Coordinator and Scribe's charter disagree on who writes session and orchestration logs #2454

Found in the Claude Code end-to-end test for epic #2438 (fresh repo, dev build, 2026-11-10).

What happens: after a batch of work, the coordinator spawns Scribe and asks it to write a session log to .squad/log/ and an entry to .squad/orchestration-log/ (coordinator digest, item 11). Scribe declined both and said: "I did not write the session log or the orchestration log, because my charter rules them out." In the later build session, a session log did get written, but .squad/orchestration-log/ stayed empty.

Why it matters: two Squad sources give Scribe opposite instructions, so the logs depend on which one the model follows on the day.

Suggested fix: decide who owns the session and orchestration logs, then align the coordinator digest (client/adapters/coordinator.ts, item 11) and Scribe's charter template to match.
