Why: /api/plugins now merges compiled-in plugins (backend.mode=inproc);
the list needed to badge them as builtin, count their commands, and stop
printing a dangling "v" when the synthesized manifest has no version.
Evidence: npx vitest run 100/100 green incl. design-guard; tsc --noEmit
clean for src (../ui errors are the symlinked-deps environment only);
CI (make test) is authoritative.
Impact: PluginsSection label hides empty versions, desc adds a command
count and falls back to manifest intent counts, and inproc entries get a
"内置" badge next to the api badge. No token or color changes.
Refs: WP3-I4; task card feature-plugins-compiled-listing.
Why: seeded sections carry no confirmed trace edges yet, so the no-relations empty state is the correct U4 presentation.
Evidence: scripts/e2e.sh rerun in this task.
Impact: test-only.
Why: rdm.inspect.tree docs is two-level (parent=<docId> returns sections), but the U4 workspace only fetched level one - the tree showed bare documents, clicking a doc hit unsupported inspect.object kind, and the trace tab always showed no sections.
Evidence: tsc + design-guard green; scripts/e2e.sh full run in this task.
Impact: tree browsing expands documents into sections; trace entry lists sections aggregated per document.
Refs: U4/U3 read-service contract; task feature/rdm-e2e-acceptance.
Why: the first docs-tree node is document-level and carries no event history; U4 evidence-finding targets sections.
Evidence: scripts/e2e.sh rerun in this task.
Impact: test-only.
Why: buildWorkspaceEntries pushed only BUILTINS[0] (agents); the U4
rdm-audit workspace was declared but never ranked, so no user could
open the trace/audit workspace from the sidebar.
Evidence: vitest workspaces.test.ts 4/4 (updated expectations plus a
new overflow-truncation case); full browser run in scripts/e2e.sh.
Impact: sidebar gains the second builtin tool; server-declared
workspaces keep their shortcut precedence.
Refs: U4 (Dev #368) regression; task feature/rdm-e2e-acceptance.
Why: U4 acceptance requires real-browser runs of the trace/audit
workspace; the repo had only a manual .playwright.ts stub gated on
PLAYWRIGHT_BASE_URL with no config, deps, or service wiring.
Evidence: config/deps/spec staged; full run driven by Dev-side
scripts/e2e.sh (seed-only smoke in progress in this task branch).
Impact: dev-only additions (@playwright/test devDep, preview proxy
segment, e2e/rdm-audit.playwright.ts); no production bundle changes.
