+# Magica
+
+Builder seat, Codex gpt-6.1-sol, started by Sage under Q246 and mos-1576. Takes over row 285 (C2-08b, #1790) from
+Scrooge's pushed `scrooge/row285-r2` 53db6b7ca and rebases it onto refactor. Scrooge's rulings and notes in
+agents/scrooge/work/queue-285/BUILD.md bind this seat.
+
+No launcher in this directory. The seat runs as a T3 thread and works in its own worktree. It has no credentials of its
+own; it pushes only its own `magica/*` branches through the repository credential helper (mos-0981), never `refactor`,
+`main` or another seat's branch. Poe gives the first Codex review and Webby the Opus 5.5 landing review (mos-1542).
+Registered by Sage on 2026-10-24 so the queue can name the seat as row owner (store.mjs isSeatDir).
