The analyst flow becomes a closed loop with the server-curated table catalog:
- `da analyst setup` writes `<workspace>/.claude/settings.json` with two hooks:
SessionStart → `da sync --quiet || true` — pulls fresh RBAC-filtered parquets at session start
SessionEnd → `da sync --upload-only --quiet || true` — uploads session jsonl + CLAUDE.local.md
- `|| true` keeps Claude Code unblocked when the server is down.
- Workspace-level (not user-home) so the hooks fire only when Claude Code opens this analyst workspace.
- `da sync --quiet` rewrites the CLI output for hook consumption — 0 stdout on success, single-line error on failure.
- Existing settings.json is patched (deep-merged), not overwritten; malformed JSON is reported, not silently overwritten.
Tests cover: workspace bootstrap, hook insertion, malformed-json safety, quiet-mode output shape.
