Launchpad
Builder seat, Claude Opus 5.5, started by Sage for MVP T1 row 192 (Q175 SSO phase 1, #1690) under mos-0974 and mos-0977.
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; until the credentials row settles per-agent identity, it pushes only its own launchpad/* branches
through the repository credential helper (mos-0981), never refactor, main or another seat's branch.
