### 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 76 returns to the convoy after the Steve block. It opens the Water Line / Shoni / Seth-Summer block that used to sit earlier. The convoy after the Waverider is already too large to pretend it is small, and the knowledge that Steve is alive now sits under every movement.
### 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.
### Physically active characters
To be locked during the new skeleton pass. Do not place a character physically in the chapter only to mark canon. They need action, body, dialogue, knowledge, or consequence.
### Characters active through speech, memory, object, or absence
Use absence as an active force only when it affects behavior, objects, signs, dialogue, or body. Steve, Lexa, Anya, the Legends, Hawkins, Shoni, Seth / Summer, or Caskett may be active this way only when the block permits it.

### Forbidden knowledge
No full Steve reunion in Part 3. No GPS solution. No stable radio rescue. No Anya learning Lexa through Steve. No Waverider magic. No side couple replacing the main core.
### 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.
