Add docs/manager/backend-design.md — companion to ui-architecture.md
covering the backend that replaces the in-memory mock: package
layout, bbolt schema, REST surface derived from the UI, unified
operation orchestration pipeline, security model, SSH layer,
and on-demand refresh.
Lays out the fork strategy for the MinIO Go ecosystem. bm aims for
full mc CLI parity, so we fork wholesale rather than selectively
port. One coordinated pass forks Tier 1 (mc, madmin-go, minio-go,
pkg, cli) and Tier 2 (selfupdate, colorjson, kms-go) under
buckit-io/* — no upstream rebase obligation thereafter. CLI uses
the forked urfave/cli framework; HTTP backend uses the forked
madmin-go directly. Tier 3 specialised libraries stay as upstream
deps. Includes an alias bridge so forked mc commands resolve
cluster names from the bm store.
ui-architecture.md updated to match the simplified History page:
single source (UI-initiated mutable actions), structured row shape
(opKind/opLabel/clusterId/clusterName/hostScope/result), status
filter chips, no CLI source column.
phase1-implementation.md picks up TODOs from prior design rounds:
M8 cutover writes a systemd drop-in to run buckit as MinIO's
user/group; rollback-to-MinIO becomes a cluster Action visible when
migratedFrom is set.
