Fix mission board reachability navigation

 | 2026-03-06 | Live mission-board interaction probe found a second routing defect: the visible `View SBOM` action linked to `/security/sbom/lake`, which stayed on that URL but rendered dashboard fallback content. Direct navigation proved the intended surface is `/security/sbom-lake`. | QA |
 | 2026-03-06 | Fixed the mission-board SBOM action to point at `/security/sbom-lake` and extended `prealpha-canonical-full-sweep.spec.ts` to cover both the canonical SBOM Lake route and the dashboard click-through path. | Developer (FE) |
 | 2026-03-06 | Verification: targeted Playwright slice passed locally (`npx playwright test tests/e2e/prealpha-canonical-full-sweep.spec.ts --grep \"sbom-lake|mission board SBOM card opens SBOM Lake\"` -> 2/2 pass). Frontend bundle rebuilt, synced into `compose_console-dist`, and live authenticated Playwright confirmed the mission-board `View SBOM` action now lands on `https://stella-ops.local/security/sbom-lake` with `SBOM Lake` / `Attestation Coverage Metrics` visible. | QA |
+| 2026-03-06 | Follow-up mission-board QA found a semantic navigation defect: Playwright DOM capture showed both Reachability card actions (`View reachability`, `Deep analysis`) pointing at `/security/findings` even though the working canonical reachability surface is `/security/reachability`. | QA |
+| 2026-03-06 | Updated the mission-board Reachability card actions to target `/security/reachability` and added focused Playwright coverage for the canonical reachability route plus the mission-board click-through. | Developer (FE) |
