### Objects, vehicles, supplies, body, and logistics
To be filled during skeleton pass. Must include any physically present vehicles, tools, weapons, water, medical supplies, signs, ropes, radios, maps, food, children supplies, animal needs, and injury constraints.
### Children, animals, injuries, pregnancy, and medical continuity
To be filled during skeleton pass. Children, animals, pregnancy, and injuries cannot disappear just because the chapter has plot pressure.
### Constraints
Show through scene logic. No reader-facing explanations, no prophecy language, no future-summary phrasing, no convenient knowledge jumps.
### How future seeds are allowed in prose
Through present-tense objects, actions, blocking, incomplete knowledge, and character-specific perception. No narrator announcement.
### Active-file contradictions to resolve
Check during the skeleton pass against `canon_ledger.md`, `chapters_summaries.md`, `worklist_by_parts_part3.md`, and any active prose master.
### Files to update after this chapter
`chapters_summaries.md`, `worklist_by_parts_part3.md`, `part3_chapter_logic_map.md`, and `canon_ledger.md` if canon changes.
### Existing planning summary
Chapter 78 is the first pressure test of the expanded convoy after it has gained an inter-vehicle language. The road breaks before they truly reach water, and the group learns that a fourth vehicle and frequencies do not erase mud, noise, children, animals, and fear.
### Chapter role in this part
The chapter must serve the water environment, marina logistics, Shoni, Seth / Summer, continued Steve signs, fragile broadcasts, and the growing truth that the convoy cannot stay road-only.
### Physical opening
To be locked during the new skeleton pass from the previous chapter's physical ending. Do not reuse old prose if it contradicts the current block order.
### What the previous chapter leaves that must matter here
Carry forward physical continuity from the previous chapter: vehicles, route, supplies, injuries, children, animals, relationship state, knowledge state, and any active object or signal.
### What the next chapter must receive from here
The next chapter must receive a clear physical handoff, not just an emotional idea: location, vehicle arrangement, who is present, who knows what, and what problem is still open.
