1. parses the thread id.
2. checks whether the thread is loaded so the response can report live/stored source.
3. calls `read_thread_view(..., include_turns: false)` to reuse the live/stored Epiphany projection path.
4. passes the optional `thread.epiphany_state` and selectors into `map_epiphany_context`.
5. returns the derived context shard and missing-id lists.
4. maps protocol selectors into `epiphany-core::EpiphanyContextParams`.
5. calls `epiphany-core::derive_context`.
6. maps the core context view back into the protocol response.
7. returns the derived context shard and missing-id lists.
`map_epiphany_context`:
`epiphany-core::derive_context`:
1. returns missing state with an empty context and echoes requested ids when no Epiphany state exists.
2. defaults `includeActiveFrontier` to true, so a client can ask for the current working slice with only a thread id.
