## Summary Implements `/#/roles` per QA #809 §5.4 / issue #818. The page previously showed "Page not yet implemented." ### Backend - New `GET /api/analytics/roles` returns `{ totalNodes, roles: [{ role, nodeCount, withSkew, meanAbsSkewSec, medianAbsSkewSec, okCount, warningCount, criticalCount, absurdCount, noClockCount }] }`. - Pure `computeRoleAnalytics(nodesByPubkey, skewByPubkey)` does the bucketing/aggregation — no store/lock dependency, fully unit-testable. - Roles are normalised (lowercased + trimmed; empty bucketed as `unknown`). ### Frontend - New `public/roles-page.js` renders a distribution table: count, share, distribution bar, w/ skew, median |skew|, mean |skew|, severity breakdown (OK / Warning / Critical / Absurd / No-clock). - Registered as the `roles` page in the SPA router and linked from the main nav. - Auto-refreshes every 60 s, with a manual refresh button. ### Tests (TDD) - **Red commit** (`9726d5b`): two assertion-failing tests against a stub `computeRoleAnalytics` that returns an empty result. Compiles, runs, fails on `TotalNodes = 0, want 5` and `len(Roles) = 0, want 1`. - **Green commit** (`7efb76a`): full implementation, route wiring, frontend page + nav, plus E2E test in `test-e2e-playwright.js` covering both the empty-state contract (no "Page not yet implemented" placeholder) and the populated-table case (header columns, body rows, API response shape). ### Verification - `go test ./cmd/server/...` green. - Local server with the e2e fixture: `GET /api/analytics/roles` returns `{"totalNodes":200,"roles":[{"role":"repeater","nodeCount":168,...},{"role":"room","nodeCount":23,...},{"role":"companion","nodeCount":9,...}]}`.
