.
### Children, animals, injuries, pregnancy, and medical continuity
Children and animals are structural, not decorative. Theo and Henry require appropriate care. Scout and Beta affect movement. Wounds, infection, exhaustion, menstruation, hygiene, and sleep debt must remain continuous.
### Relationship state at opening
To be expanded in skeleton pass. Always check Clexa, Ronance, Vauseman, SwanQueen if present, plus Finchel once introduced.
### Constraints
The chapter must feel like fanfic and story, not a technical report. Logistics must be alive, voiced, intimate, funny, painful, or dangerous.
### Active-file contradictions to resolve
Check during skeleton pass against `canon_ledger.md`, `chapters_summaries.md`, `worklist_by_parts_part2.md`, and adjacent chapter entries.
### Files to update after this chapter
`chapters_summaries.md`, `part2_chapter_logic_map.md`, `worklist_by_parts_part2.md`, and `canon_ledger.md` if canon changes.

### Chapter role in Part 2
To give Vauseman a real standalone pre-Theo survival arc before motherhood arrives. The chapter proves that Alex and Piper are not together only because of the baby. They are already a messy, damaged, intimate survival unit before Theo changes the road.
### Physical opening
Immediately after Chapter 030: Alex and Piper have left the apartment with limited supplies, unfinished relationship wreckage, partial survival knowledge, and no stable route.
### Physical ending
A veterinary clinic / roadside clinic / small medical-adjacent shelter near month 9. Thea has died after childbirth. Theo is alive, newborn, unnamed, crying, fragile and physically urgent. Living dead are drawn by the sound. Alex and Piper escape with the baby and Thea's identifying object / wallet
### What the previous chapter leaves that must matter here
Chapter 030 leaves Alex and Piper outside the apartment after roughly two weeks of Day Zero collapse, with survival supplies, water/food scarcity awareness, sound-attraction learned only as a partial observed pattern, and unresolved marital intimacy. They know
