+  // This harness exists to verify the canvas *tab UI* renders (staging-
+  // tabs.spec.ts: open each of the 13 workspace-panel tabs, assert no hard
+  // crash / no "Failed to load" toast). It does NOT exercise the agent —
+  // no LLM call is made, the spec even mocks /cp/auth/me and 401→200. All
+  // it needs is a workspace ROW that the canvas lists so the node renders
+  // and the side-panel tabs open. A fully-`online` agent is NOT required.
+  //
+  // That distinction became load-bearing on 2026-06-03: workspace-server
+  // #2162 (fix(provision): platform-managed workspace must fail-closed when
+  // CP proxy env absent) made a platform_managed workspace ABORT AT BOOT
+  // with MISSING_PLATFORM_PROXY when MOLECULE_LLM_BASE_URL /
+  // MOLECULE_LLM_USAGE_TOKEN are not present in the tenant's env. The
+  // canvas E2E creates a bare hermes/gpt-4o workspace, which defaults
+  // closed to platform_managed (workspace_provision.go:~1009), and the
+  // staging tenant does not carry the CP proxy env — so the agent never
+  // starts. Pre-#2162 this same workspace booted credential-less (the bug
+  // #2162 fixed) and the tabs rendered fine; #2162 is a correct production
+  // safety fix, but it surfaced here as `status:"failed", uptime_seconds:0,
+  // last_sample_error:null` — the pre-start credential-abort shape — and the
+  // old hard-throw turned a UI-irrelevant boot skip into a main-red
+  // (core#2199). The agent boot stage is simply not what this test gates.
+  //
+  // So: online is the happy path. A `failed` row that is the PRE-START
+  // credential-abort shape (the agent process never ran: uptime_seconds==0
+  // AND no last_sample_error) is treated as RENDERABLE — the row exists,
+  // the node + tabs render, proceed. We do NOT mask a real boot regression:
+  // any `failed` carrying a last_sample_error, OR a non-zero uptime (the
+  // agent started then crashed — image pull, panic, PYTHONPATH, etc.),
+  // still hard-throws. Genuine *infra* provision failure is already caught
+  // loud one step earlier at the org level (instance_status === "failed").
