Per-bottle git-gate state (bare repos under /git/<id>, deploy creds under /git-gate/creds/<id>) was provisioned once at bottle launch and lived only in the gateway's ephemeral storage. A gateway rebuild/restart wiped it and nothing re-provisioned already-running bottles, so their agents 404'd on fetch/push. Same class of bug as the CA (#510); the orchestrator restores only egress tokens, not git-gate declarations. Persist the state on both backends, mirroring the CA-persistence approach: - firecracker: attach a second persistent data drive (/dev/vdc) to the gateway VM and bind-mount its git/ + creds/ subdirs onto /git and /git-gate/creds in the gateway guest init, before the data plane starts. Generalize the VM config to a stable-ordered data_drives tuple (CA=vdb, git=vdc; orchestrator registry stays vdb). - docker: bind-mount host dirs (host_gateway_git_dir / creds_dir, under the never-pruned app-data root) onto /git and /git-gate/creds, with BOT_BOTTLE_DOCKER_GIT_MOUNT / _CREDS_MOUNT env overrides so CI isolates them to per-run volumes it cleans up. Teardown already rm -rf's /git/<id> + creds, so the persistent store self-cleans over the normal lifecycle. Closes #512 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
