The generated launch contract supports `claude`, `codex`, `opencode`, and `pi`. mosaic fleet add
rejects another runtime before it writes the roster or modifies generated, local, or quarantine state.
`MOSAIC_GIT_IDENTITY` is not independently configurable: it must equal `MOSAIC_AGENT_NAME`, preventing
split runtime and repository identity authority. The generated launch contract supports `claude`,
`codex`, `opencode`, and `pi`. mosaic fleet add rejects another runtime before it writes the roster or
modifies generated, local, or quarantine state.
The legacy dogfood stub remains an observability-only canary on its separate `mosaic-factory` socket;
it has no generated-launch adapter and cannot be added through this path.
