Fix trust-signing setup workspace branding

 | 2026-03-07 | Setup-surface QA found a canonical drift defect inside Trust & Signing: from `/setup/trust-signing`, Playwright showed in-page tabs rendering `/administration/trust-signing/*` hrefs, and clicking `Signing Keys` navigated to the retired administration tree instead of staying under setup. | QA |
 | 2026-03-07 | Fixed Trust & Signing to load directly under `setup.routes.ts`, repointed evidence-related setup/trust links to `/setup/trust-signing`, and added Playwright coverage for the canonical setup trust route and tab navigation. | Developer (FE) |
 | 2026-03-07 | Verification: the new setup trust-signing Playwright slice initially exposed a harness gap in trust API fixtures; added deterministic trust dashboard/key stubs to `prealpha-canonical-full-sweep.spec.ts`, then reran the slice successfully (`npx playwright test tests/e2e/prealpha-canonical-full-sweep.spec.ts --grep \"route works: /setup/trust-signing|setup trust-signing tabs stay under setup routes\"` -> 2/2 pass). Frontend bundle was synced into `compose_console-dist`, and live authenticated Playwright confirmed `Signing Keys` now keeps users on `https://stella-ops.local/setup/trust-signing/keys`. | QA |
+| 2026-03-07 | A follow-up live authenticated Playwright probe on `https://stella-ops.local/setup/trust-signing/keys` exposed a second trust-signing defect: the canonical setup route still rendered an `Administration` eyebrow because `trust-admin.component.ts` hard-coded the workspace label instead of deriving it from the mounted route root. | QA |
+| 2026-03-07 | Fixed the trust workspace branding leak by deriving the eyebrow label from the current route root (`setup` vs `administration`) in `trust-admin.component.ts`, tightened the canonical route expectation to require `Setup`, reran the targeted Playwright slice successfully (`npx playwright test tests/e2e/prealpha-canonical-full-sweep.spec.ts --grep \"route works: /setup/trust-signing|setup trust-signing tabs stay under setup routes\"` -> 2/2 pass), rebuilt the frontend bundle, synced `dist/stellaops-web/browser` into `compose_console-dist`, and live authenticated Playwright confirmed `/setup/trust-signing/keys` now shows `Setup` above `Trust Management`. | Developer (FE) |
 
 ## Decisions & Risks
 - Decision: this sprint stays inside `src/Web/StellaOps.Web` plus required sprint/doc updates only.
